TECHNICAL FIELD
[0002] The present invention relates to MIC-1 compounds and their
pharmaceutical use.
INCORPORATION-BY-REFERENCE OF THE SEQUENCE LISTING
[0003] The Sequence Listing, entitled
"160031US02_Sequence_Listing_ST25", is 142,965 bytes, was created
on Feb. 23, 2021 and is incorporated herein by reference.
BACKGROUND OF INVENTION
[0004] Macrophage Inhibitory Cytokine-1 (MIC-1) was first described
in 1997 (Bootcov et al, Proc. Natl. Acad. Sci. October 1997) based
on experiments showing increased expression in activated
macrophages. MIC-1 has subsequently been identified by others and
given several additional names such as placental transforming
growth factor beta (PTGF-.beta.), placental bone morphogenetic
protein, growth differentiation factor-15 (GDF15), prostate derived
factor (PDF), non-steroidal anti-inflammatory drug-activated gene
(NAG-1) and PL74.
[0005] MIC-1 is a distant member of the TGF-beta super family, a
family of peptide hormones involved in cell growth and
differentiation. MIC-1 circulates as a cysteine-rich homodimer with
a molecular mass of 24.5 kDa. MIC-1 was initially reported to be
up-regulated in macrophages by stimuli including IL-1b, TNF-alpha,
IL-2, and TGF-b. It was also shown that MIC-1 could reduce
lipopolysaccharide-induced TNF-alpha production and it was based on
these data proposed that MIC-1 was an anti-inflammatory
cytokine.
[0006] More recently, (Johnen et al, Nat Med., November, 2007) data
from patients with advanced cancer showed that weight loss
correlated with circulating levels of MIC-1. These data indicates
that MIC-1 regulates body weight. This hypothesis was tested in
mice xenografted with prostate tumor cells, where elevated MIC-1
levels were associated with loss of body weight and decreased food
intake, an effect which could be reversed by administration of
neutralising antibodies against MIC-1. As administration of
recombinant MIC-1 to mice regulated hypothalamic neuropeptide Y and
pro-opiomelanocortin it was proposed that MIC-1 regulates food
intake by a central mechanism. Furthermore, transgenic mice
overexpressing MIC-1 are gaining less weight and body fat both on a
normal low fat diet and on a high fat diet (Macia et al, PLoS One,
April, 2012). Also, transgenic mice overexpressing MIC-1 fed both
on a low and high fat diet, respectively, had improved glucose
tolerance compared with wild type animals on a comparable diet.
[0007] Obesity is most commonly caused by excessive calorie intake
alone or in conjunction with decreased energy expenditure and/or
lack of physical exercise. Obesity is a well-established risk
factor for metabolic diseases like diabetes, cardiovascular
diseases, sleep apnea and cancer.

