A Study to Compare the Efficacy and Safety of JCAR017 to Standard of Care in Adult Subjects With High-risk, Transplant-eligible Relapsed or Refractory Aggressive B-cell Non-Hodgkin Lymphomas

Overview

The study will be conducted in compliance with the International Council for Harmonisation (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use/Good Clinical Practice (GCP) and applicable regulatory requirements.

This is a randomized, open-label, parallel-group, multi-center trial in adult subjects with Relapsed or refractory (R/R) aggressive Non-Hodgkin lymphoma (NHL) to compare safety and efficacy between the standard of care (SOC) strategy versus JCAR017 (also known as lisocabtagene maraleucel or liso-cel). Subjects will be randomized to either receive SOC (Arm A) or to receive JCAR017 (Arm B).

All subjects randomized to Arm A will receive Standard of care (SOC) salvage therapy (R-DHAP, RICE or R-GDP) as per physician's choice before proceeding to High dose chemotherapy (HDCT) and Hematopoietic stem cell transplant (HSCT).

Subjects from Arm A may be allowed to cross over and receive JCAR017 upon confirmation of an EFS event.

Subjects randomized to Arm B will receive Lymphodepleting (LD) chemotherapy followed by JCAR017 infusion.

Clinical Trial Outcome Measures

Primary Measures

  • Event-free survival (EFS)
    • Time Frame: Approximately 3 years
    • Time from randomization to death from any cause, progressive disease (PD), failure to achieve complete response (CR) or partial response (PR), or start of new antineoplastic therapy due to efficacy concerns, whichever occurs first

Secondary Measures

  • Complete response rate (CRR)
    • Time Frame: Approximately 3 years
    • Percentage of subjects achieving a complete response (CR)
  • Progression-free survival (PFS)
    • Time Frame: Approximately 3 years
    • Time from randomization to PD or death from any cause, whichever occurs first
  • Overall survival (OS)
    • Time Frame: Approximately 4.5 years
    • Time from randomization to time of death due to any cause
  • Overall response rate (ORR)
    • Time Frame: Approximately 3 years
    • Percentage of subjects achieving an objective response of partial response (PR) or better according to the Lugano Classification as assessed by IRC review
  • Duration of response (DOR)
    • Time Frame: Approximately 3 years
    • Time from first response to disease progression, start of new antineoplastic therapy due to efficacy concerns or death from any cause
  • PFS on next line of treatment (PFS-2)
    • Time Frame: Approximately 3 years
    • Time from randomization to second objective disease progression or death from any cause, whichever is first.
  • Adverse Events (AEs)
    • Time Frame: Approximately 3 years
    • Type, frequency and severity of adverse events (AEs), serious adverse events (SAE), and laboratory abnormalities (overall and in clinical, histological and molecular subgroups)
  • HRQoL using European Organisation for Research and Treatment of Cancer – Quality of Life C30 questionnaire (EORTC-QLQ-C30)
    • Time Frame: Approximately 3 years
    • European Organisation for Research and Treatment of Cancer – Quality of Life C30 questionnaire: The EORTC QLQ-C30 questionnaire will be used as a measure of health-related quality of life, fatigue, physical and cognitive functions.
  • HRQoL parameters assessed by FACT-Lym “Additional concerns” subscale
    • Time Frame: Approximately 3 years
    • Functional Assessment of Cancer Therapy-Lymphoma “Additional concerns” subscale: Only the LYM subscale will be administered in this study. This scale addresses symptoms and functional limitations (15 item) that are important to lymphoma patients.
  • Reasons for hospital resource utilization

  • Frequency of hospital resource utilization
    • Time Frame: Approximately 3 years
    • Will be assessed based on frequency of hospitalizations calculated as, inpatient days, intensive care unit (ICU) days, outpatient visits days
  • Hospital resource utilization (HRU)
    • Time Frame: Approximately 3 years
    • Will be assessed based on frequency of hospitalizations calculated as, inpatient days, intensive care unit (ICU) days, outpatient visits days and reasons for hospitalization
