$康宁杰瑞制药-B(09966)$ 继续实验 TRACON Pharmaceuticals (NASDAQ: TCON), a clinical stage biopharmaceutical company utilizing a cost-efficient, CRO-independent Product Development Platform (PDP) to advance its pipeline of novel targeted cancer therapeutics and to partner with other life science companies, today announced the independent data monitoring committee (IDMC), following a review of ongoing safety and efficacy data on April 2, recommended the ENVASARC Phase 2 pivotal trial continue as planned. The ENVASARC Phase 2 pivotal trial completed enrollment in March 2024 with a total of 82 evaluable patients in cohort C of treatment with single agent envafolimab at 600 mg SQ every three weeks and final data are expected in the third quarter of 2024.
The IDMC reviewed interim safety and efficacy data from 73 patients enrolled into cohort C who had the opportunity to complete two on-treatment scans (a minimum of 12 weeks of treatment). The objective response rate (ORR) is currently 11% by investigator review and the confirmed ORR by blinded independent central review (BICR) is currently 5.5% (four patients). Median duration of response by BICR is greater than six months. Envafolimab has been well tolerated without the development of a single drug-related serious adverse event of grade 3 or higher. The primary endpoint of the study is achievement of an objective response in nine of 82 patients (11%) treated with envafolimab by BICR and median duration of response of greater than six months is a key secondary endpoint.
“Subcutaneous envafolimab has been generally well tolerated and continues to demonstrate durable single agent activity in a subset of these sarcoma patients,” said James Freddo, M.D., TRACON’s Chief Medical Officer. “An additional five objective responses confirmed by central review are needed to achieve our goal in the 82 patient cohort of single agent envafolimab treatment.”
“We believe that achievement of the primary endpoint in the ENVASARC trial would position envafolimab to become a potentially compelling treatment option for patients with the refractory sarcoma subtypes of UPS and MFS,” said Charles Theuer, M.D., Ph.D., TRACON’s Chief Executive Officer