DETAILED DESCRIPTION
[0040] The invention relates to a MIC-1 compound comprising a MIC-1
polypeptide. In one aspect, the invention relates to a MIC-1
compound comprising a MIC-1 polypeptide and an N-terminal amino
acid extension, wherein said extension consists of 3 to 200 amino
acid residues and where the compound has a calculated pI lower than
6.5.
MIC-1
[0041] The term "MIC-1" as used herein means Macrophage Inhibitory
Cytokine-1 (MIC-1), also known as Growth Differentiation Factor 15
(GDF-15), placental bone morphogenetic protein (PLAB) and
nonsteroidal anti-inflammatory drug-activated gene (NAG-1). MIC-1
is synthesized as a 62 kDa intracellular homodimer precursor
protein which subsequently is cleaved by a furin-like protease into
a 24.5 kDa homodimer. The sequence of the full length wild type
human MIC-1 is available from the UNIPROT database with accession
no. Q99988. The 308 amino acid precursor sequence includes a signal
peptide (amino acids 1-29), a propeptide (amino acids 30-196) and a
MIC-1 monomer sequence (amino acids 197-308). The 112 amino acid
MIC-1 monomer sequence is included herein as SEQ ID NO:1. MIC-1
monomer contains nine cysteine residues which give rise to the
formation of 4 intrachain disulphide bonds and one interchain
disulphide bond to create a covalently linked 24.5 kDa homodimer. A
naturally occurring mutation corresponding to H6D in the MIC-1
monomer sequence (SEQ ID NO:1) has been described.
[0042] The term "MIC-1 compound", as used herein, refers to a
compound comprising a MIC-1 polypeptide and an N-terminal amino
acid extension. The MIC-1 compound is typically in the form of a
homodimer.
[0043] The term "MIC-1 polypeptide" as used herein refers to the
human MIC-1 monomer sequence of SEQ ID NO:1 or an analogue thereof.
Numerical references to particular MIC-1 residues, if not stated
otherwise, refer to the 112 amino acid monomer sequence (i.e.,
residue 1 is Alanine (A1), and residue 112 is Isoleucine
(I112).
[0044] The term "MIC-1 analogue", or "analogue of MIC-1" as used
herein refers to a MIC-1 polypeptide, which is an amino acid
variant of the monomer MIC-1 sequence of SEQ ID NO:1. In other
words, a MIC-1 analogue is a MIC-1 polypeptide in which a number of
amino acid residues have been changed when compared to human MIC-1
(SEQ ID NO: 1). These changes may represent, independently, one or
more amino acid substitutions, additions, and/or deletions.
[0045] MIC-1 analogues may be described by reference to the amino
acid residue which is changed, the number of the amino acid residue
(i.e. the corresponding position in the MIC-1 monomer sequence (SEQ
ID NO:1)), and the change (e.g. the amino acid residue change
to).
[0046] In one aspect, the MIC-1 analogue is a functional variant of
the MIC-1 of SEQ ID NO:1. In one aspect of the invention, the MIC-1
analogues display at least 85%, 90% or 95% sequence identity to
MIC-1 of SEQ ID NO:1. As an example of a method for determination
of the sequence identity between two analogues the two peptides H6D
MIC-1 and MIC-1 of SEQ ID NO:1 are aligned. The sequence identity
of the H6D MIC-1 analogue relative to MIC-1 of SEQ ID NO:1 is given
by the number of aligned identical residues minus the number of
different residues divided by the total number of residues in MIC-1
of SEQ ID NO:1. Accordingly, in said example the sequence identity
in percentage is (112-1)/112.times.100. In the determination of the
sequence identity of a MIC-1 analogue, the N-terminal amino acid
extension is not included.
[0047] In another aspect of the invention, the MIC-1 analogues
comprise less than for example less than 15, 10 or 5, amino acid
modifications (substitutions, deletions, additions (including
insertions) and any combination thereof) relative to human MIC-1 of
SEQ ID NO:1. The term "amino acid modification" used throughout
this application is used in the meaning of a modification to an
amino acid as compared to monomer MIC-1 (SEQ ID NO:1). This
modification can be the result of a deletion of an amino acid,
addition of an amino acid, substitution of one amino acid with
another or a substituent covalently attached to an amino acid of
the peptide.
[0048] Substitutions: In one aspect amino acids may be substituted
by conservative substitution. The term "conservative substitution"
as used herein denotes that one or more amino acids are replaced by
another, biologically similar residue. Examples include
substitution of amino acid residues with similar characteristics,
e.g. small amino acids, acidic amino acids, polar amino acids,
basic amino acids, hydrophobic amino acids and aromatic amino
acids.
[0049] In one aspect amino acids may be substituted by
non-conservative substitution. The term "non-conservative
substitution" as used herein denotes that one or more amino acids
are replaced by another amino acid having different
characteristics. Examples include substitution of a basic amino
acid residue with an acidic amino acid residue, substitution of a
polar amino acid residue with an aromatic amino acid residue, etc.
In one aspect, the non-conservative substitution is substitution of
a coded amino acid to another coded amino acid having different
characteristics. In one aspect, the MIC-1 analogues may comprise
substitutions of one or more unnatural and/or non-amino acids,
e.g., amino acid mimetics, into the sequence of MIC-1.
[0050] The asparagine residue in position 3 (N3) of human MIC-1
monomer sequence (SEQ ID NO:1) is chemically labile. In one aspect
of the invention, the asparagine in the position corresponding to
position 3 of monomer MIC-1 sequence (SEQ ID NO:1) may be
substituted to Serine (N3S), Glutamic acid (N3E), Alanine (N3A), or
Glutamine (N3Q). In one aspect of the invention, the asparagine in
the position corresponding to position 3 of human MIC-1 monomer
sequence (SEQ ID NO:1) has been substituted to Glutamic acid
(N3E).
[0051] In one aspect of the invention, the arginine in the position
corresponding to position 2 of human MIC-1 monomer sequence (SEQ ID
NO:1) has been substituted to alanine (R2A), and the asparagine in
the position corresponding to position 3 of human MIC-1 monomer
sequence (SEQ ID NO:1) has been substituted to Glutamic acid
(N3E).
[0052] Deletions and Truncations: In one aspect, the MIC-1
analogues of the invention may have one or more amino acid residues
deleted from the amino acid sequence of MIC-1 (SEQ ID NO:1), alone
or in combination with one or more insertions or substitutions.
[0053] MIC-1 analogues with amino acid deletions may be described
by "des", reference to the amino acid residue which is deleted, and
followed by the number of the deleted amino acid (i.e. the
corresponding position in the monomer MIC-1 (SEQ ID NO:1)). In some
embodiments of the invention, the asparagine in the position
corresponding to position 3 of human monomer MIC-1 (SEQ ID NO:1) is
deleted (MIC-1 des-N3, SEQ ID NO:2).
[0054] MIC-1 analogues with a truncation of one or more amino acid
residues at the N or C terminal may be described by "MIC-1-.DELTA."
and reference to the number(s) of the deleted amino acid residues
(i.e. the corresponding position in the monomer MIC-1 (SEQ ID
NO:1)). In some embodiments of the invention, the first three
residues (A1, R2, N3) at the N terminal are deleted
(MIC-1-.DELTA.1-3, SEQ ID NO:3).
[0055] Insertions: In one aspect, the MIC-1 analogues of the
invention may have one or more amino acid residues inserted into
the amino acid sequence of human MIC-1, alone or in combination
with one or more deletions and/or substitutions.
[0056] In one aspect, the MIC-1 analogues of the invention may
include insertions of one or more unnatural amino acids and/or
non-amino acids into the sequence of MIC-1.
[0057] The term "protein" or "polypeptide", as e.g. used herein,
refers to a compound which comprises a series of amino acids
interconnected by amide (or peptide) bonds.
[0058] Amino acids are molecules containing an amine group and a
carboxylic acid group, and, optionally, one or more additional
groups, often referred to as a side chain.
[0059] The term "amino acid" includes coded (or proteinogenic or
natural) amino acids (amongst those the 20 standard amino acids),
as well as non-coded (or non-proteinogenic or non-natural) amino
acids. Coded amino acids are those which are naturally incorporated
into proteins. The standard amino acids are those encoded by the
genetic code. Non-coded amino acids are either not found in
proteins, or not produced by standard cellular machinery (e.g.,
they may have been subject to post-translational modification). In
what follows, all amino acids of the MIC-1 proteins for which the
optical isomer is not stated is to be understood to mean the
L-isomer (unless otherwise specified).
[0060] As is apparent from the above, amino acid residues may be
identified by their full name, their one-letter code, and/or their
three-letter code. These three ways are fully equivalent. For the
reader's convenience, the single and three letter amino acid codes
are provided below:
[0061] Glycine: G and Gly; Proline: P and Pro; Alanine: A and Ala;
Valine: V and Val; Leucine: L and Leu; Isoleucine: I and Ile;
Methionine: M and Met; Cysteine: C and Cys; Phenylalanine: F and
Phe; Tyrosine: Y and Tyr; Tryptophan: W and Trp; Histidine: H and
His; Lysine: K and Lys; Arginine: R and Arg; Glutamine: Q and Gin;
Asparagine: N and Asn; Glutamic Acid: E and Glu; Aspartic Acid: D
and Asp; Serine: S and Ser; and Threonine: T and Thr.
N-Terminal Amino Acid Extension
[0062] In some embodiments of the invention the MIC-1 compound
comprises an N-terminal amino acid extension.
[0063] The term "N-terminal amino acid extension" as used herein,
means that the N-terminal of the MIC-1 polypeptide is attached to
the C-terminal of the N-terminal amino acid extension via an amide
bond, preferably a peptide bond. The terms "N-terminal amino acid
extension", "N-terminal extension", and "N-extension" herein means
the same thing and are used interchangeably. In one embodiment, the
compound of the invention comprises human MIC-1 monomer sequence
(SEQ ID NO:1) with an amino acid extension attached at the
N-terminal, i.e. the Alanine at positon 1 (A1) via a peptide
bond.
[0064] In some embodiments of the invention, the N-terminal amino
acid extension is up to 200 amino acid residues long. In a
particular embodiment of the invention the N-terminal amino acid
extension has from 3 to 36 amino acid residues.
[0065] In one aspect of the invention, the N-terminal amino acid
extension has a surplus of acidic amino acid residues (Aspartic
acid and Glutamic acid) of at least 3, 4, 5 or 6 compared to the
number of basic amino acid residues (Lysine, Arginine and
Histidine). A "surplus" of acidic amino acid residues means that
the number of acidic residues exceeds the number of basic residues.
A defined value of the surplus of acidic amino acid residues is
calculated as the number of acidic residues minus the number of
basic residues.
[0066] Methionine is the initial amino acid for protein expression
in prokaryotic cells (e.g. bacteria, for instance, E. coli). In
some embodiments of the invention, the initial Methionine is
removed from the protein during the protein expression. Therefore,
the initial Methionine is not included in the sequence of the
N-extension of MIC-1 compound. However, a person skilled in the art
knows that the start codon, coding the initial Methionine, is
required for the protein translation initiation and should be
incorporated right in front of the nucleotide sequence for protein
expression without exception.
[0067] Meanwhile, it can be understood that those MIC-1 compounds
with N-extensions having the initial Methionine also fall into the
scope of the invention.
Isoelectric Point (pI)
[0068] The calculated pI of a MIC-1 compound is defined as the pH
at which the net calculated charge of the compound is zero. The
calculated charge of the MIC-1 compound as a function of pH is
obtained using the pKa values of the amino acid residues described
in Table 1 and the method described by B. Skoog and A. Wichman
(Trends in Analytical Chemistry, 1986, vol. 5, pp. 82-83). The side
chain pKa of cysteine (Cys) is only included in the charge
calculation for cysteines with a free sulfhydryl group. As an
example the calculated pI value of human wtMIC-1 is 8.8 as the
homodimer.
[0069] As described herein, pI calculations on MIC-1 compounds are
made on MIC-1 compounds as homodimers.
TABLE-US-00001 TABLE 1 pKa of amino acid residues used for
calculating pI. The pKa values are those described in "Correlation
of Electrophoretic Mobilities from Capillary Electrophoresis with

