A Phase 1 Study to Evaluate the Safety and Tolerability of a Combination Autologous CD19 CAR T Cell Therapy (SYNCAR-001 + STK-009) in Subjects With Relapsed or Refractory CD19+ Hematologic Malignancies

Description

This is a first-in-human phase 1 study of SYNCAR-001 + STK-009 in patients with CD19+ hematologic malignancies.SYNCAR-001 + STK-009 is a 2-component human orthogonal (ho) IL-2 receptor-ligand cell therapy consisting of (1) SYNCAR-001, a CD19-directed chimeric antigen receptor T cell (CAR-T) co-expressing an engineered IL-2 beta receptor (hoRb); and (2) STK-009, an engineered pegylated IL-2 cytokine (hoIL-2) selective for hoRb. The study will follow a 3+3 design during dose escalation. Cohort A will enroll subjects to SYNCAR-001 + STK-009 with lymphodepletion. At Dose Level 3, a separate dose escalation cohort will be introduced to enroll subjects to SYNCAR-001 + STK-009 without lymphodepletion (Cohort B). Subsequent dose expansions will enroll subjects at the RP2D for each cohort.

Trial Eligibility

Selected Inclusion Criteria: 1. Histologically confirmed relapsed/refractory hematologic malignancies, including Chronic Lymphocytic Lymphoma (CLL/SLL) and selected Non-Hodgkin's Lymphoma (NHL) 2.

No signs of symptoms of central nervous system (CNS) disease or detectable evidence of CNS or meningeal disease on magnetic resonance imaging (MRI) at the time of screening Selected Exclusion Criteria: 1. Prior CD19 directed therapy including CD19 CARTs 2. Prior allogeneic hematopoietic stem cell transplant within 6 months of enrollment 3. Prior autologous hematopoietic stem cell transplant within 6 weeks of enrollment. 4. Presence of GVHD
