Issue & CAPA Log — GLPI-103 Program

Confidentiality Confidential

Central register of program issues and Corrective and Preventive Actions (CAPA) across CMC, nonclinical, clinical, and data-pipeline workstreams. Each entry records the issue, root-cause analysis, correction, corrective and preventive action, and verification before closure — the program's worked record of issue management.

Version Date Author Summary
1.0 2026-06-29 Quality Assurance Initial log (resolved data-pipeline issues)
2.0 2026-06-30 Quality Assurance Expanded — added CMC manufacturing/analytical/stability, nonclinical, and clinical issues with full RCA/CAPA

A. Data-Pipeline / Analysis Issues

ID Severity Description Root cause Corrective action Preventive action Status
ISS-001 High TFL Table 1 identical across arms Broken pivot collapsed arms Rewrote generate_table1 per-arm verify_pipeline "Table 1 differs by arm" Closed
ISS-002 High TEAE table/prop-test hardcoded vs AE data Demonstration hardcode Derived from ae_events.csv reconcile/verify safety checks Closed
ISS-003 High ADSL strata randomly generated build_adsl rng.choice Carry real STRAT from IRT record "STRAT≈baseline" check Closed
ISS-004 Medium SC Korean values garbled in XPORT cp949/UTF-8 in XPORT v5 Map to English CDISC CT validate_cdisc CT checks Closed
ISS-005 Low Build crash on em-dash (cp949 console) Non-ASCII console output ASCII console messages — Closed
ISS-006 Medium 5 docs missing Change History Template not applied Added Change History check_format C2 (R1) Closed
ISS-016 Medium SDTM DM did not carry 2 deaths present in AE/ADSL Death flag not propagated when data enrichment added deaths Derive DM DTHFL/DTHDTC from disposition DM↔AE↔ADSL death-count cross-check Closed
ISS-017 Low config.yaml parameters inconsistent with code/data Config not wired to the build path Corrected values + documented authoritative source — Closed

B. CMC / Manufacturing & Analytical Issues

ID Severity Description Root-cause investigation Corrective action Preventive action (CAPA) Status
ISS-007 High OOS — IV drug product: batch DP-IV-003 exceeded the sub-visible-particle / aggregate limit (SE-HPLC 2.4% vs ≤2.0%) Temperature excursion of bulk solution during a hold step promoted interfacial aggregation; confirmed by reproduction study Batch rejected; investigation per OOS SOP (Phase Ia/Ib) Increased polysorbate-80 control range; added a bulk-hold temperature CPP + alarmed monitoring; re-trained operators Closed
ISS-008 High OOT — oral tablet stability: a 40 °C/75% RH batch trended toward the related-substances limit by 6 months Moisture ingress; desiccant capacity insufficient for the hygroscopic SNAC/peptide tablet Extended testing + risk assessment (no marketed impact) Packaging change to Alu/Alu blister (primary) / increased desiccant (HDPE); tightened water-content release limit Closed
ISS-009 Medium Analytical method transfer: related-substances RP-HPLC gave variable resolution of a critical impurity pair at the QC site Column lot-to-lot selectivity variability Re-qualified the transfer with bracketing standards Added column-qualification (system-suitability resolution ≥1.5) and a designated column chemistry to the method (M3-AMV) Closed
ISS-010 Medium PPQ deviation: drug-substance PPQ batch 2 showed a transient blend/charge inhomogeneity flag at the lyophiliser load Uneven shelf loading at scale Batch met all CQAs (deviation assessed not impacting quality) Revised loading pattern + IPC; added to CPV monitoring Closed
ISS-011 Medium Impurity above ID threshold: an early DS lot showed a des-Gly deletion sequence at 0.18% Incomplete coupling at a sterically hindered residue Re-purified; impurity structurally characterised & qualified (Q3A) Switched the difficult coupling to a pre-formed dipeptide fragment; added coupling-completion IPC Closed

C. Nonclinical Issues

ID Severity Description Investigation Action Status
ISS-012 High Carcinogenicity finding: dose-related thyroid C-cell hyperplasia/adenoma in the 2-year rat Mechanistic follow-up (C-cell GLP-1R density, calcitonin, species comparison) established the effect as rodent-specific Human-relevance assessment filed (M4-2.3 §4); risk carried as a labeled class contraindication (MTC/MEN-2) + RMP Closed (managed)
ISS-013 Medium Bioanalytical interference: ADA assay drug-tolerance insufficient at high concentrations Free-drug interference in the bridging ELISA Added acid-dissociation pre-treatment; re-validated Closed

D. Clinical / Operational Issues

ID Severity Description Investigation Action Status
ISS-014 Medium Enrollment: screen-failure rate ~45% vs ~30% planned → slower randomization Realistic source-population HbA1c/BMI distribution stricter than assumed Activated additional sites; protocol re-training on eligibility Closed (documented in CSR-301 §10.1; PROT deviation note)
ISS-015 Low Visit-window deviations flagged by DQE (>±7 days) Site scheduling around holidays Queries issued & resolved; categorised minor (no PPS impact) Closed (QA-002; DQE query log)

Process

Issues are logged with severity and a documented root-cause analysis (e.g., fishbone/5-Whys); a correction addresses the immediate issue and a CAPA (preferably verified by an automated check or a validated control) is implemented before closure. Quality-impacting issues are escalated to program governance per PM-005; CMC issues feed the Product Quality Review and Continued Process Verification (M3-PV).
