About this study

Official title: A Double-blind, Randomized, Placebo Controlled, Combined Single (Part A) and Multiple (Part B, C) Ascending Dose, Phase 1 Study to Investigate the Safety, Tolerability and Pharmacokinetic and Pharmacodynamics Following Subcutaneous Injections of PG-102(MG12) in Healthy Adult and Obesity Participants

This is a Phase 1, first-in-human (FIH), randomized, double-blind, placebo-controlled, combined single (Part A) multiple (Part B, C) ascending dose, phase 1 study to investigate the safety, tolerability and pharmacokinetic and pharmacodynamics following subcutaneous injections of PG-102(MG12) in healthy adult participants.

This study will be conducted in 3 Parts (Part A, B and C), with up to 5 cohorts in each part.

Read the detailed description

Part A (SAD):

In Part A, subjects will receive a single dose of study drug, and the safety and efficacy of PG-102(MG12) will be evaluated in healthy subjects.

Part B (MAD):

In Part B, subjects will receive once-weekly doses of the study drug for 4 weeks, and the safety and efficacy of PG-102(MG12) will be evaluated in otherwise healthy overweight adult subjects.

Part C (MAD):

In Part C, obese participants will receive five repeated subcutaneous doses of the study drug, and the safety and tolerability of PG-102 (MG12) will be assessed across two cohorts based on prior safety data from Part B.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PG-102(MG12) in people with Healthy and Overweight, run by ProGen. Co., Ltd. at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with treatment-emergent adverse events (TEAEs) for Part A (time frame: Baseline to Day 29). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06309667, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 May 2025.
