A Study to Compare MPR With MP in Newly Diagnosed Multiple Myeloma Subjects 65 Years Old or Older.

Newly Diagnosed Multiple Myeloma Clinical Trial

Official title: A PHASE III, MULTICENTRE, RANDOMISED, DOUBLE-BLIND, PLACEBO-CONTROLLED, 3-ARM PARALLEL GROUP STUDY TO DETERMINE THE EFFICACY AND SAFETY OF LENALIDOMIDE (REVLIMID¿) IN COMBINATION WITH MELPHALAN AND PREDNISONE VERSUS PLACEBO PLUS MELPHALAN AND PREDNISONE IN SUBJECTS WITH NEWLY DIAGNOSED MULTIPLE MYELOMA WHO ARE 65 YEARS OF AGE OR OLDER

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to determine whether lenalidomide is safe and effective in the treatment of patients with newly diagnosed Multiple Myeloma who are 65 years of age or older.

Clinical Trial Description

The three phases for the study as originally defined and as represented in the results of 11 May 2010 are:

Double-blind Treatment Phase: Induction Melphalan/prednisone and lenalidomide 10 mg (MPR) (2 treatment arms), or melphalan/prednisone and placebo (MPp) (1 treatment arm) for up to 9 cycles. If disease progression, subjects have the option to enter into the Open-Label Extension Phase. There is also an option to enter into the Follow-Up Phase. If the disease has not progressed, subject can continue blinded therapy into Maintenance.

Double-blind Treatment Phase: Maintenance One MPR treatment arm (MPR+R) will continue taking lenalidomide 10 mg in Maintenance. The other MPR treatment arm (MPR+p) will take placebo in Maintenance. The MPp treatment arm will take placebo in Maintenance (MPp+p). If disease progression, subjects have the option to enter the Open-Label Extension Phase to obtain treatment with lenalidomide, or to enter into the Follow-up Phase.

Open-label Extension Phase:

Treatment consists of oral lenalidomide (up to 25 mg) with or without dexamethasone until disease progression or treatment is discontinued for any reason until all study subjects are followed for at least 5 years from the date of randomization or have died. Subjects who discontinue from the Open-Label Extension Phase prior to completing a total of 5 years in the study will enter the Follow-up Phase.

Follow-up Phase:

Subjects are followed for overall survival and subsequent anti-myeloma treatment regimens until all subjects in this study are followed for at least 5 years from randomization or have died.

The pre-planned interim analysis for the Independent Data Monitoring Committee (IDMC) showed that the difference in progression-free survival (PFS) between treatment arms MPR+R and MPp+p (the defined primary comparative analysis for this study) surpassed the pre-specified O'Brien-Fleming boundary for superiority. The IDMC recommended the release of this information to the sponsor and also recommended that all patient and physician study participants receive information concerning the full findings of the MM-015 interim analysis. Therefore, due to these recommendations from the IDMC, treatment-arm codes were sent to the clinical trial centers to unblind the treatment arms of their study subjects once the amended protocol was reviewed and approved by the respective country Health Authorities and Ethics Committees. Subject participation in the MM-015 study continued after unblinding to obtain long-term data for all study endpoints, including overall survival.

When the study was unblinded, subjects still on protocol therapy had completed the Double-Blind Induction, and were on monotherapy in Double-Blind Maintenance. Subjects in arm MPR+R continued their monotherapy on lenalidomide. Subjects in arms MPR+p and MPp+p discontinued their placebo monotherapy and went into an observation period in which no antimyeloma therapy was taken. If disease progressed for any subject, the investigator had the option of entering the subject in Open Label Extension Phase to receive lenalidomide therapy (up to 25 mg daily) or the Follow-up Phase. All subjects were to be followed for at least 5 years from the start of the study. ;
