E.3 | Principal inclusion criteria |
1. Active, histologically proven B-cell NHL that is generally regarded as indolent (eg FL, marginal zone lymphoma, lymphoplasmacytic lymphoma) that is also determined to be high risk as defined by one or more of the criteria below:
o Progression of B-cell iNHL within 24 months of original diagnosis of disease that was subsequently treated with first-line anti-CD20 monoclonal antibody- and cytotoxic agent-containing combination chemoimmunotherapy (eg, R-CHOP, R-Bendamustine, R-CVP, R-fludarabine).

E.5 End points |
E.5.1 | Primary end point(s) |
ORR is defined as the incidence of a CR or a PR by the revised IWG Response Criteria for Malignant Lymphoma as determined by the study investigators. All subjects who do not meet the criteria for an objective response by the analysis cutoff date will be considered non-responders. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary efficacy analysis of response rate will be performed when the last treated subject has had the opportunity to be evaluated for response 6 months after the axicabtagene ciloleucel infusion. An additional analysis of 12-month PFS will occur after the last treated subject has had the opportunity to be evaluated for response 12 months after the axicabtagene ciloleucel infusion. The CSR will be written based on the data collected and analyzed from this additional analysis. Additional descriptive analyses may occur after the primary analysis as needed. The final analysis will occur when all subjects have completed the study. |
|
E.5.2 | Secondary end point(s) |
PFS is defined as the time from the axicabtagene ciloleucel infusion date to the date of disease progression per the revised IWG Response Criteria for Malignant Lymphoma or death from any cause. Subjects not meeting the criteria for progression by the analysis data cutoff date will be censored at their last evaluable disease assessment date. Subjects who receive additional anti-cancer therapy (with the exception of stem cell transplant) in the absence of documented progression will be censored at the last evaluable disease assessment prior to the additional therapy. Death that occurs after additional anti-cancer therapy will be considered a PFS event.
The 12-month PFS rate is defined as the Kaplan-Meier estimate of PFS at 12 months post axicabtagene ciloleucel infusion. Best objective response is defined as the incidence of CR, partial PR, stable disease (SD), PD, or unevaluable (UE) as best response to treatment. Duration of Response (DOR) is defined for subjects who experience an objective response and is defined as the date of their first objective response (which is subsequently confirmed) to disease progression per the revised IWG Response Criteria for Malignant Lymphoma (Cheson 2007) or death from any cause. Subjects not meeting the criteria for progression or death by the analysis data cutoff date will be censored at their last evaluable disease assessment date. Subjects who receive additional anti-cancer therapy (with the exception of stem cell transplant) in the absence of documented progression will be censored at the last evaluable disease assessment prior to the additional therapy. Death that occurs after additional anticancer therapy will be considered an event. OS is defined as the time from axicabtagene ciloleucel infusion to the date of death. Subjects who have not died by the analysis data cutoff date will be censored at their last date known to be alive.
Other secondary endpoints are as follows: • Incidence of AEs. • Clinically significant changes in laboratory values. • Incidence of anti-axicabtagene ciloleucel antibodies. • Levels of anti-CD19 CAR T cells in blood. • Levels of cytokines in serum. |
|
E.5.2.1 | 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 • Every 6 months (± 1 month) between Month 24 to Month 60 |
