Schrödinger Reports Encouraging Initial Phase 1 Clinical Data for SGR-1505 at EHA Annual Congress

Schrödinger, Inc. (Nasdaq: SDGR) today announced encouraging initial clinical data from its ongoing Phase 1, open-label, dose-escalation study of SGR-1505 in patients with relapsed/refractory B-cell malignancies. SGR-1505 was observed to be safe, well tolerated, and clinically active, with responses observed in multiple histologies, including in patients with chronic lymphocytic leukemia (CLL) and Waldenström macroglobulinemia (WM). These data are being presented in a poster presentation at the European Hematology Association Annual Congress.

“We are very encouraged by the initial results from our Phase 1 study in patients with relapsed/refractory B-cell malignancies. The data presented today, coupled with the differentiated preclinical and safety profiles observed in our previously completed study in healthy volunteers, further increases our conviction about the potential for SGR-1505 to be a best-in-class therapy,” said Margaret Dugan, M.D., chief medical officer at Schrödinger. “Dose escalation is complete, and we look forward to discussing these results and our proposed recommended Phase 2 dose with the FDA later this year.”

“Despite recent advances in the treatment of B-cell malignancies, resistance to currently available therapies eventually results in treatment failure and disease progression for many patients,” said Stephen Spurgeon, M.D., Associate Professor of Medicine, Oregon Health and Science University, and an investigator for the clinical study. “We know that MALT1 plays a critical role in key signaling pathways that drive cancer cell survival and proliferation, making it a promising target for a broad range of B-cell malignancies. Although these data are from an early-phase study, they suggest SGR-1505 demonstrates on-target activity resulting in potential clinical benefit. I look forward to seeing additional data as the study progresses, including response data in patients with aggressive histologies.”

“The positive data reported today represent a key milestone for Schrödinger and follow the clinical successes of programs advanced by collaboration partners and companies we have co-founded,” said Karen Akinsanya, Ph.D., president, head of therapeutics R&D and chief strategy officer, partnerships at Schrödinger. “These data reinforce the power of Schrödinger’s platform to enable the rapid design of differentiated molecules and the impact that our computational approach can have on a drug discovery and development program.”
