Repare Therapeutics Inc. recently shared phase I data from the Mythic gynecologic expansion trial, which assessed the combination of lunresertib and camonsertib at the recommended phase II dose in patients with endometrial cancer and platinum-resistant ovarian cancer. These patients harbored lunre-sensitizing biomarkers. Lunresertib is a first-in-class precision oncology small-molecule PKMYT1 inhibitor, designed to target cell cycle regulation in Lunre BM-positive tumors, specifically those with CCNE1 amplifications or FBXW7 or PPP2R1A deleterious alterations. Camonsertib is an oral small-molecule inhibitor of ATR, potentially best-in-class. The market responded negatively to the news, with Repare's shares (NASDAQ:RPTX) declining significantly.

CSPC will receive an initial payment of $150 million and is eligible for potential development milestone payments of up to $135 million, commercialization milestone payments reaching $1.5 billion, and sales-based royalties.
Novel Insulin Receptor Discovery
Researchers at the Helmholtz Institute have identified inceptor, a novel inhibitor of the insulin signaling pathway. This molecule functions by binding insulin and targeting it for degradation. According to Heiko Lickert, director of the Institute of Diabetes and Regeneration Research at Helmholtz Munich, this discovery marks a significant advancement in understanding insulin regulation, as inceptor represents a new insulin receptor that degrades insulin. The findings were published in Nature Metabolism.
