Study of 3D189 in Patients With Hematologic Malignancies

This is a phase 1, open-label, non-comparative, multicenter study of 3D189 (also known as galinpepimut-S), a multivalent peptide vaccine targeting Wilms Tumor-1 (WT1), for maintenance immunotherapy in patients with WT1-positive hematological malignancies, including patients with acute leukemia (AL) patients in complete remission (CR), or multiple myeloma (MM), non-Hodgkin lymphoma (NHL) or higher-risk myelodysplastic syndrome (MDS) patients who have received at least first-line standard therapy and recently achieved CR or partial remission (PR), if the latter is the best achievable response for the patient.
