`SPECIFIC BINDING AGENTS OF HUMAN
`ANGOPOETIN-2
`
`This application claims benefit to U.S. Provisional Appli
`cation Ser. No. 60/414,155, filed Sep. 27, 2002, and U.S.
`Provisional Application Ser. No. 60/328,624 filed Oct. 11,
`2001, which are incorporated herein by reference in their
`entirety.
`
`FIELD OF INVENTION
`
`The present invention relates to specific binding agents
`that recognize and bind to angiopoietin-2 (Ang-2). More
`specifically, the invention relates to the production, diag
`nostic use, and therapeutic use of the specific binding agents
`and fragments thereof, which specifically bind Ang-2.
`
`BACKGROUND OF THE INVENTION

`(Davis, S., et al., 1996, supra; Maisonpierre, P. C., et al.,
`1997, supra; Kim, I., J. H. Kim, et al., Oncogene 19(39):
`4549–4552 (2000); Teichert-Kuliszewska, K., P. C. Maison
`pierre, et al., Cardiovascular Research 49(3): 659–70
`(2001)).
`The phenotypes of mouse Tie-2 and Ang-1 knockouts are
`similar and Suggest that Ang-1-stimulated Tie-2 phosphory
`lation mediates remodeling and Stabilization of developing
`vessels in utero through maintenance of endothelial cell
`Support cell adhesion (Dumont, D. J., et al., Genes &
`Development, 8:1897–1909 1994: Sato, T. N., et al.,
`Nature, 376:70–74 (1995: Suri, C., et al., 1996), supra).
`The role of Ang-1 in vessel stabilization is thought to be
`conserved in the adult, where it is expressed widely and
`constitutively (Hanahan, D., Science, 277:48–50 1997:
`Zagzag, D., et al., Experimental Neurology, 159:391-400
`1999). In contrast, Ang-2 expression is primarily limited to
`sites of vascular remodeling, where it is thought to block
`Ang-1 function, thereby inducing a state of vascular plas
`ticity conducive to angiogenesis (Hanahan, D., 1997.
`supra: Holash, J., et al., Science, 284: 1994–1998 1999:
`Maisonpierre, P. C., et al., 1997, supra).
`Numerous published studies have purportedly demon
`strated vessel-selective Ang-2 expression in disease states
`associated with angiogenesis. These pathological conditions
`include, for example, psoriasis, macular degeneration, and
`cancer (Bunone, G., et al., American Journal of Pathology,
`155:1967–1976 (1999: Etoh, T., et al., Cancer Research,
`61:2145–2153 2001; Hangai, M., et al., Investigative Oph
`thalmology & Visual Science, 42:1617–1625 2001;
`Holash, J., et al., 1999 Supra; Kuroda, K., et al., Journal of
`Investigative Dermatology, 116:713–720 2001: Otani, A.,
`et al., Investigative Ophthalmology & Visual Science,
`40:1912–1920 1999: Stratmann, A., et al., American Jour
`nal of Pathology, 153:1459–1466 1998: Tanaka, S., et al.,
`J Clin Invest, 103:34–345 (1999: Yoshida, Y., et al., Inter
`national Journal of Oncology, 15:1221–1225 1999: Yuan,
`K., et al., Journal of Periodontal Research, 35:165-171
`2000; Zagzag, D., et al., 1999 Supra). Most of these
`studies have focused on cancer, in which many tumor types
`appear to display vascular Ang-2 expression. In contrast
`with its expression in pathological angiogenesis, Ang-2
`expression in normal tissues is extremely limited (Maison
`pierre, P. C., et al., 1997, supra; Mezquita, J., et al.,
`Biochemical and Biophysical Research Communications,
`260:492-498 (1999). In the normal adult, the three main
`sites of angiogenesis are the ovary, placenta, and uterus;
`these are the primary tissues in normal (i.e., non-cancerous)
`tissues in which Ang-2 mRNA has been detected.
`Certain functional studies suggest that Ang-2 may be
`involved in tumor angiogenesis. Ahmad et al. (Cancer Res.,
`61: 1255–1259 (2001) describe Ang-2 over-expression and
`show that it is purportedly associated with an increase in
`tumor growth in a mouse Xenograft model. See also Etoh et
`al., Supra, and Tanaka et al., Supra, wherein data is presented
`purportedly associating Ang-2 over expression with tumor
`hypervascularity. However, in contrast, Yu et al. (Am. J.
`Path., 158:563–570 2001) report data to show that over
`expression of Ang-2 in Lewis lung carcinoma and TA3
`mammary carcinoma cells purportedly prolonged the Sur
`vival of mice injected with the corresponding transfectants.
`In the past few years, various publications have Suggested
`Ang-1. Ang-2 and/or Tie-2 as a possible target for anticancer
`therapy. For example, U.S. Pat. Nos. 6,166,185, 5,650,490,
`and 5,814,464 each disclose the concept of anti-Tie-2 ligand
`antibodies and receptor bodies. Lin et al. (Proc. Natl. Acad.
`Sci USA, 95:8829–8834 (1998) injected an adenovirus
`
`Angiogenesis, the formation of new blood vessels from
`existing ones, is essential to many physiological and patho
`logical processes. Normally, angiogenesis is tightly regu
`lated by pro- and anti-angiogenic factors, but in the case of
`diseases such as cancer, ocular neovascular diseases, arthri
`tis, and psoriasis, the process can go awry. Folkman, J., Nat.
`Med., 1:27–31 (1995).
`There are a number of diseases known to be associated
`with deregulated or undesired angiogenesis. Such diseases
`include, but are not limited to, ocular neovascularisation,
`Such as retinopathies (including diabetic retinopathy), age
`related macular degeneration, psoriasis, hemangioblastoma,
`hemangioma, arteriosclerosis, inflammatory disease. Such as
`a rheumatoid or rheumatic inflammatory disease, especially
`arthritis (including rheumatoid arthritis), or other chronic
`inflammatory disorders, such as chronic asthma, arterial or
`post-transplantational atherosclerosis, endometriosis, and
`neoplastic diseases, for example so-called solid tumors and
`liquid (or hematopoietic) tumors (such as leukemias and
`lymphomas). Other diseases associated with undesired
`angiogenesis will be apparent to those skilled in the art.
`Although many signal transduction systems have been
`implicated in the regulation of angiogenesis, one of the
`best-characterized and most endothelial cell-selective sys
`tems involves the Tie-2 receptor tyrosine kinase (referred to
`as “Tie-2 or “Tie-2R (also referred to as “ORK'); murine
`Tie-2 is also referred to as “tek’) and its ligands, the
`angiopoietins (Gale, N. W. and Yancopoulos, G. D., Genes
`Dev. 13:1055–1066 (1999). There are 4 known angiopoi
`etins; angiopoietin-1 ("Ang-1') through angiopoietin-4
`('Ang-4). These angiopoietins are also referred to as “Tie-2
`ligands'. (Davis, S., et al., Cell, 87:1161–1169 1996:
`Grosios, K., et al., Cytogenet Cell Genet, 84:118-120
`1999; Holash, J., et al., Investigative Ophthalmology &

