1.2 Key Terminology Table
| Term | Causality Required? | Seriousness? | Example |
|---|---|---|---|
| AE | No | No | Nausea during trial |
| AR | Yes (Possible+) | No | Rash after drug dose |
| SAE | No | Yes | Hospitalization |
| SAR | Yes | Yes | Unexpected hospitalization from drug |
| ADR | Yes | Yes (varies) | Post-marketing term for AR |
| UP | Yes | Yes | Data breach |
1.3 Critical Distinctions
AE vs. AR:
- Causality is the distinguishing factor
- Both are documented
- AR is subset of AE
SAE vs. SAR:
- Causality is the distinguishing factor
- Both are documented
- SAR is subset of SAE
- SAR gets expedited FDA reporting (if unexpected)
SAE vs. Important Medical Event:
- Important Medical Event is ONE OF six SAE criteria
- All Important Medical Events are SAE
- Not all SAE are Important Medical Events
SECTION 2: SAE CRITERIA FRAMEWORK
2.1 The Six Criteria (B-CHILD)
1. DEATH
- Most straightforward
- Any death during trial = SAE
- Causality determines if also SAR
2. LIFE-THREATENING
- Substantial risk of death AT TIME OF EVENT
- Event itself was critical (not hindsight)
- Examples: Anaphylaxis, septic shock, massive MI with hemodynamic instability
3. INPATIENT HOSPITALIZATION
- Admission + overnight stay
- Planned procedures sometimes excluded
- All unplanned hospitalizations = SAE
4. DISABILITY/INCAPACITY
- PERSISTENT significant functional loss
- Temporary symptoms don't count
- Examples: Residual stroke paralysis, hearing loss
5. CONGENITAL ANOMALY
- Birth defect from fetal drug exposure
- NEW anomalies (not pre-existing)
- Includes structural and functional defects
6. IMPORTANT MEDICAL EVENT
- Clinically significant
- Requires medical intervention
- "Catch-all" for serious diagnoses
- Examples: Cancer, MI (even if mild), serious infection diagnosis
2.2 Application Scenarios
Scenario: Severe Symptom, No SAE Criterion
- Patient: Severe (9/10) headache
- Duration: 2 hours at home
- Outcome: Full recovery
- Classification: NOT SAE (no criterion met)
- Key Point: Severity ≠ Seriousness
Scenario: Mild Symptom, Meets SAE Criterion
- Patient: Mild fever and malaise
- Outcome: Admitted for monitoring overnight
- Classification: SAE (hospitalization)
- Key Point: Outcome-based, not symptom-based
SECTION 3: SERIOUS VS. SEVERE DISTINCTION
3.1 Definition and Framework
SERIOUS:
- Based on: OUTCOME/CONSEQUENCE
- Determined by: Meeting one of six SAE criteria
- Independency: Can be serious without severe
- Examples:
- Any hospitalization (even if mild symptoms)
- Cancer diagnosis (even if asymptomatic)
- Mild hospitalization = SERIOUS
- Important medical event requiring intervention = SERIOUS
SEVERE:
- Based on: INTENSITY/MAGNITUDE
- Determined by: Grading scale (mild/moderate/severe)
- Independency: Can be severe without serious
- Examples:
- 9/10 pain that resolves at home = SEVERE (not serious)
- Pronounced rash in ED, discharged same day = SEVERE (not serious)
- Intense vomiting for 1 hour = SEVERE (not serious unless hospitalized)

3.3 SOCRA Favorite Test Questions
Question Type 1: "Severe symptoms that resolve at home"
- Answer: NOT serious (despite severity)
Question Type 2: "Mild symptoms requiring hospitalization"
- Answer: SERIOUS (despite mild severity)
Question Type 3: "Important medical event with minimal symptoms"
- Answer: SERIOUS (diagnosis/intervention required)
SECTION 4: IND SAFETY REPORTING REQUIREMENTS (21 CFR 312.32)
4.1 The Three Report Categories
7-DAY REPORTS (Most Urgent)
Criteria (ALL THREE required):
- Fatal OR Life-threatening (outcome)
- AND Unexpected (vs. IB)
- AND Suspected adverse reaction (reasonable possibility of causation)
Format:
- PHONE: Within 7 calendar days
- WRITTEN: Within 15 calendar days (follow-up)
- BOTH required
Rationale: Most serious, unexpected events
15-DAY REPORTS
Criteria (ALL THREE required):
- Serious (NOT fatal or life-threatening) (outcome)
- AND Unexpected (vs. IB)
- AND Suspected adverse reaction (reasonable possibility of causation)
Format:
- WRITTEN only: Within 15 calendar days
- No phone required
Rationale: Serious but not immediately life-threatening
NOT EXPEDITED
When to use:
- Event is expected (vs. IB) — even if serious + causality
- Event is not serious
- Event has no reasonable possibility of causation
- Event is AE only (not AR)
Reporting Method:
- Documented in study records
- Included in annual report
- Not expedited FDA notification
4.2 Decision Tree for Report Classification
ADVERSE EVENT IDENTIFIED
↓
Is there reasonable possibility
of causation (Suspected AR)?
