Brief summary

To investigate the safety and efficacy of long-term treatment with pioglitazone (Actos tablets) in combination with biguanides (for 12 months after the start of pioglitazone tablets treatment) in patients with type 2 diabetes mellitus.

Detailed description

This is a special drug use surveillance with an observation period of 12 months designed to investigate the safety and efficacy of pioglitazone (Actos) in the routine clinical setting in patients with type 2 diabetes mellitus who responded inadequately to treatment with biguanides in addition to diet therapy and exercise therapy (planned sample size, 1000). The usual adult dosage is 15 to 30 mg of pioglitazone administered orally once daily before or after breakfast. Dose adjustment will be made according to gender, age, and symptoms with an upper limit of 45 mg.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants Reporting One or More Adverse Drug ReactionsBaseline up to 12 monthsAdverse drug reactions are defined as adverse events (AEs) which are in the investigator's opinion of causal relationship to the study treatment. AEs are defined as any unfavorable and unintended signs, symptoms or diseases temporally associated with the use of a medicinal product reported from the first dose of study drug to the last dose of study drug.
Number of Participants Reporting One or More Serious Adverse Drug ReactionsBaseline up to 12 monthsSerious adverse drug reactions are defined as serious adverse events (SAEs) which are in the investigator's opinion of causal relationship to the study treatment. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

MeasureTime frameDescription
Change From Baseline in Body WeightBaseline, Months 3, 6, 9, 12 and final assessment (up to Month 12)Change relative to baseline in participant's weight measured at 3 months, 6 months, 9 months, 12 months or final visit (last visit for a participant in the study, up to Month 12).
Change From Baseline in Glycosylated Hemoglobin (HbA1c)Baseline, Months 3, 6, 9, 12 and final assessment (up to Month 12)The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at 3 months, 6 months, 9 months, 12 months or final visit (last visit for a participant in the study, up to Month 12) relative to baseline.
Change From Baseline Homeostasis Model Assessment of Insulin Resistance (HOMA-IR)Baseline, Months 3, 6, 9, 12 and final assessment (up to Month 12)The change between homeostasis model assessment of insulin resistance collected at 3 months, 6 months, 9 months, 12 months or final visit (last visit for a participant in the study, up to Month 12) relative to baseline. Homeostasis Model assessment of insulin resistance Measures insulin resistance, calculated by insulin times glucose, divided by a constant (22.5). A higher score indicates higher insulin resistance.
Change From Baseline in Immunoreactive Insulin (IRI)Baseline, Months 3, 6, 9, 12 and final assessment (up to Month 12)The change in the value of IRI (portion of insulin in blood measured by immunochemical methods for the hormone; presumed to represent the free \[unbound\] and biologically active fraction of total blood insulin) collected at 3 months, 6 months, 9 months, 12 months or final visit (last visit for a participant in the study, up to Month 12) relative to baseline.
Change From Baseline in Fasting Blood GlucoseBaseline, Months 3, 6, 9, 12 and final assessment (up to Month 12)The change between the fasting blood glucose value collected at 3 months, 6 months, 9 months, 12 months or final visit (last visit for a participant in the study, up to Month 12) relative to baseline.
