SELLAS Life Sciences Doses First Pediatric AML Patient in Trial
SELLAS Life Sciences Takes a Major Step in Pediatric AML Treatment
SELLAS Life Sciences Group, Inc. (NASDAQ: SLS) has reached a significant milestone by dosing the first pediatric patient in their ongoing Phase 2 trial of SLS009, a groundbreaking treatment aimed at relapsed/refractory acute myeloid leukemia (r/r AML). This development marks a notable advancement in their commitment to addressing critical needs in hematologic disorders, especially for younger patients.
The Significance of SLS009 in Pediatric AML
SLS009, also known as tambiciclib, is recognized as a highly selective CDK9 inhibitor. Its design intends to provide hope for children suffering from r/r AML, a condition with limited treatment options. Dragan Cicic, MD, Chief Development Officer of SELLAS, expressed excitement about this milestone, remarking on their commitment to finding effective therapies for patients facing significant challenges due to their condition.
Addressing Unmet Needs in Hematologic Disorders
The announcement underscores the company's dedication to the pediatric population, which often experiences a scarcity of effective treatment options. Children battling AML, particularly those with complex challenges such as multi-hit TP53 mutations and previous treatment failures, find themselves in urgent need of novel therapies. With SLS009's promising profile, SELLAS aims to fill this gap in critical care.
Trial Details and Potential Outcomes
The Phase 2 clinical trial is designed as an open-label, single-arm, multi-center study tasked with assessing the safety, tolerability, and efficacy of SLS009 in combination with venetoclax and azacitidine. Researchers are evaluating two dosage levels: 45 mg and 60 mg. The dosing strategy includes patients receiving either 60 mg once a week or a lower dose administered twice weekly.
Expanding the Study's Cohort
The trial expansion includes additional cohorts for patients with ASXL1-mutated AML and those carrying other myelodysplasia-related molecular abnormalities. SELLAS is aiming for a target response rate of 20% and a median survival of at least three months among study participants. Furthermore, this study seeks to identify biomarkers that could aid in selecting the most suitable patients for future treatments.
Regulatory Designations and Future Potential
In July 2024, SELLAS received FDA Rare Pediatric Disease Designation (RPDD) for SLS009. This designation opens the door for additional regulatory advantages and the potential for a Priority Review Voucher (PRV) should a New Drug Application (NDA) for pediatric AML be approved. PRVs can be immensely valuable, recently trading for approximately $100 million in the industry.
SLS009: A Leading Candidate in Oncology
SLS009 stands out as a potentially best-in-class CDK9 inhibitor, noted for its reduced toxicity and increased potency compared to existing treatments. As the company continues its mission to innovate therapies, SLS009 is positioned to make a meaningful impact in pediatric oncology.
