A Phase 1/2 Multicenter Study Evaluating the Safety and Efficacy of KTE-X19 in Adult Subjects With Relapsed/Refractory Chronic Lymphocytic Leukemia (ZUMA-8)

The primary objective of this study is to evaluate the safety (Phase 1) and efficacy (Phase 2) of KTE-X19 in adults with relapsed/refractory chronic lymphocytic leukemia (r/r CLL).

Criteria

Key Inclusion Criteria:

  • Documentation of relapsed or refractory CLL; must have received at least 2 prior lines of treatment, one of which must include a Bruton's tyrosine kinase (BTK) inhibitor.
  • An indication for treatment per IWCLL 2018 criteria and radiographically measurable disease (at least 1 lesion > 1.5 cm in diameter)
  • 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
    • Baseline oxygen saturation > 92% on room air
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • At least 2 weeks or 5 half-lives, whichever is shorter, must have elapsed since any prior systemic therapy or BTKi (ibrutinib or acalabrutinib) at the time the subject is planned for leukapheresis, except for systemic inhibitory/stimulatory immune checkpoint therapy. At least 3 half-lives must have elapsed from any prior systemic inhibitory/stimulatory immune checkpoint molecule therapy at the time the subject is planned for leukapheresis (eg, ipilimumab, nivolumab, pembrolizumab, atezolizumab, OX40 agonists, 4-1BB agonists)

Key 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
  • History of severe hypersensitivity reaction attributed to aminoglycosides

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
