Purpose

This first-in-human study will evaluate the safety, tolerability, and pharmacokinetics of single and multiple ascending oral doses of ACCG-2671. It will also evaluate the effect of food on the pharmacokinetics, safety, and tolerability of a single dose. Parts 1 and 2 will enroll healthy participants, and Part 3 will enroll otherwise healthy participants with obesity.

Detailed Description

ACCG-2671 is a nonpeptide dual amylin and calcitonin receptor agonist (DACRA) This study comprises 3 parts: Part 1 (Single Ascending Dose [SAD]) will be conducted in healthy participants to assess the safety, tolerability, and PK profile of a single oral dose of ACCG-2671 or -matched placebo (SAD Cohorts 1 through 5). Part 2 (Food Effect) will be conducted in healthy participants to assess the effect of food intake on the PK, safety, and tolerability of a single oral dose of ACCG-2671 under fasted and fed conditions. Part 3 (Multiple Ascending Dose [MAD]) will be conducted in otherwise healthy, participants with obesity (BMI ≥ 30 kg/m2) to assess the safety, tolerability, PK profiles of ACCG-2671 or matched placebo administered for 84 days (MAD Cohorts 1 through 5) Safety Review Committee (SRC) meetings will be held prior to dose escalation for Part 1 (SAD) and Part 3 (MAD) cohorts in the study. The decisions on dose escalation will be based on safety and laboratory data and available PK data from each cohort.
