ClinicalTrials.gov Identifier:	NCT00006219

Purpose

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. Dehydroepiandrosterone and clarithromycin may be effective in preventing multiple myeloma.

PURPOSE: Randomized phase II trial to compare the effectiveness of dehydroepiandrosterone with that of clarithromycin in treating patients who may be at a high risk of developing multiple myeloma.

Detailed Description:

OBJECTIVES:

Determine whether dehydroepiandrosterone (DHEA) or clarithromycin causes a significant reduction in bone marrow plasmacytosis, serum and/or urine M protein or Bence Jones protein, and surrogate endpoint biomarkers in patients with monoclonal gammopathy of undetermined or borderline significance.
Determine whether differences in interleukin-1-beta (IL-1-beta) expression and IL-1-beta dependent biomarkers (adhesion molecule expression and serum interleukin-6 levels) are useful surrogate endpoint biomarkers in these patients.
Determine whether differences in ploidy, proliferative index, nuclear pleomorphism index, circulating monoclonal plasma cells, Th1/Th2 ratios, serum s-interleukin-6R (SIL-6R) levels, interleukin-6 and SIL-6R expression, or plasma cell apoptosis assay are useful surrogate endpoint biomarkers in these patients.
Determine the effects of these treatment regimens on the quality of life of these patients.

OUTLINE: This is a randomized, double-blind, placebo-controlled study. Patients are stratified according to disease (monoclonal gammopathy of undetermined significance vs monoclonal gammopathy of borderline significance) and monoclonal protein abnormality (IgG vs IgA). Patients are randomized to 1 of 4 treatment arms.

Arm I: Patients receive oral dehydroepiandrosterone (DHEA) once daily.
Arm II: Patients receive oral clarithromycin once or twice daily.
Arm III: Patients receive oral placebo once daily.
Arm IV: Patients receive oral placebo twice daily. Treatment continues for 6 months in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline, 6 months, 12 months, and then at disease progression.

Patients are followed every 3 months for 1 year and then every 6 months for 1.5 years.

PROJECTED ACCRUAL: A total of 75 patients (25 per treatment arms I and II and 25 between arms III and IV) will be accrued for this study within 2.5 years.
