GSK agreed to acquire Chimagen's trispecific T cell-engager candidate for multiple myeloma, a drug asset the parties describe as a potential best in class trispecific T cell therapy. The deal expands GSK's blood cancer research portfolio and complements recent moves such as the Nuvalent acquisition that brought in Jideytro. Separately, GSK plans to close its German vaccine manufacturing site and consolidate production in Canada, with associated job reductions and supply chain changes. The key test will be whether GSK hits its stated timeline to move the trispecific T cell-engager into phase I trials in 2027, while advancing Jideytro's first line FDA submission planned for 2026. GSK is a £74.8b pharmaceuticals group that develops vaccines, specialty treatments and general medicines across major markets.
