TRACON Pharmaceuticals Announces Top-line Data from Phase 2 TRAXAR Clinical Trial in Renal Cell Carcinoma
SAN DIEGO, Dec. 21, 2018 (GLOBE NEWSWIRE) -- 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 announced that its Phase 2 TRAXAR trial evaluating TRC105 in combination with Inlyta (axitinib) in patients with advanced or metastatic renal cell carcinoma did not meet the primary endpoint of improving progression free survival (PFS) in the intent to treat population compared to Inlyta monotherapy.
Prespecified statistical analyses of PFS according to expression of two plasma biomarkers, TGFβ receptor III and osteopontin, also did not achieve statistical significance. The safety profile observed in TRAXAR was consistent with that observed in previously reported studies of TRC105 in combination with VEGF inhibitors.
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 Inlyta did not demonstrate clinically meaningful efficacy in patients with advanced or metastatic renal cell carcinoma. Importantly, data from TRAXAR, including analyses of an extensive biomarker panel, will contribute to our understanding of the role of endoglin inhibition in combination with VEGF inhibitors, and may inform our broad TRC105 clinical development program,” said Charles Theuer, M.D., Ph.D., President and CEO of TRACON. “We remain focused on the interim analysis to determine the final sample size of the Phase 3 TAPPAS trial of TRC105 and Votrient in angiosarcoma, which is expected in the first quarter of 2019.”
About the TRAXAR trial in Advanced or Metastatic Renal Cell Carcinoma
The TRAXAR trial compared treatment with TRC105 and Inlyta to treatment with single agent Inlyta in 150 patients with advanced or metastatic renal cell carcinoma with a clear cell component. 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, safety and tolerability.
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, as well as in a Phase 1 trial with Opdivo. 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.

TRACON develops targeted therapies for cancer and ophthalmic diseases. The Company’s clinical-stage pipeline includes: TRC105, an endoglin antibody that is being developed for the treatment of multiple cancers; DE-122, the ophthalmic formulation of TRC105 that is 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.
