About this study
Official title: A Phase II Clinical Trial of Dehydroepiandrosterone and Biaxin in Monoclonal Gammopathy of Undetermined and Borderline Significance
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.
Read the 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.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing clarithromycin and prasterone in people with Multiple Myeloma and Plasma Cell Neoplasm, run by Mayo Clinic at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2011; AzTrials last refreshed its copy on 7 Nov 2026.
