OXiGENE Reports Second Quarter 2008 Results

WALTHAM, Mass., Aug. 4, 2008 (PRIME NEWSWIRE) -- OXiGENE, Inc. (Nasdaq:OXGN) (Stockholm:OXGN), a clinical-stage, biopharmaceutical company developing novel therapeutics to treat cancer and eye diseases, reported financial results for the quarter ended June 30, 2008 and presented an update on recent clinical and corporate progress.

Financial Results

The Company reported a net loss for the second quarter of 2008 of $7.0 million, or $0.25 per share, compared with a net loss of $5.4 million, or $0.19 per share, for the same period in 2007.

For the six-month period ended June 30, 2008, the net loss was $12.5 million, or $0.44 per share, compared to a net loss of $9.3 million, or $0.33 per share, for the comparable period in 2007.

The increase in loss for both the three and six month periods was driven primarily by a higher level of clinical development activities, including the continued enrollment of both the ZYBRESTAT(tm) (fosbretabulin) pivotal registration trial in anaplastic thyroid cancer (ATC) and the Phase II trial of ZYBRESTAT in combination with standard chemotherapy and bevacizumab for the treatment of Non-Small Cell Lung Cancer, as well as the management of other ongoing clinical trials and drug development activities.

At June 30, 2008, OXiGENE had cash, cash equivalents and marketable securities of approximately $18.3 million compared with approximately $28.4 million on December 31, 2007.

"The second quarter of 2008 was a period of steady advancement for each of our programs, as well as our corporate and business development initiatives," commented Richard Chin, OXiGENE's President and CEO. "Vascular disrupting agents in general, and ZYBRESTAT in particular, are receiving increasing attention as the next generation of anti-vascular therapies for cancer and diseases involving neovascularization of the eye."

Clinical Highlights / Update

   * In May, at the 11th International Workshop on the Tumor    Microenvironment, Hypoxia, Angiogenesis and Vasculature, the Company    presented previously announced results from topical-route, ocular    penetration studies in primates and rabbits. This was the first    formal presentation of the previously-announced data from these    studies.   * At the 2008 American Society of Clinical Oncology (ASCO) annual    meeting, the company reported data from a phase I study of ZYBRESTAT    (fosbretabulin) and bevacizumab in subjects with advanced solid    tumors. The study found that the combination appears safe and    well-tolerated, and shows signs of clinical activity.   * At the 2008 ASCO meeting, the company reported data from an ongoing    Phase I study of vascular disrupting agent OXi4503 in patients with    advanced solid tumors.  The study found that the drug appears well    tolerated, and shows evidence of both clinical and functional    imaging activity.

About ZYBRESTAT (fosbretabulin)

ZYBRESTAT is currently being evaluated in a pivotal registration study in ATC under a Special Protocol Assessment agreement with the U.S. Food and Drug Administration (FDA). OXiGENE believes that ZYBRESTAT is poised to become the first therapeutic product in a novel class of small-molecule drug candidates called vascular disrupting agents (VDAs). Through interaction with vascular endothelial cell cytoskeletal proteins, ZYBRESTAT selectively targets and collapses tumor vasculature, thereby depriving the tumor of oxygen and causing death of tumor cells. In clinical studies in solid tumors, ZYBRESTAT has demonstrated potent and selective activity against tumor vasculature, as well as clinical activity against ATC, ovarian cancer, and various other solid tumors. In clinical studies in patients with forms of macular degeneration, intravenously-administered ZYBRESTAT has demonstrated clinical activity, and the Company is working to develop a convenient and patient-friendly topical formulation of ZYBRESTAT for ophthalmological indications.

About OXi4503

OXi4503 (combretastatin A1 di-phosphate / CA1P) is a dual-mechanism VDA that is being developed in clinical studies for the treatment of solid and liquid tumors. Like its structural analog, ZYBRESTAT(tm) (fosbretabulin / CA4P), OXi4503 has been observed to block and destroy tumor vasculature, resulting in extensive tumor cell death and necrosis. In addition, preclinical data indicates that OXi4503 is metabolized by oxidative enzymes (e.g., tyrosinase and peroxidases), which are elevated in many solid tumors and tumor white blood cell infiltrates, to an orthoquinone chemical species that has direct cytotoxic effects on tumor cells. Preclinical studies have shown that OXi4503 has (i) single-agent activity against a range of xenograft tumor models; and (ii) synergistic or additive effects when incorporated in various combination regimens with chemotherapy, molecularly-targeted therapies (including tumor-angiogenesis inhibitors), and radiation therapy. OXi4503 is currently being evaluated as a monotherapy in a Phase I dose-escalation clinical trial in patients with advanced solid tumors.


OXiGENE is a clinical-stage biopharmaceutical company developing novel therapeutics to treat cancer and eye diseases. The company's major focus is developing VDAs that selectively disrupt abnormal blood vessels associated with solid tumor progression and visual impairment. OXiGENE is dedicated to leveraging its intellectual property and therapeutic development expertise to bring life-extending and -enhancing medicines to patients.
