About SELLAS’ WT1 Immunotherapeutic Anti-cancer Treatment, Galinpepimut-S

SELLAS’ WT1 immunotherapeutic anti-cancer treatment (generically designated as galinpepimut-S) is a late clinical-stage cancer immunotherapy being developed to target hematologic cancers and solid tumors, including acute myeloid leukemia (AML), mesothelioma (MPM), multiple myeloma, ovarian cancer, and multiple other cancers. The WT1 antigen is a transcription factor that is not generally expressed in normal adult cells, but appears in a large number of cancers, as well as in certain cancer stem cells. WT1 has been ranked by the National Cancer Institute (NCI) as the Number 1 target for cancer immunotherapy. While WT1 has not been druggable by traditional approaches, it can be targeted by the immune system. Specifically, a number of different peptide sequences from the WT1 antigen have been identified as immunogenic and capable of stimulating cytotoxic T-cells that can target and kill WT1-expressing cancer cells. Studies also have shown that WT1 does not provoke tolerization and that patients’ T-cells can remain reactive to the antigen over time.

Galinpepimut-S, originally developed by MSK and licensed to SELLAS, comprises four modified heteroclitic peptide chains that induce a strong innate immune response (CD4+/CD8+ T-cells) against the WT1 antigen. Galinpepimut-S is administered in combination with an adjuvant and an immune modulator to improve the immune response to the target. Based on its mechanism and the accumulating evidence of activity in mid-stage trials, galinpepimut-S may have the potential to complement currently available therapies by destroying residual tumor cells of cancers in remission and providing ongoing immune surveillance for recurrent tumors. Overall, SELLAS’ galinpepimut-S could target over 20 cancers that over-express WT1, many of which are associated with relapse rates of up to 80% or more, as seen in patients with AML and MPM.