├─ NO → STOP
│ NOT EXPEDITED
│
└─ YES ↓
Is the event UNEXPECTED
(vs. Investigator's Brochure)?
├─ NO → STOP
│ NOT EXPEDITED
│
└─ YES ↓
Does the event meet one
of six SAE criteria?
├─ NO → STOP
│ NOT EXPEDITED
│
└─ YES ↓
Is it FATAL or LIFE-THREATENING?
├─ YES → 7-DAY REPORT
│ (Phone + Written)
│
└─ NO → 15-DAY REPORT
(Written Only)
4.3 Key Regulatory Definitions
Sponsor Awareness = DAY 0
- NOT event date
- NOT investigator awareness date
- When sponsor becomes aware through any source
Calendar Days
- Includes weekends and holidays
- NOT business days
- Count continuously
"Reasonable Possibility of Causation"
- Includes: Possible, Probable, Definite
- Does NOT require: Proven causation
- Threshold: Cannot reasonably exclude
SECTION 5: CAUSALITY ASSESSMENT FRAMEWORK
5.1 Five-Level Causality System
| Level | Definition | AR Classification? |
|---|---|---|
| Unrelated | Causation clearly excluded | NO |
| Unlikely | Alternative explanations more likely | NO |
| Possible | Cannot reasonably exclude causation | YES ✓ |
| Probable | Reasonable basis for causation | YES ✓ |
| Definite | Causation with reasonable certainty | YES ✓ |
5.2 Five Assessment Factors
1. TEMPORAL RELATIONSHIP
- Timing of event relative to drug
- Immediate/rapid onset = supports causality
- Remote timing = weakens but doesn't exclude
2. DECHALLENGE
- Effect of stopping drug
- Improvement on discontinuation = supports
- No change = less supportive
3. RECHALLENGE
- Effect of restarting drug
- Recurrence = strong support
- No recurrence = challenges
- Rarely done for safety
4. ALTERNATIVE EXPLANATIONS
- How well alternatives explain the event
- Multiple plausible alternatives = weakens
- No alternatives = strengthens
5. PHARMACOLOGIC PLAUSIBILITY
- Known drug effect?
- Mechanism plausible?
- Known for drug class?
- Consistent with mechanism of action?
5.3 Application Examples
Example 1: Probable Causality
- Strong temporal relationship
- Pharmacologically plausible
- Minimal alternatives
- No dechallenge data
- Result: PROBABLE
Example 2: Possible Causality
- Temporal relationship exists
- Alternative explanations also exist
- Cannot exclude drug
- Result: POSSIBLE (meets AR threshold)
Example 3: Unlikely Causality
- Alternative explanation more likely
- Weak temporal relationship
- Not pharmacologically plausible
- Result: UNLIKELY (not AR)
SECTION 6: EXPECTEDNESS DETERMINATION
6.1 The Investigator's Brochure (IB) as Reference
What is Expectedness? Event that is consistent with the IB = EXPECTED Event that differs from IB = UNEXPECTED
Three Components to Check:
- Event TYPE (is it listed?)
- Event SEVERITY (does it match description?)
- Event FREQUENCY (does rate match?)
6.2 Expectedness Scenarios
Scenario A: Type, Severity, Frequency ALL Match IB
- Result: EXPECTED
Scenario B: Type Listed, but Severity EXCEEDS IB
- Example: Rash listed as mild-moderate; patient has severe blistering
- Result: UNEXPECTED
Scenario C: Type Listed, Frequency EXCEEDS IB Substantially
- Example: IB lists event at 2%; study shows 15%
- Result: UNEXPECTED
Scenario D: Event Type NOT Listed Anywhere
- Result: AUTOMATICALLY UNEXPECTED
6.3 Critical Point: IB Versioning
Use IB version IN EFFECT AT TIME OF EVENT
- Not post-event IB updates
- Not future IB versions
- Not retrospective reclassifications
