Description
[0001] This application is a continuation of U.S. application Ser.
No. 11/455,200, filed 15 Jun. 2006, which is incorporated in its
entirety by reference herein.
FIELD OF THE INVENTION
[0002] The invention relates to methods and compounds for treating
chemotherapy-induced anemia. In particular, methods for treating
chemotherapy-induced anemia in subjects refractory to treatment
with recombinant human erythropoietin are encompassed herein.
BACKGROUND OF THE INVENTION
[0003] Chemotherapeutic agents are known suppressors of red cell
production by the bone marrow, and over 60% of patients treated
with chemotherapy develop anemia resulting in decreased functional
capacity and quality of life. In contrast to other common side
effects experienced by patients undergoing treatment for cancer,
chemotherapy-induced anemia (CIA) is often a "silent" side effect
with insidious symptoms. CIA can be one of the most common
underlying etiologies of the fatigue in cancer patients. Most
chemotherapeutic agents also cause stomach upset, resulting in
nausea and vomiting, which can severely reduce appetite and produce
substantial weight loss in the patient. CIA is also associated with
cognitive dysfunction, dyspnea, and depression. As a result of this
reduced quality of life, some patients choose to discontinue or
delay chemotherapeutic treatment, increasing the potential for
suboptimal outcomes. Also, CIA can adversely affect long-term
outcomes in some patients, as the anemic environment may limit the
effectiveness of some chemotherapy agents.
[0004] The incidence and severity of CIA depend on a variety of
factors, including the type, schedule, and intensity of therapy
administered, or whether the patient has received prior
myelosuppressive chemotherapy, radiation therapy, or both.
Approximately 1.3 million cancer patients undergo chemotherapy
every year in the United States, and approximately 67 percent
become anemic. Similarly, approximately 63 percent of European
chemotherapy patients develop anemia as a result of their
treatment.
[0005] Although chemotherapy-induced anemia is one of the most
common side effects of chemotherapy, it is often not recognized and
is frequently under-treated. Treatments can include red blood cell
transfusions, which may result in clinical or subclinical adverse
effects in the recipients. Several clinical trials have
demonstrated that treatment with erythropoietic agents can reduce
the need for blood transfusions and their associated complications
in patients undergoing chemotherapy. Daily subcutaneous
administration of recombinant human EPO administration at a dose of
5000 IU increases hemoglobin levels and reduces transfusion
requirements in chemotherapy-induced anemia, especially during
platinum-based chemotherapy. (Oberhoff et al. (1998) Ann Oncol
9:255-260.) However, clinical trials have suggested that a
measurable increase in thrombotic complications occurs in
chemotherapy-induced anemia patients treated with recombinant human
EPO (rhEPO). (Wun et al. (2003) Cancer 98:1514-1520.) The overall
impact on thrombosis risk has been confirmed in an independent
meta-analysis of rhEPO data. (Bohlius et al. (2005) J Natl Cancer
Inst 97(7):489-98.) Furthermore, it is estimated that 30% to 50% of
patients undergoing chemotherapy and receiving recombinant human
EPO treatment are hyporesponsive or refractory to the recombinant
EPO therapy. (J. Glaspy (2005) Expert Opin. Emerging Drugs
10:553-567.) Such patients may then have to undergo treatment with
blood transfusions, which is associated with certain risks,
including transfusion-transmitted infection, incorrect blood
transfusion, acute or delayed transfusion reaction,
post-transfusion purpura, transfusion-associated graft-verses-host
disease, etc. Thus, a need remains for effective treatments for
chemotherapy-induced anemia. In particular, there is a need for
effective treatments for chemotherapy-induced anemia in subjects
refractory to EPO therapy.
SUMMARY OF THE INVENTION
[0006] The present invention provides methods for treating or
preventing chemotherapy-induced anemia in a subject in need. In
various embodiments, the methods comprise treating or preventing
chemotherapy-induced anemia in a subject, the method comprising
administering to the subject an effective amount of an agent that
inhibits HIF hydroxylase activity.
[0007] For purposes of this invention, a subject in need is a
patient who has or who is at risk for having chemotherapy-induced
anemia. In various aspects, a subject particularly suitable for
treatment using the present methods and compounds is a subject who
is undergoing, has undergone, or will undergo chemotherapy.
[0008] It is specifically contemplated herein that the chemotherapy
comprises, in various aspects, administration of a chemotherapeutic
selected from the group consisting of: an alkylating agent; a
nitrosoureas; an antimetabolite; an anthracyclines; a topoisomerase
II inhibitor; a mitotic inhibitor; an anti-estrogen; a progestin;
an aromatase inhibitor; an anti-androgen; an LHRH agonist; a
corticosteroid hormone; a DNA alkylating agent; a taxane; a vince
alkaloid; and a microtubule poison. In certain embodiments, the
chemotherapeutic is selected from the group consisting of busulfan,
cisplatin, carboplatin, chlorambucil, cyclophosphamide, ifosfamide,
dacarbazine (DTIC), mechlorethamine (nitrogen mustard), melphalan,
temozolomide, carmustine (BCNU), lomustine (CCNU), 5-fluorouracil,
capecitabine, 6-mercaptopurine, methotrexate, gemcitabine,
cytarabine (ara-C), fludarabine, pemetrexed, daunorubicin,
doxorubicin (Adriamycin), epirubicin, idarubicin, mitoxantrone,
topotecan, irinotecan, etoposide (VP-16), teniposide, paclitaxel,
docetaxel, vinblastine, vincristine, vinorelbine, prednisone,
dexamethasone, L-asparaginase, dactinomycin, thalidomide,
tretinoin, imatinib (Gleevec), gefitinib (Iressa), erlotinib
(Tarceva), rituximab (Rituxan), bevacizumab (Avastin), tamoxifen,
fulvestrant, anastrozole, exemestane, letrozole, megestrol acetate,
bicalutamide, flutamide, leuprolide, and goserelin.
[0009] A subject suitable for treatment with the present methods
and compounds is a subject who is undergoing, has undergone, or
will undergo chemotherapy and who is refractory to or is at risk
for being refractory to recombinant human EPO therapy. Whether or
not a subject is refractory to recombinant human EPO therapy can be
determined by an assessment of the subject's response or predicted
response to treatment with recombinant human EPO. For example, in
particular embodiments, the subject is a subject refractory to
treatment with rhEPO if the subject displays an increase in
hemoglobin concentration of less than 2 g/dl, or fails to reach
levels of at least 12 g/dl, after undergoing a regimen of dosing
with recombinant human EPO. In a particular embodiment, the
response desired upon treatment with recombinant EPO can be defined
as an increase in hemoglobin of at least 2 g/dl over a twelve (12)
week dosing regimen. If a subject does not display such a response
within the required period of time, that subject is deemed
refractory to treatment with recombinant human EPO. (See, e.g.,
Ludwig et al. (1994) Blood 84:1056-1063.)
