Informed Consent Form — Clinical Trial

Produces a plain-language ICF (≤ 8th-grade reading level) covering all 21 CFR 50.25 required elements, HIPAA authorization, and ethics-compliant framing for research subjects.

Prerequisites

Collect before drafting:

  1. Protocol details — title, protocol number, phase, sponsor, IND number
  2. Investigational product — name, mechanism, dosing, route, known risk profile
  3. Study design — randomization, arms (incl. placebo), visit schedule, duration
  4. Site info — PI name/title, institution, IRB name and contact
  5. Risk/benefit data — preclinical and prior clinical risk frequencies/severities
  6. Injury/compensation policy — sponsor coverage for research-related injury; participation payments

Output Structure

1. Header Block

On every page: protocol title, protocol number, version/date, page X of Y.

2. Study Information

Purpose

  • Plain-language disease/condition description
  • What the study tests; trial phase; subject count (site and total)
  • Include: "This is a research study, not standard medical treatment."

Procedures (chronological)

  • Screening, randomization (arm probabilities incl. placebo), visit-by-visit table:
VisitTimingDurationProcedures
ScreeningWeek −2~2 hrsLabs, exam, eligibility
BaselineDay 1~3 hrsIP administration, vitals, ECG
Follow-upWk 4, 8, 12~1 hrLabs, safety assessments
End of StudyWeek 16~2 hrsFinal assessments, unblinding
  • Flag research-only vs. standard-of-care procedures
  • Note preparation requirements (fasting, hold meds)

Risks and Discomforts

Organize by category with frequency and severity:

CategoryExampleFrequencySeverity
Investigational productNausea, hepatotoxicityCommon/RareMild/Serious
Study proceduresVenipuncture bruisingCommonMild
Placebo exposureForgoing active therapyN/AStudy-specific
ReproductiveTeratogenicityUnknownPotentially serious
Privacy/psychosocialTime burden, incidental findingsLowMild
  • Include unknown-risks disclosure and new-information notification statement
  • State injury care/compensation available and what is not covered

Potential Benefits

  • Direct benefit: state honestly if possible, probable, or not expected; cite prior data; note not guaranteed
  • Societal benefit: knowledge advancement
  • Payments/free medication: list but clarify these are not medical benefits
  • Include: "Not participating will not affect your access to standard medical care."

3. Subject Rights

Confidentiality

  • Coded identifiers, encrypted storage, limited access
  • Authorized accessors: research team, IRB, FDA, sponsor/monitors, DSMB
  • Mandatory disclosure circumstances (reporting obligations, court order)
  • Publication: no individual identification; data retention period stated
  • HIPAA Authorization (if applicable): PHI use/disclosure scope; required for participation

Voluntary Participation and Withdrawal

  • Voluntary; refusal/withdrawal does not affect care or benefits
  • Withdraw any time without penalty; contact PI at listed number
  • Pre-withdrawal data may be retained; investigator/sponsor may remove subject for safety, non-compliance, or study termination
  • New findings affecting willingness will be communicated

Contacts

RoleNamePhoneHours
PI (questions, injuries)[Name, MD][###-###-####]24/7 emergencies
IRB (rights concerns)[IRB Name][###-###-####]M–F 9–5
After-hours emergency[On-call][###-###-####]Evenings/weekends

4. Consent Statement

First-person acknowledgment covering: form read/explained, questions answered, voluntary participation, right to withdraw, agreement to participate in [Study Title], Protocol [Number].

Optional check-box consents (if applicable):

  • Future biospecimen research use
  • Genetic testing
  • Long-term follow-up contact
  • HIPAA authorization

5. Signature Block (per 21 CFR 50.27)

SignatoryPrinted NameSignatureDate
Research Subject
Legally Authorized Representative
Representative's relationship/authorityN/AN/A
Impartial Witness (if subject cannot read)
Person Obtaining Consent (name + role)
  • Subject receives signed, dated copy
  • Add re-consent rows if protocol requires re-consent at defined intervals

Drafting Rules

  • Reading level: ≤ 8th grade; define technical terms on first use
  • No exculpatory language: No waiver of legal rights or liability release (21 CFR 50.25(a)(8))
  • Therapeutic misconception: Distinguish research from treatment; do not overstate direct benefit
  • Placebo disclosure: Explain probability and risk of forgoing active therapy
  • Vulnerable populations: Add protections per 21 CFR 50 Subparts C, D (pregnant women, children, prisoners, cognitively impaired)
  • Formatting: ≥ 12pt font, section headings, page numbers, version/date footer; typical 8–15 pages

Checklist Before Finalizing

  • All 21 CFR 50.25(a) basic elements present
  • All applicable 50.25(b) additional elements included
  • No exculpatory language
  • HIPAA authorization section included (if applicable)
  • Vulnerable-population protections added (if applicable)
  • Reading level verified ≤ 8th grade
  • IRB approval required before use; retain IRB-stamped version as operative document
  • [VERIFY]: Confirm ICH E6(R3) GCP requirements align with jurisdiction's adoption status
