1. Purpose
To define the procedure for aligning Bioavailability/Bioequivalence (BA/BE) studies with global clinical development strategies, ensuring their timely inclusion in regulatory submissions, lifecycle planning, and multi-region product approvals.
2. Scope
This SOP applies to all BA/BE studies planned for integration with global clinical strategies, including those intended for the US FDA, EMA, CDSCO, PMDA, Health Canada, WHO PQ, and
other regulatory markets. It includes coordination across cross-functional teams for formulation, regulatory, and commercial alignment.
3. Responsibilities
- Global Clinical Development Lead: Ensures BA/BE studies are mapped within the overall clinical development plan (CDP).
- Regulatory Affairs: Provides input on country-specific BA/BE requirements.
- Clinical Project Manager: Oversees timelines and protocol harmonization across submissions.
- Medical Affairs: Advises on bridging studies and global value propositions.
4. Accountability
The Head of Global Clinical Development is accountable for the integration and regulatory alignment of BA/BE studies within the overall strategy for each therapeutic program.
5. Procedure
5.1 Strategic Assessment
- Review Target Product Profile (TPP) and Clinical Development Plan (CDP) for inclusion points of BA/BE studies.
- Identify the following:
- Reference products for each regulatory jurisdiction
- Bridging needs across dosage forms and strengths
- Waiver opportunities (BCS-based, formulation similarity)
5.2 Global Regulatory Mapping
- Compile applicable guidelines from global agencies using Annexure-1: Regulatory Mapping Sheet.
- Document differences in study design requirements (e.g., fasting/fed, single vs multiple-dose).
5.3 Protocol Harmonization
- Align clinical endpoints and PK parameters across protocols where submission in multiple regions is planned.
- Use Annexure-2: Global BA/BE Protocol Comparison Matrix for side-by-side review.
5.4 Lifecycle Planning
- Map BA/BE studies across:
- ANDA/505(j) submissions (US)
- Generic applications (EU)
- Post-approval changes and line extensions
- Maintain timeline using Annexure-3: Global Study Integration Tracker.
5.5 Stakeholder Review
- Conduct global clinical strategy meetings to finalize BA/BE plans with Regulatory, Formulation, and Commercial teams.
- Document meeting outcomes and update CDP accordingly.
