July 16, 2024 -- 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 U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease Designation (RPDD) to SLS009, a highly selective CDK9 inhibitor, for the treatment of pediatric acute myeloid leukemia (AML). The FDA previously granted Orphan Drug and Fast Track Designations to SLS009 for the treatment of AML. “Receiving our second Rare Pediatric Disease Designation, following pediatric acute lymphoblastic leukemia last month, is another acknowledgment of SLS009’s novel transformational treatment potential to improve the lives of patients, including children with AML,” said Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS. ”This designation reinforces our dedication to addressing the urgent needs of children with AML, including those with treatment-resistant mutations, highlighting the promise of SLS009 to offer the specialized care and support they require, especially considering the limited treatment options for rare pediatric diseases. We look forward to continued SLS009 development and enrolling pediatric AML patients in our Phase 2 clinical trial.”
AML prognosis with currently available treatments in the refractory and/or relapsed pediatric patient population remains poor. In a representative study, the 5-year overall survival (OS) rate in relapsed pediatric AML was 33% for all patients, and in patients whose remission lasted less than 12 months only 15.7%. In patients who did not achieve complete remission after one course of chemotherapy 5-year overall survival was 0%. About 50% of children with pediatric AML relapse. Generally, the only therapy considered curative in relapsed and refractory patients is a bone marrow transplant and the primary goal of chemotherapy is to achieve remission so that pediatric patients can be transplanted.
Rare Pediatric Disease (RPD) Designation is granted by the FDA for serious or life-threatening diseases that affect fewer than 200,000 people in the United States and in which the serious or life-threatening manifestations primarily affect individuals less than 18 years of age. If, in the future, a New Drug Application (NDA) for SLS009 for the treatment of pediatric AML is approved by the FDA, SELLAS might be eligible to receive a Priority Review Voucher (PRV) that could be redeemed to receive a priority review for any subsequent marketing application. PRVs may be used by the sponsor or sold to another sponsor for their use and have recently sold for approximately $100 million.
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’ other 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.
