Type 2 diabetes is rapidly increasing worldwide, and there have been many advances in the care of diabetic patients. Nevertheless, less than half of the patients are achieving the glycemic goal of HbA1c < 7%. This shows that current therapeutic modalities have limitations, and the need for continued development of new antidiabetic drugs is clear. In 2007, a meta-analysis focusing on the thiazolidinedione drug rosiglitazone suggested an unacceptably high cardiovascular risk for this newly approved drug, prompting changes in regulations for antidiabetic drug development. The FDA guidance for Diabetes Mellitus-Evaluation of Cardiovascular Risk in New Antidiabetic Therapies to Treat Type 2 Diabetes was released as a draft in Feb 2008, and the final form was published in December 2008. The guidance, though not a regulation, requires developers to demonstrate that all new antidiabetic agents have an acceptable cardiovascular risk. The European Medicine Agency (EMA) also published a draft guideline in January 2010 on the clinical investigation of medicinal products for the treatment of diabetes mellitus which included a cardiovascular safety assessment component. Considering the increased CV risk in type 2 diabetic patients, antidiabetic drugs should not result in an unacceptable increase in cardiovascular risk. The FDA has offered guidelines for the assessment of cardiovascular safety for antidiabetic drugs. Careful prospective planning of clinical trials (choice of study type, subject selection, and meta-analysis) and thorough preclinical safety assessment (choice of cardiovascular endpoints: MACE, endpoint adjudication) are needed to assess possible cardiovascular risk.

OBJECTIVE: The aim of this study was to investigate the effect of insulin sensitizing agents on hormonal and metabolic parameters as well as menstrual patterns in women with polycystic ovary syndrome (PCOS). METHODS: One hundred and twenty-three patients with PCOS were included. Metformin was administered to patients at 1,500 mg or 1,700 mg daily for 3 months. If the patients had no improvement of the menstrual cycle or metformin-related adverse effects developed, the patients changed medication to a daily dose of either 15 mg pioglitazone or up to 45 mg. Then resumption of a regular menstrual cycle or recovery of ovulation was evaluated. Hormonal and metabolic profiles were compared between the response and non-response group to insulin sensitizing agents. RESULTS: One hundred and five patients with PCOS were treated with metformin for 3 months. Forty-eight patients (45.7%) showed improvement of menstrual cycle regularity after 3 months of metformin use, whereas 57 patients (54.3%) had no change. The mean free testosterone measured after 3 months of treatment was significantly lower in metformin responders than in non-responders. The other parameters did not differ between the groups. Of the 23 patients who used pioglitazone for 3 to 6 months, 19 patients (82.6%) showed improvement in their menstrual cycles. CONCLUSION: Metformin treatment seems to be effective for the improvement of menstrual cyclicity irrespective of insulin resistance in women with PCOS. When metformin related adverse effect occurred, pioglitazone would be effective for aiding the resumption of the menstrual cycle.
