1. Scope and plan
2. Assess and evidence
3. Report and close gaps

Clinical research has unique risks and evidence flows. We audit sponsors, CROs, investigational sites, and vendors with the goal of protecting subjects and preserving data integrity. We align with and track changes in ICH E6, so expectations are current.
Strategic GxP Audit Frameworks: Risk-Based Comparison
| Audit Framework | Governing Regulatory Standards | Strategic Objective & Core Focus | When to Engage ADRES |
| GCP Clinical & Sponsor Audit | ICH E6 (R2/R3)FDA 21 CFR Part 312 Declaration of Helsinki | Protecting patient safety & trial data integrity. Focuses on Trial Master File (TMF) contemporaneity, Source Data Verification (SDV), informed consent compliance, Transfer of Regulatory Obligasions (TORO) and rigorous oversight of clinical CROs and analytical testing laboratories. | • Prior to Phase II/III trial initiation.• When CRO/investigational site performance drops.• 6–9 months prior to clinical data submission (NDA/BLA/MAA). |
| GMP & Supplier Qualification Audit | FDA 21 CFR 211.84 EU GMP Chapter 7 (Outsourced Activities)ICH Q10 | Mitigating supply chain & manufacturing risk. Verifies technical competence of CDMOs, API manufacturers, and critical material providers. Assesses aseptic processing (EU Annex 1 and FDA Guidance), change controls, and ensures binding Quality Agreements are enforced. | • Onboarding a new CDMO, facility, or critical vendor.• During active Tech Transfer phases.• When recurrent deviations or Out-of-Specification (OOS) results hint at systemic QMS gaps. |
| Mock FDA / EMA Inspection | ICH Q9 (Risk Management) ICH Q10 (QMS)FDA PAI Compliance Programs | Stress-testing QMS under inspection pressure. Simulates an official Pre-Approval Inspection (PAI) or routine authority visit. Identifies Critical-to-Quality (CtQ) vulnerabilities, coaches Subject Matter Experts (SMEs) in interview logistics, and establishes preemptive CAPA containment. | • Health authority or Notified Body audit is officially scheduled on the calendar.• Ahead of corporate due diligence, M&A, or institutional fundraising rounds.• Post-remediation verification. |