[0070] In one aspect, the MIC-1 compounds of the invention have
good biophysical properties. These properties include but are not
limited to solubility and/or stability.
Solubility
[0071] The human wild type MIC-1 is a hydrophobic protein, with a
calculated pI 8.8 based on the homodimer. Consequently, wild type
MIC-1 can only be solubilized to around 0.5 mg/ml in neutral pH
aqueous buffer systems. The low solubility of MIC-1 significantly
hampers its formulation properties and therapeutic use, so
developing a solubility-engineered MIC-1 compound is important for
MIC-1 molecular engineering.
[0072] In one aspect, the compounds of the invention have improved
solubility (i.e. are more soluble) relative to human MIC-1 of SEQ
ID NO:1.
[0073] As described herein, solubility is measured as described in
Example 4.
[0074] In certain embodiments, the MIC-1 compounds of the invention
have a solubility of at least 1 mg/ml in Tris buffer at pH 8.0. In
other embodiments, the compounds of the invention have a solubility
of at least 5 mg/ml, at least 10 mg/ml, at least 30 mg/ml, or at
least 40 mg/ml in Tris buffer at pH 8.0.
[0075] As described herein, solubility is measured on MIC-1
compounds as homodimers.
Stability
[0076] The human wild type MIC-1 sequence is a chemically instable
and several residues of the amino acid sequence could be modified
during storage, including deamidation on Asparagine at position 3
(N3) and oxidation of methionines M43, M57 and M86. Chemical
instability of certain residues could impact pharmaceutical
properties so developing chemical stable MIC-1 compounds would be
another important part of making a MIC-1 therapeutic compound.
[0077] In one aspect, the compounds of the invention have improved
chemical stability relative to human MIC-1 of SEQ ID NO:1.
[0078] The term "chemical stability" refers to chemical changes in
the polypeptide structure leading to formation of chemical
degradation products potentially having a reduced biological
activity, decreased solubility, and/or increased immunogenic effect
as compared to the intact polypeptide. The chemical stability can
be evaluated by measuring the amount of chemical degradation
products at various time-points after exposure to different
environmental conditions, e.g. by SEC-HPLC, and/or RP-HPLC.
[0079] MIC-1 may be chemically instable; and several residues, of
the amino acid sequence (SEQ ID NO:1) could be modified during
storage, including deamidation of N3 and oxidation of the
methionines M43, M57 and M86. Chemical instability of certain
residues could impact pharmaceutical properties like low chemical
stability for MIC-1 as a therapeutic compound.
[0080] In certain embodiments of the invention, certain residues of
the MIC-1 monomer sequence (SEQ ID NO:1) is modified, e.g. by
substitution to increase the chemical stability of the MIC-1
compounds. To avoid deamidation, N3 could be deleted or substituted
with other amino acids, e.g. E or Q. To decrease oxidation,
Methionine could be substituted with other amino acids, e.g. E or
L.
Crystallisation
[0081] In one aspect, the compounds of the invention are showing
reduced crystal forming tendency at pH 8.0 compared with MIC-1 of
SEQ ID NO:1.
Immunogenicity
[0082] In one aspect, the compounds of the invention have low
immunogenicity risk.
In Vitro Activity
[0083] In one aspect, the compounds of the invention have retained
MIC-1 receptor potency relative to human MIC-1 (SEQ ID NO:1).
Receptor potency and efficacy can be measured in mammalian cells
transfected with human MIC-1 receptor (hGFRAL, GDNF family receptor
alpha like) and its signalling co-receptor hRET51 (proto-oncogene
tyrosine-protein kinase receptor Ret isoform 51). MIC-1 compounds
activation of the receptor complex is measured by phosphorylation
of extracellular signal-regulated kinases (ERKs) as described in
Example 6.
[0084] As described herein receptor potency and efficacy is
measured on MIC-1 compounds as homodimers.
In Vivo Biological Activity
[0085] In one aspect the compounds of the invention are potent in
vivo, which may be determined as is known in the art in any
suitable animal model.
[0086] The non-obese Sprague Dawley rat is one example of a
suitable animal model, and the changes in food intake may be
determined in such rats in vivo, e.g. as described in Example 7. In
one aspect the compounds of the invention inhibits in vivo food
intake in non-obese Sprague Dawley rats. Diet-Induced Obese (DIO)
Sprague Dawley rats is another example of a suitable animal model,
and the changes in food intake may be determined in such rats in
vivo, In one aspect the compounds of the invention inhibits in vivo
food intake and lowers body weight in DIO Sprague Dawley rats.
Production Processes
[0087] MIC-1 compounds of the present invention may be produced by
means of recombinant protein technology known to persons skilled in
the art. In general, nucleic acid sequences encoding the proteins
of interest or functional variants thereof are modified to encode
the desired MIC-1 compound. This modified sequence is then inserted
into an expression vector, which is in turn transformed or
transfected into the expression host cells.
[0088] The nucleic acid construct encoding the MIC-1 compound may
suitably be of genomic, cDNA or synthetic origin. Amino acid
sequence alterations are accomplished by modification of the
genetic code by well-known techniques.
[0089] The DNA sequence encoding the MIC-1 compound is usually
inserted into a recombinant vector which may be any vector, which
may conveniently be subjected to recombinant DNA procedures, and
the choice of vector will often depend on the host cell into which
it is to be introduced. Thus, the vector may be an autonomously
replicating vector, i.e. a vector, which exists as an
extrachromosomal entity, the replication of which is independent of
