Study to Evaluate Two Lenalidomide Dose Regimens With Low Dose Dexamethasone for the Treatment Relapsed Multiple Myeloma

Phase 2

Completed

• Conditions: Multiple Myeloma
• Interventions: Drug: Lenalidomide 15mg; Drug: Lenalidomide 25mg

• Registration Number: NCT01380106
• Lead Sponsor: Boston VA Research Institute, Inc.

Brief Summary

This is a research study to evaluate two different Lenalidomide doses (15 mg vs. 25 mg) in combination with low dose dexamethasone in patients with relapsed multiple myeloma.

The investigators propose to use the need for dose reduction as a criterion to judge tolerability from various causes. In the veteran population which predominantly is in the older age category with number of co-morbidities, a lower dose regimen may be safer and advantageous.

This study expects to enroll approximately 80 subjects from participating VA sites across the nation.

The investigators will evaluate the safety of the two dose regimens by comparing frequency of dose reductions. The investigators will also measure how long the responses last with each dose.

Lenalidomide is approved by the Food and Drug Administration (FDA) for the treatment of specific types of myelodysplastic syndrome (MDS) and in combination with dexamethasone for patients with multiple myeloma (MM) who have received at least 1 prior therapy. MDS and MM are cancers of the blood. It is currently being tested in a variety of cancer conditions. In this case it is considered experimental.

At the time of enrollment, one-half of the subjects will be chosen at random to receive the 15 mg Lenalidomide dose and the other half will take the 25 mg dose regimen of Lenalidomide. Depending on lenalidomide treatment assignment, subjects will receive either 15 mg p.o. q.d. or 25 mg p.o. q.d. for days 1-21 of a 28 day cycle. In addition, dexamethasone (40 mg) will be added once a week (Days 1, 8, 15 and 22) to the Lenalidomide regimen, with a dose reduction on the same schedule if the patient cannot tolerate the higher dose of dexamethasone. ASA (81 or 325mg) will be given daily for anticoagulation prophylaxis. Patients intolerant to ASA may use low molecular weight heparin. Lovenox is recommended. Coumadin will be allowed provided the patient is fully anticoagulate with INR 2.0 to 2.5.

Detailed Description

Primary Objective:

• Evaluate the frequency of dose reductions in two different lenalidomide dose regimens.

Secondary Objectives:

* Evaluate the efficacy of two different lenalidomide dose regimens in patients with multiple myeloma using the EBMT and IMWG criteria.

* Evaluate the duration of response of 15 mg Lenalidomide and 25 mg of Lenalidomide when used in combination with Low Dose Dexamethasone.

* Evaluate the safety of 15 mg and 25 mg of Lenalidomide regiments when in combination with dexamethasone.

* Explore blood and cellular levels of angiogenic factors, cytokines, and adhesion molecules.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 33

Inclusion Criteria

1. Previously diagnosed with multiple myeloma.

2. Must have relapsed or refractory disease (refractory is defined as progression during treatment or within 60 days after the completion of treatment) requiring 2nd or 3rd line therapy

3. Patients may have received lenalidomide and/or dexamethasone

4. Patients must have measurable disease:

   • Serum monoclonal protein >0.5g/dL and/or 0.2g/24hr urine light chain excretion
   • Patients with lower M-protein values or non-secretory myeloma will be eligible if measurable disease can be established, such as serum FreeliteTM chain ratio >5x ULN, measurable soft tissue plasmacytoma >2cm by either physical exam and/or applicable radiographs (i.e. MRI, CT-scan) and/or bone marrow involvement >30%

5. Age >=18 years at the time of consent.

6. All necessary baseline studies for determining eligibility must be obtained within 14 days prior to enrollment. Serum pregnancy tests (sensitivity of at least 25 mIU/mL), for females of childbearing potential (WCBP) must be completed. The first test must be performed within 10-14 days, and the second test within 24 hours prior to initiation of lenalidomide.

7. Pre-study ECOG performance status 0-2. Patients with lower performance status based solely on bone pain will be eligible.

8. Adequate liver functions: AST and ALT =< 3xULN, alkaline phosphatase =< 3.0x ULN, except if attributed to tumor, and bilirubin =< 2xULN.

9. Have Amylase =< 2.5x ULN

10. Able to adhere to the study visit schedule and other protocol requirements

11. Must understand and voluntarily sign an informed consent document.

12. Females of childbearing potential (FCBP)† must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL 10 - 14 days prior to and again within 24 hours of starting lenalidomide and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 4 weeks before she starts taking lenalidomide. FCBP must also agree to ongoing pregnancy testing. Men must agree not to father a child and agree to use a condom if his partner is of child bearing potential. All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure.

13. All study participants must be registered into the mandatory RevAssist® program, and be willing and able to comply with the requirements of RevAssist®. All counseling will be done through RevAssist®.
