CC-5013 Plus Dexamethasone Versus Dexamethasone Alone in Previously Treated Subjects With Multiple Myeloma

Randomized subjects will receive CC-5013 plus high-dose dexamethasone or placebo appearing identical to CC-5013 plus high-dose dexamethasone in 4-week cycles. Each subject will participate in a treatment phase and a follow-up phase.

About this study

This was a phase 3, multicenter, double-blind, placebo-controlled, parallel-group study of the efficacy and safety of CC-5013 plus oral pulse high-dose dexamethasone and oral pulse high-dose dexamethasone therapy alone in subjects with relapsed or refractory multiple myeloma. Eligible subjects were randomized in a 1:1 ratio to 1 of 2 treatment groups: Subjects in the CC-5013/Dex treatment group took 25 mg of CC-5013 orally once daily on Days 1 to 21 and a matching placebo capsule once daily on Days 22 to 28 of each 28-day cycle; Subjects in the Placebo/Dex treatment group took 1 placebo capsule on Days 1 to 28 of each 28-day cycle. Subjects in both treatment groups took 40 mg of dexamethasone orally once daily on Days 1 to 4, 9 to 12, and 17 to 20 of each 28-day cycle for the first 4 cycles of therapy. Beginning with Cycle 5, the dose of dexamethasone was reduced to 40 mg orally once daily on Days 1 to 4 for the remaining cycles.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Prior or current diagnosis Durie-Salmon stage II or III multiple myeloma.
  • No more than 3 previous anti-myeloma regimens
  • No high-dose dexamethasone (total monthly dose of dexamethasone greater than 200 mg) within 6 months of study randomization.
  • Measurable levels of myeloma paraprotein in serum or urine (24-hour collection sample).

Exclusion criteria

  • Prior development of disease progression during high-dose dexamethasone containing therapy.
  • Laboratory abnormalities: Absolute neutrophil count less than 1,000 cells/mm cubed
  • Laboratory abnormalities: Platelet count less than 75,000/mm cubed
  • Laboratory abnormalities: Serum creatinine greater than 2.5 mg/dL
  • Laboratory abnormalities: Serum glutamic oxaloacetic transaminase (SGOT, aspartate transaminase [AST]) or serum glutamic pyruvic transaminase (SGPT, alanine transaminase [ALT])greater than 3.0 x upper limit of normal
  • Laboratory abnormalities: Serum total bilirubin greater than 2.0 mg/dL
  • Prior history of malignancies other than multiple myeloma unless the subject has been free of the disease for greater than or equal to 5 years.
  • Known hypersensitivity to thalidomide or dexamethasone.
  • Development of a desquamating rash while taking thalidomide.

Treatment and study plan

CC-5013

Drug

Subjects in the CC-5013/Dex treatment group took 25 mg of lenalidomide orally once daily on Days 1 to 21 and a matching placebo capsule once daily on Days 22 to 28 of each 28-day cycle.

Other names: lenalidomide, Revlimid

Dexamethasone

Drug

Subjects in the CC-5013/Dex and Placebo/Dex treatment groups took 40 mg of dexamethasone orally once daily on Days 1 to 4, 9 to 12, and 17 to 20 of each 28-day cycle for the first 4 cycles of therapy. Beginning with Cycle 5, the dose of dexamethasone was reduced to 40 mg orally once daily on Days 1 to 4 for the remaining cycles.

Other names: Decadron

Primary outcomes

  1. Time to Tumor Progression (TTP)

    Time frame: 60 weeks (median Time To Progression of CC-5013/Dex treatment group)

    Time to progression (TTP) was calculated as the time from randomization to the first documentation of progressive disease based on the myeloma response determination criteria developed by Bladé et. al., Br J Haematol 1998; 102:1115-1123.

Secondary outcomes

  1. Overall Survival

    Time frame: 170 weeks (median overall survival of CC-5013/Dex treatment group)

    Overall survival was calculated as the time from randomization to death from any cause.

  2. Myeloma Response

    Time frame: Up to Unblinding (07 Jun 2005)

    The overall confirmed response that was maintained for ≥6 weeks. Complete Response (CR):Disappearance of monoclonal paraprotein. Remission Response (RR):75-99% reduction in monoclonal paraprotein/90-99% reduction in 24-hr urinary light chain excretion. Partial Response (PR):50-74% reduction in monoclonal paraprotein/50-89% reduction in 24-hr urinary light chain excretion. Stable Disease (SD):Criteria for PR or PD not met. Plateau Phase:If PR, stable monoclonal paraprotein (within 25% above or below nadir)/stable soft tissue plasmacytomas. Progressive Disease (PD):Disease worsens.

  3. Time to First Worsening of Eastern Cooperative Oncology Group (ECOG) Performance Status Scale (Best Score=0, Fully Active, Able to Carry on All Pre-disease Performance Without Restriction; Worst Score=5, Dead.)

    Time frame: 30 weeks (mean time to first worsening of ECOG performance status for CC-5013/Dex treatment group)

    The time to first worsening on the ECOG Performance Scale was calculated as the time from randomization to the date of the first worsening compared to the last ECOG evaluation obtained prior to randomization.
