Extractables & Leachables (E&L) GMP – Risk-Based Operational Guide for Defensible Decisions in FDA/EMA Audits

Extractables & Leachables (E&L) have become one of the most critical and ambiguous topics during GMP audits by FDA, AIFA, EMA, and PIC/S.
Not because “tests are missing,” but because the rationale behind decisions is often missing:
when to test, what to test, and when not to test.

Guidelines exist (USP, ICH Q9, Annex 1), but they do not explain how to make operational decisions under inspection pressure, nor how to defend them convincingly in front of an auditor.

This guide is based on real GMP audit experience and is designed for QA, QC, Regulatory, Packaging, and Validation Managers who must decide quickly, avoid over-testing, and defend their choices without grey areas.

This is not theory.
It is a guide built to save time and reduce inspection risk.

The Real Problem

In day-to-day operations, the same issues always occur:

• Everyone talks about E&L, but no one explains when they are truly mandatory
• Suppliers provide extensive dossiers that are not applicable to your specific product
• Guidelines are fragmented and each inspector interprets them differently
• Studies are performed “just to be safe,” costing months of time and budget
• Or tests are avoided… without a defensible, documented rationale

Result: slow decisions, documents rewritten multiple times, and complete uncertainty during audits.

The Concrete Value You Get

With this guide, you gain:

• Fast decisions on when E&L studies are truly required
• A significant reduction in unnecessary over-testing
• Audit-ready, risk-based rationales
• Greater confidence when facing FDA/EMA
• Less rework, fewer CAPAs, fewer surprises

It does not improve compliance “on paper.”
It saves real working days.

What the Guide Really Contains

Operational, immediately usable content:

• Step-by-step risk-based logic (ICH Q9 applied in practice)
• Real-world cases: when E&L studies are mandatory – and when they are not
• Packaging × dosage form risk matrix
• Decision flows for:
  • Plastic packaging systems
  • Elastomers
  • Single-use systems
  • Combination products
• Practical integration with:
  • USP <661.1>, <661.2>, <665>, <382>
  • EU GMP Annex 1 (2022)
• Ready-to-use templates:
  • E&L risk assessment
  • Justification for absence of E&L studies
  • Audit-ready documentation
• Most common inspection pitfalls (and how to avoid them)

👉 Each section is designed to be copied, adapted, and used immediately.

Why Buy This Guide?

• Regulations are already interpreted for you
• Decisions are clearly guided
• Typical audit questions are anticipated
• Nothing needs to be built from scratch
• It helps you avoid unnecessary studies that cost far more than the guide itself

Avoiding just one E&L study will repay the cost of this guide many times over.

Who This Guide Is For (and Who It Is Not)

Ideal for:

• QA Managers
• QC Managers
• Regulatory Affairs
• Packaging Engineering
• Validation / CSV
• Supplier Quality
• Sterile and non-sterile manufacturers

Not suitable if you:

• Are looking for a purely theoretical summary of guidelines
• Want to “study the regulation” instead of applying it
• Do not work under audit pressure

This guide is built from real inspections, not academic interpretations.
It is aligned with FDA, EMA, and PIC/S expectations and designed to be fully audit-ready.
