Working Group
� 1989: International Pharmaceutical Aerosol Consortium (IPAC) formed to address regulatory consequences for MDIs of Montreal and Kyoto Protocols
� 1999: IPAC formed a Working Group to prepare comments on the FDA draft CMC Guidances for MDIs, DPIs, Nasal Sprays, and Inhalation Solutions/Suspensions
� 2001: International Pharmaceutical Aerosol Consortium for Regulation and Science (IPAC-RS) formed as a separate Consortium
Mission: To advance consensus-based, scientifically driven standards
and regulations that facilitate availability of high-quality, safe and
efficacious orally inhaled and nasal drug products to patients.

Mission:
To improve packaging and device materials
quality and integrity, reduce supply chain
problems and promote rational testing
approaches.
Impact:
The Patient is best served when we provide
quality packaging and device components
that are both safe and effective through the
shelf life of the drug product.

Material Quality Affects Product Quality
“Quality refers to the physical, chemical, microbiological, biological,
bioavailability, and stability attributes that a drug product should maintain
if it is to be deemed suitable for therapeutic or diagnostic use.” FDA 1999

2009 EU & US Forum Discussion Topics
All parties within the supply chain discussed the following issues with
great enthusiasm:
� Communication - breaking the barriers
� Confidential information/data – can it be shared?
� Extraction/Biocompatibility studies – who conducts the testing?
� Material variability – what’s acceptable?
� Lifecycle management – managing post approval changes
� Regulatory expectations – what Pharma requires to file a drug
product?
16
2009 Discussion Forum Proposals
� Rationale as to why extraction studies should be conducted
by suppliers – inclusion of extraction studies expectation in
baseline requirements
� Use of analytical thresholds in extraction studies
� Establishing a reasonable threshold/limit
� 36 month availability of material
� Adequate notice period (minimum 12 months)
� Last-call option to allow bulk purchase before production
discontinuation
� Notification of changes

Continuous Improvement (initiated 2015)
• How can the “Baseline Requirements” be kept relevant to
current scientific, manufacturing, and regulatory context?
- Development and manufacturing processes are changing
- Risk management, control, and testing paradigms are changing
• Who is using them?
• How are they being used?
• What are “critical components”?
• Can these requirements be expanded to other “high-risk”
dosage forms?
26
Revision Planning
• Materials WG create draft
• Set-up meetings with stakeholder to receive feedback
- IPAC-RS Members
- Material Suppliers
- Contract Manufacturers
- Contract Analytical Testing Laboratories
- Regulators
• Final Draft Circulated
• Plan workshop
Requirement I: Material Availability
• Minimum 36 months rolling availability of unchanged material* including:
- Shelf-life of material
- Adequate notice period (minimum 12 m) to qualify new material according to
regulatory requirements
- Last-call option to allow bulk purchase before production discontinuation

Effective Risk-Based Testing Strategy
• Testing point - where the relevant knowledge exists
• Risk evaluation of safety or performance – Mitigate by testing
vs. process controls
• Critical quality attributes - properly determined
• Testing methodology- appropriate to the proposed failure mode
