Description of intervention(s) / exposure
GSBR-1290 is an orally available Glucagon-like peptide receptor agonist (GLP-1RA) being developed for the treatment of Type 2 Diabetes Mellitus (T2DM) and obesity. 24 Participants have been dosed to date. 48 Healthy volunteers total will be enrolled in a total of 6 cohorts (Cohorts 1 to 6) in this study. Each Cohort will enroll 8 participants with 6 participants randomized to receive GSBR-1290 and 2 participants randomized to receive placebo. All doses will be supervised and documented by site staff. GSBR-1290 oral capsule will be provided at different ascending dose levels cohorts. Cohorts 1, 2, 3, 5 and 6 will receive doses in the range of 1mg to 540mg of GSBR-1290 and placebo on Day 1 orally. Cohort 4 will receive 90mg, or other dose to be determined by the Safety Review Committee in the range of 1mg to 540mg, GSBR-1290 or placebo administered on Day 1 under fasted conditions and another dose administered on Day 4 under fed conditions with total of 2 doses being administered orally.

Dose levels for each cohort may change based on emerging safety and PK data upon review by the Safety Review Committee (SRC) meeting following each cohort. Cohorts will be does in a sequentially escalating order, unless the SRC determines otherwise in the interest of participant safety. If participants experience any clinically significant AEs during the confinement period, they may remain in the clinical facility for further observation at the discretion of the PI.
