E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is ORR, as determined by the IRRC, defined as the proportion of subjects achieving the best response rating of CR or PR based on the Modified Lugano Classification. ORR will be also be assessed by the Investigator as a secondary endpoint. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary analysis of ORR for FL will be triggered after the initial 91 consecutive subjects randomized to or assigned to IRS arm , which represents the Primary Efficacy Population (PEP) (except those who discontinue early), have been followed for at least 6 months from the start of study drug.
The primary analysis for MZL will be triggered after all subjects in ITT MZL population enrolled in the study (except those who discontinue early) have been followed for at least 6 months from the start of study drug. |
|
E.5.2 | Secondary end point(s) |
1. Duration of Response (DOR) and Duration of Recaptured Response (DORR) Duration of response (DOR) will be evaluated as a secondary endpoint and is defined as time from documentation of the first CR or PR to the time of first disease progression based on the Modified Lugano Response Criteria. To evaluate the duration of response for subjects who had recapture of response on the CS dosing, duration of recaptured response (DORR) is defined as the time from recapture of response to the time of second disease progression. These endpoints will be assessed by the IRRC and Investigator independently. 2.Progression-Free Survival (PFS) PFS will be assessed as a secondary endpoint and is defined as time from initiation of treatment (Day 1) until first disease progression or death from any cause. Disease progression criteria are defined per Modified Lugano Response Criteria and will be assessed by the IRRC and Investigator independently. 3. Time to treatment Failure (TTF) Time to treatment failure will be assessed as a secondary endpoint and is defined as the time from first dose of study drug to treatment failure. Treatment failure is defined as any treatment discontinuation due to disease progression, toxicity, or death. 4. Recapture of Response Recapture of response is defined as achieving a second documented CR or PR after experiencing the first PD. Recapture of response rate will be assessed by the IRRC and Investigator independently as a secondary endpoint, and is defined as the proportion of subjects who achieved a CR or PR followed by a PD during IS dosing and subsequently switched to CS dosing and achieved a second documented CR or PR. Time to recapture of response will be assessed as a secondary endpoint, and is defined as the time from the first PD until the second documented CR or PR. 5. Overall Survival (OS) OS will be assessed as a secondary endpoint and is defined as time from initiation of treatment (Day 1) until death from any cause independently from the study period or dosing schedule. OS time will be censored at the last date the subject is known to be alive when the confirmation of death is absent or unknown. |
