Details and patient eligibility

About

All participants will receive rilzabrutinib orally. The screening period is up to 28 days, followed by a treatment period of 24 weeks for Part A. Participants who complete Part A and are deemed eligible for Part B can continue in the Core Part B period followed by an Extended Part B period for up to 253 weeks.

There will be a 7-day safety follow-up period after receiving the last dose of study medication either in Part A (for those not eligible for Part B or early terminated) or Part B. In addition, each participant will be asked to attend an EOT-Core Part B visit when the last participant completes 52 weeks in Core Part B. The Extended Part B period will last for up to 253 weeks.