`AcadSci USA,95:8829–8834 (1998: Maisonpierre, P. C., et
`al., Science, 277:55–60 1997; Papapetropoulos, A., et al.,

`Ang-1 binding to Tie-2 stimulates receptor phosphorylation
`in cultured endothelial cells, Ang-2 has been observed to

`expressing soluble Tie-2 into mice; the soluble Tie-2 pur
`portedly decreased the number and size of the tumors
`developed by the mice. In a related study, Lin etal (J. Clin.
`Invest., 100:2072–2078 (1997) injected a soluble form of
`Tie-2 into rats; this compound purportedly reduced tumor
`size in the rats. Siemeister et al. (Cancer Res., 59:3185-3189
`1999) generated human melanoma cell lines expressing the
`extracellular domain of Tie-2, injected these cell lines into
`nude mice, and concluded that soluble Tie-2 purportedly
`resulted in a “significant inhibition of tumor growth and
`tumor angiogenesis. In view of this information, and given
`that both Ang-1 and Ang-2 bind to Tie-2, it is not clear from
`these studies whether Ang-1. Ang-2, or Tie-2 would be an
`attractive target for anti-cancer therapy.
`The fusion of certain peptides to a stable plasma protein
`Such as an Ig constant region to improve the half-life of these
`molecules has been described in, for example, PCT publi
`cation WO 00/24782, published May 4, 2000.
`The fusion of a protein or fragment thereof to a stable
`plasma protein such as an Ig constant region to improve the
`half-life of these molecules has been variously described
`(see, for example, U.S. Pat. No. 5,480,981; Zheng et al., J.
`Immunol. 154:5590–5600, (1995); Fisher et al., N. Engl. J.
`Med., 334:1697–1702, (1996); Van Zee, K. et al., J. Immu

`(1989); Harvillet al., Immunotech. 1:95-105, (1995); WO
`97/23614, published Jul. 3, 1997; PCT/US 97/23183, filed

`WO95/21258, published Aug. 10, 1995).
`An effective anti-Ang-2 therapy might benefit a vast
`population of cancer patients because most solid tumors
`require neovascularization to grow beyond 1–2 millimeters
`in diameter. Such therapy might have wider application in
`other angiogenesis-associated diseases as well. Such as ret
`inopathies, arthritis, and psoriasis.
`There is an undeveloped need to identify new agents that
`specifically recognize and bind Ang-2. Such agents would
`be useful for diagnostic screening and therapeutic interven
`tion in disease states that are associated with Ang-2 activity.
`Accordingly, it is an object of the present invention to
`provide specific binding agents of Ang-2 that modulate
`Ang-2 activity. Such agents of the present invention take the
`form of peptibodies, i.e., peptides fused to other molecules
`Such as an Fc domain of an antibody, where the peptide
`moiety specifically binds to Ang-2.
