STX-478

The pharmaceutical sector has seen significant advancements with FDA approvals for new treatments and the initiation of clinical trials for innovative therapies. Notably, Eli Lilly's Omvoh has been approved for Crohn's disease, and Johnson & Johnson is advancing its TAR-200 for bladder cancer treatment. These developments underscore the industry's commitment to addressing unmet medical needs through research and innovation.

Eli Lilly is set to acquire Scorpion Therapeutics' PI3Kα inhibitor program, including STX-478, currently in Phase I/II trials, for up to $2.5 billion.

Allosteric PIK3CA inhibitors, like STX-478 and RLY-2608, offer a more targeted approach with improved safety profiles compared to orthosteric inhibitors.

STX-478, an oral PI3Kα inhibitor, demonstrated anti-tumor activity in a Phase 1/2 trial, with an overall response rate of 23% in breast cancer patients.
