FIELD OF THE INVENTION
[0002] The present invention relates to interferon-free and
ribavirin-free treatment for hepatitis C virus (HCV).
BACKGROUND OF THE INVENTION
[0003] The HCV is an RNA virus belonging to the Hepacivirus genus
in the Flaviviridae family. The enveloped HCV virion contains a
positive stranded RNA genome encoding all known virus-specific
proteins in a single, uninterrupted, open reading frame. The open
reading frame comprises approximately 9500 nucleotides and encodes
a single large polyprotein of about 3000 amino acids. The
polyprotein comprises a core protein, envelope proteins E1 and E2,
a membrane bound protein p7, and the non-structural proteins NS2,
NS3, NS4A, NS4B, NS5A and NS5B.
[0004] Chronic HCV infection is associated with progressive liver
pathology, including cirrhosis and hepatocellular carcinoma.
Chronic hepatitis C may be treated with peginterferon-alpha in
combination with ribavirin. Substantial limitations to efficacy and
tolerability remain as many users suffer from side effects, and
viral elimination from the body is often incomplete. Therefore,
there is a need for new therapies to treat HCV infection.
BRIEF SUMMARY OF THE INVENTION
[0005] As one aspect of the present invention, methods for treating
HCV infection in a subject are provided. The methods comprise
administering at least two direct acting antiviral agents (DAAs)
for a duration of no more than twelve weeks, or for another
duration as set forth herein. Preferably, the duration of the
treatment is twelve weeks. The duration of the treatment can also
be no more than eight weeks. Preferably, the two or more direct
acting antiviral agents (DAAs) are administered in amounts
effective to provide a sustained virological response (SVR) or
achieve another desired measure of effectiveness in a subject. The
subject is not administered ribavirin during the duration of
administering the at least two DAAs. Put another way, the methods
exclude the administration of ribavirin to the subject during the
treatment regimen. The subject is also not administered interferon
during the treatment regimen. Put another way, the methods exclude
the administration of interferon to the subject, thereby avoiding
the side effects associated with interferon. In some embodiments,
the methods further comprise administering an inhibitor of
cytochrome P-450 (such as ritonavir) to the subject to improve the
pharmacokinetics or bioavailability of one or more of the DAAs.
[0006] As another aspect, methods for treating HCV infection in a
subject are provided. The methods comprise administering (a)
therapeutic agent 1, (b) at least one polymerase inhibitor selected
from the group consisting of therapeutic agent 2, therapeutic agent
3, and combinations thereof, and (c) an inhibitor of cytochrome
P-450 to the subject for a duration of no more than twelve weeks,
or for another duration as set forth herein (e.g., the treatment
regimen can last for a duration of no more than 8 weeks).
Preferably, therapeutic agent 1, the polymerase inhibitor(s), and
the inhibitor of cytochrome P-450 are administered in amounts
effective to provide high rates of SVR or another measure of
effectiveness in the subject. As non-limiting examples, therapeutic
agent 1 and the inhibitor of cytochrome P-450 can be co-formulated
and administered once daily, and the polymerase inhibitor(s) can be
administered once daily or twice daily, and the treatment regimen
preferably lasts for twelve weeks (the treatment regimen can also
last, for example, for eight weeks).
[0007] As still another aspect, methods for treating a population
of subjects having HCV infection are provided. The methods comprise
administering at least two DAAs to the subjects for a duration of
no more than 12 weeks. Preferably, the at least two DAAs are
administered to the subjects in amounts effective to result in SVR
or another measure of effectiveness in at least about 50% of the
population, preferably at least about 70% of the population.
[0008] In the foregoing methods as well as methods described
hereinbelow, the DAAs can be selected from the group consisting of
protease inhibitors, nucleoside or nucleotide polymerase
inhibitors, non-nucleoside polymerase inhibitors, NS3B inhibitors,
NS4A inhibitors, NS5A inhibitors, NS5B inhibitors, cyclophilin
inhibitors, and combinations of any of the foregoing. For example,
in some embodiments, the DAAs used in the present methods comprise
or consist of at least one HCV protease inhibitor and at least one
HCV polymerase inhibitor. The HCV polymerase inhibitor can be a
nucleotide or nucleoside polymerase inhibitor or a non-nucleoside
polymerase inhibitor. The HCV polymerase inhibitor can also be a
non-nucleotide polymerase inhibitor.
[0009] In some embodiments, the HCV protease inhibitor is
therapeutic agent 1 (described below) and the HCV polymerase
inhibitor is therapeutic agent 2 and/or therapeutic agent 3 (also
described below). By way of example, therapeutic agent 1 is
administered a total daily dose of from about 100 mg to about 250
mg, or administered at least once daily at a dose of from about 150
mg to about 250 mg, and therapeutic agent 2 is administered in a
total daily dose of from about 300 mg to about 1800 mg or
administered at least twice daily at doses from about 200 mg to
about 400 mg. For some embodiments, the HCV protease inhibitor is
therapeutic agent 1 and the non-nucleoside HCV polymerase inhibitor
is therapeutic agent 3. By way of example, therapeutic agent 1 can
be administered at a total daily dose of about 100 mg,
alternatively about 200 mg, or alternatively about 250 mg; and
therapeutic agent 3 is administered at a total daily dose of about
400 mg. Ritonavir (or another cytochrome P-450 3A4 inhibitor) can
be co-administered with therapeutic agent 1 to improve the
pharmacokinetics and bioavailability of therapeutic agent 1.
[0010] In some embodiments, the at least two DAAs comprise at least
one HCV protease inhibitor and at least one NS5A inhibitor.
Preferably, the HCV protease inhibitor is therapeutic agent 1 and
the NS5A inhibitor is therapeutic agent 4. By way of example,
therapeutic agent 1 can be administered at a total daily dosage
from about 100 mg to about 250 mg, and therapeutic agent 4 can be
administered in a total daily dose from about 25 mg to about 200
mg. Ritonavir (or another cytochrome P-450 3A4 inhibitor) can be
co-administered with therapeutic agent 1 to improve the
pharmacokinetics and bioavailability of therapeutic agent 1.
[0011] In the foregoing methods as well as methods described
herein, the DAAs can be administered in any effective dosing
schemes and/or frequencies, for example, they can each be
administered daily. Each DAA can be administered either separately
or in combination, and each DAA can be administered at least once a
day, at least twice a day, or at least three times a day. In some
preferred embodiments, therapeutic agent 3 is administered once
daily (QD) or twice daily (BID), and therapeutic agent 1 is
administered once daily.
[0012] In some aspects, the present technology provides a method
for treating HCV infection comprising administering to a subject in
need thereof at least two DAAs for a duration of no more than
twelve weeks, wherein the subject is not administered with either
interferon or ribavirin during said duration. In some aspects, the
at least two DAAs are administered in an amount effective to result
in SVR. Some methods further comprise administering an inhibitor of
cytochrome P450 to the subject. In some aspects, the duration is no
more than eight weeks.

the method comprising administering at least two DAAs to the
subjects for a duration of no more than 12 weeks, wherein the at
least two DAAs are administered to the subjects in amounts and for
a duration effective to provide a SVR in at least about 70% of the
population.
[0020] In another aspect, the present technology features a
combination of at least two DAAs for use in treating HCV infection,
wherein the duration of the treatment regimen is no more than
twelve weeks (e.g., the duration being 12 weeks; or the duration
being 11, 10, 9, 8, 7, 6, 5, 4, or 3 weeks). Preferably, the
duration of the treatment regimen is twelve weeks. The duration of
the treatment can also last, for example, no more than eight weeks
(e.g., the duration being 8 weeks; or the duration being 7, 6, 5,
4, or 3 weeks). The treatment comprises administering the at least
two DAAs to a subject infected with HCV. The treatment does not
include administering interferon or ribavirin. The treatment may
include administering ritonavir or another CYP3A4 inhibitor (e.g.,
cobicistat) if one of the DAAs requires pharmacokinetic
enhancement. The at least two DAAs can be administered concurrently
or sequentially. For example, one DAA can be administered once
daily, and another DAA can be administered twice daily. For another
example, the two DAAs are administered once daily. For yet another
example, the two DAAs are co-formulated in a single composition and
administered concurrently (e.g., once daily). As a non-limiting
example, the patient being treated can be infected with HCV
genotype 1, such as genotype 1a or 1b. As another non-limiting
example, the patient can be infected with HCV genotype 2 or 3. As
yet another non-limiting example, the patient can be a
HCV-treatment naive patient, a HCV-treatment experienced patient,
an interferon non-responder (e.g., a null responder, a partial
responder, or a relapser), or not a candidate for interferon
treatment.
[0021] In another aspect, the present technology features a
combination of Compound 1 (or a pharmaceutically acceptable salt
thereof) and Compound 2 (or a pharmaceutically acceptable salt
thereof) for use in treating HCV infection. The treatment comprises
administering the DAAs to a subject infected with HCV. The duration
of the treatment regimen is no more than twelve weeks (e.g., the
duration being 12 weeks; or the duration being 11, 10, 9, 8, 7, 6,
5, 4, or 3 weeks). Preferably, the duration of the treatment
regimen is twelve weeks. The duration of the treatment can also
last, for example, no more than eight weeks (e.g., the duration

[0110] The current standard of care (SOC) for the treatment of HCV
includes a course of treatment of interferon, e.g. pegylated
interferon (e.g., pegylated interferon-alpha-2a or pegylated
interferon-alpha-2b, such as PEGASYS by Roche, or PEG-INTRON by
Schering-Plough) and the antiviral drug ribavirin (e.g., COPEGUS by
Roche, REBETOL by Schering-Plough, or RIBASPHERE by Three Rivers
Pharmaceuticals). The treatment often lasts for 24-48 weeks,
depending on hepatitis C virus genotype. Other interferons include,
but are not limited to, interferon-alpha-2a (e.g., Roferon-A by
Roche), interferon-alpha-2b (e.g., Intron-A by Schering-Plough),
and interferon alfacon-1 (consensus interferon) (e.g., Infergen by
Valeant). Less than 50% of patients with chronic HCV infection with
genotype 1 virus respond to this therapy. Further, interferon
therapy has many side effects that hinder patient compliance and
results in premature discontinuation of the treatment.
[0111] The interferon/ribavirin-based treatment may be physically
demanding, and can lead to temporary disability in some cases. A
substantial proportion of patients will experience a panoply of
side effects ranging from a "flu-like" syndrome (the most common,
experienced for a few days after the weekly injection of
interferon) to severe adverse events including anemia,
cardiovascular events and psychiatric problems such as suicide or
suicidal ideation. The latter are exacerbated by the general
physiological stress experienced by the patients. Ribavirin also
has a number of side effects, including, anemia, high pill burden
(e.g. 5-6 pills a day split BID) and teratogenicity restricting use
in women of childbearing age.
[0112] The present methods provide effective treatment of HCV
infection without the use of interferon or ribavirin and for a
shorter period of time, such as a treatment duration of no more
than twelve weeks, alternatively no more than eleven weeks,
alternatively no more than ten weeks, alternatively no more than
nine weeks, alternatively no more than eight weeks, alternatively
no more than seven weeks, alternatively no more than six weeks,
alternatively no more than five weeks, alternatively no more than
four weeks, or alternatively, no more than three weeks.
[0113] In some embodiments, the present technology provides methods
for treating HCV infection in a subject comprising administering at
least two DAAs in the absence of interferon and ribavirin for a
duration of no more than twelve weeks, alternatively no more than
eight weeks. Put another way, the present methods exclude
interferon and ribavirin, or the subject does not receive
interferon or ribavirin for the duration of the treatment. The at
least two DAAs can be co-administered or can be administered
independently (with the same or different dosing frequencies) and
can be administered once a day, alternatively twice a day,
alternatively three times a day.
[0114] In some embodiments, the methods of treatment comprise daily
administration of two or more DAAs, wherein a first DAA may be
administered once a day, twice a day, or three times a day, and a
second DAA may be administered once a day, twice a day, or three
times a day. In some embodiments, a third DAA may be administered
once a day, twice a day, or three times a day. The DAAs may be
co-administered or administered at different times or frequencies.
Preferably, in the methods, at least two DAAs are administered in
effective amounts to provide a desired measure of effectiveness in
the subject. Preferably, the treatment has reduced side effects as
compared with interferon-containing treatments.
[0115] Various measures may be used to express the effectiveness of
the present methods of HCV treatment. One such measure is rapid
virological response (RVR), meaning that HCV is undetectable in the
subject after 4 weeks of treatment, for example, after 4 weeks of
administration of two or more of DAAs. Another measure is early
virological response (EVR), meaning that the subject has >2
log.sub.10 reduction in viral load after 12 weeks of treatment.
Another measure is complete EVR (cEVR), meaning the HCV is
undetectable in the serum of the subject after 12 weeks of
treatment. Another measure is extended RVR (eRVR), meaning
achievement of RVR and cEVR, that is, HCV is undetectable at week 4
and 12. Another measure is the presence or absence of detectable
virus at the end of therapy (EOT). Another measure is SVR, which,
as used herein, means that the virus is undetectable at the end of
therapy and for at least 8 weeks after the end of therapy (SVR8);
preferably, the virus is undetectable at the end of therapy and for
at least 12 weeks after the end of therapy (SVR12); more
preferably, the virus is undetectable at the end of therapy and for
at least 16 weeks after the end of therapy (SVR16); and highly
preferably, the virus is undetectable at the end of therapy and for
at least 24 weeks after the end of therapy (SVR24). SVR24 is often
considered as a functional definition of cure; and a high rate of
SVR at less than 24 week post-treatment (e.g., SVR8 or SVR12) can
be predictive of a high rate of SVR24. Likewise, a high rate of SVR
at less than 12 week post-treatment (e.g., SVR4 or SVR8) can be
predictive of a high rate of SVR12. A high rate of EOT (e.g., at
week 8 or week 12) can also be indicative of a significant rate of
SVR12 or SVR24.
[0116] In some embodiments, the amounts of the two or more DAAs,
and/or the duration of the treatment regimen of the two or more
DAAs, are effective to provide an RVR in a subject, or an EVR in a
subject, or a cEVR in a subject, or an eRVR in a subject, or an
absence of detectable virus at EOT in a subject. In some
embodiments, the present methods comprise treating a population of
subjects having HCV infection (e.g. treatment naive subjects), and
the methods comprise administering at least two DAAs to the
subjects for a duration of no more than 12 weeks, or for another
duration disclosed herein, wherein the at least two DAAs are
administered to the subjects in amounts effective to provide an SVR
(e.g., SVR after 8 weeks post-treatment, or SVR after 24 weeks
post-treatment) in at least about 70% of the population,
alternatively at least about 75% of the population, alternatively
at least about 80% of the population, alternatively at least about
85% of the population, alternatively at least about 90% of the
population, alternatively at least about 95% of the population,
alternatively about 100% of the population. In some embodiments,
the present methods comprise treating a population of IFN
experienced subjects (e.g., interferon non-responders) having HCV
infection, and the methods comprise administering at least two DAAs
to the subjects for a duration of no more than 12 weeks, or for
another duration disclosed herein, wherein the at least two DAAs
are administered to the subjects in amounts effective to provide an
SVR (e.g., SVR after 8 weeks post-treatment, or SVR after 24 weeks
post-treatment) in at least about 50% of the population,
alternatively at least about 55% of the population, alternatively
at least about 60% of the population, alternatively at least about
65% of the population. In other embodiments, the amount of DAAs and
the duration of the treatment are effective to provide one or more
of an SVR (e.g., SVR after 8 weeks post-treatment, or SVR after 24
weeks post-treatment), an RVR, an EVR, a cEVR, an eRVR, or an
absence of detectable virus at EOT, in at least about 50% of the
population, alternatively at least about 55%, in at least about 60%
of the population, alternatively at least about 65% of the
population, alternatively at least about 70% of the population,
alternatively at least about 75% of the population, alternatively
at least about 80% of the population, alternatively at least about
85% of the population, alternatively at least about 90% of the
population, alternatively at least about 95% of the population,
alternatively about 100% of the population. For example, the
present methods comprise administering at least two DAAs in amounts
and for durations effective to provide an SVR (e.g., SVR after 8
weeks post-treatment, or SVR after 24 weeks post-treatment) in a
subject. In some embodiments, the present technology provides for
an SVR (e.g., SVR after 8 weeks post-treatment, or SVR after 24
weeks post-treatment) in at least about 50% of the population,
alternatively at least about 55% of the population, in at least
about 60% of the population, preferably in at least about 65% of
the population, preferably in at least about 70% of the population,
preferably at least about 75% of the patients treated by such
methods herein described, more preferably in at least 80% of the
population, and highly preferably in at least about 90% of the
patients being treated. In some embodiments, a treatment of the
present technology provides an RVR or undetectable level of HCV RNA
in the bloodstream at four (4) weeks of treatment (preferably in
addition to a SVR).
[0117] A DAA of the present technology includes, but is not limited
to, a protease inhibitor, a HCV polymerase inhibitor, an HCV NS5A
inhibitor, an HCV NS3B inhibitor, an HCV NS4A inhibitor, an HCV
NS5B inhibitor, an HCV entry inhibitor, a cyclophilin inhibitor, a
CD81 inhibitor, or an internal ribosome entry site inhibitor. The
HCV polymerase inhibitor may be a nucleoside or nucleotide
polymerase inhibitor or a non-nucleoside polymerase inhibitor. The
HCV polymerase inhibitor may be a nucleotide polymerase inhibitor
or a non-nucleotide polymerase inhibitor.
[0118] In yet another example of this aspect of the technology, the
combination of two or more DAAs comprises PSI-7977 and PSI-938. In
yet another example, the combination of two or more DAAs comprises
PSI-7977 and TMC-435. In yet another example, the combination of
two or more DAAs comprises BMS-790052 and BMS-650032. In yet
another example, the combination of two or more DAAs comprises
GS-5885, GS-9190, and GS-9451. In yet another example, the
combination of two or more DAAs comprises BI-201335 and BI-207127.
In yet another example, the combination of two or more DAAs
comprises telaprevir and VX-222. In another example, the
combination of two or more DAAs comprises GS-5885 and GS-9451. In
yet another example, the combination of two or more DAAs includes
danoprevir (with ritonavir) and R7128. In yet another example, the
combination of two or more DAAs includes PSI-7977 and BMS-790052
(daclatasvir). In yet another example, the combination of two or
more DAAs includes PSI-7977 and BMS-650032 (asunaprevir). In still
another example, the combination of two or more DAAs includes
PSI-7977, BMS-650032 (asunaprevir) and BMS-790052 (daclatasvir). In

(asunaprevir). In still another example, the combination of two or
more DAAs includes INX-189, BMS-650032 (asunaprevir) and BMS-790052
(daclatasvir).
[0119] It was unexpected that an interferon-free and ribavirin-free
treatment using a combination of two or more DAAs, and for a
duration of no more than 12 weeks, can achieve significant SVR. In
some cases, such a treatment can achieve an SVR in at least about
75% of patients, and in some cases, such a treatment can achieve an
SVR in at least about 85% of patients, and in certain cases, such a
treatment can achieve an SVR in at least about 90% of patients. It
was also unexpected that an interferon-free and ribavirin-free
treatment using a combination of two or more DAAs, and for a
duration of no more than 12 weeks, may achieve significant SVR in
interferon non-responders (e.g., null responders), for example,
such a treatment may achieve an SVR in at least about 50% of
patients in the interferon non-responder population, preferably at
least about 60% of patients in the interferon non-responder
population, more preferably at least about 65% of patients in the
interferon non-responder population.
[0120] Accordingly, in one aspect, the present technology features
a method of treating HCV infection, comprising administering to a
patient in need thereof an effective amount of a combination of two
or more DAAs. The treatment lasts 8 weeks and does not include
administration of any interferon or ribavirin. The DAAs can be
administered at the same or different dosing frequencies. The
patient being treated can be a treatment naive patient, a treatment
experienced patient, including, but not limited to, a relapser, an
interferon partial responder, or an interferon non-responder; or a
patient unable to take interferon. The patient may be infected
with, for example and without limitation, HCV genotype 1, such as
HCV genotype 1a or HCV genotype 1b; or HCV genotype 2 or 3. The
treatment according to this aspect of the technology may also be
effective against other HCV genotypes. The DAAs can be administered
around the same time or at different times, and can be
co-formulated in a single formulation or formulated in different
compositions. Each DAA can be selected from HCV protease
inhibitors, HCV polymerase inhibitors, or HCV NS5A inhibitors. For

polymerase inhibitor, or a combination of at least two
non-nucleoside polymerase inhibitors). For another instance, the

DAA(s) can also be included in a treatment regimen according to
this aspect of the technology.
[0132] In another embodiment, the present technology provides
interferon- and ribavirin-free treatment comprising administering
daily two DAAs, where the two DAAs include a HCV polymerase
inhibitor, for example PSI-7977 and a NS5A inhibitor, for example
BMS-790052 for a duration of no more than twelve weeks (e.g., no
more than eleven weeks), preferably no more than eight weeks.
[0133] In some embodiments, the present technology provides a
method of treating Hepatitis C virus infection in a subject
comprising administering daily a HCV protease inhibitor and a HCV
polymerase inhibitor to the subject in the absence of interferon
and ribavirin for a duration of no more than twelve weeks,
preferably no more than eight weeks. In some embodiments, ritonavir
(or an equivalent thereof) is co-administered with one or more
protease inhibitors to improve the pharmacokinetics of the protease
inhibitor(s). The treatment excludes administering ribavirin to the
patient. In some embodiments, the HCV polymerase inhibitor is at
least one nucleoside or nucleotide polymerase inhibitor or at least
one non-nucleoside polymerase inhibitor. In some embodiments, both
a nucleoside or nucleotide polymerase inhibitor and a
non-nucleoside polymerase inhibitor may be administered.
[0134] The methods of the present technology as described herein
may be used to treat a naive patient or a treatment experienced
patient. Treatment experienced patients include interferon
non-responders (e.g., null responders), partial responders
(patients whose HCV RNA levels declined but never became
undetectable), and relapsers (patients who achieved undetectable
levels of HCV RNA during therapy but rebound). Methods of the
present technology may also be used to treat patients who are not
candidates for interferon treatment. Patients who are not
candidates for interferon treatment include, but are not limited
to, one or more of the following groups: patients intolerant to
interferon, patients who refuse to take interferon treatment,
patients with medical conditions which preclude them from taking
interferon, and patients who have an increased risk of side effects
or infection by taking interferon.
[0135] In some embodiments, a cytochrome P-450 inhibitor, e.g.
ritonavir, is administered either in the same or separate
pharmaceutical composition with the protease inhibitor (e.g.
Compound 1 (or a pharmaceutically acceptable salt thereof)) to
improve the pharmacokinetics. A cytochrome P450 inhibitor reduces
the metabolism of some protease inhibitors, such as Compound 1,
thereby improving the pharmacokinetics and bioavailability of the
protease inhibitor, for example Compound 1. More preferably,
Compound 1 (or a pharmaceutically acceptable salt thereof) is
co-formulated with ritonavir in the same dosage form. Other
cytochrome P450 inhibitors, such as cobicistat, may also be
administered in lieu of ritonavir, to enhance the pharmacokinetics
of Compound 1 (or a pharmaceutically acceptable salt thereof).
[0136] Inhibitors of cytochrome P450, such as ritonavir, may be
co-administered with the DAAs, either sequentially or
simultaneously, in the same or different compositions. In some
embodiments, the cytochrome P450 inhibitors are administered in
order to improve the pharmacokinetics of at least one of the DAAs.
Not to be bound by any theory, but a cytochrome P450 inhibitor may
also reduce the development of resistant strains of HCV when
co-administered with a DAA, thus providing the effectiveness in a
shorter treatment. In some embodiments, ritonavir is
co-administered with therapeutic agent 1. In some embodiments,
ritonavir is co-administered with therapeutic agent 1 in the same
compositions.
[0137] In some embodiments, the present technology provides a
method of treating HCV infection comprising administering at least
one protease inhibitor and at least one HCV polymerase inhibitor in
a course of treatment of no more than, or less than, eight weeks in
the absence of interferon and ribavirin. In some embodiments, the
HCV polymerase inhibitor is Compound 1 (or a pharmaceutically
acceptable salt thereof).
[0138] In some embodiments, the present technology provides a
method of treating HCV infection without using interferon and
ribavirin, the method comprising administering at least two DAAs to
a patient in need of such treatment, wherein the at least two DAAs
include at least one protease inhibitor and at least one HCV
polymerase inhibitor. In some embodiments, the at least two DAAs
includes therapeutic agent 1 with at least one HCV polymerase
inhibitor. In some embodiments, the HCV polymerase inhibitor is at
least one non-nucleoside polymerase inhibitor. In some embodiments,
the non-nucleoside polymerase inhibitor is therapeutic agent 2 or
therapeutic agent 3 or a combination thereof.
[0139] In some embodiments, the present technology provides a
method of treating HCV infection without using interferon and
ribavirin, the method comprising administering a HCV protease
inhibitor, preferably therapeutic agent 1, with at least one HCV
NSSA inhibitor to a patient in need of such treatment. In some
embodiments, the NSSA inhibitor is therapeutic agent 4.
[0140] In some embodiments of the present technology, a method of
treating HCV infection without using interferon and ribavirin, the
method comprises administering at least three DAAs to a subject for
no more than 8 weeks without administering interferon or ribavirin.
The at least three DAAs can be at least one protease inhibitor, at
least one HCV polymerase inhibitor, and at least one NSSA
inhibitors. In a preferred embodiment, the at least one protease
inhibitor is therapeutic agent 1, the at least one polymerase
inhibitor is therapeutic agent 2 or therapeutic agent 3, and the at
least one NSSA inhibitor is therapeutic agent 4.

therapeutic agent 4. Therapeutic agent 1 and therapeutic agent 4
can be administered in therapeutically effective amounts to provide
a SVR (for example, a SVR8, SVR12, SVR16, or SVR24) after treatment
duration of no more than 12 weeks, preferably no more than 8 weeks.
The interferon non-responder patients include partial interferon
responders and interferon rebound patients. The interferon
nonresponder patient may have HCV genotype 1, such as 1a. The
interferon nonresponder patient may have HCV genotype 1b. The
interferon nonresponder patient can have HCV genotype 2 or 3, such
as HCV genotype 2a. In some embodiments, the patient may have HCV
genotype 2b. In other embodiments the patient may have HCV genotype

[0161] Accordingly, in some embodiments, the present technology
features a method of treating HCV infection, comprising
administering to a patient in need thereof an effective amount of a
combination of two or more DAAs without ribavirin. The treatment
lasts no more than 12 weeks (e.g., the duration being 12 weeks),
alternatively no more than 11 weeks, alternatively no more than 10
weeks, alternatively no more than 9 weeks, preferably no more than

administration of any interferon or ribavirin. The DAAs can be
administered at the same or different dosing frequencies. The
patient being treated can be an HCV-treatment naive patient or
HCV-treatment experienced patient, including, interferon
non-responders (e.g., null responders), interferon partial
responders (patients whose HCV RNA levels declined but never became
undetectable when treated with interferon), or relapsers (patients
who achieved undetectable levels of HCV RNA during therapy but
rebound) or a patient unable to take interferon. The patient can be
infected with, for example and without limitation, HCV genotypes 1
or 2. In some embodiments are preferably genotypes 1a or 1b. In
other embodiments, the HCV genotype is 2 or 3. Each DAA can be
selected from HCV protease inhibitors, HCV polymerase inhibitors,
or HCV NS5A inhibitors.

