RecruitingPhase 2Drug trialPhase II Study of Glofitamab With Venetoclax +/- Zanubrutinib in High-risk Mantle-cell LymphomaThis open-label, multicenter, three cohorts, phase II study is designed to assess a combination of Zanubrutinib/Venetoclax/Glofitamab or Venetoclax/Glofitamab in high-risk subjects with either first line or R/R Mantle Cell Lymphoma (MCL). Three independent cohorts will be run: * Cohort A will include subjects with a primary refractory or progressive disease within 24 months from initiation of first line treatment (POD 24). * Cohort B will be open for subjects with R/R MCL and refractory or progressive to a BTK inhibitor given previously (\>24 months if first line). * Cohort C will only enrol newly diagnosed and untreated MCL subjects with very high-risk features.
