Ltd. Also participating in this round were new investors Innovis Investments and Nextech Ventures, Ltd as well as existing investors Bear Stearns Health Innoventures, Alta Partners, HBM BioVentures, Lombard Odier Darier Hentsch & Cie, H&Q Life Sciences Investments, and Orbimed Associates. The company also announced that Kenan Turnacioglu, Ph.D., Managing Director at Duquesne Capital Management and Hironori Hozoji, Investment Officer of JAFCO Life Science Investment, have joined Agensys’ board of directors. “We are gratified with the reception we had for this financing in the investment community. It’s a reflection of our large antibody product pipeline addressing unmet medical needs in cancer. We also offer significant internal antibody development capabilities, very strong corporate alliances, and a seasoned management team,” said Donald B. Rice, Ph.D., Chairman, President and CEO of Agensys. “We will use the proceeds to advance our lead program through phase 2 and bring 3 more products into clinical development by the end of 2008. “We are also quite pleased to add Kenan Turnacioglu and Hironori Hozoji to our board of directors. They are both experienced investors in later stage private companies with valuable experience in the biotechnology industry.” “Therapeutic antibody companies are generating considerable interest among investors and corporate partners,” added Hironori Hozoji. “Agensys is a compelling opportunity with proprietary cancer targets, leading antibody technology, and a strong pipeline.” Agensys has 12 antibody (MAb) programs in its product pipeline. AGS-PSCA, partnered with Merck & Co., Inc., is the lead program and is in clinical development for prostate cancer. AGS-PSCA is a high affinity, fully human IgG1k MAb directed to PSCA, generated using XenoMouse® technology. PSCA is expressed at significant levels on tumor cells from a majority of patients with all stages of prostate, pancreatic and bladder cancers. Efficacy studies utilizing human specimens of these tumors in xenograft mouse models have consistently demonstrated that AGS-PSCA significantly inhibits both tumor growth and metastases. This MAb was well tolerated at all phase 1 doses and pharmacokinetic studies demonstrate a long half life and no antibody sink, enabling a convenient dosing regimen. The Company is targeting to file an IND in 2007 for AGS-16M18, a fully human antibody to its proprietary target AGS-16. This target is expressed in more than 90% of patients with kidney cancer and is involved in cell proliferation, invasion, and angiogenesis. Both AGS-PSCA and AGS-16M18 are so called “naked antibodies” which demonstrate anti-tumor activity when they bind the respective target and modulate its function. In a strategic move to broaden its pipeline beyond naked MAbs, Agensys announced earlier this year a broad collaboration with Seattle Genetics, Inc. to develop four antibody-drug conjugate (ADC) products. The ADCs will combine Agensys proprietary targets and fully human MAbs with Seattle Genetics’ linker and toxin technology. ADCs impact tumors differently than naked MAbs, as the antibody is used as a vehicle to deliver the toxin inside tumor cells leading to their killing. The collaboration is structured to develop 2 products on a 50-50 basis with Seattle Genetics and 2 products solely by Agensys. Work has begun on the first product, an ADC to the Agensys target, AGS-5, which is being developed as one of the 50-50 products in the collaboration. AGS-5 is expressed in prostate, lung, breast, and ovarian cancers. About Duquesne Capital Management Duquesne Capital Management, L.L.C. (“Duquesne”) was founded by Stanley F.
