Measure
Pioglitazone, Then Placebo
Pioglitazone, 30 mg daily, was administered for the initial 2 weeks of the first treatment phase, followed by 45 mg daily for an additional 14 weeks. This was followed by a 4-week washout period. Subjects were assessed for clinical stability during a second 4-week run-in period prior to crossing over to the placebo phase for 16 weeks in the second treatment phase to receive the placebo.
Placebo, Then Pioglitazone
Placebo was administered for 16 weeks. This was followed by a 4-week washout period. Subjects were assessed for clinical stability during a second 4-week run-in period prior to crossing over to the Pioglitazone treatment group. Pioglitazone, 30 mg daily, was administered for the initial 2 weeks of the treatment phase, followed by 45 mg daily for an additional 14 weeks.
