ICH Q3E Draft Gives Global Framework
The FDA published a draft ICH Q3E guidance on December 1, 2025 that gives drug makers a holistic, risk-based framework to assess and control extractables and leachables to help ensure patient safety and product quality. The ICH Assembly endorsed the draft in August 2025 and FDA is making it available for public comment as it works toward a final guidance.
New E&L Thresholds and Monographs
The draft guidance discusses thresholds for identifying, quantifying, and reporting extractables and leachables (E&L) and includes draft Class 3 leachable monographs in its supporting documentation. Drug makers will need to review these thresholds and monographs and may need to change testing, reporting, or quality-control processes accordingly.
Public Comment Deadline — Act Now
FDA requests comments on the draft Q3E guidance; comments must be submitted by January 30, 2026 for consideration before work on the final guidance. Companies that want to influence the final text or raise cost concerns should submit comments by that date.
Draft Guidance Is Non-Binding, Final Will Consider Costs
The notice states FDA guidance documents are not legally enforceable and describe the Agency's current thinking; alternative approaches that satisfy statutes/regulations remain permitted. FDA also said it will consider comments on costs or cost savings (relevant to Executive Order 14192) as it develops the final guidance.
