NEW YORK, Dec. 10, 2024 (GLOBE NEWSWIRE) -- SELLAS Life Sciences Group, Inc. (NASDAQ: SLS) (“SELLAS’’ or the “Company”), a late-stage clinical biopharmaceutical company focused on the development of novel therapies for a broad range of cancer indications, today announced that the pre-specified threshold of 60 events (deaths) has been reached in its ongoing Phase 3 REGAL clinical trial of galinpepimut-S (GPS) in acute myeloid leukemia (AML), triggering the interim analysis to be conducted by the Independent Data Monitoring Committee (IDMC).
The IDMC will conduct a thorough review of the current REGAL data, and the interim analysis will provide an assessment of efficacy, futility as well as safety of GPS.
“This is an exciting and very important milestone in our efforts to bring forward a new potential treatment option for AML patients,” said Angelos Stergiou, MD, ScD hc, President and Chief Executive Officer of SELLAS. “Our mission at SELLAS is to develop novel therapies that prolong patients’ lives, and the outcome of the interim analysis will hopefully bring us closer to the potential of adding GPS as a powerful ally in the battle against AML. Today, we are here thanks to the unwavering support of our shareholders, dedication of our clinical investigators and the resilience of our patients and their families. The IDMC will now carefully review and analyze all the data and have scheduled a meeting in January to review results to date. We are extremely grateful to everybody who have contributed to the REGAL study, and we look forward to sharing the IDMC’s feedback and recommendations as soon as they become available.”
The Company will host a call today to review the process leading up to the IDMC meeting and the potential outcomes of the REGAL interim analysis.

About SELLAS Life Sciences Group, Inc.
SELLAS is a late-stage clinical biopharmaceutical company focused on the development of novel therapeutics for a broad range of cancer indications. SELLAS’ lead product candidate, GPS, is licensed from Memorial Sloan Kettering Cancer Center and targets the WT1 protein, which is present in an array of tumor types. GPS has the potential as a monotherapy and combination with other therapies to address a broad spectrum of hematologic malignancies and solid tumor indications. The Company is also developing SLS009 (formerly GFH009) - potentially the first and best-in-class differentiated small molecule CDK9 inhibitor with reduced toxicity and increased potency compared to other CDK9 inhibitors. Data suggests that SLS009 demonstrated a high response rate in AML patients with unfavorable prognostic factors including ASXL1 mutation, commonly associated with poor prognosis in various myeloid diseases.

About the GPS Phase 3 REGAL Study
REGAL is a Phase 3 open-label registrational clinical trial for GPS in AML patients who have achieved complete remission following second-line salvage therapy (CR2 patients). The primary endpoint is overall survival. The IDMC is an independent group of medical, scientific, and biostatistics experts who are responsible for reviewing and evaluating patient safety and efficacy data for REGAL, and for monitoring quality and overall conduct to ensure the validity, scientific and clinical merits of the study. The IDMC charter provides for periodic reviews of safety, efficacy, and futility in addition to the interim and final analyses.
