All study participants must be registered into the mandatory RevAssist program, and be willing and able to comply with the requirements of RevAssist

Exclusion Criteria:

• Documented prolymphocytic leukemia (prolymphocytes more than 55% in the blood)
• Known positivity for human immunodeficiency virus (HIV) or active hepatitis B or C. Positive serology for hepatitis B (HB) defined as a positive test for hepatitis B surface antigen (HBsAg). In addition, if negative for HBsAg positive but HBcAb positive regardless of HBsAg status, a HB deoxyribonucleic acid (DNA) test will be performed and if positive the subject will be excluded
