Company focuses efforts and resources on advancing SRF617 and SRF388; Implements strategic restructuring
Initial clinical updates for SRF617 and SRF388 expected by the end of 2020Extends current cash runway into 2022CAMBRIDGE, Mass., Jan. 27, 2020 (GLOBE NEWSWIRE) — Surface Oncology (NASDAQ:SURF), a clinical-stage immuno-oncology company developing next-generation immunotherapies that target the tumor microenvironment, today announced the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) applications for its antibody candidates, SRF617 (targeting CD39) and SRF388 (targeting IL-27), and the Company is executing on plans to initiate clinical trials to advance both programs.“Since Surface’s founding approximately five years ago, we have brought four novel, internally developed programs to the IND stage,” said Jeff Goater, chief executive officer. “The entire team is very proud of this impressive accomplishment. As we strive to have a positive impact on the treatment of people who are diagnosed with cancer, we have decided it is in the best interest of our overall mission to focus our resources on the SRF617 and SRF388 programs. Restructuring was a difficult decision because of the effect it has on our dedicated and talented people. I am extremely grateful for the efforts of our employees and their tremendous contributions to Surface’s rapid progress and strong culture. We are committed to supporting all of our employees during this transition.”The active INDs for both SRF617 and SRF388 enable Surface Oncology to initiate phase 1 clinical trials for each product candidate. The Company anticipates providing initial clinical updates for both SRF617 and SRF388 by the end of 2020.SRF617 is a fully human anti-CD39 antibody designed to promote anti-tumor immunity through a dual mechanism of reducing immunosuppressive adenosine and driving the extracellular accumulation of immunostimulatory ATP within the tumor microenvironment. Due to this dual mechanism, Surface Oncology believes CD39 is the most promising therapeutic target on the adenosine axis, a notable immunosuppressive pathway. The Company’s phase 1/1b trial will evaluate SRF617 in patients with advanced solid tumors both as a monotherapy and in combination with other cancer therapies.
 SRF388 is a fully human anti-IL-27 antibody designed to inhibit the activity of this highly immunosuppressive cytokine. Surface Oncology has identified particular tumor types, including hepatocellular and renal cell carcinoma, where IL-27 appears to play an important role in the immunosuppressive tumor microenvironment and may contribute to resistance to treatment with checkpoint inhibitors. Furthermore, the Company has identified a potential biomarker associated with IL-27 that may be useful in helping identify patients most likely to respond to SRF388.The Company also remains encouraged by the promise and progress of its wholly-owned, earlier-stage programs, SRF813 (targeting CD112R) and a regulatory T cell program, and will seek to partner these programs.The strategic restructuring will reduce the Company’s workforce by approximately 35%. With these steps to focus resources, Surface Oncology’s current cash and cash equivalents are now projected to fund the Company into 2022. Anticipated milestones under the NZV930 (targeting CD73) collaboration with Novartis and additional capital potentially available under the K2 HealthVentures debt financing, in aggregate, would extend Surface Oncology’s cash runway into the second half of 2022.About Surface Oncology:
