Mirena® + metformin
Mirena®
The enrolled patient is allocated to either LNG-IUS only or LNG-IUS + metformin by central randomization with study site allocation. A 90-100 days of continuous treatment before first histologic assessment of treatment response is required. The patient will receive endometrial curettage or hysteroscopic evaluation and resection of suspected lesion after 90-100 days of treatment. Patients with good response to assigned treatment will continue the treatment for another 90-100 days and second histologic assessment will be performed. Patients with poor response to assigned treatment at first assessment will receive additive oral progestin therapy, along with the assigned regimen(s) as, Oral progestin, either medroxyprogesterone acetate 500 mg daily or oral megestrol acetate 160 mg daily After a total of at least 6 months treatment period, the patient with good response at first assessment is suggested to keep the Mirena for maintenance until plan to get pregnant
