TRACON Pharmaceuticals Announces IND Filing of DE-122 (TRC105) for the Treatment of Wet Age-Related Macular Degeneration by Santen Pharmaceutical

SAN DIEGO and OSAKA, Japan, July 1, 2015 (GLOBE NEWSWIRE) -- TRACON Pharmaceuticals (NASDAQ:TCON) today announced that its partner, Santen Pharmaceutical Co. Ltd. (Santen), filed an Investigational New Drug (IND) Application with the U.S. Food and Drug Administration (FDA) for the initiation of clinical studies for DE-122 in patients with wet AMD. DE-122 is the ophthalmic formulation of TRACON's proprietary anti-endoglin antibody, TRC105. In March 2014, Santen licensed the global rights for the development of TRC105 in ophthalmology from Tracon. Under the terms of the agreement, the IND filing for DE-122 triggers a $3 million milestone payment to TRACON.

"The IND filing for wet AMD is an important milestone for TRACON as it both diversifies our clinical pipeline beyond oncology, and provides meaningful non-dilutive capital," commented Charles Theuer, M.D., Ph.D., President and CEO of TRACON. "Our experience combining TRC105 with inhibitors of the VEGF pathway in cancer patients suggests that the development of DE-122 in wet AMD, where VEGF inhibitors are the established standard of care, has the potential to offer patients who receive little or no benefit from current therapy an important new treatment option. We look forward to continuing to work closely with Santen as the company initiates clinical studies of DE-122 in wet AMD."

"Santen is a global pharmaceutical company specialized in the field of ophthalmology, and it is committed to delivering novel medicines for the treatment of high unmet need ophthalmic conditions on a global basis. Treatment options for retinal disease, including wet AMD are limited, and thus, Santen is pleased to gain access to novel compounds such as DE-122, so that Santen can contribute to improving the quality of life of patients suffering from retinal disease such as wet AMD," said Akira Kurokawa, President and CEO of Santen.

About TRC105

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. TRC105 is also being developed in combination with VEGF inhibitor treatments in AMD. For more information about the clinical trials, please visit TRACON's website at

About Wet AMD

Wet AMD is the leading cause of blindness in the elderly in the world and is caused by excessive growth and leakage of blood vessels at the back of the eye that leads to a chronic and often rapid loss of vision. Existing therapies for the disease are limited, including treatment targeting the VEGF pathway.
