Safety and Efficacy of KTE-C19 in Adults With Relapsed / Refractory Chronic Lymphocytic Leukemia

Status: Active


The primary objective of this study is to evaluate the safety (Phase 1) and efficacy (Phase 2) of KTE-C19 in adults with relapsed / refractory chronic lymphocytic leukemia (r / r CLL).

Eligibility Criteria

Inclusion Criteria

  • Documentation of relapsed or refractory CLL AND a minimum of two prior treatment regimens with progression on treatment with ibrutinib

  • Adequate hematologic function as indicated by:
  • Platelet count ≥ 50 × 10^9/L
  • Neutrophil count ≥ 0.5 × 10^9/L
  • Hemoglobin ≥ 8 g/dL unless lower values are attributable to CLL
  • Adequate renal, hepatic, cardiac and pulmonary function defined as:
  • Creatinine clearance (as estimated by Cockcroft-Gault) ≥ 60 mL/min
  • Serum alanine aminotransferase (ALT)/aspartate aminotransferase (AST) ≤ 2.5 x upper limit of normal (ULN)
  • Total bilirubin ≤ 1.5 mg/dL unless subject has Gilbert's syndrome
  • Left ventricular ejection fraction (LVEF) ≥ 50%, no evidence of pericardial effusion, no New York Heart Association (NYHA) class III or IV functional classification, no clinically significant arrhythmias
  • No clinically significant pleural effusion

Exclusion Criteria

  • A history of treatment including any of the following:
  • Prior CD19 directed therapy
  • Prior allogeneic hematopoietic stem cell transplant (SCT) or donor lymphocyte infusion (DLI) within 6 months prior to enrollment
  • 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
