Late-stage biopharmaceutical company, SELLAS Life Sciences Group, Inc. (Nasdaq: SLS) has announced positive topline data for the patient group with relapsed/refractory (r/r) lymphomas from its Phase 1 dose-escalation trial of its CDK9 inhibitor, SLS009 (GFH009).
“We are excited to share strong topline data from the Phase 1 trial of SLS009 in lymphoma patients. The data demonstrate meaningful anti-tumor activity and clinical responses as a monotherapy. Based on its favorable therapeutic profile, SLS009 continues to emerge as a potential treatment for patients with hematologic malignancies who have exhausted available treatment options.”
Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS
SELLAS’ partner, GenFleet Therapeutics, expects to advance GFH009 (SLS009) into Phase 2 clinical studies in China for patients with peripheral T-cell lymphoma (PTCL) later this year.
SELLAS’ study enrolled 52 r/r lymphoma patients. Among 34 evaluable patients, five (14.7%) achieved a clinical response with a reduction in tumor burden of up to 62% and an additional seven patients (20.6%) achieved stable disease resulting in an overall disease control rate of 35.3%.
The study established a recommended Phase 2 Dose (RP2D) for lymphoma patients at the highest dose level evaluated of 100 mg, administered as a once-weekly infusion.
All primary and secondary study objectives, including safety, clinical activity, pharmacokinetics (PK), and pharmacodynamics (PD), were successfully achieved.
