Diffuse Large B-cell Lymphoma, Nivolumab, Bendamustine Hydrochloride, Gemcitabine, Rituximab
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.
Interventions
70 mg/m2 by intravenous (IV) infusion for up to 2 cycles
500 mg/m2 by intravenous (IV) infusion on day 1,8,15 for up to 2 cycles
700 mg/m2 by intravenous (IV) infusion on day 1,8,15 for up to 2 cycles
1000 mg/m2 by intravenous (IV) infusion on day 1,8,15 for up to 2 cycles
1 mg/kg by intravenous (IV) infusion on day 1,15 for up to 2 cycles
375 mg/m2 by intravenous (IV) infusion on day 0 for up to 2 cycles

Study design
Intervention model description
There will be 2 parts in this study. In Part 1, the safety of combination treatment will be evaluated prior to expansion of enrollment to evaluate treatment effect in Part 2. The arms in Part 1 include 3 different dosage regimens of gemcitabine (500 / 700 / 1000). Part 2 of the study will further characterize the safety and evaluate the antitumor activity of drug combination by enrolling patients at the recommended dose schedule determined in Part 1.
