Verve Therapeutics Inc. has packed a lot into the past few weeks. The latest is a four-year research deal with Vertex Pharmaceuticals Inc. to find and develop an in vivo gene editing program for an undisclosed liver disease. Vertex will pick up the tab for program costs as Verve does the preclinical R&D. Verve is getting an up-front $60 million from Vertex, along with a $35 million equity investment.
