Trial to Continue as Planned

SAN DIEGO, Aug. 10, 2022 (GLOBE NEWSWIRE) -- TRACON Pharmaceuticals, Inc. (Nasdaq: TCON), a clinical stage biopharmaceutical company utilizing a cost-efficient, CRO-independent product development platform to advance its pipeline of novel targeted cancer therapeutics and to partner with other life science companies, today announced that the Independent Data Monitoring Committee for the ENVASARC pivotal trial has recommended that the trial proceed as planned following the review of three week safety data from more than 20 patients enrolled into the trial as of June 30, 2022. The safety data reviewed included data from more than 10 patients enrolled into cohort A of treatment with single agent envafolimab at 600 mg administered subcutaneously every three weeks and more than 10 patients enrolled into cohort B of treatment with envafolimab at 600 mg administered subcutaneously every three weeks with Yervoy (ipilimumab) given intravenously.

“Envafolimab at the 600 mg dose has been well tolerated as a single agent and when combined with Yervoy in refractory sarcoma patients who are enrolled in the ENVASARC trial. We remain on track for the Independent Data Monitoring Committee to review interim efficacy data in the fourth quarter of this year,” said James Freddo, M.D., TRACON’s Chief Medical Officer.

About Envafolimab

Envafolimab (KN035), a single-domain antibody against PD-L1 invented by Alphamab Oncology, is the first approved subcutaneously injected PD-(L)1 inhibitor. Envafolimab was approved by the Chinese NMPA in November 2021 in adult patients with MSI-H/dMMR advanced solid tumors who failed systemic treatment and have no satisfactory alternative treatment options. In December 2019, Alphamab Oncology, 3D Medicines and TRACON entered into a collaboration whereby TRACON has the right to develop and commercialize envafolimab in soft tissue sarcoma in North America. Envafolimab is currently being studied in the pivotal ENVASARC Phase 2 trial in the United States sponsored by TRACON and a Phase 3 pivotal trial in combination with gemcitabine and oxaliplatin in advanced biliary tract cancer patients in China sponsored by TRACON’s corporate partners, Alphamab Oncology and 3D Medicines.

About ENVASARC (NCT04480502)

The ENVASARC pivotal trial is a multicenter, open label, randomized, non-comparative, parallel cohort study at 30 top cancer centers in the United States and the United Kingdom that began dosing in December 2020. TRACON expects the trial to enroll more than 160 patients with UPS or MFS who have progressed following one or two lines of prior treatment and have not received an immune checkpoint inhibitor, with 80 patients enrolled into a cohort of treatment with single agent envafolimab at 600 mg every three weeks and 80 patients enrolled into a cohort of treatment with envafolimab at 600 mg every three weeks with Yervoy®. The primary endpoint is objective response rate by central review with duration of response a key secondary endpoint.
