施罗德从布里斯托尔收回抗癌药物候选权

2024-05-03 03:04

  • Bristol-Myers Squibb (NYSE:BMY) has returned the rights to a preclinical cancer drug candidate, an SOS1 inhibitor, back to Schrodinger (NASDAQ:SDGR).
  • Schrodinger noted that it delivered a development candidate, and Bristol had been conducting IND-enabling studies on it.
  • The two companies began their collaboration in 2020, which included a $55M upfront payment from Bristol and up to $2.7B in milestones. An immunology target and a neurology target that are part of that agreement are not impacted.
  • Part of the reason why Bristol (BMY) may have returned the candidate is that it gained an SOS1 inhibitor, MRTX0902, currently in phase 1, through its recent $4.8B acquisition of Mirati Therapeutics.
  • SOS1 is a protein that regulates the ability of the KRAS gene to cycle through "on" and "off" stages. KRAS mutations are involved in about one-third of cancers.