[0010] The value of the desired increase in hemoglobin, which can
be used to determine whether or not a particular subject is
refractory to recombinant human EPO treatment, may vary depending
on a number of factors, including age and gender. Thus, in various
embodiments of the present invention, a subject can be a subject
refractory to treatment with recombinant human EPO if treatment
with recombinant human EPO according to a specific dosing regimen
fails to increase the subject's hemoglobin level by at least
0.1-5.0 g/dL. In some embodiments, a subject is refractory to
treatment with recombinant human EPO if such treatment fails to
increase the subject's hemoglobin level by an amount of at least
0.2-5.0, 0.5-5.0, 1.0-5.0, 1.5-5.0, 2.0-5.0, 3.0-5.0 or 4.0-5.0
g/dL. According to further embodiments, the subject is a subject
refractory to therapy using recombinant human EPO therapy if such
therapy fails to increase the subject's hemoglobin level by an
amount of at least 0.2-2.5, 0.4-2.5, 0.6-2.5, 0.8-2.5, 1.0-2.5,
1.2-2.5, 1.4-2.5, 1.6-2.5, 1.8-2.5, or 2-2.5 g/dL, respectively.
Finally, in certain embodiments, the subject is a subject
refractory to recombinant human EPO therapy if such therapy fails
to raise the subject's hemoglobin to at least desired levels of at
least 1.0-2.0, 1.1-2.0, 1.2-2.0, 1.3-2.0, 1.4-2.0, 1.5-2.0,
1.6-2.0, 1.7-2.0, 1.8-2.0, or 1.9-2.0 g/dL, respectively.
[0011] Other parameters can be used to determine whether a
particular subject is refractory to recombinant human EPO therapy.
For example, current guidelines relating to recombinant human EPO
administration define target hemoglobin levels for an adult subject
as 12 gm/dL. Therefore, in one embodiment, a subject is a subject
refractory to recombinant human EPO therapy if treatment with
acceptable doses over a specific period of time fails to increase
hemoglobin to at least 12 gm/dL. In other embodiments, a subject is
a subject refractory to recombinant human EPO therapy if treatment
with acceptable doses over a specific period of time fails to
increase hemoglobin to at least 10 gm/dL, or at least 11
gm/dlL.
[0012] Similarly, current guidelines for recombinant human EPO
administration define a target hematocrit for an adult subject as a
hematocrit of 36%. Thus, it is contemplated that, in certain
embodiments, a subject is refractory to treatment with recombinant
human EPO if dosing with recombinant human EPO fails, over a
specified period of time, to raise the subject's hematocrit level
to at least 36%. In various embodiments, the subject is refractory
to treatment with recombinant human EPO if a recombinant human EPO
dosing regimen fails to raise the subject's hematocrit to at least
30%, at least 33%, at least 36%, at least 39%, and at least 42%,
respectively.
[0013] It is understood that, in view of the discussion, supra,
subjects suitable for treatment with the present methods and
compounds, e.g., subjects refractory to treatment with recombinant
human EPO, methods and compounds provided herein for treating such
subjects specifically encompass methods and compounds capable of
increasing the subject's hematocrit, hemoglobin, red blood cell
count, reticulocyte count, etc., to desired or recommended levels.
Failure to meet desired levels of any of these factors through
dosing with recombinant human EPO can also be used, singly or in
combination, to determine whether a subject is or may be refractory
to treatment with recombinant human EPO. For example, in one
aspect, a subject is a refractory subject suitable for treatment
using the present methods if, after two weeks of therapy, the
subject has a serum EPO level of or less than 100 mU/mL, and has
demonstrated an increase in hemoglobin of less than 0.5 g/dL. In
another aspect, the subject is a subject refractory to recombinant
human EPO therapy if, after two weeks of recombinant EPO therapy,
the subject displays a serum ferritin level of greater than or
equal to 400 ng/ml.
[0014] The invention provides in one embodiment a method for
reducing weight loss in a subject who is undergoing, has undergone,
or is expected to undergo chemotherapy, the method comprising
administering to the subject an effective amount of an agent that
inhibits HIF hydroxylase activity.
[0015] In various embodiments, an agent for use in the present
methods is a 2-oxoglutarate mimetic. In certain embodiments, the
agent used in the present methods is a compound selected from the
group consisting of the compounds of Formula I, Formula II, Formula
III, and Formula IV. Formula I includes, but is not limited to,
compounds of Formulae Ia, Ib, Ic, Id, and Ie; compounds of Formula
Ie include, but are not limited to, compounds of Formulae Ie(i),
Ie(ii), Ie(iii), and Ie(iv). Formula II includes but is not limited
to, the compounds of Formula IIIa.
[0016] In particular embodiments, an agent of the present invention
is selected from the group consisting of a pyridine-2-carboxamide,
a quinoline-2-carboxamide, an isoquinoline-3-carboxamide, a
cinnoline-3-carboxamide, a beta-carboline-3-carboxamide, and a
4-oxo-[1,10]-phenanthroline.
[0017] In particular embodiments, an agent for use in the present
methods is selected from the group consisting of: Compound A [(1
Chloro-4-hydroxy-isoquinoline-3-carbonyl)-amino]-acetic acid];

Invention
[0032] The present invention relates to the discovery that
administration of an agent that inhibits HIF hydroxylase activity
is therapeutically effective in treating chemotherapy-induced
anemia in subjects who have or who are at risk for having
chemotherapy-induced anemia, wherein such subjects are refractory
to or are at risk for being refractory to treatment with
recombinant human EPO.
[0033] Therefore, the present invention provides methods for
treating or preventing chemotherapy-induced anemia in a subject in
need. In various embodiments, the methods comprise treating or
preventing chemotherapy-induced anemia in a subject, the method
comprising administering to the patient an effective amount of an
agent that inhibits HIF hydroxylase activity.
[0034] For purposes of this invention, a subject in need is a
patient who has or who is at risk for having chemotherapy-induced
anemia. In various aspects, a subject particularly suitable for
treatment using the present methods and compounds is a subject who
is undergoing, has undergone, or will undergo chemotherapy.
[0035] In the context of cancer, chemotherapy refers to the use of
various cytotoxic agents to treat cancer. It is specifically
contemplated that the present methods and compounds are used to
treat chemotherapy-induced anemia, e.g., anemia that develops in
associated with a chemotherapy regimen, in a subject who is
undergoing treatment with any chemotherapeutic agent, or subjects
who have undergone or who are expected to undergo such
treatment.
[0036] Therefore, in one embodiment, the present invention provides
a method for treating or preventing anemia of cancer in a subject
having or at risk for having such a disease, wherein the subject is
refractory to or is at risk for being refractory to recombinant
human EPO therapy, and further wherein the subject is undergoing
treatment with one or more chemotherapeutics. The treatment with
the one or more chemotherapeutics may involve administration of the
chemotherapeutic agents that is simultaneous, separate, or
sequential to administration of the agent that inhibits HIF
hydroxylase activity.
[0037] Suitable chemotherapeutics will be well known to the skilled
person in the art. Non-limiting examples of such chemotherapeutic
agents include, for example, the chemotherapeutics may be selected
from the group consisting of alkylating agents; nitrosoureas;
antimetabolites; anthracyclines and related drugs; topoisomerase II
inhibitors; mitotic inhibitors and corticosteroid hormones. Known
alkylating agents include busulfan, cisplatin, carboplatin,
chlorambucil, cyclophosphamide, ifosfamide, dacarbazine (DTIC),
mechlorethamine (nitrogen mustard), melphalan and temozolomide.
Known nitrosoureas include carmustine (BCNU) and lomustine (CCNU).
