Product Description
SELLAS' lead product candidate, galinpepimut-S (GPS), targets malignancies and tumors characterized by an overexpression of the WT1 antigen. SELLAS' WT1 immunotherapy is comprised of four peptide chains, two of which are modified chains that induce a strong innate immune response (CD4+/CD8+) against the WT1 antigen and access a broad range of HLA types. When administered to a patient, GPS' induced immune response has the potential to recognize and destroy cancer cells and provide ongoing support and memory to the immune system so that it can continue to target and destroy recurring tumors and residual cancer cells.
