简要总结

The purpose of this study is to evaluate the safety, tolerability, and PK of RM-718 in healthy subjects with obesity and in patients with MC4R Pathway Impairment

详细描述

This is a first-in-human and first-in-patient, 4-part study that includes the evaluation of safety, tolerability, and PK of: single ascending doses (SAD) of RM-718 weekly (RM-718) in healthy subjects 18 to 55 years of age with obesity (Part A), multiple ascending doses (MAD) of RM-718 in healthy subjects 18 to 55 years of age with obesity (Part B), MAD of RM-718 in patients 12 to 65 years of age with HO (Part C), and MAD of RM-718 in patients with PWS (Part D). Cohorts in Parts A and B are double-blind, placebo-controlled, and randomized 2:1 (4 subjects receive RM-718, 2 subjects receive placebo). Part C evaluates open-label dose escalation in patients 12 to 65 years of age with HO. Part D evaluates open-label dose escalation in patients 12 to 65 years of age. Study participants will receive: 1 weekly dose of either RM-718 or placebo in Part A, 4 weekly doses of either RM-718 or placebo in Part B,16 weekly doses of open-label RM-718 in Part C, and 26 weekly doses of RM-718 in Part D. Study drug (RM-718 or placebo) doses are administered weekly via subcutaneous injection.
