N/A
Waitlist Available
Led By Qi Dai, MD, PhD
Research Sponsored by Vanderbilt University Medical Center
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Hyperplastic polyp or/and Adenoma cases
Participants with known genotype for Thr1482Ile polymorphism in TRPM7
Must not have
Chronic renal diseases and hepatic cirrhosis
Type I diabetes mellitus
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 12 week

Summary

This trial will test whether reducing the amount of calcium relative to magnesium that a person consumes, through magnesium supplementation, has an effect on the related biomarkers of colorectal cancer.

Who is the study for?
This trial is for adults at high risk of colorectal polyps or cancer due to family history, smoking, obesity, low fiber intake, or high red meat consumption. Participants must not have a history of any cancer (except non-melanoma skin), organ transplants, gastric bypasses, certain heart conditions, chronic diarrhea or diabetes type I. They should live near Nashville for the next 6 months and agree to genetic testing.
What is being tested?
The study tests if magnesium glycinate supplements can affect biomarkers related to colorectal tumorigenesis by altering the dietary calcium/magnesium ratio. It's especially focused on individuals with a specific gene variant (1482Ile allele). Participants are randomly assigned to receive either magnesium glycinate or a placebo.
What are the potential side effects?
Potential side effects from magnesium glycinate may include digestive issues like stomach upset or diarrhea. People intolerant to this compound cannot participate in the trial.
