Study of Ibrutinib (a Bruton's Tyrosine Kinase Inhibitor), Versus Temsirolimus in Patients With Relapsed or Refractory Mantle Cell Lymphoma Who Have Received at Least One Prior Therapy
- Registration Number
- NCT01646021
- Lead Sponsor
- Janssen Research & Development, LLC
- 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.

- Primary Outcome Measures
Name Time Method Progression Free Survival (PFS) Time from the date of randomization until the date of first documented evidence of progressive disease (or relapse for subjects who experience CR during the study) or death, whichever occurred first (approximately 48 months) PFS is defined as the duration in months from the date of randomization to the date of progression disease (PD) or relapse from complete response (CR) or death whichever was reported first and was assessed based on the investigator assessment. Revised Response Criteria for Malignant Lymphoma categorizes the response of the treatment of a patient's tumour to CR (the disappearance of all evidence of disease), Relapsed Disease or PD (Any new lesion or increase by greater than or equal to \[\>=\] 50 percent \[%\] of previously involved sites from nadir).
- Secondary Outcome Measures
Name Time Method Progression-Free Survival 2 Approximately up to 48 months Progression-free survival 2 defined as the time interval between the date of randomization and date of event, defined as progressive disease as assessed by investigator that started after the next line of subsequent anti-neoplastic therapy (including cross-over to ibrutinib), death from any cause, or the start of the second subsequent anti-neoplastic therapy if no progressive disease was recorded after the first subsequent anti-neoplastic therapy.
Time to Worsening in the Lymphoma Sub Scale of Functional Assessment of Cancer Therapy- Lymphoma (FACT-Lym) Approximately up to 48 months Time to worsening in the Lymphoma subscale of the FACT-Lym, defined as the interval from the date of randomization to the start date of worsening. Worsening was defined by a 5-point decrease from baseline. FACT-Lym Lymphoma subscale contains 15 questions, scores from 0 to 4 for each question (higher the worse). Lymphoma subscale score is the total of reverse scores, range 0 to 60. Higher scores indicate a better quality of life.
Overall Response Rate (ORR) Approximately up to 48 months ORR is defined as the percentage of participants who achieved either CR or PR as best overall response based on the investigator assessment. CR is Disappearance of all target lesions while PR is greater than or equal to 30 % decrease in the sum of the longest diameter of target lesions and Overall Response (OR) is sum of CR and PR.
Overall Survival (OS) Approximately up to 48 months Overall survival (OS) was defined as the interval between the date of randomization and the date of death from any cause.
Duration of Response Approximately up to 48 months Duration of response (CR or PR), defined as the duration in days from the date of initial response to the date of first documented evidence of progressive disease (or relapse for participants who experience CR during the study) or death. The analysis was based on the investigator assessment.
Time-to-Next Treatment Approximately up to 48 months Time to next treatment was measured from the date of randomization to the start date of any anti-neoplastic treatment subsequent to study treatment.
Number of Participants Affected With Treatment-emergent Adverse Events Time from first dose of study drug until the last dose date + 30 days or the start of a subsequent anti-neoplastic therapy, whichever occur earlier (Approximately up to 4 years) An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
