About OXi4503

OXi4503 (combretastatin A1 diphosphate / CA1P) is a dual-mechanism vascular disrupting agent (VDA) that is being developed in clinical trials for the treatment of leukemias. Like its structural analog, ZYBRESTAT (fosbretabulin / CA4P), OXi4503 has been observed to block and destroy tumor vasculature, resulting in extensive tumor cell death and necrosis. In addition, preclinical data indicate 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 has been evaluated as a monotherapy in a Phase 1 dose-escalation trial in patients with advanced solid tumors and in patients with cancers involving the liver.


OXiGENE is a clinical-stage biopharmaceutical company developing novel therapeutics to treat cancer. The Company's major focus is developing vascular disrupting agents (VDAs) that selectively disrupt abnormal blood vessels associated with solid tumor progression. The Company's lead clinical product, ZYBRESTAT, is in development as a potential treatment for ovarian cancer and anaplastic thyroid cancer (ATC). OXiGENE is dedicated to leveraging its intellectual property and therapeutic development expertise to bring life-extending and life-enhancing medicines to patients.
