Dimethyldiguanide Combined With Aromatase Inhibitor (AI) in Metastatic Breast Cancer
Phase II Study of Dimethyldiguanide Combined With AI Compared to AI in Postmenopausal HR(+) Metastatic Breast Cancer.

The addition of dimethyldiguanide might increase the efficacy of AI treatment in metastatic breast cancer.

The addition of dimethyldiguanide might increase the efficacy of AI in patients with metastatic breast cancer after the failure of the first line endocrine therapy.
