E.4 | Principal exclusion criteria |
1. Previous treatment with ofatumumab. 2. Previous anti-CD20 radioimmunotherapy (RIT), or non-rituximab anti-CD20 therapy (such as obinutuzumab) within 6 months prior to randomization. Patients who have received previous anti-CD20 RIT or non-rituximab anti-CD20 therapy (such as obinutuzumab) must have attained a partial or complete response lasting at least 6 months, and must have recovered from any hematologic or other toxicity. 3.

ALT or AST > 3xULN d. Alkaline phosphatase > 1.5xULN (unless due to lymphoma or a non-malignant, non-hepatic cause such as Paget’s disease) e. Total bilirubin > 1.5xULN (unless due to lymphoma or isolated, predominantly indirect hyperbilirubinemia due to Gilbert’s syndrome) 12. Known or suspected inability to fully comply with study protocol 13. Because the effects of ofatumumab on fetuses and nursing infants are not known, the following are ineligible for study entry: a. Lactating women. b. Women with a positive pregnancy test at study entry c.