Known antimetabolites include 5-fluorouracil, capecitabine,
6-mercaptopurine, methotrexate, gemcitabine, cytarabine (ara-C),
fludarabine and pemetrexed. Known anthracyclines and related drugs
include daunorubicin, doxorubicin (Adriamycin), epirubicin,
idarubicin and mitoxantrone. Known topoisomerase II inhibitors
include topotecan, irinotecan, etoposide (VP-16) and teniposide.
Known mitotic inhibitors include taxanes (paclitaxel, docetaxel)
and the vinca alkaloids (vinblastine, vincristine and vinorelbine).
Known corticosteroid hormones include prednisone and
dexamethasone.
[0038] The chemotherapeutics may also be selected from other known
chemotherapeutics, e.g. L-asparaginase, dactinomycin, thalidomide,
tretinoin, imatinib (Gleevec), gefitinib (Iressa), erlotinib
(Tarceva), rituximab (Rituxan), bevacizumab (Avastin),
anti-estrogens (tamoxifen, fulvestrant), aromatase inhibitors
(anastrozole, exemestane, letrozole), progestins (megestrol
acetate), anti-androgens (bicalutamide, flutamide) and LHRH
agonists (leuprolide, goserelin).
[0039] It is particularly contemplated that the chemotherapeutic
agent can be, for example, a microtubule poison, a DNA alkylating
agent, etc. Suitable microtubule poisons include, but are not
limited to, paclitaxel. Suitable DNA alkylating agents include,
e.g., carboplatin, etc.
[0040] A subject suitable for treatment with the present methods
and compounds is a subject who is refractory to or is at risk for
being refractory to recombinant human EPO therapy. Whether or not a
subject is refractory to recombinant human EPO therapy can be
determined by an assessment of the subject's response or predicted
response to treatment with recombinant human EPO. For example, in
one particular embodiment, the response desired upon treatment with
recombinant human EPO can be defined as an increase in hemoglobin
of at least 2 g/dl over a twelve (12) week dosing regimen. If a
subject does not display such a response within the required period
of time, that subject is deemed refractory to treatment with
recombinant human EPO. (See, e.g., Ludwig et al. (1994) Blood
84:1056-1063.)
[0041] The value of the desired increase in hemoglobin, used to
determine whether or not a particular subject is refractory to EPO
treatment, may vary depending on a number of factors, including age
and gender. Various factors, including hemoglobin or Hb
concentration, serum EPO levels, and hematocrit, can be used singly
or in combination to assess whether a particular subject is
refractory to or at risk for being refractory to recombinant human
EPO therapy.
[0042] Thus, in various embodiments of the present invention, a
subject can be a subject refractory to treatment with recombinant
human EPO if treatment with recombinant human EPO according to a
specific dosing regimen fails to increase the subject's hemoglobin
level by at least 0.1-5.0 g/dL. In some embodiments, a subject is
refractory to treatment with recombinant human EPO if such
treatment fails to increase the subject's hemoglobin level by an
amount of at least 0.2-5.0, 0.5-5.0, 1.0-5.0, 1.5-5.0, 2.0-5.0,
3.0-5.0 or 4.0-5.0 g/dL. According to further embodiments, the
subject is a subject refractory to therapy using recombinant human
EPO therapy if such therapy fails to increase the subject's
hemoglobin level by an amount of at least 0.2-2.5, 0.4-2.5,
0.6-2.5, 0.8-2.5, 1.0-2.5, 1.2-2.5, 1.4-2.5, 1.6-2.5, 1.8-2.5, or
2-2.5 g/dL, respectively. Finally, in certain embodiments, the
subject is a subject refractory to recombinant human EPO therapy if
such therapy fails to raise the subject's hemoglobin to at least
desired levels of at least 1.0-2.0, 1.1-2.0, 1.2-2.0, 1.3-2.0,
1.4-2.0, 1.5-2.0, 1.6-2.0, 1.7-2.0, 1.8-2.0, or 1.9-2.0 g/dL,
respectively.
[0043] Other parameters can be used to determine whether a
particular subject is refractory to recombinant human EPO therapy.
For example, current guidelines relating to recombinant human EPO
administration define target hemoglobin levels for an adult subject
as 12 gm/dL. Therefore, in one embodiment, a subject is a subject
refractory to recombinant human EPO therapy if treatment with
acceptable doses over specific period of time fail to increase
hemoglobin to at least 12 gm/dL. In other embodiments, a subject is
a subject refractory to recombinant human EPO therapy if treatment
with acceptable doses over specific period of time fail to increase
hemoglobin to at least 10 gm/dL, or at least 11 gm/dL.
[0044] Similarly, current guidelines for recombinant human EPO
administration define a target hematocrit level for an adult
subject as a hematocrit of 36%. Thus, it is contemplated that, in
certain embodiments, a subject is refractory to treatment with
recombinant human EPO if dosing with recombinant human EPO fails,
over a specified period of time, to raise the subject's hematocrit
level to at least 36%. In various embodiments, the subject is
refractory to treatment with recombinant human EPO if a recombinant
human EPO dosing regimen fails to raise the subject's hematocrit to
at least 30%, at least 33%, at least 36%, at least 39%, and at
least 42%, respectively.
[0045] It is noted that various factors, including hemoglobin or Hb
concentration, hematocrit, reticolycte or RBC count, serum ferritin
levels, and serum EPO levels can be measured by any of the methods
available in the art and can be used singly or in combination to
determine whether a particular subject is refractory, or may be
refractory, to treatment with recombinant EPO. For example, in one
embodiment, it is contemplated that serum EPO levels and Hb
concentration are used in combination to identify subjects suitable
for treatment with the present methods and compounds. In a specific
embodiment, the subject is a refractory subject suitable for
treatment using the present methods if, after two weeks of therapy,
the subject has a serum EPO level of or less than 100 mU/mL, and
has demonstrated an increase in hemoglobin of less than 0.5 g/dL.
In another aspect, the subject is a subject refractory to
recombinant human EPO therapy if, after two weeks of recombinant
human EPO therapy, a high serum ferritin level, for example, a
serum ferritin level of greater than or equal to 400 ng/ml.
[0046] In particular, it is demonstrated herein that HIF
hydroxylase inhibitors effectively treated chemotherapy-induced
anemia in animal models of chemotherapy-induced anemia. (See, e.g.,
Examples 1, 2, and 3.)
[0047] The present invention demonstrates that methods and
compounds of the invention are effective in treating or preventing
the development of chemotherapy-induced anemia. Additionally, the
present invention demonstrates that methods and compounds of the
invention are useful for limiting weight loss associated with
chemotherapy.
Methods
[0048] Various methods are provided herein. In one aspect, the
methods comprise administering to a subject an agent that inhibits
HIF hydroxylase activity. HIF hydroxylase activity can include,
e.g., the activity of any enzyme selected from the group consisting
of HIF prolyl hydroxylase, HIF asparaginyl hydroxylase, and HIF
lysyl hydroxylase. In preferred embodiments, the enzyme is a HIF
prolyl hydroxylase enzyme, e.g., EGLN-1, EGLN-2, EGLN-3, etc. (See,
e.g., Taylor (2001) Gene 275:125-132; Epstein et al. (2001) Cell
107:43-54; and Bruick and McKnight (2001) Science
294:1337-1340.)
