Safety and Efficacy of Bendamustine, Gemcitabine, Rituximab, Nivolumab (BeGeRN) in Patients With r/r DLBCL

Registration Number
NCT03259529
Lead Sponsor
St. Petersburg State Pavlov Medical University
Brief Summary

Despite the current advances in clinical oncology, the prognosis of patients with resistant diffuse large B cell lymphoma or relapse after high dose chemotherapy is dismal. Therefore there is a need for the introduction of novel treatment regimens. This phase I/II trial evaluates the safety and efficacy of combination bendamustine, gemcitabine, nivolumab and rituximab in patients with relapsed or refractory diffuse large B-cell lymphoma. The safety of combination treatment will be evaluated with the determination of recommended dose schedule prior to expansion of enrollment to evaluate the antitumor activity of bendamustine, gemcitabine, rituximab, and nivolumab.
