Brief Summary:
The study is being done to see if the combination of bendamustine and dexamethasone will help people with amyloidosis that has returned after standard treatment, and to to estimate the partial hematologic response rate (PHR).

Condition or disease Intervention/treatment Phase
AL Amyloidosis Drug: Bendamustine Drug: Dexamethasone Phase 2

Detailed Description:

Systemic light-chain amyloidosis (AL) is a protein conformation disorder due to a clonal plasma cell dyscrasia. There are no established and approved second-line therapies for patients with systemic AL amyloidosis who fail initial melphalan-based treatment, be it high-dose melphalan with stem cell transplant or oral melphalan and dexamethasone (MDex). Therefore new treatments are needed for those who fail initial therapy and for those who initially respond but subsequently relapse.

Therapy of AL is generally based on treatment regimens used in multiple myeloma (MM). Bendamustine achieves partial response with relapsed/refractory MM. Based on this high anti-MM activity, we anticipate that bendamustine will also be very active in clonal plasma cell disorder associated with AL.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 40 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Study of the Combination of Bendamustine and Dexamethasone in Patients With Relapsed AL Amyloidosis
Actual Study Start Date : June 2012
Actual Primary Completion Date : March 2019
Actual Study Completion Date : July 3, 2019

Arm Intervention/treatment
Experimental: Treatment Arm
Subjects with AL will receive Bendamustine and Dexamethasone
Drug: Bendamustine

Patients will start bendamustine at dose level 0 and according to CrCl on day 1 and 2 of each cycle:

  • CrCl ≥ 60 mL/min: 100 mg/m2 IV on day 1 and 2 of each cycle
  • CrCl 59 - 30 mL/min: 90 mg/m2 IV on day 1 and 2 of each cycle

Available to qualifying subjects is the option to dose escalate to dose level (+)1:

  • 120 mg/m2 (if CrCl ≥ 60 mL/min at the time of inclusion into the study)
  • 100 mg/m2 (if CrCl 59-30 mL/min at the time of inclusion into the study)
Other Names:
  • Bendamustine Hydrochloride
  • Treanda ®

Drug: Dexamethasone
40 mg orally on days 1, 8, 15, 22 of each cycle
Other Name: Decadron

Primary Outcome Measures :
  1. Partial hematologic response rate [ Time Frame: Up to 2 years ]
    Only patients who have received at least 2 cycles of therapy are eligible for response assessment. The proportion of patients with PHR two months post-treatment will be estimated, with a 95% exact binomial confidence interval.

Secondary Outcome Measures :
  1. Overall hematologic response rate (OHR) [ Time Frame: Up to 2 years ]
    The proportion of response-evaluable patients experiencing OHR will be estimated, with a 95% exact binomial confidence interval.

  2. Organ response rate (ORR) [ Time Frame: Up to 2 years ]
    The proportion of response-evaluable patients experiencing ORR will be estimated, with a 95% exact binomial confidence interval.

  3. Time to Treatment Failure (TTF) [ Time Frame: Up to 2 years ]
    Time to failure will be assessed for each patient from day of first treatment, where failure will be defined as disease progression or death. The survival function of TTF for response-evaluable patients will be estimated using the product-limit (Kaplan-Meier) estimator, along with 95% confidence bounds. The median time to failure will be estimated from the survival function. The analysis will be repeated on all patients who receive any therapy.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female patients aged ≥ 18 years old

  • Demonstrate measurable disease as defined by one or more of the following:

    • Serum monoclonal protein ≥ 0.5 g/dL by serum electrophoresis
    • Urine monoclonal protein > 200 mg/dL in a 24 hr urine electrophoresis
    • Serum immunoglobulin free light chain ≥ 5 mg/dL and abnormal serum immunoglobulin kappa lambda free light chain ratio. The difference between involved and uninvolved free light chains should be ≥ 5 mg/dL (dFLC)

  • Patients had at least one prior regimen consisting of at least 1 cycle
  • If not previously transplanted, patient should be either ineligible for autologous stem cell transplantation (ASCT), or must have declined the option of ASCT. Patients who have previously had ASCT and have subsequently progressed are eligible, provided other entry criteria are met
  • Ability to provide written informed consent obtained prior to participation in the study and any related procedures being performed

Patients must meet the following laboratory criteria:

  • Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L
  • Hemoglobin ≥ 9 g/dl (May transfuse packed red blood cells (PRBC) to meet parameter)