chromosomal replication, e.g. a plasmid. Alternatively, the vector
may be one which, when introduced into a host cell, is integrated
into the host cell genome and replicated together with the
chromosome(s) into which it has been integrated.
[0090] The vector is preferably an expression vector in which the
DNA sequence encoding the MIC-1 compound is operably linked to
additional segments required for transcription of the DNA. The
term, "operably linked" indicates that the segments are arranged so
that they function in concert for their intended purposes, e.g.
transcription initiates in a promoter and proceeds through the DNA
sequence coding for the polypeptide until it terminates within a
terminator.
[0091] Thus, expression vectors for use in expressing the MIC-1
compound will comprise a promoter capable of initiating and
directing the transcription of a cloned gene or cDNA. The promoter
may be any DNA sequence, which shows transcriptional activity in
the host cell of choice and may be derived from genes encoding
proteins either homologous or heterologous to the host cell.
[0092] Additionally, expression vectors for expression of the MIC-1
compound will also comprise a terminator sequence, a sequence
recognized by a host cell to terminate transcription. The
terminator sequence is operably linked to the 3' terminus of the
nucleic acid sequence encoding the polypeptide. Any terminator
which is functional in the host cell of choice may be used in the
present invention.
[0093] Expression of the MIC-1 compound can be aimed for either
intracellular expression in the cytosol of the host cell or be
directed into the secretory pathway for extracellular expression
into the growth medium.
[0094] Intracellular expression is the default pathway and requires
an expression vector with a DNA sequence comprising a promoter
followed by the DNA sequence encoding the MIC-1 compound followed
by a terminator.
[0095] To direct the sequence of the MIC-1 compound into the
secretory pathway of the host cells, a secretory signal sequence
(also known as signal peptide or a pre sequence) is needed as an
extension of the MIC-1 sequence. A DNA sequence encoding the signal
peptide is joined to the 5' end of the DNA sequence encoding the
MIC-1 compound in the correct reading frame. The signal peptide may
be that normally associated with the protein or may be from a gene
encoding another secreted protein.
[0096] The procedures used to ligate the DNA sequences coding for
the MIC-1 compound, the promoter, the terminator and/or secretory
signal sequence, respectively, and to insert them into suitable
vectors containing the information necessary for replication, are
well known to persons skilled in the art (cf., for instance,
Sambrook et al., Molecular Cloning: A Laboratory Manual, Cold
Spring Harbor, N.Y., 1989).
[0097] The host cell into which the DNA sequence encoding the MIC-1
compound is introduced may be any cell that is capable of
expressing the MIC-1 compound either intracellularly or
extracellularly. The MIC-1 compound may be produced by culturing a
host cell containing a DNA sequence encoding the MIC-1 compound and
capable of expressing the MIC-1 compound in a suitable nutrient
medium under conditions permitting the expression of the MIC-1
compound. Non-limiting examples of host cells suitable for
expression of MIC-1 compounds are: Escherichia coli, Saccharomyces
cerevisiae, as well as human embryonic kidney (HEK), Baby Hamster
Kidney (BHK) or Chinese hamster ovary (CHO) cell lines. If
posttranslational modifications are needed, suitable host cells
include yeast, fungi, insects and higher eukaryotic cells such as
mammalian cells.
[0098] Once the MIC-1 compound has been expressed in a host
organism it may be recovered and purified to the required quality
by conventional techniques. Non-limiting examples of such
conventional recovery and purification techniques are
centrifugation, solubilization, filtration, precipitation,
ion-exchange chromatography, immobilized metal affinity
chromatography (IMAC), Reversed phase-High Performance Liquid
Chromatography (RP-HPLC), gel-filtration and freeze drying.
[0099] Examples of recombinant expression and purification of MIC-1
proteins may be found in e.g. Cordingley et al., J. Virol. 1989,
63, pp 5037-5045; Birch et al., Protein Expr Purif., 1995, 6, pp
609-618 and in WO2008/043847. Examples of microbial expression and
purification of MIC-1 proteins may be found in e.g. Chich et al,
Anal. Biochem, 1995, 224, pp 245-249 and Xin et al., Protein Expr.
Purif. 2002, 24, pp 530-538.
[0100] Specific examples of methods of preparing a number of the
compounds of the invention are included in the experimental
part.
Inclusion Body and Protein Expression
[0101] MIC-1 compounds can be expressed in bacteria such as E.
coli. In the context of the present invention, large scale protein
production of said MIC-1 polypeptides with an N-extension could
take of using Inclusion Bodies (IB) as this represent an
advantageous approach to controlling process recovery, protein
purity, protease degradation and general protein stability. This
becomes particular important for large scale protein production. Of
critical importance for the quality of IB is the balance of MIC-1
polypeptides with an N-extension solubility partly controlled by
the calculated pI and IB formation.
Mode of Administration
[0102] The term "treatment" is meant to include both the prevention
and minimization of the referenced disease, disorder, or condition
(i.e., "treatment" refers to both prophylactic and therapeutic
administration of a compound of the invention or composition
comprising a compound of the invention unless otherwise indicated
or clearly contradicted by context.
[0103] The route of administration may be any route which
effectively transports a compound of this invention to the desired