[0049] A HIF hydroxylase is any enzyme capable of hydroxylating a
residue in the HIF protein. HIF hydroxylases include HIF prolyl
hydroxylases. In certain embodiments, the residue hydroxylated by
HIF prolyl hydroxylase includes the proline found within the motif
LXXLAP, e.g., as occurs in the human HIF-1.alpha. native sequence
at L.sub.397TLLAP and L.sub.559EMLAP. HIF prolyl hydroxylase
includes members of the Egl-Nine (EGLN) gene family described by
Taylor (2001, Gene 275:125-132), and characterized by Aravind and
Koonin (2001, Genome Biol 2:RESEARCH0007), Epstein et al. (2001,
Cell 107:43-54), and Bruick and McKnight (2001, Science
294:1337-1340). Examples of HIF prolyl hydroxylase enzymes include
human SM-20 (EGLN1) (GenBank Accession No. AAG33965; Dupuy et al.
(2000) Genomics 69:348-54), EGLN2 isoform 1 (GenBank Accession No.
CAC42510; Taylor, supra), EGLN2 isoform 2 (GenBank Accession No.
NP.sub.--060025), and EGLN3 (GenBank Accession No. CAC42511;
Taylor, supra); mouse EGLN1 (GenBank Accession No. CAC42515), EGLN2
(GenBank Accession No. CAC42511), and EGLN3 (SM-20) (GenBank
Accession No. CAC42517); and rat SM-20 (GenBank Accession No.
AAA19321). Additionally, HIF prolyl hydroxylase may include
Caenorhabditis elegans EGL-9 (GenBank Accession No. AAD56365) and
Drosophila melanogaster CG1114 gene product (GenBank Accession No.
AAF52050). HIF prolyl hydroxylase also includes any fragment of the
foregoing full-length proteins that retain at least one structural
or functional characteristic.
[0050] An agent that inhibits HIF hydroxylase activity is any agent
that reduces or otherwise modulates the activity of a HIF
hydroxylase enzyme. In particular embodiments of the present
invention, the agent that inhibits HIF hydroxylase activity is a
structural mimetics of 2-oxoglutarate. Such compounds may inhibit
the target 2-oxoglutarate dioxygenase enzyme family member
competitively with respect to 2-oxoglutarate. (Majamaa et al.
(1984) Eur J Biochem 138:239-245; and Majamaa et al. (1985) Biochem
J 229:127-133.) Hydroxylase inhibitors specifically contemplated
for use in the present methods are described, e.g., in Majamaa et
al., supra; Kivirikko and Myllyharju (1998) Matrix Biol 16:357-368;

International Publication No. WO 04/108121. These compounds
include, but are not limited to, compounds of Formula IIIa. Further
exemplary compounds are according to Formula IV, as described
below.
[0053] In certain embodiments, a compound of the invention is a
compound that inhibits HIF hydroxylase activity. In various
embodiments, the activity is due to a HIF prolyl hydroxylase, such
as, for example, EGLN1, EGLN2, or EGLN3, etc. In other embodiments,
the activity is due to a HIF asparaginyl hydroxylase, such as, for
example, including, but not limited to, FIH. A preferred compound
of the invention is a compound that inhibits HIF prolyl hydroxylase
activity. The inhibition can be direct or indirect, can be
competitive or non-competitive, etc.
[0054] In one aspect, a compound of the invention is any compound
that inhibits or otherwise modulates the activity of a
2-oxoglutarate dioxygenase enzyme. 2-oxoglutarate dioxygenase
enzymes include, but are not limited to, hydroxylase enzymes.
Hydroxylase enzymes hydroxylate target substrate residues and
include, for example, prolyl, lysyl, asparaginyl (asparagyl,
aspartyl)hydroxylases, etc. Hydroxylases are sometimes described by
target substrate, e.g., HIF hydroxylases, procollagen hydroxylases,
etc., and/or by targeted residues within the substrate, e.g.,
prolyl hydroxylases, lysyl hydroxylases, etc., or by both, e.g.,
HIF prolyl hydroxylases, procollagen prolyl hydroxylases, etc.
Representative 2-oxoglutarate dioxygenase enzymes include, but are
not limited to, HIF hydroxylases, including HIF prolyl
hydroxylases, e.g., EGLN1, EGLN2, and EGLN3, HIF asparaginyl
hydroxylases, e.g., factor inhibiting HIF (FIH), etc.; procollagen
hydroxylases, e.g., procollagen lysyl hydroxylases, procollagen
prolyl hydroxylases, e.g., procollagen prolyl 3-hydroxylase,
procollagen prolyl 4-hydroxylase .alpha.(I) and .alpha.(II), etc.;
thymine 7-hydroxylase; aspartyl (asparaginyl) .beta.-hydroxylase;
.epsilon.-N-trimethyllysine hydroxylase; .gamma.-butyrobetaine
hydroxylase, etc. Although enzymatic activity can include any
activity associated with any 2-oxoglutarate dioxygenase, the
hydroxylation of amino acid residues within a substrate is
specifically contemplated. Although hydroxylation of proline and/or
asparagine residues within a substrate is specifically included,
hydroxylation of other amino acids is also contemplated.
[0055] In one aspect, a compound of the invention that shows
inhibitory activity toward one or more 2-oxoglutarate dioxygenase
enzyme may also show inhibitory activity toward one or more
additional 2-oxoglutarate dioxygenase enzymes, e.g., a compound
that inhibits the activity of a HIF hydroxylase may additionally
inhibit the activity of a collagen prolyl hydroxylase, a compound
that inhibits the activity of a HIF prolyl hydroxylase may
additionally inhibit the activity of a HIF asparaginyl hydroxylase,
etc.
[0056] In some aspects, compounds of the present invention include,
for example, structural mimetics of 2-oxoglutarate. Such compounds
may inhibit the target 2-oxoglutarate dioxygenase enzyme family
member competitively with respect to 2-oxoglutarate and
noncompetitively with respect to iron. (Majamaa et al. (1984) Eur J
Biochem 138:239-245; and Majamaa et al. Biochem J 229:127-133.)
[0057] In certain embodiments, a compound of the present invention
is a compound of Formula I. In particular embodiments, the
2-oxoglutarate mimetic is a pyridine-2-carboxamide including, but
not limited to, compounds of Formula I. In particular embodiments,
the 2-oxoglutarate mimetic is a quinoline-2-carboxamide including,
but not limited to, compounds of Formula Ia. In other embodiments,
the 2-oxoglutarate mimetic is an isoquinoline-3-carboxamide
including, but not limited to, compounds of Formula Ib. In
additional embodiments, the 2-oxoglutarate mimetic is a
cinnoline-3-carboxamide including, but not limited to, compounds of
Formula Ic, or is a beta-carboline-3-carboxamide including, but not
limited to, compounds of Formula Id.

