Experimental: Ibrutinib 420 milligram (mg)
Participants will receive ibrutinib 420 mg once daily, continuously starting at Day 1 of Week 1 until disease progression or unacceptable toxicity, whichever occurs first.
Ibrutinib will be administered orally, once daily, at a dose of 420 mg (140 mg*3 capsules taken together at one time).
- Overall Response Rate (ORR) [ Time Frame: Up to 4 years ]ORR is defined as the percentage of participants who achieve partial response (PR) or better per the modified Consensus Response Criteria from the 6th International Workshop on Waldenstrom Macroglobulinemia (IWWM) (NCCN 2019) as assessed by the investigator.
- Percentage of Participants Achieving Clinical Response Rate (CRR) [ Time Frame: Up to 4 years ]CRR is defined as the percentage of participants who achieve minor response (MR) or better according to the modified 4th IWWM (NCCN 2019) criteria as assessed by the investigator.
- Percentage of Participants Achieving Very Good Partial Response (VGPR) or Better Response [ Time Frame: Up to 4 years ]VGPR or better rate is defined as the percentage of participants who achieve VGPR or better according to the modified 4th IWWM (NCCN 2019) criteria as assessed by the investigator.
- Duration of Response (DOR) [ Time Frame: Up to 4 years ]DOR is defined as duration from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease or death for responders (PR or better) as assessed by the investigator.
- Time to Response (TTR) [ Time Frame: Up to 4 years ]TTR is defined as the time from the date of first dose to the date of initial documentation of a response (PR or better).
- Progression Free Survival (PFS) [ Time Frame: Up to 4 years ]PFS is defined as duration from the date of first dose to the date of disease progression or death, whichever is first reported, assessed according to the modified 6th IWWM (NCCN 2019) criteria.
- Overall Survival (OS) [ Time Frame: Up to 4 years ]OS is defined as the time from the date of first dose to the date of the participant's death from any cause.
- Trough Plasma Concentration (Ctrough) of Ibrutinib [ Time Frame: Day 1 of Weeks 1, 5 and 9 ]Ctrough is defined as the observed plasma concentration before dosing or at the end of the dosing interval.
- Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability [ Time Frame: Up to 4 years ]An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
