Brief Summary:

Patients with myeloma that has either not responded to previous treatment or has returned after previous treatment will be given a combination of the drugs bendamustine and bortezomib.

The bortezomib and bendamustine will be given using an intravenous line (IV) on days 1 and 4 of each cycle, with bortezomib being given first, before each dose of bendamustine. Each cycle will be 28 days long, so patients will be treated the first week of each cycle and then have 3 weeks 'off' (without any treatment). Disease assessments will be performed on day 22 of each cycle. Patients will receive the study drugs until their disease progresses or they are withdrawn from the study.

In other studies, bendamustine seems to work well with other drugs. Thus, this study hopes to show that the combination of bortezomib and bendamustine will have activity in relapsed/refractory myeloma.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: Bendamustine Drug: Bortezomib Phase 2

Detailed Description:

Patients with relapsed and refractory myeloma who have a measurable paraprotein in the serum or urine or measurable protein by Freelite or measurable disease by plasmacytoma will be given a combination of bendamustine and bortezomib each cycle. Response rate (PR or better after 2 cycles) and duration of response will be assessed. Therapy will be continued until disease progression. The bendamustine would be used in a day 1, day 4 dosing schedule after each dose of bortezomib to take advantage of the chemosensitizing properties of bortezomib. This minimizes the days of treatment to just the first week and allows rebound of blood counts. This will be a phase II trial with dose reduction as necessary.

Bendamustine is a drug which appears to be non-cross-resistant with other alkylating agents in vitro and in vivo. Thus, we hypothesize that the combination of bortezomib and bendamustine will have activity in relapsed/refractory myeloma.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 24 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Trial of Bortezomib and Bendamustine in the Treatment of Relapsed/Refractory Myeloma
Study Start Date : September 2011
Actual Primary Completion Date : February 2014
Actual Study Completion Date : September 2015

Arm Intervention/treatment
Experimental: Bortezomib and Bendamustine Drug: Bendamustine

On days 1 and 4 of each cycle, bendamustine is given at 90 mg/m^2 after bortezomib . Patients will be dose reduced to 75 mg/m^2, and then to 60 mg/m^2 bendamustine on days 1 and 4 if ANC is not >1 x 10^9/L and platelets are not >50 x 10^9/L on day 1 of each cycle.

Patients will be treated until disease progression after at least one cycle of treatment.

Other Names:
  • Bendamustine HCl
  • Treanda

Drug: Bortezomib

On days 1 and 4 of each cycle, bortezomib is given first at 1.3 mg/m^2 followed by bendamustine given at 90 mg/m^2. Patients will be dose reduced to 75 mg/m^2, and then to 60 mg/m^2 bendamustine on days 1 and 4 if ANC is not >1 x 10^9/L and platelets are not >50 x 10^9/L on day 1 of each cycle.

Patients will be treated until disease progression after at least one cycle of treatment.

Other Name: Velcade

Primary Outcome Measures :
  1. Percent Change Response Rate (Partial Response or Better After 2 Cycles) Following Treatment With Bortezomib and Bendamustine [ Time Frame: 8 weeks ]
    These criteria included measures of alteration in the natural history of disease, hematologic improvement, cytogenetic response, and improvement in health-related quality of life.The IWG criteria define 4 aspects of responses based on treatment goals: (1) altering the natural history of the disease, (2) cytogenetic response, (3) hematologic improvement (HI), and (4)Quality of Life (QOL)

Secondary Outcome Measures :
  1. Toxicity of This Regimen. [ Time Frame: Every 4 weeks. ]
    Study toxicity will be measured on an ongoing basis, no less then once per 28-day cycle.

  2. Duration of Response of This Regimen. [ Time Frame: from initial response to relapse, up to 100 weeks. ]
    Time from response to relapse. Response would have been assessed using European Group for Blood and Marrow Transplantation (EBMT) criteria modified to include near complete remission (nCR) and very good partial remission (VGPR