example, subcutaneously, intramuscularly or intraveneously.
Alternatively, a compound of this invention can be administered
orally, pulmonary, rectally, transdermally, buccally, sublingually,
or nasally.
[0104] The amount of a compound of this invention to be
administered, the determination of how frequently to administer a
compound of this invention, and the election of which compound or
compounds of this invention to administer, optionally together with
another pharmaceutically active agent, is decided in consultation
with a practitioner who is familiar with the treatment of obesity
and related disorders.

[0105] Pharmaceutical compositions comprising a compound of the
invention or a pharmaceutically acceptable salt, amide, or ester
thereof, and a pharmaceutically acceptable excipient may be
prepared as is known in the art.
[0106] The term "excipient" broadly refers to any component other
than the active therapeutic ingredient(s). The excipient may be an
inert substance, an inactive substance, and/or a not medicinally
active substance.
[0107] The excipient may serve various purposes, e.g. as a carrier,

Design of MIC-1 Compounds
[0130] In an aspect of the invention, MIC-1 compounds were designed
to have increased solubility. In an aspect of the invention, this
was achieved by adding an N-terminal "acidic" extension to the
MIC-1 polypeptide. In an aspect of the invention, solubility were
enhanced and stability improved by modification of the amino acid
sequence of the MIC-1 polypeptide. For example extensions were
added to the N terminal of a MIC-1 polypeptide, and/or modification
was done within the amino acid sequence of the MIC-1 polypeptide
(in-sequence mutation).
N-Extension Design:
[0131] In the design of the N-terminal amino acid_extension, F, I,
L, M, V, W and Y were excluded, since they could contribute to
protein aggregation. H, K, and R were also excluded, since they
could cause undesired binding on cell membrane. A, E, G, P, S, T,
D, N, and Q are preferred for the N-extension sequence. E and D are
particularly preferred since they increase the solubility by
decreasing pI value of the compound. Particularly, for some
N-extensions, one or two additional Alanine(s) were added at the
very N-terminal to increase the initial Methionine removing
efficiency when MIC-1 compounds were expressed in E. coli.
[0132] Various N-terminal amino acid_extensions were designed based
on the above principles. Some N-extensions comprise sequences
originating from human proteins (humanized sequences); some
comprise artificially designed sequence(s) (e.g. GS, SG, AEE, AES,
GEPQ (SEQ ID NO:123), GEPS (SEQ ID NO:118)); some comprise several
repeats of the humanized sequences or artificial sequences; some
comprise a combination of the above. Several 6-residue sequences
(6-mers) were designed. N-extensions could comprise one or more of
a 6-mers, part of a 6-mers (e.g., 1-5 residues of a 6-mers), or a
combination of the above. The amino acid residues of the artificial
sequences (including 6-mers) and the humanized sequences could be
arranged in any order.
[0133] Some representative 6-mers and combinations of 6-mers are

In-Sequence Mutations:
[0134] Certain internal residues of MIC-1 (SEQ ID NO:1) were
modified, e.g. by substitution. For example, to increase the
solubility of MIC-1 compounds, a hydrophobic residue of MIC-1 could
be substituted with a hydrophilic residue, preferably by with an
acidic residue; a positive charged residue could be substituted
with an acidic residue, etc. To decrease oxidation, methionine
could be substituted with other amino acids, e.g. E, F or L.
[0135] In-sequence mutations for increasing solubility include but
are not limited to: P11E, H18E, R21E, A30E, A47E, R53E, A54E, M57E,

N3G, N3V, N3H, N3Y and N3Q.
pI Calculation of MIC-1 Compounds
[0138] The calculated pI of a MIC-1 compound is defined as the pH
at which the net calculated charge of the compound is zero. The
calculated charge of the MIC-1 compound as a function of pH is
obtained using the pKa values of the amino acid residues described
in Table 1 and the method described by B. Skoog and A. Wichman
(Trends in Analytical Chemistry, 1986, vol. 5, pp. 82-83). The side
chain pKa of cysteine (Cys) is only included in the charge
calculation for cysteines with a free sulfhydryl group. As an
example the calculated pI value of human wtMIC-1 is 8.8 as the
homodimer.
[0139] Herein, and throughout this document, pI calculations on
MIC-1 compounds, if not stated otherwise, are made on MIC-1
compounds as homodimers.

Materials and Methods
General Methods of Preparation
Example-1: Expression and Fermentation of the MIC-1 Compounds
[0140] The cDNA of MIC-1 compound was sub-cloned into a pET11b
derived vector. Overexpression of MIC-1 compounds as inclusion
bodies was induced in E. coli by 0.5 mM isopropyl
.beta.-d-thiogalactoside (IPTG) when the cell density reached an
OD600 of 1.0. After continuous growth in TB for 20 h at 37.degree.
C., the cells were harvested and samples for both LC/MS and UPLC
were prepared to confirm the molecular weight.
[0141] Fermentation was carried out on fed-batch process in
chemical defined medium as supplement. Fermentation yield largely
depended on different compounds, which varied from 1 g/L to 8 g/L
from compound to compound.
Example-2: Purification and Refolding
[0142] The MIC-1 compounds were further purified as follows:
Slurry (20% w/v) of E. coli in 10 mM Tris buffer pH 8.0 was
sonicated (3 seconds on/off intervals on ice for 5 minutes) and the
MIC-1 compounds was pelleted by centrifugation (10,000.times.g, for
30 minutes). The inclusion bodies were re-solubilised by 8 M urea
in 20 mM Tris pH 8.0, and debris removed by centrifugation
(10,000.times.g, for 30 minutes). The MIC-1 compounds in the
resulting supernatant was collected and diluted into the refolding
buffer (50 mM Tris, pH 8.5 and 10% DMF or 10% DMSO) to the final
concentration of 0.1 mg/ml. The refolding process lasted for 48
hours in the cold room. The resulting solution was filtered by 0.4
.mu.m filter and loaded onto Hydrophobic Interaction column or
anion exchange chromatography (50 mM Tris pH 8.0, 0-500 mM NaCl)
using Q Sepharose Fast Flow resin (GE Healthcare), as generally
described in Protein Purification. Principles and Practice Series:
Springer Advanced Texts in Chemistry Scopes, Robert K. 3rd ed.,
1994 (Chapter 6 and Chapter 8). In some instances, further
purification was done by size exclusion chromatography using a
HiLoad 26/60 Superdex pg 75 column (GE Healthcare) operated with 50
mM Tris pH 8.0 and 200 mM NaCl. For storage, the MIC-1 compounds
was transferred to DPBS, and stored frozen.

Example-3: pH-Dependent Solubility of MIC-1 Compounds of the
Invention
[0143] The purpose of this experiment was to screen for the MIC-1
compounds with improved solubility, and determine the optimal pH
window for formulation.
[0144] MIC-1 compounds were dissolved in a mixture of water and
ethanol (60% water and 40% ethanol) with a concentration range
between 3 mg/ml to 10 mg/ml. The solvent was evaporated with
SpeedVac (Concentrator Plus, Eppendorf) for 6 hours to obtain
pellet of said MIC-1 compound.
[0145] Below buffers were used for this pH-dependent solubility
curve assay: acetate buffer (pH 3 to pH 6); Tris buffer (pH 7 to pH
9); CAPS buffer (pH 10 to pH 11).
[0146] Buffers were added into each well of the 96-well plate
together with MIC-1 compounds. The amount used may not be exactly
the same but all targeting a theoretical concentration within 12-18
mg/ml. The concentration of MIC-1 compounds in the supernatant was
determined by UPLC (Table 6). Based on the results, solubility of
the MIC-1 compounds of the invention was significantly improved
between pH 6-9 compared with wtMIC-1. The optimal pH window of the
MIC-1 compounds falls into the pH range that is preferred for
formulation, e.g. pH 6.5-8.5.

