9. Men who are sexually active and can beget children must agree to use highly effective
forms of contraception during the study and for 90 days after the last dose of

the last dose of idelalisib, 6 months after the last dose of bendamustine, or 12
months after the last dose of rituximab, whichever is longer.

study protocol, including swallowing capsules without difficulty.
