Glucosamine and Chondroitin in Gut in Preventing People From Inflammation
A Phase 1 study testing Glucosamine Sulfate/Chondroitin Sulfate Tablet in people with Healthy Subject, run by Fred Hutchinson Cancer Center at 1 site in United States.
Trial summary
This trial studies glucosamine and chondroitin in preventing inflammation. Glucosamine and chondroitin often used as a dietary supplement to promote joint health may have a preventive role in inflammation and cancer. This trial may help identify the bacteria that help process them in the gut. Read more about this study

PlaceboOther
Also called PLCB, sham therapy
Given PO
| Study group | Role | What they receive |
|---|---|---|
| Arm I (glucosamine sulfate/chondroitin sulfate tablet) | Experimental | Patients receive glucosamine sulfate/chondroitin sulfate tablet PO on days 1-14 in the absence of disease progression or unacceptable toxicity. Fourteen days later, patients crossover to Arm II. Receives: Dietary Supplement: Glucosamine Sulfate/Chondroitin Sulfate Tablet |
| Arm II (placebo) | Placebo comparator | Patients receive placebo PO on days 1-14 in the absence of disease progression or unacceptable toxicity. Fourteen days later, patients crossover to Arm I. Receives: Other: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of participants that experienced a shift in bacterial community assessed by operational taxonomic units
Shifts in the bacterial communities is based on clustering of operational taxonomic units (OTU) at 97% similarity
Measured: Up to 2 years

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Glucosamine Sulfate/Chondroitin Sulfate Tablet in people with Healthy Subject, run by Fred Hutchinson Cancer Center 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 1 inclusion and 11 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 24 May 2019. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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.
What does the primary outcome measure?
Number of participants that experienced a shift in bacterial community assessed by operational taxonomic units (time frame: Up to 2 years). 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 24 May 2019.
