A Pediatric and Young Adult Trial of Genetically Modified T Cells Directed Against CD22 for Relapsed/Refractory Leukemia or Lymphoma (NCT04571138)

Pediatric and Young Adult Leukemia Adoptive Therapy (PLAT)-07: A Phase 1/2 Study of CD22-Specific CAR T Cells for CD22+ Leukemia or Lymphoma

๐Ÿ”ต Active, Not Recruiting Phase1 / Phase2 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Seattle Children's Hospital

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

Patients with relapsed or refractory leukemia or lymphoma are often refractory to further chemotherapy. In this study, the investigators will attempt to use T cells obtained directly from the patient, which can be genetically engineered to express a chimeric antigen receptor (CAR). The CAR used in this study can recognize CD22, a protein expressed on the surface of leukemia and lymphoma cells. The phase 1 part of this study will determine the safety and appropriate dose level of these CAR T cells, and the phase 2 part of the study will determine how effective this CAR T cell therapy is. Both patients who have never had prior CAR T cell therapy and those who have had prior CAR T cell therapy may be eligible to participate in this study.
