Surface Oncology Resets Portfolio Priorities, Extends Cash Runway Through 2021
Significantly reduces scope of its CD47 program, SRF231
Accelerates IND filing for SRF388 (IL-27) into Q4 2019
IND filing for SRF617 (CD39) remains on track for Q4 2019
“A disciplined approach to both drug development and portfolio prioritization is central to our mission to develop truly innovative immunotherapies to help those affected by cancer,” said
The company is conducting a multi-center, open-label phase 1 trial of SRF231 designed to assess safety and tolerability in multiple ascending doses. To date, 18 patients have been treated with SRF231 on an every-three-week schedule. During the dose escalation portion of the phase 1, two hematologic dose-limiting toxicities (DLTs) were seen at a lower dose (12 mg/kg) than anticipated and resolved without long-term toxicity. Surface will explore additional dose administration schedules but will not open expansion cohorts in the phase 1 study.
“While the early biological activity observed in the clinic with SRF231 potentially represents novel biology, specifically a lack of hemagglutination and differential effects on white blood cells, it does not meet our standard for pursuing additional clinical expansions at this time,” said
This outlined activity may support business development opportunities for SRF231. The company anticipates presenting additional SRF231 data in the second half of 2019.
Surface believes the reprioritization of its programs will extend the company’s projected cash runway through 2021 based upon its current operating plan, which includes advancing its next two preclinical programs SRF617 and SRF388 into clinical studies and through initial clinical data.
