Glofitamab Combined With Lenalidomide in High Risk Patients With Relapsed or Refractory Mantle Cell Lymphoma

A single-arm, open-label, multi-center clinical study of glofitamab combined with lenalidomide in high risk patients with relapsed or refractory Mantle Cell Lymphoma previously treated with a BTK Inhibitor. Patients will be eligible if they have received one or more prior lines of therapy, one of which must have been a BTKi. Patients will be enrolled according to a Simon two-stage design, with early stop criteria for lack of efficacy. Glofitamab will be administered intravenously and lenalidomide will be self-administered orally. Obinutuzumab pretreatment will be administered intravenously as 2 doses of 1000 mg prior to glofitamab initiation. The primary endpoint is BOR at the end of induction, evaluated by PET/CT according to Lugano criteria during study enrolment. The primary objective is to evaluate the best objective response rate (BOR) at the end of induction of the combination of glofitamab and lenalidomide.
