Study Title

A Phase 1/2 Multicenter Study Evaluating the Safety and Efficacy of KTE-C19 in Adult Subjects with Relapsed/Refractory Chronic Lymphocytic Leukemia



Primary objective of Phase 1: Evaluate the safety of KTE-C19 in subjects with r/r CLL. Primary objective of Phase 2: Evaluate the efficacy of KTE-C19 as measured by the objective response rate (ORR) per independent review in subjects with r/r CLL treated with KTE-C19. Secondary objectives are to characterize the safety profile and assess additional efficacy endpoints including complete response (CR/CRi) rate, minimal residual disease negativity (MRD-) rate, CR/CRi with MRD- (CR/MRD-) rate, the duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Additional objectives will include evaluation of exploratory biomarker, pharmacokinetic and pharmacodynamic endpoints

Inclusion Criteria

  • History of autoimmune disease resulting in end-organ injury unless attributable to CLL (eg, idiopathic thrombocytopenic purpura (ITP), autoimmune hemolytic anemia (AIHA))
  • Diagnosis of Richter's transformation or a history of malignancy other than non-melanoma skin cancer or carcinoma in situ (eg, skin, cervix, bladder, breast), superficial bladder cancer, asymptomatic localized low grade prostate cancer for which watch-and-wait approach is standard of care, or any other cancer that has been in remission for > 3 years prior to enrollment
