Alphageneron Pharmaceuticals Inc., of Cambridge, Mass., said it signed an exclusive license agreement with Multimmune GmbH, of Munich, Germany, for its clinical-stage autologous NK cell therapy and companion diagnostic platform for all fields worldwide. The autologous NK cell therapy redirects NK cells to target a cell membrane form of heat-shock protein 70, which has been discovered to be highly expressed on many cancer cells but not on healthy cells, according to Alphageneron. The company will pay Multimmune an unnamed amount in developmental and regulatory milestones, plus post-commercialization royalties. In July, the two companies signed a collaboration agreement to repurpose the NK cell therapy platform for treating SARS-COV-2.
