Celecoxib in Preventing Multiple Myeloma in Patients With Monoclonal Gammopathy or Smoldering Myeloma

This study has been completed.

This randomized phase II trial studies how well celecoxib works in preventing multiple myeloma in patients with monoclonal gammopathy or smoldering myeloma. Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of celecoxib may be effective in preventing multiple myeloma.

Primary Outcome Measures:
  • Changes in M-protein Levels [ Time Frame: Baseline and 6 months ]
    For a given biomarker (or a suitable transformation of it, e.g. log transform) t-tests and Wilcoxon tests (2-sample t-test and Wilcoxon rank sum test for between treatment comparisons, and paired 1-sample t-test and Wilcoxon signed rank test for within treatment comparisons) will be used to detect statistically significant differences between (or within) treatments.

Enrollment: 23
Study Start Date: November 2004
Study Completion Date: November 2008
Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I (celecoxib)

Drug: celecoxib
Given PO
Other Name: Celebrex
Other: laboratory biomarker analysis
Correlative studies
Placebo Comparator: Arm II (placebo)
Patients receive placebo PO BID for 6 months in the absence of unacceptable toxicity or progression to malignancy.
Drug: placebo
Given PO
Other: laboratory biomarker analysis
Correlative studies

Detailed Description:


I. Determine the efficacy of celecoxib vs placebo in reducing serum levels of M-component in patients with monoclonal gammopathy of undetermined significance or smoldering myeloma.


I. Determine the effects of this drug on secondary biomarkers as surrogate endpoints in these patients.


This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to participating center and type of monoclonal gammopathy (monoclonal gammopathy of undetermined significance vs smoldering myeloma). Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive celecoxib orally (PO) twice daily (BID) for 6 months in the absence of unacceptable toxicity or progression to malignancy.

ARM II: Patients receive placebo PO BID for 6 months in the absence of unacceptable toxicity or progression to malignancy.

After completion of study treatment, patients are followed at 1, 6, and 12 months.
