Clinical Trials

Sponsored by Bayer, several clinical trials are evaluating the early-stage development of BAY 2965501 in patients with advanced solid tumors. These Phase 1 protocols assess the safety, tolerability, dosing parameters, and maximum tolerated dose of the compound, with recruitment spanning both actively recruiting and active, non-recruiting statuses. Together, these studies aim to establish the preliminary therapeutic profile of BAY 2965501 to support its continued development against solid malignancies.

Compliance for Clinical Use

Mechanism and Biochemical Profile

BAY 2965501 acts as a potent and selective inhibitor of diacylglycerol kinase zeta (DGKζ), preventing the phosphorylation of diacylglycerol and thereby restoring intracellular diacylglycerol levels in T-cells. This elevation in diacylglycerol induces downstream extracellular signal-regulated kinase (pERK) activation in anergic T-cells, enhancing immune cell reactivation to facilitate T-cell-mediated tumor cell killing in advanced solid tumors.