[0172] Any HCV inhibitor or DAA described herein encompasses its
suitable salt forms when it is used in therapeutic treatments or
pharmaceutical formulations.
[0173] The following table lists non-limiting examples of the
treatment regimens of the present technology. In each treatment
regimen, the at least two DAA with or without ritonavir, are
administered daily to an HCV patient under such treatment. Each
treatment is interferon-free and ribavirin-free. Each treatment
regimen may also optionally comprise administering one or more
other additional DAAs to the patient. The duration of each
treatment regimen may last, for example and without limitation, no
more than 12 weeks, no more than 11 weeks, no more than 10 weeks,
no more than 9 weeks, no more than 8 weeks, alternatively no more
than 7 weeks, alternatively no more than 6 weeks, alternatively no
more than 5 weeks, alternatively no more than 4 weeks and may
depend on the patient's response. In any given regimen described
below, the drugs can be, for example and without limitation,
co-formulated in a single solid dosage form when each has the same
dosing frequency.
[0174] For instance, two or more drugs used in a regimen can be
co-formulated in amorphous forms or molecularly dispersed in a
matrix comprising a water-soluble polymer and optionally a
surfactant; for another instance, therapeutic agent 1 and ritonavir
(RTV) are formulated in an amorphous form or molecularly dispersed
in a matrix comprising a water-soluble polymer and optionally a
surfactant, and therapeutic agent 3 can be combined with amorphous
Compound 1 and RTV in a single solid dosage form. For yet another
instance, Compound 1 and RTV are formulated in a different dosage
form than that of therapeutic agent 3.

amount of about 125 mg.
[0179] The one or more DAAs can be administered, for example and
without limitation, concurrently or sequentially, and at the same
or different frequencies. For instance, For example, one DAA can be
administered immediately before or after the administration of
another DAA. A short delay or time gap may exist between the
administration of one DAA and that of another DAA. The frequency of
administration may also be different. For example, a first DAA may
be administered once a day and a second DAA may be administered
twice or three times a day. For example, a first DAA with or
without ritonavir may be administered once daily, and a second DAA
may be administered twice daily.
[0180] The DAAs of the present technology can be co-formulated in a
single dosage form. Non-limiting examples of suitable dosage forms
include liquid or solid dosage forms. For example, a dosage form of
Compound 1 as a solid dosage form is described in U.S. Patent
Application Publication No. 2011/0312973, filed Mar. 8, 2011 and
entitled "Solid Compositions", the entire content of which is
incorporated herein by reference. More preferably, the dosage form
is a solid dosage form in which at least one of the DAAs is in an
amorphous form, or highly preferably molecularly dispersed, in a
matrix which comprises a pharmaceutically acceptable water-soluble
polymer and a pharmaceutically acceptable surfactant. The other
DAAs can also be in an amorphous form or molecularly dispersed in
the matrix, or formulated in different form(s) (e.g., in a
crystalline form).
[0181] The DAAs of the present technology can be formulated in
different dosage forms. It will be understood that the total daily
dosage of the compounds and compositions to be administered will be
decided by the attending physician within the scope of sound
medical judgment.

1b HCV Replicon Assay
[0192] Examples 1-3 are for illustration and do not limit the scope
of this disclosure in any way. Not to be bound by any theory, the
unexpected synergistic effects from combining different classes of
HCV inhibitors (e.g., a combination of a protease inhibitor (such
as Compound 1) and a polymerase inhibitor (such as Compound 2), or
a combination of a protease inhibitor (such as Compound 1) and a
NS5A inhibitor (such as Compound 4)) may contribute to the
effectiveness of the short-duration, interferon- and ribavirin-free
therapies of the present technology.
[0193] Materials:
[0194] A replicon cell line was derived from the human hepatoma
cell line Huh7. It was derived from HCV genotype 1b (Con1), and is
a bicistronic subgenomic replicon, essentially similar to those
described in Science 285(5424):110-3 (1999). The first cistron of
the construct contains a firefly luciferase reporter and a neomycin
phosphotransferase selectable marker. Replicon cells were
maintained in Dulbecco's Modified Eagle Media (DMEM) containing 100
IU/ml penicillin, 100 mg/ml streptomycin (Invitrogen), 200 mg/ml
G418, an aminoglycoside antibiotic (Invitrogen) and 10% fetal
bovine serum (FBS) at 37.degree. C. and 5% CO2.
[0195] Replicon Cell Culture:
[0196] Replicon cells were seeded at a density of 5000 cells per
well of a 96-well plate in 100 .mu.l DMEM containing 5% FBS. The
following day, Compounds 1 and 2 were diluted in dimethyl sulfoxide
(DMSO) to generate a 200.times. stock in a series of 6 two-fold
dilutions. The dilution series was then further diluted 100-fold in
the medium containing 5% FBS.
[0197] Combination Studies:
[0198] Combination studies were performed to evaluate the
interaction effects of therapeutic agent 1 and therapeutic agent 2
in the replicon assay described above. The purpose of these studies
was to determine whether there are doses or concentrations of each
compound where synergy or antagonism is demonstrated with the other
compound. Three experiments with three plates in each experiment
were performed on three separate days. Six concentrations of
Compound 1 alone and six concentrations of Compound 2 alone were
assayed in each plate. In addition, 36 combinations of
concentrations of the two compounds were assayed for each plate.
The variable analyzed was the fraction of inhibition of the
luciferase signal.
[0199] The dilutions of each compound were combined with the
dilutions of the other compound in a checkerboard fashion. The
concentrations tested were chosen to ensure that the EC.sub.50 for
each compound alone is in the middle of the serial dilution range.
Medium with inhibitor(s) was added to the cell culture plates
already containing 100 .mu.l of DMEM with 5% FBS. The cells were
incubated in a tissue culture incubator at 37.degree. C. and 5%
CO.sub.2 for three days. The inhibitor effects of compounds on HCV
replication were determined by measuring activity of a luciferase
reporter gene using a Luciferase Assay System kit (Promega)
following the manufacturer's instructions. Passive Lysis buffer (30
.mu.l, Promega) was added to each well, and the plates were
incubated for 15 minutes with rocking to lyse the cells. Luciferin
solution (100 .mu.l, Promega) was added to each well and the
luciferase activity was measured using a Victor II luminometer
(Perkin-Elmer). To determine the EC.sub.50, the luciferase
inhibition data were analyzed using GraphPad Prism 4 software.
Three experiments were performed with three replicates per
experiment. The percent inhibition results were analyzed for
synergy, additivity and antagonism according to the Pritchard and
Shipman model (Antiviral Research 14:181-206 (1990)).
[0200] Combination Analysis:
[0201] Prichard and Shipman proposed a direct approach to solve
this drug-drug interaction problem. The method was able to
calculate theoretical additive effects directly from the individual
dose-response curves determined in the assay. The calculated
theoretical additivity was then compared to the experimental
dose-response surface, and subsequently subtracted to reveal any
areas of aberrant interaction. The following equation was used to
calculate the theoretical additive effects:
Z=X+Y(1-X)=X+Y-XY,
where Z is the total inhibition produced by the combination of
drugs X and Y, with X and Y representing the inhibition produced by
drugs X and Y alone respectively.
[0202] A difference between the actual observed fraction of
inhibition and the predicted value was calculated for each
concentration combination for each plate in each experiment to
determine whether the observed combined effect was greater than the
theoretical additive effect Z calculated from the equation above.
For each concentration combination, the replicates (across all
plates and experiments) were used to calculate a mean difference
between observed and predicted fraction of inhibition, its standard
error and its two-sided 95% confidence interval.
[0203] Synergy or antagonism for a concentration combination was
determined based on the following 2 rules: First, the 95% CI of the
mean difference between observed and predicted fraction of
inhibition at each concentration combination is calculated. If the
lower bound of 95% CI is larger than zero, then the drug
combination would be considered having a synergistic effect; if the
upper bound of 95% CI is less than zero, then the drug combination
would be considered having an antagonistic effect; otherwise, no
significant antagonism or synergy at this concentration
combination.
[0204] Second, the synergistic or antagonistic effect must have its
relative mean difference, the absolute mean difference divided by
its corresponding observed mean inhibition, greater than 1%. By
doing this, small differences of statistical significance caused by
very small variance could be excluded.
[0205] Combination of Therapeutic Agent 1 and Therapeutic Agent
2:
[0206] The inhibitory effects on replicons produced by each drug
alone or in combination with the other at concentrations up to
ten-fold above the EC.sub.50 were examined in the genotype 1b
(Con1) replicon using a checkerboard titration pattern (two-fold
serial dilutions) in a standard three-day antiviral assay. The
concentrations tested were chosen to ensure that the EC.sub.50
values of the compounds were in the middle of the serial dilution
range. For Compound 1, concentrations ranged from 0.031 nM to 1.0
nM. For Compound 2, concentrations ranged from 0.125 nM to 4.0 nM.
Synergy, additivity, and antagonism were evaluated using the
Pritchard and Shipman model.
[0207] Results:
[0208] The results of the assay analysis are illustrated in FIGS. 1
and 2 and Table 2. In the 3-D surface plot of FIG. 1, deviations
from expected interactions between Compound 1 and Compound 2 are
purely additive at concentrations associated with a horizontal
plane at 0%. Synergistic interactions between Compound 1 and
Compound 2 appear as a peak above the horizontal plane with a
height corresponding to the percent above calculated additivity.
Antagonistic interactions between Compound 1 and Compound 2 appear
as a pit or trough below the horizontal plane with a negative value
signifying the percent below the calculated additivity. Synergistic
interactions appear as dark grey, additive interactions appear
white, and antagonistic interactions appear as speckled.
[0209] As illustrated in the 3-D surface plot of FIG. 1 and the
contour plot of FIG. 2, an additive or synergistic effect exists at
most of the concentrations for Compound 1 and Compound 2. In
particular, there is a concentration region showing synergy at most
concentrations of Compound 1 and at the lower to mid-range dose
concentrations of Compound 2.
[0210] Table 2 below lists combinations of concentrations of
Compound 1 and Compound 2 with statistically significant
synergistic or antagonistic effects based on the Prichard and
Shipman model analysis. For each combination of concentrations,
Table 2 includes the mean difference in the observed and predicted
fraction of inhibition, the standard deviation or error of the mean
difference, and the upper and lower limits of the 95% confidence
interval.
[0211] According to Table 2, all of the combinations of Compound 1
and Compound 2 listed in the table have statistically significant
synergistic effects.
[0212] The results presented in FIGS. 1 and 2 and Table 2
demonstrate that the combination of therapeutic agent 1 and
therapeutic agent 2 achieves additivity or synergy at most of the
concentration combinations of the two agents. Taken together, these
in vitro replicon results suggest that therapeutic agent 2 should
produce a significant antiviral effect in patients when
administered in combination with therapeutic agent 1 in patients
infected with HCV.

Example 2
Synergistic Concentrations of Compound 1 and Compound 4 in Genotype
1b HCV Replicon Assay
[0213] Materials: The replicon cell line was derived from the human
hepatoma cell line Huh7. It was derived from HCV genotype 1b
(Con1), and is a bicistronic subgenomic replicon, essentially
similar to those described in Science 285(5424):110-3 (1999). The
first cistron of the construct contains a firefly luciferase
reporter and a neomycin phosphotransferase selectable marker.
Replicon cells were maintained in Dulbecco's Modified Eagle Media
(DMEM) containing 100 IU/ml penicillin, 100 mg/ml streptomycin
(Invitrogen), 200 mg/ml G418 (Invitrogen) and 10% fetal bovine
serum (FBS) at 37.degree. C. and 5% CO.sub.2.
[0214] Replicon Cell Culture:
[0215] Replicon cells were seeded at a density of 5000 cells per
well of a 96-well plate in 100 .mu.l DMEM containing 5% FBS. The
following day, compounds were diluted in dimethyl sulfoxide (DMSO)
to generate a 200.times. stock in a series of 6 two-fold dilutions.
The dilution series was then further diluted 100-fold in the medium
containing 5% FBS.
[0216] Combination Studies:
[0217] Combination studies were performed to evaluate the
interaction effects of therapeutic agent 1 and therapeutic agent 4
in the replicon assay described above. The purpose of these studies
was to determine doses or concentrations of each compound where
synergy or antagonism is demonstrated with the other compound.
Three experiments with three plates in each experiment were
performed on three separate days. Six concentrations of Compound 1
alone and six concentrations of Compound 2 alone were assayed in
each plate. In addition, 36 combinations of concentrations of the
two compounds were assayed for each plate. The variable analyzed
was the fraction of inhibition of the luciferase signal.
[0218] The dilutions of each compound were combined with the
dilutions of the other compound in a checkerboard fashion. The
concentrations tested were chosen to ensure that the EC.sub.50 for
each compound alone is in the middle of the serial dilution range.
Medium with inhibitor(s) was added to the cell culture plates
already containing 100 .mu.l of DMEM with 5% FBS. The cells were
incubated in a tissue culture incubator at 37.degree. C. and 5%
CO.sub.2 for three days. The inhibitor effects of compounds on HCV
replication were determined by measuring activity of a luciferase
reporter gene using a Luciferase Assay System kit (Promega)
following the manufacturer's instructions. Passive Lysis buffer (30
.mu.l, Promega) was added to each well, and the plates were
incubated for 15 minutes with rocking to lyse the cells. Luciferin
solution (100 .mu.l, Promega) was added to each well and the
luciferase activity was measured using a Victor II luminometer
(Perkin-Elmer). To determine the EC.sub.50, the luciferase
inhibition data were analyzed using GraphPad Prism 4 software.
Three experiments were performed with three replicates per
experiment. The percent inhibition results were analyzed for
synergy, additivity and antagonism according to the Pritchard and
Shipman model (Antiviral Research 14:181-206 (1990)).
[0219] Combination Analysis:
[0220] The Prichard and Shipman approach to calculating theoretical
additive effects (described in Example 1) was used for the present
example.
[0221] The difference between the actual observed fraction of
inhibition and the predicted value was calculated for each
concentration combination for each plate in each experiment to
determine whether the observed combined effect was greater than the
theoretical additive effect Z calculated from the Prichard and
Shipman equation. For each concentration combination, the
replicates (across all plates and experiments) were used to
calculate a mean difference between observed and predicted fraction
of inhibition, its standard error and its two-sided 95% confidence
interval.
[0222] Synergy or antagonism for a concentration combination was
determined based on the same rules set forth in Example 1.
[0223] Combination of Therapeutic Agent 1 and Therapeutic Agent 4:
The inhibitory effects in replicon produced by each drug alone or
in combination with the other at concentrations up to ten-fold
above the EC.sub.50 were examined in the genotype 1b (Con1)
replicon using a checkerboard titration pattern (two-fold serial
dilutions) in the standard three-day antiviral assay. The
concentrations tested were chosen to ensure that the EC.sub.50
values of the compounds were in the middle of the serial dilution
range. For Compound 4, concentrations ranged from 0.0002 nM to
0.0063 nM, and for Compound 1, concentrations ranged from 0.023 nM
to 0.75 nM. Synergy, additivity, and antagonism were evaluated
using the Pritchard and Shipman model.
[0224] Results:
[0225] The results of the assay analysis are illustrated in FIGS. 3
and 4 and Table 3. In the 3-D surface plot of FIG. 3, deviations
from expected interactions between Compound 1 and Compound 4 are
purely additive at concentrations associated with a horizontal
plane at 0%. Synergistic interactions between Compound 1 and
Compound 4 appear as a peak above the horizontal plane with a
height corresponding to the percent above calculated additivity.
Antagonistic interactions between Compound 1 and Compound 4 appear
as a pit or trough below the horizontal plane with a negative value
signifying the percent below the calculated additivity. Synergistic
interactions appear as shades of dark grey, additive interactions
appear white, and antagonistic interactions appear as speckled.
[0226] As illustrated in the 3-D surface plot of FIG. 3 and the
contour plot of FIG. 4, an additive or synergistic effect exists at
most of the concentrations for Compound 1 and Compound 4. In
particular, there is a concentration region showing synergy at the
lower dose concentrations of Compound 4 and mid-range dose
concentrations of Compound 1.
[0227] Table 3 below lists combinations of concentrations of
Compound 1 and Compound 4 with statistically significant
synergistic or antagonistic effects based on the Prichard and
Shipman Model analysis. For each combination of concentrations,
Table 3 includes the mean difference in the observed and predicted
fraction of inhibition, the standard deviation or error of the mean
difference, and the upper and lower limits of the 95% confidence
interval.
[0228] According to Table 3, most of the combinations of Compound 1
and Compound 4 listed in the table have statistically significant
synergistic effects. A small amount of antagonism was observed at
the lowest concentrations of Compound 1.
[0229] The results presented in FIGS. 3 and 4 and Table 3
demonstrate that the combination of therapeutic agent 4 and
therapeutic agent 1 achieves additivity at most of the
concentration combinations of the two agents and achieves synergy
at certain concentration combinations, in particular, at low
concentrations of therapeutic agent 4 and mid-range concentrations
of therapeutic agent 1. Taken together, these in vitro replicon
results suggest that therapeutic agent 4 should produce a
significant antiviral effect in patients when administered in
combination with therapeutic agent 1 in patients infected with
HCV.

