TRACON Announces FDA Orphan Drug Designation for TRC105 in Soft Tissue Sarcoma

SAN DIEGO, Jan. 25, 2016 -- TRACON Pharmaceuticals (NASDAQ:TCON), a clinical stage biopharmaceutical company focused on the development and commercialization of novel targeted therapeutics for cancer, wet age-related macular degeneration and fibrotic diseases, announced today that the U.S Food and Drug Administration (FDA) has granted TRC105 orphan drug designation for the treatment of patients with soft tissue sarcoma.

“Orphan drug designation for TRC105 underscores the high level of unmet medical need in patients with soft tissue sarcomas and validates our commitment to developing TRC105 in a variety of orphan drug indications,” said Charles Theuer, M.D., Ph.D., President and CEO of TRACON. “We are highly encouraged by the clinical data reported to date from the Phase 1b/2 trial of TRC105 in sarcoma patients, especially in patients with angiosarcoma. We look forward to the availability of complete results from the Phase 2 portion of the sarcoma trial and initiating a pivotal Phase 3 trial in patients with angiosarcoma in 2016.”

The FDA’s Orphan Drug Designation program provides orphan status to drugs and biologics that are being developed to address rare diseases or disorders that affect fewer than 200,000 people in the U.S. With orphan designation, TRACON qualifies for various incentives with respect to TRC105 for the treatment of soft tissue sarcoma, including tax credits for qualified clinical trials and seven years of market exclusivity upon regulatory approval.

About TRC105 and TRC205

TRC105 is a novel, clinical stage antibody to endoglin, a protein overexpressed on proliferating endothelial cells that is essential for angiogenesis, the process of new blood vessel formation. TRC105 is currently being studied in multiple Phase 2 clinical trials sponsored by both TRACON and the National Cancer Institute for the treatment of multiple solid tumor types in combination with VEGF inhibitors. The ophthalmic formulation of TRC105, DE-122, is being developed in a Phase 1 trial in wet AMD. TRC205, a second generation antibody to endoglin, is undergoing preclinical testing in models of fibrosis.

About Soft Tissue Sarcoma

Sarcomas are rare tumors that originate from mesenchymal tissues (e.g., bone, cartilage, fat and muscle). In the U.S., the incidence of soft tissue sarcomas is approximately 13,000 new cases per year, leading to approximately 5,000 deaths annually. Sarcomas account for nearly 21% of all pediatric solid cancers and less than 1% of all adult solid cancers. According to the WHO classification of 2002, over 70 different types of sarcoma have been described. The rarity and heterogeneity of the disease render sarcoma difficult to study and to treat. Endoglin, the target of TRC105 treatment, is overexpressed on many sarcoma subtypes, including angiosarcoma.
