Trial Information

Metformin for the Treatment of Endometrial Hyperplasia

This is a multi-institutional pilot clinical trial designed to estimate the response rate
and safety of metformin for the treatment of simple and complex endometrial hyperplasia (EH)
without atypia. Enrollment of patients will occur at UNC-Chapel Hill and Southern Pines
Women's Health Center. Fifteen patients will be enrolled over the course of 1 year.
Metformin will be initiated at 850 mg orally once daily, and titrated up to twice daily over
a minimum of 1 months time. Treatment will last 12 weeks and then patients will undergo
repeat endometrial biopsy to assess for regression or persistence of EH.

endometrial biopsy

- Have normal serum transaminase values (AST and ALT)

- Need to be able to undergo metformin treatment for a duration of 12 weeks prior to
repeat endometrial biopsy

Exclusion Criteria:

- Are currently taking metformin or have taken metformin in the past 6 months or have a
