Exhibit 99.1 OXiGENE Reports First Quarter 2004 Financial Results WALTHAM, Mass.--(BUSINESS WIRE)--April 28, 2004--OXiGENE, Inc. (NASDAQ: OXGN, XSSE: OXGN) Recent Accomplishments -- Announced positive pre-clinical data on OXi4503 at AACR -- Raised net proceeds of $22.3 million -- Strengthened management team -- Received European Union Orphan Drug Designation for CA4P OXiGENE, Inc. (NASDAQ: OXGN, XSSE: OXGN), a leading developer of biopharmaceutical compounds designed to target aberrant blood vessels within solid tumor cancers and ocular neovascular diseases, today reported financial results for the first quarter ended March 31, 2004. Licensing revenue for the first quarter of 2004 was $7,000 compared with $20,000 in the same period of 2003. The net loss for the three months ended March 31, 2004 was $2.1 million, or $0.13 per share, compared with a net loss of $1.5 million, or $0.12 per share, in the first quarter of 2003. Total operating expenses increased 44 percent in the first quarter of 2004 to $2.2 million from $1.5 million in the first quarter of 2003. This increase reflects higher research and development expenses and general and administrative costs. The R&D expenses are related to the ongoing clinical trials of the Company's lead compound, Combretastatin A4 Prodrug (CA4P), and to the advancement of OXi4503 into numerous pre-clinical tests. Since the end of the first quarter of 2003, CA4P has advanced into three human clinical trials in cancer and one in ophthalmology. The G&A costs are associated with the strengthening and retention of Company management and increased professional service fees in connection with being a public company. At March 31, 2004, OXiGENE had cash and available-for-sale securities of $39.0 million, up from $18.9 million at December 31, 2003. Patient enrollment is well underway in the six post-Phase I human studies of CA4P. These studies -- five in cancer and one in ophthalmology -- will enroll a total of approximately 200 patients in addition to the 100 patients treated in the Company's initial Phase I studies. At next month's 2nd International Vascular Targeting Conference in Florida, clinical investigators involved in several of the current clinical trials of CA4P are scheduled to present in the conference's Clinical Developments section. These investigators are involved in: 1) the Phase I/II study of CA4P in combination with the chemotherapy drugs Carboplatin/Paclitaxel in patients with advanced cancer and advanced ovarian carcinoma; 2) the Phase I/II combination trial of CA4P and radiotherapy in patients with advanced cancer of the lung, head & neck and prostate; and 3) the Phase I/II ophthalmology study of CA4P in patients with wet age-related macular degeneration. During the first quarter of 2004, pre-clinical data on OXiGENE's lead pre-clinical compound, OXi4503, was presented at the American Association for Cancer Research's 95th Annual Meeting. One study assessed the synergistic effects of OXi4503 with standard-of-care chemotherapy drugs Carboplatin and Paclitaxel in human breast and ovarian carcinoma models grown in mice. Another study measured OXi4503's pre-clinical efficacy and histopathologic effects in rodent KHT and human KSY sarcoma models and in a Caki-1 model of human renal cell carcinoma. Cancer Research UK, the world's largest volunteer-sponsored cancer research organization, is conducting pre-clinical toxicology testing on OXi4503. "Cancer Research UK is making steady progress in readying OXi4503 for study in humans," said Fred Driscoll, OXiGENE's president and chief executive officer. "Dose-escalating toxicology studies of the compound are being conducted in animals, and the data collected from these studies will be used to design the protocol for our initial study of the compound in humans. Pre-clinical testing continues on schedule, and we expect that OXi4503 will enter the clinic by the end of this year." Other recent highlights include: -- OXiGENE generated net proceeds of $22.3 million through a sale of 2,755,695 shares of Common Stock to certain institutional investors at $8.78 per share. -- James B. Murphy was hired as OXiGENE's chief financial officer and Scott L. Young, previously the Company's vice president of clinical and regulatory affairs, was promoted to the newly created post of chief operating officer. -- Retinal surgeon Eugene de Juan, Jr., M.D. was named to the Company's Clinical Trial Advisory Board. A professor of ophthalmology at the University of Southern California's Keck School of Medicine, de Juan will advise OXiGENE on the design of future ophthalmology trials and clinical study site selection. -- The Orphan Drug Medicinal Product Designation was awarded to CA4P as a treatment for anaplastic thyroid cancer. The designation would provide OXiGENE with market exclusivity in the European Union for 10 years following CA4P's market authorization.
