NCT06863922

Brief Summary

This pilot, genotype-stratified clinical trial aims to investigate the safety and preliminary efficacy of berberine supplementation in adult patients with type 2 diabetes mellitus (T2DM) who carry a specific high-risk TCF7L2 polymorphism (e.g., rs7903146) in the homozygous state. The study will compare improvements in glycemic control and metabolic markers between two groups: (1) homozygous carriers of the TCF7L2 "unfavorable" variant and (2) non-carriers (wild-type). It is hypothesized that berberine will yield greater reductions in HbA1c and fasting plasma glucose among homozygous carriers, potentially due to their distinct TCF7L2-mediated insulin secretion and sensitivity pathways.

Eligibility Criteria

Age30 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults (age 30-70 years) with a confirmed diagnosis of type 2 diabetes mellitus.
  • On stable doses of metformin or other standard oral antihyperglycemic agents for at least 4 weeks prior to enrollment.
  • Willingness to undergo genetic testing for TCF7L2 polymorphisms. For the Homozygous Variant Cohort: confirmed homozygous high-risk TCF7L2 polymorphism (e.g., rs7903146) prior to enrollment.
  • For the Non-Variant Cohort: confirmed wild-type TCF7L2 genotype.

You may not qualify if:

  • Current use of insulin therapy or recent (within 4 weeks) change in diabetic medications.
  • Known hypersensitivity or intolerance to berberine or related compounds.
  • Significant renal or hepatic impairment.
  • Pregnancy or breastfeeding.
  • Any other acute or chronic condition that, in the investigator's judgment, could compromise the patient's safety or the study's integrity.
