# Phase 27: Clinical Trial Lifecycle - Quick Start Guide

## Overview

Complete clinical trial lifecycle management system with EDC, eConsent, adverse event reporting, and trial management.

**Story Points:** 45 | **Priority:** P1

## Quick Installation

```bash
# No dependencies required - uses Python stdlib only
cd /path/to/phase27
```

## Quick Start

### 1. Create a Clinical Trial

```python
from trial_lifecycle_core import ClinicalTrialLifecycleSystem, TrialPhase

system = ClinicalTrialLifecycleSystem()

trial = system.create_trial(
    trial_number="NCT12345678",
    title="Hypertension Treatment Study",
    phase=TrialPhase.PHASE_III,
    sponsor="Pharma Corp",
    pi="Dr. Jane Smith",
    protocol_version="v1.0",
    target_enrollment=100
)
```

### 2. Enroll Participants

```python
participant = system.enroll_participant(
    trial_id=trial.trial_id,
    site_id="SITE001",
    screening_number="SCR001",
    demographics={"age": 55, "gender": "F", "language": "en"}
)
```

### 3. Process eConsent

```python
consent_result = system.process_consent(
    participant_id=participant.participant_id,
    signature_data="Patient signature data",
    comprehension_answers={
        "purpose": "To evaluate a new treatment for high blood pressure",
        "voluntary": "Yes, I can leave the study at any time",
        "risks": "Side effects may include headache and dizziness",
        "benefits": "May help lower my blood pressure",
        "confidentiality": "My information will be kept private"
    }
)

if consent_result["success"]:
    print("✅ Consent signed successfully")
```

### 4. Enter Visit Data

```python
visit_data = system.enter_visit_data(
    trial_id=trial.trial_id,
    participant_id=participant.participant_id,
    visit_id="V1",
    form_data={
        "Vitals": {
            "weight": 75.5,
            "height": 168,
            "blood_pressure_systolic": 135,
            "blood_pressure_diastolic": 85,
            "heart_rate": 72
        }
    },
    entered_by="site_coordinator"
)
```

### 5. Report Adverse Events

```python
from trial_lifecycle_core import AESeverity, AECausality
from datetime import datetime

ae = system.report_adverse_event(
    trial_id=trial.trial_id,
    participant_id=participant.participant_id,
    site_id="SITE001",
    event_term="Headache",
    event_description="Mild headache, resolved with acetaminophen",
    severity=AESeverity.GRADE_1,
    causality=AECausality.POSSIBLE,
    onset_date=datetime.now()
)
```

### 6. Generate Trial Dashboard

```python
dashboard = system.generate_trial_dashboard(trial.trial_id)

print(f"Enrolled: {dashboard['enrollment']['total_participants']}")
print(f"Consents signed: {dashboard['consents']['signed']}")
print(f"Total AEs: {dashboard['safety']['total_aes']}")
print(f"Trial health: {dashboard['overall_health']}")
```

## Key Features

### Trial Management
- Multi-site trial coordination
- Participant screening & enrollment
- Randomization to treatment arms
- Protocol compliance tracking

### Electronic Consent (eConsent)
- Digital consent forms
- Comprehension assessment (5 questions, 80% pass threshold)
- Digital signatures (SHA-256)
- Consent withdrawal tracking
- Multi-language support

### Adverse Event Reporting
- CTCAE v5.0 severity grading (Grades 1-5)
- Causality assessment (Naranjo algorithm)
- Serious Adverse Event (SAE) auto-flagging
- Regulatory reporting (IRB, Sponsor, FDA)

### Electronic Data Capture (EDC)
- Case Report Form (CRF) data entry
- Real-time validation
- Query management
- Data verification (SDV)
- Data locking
- CDISC SDTM export

## Regulatory Compliance

✅ **21 CFR Part 11** - FDA Electronic Records & Signatures
✅ **GCP** - Good Clinical Practice
✅ **HIPAA** - PHI protection via hashing
✅ **GDPR** - Data protection & privacy
✅ **CDISC** - Data standards (SDTM)
