(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 Galinpepimut-S (GPS), an immunotherapeutic targeting Wilms Tumor-1 (WT1), for the treatment of pediatric acute myeloid leukemia (AML). “GPS has already demonstrated promise in clinical settings for AML, and we believe its potential could extend to pediatric patients,” said Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS. “Receiving RPDD from the FDA is another acknowledgment of the critical need for new treatment options for AML and our results in adult patients.

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...
