Description: SLS Sellas Life Sciences

SELLAS Life Sciences Group is a late-stage clinical biopharmaceutical company developing novel cancer therapeutics, with its lead candidates being galinpepimut-S (GPS), a peptide immunotherapy targeting the Wilms tumor 1 (WT1) antigen, and SLS009 (tambiciclib), a selective CDK9 inhibitor. The company operates in the high-risk, capital-intensive biotech model typical of clinical-stage oncology developers, where value is driven primarily by pipeline progress, clinical trial readouts, and partnership milestones rather than recurring product revenue. SELLAS has established strategic collaborations with Merck & Co. to evaluate GPS in combination with pembrolizumab across multiple cancer indications, with GenFleet Therapeutics for the development of GFH009, and with Memorial Sloan Kettering Cancer Center for WT1 peptide vaccine technology.

  • Merck collaboration advances GPS-pembrolizumab combination into multiple cancer indications