[0288] The term "amino acid" refers to any of the naturally
occurring amino acids, as well as synthetic analogs (e.g.,
D-stereoisomers of the naturally occurring amino acids, such as
D-threonine) and derivatives thereof. .alpha.-Amino acids comprise
a carbon atom to which is bonded an amino group, a carboxyl group,
a hydrogen atom, and a distinctive group referred to as a "side
chain". The side chains of naturally occurring amino acids are well
known in the art and include, for example, hydrogen (e.g., as in
glycine), alkyl (e.g., as in alanine, valine, leucine, isoleucine,
proline), substituted alkyl (e.g., as in threonine, serine,
methionine, cysteine, aspartic acid, asparagine, glutamic acid,
glutamine, arginine, and lysine), arylalkyl (e.g., as in
phenylalanine and tryptophan), substituted arylalkyl (e.g., as in
tyrosine), and heteroarylalkyl (e.g., as in histidine). Unnatural
amino acids are also known in the art, as set forth in, for
example, Williams (ed.), Synthesis of Optically Active
.alpha.-Amino Acids, Pergamon Press (1989); Evans et al., J. Amer.
Chem. Soc., 112:4011-4030 (1990); Pu et al., J. Amer. Chem. Soc.,
56:1280-1283 (1991); Williams et al., J. Amer. Chem. Soc.,
113:9276-9286 (1991); and all references cited therein. The present
invention includes the side chains of unnatural amino acids as
well.
[0289] "Pharmaceutically acceptable salt" refers to
pharmaceutically acceptable salts of a compound, which salts are
derived from a variety of organic and inorganic counter ions well
known in the art and include, by way of example only, sodium,
potassium, calcium, magnesium, ammonium, tetraalkylammonium, and
the like; and when the molecule contains a basic functionality,
salts of organic or inorganic acids, such as hydrochloride,
hydrobromide, tartrate, mesylate, acetate, maleate, oxalate and the
like.
[0290] The term "prodrug" refers to compounds of this invention
which have been modified to include a physiologically and
biocompatible removable group which group is removed in vivo to
provide for the active drug, a pharmaceutically acceptable salt
thereof or a biologically active metabolite thereof. Suitable
removable groups are well known in the art and particularly
preferred removable groups include esters of the carboxylic acid
moiety on the glycine substituent. Preferably such esters include
those derived from alkyl alcohols, substituted alkyl alcohols,
hydroxy substituted aryls and heteroaryls and the like. Another
preferred removable group are the amides formed from the carboxylic
acid moiety on the glycine substituent. Suitable amides are derived
from amines of the formula HNR.sup.20R.sup.21 where R.sup.20 and
R.sup.21 are independently hydrogen, alkyl, substituted alkyl,
aryl, substituted aryl, and the like.
[0291] It is understood that in all substituted groups defined
above, polymers arrived at by defining substituents with further
substituents to themselves (e.g., substituted aryl having a
substituted aryl group as a substituent which is itself substituted
with a substituted aryl group, etc.) are not intended for inclusion
herein. In such cases, the maximum number of such substituents is
three. That is to say that each of the above definitions is
constrained by a limitation that, for example, substituted aryl
groups are limited to -substituted aryl-(substituted
aryl)-substituted aryl.
[0292] Similarly, it is understood that the above definitions are
not intended to include impermissible substitution patterns (e.g.,
methyl substituted with 5 fluoro groups or a hydroxyl group alpha
to ethenylic or acetylenic unsaturation). Such impermissible
substitution patterns are well known to the skilled artisan.
Methods for Identifying Compounds
[0293] Methods for identifying compounds of the invention are also
provided. Assays for hydroxylase activity are standard in the art.
Such assays can directly or indirectly measure hydroxylase
activity. For example, an assay can measure hydroxylated residues,
e.g., proline, asparagine, etc., present in the enzyme substrate,
e.g., a target protein, a synthetic peptide mimetic, or a fragment
thereof. (See, e.g., Palmerini et al. (1985) J Chromatogr
339:285-292.) A reduction in hydroxylated residue, e.g., proline or
asparagine, in the presence of a compound is indicative of a
compound that inhibits hydroxylase activity. Alternatively, assays
can measure other products of the hydroxylation reaction, e.g.,
formation of succinate from 2-oxoglutarate. (See, e.g., Cunliffe et
al. (1986) Biochem J 240:617-619.) Kaule and Gunzler (1990; Anal
Biochem 184:291-297) describe an exemplary procedure that measures
production of succinate from 2-oxoglutarate.
[0294] Procedures such as those described above can be used to
identify compounds that modulate HIF hydroxylase activity. Target
protein may include HIF.alpha. or a fragment thereof, e.g.,
HIF(556-575). Enzyme may include, e.g., HIF prolyl hydroxylase
(see, e.g., GenBank Accession No. AAG33965, etc.) or HIF
asparaginyl hydroxylase (see, e.g., GenBank Accession No. AAL27308,
etc.), obtained from any source. Enzyme may also be present in a
crude cell lysate or in a partially purified form. For example,
procedures that measure HIF hydroxylase activity are described in
Ivan et al. (2001, Science 292:464-468; and 2002, Proc Natl Acad
Sci USA 99:13459-13464) and Hirsila et al. (2003, J Biol Chem
278:30772-30780); additional methods are described in International
Publication No. WO 03/049686. Measuring and comparing enzyme
activity in the absence and presence of the compound will identify
compounds that inhibit hydroxylation of HIF.alpha..
[0295] For clarity, an agent for use in the present methods is any
compound that stabilizes HIF.alpha.. Methods for determining
whether or not a particular agent stabilizes HIF.alpha. are
available in the art and are described, supra.
Modes of Administration
[0296] The compositions of the present invention can be delivered
directly or in pharmaceutical compositions containing excipients,
as is well known in the art. The present methods of treatment
involve administration of an effective amount of a compound of the
present invention to a subject having or at risk for having
chemotherapy-induced anemia.
[0297] An effective amount, e.g., dose, of compound or drug can
readily be determined by routine experimentation, as can an
effective and convenient route of administration and an appropriate
formulation. Various formulations and drug delivery systems are
available in the art. (See, e.g., Gennaro, ed. (2000) Remington's
Pharmaceutical Sciences, supra; and Hardman, Limbird, and Gilman,
eds. (2001) The Pharmacological Basis of Therapeutics, supra.)
[0298] Suitable routes of administration may, for example, include
oral, rectal, topical, nasal, pulmonary, ocular, intestinal, and
parenteral administration. Primary routes for parenteral
administration include intravenous, intramuscular, and subcutaneous
administration. Secondary routes of administration include
intraperitoneal, intra-arterial, intra-articular, intracardiac,
intracisternal, intradermal, intralesional, intraocular,
intrapleural, intrathecal, intrauterine, and intraventricular
administration. The indication to be treated, along with the
physical, chemical, and biological properties of the drug, dictate
the type of formulation and the route of administration to be used,
as well as whether local or systemic delivery would be
preferred.
[0299] In preferred embodiments, the compounds of the present
invention are administered orally. For example, in certain
embodiments, the invention provides for oral administration of a
compound selected from the group consisting of: Compound A [(1
Chloro-4-hydroxy-isoquinoline-3-carbonyl)-amino]-acetic acid];
Compound B
[((S)-2-[(4-Hydroxy-7-phenoxy-6,7-dihydro-isoquinoline-3-carbonyl)-amino]-

[0300] Pharmaceutical dosage forms of a compound of the invention
may be provided in an instant release, controlled release,
sustained release, or target drug-delivery system. Commonly used
dosage forms include, for example, solutions and suspensions,
(micro-) emulsions, ointments, gels and patches, liposomes,
tablets, dragees, soft or hard shell capsules, suppositories,
ovules, implants, amorphous or crystalline powders, aerosols, and
lyophilized formulations. Depending on route of administration
used, special devices may be required for application or
administration of the drug, such as, for example, syringes and
needles, inhalers, pumps, injection pens, applicators, or special
flasks. Pharmaceutical dosage forms are often composed of the drug,
an excipient(s), and a container/closure system. One or multiple
excipients, also referred to as inactive ingredients, can be added
to a compound of the invention to improve or facilitate
manufacturing, stability, administration, and safety of the drug,
and can provide a means to achieve a desired drug release profile.
