- •Clinical endpoints for regeneration
PHASE 3
Vertical Integration
Pathway
BLA Supplement
FDA Center
CBER
Timeline
48-60 months
In-house cell sourcing and manufacturing. Supply chain control and margin optimization.
Key Milestones
Manufacturing facility qualification
Month 48
Process validation
Month 54
BLA supplement submission
Month 60
Approval and launch
Month 66
Key Considerations

Why 510(k) First?
- ✓Fastest path to market (18-24 months vs 5+ years for BLA)
- ✓Generates revenue to fund Phase 2 development
- ✓Builds clinical evidence in real-world use
- ✓Establishes manufacturing and QA systems
- ✓Creates commercial infrastructure
RMAT Designation Strategy
Regenerative Medicine Advanced Therapy (RMAT) designation may be pursued for Phase 2 product to enable:
- •Early FDA interactions
- •Rolling BLA submission
- •Priority review
- •Accelerated approval pathway
