SAN DIEGO, CA, USA I April 12, 2019 I TRACON Pharmaceuticals (NASDAQ:TCON), a clinical stage biopharmaceutical company focused on the development and commercialization of novel targeted therapeutics for cancer and, through our license to Santen Pharmaceutical Co. Ltd., wet age-related macular degeneration, today announced that its Phase 3 TAPPAS trial evaluating TRC105 in combination with Votrient (pazopanib) in patients with advanced or metastatic angiosarcoma was terminated for futility based on the recommendation of the Independent Data Monitoring Committee (IDMC) following its review of interim unblinded safety and efficacy data from more than 120 patients enrolled in the trial at the time of the analysis.
TRACON will work with investigators to appropriately conclude the study in a manner consistent with the best interests of each patient. Data from this study will be analyzed and submitted for presentation at an upcoming scientific congress.
“We are disappointed that TRC105 in combination with Votrient did not demonstrate clinically meaningful efficacy in patients with advanced or metastatic angiosarcoma,” said Charles Theuer, M.D. Ph.D., President and CEO of TRACON. “Given these data, we will terminate further enrollment in company sponsored trials of TRC105 in oncology. We will continue to support our partner, Santen, in their development of DE-122 in wet AMD, where the anti-angiogenic and anti-fibrotic properties of endoglin inhibition may be more relevant than in oncology. We will also continue to develop our other drug candidates, including TRC253 in partnership with Janssen and TJ004309 (also known as TJ-D5) in partnership with I-Mab, and, intend to advance candidates within I-Mab’s broad bispecific pipeline into the clinic in the US as early as the beginning of next year. We will also continue our business development efforts to source additional innovative products to fortify our pipeline through risk share and cost share arrangements. On a financial note, as a result of the expected savings to be generated from terminating TRACON sponsored trials of TRC105, we anticipate our current cash runway will now extend into the third quarter of 2020.”

About the TAPPAS trial in Advanced or Metastatic Angiosarcoma
The TAPPAS trial was designed to compare treatment with TRC105 and Votrient to treatment with single agent Votrient in up to 340 patients with advanced or metastatic angiosarcoma. Patients were randomized in equal numbers and the primary endpoint was progression free survival by RECIST 1.1. Key secondary endpoints included objective response rate, overall survival, safety and tolerability.
About TRC105 (carotuximab)
TRC105, the oncology formulation of carotuximab, 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 has received orphan designation for the treatment of soft tissue sarcoma in both the US and EU. The ophthalmic formulation of TRC105, DE-122, is currently being studied in the randomized Phase 2 AVANTE trial in patients with wet AMD. For more information about the clinical trials, please visit TRACON’s website at www.traconpharma.com/clinical_trials.php.
About DE-122 (carotuximab)
DE-122, a novel ophthalmic formulation of carotuximab, is active in preclinical choroidal neovascularization (CNV) models and expected to enhance the effect of approved VEGF inhibitors used to treat wet AMD. DE-122 is being investigated in the Phase 2 randomized AVANTE trial assessing the efficacy and safety of intravitreal injections in combination with Lucentis® (ranibizumab) compared to Lucentis monotherapy in patients with wet AMD.
TRACON develops targeted therapies for cancer and, through our corporate partner Santen, ophthalmic diseases. The Company’s clinical-stage pipeline includes: DE-122, the ophthalmic formulation of carotuximab being developed in wet AMD through a collaboration with Santen Pharmaceutical Company Ltd.; TRC102, a small molecule being developed for the treatment of lung cancer and glioblastoma; and TRC253, a small molecule being developed for the treatment of prostate cancer. TRACON is actively seeking additional corporate partnerships whereby it leads regulatory and clinical development, and shares in the cost and risk of clinical development and commercialization of new product candidates. In these partnerships TRACON believes it can serve as a solution for companies without clinical and commercial capabilities in the United States.
