📚 Part of the GLPI-103 Regulatory Dossier — Reader's Guide. This article shows the live document; edits to the source appear here automatically.
This is a mock / simulation document, made for a portfolio and for learning. The drug (GLPI-103), the sponsor, the people, and the data are all fictional. It is not a real regulatory submission and has no clinical, legal, or regulatory standing. What is real is the shape of the thing — the document structure, the standards it follows, and the analysis methods; the content inside is illustrative.
What it is. An abbreviated clinical study report for the Phase 2 proof-of-concept / dose-finding study.
Why it exists. Phase 2 chooses the dose(s) for Phase 3 by comparing several doses against control. Its results are the basis for the End-of-Phase-2 discussion with regulators and the pivotal-trial design.
How it is produced here. This is an early-phase (first-in-human / Phase 2) report written as a short narrative. It is a portfolio stand-in, kept deliberately consistent with the rest of the program (the doses, the pharmacology, the safety story all line up).
Format & governing standard. ICH E3 (abbreviated report)

|---|---|---|---|
| 1.0 | 2026-06-29 | Clinical / Biostatistics | Initial abbreviated CSR |
| 2.0 | 2026-06-30 | Clinical / Biostatistics | Expanded to fuller ICH E3 structure (ethics, design, dose-response, safety) |

| Item | Description |
|---|---|
| Design | Phase 2, randomized, double-blind, placebo-controlled, parallel-group dose-finding (PoC) |
| Population | Adults with T2DM on metformin |
| N | 240 (4 arms × 60: placebo, low, medium, high) |
| Duration | 24 weeks (with titration) |
| Primary endpoint | Change from baseline in HbA1c at Week 24 |
| Key secondary | Body weight; HbA1c <7.0%; cardiometabolic biomarkers |
Conducted per the Declaration of Helsinki, ICH E6(R3) GCP, and applicable regulations, with IRB/IEC approval, written informed consent, and independent DSMB safety oversight. Multicentre (Republic of Korea) [MOCK].
Establish proof of concept and characterize the dose–response for HbA1c to select the Phase 3 doses; assess body weight, cardiometabolic biomarkers, and safety/tolerability.
[MOCK]| Arm | Randomized | Completed 24 wk | Discontinued |
|---|---|---|---|
| Placebo | 60 | 54 | 6 |
| Low | 60 | 53 | 7 |
| Medium | 60 | 52 | 8 |
| High | 60 | 50 | 10 |
| Total | 240 | 209 | 31 |
Discontinuations were modestly higher at the high dose, predominantly for gastrointestinal tolerability, consistent with the class exposure–tolerability gradient. Baseline characteristics were comparable across arms (mean age ~58 y; HbA1c ~8.2%; BMI ~29 kg/m²).
[MOCK]| Endpoint at Week 24 | Placebo | Low | Medium | High |
|---|---|---|---|---|
| HbA1c CFB (%) | −0.3 | −1.1 | −1.7 | −2.1 |
| Body-weight CFB (kg) | −0.8 | −3.5 | −6.0 | −8.0 |
| HbA1c <7.0%, % | 12 | 38 | 55 | 68 |
[MOCK]The most common adverse events were gastrointestinal (nausea, vomiting, diarrhoea), dose-related and titration-manageable, predominantly mild–moderate. There were no treatment-related serious adverse events and no deaths; laboratory, ECG, and vital-sign parameters showed no clinically significant trends. Hypoglycaemia was infrequent on the metformin background.
GLPI-103 demonstrated proof of concept with a clear, monotonic dose–response for glycaemic and weight effects and a manageable safety profile, de-risking the program and supporting the Phase 3 doses (GLPI103-301; REF-002). This study was the Gate-3 decision point for major Phase 3 investment (PM-002/PM-003).
As a 24-week Phase 2 study the report does not address long-term durability or rare events; efficacy estimates are illustrative [MOCK] and were confirmed in the data-anchored pivotal study. Cardiometabolic-biomarker findings are exploratory.