Therefore, the type of excipient(s) to be added to the drug can
depend on various factors, such as, for example, the physical and
chemical properties of the drug, the route of administration, and
the manufacturing procedure. Pharmaceutically acceptable excipients
are available in the art, and include those listed in various
pharmacopoeias. (See, e.g., USP, JP, EP, and BP, FDA web page
(www.fda.gov), Inactive Ingredient Guide 1996, and Handbook of
Pharmaceutical Additives, ed. Ash; Synapse Information Resources,
Inc. 2002.)
[0301] Pharmaceutical dosage forms of a compound of the present
invention may be manufactured by any of the methods well-known in
the art, such as, for example, by conventional mixing, sieving,
dissolving, melting, granulating, dragee-making, tabletting,
suspending, extruding, spray-drying, levigating, emulsifying,
(nano/micro-) encapsulating, entrapping, or lyophilization
processes. As noted above, the compositions of the present
invention can include one or more physiologically acceptable
inactive ingredients that facilitate processing of active molecules
into preparations for pharmaceutical use.
[0302] Proper formulation is dependent upon the desired route of
administration. For intravenous injection, for example, the
composition may be formulated in aqueous solution, if necessary
using physiologically compatible buffers, including, for example,
phosphate, histidine, or citrate for adjustment of the formulation
pH, and a tonicity agent, such as, for example, sodium chloride or
dextrose. For transmucosal or nasal administration, semisolid,
liquid formulations, or patches may be preferred, possibly
containing penetration enhancers. Such penetrants are generally
known in the art. For oral administration, the compounds can be
formulated in liquid or solid dosage forms and as instant or
controlled/sustained release formulations. Suitable dosage forms
for oral ingestion by a subject include tablets, pills, dragees,
hard and soft shell capsules, liquids, gels, syrups, slurries,
suspensions, and emulsions. The compounds may also be formulated in
rectal compositions, such as suppositories or retention enemas,
e.g., containing conventional suppository bases such as cocoa
butter or other glycerides.
[0303] Solid oral dosage forms can be obtained using excipients,
which may include, fillers, disintegrants, binders (dry and wet),
dissolution retardants, lubricants, glidants, antiadherants,
cationic exchange resins, wetting agents, antioxidants,
preservatives, coloring, and flavoring agents. These excipients can
be of synthetic or natural source. Examples of such excipients
include cellulose derivatives, citric acid, dicalcium phosphate,
gelatine, magnesium carbonate, magnesium/sodium lauryl sulfate,
mannitol, polyethylene glycol, polyvinyl pyrrolidone, silicates,
silicium dioxide, sodium benzoate, sorbitol, starches, stearic acid
or a salt thereof, sugars (i.e. dextrose, sucrose, lactose, etc.),
talc, tragacanth mucilage, vegetable oils (hydrogenated), and
waxes. Ethanol and water may serve as granulation aides. In certain
instances, coating of tablets with, for example, a taste-masking
film, a stomach acid resistant film, or a release-retarding film is
desirable. Natural and synthetic polymers, in combination with
colorants, sugars, and organic solvents or water, are often used to
coat tablets, resulting in dragees. When a capsule is preferred
over a tablet, the drug powder, suspension, or solution thereof can
be delivered in a compatible hard or soft shell capsule.
[0304] In one embodiment, the compounds of the present invention
can be administered topically, such as through a skin patch, a
semi-solid or a liquid formulation, for example a gel, a
(micro)-emulsion, an ointment, a solution, a
(nano/micro)-suspension, or a foam. The penetration of the drug
into the skin and underlying tissues can be regulated, for example,
using penetration enhancers; the appropriate choice and combination
of lipophilic, hydrophilic, and amphiphilic excipients, including
water, organic solvents, waxes, oils, synthetic and natural
polymers, surfactants, emulsifiers; by pH adjustment; and use of
complexing agents. Other techniques, such as iontophoresis, may be
used to regulate skin penetration of a compound of the invention.
Transdermal or topical administration would be preferred, for
example, in situations in which local delivery with minimal
systemic exposure is desired.
[0305] For administration by inhalation, or administration to the
nose, the compounds for use according to the present invention are
conveniently delivered in the form of a solution, suspension,
emulsion, or semisolid aerosol from pressurized packs, or a
nebuliser, usually with the use of a propellant, e.g., halogenated
carbons derived from methan and ethan, carbon dioxide, or any other
suitable gas. For topical aerosols, hydrocarbons like butane,
isobutene, and pentane are useful. In the case of a pressurized
aerosol, the appropriate dosage unit may be determined by providing
a valve to deliver a metered amount. Capsules and cartridges of,
for example, gelatin, for use in an inhaler or insufflator, may be
formulated. These typically contain a powder mix of the compound
and a suitable powder base such as lactose or starch.
[0306] Compositions formulated for parenteral administration by
injection are usually sterile and, can be presented in unit dosage
forms, e.g., in ampoules, syringes, injection pens, or in
multi-dose containers, the latter usually containing a
preservative. The compositions may take such forms as suspensions,
solutions, or emulsions in oily or aqueous vehicles, and may
contain formulatory agents, such as buffers, tonicity agents,
viscosity enhancing agents, surfactants, suspending and dispersing
agents, antioxidants, biocompatible polymers, chelating agents, and
preservatives. Depending on the injection site, the vehicle may
contain water, a synthetic or vegetable oil, and/or organic
co-solvents. In certain instances, such as with a lyophilized
product or a concentrate, the parenteral formulation would be
reconstituted or diluted prior to administration. Depot
formulations, providing controlled or sustained release of a
compound of the invention, may include injectable suspensions of
nano/micro particles or nano/micro or non-micronized crystals.
Polymers such as poly(lactic acid), poly(glycolic acid), or
copolymers thereof, can serve as controlled/sustained release
matrices, in addition to others well known in the art. Other depot
delivery systems may be presented in form of implants and pumps
requiring incision.
[0307] Suitable carriers for intravenous injection for the
molecules of the invention are well-known in the art and include
water-based solutions containing a base, such as, for example,
sodium hydroxide, to form an ionized compound, sucrose or sodium
chloride as a tonicity agent, for example, the buffer contains
phosphate or histidine. Co-solvents, such as, for example,
polyethylene glycols, may be added. These water-based systems are
effective at dissolving compounds of the invention and produce low
toxicity upon systemic administration. The proportions of the
components of a solution system may be varied considerably, without
destroying solubility and toxicity characteristics. Furthermore,
the identity of the components may be varied. For example,
low-toxicity surfactants, such as polysorbates or poloxamers, may
be used, as can polyethylene glycol or other co-solvents,
biocompatible polymers such as polyvinyl pyrrolidone may be added,
and other sugars and polyols may substitute for dextrose.