Example 4: Maximal Solubility of MIC-1 Compounds at pH 8
[0147] In order to test the maximal solubility, the MIC-1 compounds
were dissolved in a mixture of water and ethanol (60% water and 40%
ethanol) with a concentration range between 3 mg/ml to 10 mg/ml.
Then the solution (150 .mu.L each well) was aliquot into a 96-well
plate (Corning). The solvent was evaporated with SpeedVac
(Concentrator Plus, Eppendorf) for 6 hours to obtain pellet of the
MIC-1 compound. Tris buffer (pH 8.0, without excipients) was added
into each well of the 96-well plate. The amount of buffer added to
the well was less than the amount needed for solving the whole
pellet in the well, so that maximal concentration was achieved. The
plate was shaken on a plate shaker at 800 rpm (MixMate, Eppendorf)
for 2 hours. The pellet was spun down at 3600 g for 5 min. The
supernatants were transferred to a 96-deep-well plate and diluted
20 times with 40% ethanol. Then all of the samples were subject to
UPLC (Acquity, Waters), plate reader (Infinite M200 pro, Tecan) and
UV spectrometer (NanoDrop 8000, Thermo Scientific) to determine the
concentration (Table 7)
[0148] Based on the results, solubility of the MIC-1 compounds of
the invention was significantly improved at pH 8.0. Especially, the
MIC-1 compounds with N-extensions achieved solubility of more than
30 mg/ml at pH 8.0.

General Methods of In Vitro Activity Screening
Example 5: Establishment of BHK21-hGFRAL-IRES-hRET Cell Line
[0149] The purpose of this example was to establish a cell based in
vitro assay for testing MIC-1 activity. Mammalian cells were
transfected and stably expressed full length MIC-1 receptor
(hGFRAL) and its full signaling co-receptor hRET51.
[0150] Plasmids expressing full length hGFRAL and full length
hRET51 were constructed by inserting synthesized DNA nucleotides
encoding full length hGFRAL and full length hRET51 into mammalian
expression vector pEL. IRES (internal ribosome entry site) is a
commonly used linker between two DNA sequences, so that the two DNA
sequences can be simultaneously translated into mRNA. pEL vector
backbone was provided by Taihegene CRO company.
[0151] Two millions of BHK21 cells were seeded in a 10 cm petri
dish and cultured for overnight in culture medium (DMEM+10% FBS+1%
PS). Cells were transfected with pEL-hGFRAL-IRES-hRET plasmids.
Transfected cells were split into new 10 cm dishes at different
densities and grew in selection medium (DMEM+10% FBS+1% PS+1 mg/ml
G418) for more than 2 weeks to get single clones. The single clones
were transferred to 6 well plates and cultured to 100% confluence.
mRNA expression of hGFRAL and hRET was measured by qPCR.
Successfully transfected clones were picked up and tested for MIC-1
binding (FIG. 15 and Table 13).
Example 6: MIC-1 Cell-Based In Vitro Activity Assay
[0152] wtMIC-1 and MIC-1 compounds induced both phosphorylation of
ERK1/2 in BHK21-hGFRAL-IRES-hRET stable cells (Table 8). It can be
concluded from the results that the ternary complex of MIC-1, GFRAL
and RET phosphorylates RET protein tyrosine kinase to induce in
vivo activities of MIC-1 through signal pathways comprising
ERK/MAPK pathway by phosphorylation of ERK1/2.
[0153] Results from screening MIC-1 compounds using
BHK21-hGFRAL-IRES-hRET is shown in Table 8. MIC-1 compounds with
N-extensions only or MIC-1 analogues with in-sequence mutations
only achieved in vitro activity equal to or even higher than
wtMIC-1. Also, combination of N-extension and in-sequence mutations
can also achieve similar activity.

[0154] Increasing solubility of MIC-1 may also be achieved by
N-terminal fusion of MIC-1 polypeptides with Human Serum Albumin
(HSA). It is known that HSA fusion could increase the solubility of
MIC-1. Two such HSA-MIC-1 fusion proteins were tested for in vitro
activity (Table 9).

[0155] A significant loss of potency was observed, thus
demonstrating that these MIC-1 fusion proteins with high solubility
did not retain receptor potency.
In Vivo Efficacy
Example 7: Effect of MIC-1 Compounds on Food Intake in Lean Sprague
Dawley Rats
[0156] The in vivo efficacy of MIC-1 compounds of the invention was
measured in 9-11 weeks old lean male Sprague Dawley rats. Animals
were injected once daily with a dose of 8 nmol/kg body weight (4
nmol/kg for two HSA-MIC-1 fusion proteins) 1-2 hrs before the onset
of the dark period. Compounds were administrate subcutaneously (1-4
ml/kg) in appropriate buffered solution. Changes in food intake
were measured by automatic food monitoring systems (BioDAQ system
and HM2 system for rat). In the BioDAQ system animals were single
housed; and in the HM2 system animals were in group housed with up
to 3 animals per cage. Each compound was tested in n=4-8 animals.
Animals were acclimatized for at least 7 days prior to the
experiment. Collected data are expressed as daily food intake (24
hour food intake) measured from the onset of each daily 12 hour
dark phase to the next day dark phase. Daily changes in food intake
in response to administrated compound were calculated by
subtracting the average daily food intake of the vehicle group from
the average daily food intake of the treatment group. Changes were
considered significant if p<0.1 using a two-tailed student's
t-test ( ). Results are expressed as the "maximum reduction" in
food intake compared with vehicle (percentage) recorded during the
study period. Data are also expressed as the "accumulated
reduction" in food intake which as the sum of significant
(p<0.1) daily reductions in food intake (percentage) during the
study period.

