Definition and Overview

Compassionate Use, also known as Expanded Access, refers to the provision of investigational medical products (drugs, biologics, or devices) to patients with serious or life-threatening conditions who lack alternative treatment options and are ineligible for clinical trials. Regulatory agencies such as the FDA (United States) and EMA (Europe) oversee compassionate use programs to ensure patient safety while granting access outside standard approval processes.

Analogy: The Lifeboat Principle

Imagine a shipwreck where lifeboats represent approved treatments. Most passengers (patients) board lifeboats, but some are stranded with no available seats—these are patients for whom standard therapies have failed or do not exist. Compassionate use acts as a rescue helicopter, offering a chance of survival by providing access to experimental therapies not yet available to the public.

Real-World Example

A patient with advanced amyotrophic lateral sclerosis (ALS) has exhausted all approved therapies. A new drug is in Phase II clinical trials, showing promise but not yet approved. Through compassionate use, the patient may receive the investigational drug, potentially improving quality of life or extending survival.

Regulatory Framework

  • United States (FDA): Physicians submit a request (Form FDA 3926) for single-patient access or larger group programs. The FDA reviews safety data and the manufacturer’s willingness to provide the drug.
  • European Union (EMA): National authorities manage requests, focusing on unmet medical needs and risk-benefit analysis.
  • Key Requirements:
    • Patient has a serious or life-threatening condition.
    • No comparable or satisfactory alternative therapy exists.
    • Potential benefit justifies potential risks.
    • Manufacturer agrees to provide the product.

Case Studies

1. Zolgensma for Spinal Muscular Atrophy (SMA)

Before FDA approval in 2019, Zolgensma, a gene therapy for SMA, was accessed by several children through compassionate use. Families petitioned the manufacturer and regulatory bodies, citing the rapid progression and fatality of SMA Type 1. The program provided critical data on safety and efficacy, influencing the approval process.

2. Remdesivir during COVID-19

During the early months of the COVID-19 pandemic, remdesivir was supplied to severely ill patients under compassionate use before formal emergency use authorization. A 2020 study published in The New England Journal of Medicine (“Compassionate Use of Remdesivir for Patients with Severe Covid-19,” Grein et al., 2020) reported clinical improvement in 68% of treated patients, supporting broader access.

3. CAR-T Cell Therapy for Leukemia

CAR-T cell therapies, such as tisagenlecleucel, were provided to pediatric leukemia patients who had relapsed after standard treatments. Compassionate use enabled access before FDA approval, saving lives and generating real-world evidence.

Famous Scientist Highlight: Dr. Janet Woodcock

Dr. Janet Woodcock, former Director of the FDA’s Center for Drug Evaluation and Research, has been instrumental in shaping expanded access policies. Her advocacy for patient-centered approaches led to streamlined application processes and increased transparency, making compassionate use more accessible.

Relation to Health

Compassionate use directly impacts health by:

  • Providing Hope: Offers last-resort options for patients with terminal or rare diseases.
  • Accelerating Data Collection: Real-world evidence from compassionate use can inform safety and efficacy, sometimes expediting drug approval.
  • Ethical Considerations: Balances patient autonomy and safety, raising questions about informed consent, access equity, and resource allocation.

Common Misconceptions

1. Compassionate Use Guarantees a Cure

Fact: Compassionate use does not ensure effectiveness. Investigational products may not help and could cause harm due to limited safety data.

2. Any Patient Can Access Investigational Drugs

Fact: Access is restricted to those with serious conditions and no alternatives. Regulatory approval and manufacturer consent are required.

3. Compassionate Use Bypasses Clinical Trials

Fact: It supplements, not replaces, clinical research. Data from compassionate use may support, but not substitute, rigorous trials.

4. Manufacturers Must Provide the Drug

Fact: Manufacturers are not obligated to supply investigational products. Production limitations, liability concerns, and ongoing trials may restrict availability.

Recent Research and Developments

A 2022 study in JAMA Network Open (“Expanded Access to Investigational Drugs for Patients With Rare Diseases: Trends and Challenges,” Lee et al., 2022) analyzed trends in compassionate use requests. Findings highlighted increased demand for access to rare disease therapies and underscored the importance of transparent criteria and patient advocacy.

Ethical and Social Implications

  • Patient Autonomy: Patients and families often advocate for access, sometimes using social media campaigns to pressure manufacturers.
  • Equity: Disparities exist in access based on geography, socioeconomic status, and disease awareness.
  • Risk-Benefit Analysis: Physicians and regulators must weigh potential benefits against unknown risks, especially in vulnerable populations.