[0308] For composition useful for the present methods of treatment,
a therapeutically effective dose can be estimated initially using a
variety of techniques well-known in the art. Initial doses used in
animal studies may be based on effective concentrations established
in cell culture assays. Dosage ranges appropriate for human
subjects can be determined, for example, using data obtained from
animal studies and cell culture assays.
[0309] A therapeutically effective dose or amount of a compound,
agent, or drug of the present invention refers to an amount or dose
of the compound, agent, or drug that results in amelioration of
symptoms or a prolongation of survival in a subject. Toxicity and
therapeutic efficacy of such molecules can be determined by
standard pharmaceutical procedures in cell cultures or experimental
animals, e.g., by determining the LD50 (the dose lethal to 50% of
the population) and the ED50 (the dose therapeutically effective in
50% of the population). The dose ratio of toxic to therapeutic
effects is the therapeutic index, which can be expressed as the
ratio LD50/ED50. Agents that exhibit high therapeutic indices are
preferred.
[0310] The effective amount or therapeutically effective amount is
the amount of the compound or pharmaceutical composition that will
elicit the biological or medical response of a tissue, system,
animal, or human that is being sought by the researcher,
veterinarian, medical doctor, or other clinician, e.g., an increase
in hemoglobin levels, an increase in hematocrit, amelioration of
the symptoms of chemotherapy-induced anemia, etc.
[0311] Dosages preferably fall within a range of circulating
concentrations that includes the ED50 with little or no toxicity.
Dosages may vary within this range depending upon the dosage form
employed and/or the route of administration utilized. The exact
formulation, route of administration, dosage, and dosage interval
should be chosen according to methods known in the art, in view of
the specifics of a subject's condition.
[0312] Dosage amount and interval may be adjusted individually to
provide plasma levels of the active moiety that are sufficient to
achieve the desired effects, i.e., minimal effective concentration
(MEC). The MEC will vary for each compound but can be estimated
from, for example, in vitro data and animal experiments. Dosages
necessary to achieve the MEC will depend on individual
characteristics and route of administration. In cases of local
administration or selective uptake, the effective local
concentration of the drug may not be related to plasma
concentration.

Example 1
Compounds and Methods of the Invention are Effective at Treating
Chemotherapy-Induced Anemia
[0320] The following study was performed to examine the effect of
compounds and methods of the present invention on treatment of
chemotherapy-induced anemia. Fifteen Sprague Dawley male rats
(280-300 g) were obtained from Charles River Laboratories. On day
0, rats were treated by intraperitoneal (i.p.) injection with a
single dose of saline (control; n=3) at 8 ml/kg, or Cisplatin (CP;
Bedford Laboratories, Bedford Ohio) at either 7 mg/kg (7 ml/kg;
n=6) or 10 mg/kg (10 ml/kg; n=6). Blood samples (0.2 ml) were
collected on days 5, 9, and 16 as follows. Animals were
anesthetized with isoflurane and 0.2 ml of blood was collected from
the tail vein into a MICROTAINER EDTA-2K tube (Becton-Dickinson).
Blood samples were processed for hematocrit as described above to
determine the degree of anemia produced in each animal.
[0321] Beginning on day 19 of the study, one half of each
cisplatin-treated group (n=3.times.2) and all of the control group
were treated by oral gavage once per day for 5 consecutive days
with a 2 ml/kg volume of 0.5% CMC (Sigma-Aldrich). The other half
of each cisplatin-treated group (n=3.times.2) was treated by oral
gavage once per day for five consecutive days with a 2 ml/kg volume
of 2.5% of a representative compound of the present invention,
Compound A (25 mg/ml in 0.5% CMC). Blood samples (0.5 ml) were
collected as described above immediately prior to treatment and 4
days after treatment initiation. Blood samples were analyzed for
CBC and reticulocyte counts as described above. On day 9 after
initiation of oral treatment, a blood sample (0.1 ml) was collected
and processed for hematocrit as described above.
[0322] As shown in FIG. 1A, administration of either 7 mg/kg
cisplatin or 10 mg/kg cisplatin reduced hematocrit by 14% and 22%,
respectively, compared to that in non-treated control animals.
Administration of Compound A, however, increased hematocrit in the
Cisplatin-treated animals 4 days after initiating treatment with
Compound A. Hematocrit levels were significantly higher than
non-treated counterparts by day 9 post-treatment. Specifically,
hematocrit levels in animals initially exposed to 7 mg/kg cisplatin
and subsequently treated with Compound A were at or above
hematocrit levels in non-treated control (i.e., no chemotherapeutic
agent administration) by day 9.
[0323] As shown in FIG. 1B, administration of Compound A to animals
treated with the chemotherapy agent Cisplatin increased the percent
circulating reticulocytes compared to cisplatin-treated animals
without treatment with Compound A.
[0324] These results showed that methods and compounds of the
present invention increased hematocrit and reticulocyte counts in
an animal model of chemotherapy-induced anemia. Therefore, the
present compounds and methods are effective at treating
chemotherapy-induced anemia.
Example 2
Compounds and Methods of the Invention are Effective at Treating
Chemotherapy-Induced Anemia
[0325] To examine the effect of methods and compounds of the
present invention on treatment of chemotherapy-induced anemia, the
following study was performed. The human H-460 lung cancer cell
line used was obtained from the National Cancer Institute. (Brower
et al., (1986) Cancer Res 46:798-806.) Animals were maintained in a
HEPA-filtered environment during the experimental period. Cages,
food, and bedding were autoclaved. Animal diets were obtained from
Harlan Teklad (Madison, Wis.). Hydrochloric acid, 0.15% (v/v), was
added to the drinking water.
[0326] Compounds of the invention were pre-formulated in an aqueous
vehicle consisting of 0.1% (w/w) Polysorbate 80 (JT Baker) and 0.5%
(w/w) high viscosity carboxymethyl cellulose sodium (Spectrum) to
achieve a final 10 ml/kg dosing (oral gavage).
[0327] A stock tumor was established by subcutaneously injecting a
cell suspension into nude mice. The resulting tumor was maintained
in nude mice subcutaneously as tumor stock prior to use. Tumor
implantation was performed when the stock tumors were in log phase
of growth. Before implantation, tumor tissue was harvested from
stock mice and placed in RPMI-1640 medium. Necrotic tissues were
dissected away and viable tissues were cut into 1-2 mm.sup.2
pieces. In these experiments, 1.times.10.sup.7 H-460 tumor cells
were implanted subcutaneously to the flanks of female Harlan nude
mice.
[0328] Treatment (administration of compounds of the present
invention) was initiated when the inoculated tumors reached
approximately 100 mm.sup.3, and continued for four weeks.
[0329] These studies followed the guidelines of the Tumor Growth
Delay (TGD) type, using a protocol that required individual animals
to be humanely euthanized after reaching a set endpoint of tumor
volume greater than or equal to 2 cc. At this endpoint, blood was
also sampled and hematocrit (HCT) was determined.
[0330] Animals were administered Compound A (60 mg/kg) with or
without additional administration of one of the chemotherapeutic
agents paclitaxel or carboplatin. These two chemotherapeutic are
representative of two broad classes of conventional anti-tumor
therapeutics: microtubule poisons (Paclitaxcel); and DNA-directed
agents, including the sub-classification of DNA alkylating agents
(Carboplatin). In tumor-bearing human patients, conventional
anti-tumor therapy commonly use one or both classes of
chemotherapeutic agents.
