Bruton's Tyrosine Kinase (BTK) Inhibition in B-cell Lymphomas

The primary objective of this study is to determine the recommended dose of ibrutinib when administered in combination with R-DHAP (rituximab + dexamethasone + cytarabine + cisplatin) or with R-DHAOx (rituximab + dexamethasone + cytarabine + oxaliplatin) in patients with relapsed or refractory B-cell malignancies eligible for autologous stem cell transplantation (ASCT) by assessing the maximum tolerated dose (MTD) observed during the dose escalation part of the study. Assessment of the MTD will be performed by the analysis of the dose-limiting toxicities (DLTs).
