Gene therapy developer Beam Therapeutics Inc. has acquired drug delivery specialist Guide Therapeutics Inc. in a deal valued at up to $440 million, adding yet another piece of the integrated platform CEO John Evans told BioWorld the company is striving to build. Guide's lipid nanoparticle (LNP) screening technology could help medicines developed by Beam and its partners reach new targets beyond the liver, an increasingly important endeavor for gene therapy developers like Beam, seeking to maximize the breadth of their growing portfolios. Terms of the deal included $120 million up front, plus up to $320 million in stock-based technology and product success milestone payments. Shares in Beam (NASDAQ:BEAM) fell 12.6% to $96.48 on Feb. 23.
