Positive Ph 2 Preliminary Data of SLS009 in R/R AML Achieving a 100% Response Rate in Patients with ASXL1 Mutation at the Optimal Dose Level Announced

“The remarkable responses achieved in patients with the ASXL1 mutation underscores the transformative potential of SLS009 in addressing the unmet medical needs of AML but also targeting colorectal cancer, and other tumor types with this alteration,” said Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS. “This is evidenced by strong enthusiasm from the participating investigators reflected in robust enrollment from the clinical sites. These compelling results from the Phase 2a study further reinforce our belief that SLS009 represents a potential breakthrough for relapsed and/or refractory AML patients, and could pave the way for a potential accelerated approval in this defined patient population.”
