Schrödinger Highlights Discovery of SGR-1505, Clinical-Stage MALT1 Inhibitor, at American Chemical Society National Meeting

Schrödinger, Inc. (Nasdaq: SDGR), whose physics-based computational platform is transforming the way therapeutics and materials are discovered, today presented the discovery of SGR-1505, its MALT1 inhibitor, during the First Time Disclosure Session at the American Chemical Society (ACS) Spring 2024 Meeting. SGR-1505 is being evaluated in a Phase 1 dose-escalation study in patients with relapsed/refractory B-cell malignancies.

The oral presentation provided an overview of how Schrödinger leveraged its computational approaches at scale to discover SGR-1505. Schrödinger’s platform enabled vast exploration of chemical space, triaging 8.2 billion compounds, synthesizing 78 of the most promising molecules in the lead series, and identifying SGR-1505 as the company’s development candidate in approximately 10 months. Reaching a development candidate can take three to six years and typically involves synthesizing up to 5,000 molecules per program.

“Designing the optimal molecule is a tremendous multi-parameter optimization challenge that requires balancing many key properties,” stated Aleksey Gerasyuto, Ph.D., head of medicinal chemistry at Schrödinger. “One of our goals in this program was to address the limitations reported with other MALT1 inhibitors. By leveraging our computational platform, our cross-functional team simultaneously and rapidly optimized key drug-like properties and designed several distinct chemical series, ultimately selecting SGR-1505 as our development candidate.”

“We believe SGR-1505 has the potential to be a best-in-class compound. The preclinical profile of SGR-1505, coupled with positive data from our recently completed Phase 1 study in healthy subjects, further increases our conviction about our MALT1 program,” said Margaret Dugan, M.D., chief medical officer at Schrödinger. “Our Phase 1 study in patients with relapsed/refractory B-cell lymphomas is progressing well, and we look forward to reporting initial data from the study in late 2024 or 2025.”

SGR-1505 Clinical Studies

Schrödinger is conducting a Phase 1 dose-escalation study in patients with relapsed/refractory B-cell lymphomas to evaluate the safety, pharmacokinetics, pharmacodynamics and preliminary signals of therapeutic activity of SGR-1505 as a monotherapy. The study is enrolling patients at multiple sites in the U.S. and Europe. Once the recommended dose is determined, an expansion cohort is planned to evaluate SGR-1505 in combination with other anti-cancer agents, such as BTK and BCL-2 inhibitors, in patients with specific B-cell malignancies.

Schrödinger recently completed a Phase 1 study showing that SGR-1505 was well tolerated in a Phase 1 study of 73 healthy volunteers. No drug-related serious adverse events or dose limiting toxicities were observed in the study. The data also confirmed target engagement, with greater than 90 percent inhibition of IL-2 secretion in activated T cells, a pharmacodynamic goal of the study.
