Brief Summary
This is a randomized, double-blind, placebo-controlled, repeat-dose study to evaluate the safety, tolerability, PK, and PD of L47 as an add-on treatment to stable metformin therapy in patients with T2DM. Approximately 30 subjects will be randomized into the study at up to two investigational sites. The study includes a screening period of up to 28 days, with a three-day, single-blind, placebo lead-in period; a four-week, double-blind treatment period; and a one-week follow-up period. There will be 2 inpatient stays (Day -3 to 2 and 27 to 29) and daily outpatient visits during treatment period. During the follow-up period, there will be 1 outpatient visit at the end of the study. There will be 3 cohorts of 10 subjects each to be enrolled sequentially. In each cohort, subjects will be randomized in a 4:1 ratio to receive either L47 or placebo subcutaneously. Subjects will monitor fasting capillary glucose (finger sticks or self-monitoring of blood glucose, SMBG) during the lead-in, treatment, and follow-up periods.
