## Regulatory Strategy Workflow

Develop regulatory strategy aligned with business objectives and product characteristics.

### Workflow: New Product Regulatory Strategy

1. Gather product information:
   - Intended use and indications
   - Device classification (risk level)
   - Technology platform
   - Target markets and timeline
2. Identify applicable regulations per target market:
   - FDA (US): 21 CFR Part 820, 510(k)/PMA/De Novo
   - EU: MDR 2017/745, Notified Body requirements
   - Other markets: Health Canada, PMDA, NMPA, TGA
3. Determine optimal regulatory pathway:
   - Compare submission types (510(k) vs De Novo vs PMA)
   - Assess predicate device availability
   - Evaluate clinical evidence requirements
4. Develop regulatory timeline with milestones
5. Estimate resource requirements and budget
6. Identify regulatory risks and mitigation strategies
7. Obtain stakeholder alignment and approval
8. **Validation:** Strategy document approved; timeline accepted; resources allocated

### Regulatory Pathway Selection Matrix

| Factor | 510(k) | De Novo | PMA |
|--------|--------|---------|-----|
| Predicate Available | Yes | No | N/A |
| Risk Level | Low-Moderate | Low-Moderate | High |
| Clinical Data | Usually not required | May be required | Required |
| Review Time | 90 days (MDUFA) | 150 days | 180 days |
| User Fee | ~$22K (2024) | ~$135K | ~$440K |
| Best For | Me-too devices | Novel low-risk | High-risk, novel |

## FDA Submission Workflow

Prepare and submit FDA regulatory applications.

### Workflow: 510(k) Submission

1. Confirm 510(k) pathway suitability:
   - Predicate device identified (note K-number, e.g., K213456)
   - Substantial equivalence (SE) argument supportable on intended use and technological characteristics
   - No new intended use or technology concerns triggering De Novo
2. Schedule and conduct Pre-Submission (Q-Sub) meeting if needed (see [Pre-Sub Decision](#pre-submission-meeting-decision))
3. Compile submission package checklist:
   - [ ] Cover letter with device name, product code, and predicate K-number
   - [ ] Section 1: Administrative information (applicant, contact, 510(k) type)
   - [ ] Section 2: Device description — include photos, dimensions, materials list
   - [ ] Section 3: Intended use and indications for use
   - [ ] Section 4: Substantial equivalence comparison table (see example below)
   - [ ] Section 5: Performance testing — protocols, standards cited, pass/fail results
   - [ ] Section 6: Biocompatibility summary (ISO 10993-1 risk assessment, if patient contact)
   - [ ] Section 7: Software documentation (IEC 62304 level, cybersecurity per FDA guidance, if applicable)
   - [ ] Section 8: Labeling — final draft IFU, device label
   - [ ] Section 9: Summary and conclusion
4. Conduct internal review and quality check against FDA RTA checklist
5. Prepare eCopy per FDA format requirements (PDF bookmarked, eCopy cover page)
6. Submit via FDA ESG portal with user fee payment
7. Monitor MDUFA clock and respond to AI/RTA requests within deadlines
8. **Validation:** Submission accepted; MDUFA date received; tracking system updated

#### Substantial Equivalence Comparison Example

| Characteristic | Predicate (K213456) | Subject Device | Same? | Notes |
|----------------|---------------------|----------------|-------|-------|
| Intended use | Wound measurement | Wound measurement | ✓ | Identical |
| Technology | 2D camera | 2D + AI analysis | ✗ | New TC; address below |
| Energy type | Non-energized | Non-energized | ✓ | |
| Patient contact | No | No | ✓ | |
| SE conclusion | New TC does not raise new safety/effectiveness questions; bench data demonstrates equivalent accuracy (±2mm vs ±3mm predicate) |

### Workflow: PMA Submission

1. Confirm PMA pathway:
   - Class III device or no suitable predicate
   - Clinical data strategy defined
2. Complete IDE clinical study if required:
   - IDE approval
   - Clinical protocol execution
   - Study report completion
3. Conduct Pre-Submission meeting
4. Compile PMA submission checklist:
   - [ ] Volume I: Administrative, device description, manufacturing
   - [ ] Volume II: Nonclinical studies (bench, animal, biocompatibility)
   - [ ] Volume III: Clinical studies (IDE protocol, data, statistical analysis)
   - [ ] Volume IV: Labeling
   - [ ] Volume V: Manufacturing information, sterilization
5. Submit original PMA application
6. Address FDA questions and deficiencies
7. Prepare for FDA facility inspection
8. **Validation:** PMA approved; approval letter received; post-approval requirements documented

### FDA Submission Timeline

| Milestone | 510(k) | De Novo | PMA |
|-----------|--------|---------|-----|
| Pre-Sub Meeting | Day -90 | Day -90 | Day -120 |
| Submission | Day 0 | Day 0 | Day 0 |
| RTA Review | Day 15 | Day 15 | Day 45 |
| Substantive Review | Days 15–90 | Days 15–150 | Days 45–180 |
| Decision | Day 90 | Day 150 | Day 180 |

### Common FDA Deficiencies and Prevention

| Category | Common Issues | Prevention |
|----------|---------------|------------|
| Substantial Equivalence | Weak predicate comparison; no performance data | Build SE table with data column; cite recognized standards |
| Performance Testing | Incomplete protocols; missing worst-case rationale | Follow FDA-recognized standards; document worst-case justification |
| Biocompatibility | Missing endpoints; no ISO 10993-1 risk assessment | Complete ISO 10993-1 matrix before testing |
| Software | Inadequate hazard analysis; no cybersecurity bill of materials | IEC 62304 compliance + FDA cybersecurity guidance checklist |
| Labeling | Inconsistent claims vs. IFU; missing symbols standard | Cross-check label against IFU; cite ISO 15223-1 for symbols |

### Workflow: MDR Technical Documentation

1. Confirm device classification per MDR Annex VIII
2. Select conformity assessment route based on class:
   - Class I: Self-declaration
   - Class IIa/IIb: Notified Body involvement
   - Class III: Full NB assessment
3. Select and engage Notified Body (for Class IIa+) — see selection criteria below
4. Compile Technical Documentation per Annex II checklist:
   - [ ] Annex II §1: Device description, intended purpose, UDI
   - [ ] Annex II §2: Design and manufacturing information (drawings, BoM, process flows)
   - [ ] Annex II §3: GSPR checklist — each requirement mapped to evidence (standard, test report, or justification)
   - [ ] Annex II §4: Benefit-risk analysis and risk management file (ISO 14971)
   - [ ] Annex II §5: Product verification and validation (test reports)
   - [ ] Annex II §6: Post-market surveillance plan
   - [ ] Annex XIV: Clinical evaluation report (CER) — literature, clinical data, equivalence justification
5. Establish and document QMS per ISO 13485
6. Submit application to Notified Body
7. Address NB questions and coordinate audit
8. **Validation:** CE certificate issued; Declaration of Conformity signed; EUDAMED registration complete

#### GSPR Checklist Row Example

### Clinical Evidence Requirements by Class

| Class | Clinical Requirement | Documentation |
|-------|---------------------|---------------|
| I | Clinical evaluation (CE) | CE report |
| IIa | CE with literature focus | CE report + PMCF plan |
| IIb | CE with clinical data | CE report + PMCF + clinical study (some) |
| III | CE with clinical investigation | CE report + PMCF + clinical investigation |

### Notified Body Selection Criteria

- **Scope:** Designated for your specific device category
- **Capacity:** Confirmed availability within target timeline
- **Experience:** Track record with your technology type
- **Geography:** Proximity for on-site audits
- **Cost:** Fee structure transparency
