AstraZeneca’s busiAstraZenecapment team has landed anotherKRASet in its new favorite hunting grounds. Partnering with a Chinese biotech once again, the Anglo-Swedish drugmaker has secured a spot in the congested KRAS G12D space in exchange for $24 million upfront.
AstraZenecaves AstraZeneca a global license to UA022, a small molecule inhibitor of the once-undruggable oncogene that was in preclinical development at Usynova. The Chinese biotech discovered and advanced the moKRAS G12D collaboration with partners including WuXi AppTec, before deciding that AstraZeneca’s offer, which includes up to $395 million in milestones, was too good to turn down.