[0230] Similar results were also demonstrated for the combination
of therapeutic agent 2 and therapeutic agent 4, where additivity
was observed at most of the concentration combinations of the two
agents and synergy was observed at low concentrations of
therapeutic agent 2 and therapeutic agent 4.
Example 3
Reduction of HCV-Infected Cells with Combinations of Therapeutic
Agents 1, 2 and 4
[0231] In order to quantify the frequency of resistant replicon
colonies selected by therapeutic agent 1, therapeutic agent 2,
therapeutic agent 4, or various combinations of these agents, the
stable subgenomic replicon cell line derived from HCV genotype 1a
(H77; Genbank accession number AF011751) was utilized. The replicon
construct was bicistronic and the cell line was generated by
introducing the constructs into cell lines derived from the human
hepatoma cell line Huh-7. The replicon also has a firefly
luciferase reporter and a neomycin phosphotransferase (Neo)
selectable marker. The two coding regions, separated by the FMDV 2a
protease, comprise the first cistron of the bicistronic replicon
construct, with the second cistron containing the HCV NS3-NS5B
coding region with addition of adaptive mutations E1202G, K1691R,
K2040R and S2204I. This HCV replicon cell line was maintained in
Dulbecco's modified Eagles medium (DMEM; Invitrogen) containing 10%
(v/v) fetal bovine serum, 100 IU/ml penicillin, 100 .mu.g/ml
streptomycin, and 200 .mu.g/ml G418 (all from Invitrogen). 1a-H77
replicon cells (10.sup.5-10.sup.6) were plated in 150 mm cell
culture plates and grown in the presence of G418 (400 .mu.g/ml) and
Compound 1, Compound 2, and/or Compound 4 at concentrations that
were either 10-fold (10.times.) or 100-fold (100.times.) above the
EC.sub.50 value for the HCV genotype 1a replicon cell line. The
EC.sub.50 values for Compound 1, Compound 2, and Compound 4 used
for this experiment were 0.9, 7.7, and 0.01 nM, respectively. After
three weeks of treatment, the majority of replicon cells were
cleared of replicon RNA and, therefore, were unable to survive in
the G418-containing medium since the replicon RNA included the neo
marker conferring G418 resistance. The cells containing resistant
replicon variants survived and formed colonies, and these colonies
were stained with 1% crystal violet in 10% Protocol SafeFix II
reagent (Fisher Scientific), and counted. As shown in FIG. 5A, the
combination of Compound 4 plus either Compound 1 or Compound 2 at
either 10-fold or 100-fold above their respective EC.sub.50 value
resulted in significantly fewer colonies than either Compound 1,
Compound 2, or Compound 4 alone at 10-fold or 100-fold above their
respective EC.sub.50 value.
[0232] FIG. 5B illustrates the percentage of colonies surviving two
vs. three DAA combinations. In colony survival assays, 1a-H77
replicon cells were grown in the presence of a DAA combination and
G418 for approximately three weeks, after which time the cells
containing resistant replicon variants had formed colonies. The
cells were stained with crystal violet and counted. "Triple
Combination" is either a combination of Compounds 1, 2 and 4 at
concentrations of 5-fold (5.times.) over their respective EC50
values, or a combination of Compounds 1, 2 and 4 at concentrations
of 10-fold (10.times.) over their respective EC50 values.
[0233] FIGS. 5C and 5D show the effect of a combination of
Compounds 1 and 4 in long-term HCV RNA reduction assays in genotype
1 replicon cell lines. In long-term replicon RNA reduction assays,
106 replicon cells were plated in the absence of G418. The
inhibitors at concentrations of either 10-fold (10.times.) or
100-fold (100.times.) over their respective EC50 values were added,
and the cells were grown to approximately 95% confluence (4 days).
At each passage, 106 cells were removed and frozen, and an
additional 106 cells were passed into another flask with fresh
media and inhibitors. RNA was extracted from 106 cells and HCV RNA
was measured in a Real-Time RT-PCR assay. FIGS. 5C and 5D show that
in both 1a and 1b replicon cells, the combination of Compounds 1
and 4, each at 10-fold over EC50, is more effective at clearing
cells of replicon than 100-fold over EC50 of either inhibitor
alone.
[0234] Predominant resistant variants selected by Compound 1, 2, or
4 in genotype 1 replicons were also determined. For Compound 1, the
predominant resistance variants in 1a-H77 replicons include R155K,
D168A and D168V with fold resistance of 26, 48 and 128,
respectively; and the predominant resistance variants in 1b-Con1
replicons include R155K, A156T and D168V with fold resistance of
48, 9 and 190, respectively. For Compound 2, the predominant
resistance variants in 1a-H77 replicons include C316Y, M414T, Y448C
and S556G with fold resistance of 1600, 36, 980 and 15,
respectively; and the predominant resistance variants in 1b-Con1
replicons include C316Y, M414T and D559G with fold resistance of
1400, 26 and 100, respectively. For Compound 4, the predominant
resistance variants in 1a-H77 replicons include M28T, M28V, Q30R,
Y93C and Y93H with fold resistance of 9000, 60, 800, 1700 and
41000, respectively; and the predominant resistance variants in
1b-Con1 replicons include Y93H with fold resistance of 55. These
experiments also showed that in genotype 1a, a number of variants
selected by Compounds 2 or 4 conferred higher levels of resistance
than those selected by Compound 1, and that in genotype 1b, one
variant (C316Y) selected by Compound 2 conferred a higher level of
resistance than those selected by either Compound 1 or Compound
4.
[0235] The above examples show that the combination of two
different classes of DAAs (e.g., a combination of a HCV protease
inhibitor and a HCV polymerase inhibitor, or a combination of a HCV
protease inhibitor and a HCV NS5A inhibitor, or a combination of a
HCV polymerase inhibitor and a HCV NS5A inhibitor) can lead to an
improved resistance barrier in patients relative to a single DAA
alone, while the combination of three different classes of DAAs
(e.g., a combination of a HCV protease inhibitor, a HCV polymerase
inhibitor, and a HCV NS5A inhibitor) can lead to even more
significant barrier to resistance. Improvement in the barrier to
resistance achieved through co-administration of multiple DAAs of
different classes or with different mechanism of action is expected
to correlate with enhanced efficacy in patients.
Example 4
Use of 2-DAA Combination without Interferon and Ribavirin to Treat
Treatment-Naive Subjects Infected with Genotype 1, 2 or 3
Genotype 1
[0236] Ten previously untreated subjects infected with HCV genotype
1 were treated with a 2-DAA combination for 12 weeks. The treatment
was interferon- and ribavirin-free and was designed to last for 12
weeks. The 2-DAA combination included Compound 1/r (200/100 mg QD)
and Compound 4 (25 mg QD). At week 3 the treatment, seven of the
ten subjects showed no detectable HCV RNA; and the remaining three
subjects had HCV RNA levels of less than 25 IU/mL. At week 4, eight
subjects showed no detectable HCV RNA, and the remaining two showed
(or were believed to have) an HCV RNA level of less than 25 IU/mL.
At week 5, nine subjects had no detectable HCV RNA and the
remaining one had an HCV RNA level of less than 25 IU/mL. At weeks
6 and 7 of the treatment, all ten subjects were tested and found no
detectable HCV RNA. At weeks 9, 10, 11 and 12 of the treatment, one
subject showed viral rebound (breakthrough), and the remaining nine
subjects showed no detectable HCV RNA.
[0237] At post-treatment week 2, at least seven subjects were
tested and found no detectable HCV RNA. At post-treatment week 4,
at least seven subjects were tested and found no detectable HCV
RNA. At post-treatment week 8, at least three subjects were tested
and found no detectable HCV RNA.
Genotype 2
[0238] Ten previously untreated subjects infected with HCV genotype
2 were treated with the same regimen of this Example. At week 3 of
the treatment, eight of the ten subjects showed no detectable HCV
RNA, one had viral rebound, and one had HCV RNA levels of less than
25 IU/mL. At week 5 of the treatment, nine of the ten subjects
showed no detectable HCV RNA, and one had breakthrough. At weeks
10, 11 and 12 of the treatment, at least seven of the ten subjects
were tested and found no detectable HCV RNA.
[0239] At post-treatment week 2, at least five subjects found no
detectable HCV RNA; and two more subjects had breakthrough. At
post-treatment week 4, at least four subjects found no detectable
HCV RNA.
Genotype 3
[0240] Similarly, ten previously untreated subjects infected with
HCV genotype 3 were treated with the same regimen of this Example.
At weeks 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 of the treatment, two
subjects showed no detectable HCV RNA. At post-treatment weeks 2
and 4, the same two subjects were confirmed with no detectable HCV
RNA. A number of subjects appeared to have breakthrough during the
treatment.
Example 5
Use of 3-DAA Combination without Interferon and Ribavirin to Treat
Treatment-Naive Subjects Infected with Genotype 1
[0241] Twelve previously untreated subjects with HCV genotype 1
infection were treated with a 3-DAA combination for 12 weeks. The
treatment was interferon- and ribavirin-free. The 3-DAA combination
included Compound 1/r (150/100 mg QD), Compound 2 (400 mg BID), and
Compound 4 (25 mg QD). The weight based dosing of ribavirin ranged
from 1000 to 1200 mg divided twice daily.
[0242] At week 3 of the treatment, seven of the twelve subjects had
no detectable HCV RNA, and the five remaining subjects had HCV RNA
levels of less than 25 IU/mL. At week 4 of the treatment, nine of
the twelve subjects had no detectable HCV RNA, and the three
remaining subjects had HCV RNA levels of less than 25 IU/mL. At
weeks 6 and 8, all twelve subjects had no detectable HCV RNA. At
weeks 10 and 12, eleven of the twelve subjects showed no detectable
HCV RNA, and one subject had detectable HCV RNA.
[0243] At post-treatment weeks 2 and 4, at least ten of the twelve
subjects were tested and found no detectable HCV RNA. At
post-treatment week 8, at least seven of the twelve subjects were
tested and found no detectable HCV RNA. Two subjects appeared to
have breakthrough during or after the treatment.
Example 6
Clinical Modeling for Interferon-Free DAA Combination Therapies
[0244] This example describes a novel clinical model for evaluating
optimal doses and durations of interferon-free HCV therapies using
combinations of different DAAs. This model reasonably predicted the
effectiveness of numerous DAA combinations in interferon-free,
short-duration therapies.
[0245] A mechanistic model was used to model the relationship
between DAA exposures and antiviral efficacy in HCV-infected
subjects. This model was used to conduct clinical trial simulations
of clinical outcomes following administration of various DAA
combination regimens (e.g., specific DAA combinations and different
doses of DAAs) and durations of therapy.
[0246] Numerous DAAs have been extensively documented to select
mutants following short duration of monotherapy (e.g., less than 1
week). The viral dynamic model of this Example included single and
double mutants. Specifically, the model included 2 single mutants
and one double mutant for each of the 2-DAA combination regimens.
Thus, a 2-DAA combination regimen (e.g., a combination of a
protease inhibitor and a NS5A inhibitor) included 2 single mutants
and one double mutant. A 3-DAA combination (e.g., a combination of
a protease inhibitor, a polymerase inhibitor and a NS5A inhibitor,
such as a combination of a protease inhibitor, a non-nucleoside
polymerase inhibitor (NNPI) and a NS5A inhibitor) included 3 single
and 2 double mutants.
[0247] The model has 3 components: hepatocytes (uninfected or
target cell), infected cell and viral dynamics. The differential
equations describing the dynamics of the 3 components are as
follows:

[0264] As shown in the differential equations for viral dynamics,
the effect of DAA is included as an inhibition of viral load
production. For example, the effect of DAA(s) on production of wild
type virus is given as (1-Eff1)*.rho. where Eff1 is the fraction of
viral production that is inhibited. In the absence of drug Eff1=0
and in the presence of drug Eff1 takes a value between 0 and 1.
Eff1 is described using an Emax model:
Eff1=Emax*Conc/(EC.sub.50+Conc)
where Emax represents maximum inhibition, Conc is the plasma DAA
concentration and EC.sub.50 is the concentration that inhibits
viral load production by 50%. As the fold-change in EC.sub.50 for
the mutants compared to wild type virus was based on values
obtained from in vitro replicon studies, EC.sub.50 was estimated
only for wild type virus.
[0265] For DAA combinations, the effect was assumed to be
multiplicative and incorporated as follows:
(1-Eff1)=(1-Eff.sub.DAA1)*(1-Eff.sub.DAA2)*(1-Eff.sub.DAA3)
[0266] The effect of ribavirin (RBV) can also be added on infection
rate .beta. as an Emax model. In presence of ribavirin, the
infection rate decreases by a factor (1-.eta.) where
.eta.=Conc.sub.RBV/(EC.sub.50-RBV+Conc.sub.RBV)
[0267] The model does not include a double mutant to the
polymerase+NS5A inhibitors. In a 3-DAA regimens, a polymerase+NS5A
double mutant is often wild type for the protease inhibitor. Hence,
this double mutant is not expected to significantly affect clinical
outcomes for a 3-DAA regimen simulation. On the other hand, the
model can be readily adapted to simulate a 2-DAA regimen containing
a polymerase inhibitor and a NS5A inhibitor by treating the
polymerase inhibitor (e.g., PSI-7977) as a protease inhibitor in
the model.
[0268] The lowest available limit of detection (LOD) of viral load
assays is 10 IU/mL. Assuming 3 virion particles per IU, this
constitutes about 0.5 million viruses in the body at LOD. Hence,
subjects have to be treated for significant period of time after
their viral load falls below the LOD to achieve cure. This duration
depends on the potency of the compounds and the individual response
to therapy.
[0269] In order to predict the duration required for cure, a
"threshold" concept was used. For simulations, an HCV-infected
subject was assumed to achieve SVR when viral load reaches less
than 1 virion in the total plasma and extracellular fluid volume
(about 15000 mL), i.e., viral load measurement of <1 copy/15000
mL or <0.33 IU/15000 mL. This translates to about 5 log IU/mL.
Cf. Snoeck E et al., CLIN PHARMACOL THER. 87(6):706-13 (2010),
wherein based on data from patients treated with peg-IFN and
ribavirin, subjects were estimated to achieve SVR when the
predicted number of infected cells fell below 1. While such low
viral loads cannot be measured experimentally, they can be
simulated using the viral dynamic model.
[0270] The model can be used to predict SVR for any combination of
DAAs, with or without interferon, and with or without
ribavirin.
[0271] As non-limiting examples, various interferon-free treatment
regimens using different combinations of Compound 1, Compound 2
and/or Compound 4, with or without ribavirin, were evaluated using
the model of this Example. The following approach was used to
include mutants in the model: [0272] a. One single mutant per DAA
[0273] b. One double mutant per DAA combination
[0274] For a combination of two DAAs, e.g., a combination of
Compound 1 and Compound 2, the model included one mutant resistant
to Compound 1, one mutant resistant to Compound 2, and one double
mutant resistant to both Compound 1 and Compound 2. Compound 1 is
coadministered or co-formulated with ritonavir (or another
pharmacokinetics enhancer) to improve its drug exposure.
[0275] A double mutant to Compound 2 and Compound 4 was not
included in the modeling. In the 3-DAA regimens, a Compound
2/Compound 4 double mutant is likely wild type for Compound 1 due
to the high potency and resistant profile of Compound 1. Hence, the
Compound 2/Compound 4 double mutant is not expected to affect
clinical outcomes for treatments containing Compound 1.
[0276] Single mutants included in the model were based on mutants
observed for the individual DAAs in the Phase 1b and 2a studies
(e.g., clinical studies M10-351, M12-116, and M11-602). For double
mutants with resistance to 2 DAA classes, the sensitivity
(EC.sub.50) of double mutants to drug was assumed to be a
combination of the 2 single mutants. Thus, for Compound 1 and
Compound 2, the single mutants were D168V and M414T, respectively,
and the double mutant was D168V-M414T. In this scenario, the D168V
mutant would be less sensitive to Compound 1 but would be as
sensitive to Compound 2 as wild type virus. Similarly, the M414T
mutant would be less sensitive to Compound 2 but would be as
sensitive to Compound 1 as wild type virus. The double mutant
D168V-M414T would be less sensitive to both Compound 1 and Compound
2.
[0277] The fold change in EC.sub.50 for the mutants compared to
wild type virus was based on values obtained from in vitro replicon
studies. Since monotherapy data for Compound 4 indicated a variety
of mutants with different EC.sub.50s, a value of 1000.times. fold
change in EC.sub.50 was used for Compound 4 for modeling and
simulations.
[0278] Baseline prevalence of the mutants was estimated during
model fitting, while the mutation rate was based on the literature
values. Both baseline prevalence and mutation rate determined
mutant fitness.
[0279] Pharmacokinetic data and viral load data from 140
treatment-naive HCV-infected subjects were used to construct the
model. For modeling, number of target cells at baseline, number of
infected cells at baseline, death rate of target cells and mutation
rates were based on literature values. See, e.g., Snoeck et al.

