TRACON Pharmaceuticals Announces Positive Results Based on Double-Digit Objective Response Rate in Each Cohort from the Ongoing ENVASARC Phase 2 Pivotal Trial
Objective Response Rate (ORR) by Central Review Achieved in Each Cohort at Interim Efficacy Analysis that Exceeded the Futility Threshold
Enrollment Continues Ahead of Schedule; Next Interim Analysis Expected in mid-2023 with Full Accrual Now Expected Before the End of 2023
Arbitration Decision Expected in 1Q 2023 has Potential to Increase Cash Runway
The IDMC reviewed interim safety and efficacy data from 18 patients enrolled into each cohort who completed a minimum of 12 weeks of efficacy evaluations (two on-treatment scans). The double-digit ORR assessed by blinded independent central review in each cohort more than satisfied the prespecified futility rule. Envafolimab monotherapy and in combination with Yervoy was well tolerated, with only a single related serious adverse event reported in 36 patients. Responses were noted in patients regardless of weight at the 600 mg dose of envafolimab that was instituted following the previous IDMC review of interim safety and efficacy data from patients in the ENVASARC trial treated at the 300 mg dose of envafolimab.
“We are pleased with the activity of the 600 mg dose of envafolimab that has demonstrated a double-digit objective response rate both as a single agent and in combination with Yervoy, even at this early 12-week time point,” said
“Achieving a double-digit ORR with a well tolerated safety profile, as both monotherapy and in combination, positions envafolimab to become a potential treatment option for patients with refractory
