SAN DIEGO, Nov. 09, 2017 — 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, today presented updated data from the Company’s Phase 1b/2 study of TRC105 and Votrient® (pazopanib) in patients with angiosarcoma at the Connective Tissue Oncology Society (CTOS) annual meeting taking place in Maui, Hawaii.
In poster presentation 2804349 entitled, “Every Other Week Dosing of TRC105 (Endoglin Antibody) in Combination with Pazopanib in Patients with Advanced Soft Tissue Sarcoma,” updated data were presented from 18 angiosarcoma patients treated with the combination of TRC105 and Votrient, and an additional cohort of six soft tissue sarcoma patients treated with a hybrid dosing schedule of TRC105 and Votrient. Key results included:TRC105 target concentrations previously shown to saturate endoglin receptors were achieved continuously using a TRC105 hybrid dosing schedule of 10 mg/kg weekly for four weeks followed by 15 mg/kg every other week.Median progression-free survival (PFS) was 7.8 months in 13 VEGF inhibitor naïve angiosarcoma patients treated with the combination of TRC105 and Votrient using either 10 mg/kg weekly dosing or the hybrid dosing schedule of TRC105. This compares favorably to the median PFS of 3 months reported in a retrospective study of single agent Votrient in patients with angiosarcoma.In the 17 patients who received prior treatment of metastatic disease, treatment duration on TRC105 and Votrient exceeded the duration of the most recent prior therapy in 7 of 12 VEGF naïve angiosarcoma patients and 2 of 5 patients who received a prior VEGF inhibitor as part of their most recent prior therapy.Treatment with the combination of TRC105 and Votrient continued to be well-tolerated and allowed for dosing of the combination for more than two years in patients who experienced complete responses to treatment.
“The combination of TRC105 and Votrient continues to demonstrate the potential to deliver meaningful benefits to angiosarcoma patients. We continue to achieve important progress with the clinical development of this compelling product candidate, as our pivotal Phase 3 TAPPAS trial is now open at more than 20 sites in the U.S., and European sites are expected to open by year-end,” said Charles Theuer, M.D., Ph.D., President and CEO of TRACON. “We also continue to evaluate every other week dosing of TRC105 in other indications, including lung and liver cancers.”The poster is available on TRACON’s website at www.traconpharma.com.About Carotuximab (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 a pivotal Phase 3 trial in angiosarcoma and multiple Phase 2 clinical trials, in combination with VEGF inhibitors. TRC105 has received orphan designation for the treatment of soft tissue sarcoma in both the U.S. and EU. The ophthalmic formulation of TRC105, DE-122, is currently in a randomized Phase 2 trial for patients with wet AMD.
