Last verified: April 2017
The current study investigates Welchol as add-on therapy to pioglitazone to improve glycemic control in subjects with Type 2 Diabetes Mellitus not adequately controlled with pioglitazone monotherapy or pioglitazone in combination with either metformin or a sulfonylurea. The study will evaluate if Welchol add-on to pioglitazone therapy for Type 2 Diabetes Mellitus will be safe, well tolerated, and efficacious.

Drug: Welchol
Welchol 625 mg Tablets
Drug: Pioglitazone
patients will be on stable pioglitazone 30mg or 45 mg
Other Name: Actos
Placebo Comparator: placebo
placebo patients will be on stable pioglitazone 30mg or 45 mg

Detailed Description:

Eligible subjects will be randomly assigned to treatment with either 6 tablets of Welchol or 6 tablets of placebo. The 6 tablets are to be taken in a single dose with dinner or 2 equally divided doses taken with lunch and dinner. Randomization will be stratified by oral anti-diabetes drug therapy at the time of screening (pioglitazone monotherapy [30 mg or 45 mg] or pioglitazone combination therapy [metformin, SU, or DPP-4 inhibitor]).

During the trial, all subjects will be on a stable dose of pioglitazone monotherapy (30 mg or 45 mg).
