简要总结
This is a Phase 3 study to investigate the safety and efficacy of the investigational drug, zilovertamab, when given in combination with ibrutinib in patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL).
详细描述
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study that will be conducted in multiple phases in patients with R/R MCL. The study phases will include a Screening Phase, an Open-Label Ibrutinib Monotherapy Treatment Phase, a Randomized Double-Blind Treatment Phase, and a Long-Term Follow-Up Phase. When patients meet all study eligibility requirements in the Screening Phase, they will enter the Open-Label Ibrutinib Monotherapy Treatment Phase and will receive ibrutinib alone daily. After approximately 16 weeks patients who have a partial response (PR) or stable disease (SD) will enter the Randomized Double-Blind Treatment Phase and will be receive an intravenous infusion of zilovertamab or placebo and will continue to receive ibrutinib daily. Patients who discontinue study drug will enter the Long-Term Follow-Up Phase.
