The United States Food and Drug Administration (FDA) has granted investigational new drug (IND) clearance for ALLO-501, an allogeneic anti-CD19 monoclonal chimeric antigen receptor T-cell (CAR-T) therapy drug candidate developed by Allogene Therapeutics in collaboration with Servier Laboratories, to be evaluated in patients with relapsed/refractory non-Hodgkin lymphoma (NHL).1

“Off-the-shelf” allogeneic CAR-T therapies derived from healthy donors are being investigated to potentially circumvent some of the recognized limitations of autologous CAR-T therapy, including potentially long wait periods for T cells to be collected and processed.2

In the upcoming phase 1 ALPHA trial, ALLO-501, designed to target CD19-positive malignancies, will be administered to up to 24 patients with the most common subtypes of NHL, relapsed/refractory diffuse large B-cell lymphoma or follicular lymphoma, following preconditioning chemotherapy with fludarabine/cyclophosphamide to deplete lymphocytes.

Patients will also receive pretreatment with ALLO-647, an investigational anti-CD52 monoclonal antibody (also manufactured by Allogene) that is thought to prevent host T cells expressing CD52 from rejecting ALLO-501.1