[0157] The inventors surprisingly found that these MIC-1 compounds
not only increased the solubility molecules but also resulted in
efficacy equal to or even better than wtMIC-1 (Table 10). For
instance compounds according to SEQ ID NO:105 and SEQ ID NO:106 had
a maximum and accumulated in vivo efficacy which was 40-50% greater
than wtMIC-1 with subcutaneous dosing. The increase in efficacy was
furthermore associated with an increase in solubility as compounds
according to SEQ ID NO:92, SEQ ID NO:104, SEQ ID NO:105 and SEQ ID
NO:106 all had elevated solubility and a significant greater in
vivo efficacy compared with wtMIC-1. This correlation seems not to
be explained by changes in the in vitro Emax as all compounds in
table 10, except compound according to SEQ ID NO:105, had an Emax
comparable with wtMIC-1. In fact, compound SEQ ID NO:105 had a
lower Emax than wtMIC-1 and was still more efficacious than wtMIC-1
in vivo. Also, the in vitro potencies were comparable between
compounds as none of the compounds had an EC50 which differed from
wtMIC-1. Thus, the association between increased in vivo efficacies
and increased solubility is surprising and cannot be simply be
explained by changes in increased receptor activation in vitro.
Example 8: MIC-1 Expression and Initial Met Removal Efficiency of
Different 12-mer Blocks
[0158] In the human body, N-Formyl-Methionine is recognized by the
immune system as foreign material, or as an alarm signal released
by damaged cells, and stimulates the body to fight against
potential infection (Pathologic Basis of Veterinary Disease5:
Pathologic Basis of Veterinary Disease, By James F. Zachary, M.
Donald McGavin). In addition, Methionine is an instable residue
that could be easily oxidized. Therefore, the N-Met cleavage
efficiency is very important to MIC-1 expression.
[0159] There are 4 different types of 12mers, and all of them are
comprised of 3 Ser, 2 Pro, 2 Gly, 2 Thr, 2 Glu and 1 Ala. However,
the 12 residues in each repeat are arranged in different ways.
[0160] Little is known about the effects of different 12mers on the
expression level and the N-Met cleavage efficiency. Thus,
systematically investigation of MIC-1 compounds initiating with
single and double 12mers respectively is quite necessary.
[0161] The cDNA of MIC-1 compound was sub-cloned into a pET11b
derived vector. Overexpression of MIC-1 compounds as inclusion
bodies or soluble protein was induced in E. coli by 0.5 mM
isopropyl .beta.-d-thiogalactoside (IPTG) when the cell density
reached an OD600 of 1.0. After continuous growth in TB for 20 h at
37.degree. C., the cells were harvested and sonicated in buffer A
(20 mM Tris, pH 8.0). The resulting mixture was centrifugated at
10,000 g for 20 min and analysed by LC/MS and SDS-PAGE to confirm
the molecular weight.
[0162] Fermentation was carried out on fed-batch process in
chemical defined medium as supplement. Fermentation yield largely
depended on different compounds, which varied from 1 g/L to 8 g/L
from compound to compound.
[0163] Compounds designed for the single-12mer test and the result
are shown in Table 11 and FIG. 1.

SEPATSGSETP G (SEQ ID NO: 181) N/A: means MIC-1 compound with the
N-extension did not express in E.coli.
[0164] In conclusion, N-extensions starting with the 12mer-1 block
could not be expressed in E. coli. For the other 12mer blocks,
protein expression was achieved but only 12mer-4 as the initial
sequence resulted in complete methionine cleavage. In addition, the
N-met cleavage efficiency of 12mer-2 series is better than that of
12mer-3 series.

"latter" means the last 6aa of 12mers, "inter" means the internal
6aa from 12mers.
[0167] Although the extended 12mer (baa) locate 24aa away from the
N-terminal, the expression levels of MIC-1 compound vary a lot
among different groups. It is clear that the fragment from 12mer-1
is not suitable for expression, which is consistent with previous
results. The average expression levels of 12mer-(4+_+3.6) and
-(4+_+4.6) are relatively higher than others.
(2) Inclusion Body Ratio of MIC-1 Compound with 2* or 2.5*12mer
N-Extension
[0168] For large scale protein production, inclusion body is
usually considered as a good choice mainly due to its better
up-scaling properties, which mainly include: high expression level,
simple recovery step and high purity, protease-resistant and good
process stability.
[0169] MIC-1 compounds could be expressed either inclusion body or
soluble form, which is mainly dependent on compounds' pI and
extension length. The results are shown in Table 14 and FIG. 4.

body. It was shown that the inclusion body ratio is >90% when
pI>5.1. In addition, MIC-1 compounds with in-sequence mutations
M57E/H66E mainly expressed soluble fractions.
