Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1 study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of HM17321 after single ascending doses in healthy adult participants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1, randomized, double-blind, placebo-controlled, single ascending dose study designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of HM17321 in healthy adult participants.

The study will enroll approximately 40 healthy adults with a body mass index (BMI) of ≥20 kg/m² and ≤27 kg/m². Participants will be assigned to 1 of 5 cohorts, with each cohort consisting of 8 participants (6 receiving HM17321 and 2 receiving placebo). The total sample size may be adjusted if additional dose cohorts are added and/or existing cohorts are expanded. Participants who discontinue for reasons other than safety may be replaced at the discretion of the Sponsor and Investigator.

All study drugs will be administered by subcutaneous (SC) injection into the abdominal wall.

The study will include a 28-day screening period, a 5-day inpatient stay during which a single SC dose of HM17321 or placebo will be administered, and an outpatient/follow-up period through Day 29. The study duration for each participant will be approximately 8 weeks from screening to the last follow-up visit.

Allocation Method

RANDOMIZED

Intervention Model

SEQUENTIAL

Participants in each cohort will be randomly assigned to receive either HM17321 or placebo. Dose levels will be escalated sequentially in separate cohorts after review of safety data.
Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Investigators Outcome Assessors
The study will be conducted in a double-blind manner. Participants, investigators, and outcome assessors will remain blinded to treatment assignments. Only designated unblinded personnel (e.g., pharmacist or site staff responsible for drug preparation) will have access to treatment allocation information, and they will not be involved in any other study assessments.

Study Groups
