Carfilzomib, Bendamustine Hydrochloride, and Rituximab in Treating Patients with Relapsed or Refractory B-cell Non-Hodgkin Lymphoma
This phase Ib trial studies the side effects and best dose of carfilzomib when given together with bendamustine hydrochloride and rituximab in treating patients with B-cell non-Hodgkin lymphoma that has returned after a period of improvement or has not responded to previous treatment. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Giving carfilzomib together with bendamustine hydrochloride and rituximab may be a better treatment for B-cell non-Hodgkin lymphoma.

Trial Objectives and Outline
I. To assess the safety and tolerability of carfilzomib when combined with bendamustine (bendamustine hydrochloride) and rituximab in patients with relapsed or refractory non-Hodgkin’s lymphoma.
I. To evaluate the preliminary antitumor activity of carfilzomib with bendamustine and rituximab in patients with non-Hodgkin lymphoma (dose escalation) and with specific non-Hodgkin lymphoma (NHL) subtypes (dose expansion).
I. To describe overall survival in patients treated with these agents.
II. To evaluate the relationship between antitumor activity or toxicity of carfilzomib and bendamustine with markers of activation of the terminal unfolded protein response (UPR) and/or modulation of the apoptotic pathway in primary tumor tissue.
OUTLINE: This is a dose-escalation study of carfilzomib.
Patients receive carfilzomib intravenously (IV) over 30 minutes twice weekly on days 1, 2, 8, 9, 15, and 16 or weekly on days 2, 9, and 16; bendamustine hydrochloride IV over 60 minutes on days 1 and 2; and rituximab IV over 30-90 minutes on day 9 (course 1 only) and day 1 (subsequent courses). Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 6 weeks for 6 months, every 3 months for 6 months, and then every 6 months thereafter.
