Compassionate use, also known as expanded access, refers to the provision of investigational drugs or therapies to patients with serious or life-threatening conditions who have exhausted approved treatment options and do not qualify for clinical trials. This practice is crucial in giving hope to patients who have no other therapeutic alternatives.
Historical Context
The concept of compassionate use has evolved significantly over the decades, primarily in response to advocacy from patient groups and the need for more humane healthcare policies. Notable milestones include:
- 1962 Kefauver Harris Amendment: Strengthened drug regulation in the United States.
- 1987 FDA Expanded Access Programs: Formalized access to experimental therapies for AIDS patients.
- Right to Try Act of 2018: Expanded the rights of terminally ill patients to access investigational drugs.
Types/Categories
Compassionate use can be classified into several categories:
- Individual Patient INDs (Investigational New Drug Applications): For single patients.
- Intermediate-size Patient Populations: For groups of patients with similar conditions.
- Widespread Treatment Use: For larger groups under expanded access programs.
Key Events
- Thalidomide Crisis (1960s): Highlighted the need for drug safety and strict regulations.
- AIDS Epidemic (1980s): Led to significant changes in access to experimental treatments.
- COVID-19 Pandemic (2020s): Accelerated emergency use authorizations for vaccines and treatments.
Detailed Explanations
Compassionate use involves a careful assessment by regulatory authorities, such as the FDA, to ensure that the potential benefits outweigh the risks. The process typically includes:
- Request Submission: A physician submits a request on behalf of a patient.
- Ethics Review: An institutional review board (IRB) reviews the case.
- Regulatory Approval: Authorities approve the use under specific conditions.
- Patient Consent: Informed consent from the patient or legal representative is mandatory.
Mathematical Formulas/Models
While compassionate use is more about ethical considerations than mathematical models, probability and risk-benefit analyses are crucial. A simplified risk-benefit ratio can be modeled as:

Importance and Applicability
Compassionate use is vital in providing potentially life-saving treatments to those in dire need. It applies particularly to:
- Rare diseases with no approved treatments.
- Terminal illnesses where standard therapies have failed.
- Rapidly evolving conditions like emerging infectious diseases.
Examples
- Ebola Virus: The use of experimental drugs during outbreaks.
- Amyotrophic Lateral Sclerosis (ALS): Access to investigational therapies.
- Cancer: Experimental oncology drugs in late-stage patients.
Considerations
- Ethical Issues: Balancing hope and false promise.
- Legal Framework: Adhering to regulatory guidelines.
- Financial Aspects: High costs of investigational treatments.
Related Terms
- Clinical Trials: Research studies to test new treatments.
- Emergency Use Authorization (EUA): Temporary approval of unapproved drugs during emergencies.
- Orphan Drugs: Treatments for rare diseases.
Comparisons
- Compassionate Use vs. Clinical Trials: Compassionate use is for patients ineligible for trials, often with immediate need, whereas clinical trials are systematic studies to gather data.
- Compassionate Use vs. Right to Try: Right to Try laws bypass some FDA oversight for terminally ill patients seeking investigational drugs.
Interesting Facts
- Famous Cases: Public figures, such as AIDS activist Ryan White, have historically shaped compassionate use policies.
- Global Variations: Different countries have unique approaches and regulations.
Inspirational Stories
- Abigail Burroughs: Fought for access to experimental cancer drugs, leading to reforms in compassionate use policies.
Famous Quotes
- “To cure sometimes, to relieve often, to comfort always.” – Hippocrates
Proverbs and Clichés
- “Where there’s life, there’s hope.”
Expressions
- Life-saving last resort: Describes treatments given when all other options have failed.
Jargon and Slang
- Expanded Access: Another term for compassionate use.
- Right to Try: Legal right to access experimental treatments without complete regulatory approval.

Final Summary
Compassionate use plays a critical role in modern medicine, offering a lifeline to patients with no other options. By balancing ethical considerations, regulatory guidelines, and patient needs, compassionate use allows access to potentially life-saving treatments when conventional therapies are not viable. The practice underscores the importance of patient advocacy and continuous evolution of healthcare policies to address emerging medical challenges.
