GSK Signs $750m Chimagen TCE Deal for Multiple
GSK has signed a $750m deal with Chimagen Biosciences for global rights to a TCE for multiple myeloma. The agreement includes upfront and milestone payments, with Phase I trials planned for 2027. This follows GSK's 2015 exit from oncology and a 2024 deal with Chimagen for another TCE. Multiple myeloma is a significant market, with the US TCE market projected to exceed $10bn by 2032.
