About

This is a Phase 2, multi-center, double-blind, placebo-controlled study of the safety and effect of PBI-4050 at doses ranging from 400 mg to 1200 mg on relevant biomarkers in subjects with inadequately-controlled T2DMS on stable background antidiabetic therapy.

Full description

This Phase 2 study will be performed by 15 sites in Canada. The total duration of study participation for each subject is approximately 20 weeks and comprises 6 study visits

A total of approximately 268 subjects will be enrolled in the study and randomly assigned to one of the following 4 treatment groups:

• PBI-4050 400 mg
• PBI-4050 800 mg
• PBI-4050 1200 mg
• Placebo

All subjects will receive the assigned study drug for 12 weeks.

Enrollment: 104 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
