Spots Global Cancer Trial Database for Blinatumomab Plus HLA-Mismatched Cellular Therapy for Relapsed/Refractory CD19+ ALL

Study Description

Brief Summary: Single center Phase 1 dose escalation trial of the combination of standard-of-care blinatumomab plus Haplo-Mismatched Cellular Therapy (HMCT). HMCT refers to the infusion of donor peripheral blood mononuclear cells collected via pheresis from a haploidentical family member - the procedure is analogous to giving a donor lymphocyte infusion outside of the setting of an allogeneic stem cell transplant; also known as 'microtransplantation'. The HMCT is an unselected mix of lymphocytes and leukocytes, but the product dose escalation will be done based on the T cell content. Ten recipients are planned. Each subject will be administered one infusion of HMCT during the first cycle of blinatumomab and two infusions during cycle two of blinatumomab; the CD3+ cell dose of the HMCT infusion is governed by dose escalation / de-escalation following a Bayesian method.

Detailed Description: This single center, phase 1 study will examine the safety, side effects, and effectiveness of combining the investigational use of Haplo-Mismatched Cellular Therapy (HMCT) in combination with blinatumomab. Investigators plan to give HMCT starting on day 15, after the initial CRS caused by blinatumomab has resolved. The investigational treatment will start with 1% of the typical HMCT dose (10e6 CD3+ cells/kg) and will employ a modified dose escalation design as an additional safety measure. The primary end points will be DLT of the combination of blinatumomab and HMCT.
