Details and patient eligibility

About

This is the first phase 3 randomized, double-blind, placebo/active-controlled clinical study to evaluate the efficacy and long-term safety of SAL067 in treatment-naive T2DM patients uncontrolled with diet and exercise intervention, comprising 24 weeks of double-blind treatment period followed by an open-label treatment period, making up a total of 52 weeks.

Full description

All eligible subjects would enter the 24 weeks of double-blind treatment period and were randomized into the SAL067 group (12 mg once daily) or alogliptin group (25 mg once daily) or placebo group at a 2:1:1 ratio. After 24 weeks of double-blind treatment, subjects would enter the extended open-label treatment period. Subjects in the placebo group were to be switched to SAL067 (12 mg once daily) treatment, while patients in the SAL067 and alogliptin groups continued the same treatment until the end of the whole 52 weeks.
