Study type | Interventional |
In this phase II multicenter trial we plan to use acalabrutinib before and after allogeneic hematopoietic stem cell transplantation (alloSCT) with reduced intensity conditioning (RIC) in patients with refractory/relapsed MCL and CLL with poor prognostic factors. Acalabrutinib will be used before alloSCT with the intention to reduce tumor burden and after transplant to augment disease control.
