NCT02903511

Brief Summary

This study is being done to determine if treatment with metformin, a drug widely used for the treatment of diabetes type 2, is safe and well tolerated by individuals with Autosomal Dominant Polycystic Kidney Disease (ADPKD) who are not diabetic and who have slightly decreased kidney function. The study will also evaluate the effects of metformin on kidney growth and kidney function.

Outcome Measures

Primary Outcomes (1)