al. ANTIVIR THER. 13(7):919-26 (2008); and Dahari et al. J THEOR
BIOL. 247(2):371-81 (2007). The production rate of virus and
infection rate of virus were derived from other parameters in the
model. All other parameters were estimated. Exposure-antiviral
response modeling was performed using NONMEM 7.2.
[0280] Clinical trial simulations were performed using Trial
Simulator version 2.2.1. Fifty subjects and 50 replicates were
simulated for each treatment. A subject drop out rate from the
study due to any reason was assumed to be 8% over 24 weeks based on
available literature on trials in subjects with HCV. All
simulations were conducted assuming 100% compliance. Covariates
included in the simulations were genotype 1a/1b status. Clinical
outcomes simulated included: (1) percentage of subjects below limit
of detection (LOD) of 10 IU/mL and (2) percentage of subjects
achieving SVR.
[0281] Clinical trial simulations were conducted to determine
optimal dose and duration for SVR. Over 80 scenarios were simulated
to predict the percentage of subjects with SVR following
administration of various 2- and 3-DAA combinations (e.g., Compound
1+Compound 2, or Compound 1+Compound 4, or Compound 1+Compound
2+Compound 4), without RBV, at a range of doses for each DAA (e.g.,
Compound 1/ritonavir at 250/100, 150/100 or 100/100 mg QD, Compound
4 at 5, 25 or 100 mg QD, and Compound 2 at 400 or 800 mg BID) and
across a range of treatment durations (e.g., 2. 4, 6, 8, 10, 12,
16, and 24 weeks).
[0282] Optimal dose and duration were predicted based on percentage
of subjects with viral load of less than -5 log IU/mL threshold for
SVR. Selected and relevant results of simulation for the 2- and
3-DAA combinations of Compounds 1, 2 and/or 4 are shown in FIGS.
6A, 6B and 6C for two different doses of Compound 1. FIG. 6A shows
the predicted median SVR percentage ("% SVR") and 90% confidence
interval (the vertical bar at the top of each SVR percentage
column) for different treatment durations using a combination of
Compound 1 and Compound 2; FIG. 6B shows the predicted median and
90% confidence interval for different treatment durations using a
combination of Compound 1 and Compound 4; and FIG. 6C shows the
predicted median and 90% confidence interval for different
treatment durations using a combination of Compound 1, Compound 2
and Compound 4. In each simulation, RBV was included, and Compound
1 was used with 100 mg ritonavir, and the subjects are HCV genotype
1, treatment-naive patients. SVR24 is lower than SVR12 in some
cases due to drop out; longer durations are not necessarily
predicted to improve SVR but could result in more dropouts
resulting in lower SVR.
[0283] The model predicted that with 8-12 weeks of dosing at least
80 to 90% subjects can achieve SVR with 2 and 3 DAA combinations.
The model also predicted that durations shorter than 8 weeks can
cure a significant number of subjects. A 2-DAA regimen was
predicted to cure over 40% of the subjects and a 3-DAA regimen was
predicted to cure about 60% of the subjects with only 6 weeks of
dosing. Dosing for durations of over 12 weeks was not expected to
increase the percentage of subjects with SVR significantly.
Addition of the 3.sup.rd DAA was predicted to shorten treatment
duration by 2 to 4 weeks as optimal durations for the 3-DAA
combination of Compound 1, Compound 2 and Compound 4 were predicted
to be 8-10 weeks.
[0284] FIGS. 6A, 6B and 6C illustrate the predictions for DAA
combinations without ribavirin.
[0285] The model also predicts similar or comparable SVR
percentages for these DAA combinations when used with ribavirin. In
addition, the effect of interferon (e.g., pegylated interferon) can
also be added by incorporating interferon similar to a DAA but
without any resistant mutants.
[0286] One of the advantages that the model provides is that it
allows examination of various viral parameters and its effect on
dose, duration and SVR. For example while experimentally
determining the effect of mutants parameters is very difficult if
not impossible, they can be examined using the model. Thus SVR in
patient population that have different mutants can be predicted
with the model.
[0287] The model was used to simulate a treatment regimen which
included 150/100 mg Compound 1/ritonavir QD+400 mg Compound 3
QD+weight-based amounts of RBV BID for 12 weeks. Subjects under the
treatment included 11 treatment naive subjects between the ages of
18 and 65. All subjects completed 12 weeks of therapy with Compound
1 and ritonavir (Compound 1/r) dosed in combination with Compound 3
and ribavirin (RBV). Compound 1 (150 mg once daily (QD)) was dosed
with 100 mg QD ritonavir, 400 mg QD Compound 3, and weight-based
amounts of RBV in treatment naive subjects infected with genotype
(GT) 1 HCV. The percentage of subjects with HCV RNA less than LOD
at 2, 4, 8, 10, and 12 weeks was summarized in FIG. 7. The mean
predicted versus observed percentage of subjects with below LOD ("%
LOD") at respective weeks are shown FIG. 7. 95% confidence
intervals for the predicted data (the vertical bar at the top of
each respective predicted LOD percentage column) were also
indicated. As shown in FIG. 7, the model reasonably predicted the
clinical outcome of % LOD.
[0288] The model was also used to simulate another treatment
regimen. The regimen included three groups of patients. In Group 1,
previously untreated subjects having HCV infection were treated
with a protease inhibitor (in combination with ritonavir), a
polymerase inhibitor, and ribavirin. The treatment was without
interferon. Subjects included 19 treatment naive subjects between
the ages of 18 and 65. One subject discontinued the study at week
3. All of the remaining 18 subjects completed 12 weeks of therapy
with Compound 1/r dosed in combination with Compound 2 and RBV.
Compound 1 (250 mg QD) was dosed with 100 mg QD ritonavir, 400 mg
BID Compound 2, and RBV in treatment naive subjects infected with
GT1 HCV.
[0289] In Group 2, previously untreated subjects having HCV
infection were treated with a protease inhibitor (in combination
with ritonavir), a polymerase inhibitor, and ribavirin. The
treatment was without interferon. Subjects included 14 treatment
naive subjects between the ages of 18 and 65. One subject
discontinued the study at week 1. Therefore, a total of 13 subjects
were under study. All of the thirteen subjects completed 12 weeks
of therapy with Compound 1/r dosed in combination with Compound 2
and RBV. Compound 1 (150 mg QD) was dosed with 100 mg QD ritonavir,
400 mg BID Compound 2, and RBV in treatment naive subjects infected
with GT1 HCV.
[0290] In Group 3, peginterferon+ribavirin (P/RBV) non-responders
were treated with a protease inhibitor (in combination with
ritonavir), a polymerase inhibitor, and ribavirin. The treatment
was without interferon. Subjects included 17 P/RBV non-responders
between the ages of 18 and 65. Subjects were treated with Compound
1/r dosed in combination with Compound 2 and RBV for 12 weeks.
Compound 1 (150 mg QD) was dosed with 100 mg QD ritonavir, 400 mg
BID Compound 2, and RBV in P/RBV non-responders infected with GT1
HCV. During the treatment, four patients had breakthroughs and
discontinued the study before week 7.
[0291] The mean predicted versus observed percentage SVR ("% SVR")
after 12-week treatment are shown FIG. 8. 95% confidence intervals
for the predicted data (the vertical bar at the top of each
respective predicted SVR percentage column) were also indicated. As
shown in FIG. 8, the predicted SVR percentages aligned well with
the observed SVR percentages. Simulations also predict that the
same treatment regimen but without ribavirin has similar or
comparable LOD percentages for different treatment durations.
[0292] The exposure response viral dynamic model of this Example
provided a quantitative method to reasonably predict SVR for
various combination of antiviral compounds. Based on the
exposure-antiviral response modeling and clinical trial
simulations, it demonstrated that (1) addition of a 3.sup.rd DAA to
a 2-DAA combination can reduce optimal duration of treatment and/or
increase SVR; (2) 8-12 weeks of dosing is the optimal duration of
therapy for 2 and 3 DAA combinations of Compound 1/r, Compound 2
and Compound 4; and (3) durations shorter than 8 weeks of
interferon-free treatment have been predicted to cure a significant
percent of the subjects.
Example 7
Clinical Modeling for Interferon-Free DAA Combination Therapies
Containing BMS-790052 and BMS-650032
[0293] The model described above was also used to predict the SVR
percentage of interferon-free treatment regimens containing
BMS-790052 and BMS-650032 without ribavirin, based on existing
published clinical data including two Phase 1 and one Phase 2 study
of BMS-790052 and one Phase 1 and one Phase 2a study of BMS-650032.
FIG. 9 shows the predicted median SVR percentage and 90% SVR
confidence interval for different treatment durations of a 2-DAA
regimen containing BMS-790052 (60 mg QD) and BMS-650032 (600 BID)
in genotype 1 naive subjects. The combination of BMS-790052 (60 mg
QD) plus BMS-650032 (600 mg BID) in genotype 1 subjects was
predicted to achieve improved SVR for durations of 12 weeks or
greater with predicted SVR rates of about 70% for 10 weeks of
dosing. Similar regimens but containing ribavirin, or regimens with
similar dosings of BMS-790052 and BMS-650032 with or without
ribavirin, are expected to achieve similar SVR rates.
Example 8
Clinical Modeling for Interferon-Free Therapies Containing
PSI-7977
[0294] Likewise, a 3-DAA regimen without interferon and ribavirin
was modeled for genotype 1 patients based on existing clinical
data. The 3-DAA regimen contains 200/100 mg QD Compound 1/r, 50 mg
QD Compound 4, and 400 mg QD PSI-7977. FIG. 10 depicts the
predicted median SVR rates for different treatment durations of
this 3-DAA combination. This 3-DAA combination was predicted to
have over 60% SVR in 6 weeks and over 80% SVR at duration of
8-week, 10-week, 12-week or longer treatment. Similar regimens but
containing ribavirin, or regimens with similar dosings of Compound
1/r, Compound 4 and PSI-7977 with or without ribavirin, are
expected to achieve similar SVR rates.
[0295] The model can also be used to predict SVR for regimens
containing single DAA or single DAA with ribavirin. For example,
the model predictions for PSI-7977+ribavirin for various durations
for treating HCV genotype 1 treatment-naive patients were obtained.
FIG. 11 depicts the predicted median and 90% confidence interval of
SVR percentage for different treatment durations of such a regimen
containing PSI-7977 (as the sole DAA; 400 mg QD) and ribavirin (600
mg BID). The 90% confidence interval for the predicted SVR (the
vertical bar at the top of each respective predicted SVR percentage
column) is also indicated in FIG. 11. The prediction was based on
the already published clinical data for PSI-7977. SVR rate for
PSI-7977+ribavirin was predicted to be around 75-90% following 12
weeks of dosing, and about 55-75% following 8 weeks dosing, in
genotype 1 subjects. Similar SVR percentages for genotype 1
treatment-naive patients are expected for similar regimens
containing similar PSI-7977 QD dosing (e.g., 200-600 mg QD) but
without ribavirin.
[0296] Data from two Phase 1 and one Phase 2 study of Daclatasvir
(BMS-790052) and one Phase 1 and one Phase 2 study of PSI-7977 were
used for estimating the pharmacokinetic and viral dynamic model
parameters. Predictions for a 2-DAA combination with Daclatasvir
(BMS-790052) and PSI-7977 in genotype 1 naive patients are shown in
FIG. 12. The model predicted that following 10-12 weeks of dosing
with the combination of Daclatasvir and PSI-7977 without ribavirin,
at least 90% of HCV genotype 1 naive patients can achieve SVR.
[0297] Similarly, data from one Phase 1a study of TMC-435 and one
Phase 1 and one Phase 2 study of PSI-7977 were used for estimating
the pharmacokinetic and viral dynamic model parameters. Predictions
for a 2-DAA combination with the TMC-435 and PSI-7977 in genotype 1
naive patients are shown in FIG. 13. The model predicts that
following 10-12 weeks of dosing with the combination of TMC-435 and
PSI-7977 without ribavirin, at least 90% of HCV patients can
achieve SVR.
Example 9
Clinical Modeling for Interferon-Free DAA Combination Therapies

[0298] In addition, data from one Phase 1 and one Phase 2 study of
Danoprevir and Mercitabine were used for estimating the
pharmacokinetic and viral dynamic model parameters. Ritonavir was
co-administered with danoprevir to improve the pharmacokinetics of
danoprevir. Predictions for a 2-DAA combination with Danoprevir and
Mercitabine in genotype 1 naive patients are shown in FIG. 14. The
model predicts that following 16 weeks of dosing with the
combination of Danoprevir and Mercitabine without ribavirin, at
least 90% of HCV patients can achieve SVR.

[0299] Data from Phase 1 and Phase 2 studies of GS-9190
(tegobuvir), GS-9451 and GS-5885 were used for estimating the
pharmacokinetic and viral dynamic model parameters. Predictions for
the combination with GS-9190 (tegobuvir), GS-9451 and GS-5885 and
without ribavirin in genotype 1 naive patients are shown in FIG.
15. The model predicts that following 12 weeks of dosing with the
combination of GS-9190 (tegobuvir)+GS-9451+GS-5885+RBV and without
ribavirin, about 70% of genotype 1 naive patients can achieve SVR
and following 24 weeks of treatment >80% of genotype 1 naive
patients can achieve SVR.

[0300] Data from Phase 1 and Phase 2 studies of GS-9451 and GS-7977
(PSI-7977) were used for estimating the pharmacokinetic and viral
dynamic model parameters. Predictions for the combination with
GS-9451 and GS-7977 (PSI-7977) and without ribavirin in genotype 1
naive patients are shown in FIG. 16.
[0301] Data from Phase 1 and Phase 2 studies of GS-5885 and GS-7977
(PSI-7977) were used for estimating the pharmacokinetic and viral
dynamic model parameters. Predictions for the combination with
GS-5885 and GS-7977 (PSI-7977) and without ribavirin in genotype 1
naive patients are shown in FIG. 16.
[0302] Data from Phase 1 and Phase 2 studies of GS-9451, GS-5885
and GS-7977 (PSI-7977) were used for estimating the pharmacokinetic
and viral dynamic model parameters. Predictions for the combination
with GS-9451, GS-5885 and GS-7977 (PSI-7977) and without ribavirin
in genotype 1 naive patients are shown in FIG. 16.
[0303] The model predicts that following 12 weeks of dosing with
the combination of GS-9451 and GS-7977 (PSI-7977), or the
combination of GS-5885 and GS-7977 (PSI-7977), or the combination
of GS-9451, GS-5885 and GS-7977 (PSI-7977), and in the absence of
ribavirin, at least 90% of genotype 1 naive patients can achieve
SVR.
