TRACON expects to report top-line progression-free survival (PFS) data from the study later this year, with the exact timing driven by the number of progression events or deaths (from any cause) that define PFS. The study is expected to yield between 80 and 110 events as confirmed by the study’s independent central review committee at the time of data readout, which is expected to provide between 70% and 80% power to detect an improvement in PFS from 4.8 months with Inlyta to 7.2 months with the combination of TRC105 and Inlyta. PFS will also be assessed in patients with predefined levels of two soluble biomarkers that correlated with response in the Phase 1b portion of the trial, osteopontin and TGF-β receptor III.
"The completion of enrollment in the TRAXAR study represents an important step in the development of TRC105 and keeps us on track to deliver top-line data later this year," said Charles Theuer, M.D., Ph.D., President and CEO of TRACON. "The TRAXAR study provides a strong example of the depth of the TRACON product development platform as we have efficiently conducted the study at more than 50 sites located in Europe and the United States."
About the TRAXAR Phase 2b Clinical Trial in RCC
The Phase 2b TRAXAR clinical trial is a multicenter, open-label, randomized clinical trial of TRC105 in combination with Inlyta versus Inlyta alone in patients with advanced or metastatic RCC. The primary endpoint of the Phase 2b study is progression-free survival and the trial enrolled 150 patients who failed one prior VEGF inhibitor in the study. Patients may have also failed one prior mTOR inhibitor and one prior immunotherapy. For additional information on this clinical trial, please visit www.clinicaltrials.gov, identifier NCT01806064.
About TRC105 (carotuximab)
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 one Phase 3 and multiple Phase 2 clinical trials sponsored by TRACON or the National Cancer Institute for the treatment of solid tumors 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 Phase 2 trial for patients with wet AMD.
