Schrödinger to Present New Preclinical SGR-3515 and PRMT5-MTA Data at 2024 EORTC-NCI-AACR Symposium

Schr�dinger (Nasdaq: SDGR) today announced that new preclinical data on SGR-3515, its investigational Wee1/Myt1 inhibitor, and the company’s PRMT5-MTA inhibitor program, will be presented during poster sessions at the 36th EORTC-NCI-AACR Symposium (ENA 2024) taking place October 23-25, 2024 in Barcelona, Spain.

The SGR-3515 presentation will include data further characterizing SGR-3515 in preclinical oncology models. Wee1 and Myt1 kinases regulate the cell cycle and DNA damage response, allowing time for DNA repair before cell division takes place. Concurrent loss of function or inhibition of Wee1 and Myt1 confers selective vulnerability in cancer cells, a mechanism referred to as synthetic lethality. The preclinical data indicate that SGR-3515 has a differentiated profile and support its continued development as a potential therapy for patients with advanced solid tumors. A Phase 1 clinical trial in this patient population is ongoing.

Additionally, preclinical data will be presented on the discovery of highly selective PRMT5-MTA inhibitors. Schr�dinger has identified a novel series of selective, potent PRMT5-MTA inhibitors and is optimizing lead compounds for use in peripheral and brain tumors.

Details of the data presentations are as follows:
