Trial Description

Summary

This randomized phase III trial is studying lenalidomide and low-dose dexamethasone to see how well it works compared to lenalidomide and standard-dose dexamethasone in treating patients with multiple myeloma. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Lenalidomide and thalidomide may also stop the growth of multiple myeloma by blocking blood flow to the cancer. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving lenalidomide, thalidomide, and dexamethasone together may kill more cancer cells.

Further Study Information

PRIMARY OBJECTIVES:

I. To evaluate the response rate and toxicity of CC-5013 (lenalidomide) plus dexamethasone (standard dose) versus CC-5013 plus low dose dexamethasone in patients with newly diagnosed myeloma at any time in the first 4 cycles of treatment and to determine if CC-5013 plus low dose dexamethasone will have similar response rate with lower toxicity (First Phase).

SECONDARY OBJECTIVES:

I. To evaluate the response rate of thalidomide plus dexamethasone (Thal/Dex) in patients with newly diagnosed myeloma who do not achieve a complete or partial response at any time in the first 4 cycles with the CC-5013 and dexamethasone combination in either of the two arms (First Phase).

II. To study the effect of CC-5013 on bone marrow microvessel density and angiogenesis grade, on plasma cell labeling index (PCLI), and on the expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in the marrow (First Phase).

III. To study the effect of CC-5013 and dexamethasone on bone marrow mesenchymal progenitor cells (MPCs) (First Phase).

IV. To evaluate in a separate expansion phase the efficacy of aspirin (325 mg/day) versus Coumadin (dose adjusted to maintain a target international normalized ratio (INR) of 2-3) in preventing deep vein thrombosis (DVT) in patients with newly diagnosed myeloma receiving CC-5013 plus standard dose dexamethasone. This separate expansion phase of the trial that will start after accrual to the first phase of the trial testing the primary objective listed above is completed.

OUTLINE: This was an open label, randomized phase III study of CC-5013 (lenalidomide, Revlimid ®) plus high-dose dexamethasone versus lenalidomide plus low-dose dexamethasone in newly diagnosed multiple myeloma patients. Beginning when accrual for the primary objective was completed, a substudy comparing two anticoagulation regimens each given with high-dose dexamethasone opened. Hereafter, the original design is referred to as the 'First Phase' and the substudy, the 'Expansion Phase'. The purpose of the expansion phase is to determine if anticoagulation with coumadin to a target INR of 2-3 will be significantly superior to aspirin 325 mg/day in preventing DVTs (and related thromboembolic events) in patients with newly diagnosed myeloma.

The expansion phase opened in January 2007. After the first pre-planned interim analysis, evidence of an overall survival advantage on the low dose arm prompted early release of survival data, and the DMC recommended that the expansion phase close and required all patients switch to the low-dose dexamethasone regimen. As the expansion phase was terminated early with only 7 patients enrolled, the clinical results presented are mainly for the first phase only. Toxicity data are available for both the first phase and the expansion phase.

Patients were randomized to 1 of 2 treatment arms in the first phase.

First Phase:

Arm I: Patients receive oral lenalidomide once daily on days 1-21, oral aspirin (or other deep vein thrombosis prophylaxis at the discretion of the principal investigator) once daily on days 1-28, and standard-dose oral dexamethasone once daily on days 1-4, 9-12, and 17-20. Patients with minimal response or no response after 4 cycles of treatment could register for Step 2 treatment with thalidomide and high-dose dexamethasone. Thalidomide was given orally once daily on days 1-28, and dexamethasone once daily on days 1-4, 9-12, and 17-20 for 4 cycles.

Arm II: Patients receive oral lenalidomide and acetylsalicylic acid as in arm I and low-dose oral dexamethasone once daily on days 1, 8, 15, and 22. Patients with minimal response or no response after 4 cycles of treatment could register for Step 2 treatment with thalidomide and low-dose dexamethasone. Thalidomide was given orally once daily on days 1-28, and dexamethasone once daily on days 1, 8, 15, and 22 for 4 cycles.

Expansion Phase: Patients registered after Addendum #6 were randomized to either Arm III or Arm IV.

Arm III: Patients receive oral lenalidomide once daily on days 1-21, oral aspirin (or other deep vein thrombosis prophylaxis at the discretion of the principal investigator) once daily on days 1-28, and standard-dose oral dexamethasone once daily on days 1-4, 9-12, and 17-20. After 4 cycles of treatment, patients may discontinue treatment or continue until progression.

Arm IV: Patients receive oral lenalidomide once daily on days 1-21, oral aspirin (or other deep vein thrombosis prophylaxis at the discretion of the principal investigator) once daily on days 1-28, and standard-dose oral dexamethasone once daily on days 1-4, 9-12, and 17-20. After 4 cycles of treatment, patients may discontinue treatment. For patients continuing therapy beyond 4 cycles, coumadin was discontinued and aspirin was given instead.

Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually for 2 years.
