10. Male patients are eligible if vasectomized or if they agree to the use of barrier contraception with other methods described above during the study treatment period and for = 90 days after the last dose of zanubrutinib or 3 months after the last dose of bendamustine whichever is longer.
11. Ability to provide written informed consent and can understand and comply with the requirements of the study
12. Must have FISH results from the study-specified central laboratory confirming the presence or absence of del17p.
