Answer

Charpentier et al concluded that the early addition of pioglitazone in patients who are not responding to dual therapy is beneficial, decreasing HbA1c, as well as improving FPG levels and other surrogate markers. [153] In this study, patients (n=299) with type 2 diabetes mellitus uncontrolled by combination therapy with metformin and a sulfonylurea or a glinide were randomly assigned to receive add-on therapy with either pioglitazone 30 mg daily or a placebo.

Among patients with a baseline HbA1c level of less than 8.5%, 44.4% of patients in the pioglitazone group achieved an HbA1c level of less than 7% after 7 months, compared with only 4.9% of patients in the placebo group. In patients with a baseline HbA1c level of 8.5% or greater, 13% of those in the pioglitazone group achieved an HbA1c level of less than 7%, while no patients in the placebo group saw the same reduction.