[0331] Combined treatment groups (i.e., treatment with both
Paclitaxel and Compound A or treatment with both Carboplatin and
Compound A) were administered compound of the present invention and
chemotherapeutic agents on different days. The study was initiated
with administration of the chemotherapeutic agent or vehicle
control, and followed one day later with administration of Compound
A or vehicle control. Treatment was continued over a course of 62
days. (See Table 1 and Table 2 for compound and chemotherapeutic
agent dosing schedule.)

[0332] Administration of chemotherapeutic agents is associated with
toxicity and premature morbidity. The Carboplatin treatment
schedule used in these studies was excessive. Premature morbidity
was observed in Carboplatin treatment groups only. (See Table 3.)
When Carboplatin administration was combined with administration of
Compound A, an improvement in morbidity was observed, as shown in
Table 3. These results indicated that compounds and methods of the
present invention are useful for reducing toxic effects of
chemotherapy, including premature morbidity.

[0333] Administration of chemotherapeutic agents is also associated
with the development of anemia. As shown in FIG. 2, animals
administered Carboplatin displayed a significant decrease in
hematocrit over time (closed circles in FIG. 2), indicative of
anemia induced by chemotherapy administration. Administration of
Carboplatin and Compound A resulted in a reduction of the extent of
decrease in hematocrit compared to the decrease in hematocrit
observed in animals administered Carboplatin alone (open circles in
FIG. 2).
[0334] These results demonstrated that methods and compounds of the
present invention were effective at treating chemotherapy-induced
anemia.
Example 3
Compounds and Methods of the Invention Limit Weight Loss Associated
with Chemotherapy
[0335] To examine the effects of compounds and methods of the
present invention on weight loss associated with chemotherapeutic
agents, the following study was performed. This experiment was
carried out essentially as described above in Example 2. The human
H-460 lung cancer cell line used was obtained from the National
Cancer Institute. (Brower et al., (1986) Cancer Res 46:798-806.)
Animals were maintained in a HEPA-filtered environment during the
experimental period. Cages, food, and bedding were autoclaved.
Animal diets were obtained from Harlan Teklad (Madison, Wis.).
Hydrochloric acid, 0.15% (v/v), was added to the drinking
water.
[0336] Compounds of the invention were pre-formulated in an aqueous
vehicle consisting of 0.1% (w/w) Polysorbate 80 (JT Baker) and 0.5%
(w/w) high viscosity carboxymethyl cellulose sodium (Spectrum) to
achieve a final 10 ml/kg dosing (oral gavage).
[0337] A stock tumor was established by subcutaneously injecting a
cell suspension into nude mice. The resulting tumor was maintained
in nude mice subcutaneously as tumor stock prior to use. Tumor
implantation was performed when the stock tumors were in log phase
of growth. Before implantation, tumor tissue was harvested from
stock mice and placed in RPMI-1640 medium. Necrotic tissues were
dissected away and viable tissues were cut into 1-2 mm.sup.2
pieces. In these experiments, 1.times.10.sup.7 H-460 tumor cells
were implanted subcutaneously to the flanks of female Harlan nude
mice.
[0338] Treatment (administration of compounds of the present
invention) was initiated when the inoculated tumors reached
approximately 100 mm.sup.3, and continued for four weeks.
[0339] Animals were administered Compound A (60 mg/kg) with or
without additional administration of one of the chemotherapeutic
agents paclitaxel or carboplatin. These two chemotherapeutic are
representative of two broad classes of conventional anti-tumor
therapeutics: microtubule poisons (Paclitaxcel); and DNA-directed
agents, including the sub-classification of DNA alkylating agents
(Carboplatin). In tumor-bearing human patients, conventional
anti-tumor therapy commonly use of one or both classes of
chemotherapeutic agents.
[0340] Body weights were monitored over time for individual
animals. Changes in individual animal body weights over time are
shown in FIGS. 3-8, and are presented as percent of initial body
weight (treatment day 1), which was set at 100%.
[0341] As shown in FIG. 3 and FIG. 4, body weights of animals
administered vehicle control (FIG. 3) or Compound A (FIG. 4)
increased gradually during the time course of the study. All
animals administered either vehicle control or Compound A ended the
study with an overall net weight gain.
[0342] Animals administered either chemotherapeutic agent
(Paclitaxel or Carboplatin) displayed a pattern of weight loss
compared to that of non-treated vehicle control animals. (Compare
FIG. 3 (vehicle) with FIG. 5 (Paclitaxel); compare FIG. 3 (vehicle)
with FIG. 7 (Carboplatin). In addition, not only did administration
of either chemotherapeutic agent limit or reduce weight gain (e.g.,
limit or reduce growth) in animals, a number of animals treated
with either chemotherapeutic agent ended the study with body
weights below their respective starting body weights. These results
indicated that, in addition to being associated with the
development of anemia, administration of chemotherapeutic agents
was associated with weight loss and reduced growth.
[0343] In animals administered either chemotherapeutic agent in
combination with Compound A, the weight loss associated with
chemotherapy administration was reduced. Following administration
of Paclitaxel and Compound A (FIG. 6), fewer animals showed weight
loss compared to that of animals administered Paclitaxel alone
(FIG. 5). Additionally, administration of Paclitaxel and Compound A
resulted in a higher number of animals which either maintained body
weight or showed an increase in body weight compared to that in
animals administered Paclitaxel alone. (Compare FIG. 5 and FIG. 6.)
In particular, 4 or 10 animals in the combined Paclitaxel and
Compound A treatment group ended the study at a body weight below
that at the start of the study, compared to only 2 of 10 animals in
the Paclitaxel alone treatment group. Additionally, administration
of paclitaxel and Compound A resulted in a delay in the initial
(early) weight loss in animals compared to that on animals
administered Paclitaxel alone. (Compare weight loss patterns from
day 0 to day 20 in FIG. 5 and FIG. 6.)
[0344] Similar results were observed in animals administered
Carboplatin and Compound A. Following administration of Carboplatin
and Compound A (FIG. 8), fewer animals showed weight loss compared
to that of animals administered Carboplatin alone (FIG. 7). In
particular, 7 of 10 animals in the Carboplatin alone treatment
group ended the study below starting weights, and only 3 of 10
animals in this group had more than a 10% weight gain at any time
during the study. In contrast, when Carboplatin was combined with
Compound A administration, animals showed substantially less severe
weight loss compared to animals administered Carboplatin alone. In
particular, 6 of 10 animals in the Carboplatin and Compound A
treatment group ended the study below starting weights, and 7 of 10
animals in this treatment group had a 10% or greater weight gain
during the course of the study. Additionally, premature morbidity
in the Carboplatin treatment groups was observed and was correlated
with weight loss (data not shown). All animals in this treatment
group dropped below starting weights.
[0345] Thus, compounds and methods of the invention can be used to
suppress weight loss associated with treatment with carboplatin.
The observation of a beneficial suppression of body weight loss
with known cancer chemotherapeutics of diverse mechanism of action
indicates the broad utility of the present invention with respect
to combined treatment regimens.
[0346] Various modifications of the invention, in addition to those
shown and described herein, will become apparent to those skilled
in the art from the foregoing description. Such modifications are
intended to fall within the scope of the appended claims.
