Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is to evaluate the efficacy of KTE-X19, as measured by objective response rate, in subjects with r/r MCL. ;Secondary Objective: Secondary objectives will include assessing the safety and tolerability of KTE-X19, and additional efficacy endpoints, including duration of response (DOR). Secondary objectives related to patient-reported outcomes (PROs) in Cohort 1 and Cohort 2 will include change in the European Quality of Life-5 Dimensions (EQ-5D) scores from baseline to Month 6. Secondary objectives related to PROs in Cohort 3 will include change in EQ-5D and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) scores from baseline over time.;Primary end point(s): Objective response rate [ORR] (complete response [CR] + partial response [PR]) per the Lugano Classification (Cheson et al, 2014) per Independent Radiology Review Committee (IRRC) review.;Timepoint(s) of evaluation of this end point: The primary analysis in Cohort 1 will be performed after 60 KTE-X19 subjects in the mITT set of Cohort 1 have been enrolled and treated with KTE-X19 and have had the opportunity to be evaluated for response 6 months after the Week 4 disease assessment. The primary analysis in Cohort 3 will occur after 86 subjects in Cohort 3 have been enrolled and treated with KTE-X19 and have had the opportunity to be assessed for response 6 months after the first objective response or 9 months after the KTE-X19 infusion, whichever is earlier. A follow-up analysis will be performed after 86 subjects in Cohort 3 have had the opportunity to be assessed for response 18 months after the first objective response to further evaluate the risk-benefit profile of KTE-X19, including the durability of response. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Duration of Response - Best Objective Response - Objective response rate as determined by study investigators - Progression Free Survival - Overall Survival - Incidence of adverse events and clinically significant changes in laboratory values -Incidence of anti-CD19 CAR antibodies - Levels of anti-CD19 CAR+ T cells in blood - Levels of cytokines in serum - Changes over time in the EQ-5D scale score and visual analogue scale score - Changes over time in the EORTC-QLQ-C30 score (Cohort 3 only);Timepoint(s) of evaluation of this end point: All enrolled subjects will be followed in the long term follow-up period for survival and disease status if applicable. Subjects will begin the long term follow-up period after they have completed the Month 3 visit of the post treatment assessment period (whether they have responded to treatment or went straight to the month 3 visit due to disease progression) - Every 3 months (± 2 weeks) through Month 18 (for Cohort 1 and Cohort 2) or through Month 21 (for Cohort 3) - Month 24 (± 1 month) - Beginning with Protocol Amendment 8 and after completion of at least 24 months of assessments in KTE-C19-102, subjects who received an infusion of anti-CD19 CAR T cells will be given the opportunity to transition to a separate LTFU study, KT-US-982-5968, after providing signed informed consent. | — |
