About this study

Official title: Pase II Study of Glucosamine With Chondroitin on Joint Symptoms Induced By Aromatase Inhibitors in Breast Cancer Patients

Investigators are hoping to learn if glucosamine with chondroitin can help relieve joint pain/stiffness associated with aromatase inhibitors.

Read the detailed description

Due to early detection and improved treatments, women with breast cancer are living longer. The increase in breast cancer survival is largely due to the benefits of hormonal therapy, such as tamoxifen and aromatase inhibitors (AIs), for the treatment of hormone-sensitive breast cancer. Recent clinical trials have demonstrated that AIs are more effective than tamoxifen at reducing breast cancer recurrences. However, breast cancer patients receiving AIs have a higher incidence of osteoporosis, bone fractures and musculoskeletal symptoms, particularly joint pain and stiffness. Musculoskeletal pain, which occurs in up to 50% of patients treated with AIs, often does not respond to conventional pain medications, may lead to noncompliance, may cause major disability, and may interfere with quality of life. Many women are unable to tolerate these life-saving drugs because of severe joint pain, therefore, safe and effective treatments that alleviate these symptoms are needed.

What is being measured

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

  1. Change in WOMAC Score

    This is to demonstrate improvement in knee and/or joint pain and/or stiffness. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Hip and Knee Osteoarthritis. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales. The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The sum of the scores for all three subscales gives a total WOMAC score which ranges from 0-96. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.

    Measured: Baseline and 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Chondroitin and Glucosamine in people with Breast Cancer and Joint Pain, run by Dawn L. Hershman 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 11 inclusion and 23 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: finished, as of the sponsor's last update on 8 Nov 2022. 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 8 Nov 2022). 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?

Change in WOMAC Score (time frame: Baseline and 24 weeks). 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 8 Nov 2022; AzTrials last refreshed its copy on 8 Nov 2026.
