Glucosamine and Chondroitin in Preventing Inflammation in Overweight Patients

Phase 1
Completed
Conditions
Healthy Subject
Overweight
Interventions
Dietary Supplement: Glucosamine
Other: Placebo
Registration Number
NCT03827161
Lead Sponsor
Fred Hutchinson Cancer Center
Brief Summary

This trial studies glucosamine and chondroitin in preventing inflammation in overweight patients. Chronic inflammation contributes to cancer formation, and biomarkers of inflammation have been associated with cancer risk. Glucosamine and chondroitin may prevent inflammation and this trial may help identify the bacteria that help process them in the gut.

Primary Outcome Measures
NameTimeMethod
Effects of glucosamine sulfate/chondroitin sulfate tablet (G&C) on gut microbial community modulationUp to 2 years

shifts in the bacterial communities within person based on clustering of operational taxonomic units (OTU) at 97% utilizing principal coordinate analysis \[PCOA\]).

Effects of G&C on serum C-reactive protein (CRP)Up to 2 years

evaluated using a generalized estimating equation which accounts for variation due to repeated measures within an individual
