- Status
- WITHDRAWN
- Sex
- All
- Target Recruitment
- Not specified
- Male and female participants aged 18 years or older. (Japan aged 20 years or older.)
- Have received no previous systemic anti-lymphoma therapies.
- Pathologically confirmed MCL by local laboratory.
- Histologically confirmed CD20 expression (by flow cytometry or immunohistochemistry) of the MCL cells as assessed by pathology.
- Ineligible for high-dose chemotherapy and autologous stem cell transplantation.
- Radiographically (CT, MRI) measurable lymphadenopathy per the Lugano criteria for response assessment (Cheson et al 2014).
- ECOG PS of 0 to 2.
- Willingness to avoid pregnancy or fathering children.
- Presence of any lymphoma other than MCL.
- Presence of CNS lymphoma (either primary or secondary) or leptomeningeal disease.
- Requires treatment with potent inducers and inhibitors of CYP3A4
- Inadequate organ functions including hematopoiesis, liver, and kidney significant concurrent, uncontrolled medical condition, including, but not limited to, renal, hepatic, hematological, GI, endocrine, pulmonary, neurological, cerebral, or psychiatric disease.
- History of other malignancy within 2 years of study entry.
- Known HIV infection, HBV or HCV.
- HBV or HCV infection: Participants positive for HBsAg or anti-HBc will be eligible if they are negative for HBV-DNA; these participants must receive prophylactic antiviral therapy. Participant's positive for HCV antibody will be eligible if they are negative for HCV-RNA.
- Clinically significant cardiac disease, congestive heart failure, including unstable angina, acute myocardial infarction, or cardiac conduction issues, within 6 months of randomization.
- Abnormal ECG findings that are clinically meaningful per investigator's assessment.
- Women who are pregnant or breastfeeding
- Any condition that would, in the investigator's judgment, interfere with full participation in the study, including administration of study treatment and attending required study visits; pose a significant risk to the participant; or interfere with interpretation of study data.

- Primary Outcome Measures
Name Time Method Progression Free Survival 7 years Defined as the time from the date of randomization until the date of first-documented disease progression, as determined by an Independent Review Committee (IRC) based on the Lugano criteria, or death from any cause, whichever happens first.
- Secondary Outcome Measures
Name Time Method Disease Control Rate 7 Years Defined as the proportion of participants who achieved a response of CR, PR, or Stable Disease (SD) assessed by an IRC.
Complete Response Rate 7 Years Defined as the proportion of participants with a CR as determined by an IRC- provided radiographic disease assessment of response according to response criteria for lymphomas.
Time To Next anti-Lymphoma Treatment 7 Years Defined as the time from date of randomization to date of first documented administration of a new anti-lymphoma treatment.
Duration of Response 7 Years Defined as the time from first-documented evidence of CR or PR until first documented disease progression or death from any cause, whichever happens first, among participants who achieve an objective response, as determined by radiographic disease assessment provided by an IRC.
Duration Of Complete Response 7 Years Defined as the time from the first evidence of CR to the date of first documented disease progression or death from any cause, whichever happens first, among participants who achieve a CR, as determined by radiographic disease assessment provided by an IRC.
Overall Survival 10 years Defined as the time from the date of randomization until death from any cause.
Event Free Survival 7 Years Defined as the time from date of randomization to date of first documented progression, as determined by radiographic disease assessment provided by an IRC, administration of a new anti lymphoma treatment, or death from any cause, whichever happens first.
Progression-Free Survival on next anti-lymphoma treatment 7 Years Defined as the time from the date of randomization to the date of first documented disease progression as reported by investigator after next anti-lymphoma treatment or death from any cause, or start of a third anti-lymphoma treatment since randomization, whichever happens first.
Objective Response Rate 7 Years Defined as the proportion of participants with a Complete Response (CR) or Partial Response (PR) as determined by an IRC- provided radiographic disease assessment of response according to response criteria for lymphomas.
Treatment Emergent Adverse Events 7 Years Adverse events reported for the first time or worsening of a pre-existing event after the first dose of study drug/treatment.
