About this study

Official title: The Clinical and Biologic Evaluation of Polyphenon E, an Extract of Green Tea Containing EGCG, in Plasma Cell Dyscrasias - Pilot Study

RATIONALE: Green tea extract contains ingredients that may prevent or slow the growth of monoclonal gammopathy of undetermined significance and/or smoldering multiple myeloma.

PURPOSE: This phase II trial is studying how well green tea extract works in treating patients with monoclonal gammopathy of undetermined significance and/or smoldering multiple myeloma.

Read the detailed description

OBJECTIVES:

Primary

  • Conduct a pilot study investigating the effects of Polyphenon E, a compound extracted from green tea which contains epigallocatechin-3-gallate (EGCG), on monoclonal protein levels in patients with monoclonal gammopathy of undetermined significance and/or smoldering multiple myeloma.

Secondary

  • Collect, process, and store blood and marrow specimens for future measurement of the biologic effects of Polyphenon E on the plasma cells of these patients by utilizing proteosome activity assays and gene expression profiling.

OUTLINE: Patients receive oral green tea catechin extract (Polyphenon E) daily on days 1-28. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Patients may undergo blood, urine, and bone marrow sample collection periodically for correlative laboratory studies. Samples are analyzed for monoclonal protein (M-protein) levels, proteosome function, and gene expression.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sustained M-protein Reduction of ≥ 25% From Baseline

    This is a monthly blood test, done at the beginning of each cycle of therapy. The M-protein is a surrogate marker routinely used to estimate the degree of plasma cell cyto-reduction brought about by therapy. In active multiple myeloma, a 25% reduction in the M-protein level would correspond to a "minor response," an improvement recognized as having some clinical benefit.

    Measured: Day one of each 28-day cycle for a total of up to 6 cycles

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing defined green tea catechin extract, gene expression analysis and protein analysis in people with Multiple Myeloma and Plasma Cell Neoplasm and Precancerous Condition, run by Barbara Ann Karmanos Cancer Institute at 1 site 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?

The sponsor lists 14 inclusion and 13 exclusion criteria. 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: stopped early, as of the sponsor's last update on 27 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

Yes. Results are posted in the registry (first posted 27 Mar 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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.

What does the primary outcome measure?

Sustained M-protein Reduction of ≥ 25% From Baseline (time frame: Day one of each 28-day cycle for a total of up to 6 cycles). It is what the study was designed to measure, not a finding.

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 27 Mar 2015.
