“SLS009 is a novel and highly selective CDK9 inhibitor which, to date, has shown tremendous therapeutic promise across multiple blood cancers,” said Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS. “We are pleased with the initiation of the Phase Ib/II trial of SLS009 in the underserved PTCL patient population. Collaborating with GenFleet amplifies the potential of our highly selective CDK9 inhibitor in multiple indications and reflects our joint commitment to delivering this groundbreaking treatment to cancer patients globally. While our primary efforts are focused on acute myeloid leukemia (AML) in the United States, we remain fully supportive and deeply involved in the PTCL study and will make further development decisions for this indication as we obtain initial data for this Phase Ib/II study from our partner.”
