Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 280
Healthy volunteers: no

Brief summary:
The purpose of this study is to evaluate the efficacy and safety of ibrutinib versus temsirolimus in patients with relapsed or refractory mantle cell lymphoma who received at least 1 prior chemotherapy regimen.

Detailed description:
This is a randomized (individuals assigned to study treatment by chance), open-label (identity of assigned study drug will be known), study to evaluate the efficacy and safety of ibrutinib when compared with temsirolimus in patients with relapsed or refractory mantle cell lymphoma (MCL) who have received at least 1 prior rituximab-containing chemotherapy regimen. Approximately 280 eligible patients will be randomly assigned in a 1:1 ratio and stratified (grouped) by the number of prior lines of therapy (1 or 2 versus \>=3) and simplified MCL International Prognostic Index criteria to receive either ibrutinib by mouth (Treatment Arm A) or temsirolimus intravenous infusion (Treatment Arm B). The study will consist of screening, treatment, and posttreatment phases. Data will be collected on disease response to the treatment, progression-free survival, overall survival, subsequent anti-MCL therapies, patient reported outcomes, and medical resource utilization. Tumor samples, blood collected at multiple time points, and a bone marrow aspirate will be evaluated to identify markers predictive of response or resistance to ibrutinib. Serial pharmacokinetic (study of what the body does to a drug) samples will be collected as detailed in the protocol. Safety will be monitored throughout the study. Disease evaluations will be performed every 9 weeks for up to 15 months from the start of study drug, and every 24 weeks thereafter, until disease progression, death, or the clinical cutoff, whichever comes first. Patients who receive treatment with temsirolimus and have disease progression (confirmed by an Independent Review Committee) may be eligible to crossover and receive treatment with ibrutinib 560 mg orally, daily, on a 21-day cycle until disease progression, unacceptable toxicity, or study end. Data will be analyzed up to 3 years after the last patient is enrolled for the final follow-up.
