Expanded Access — What It Means in Clinical Trials
Plain English Definition
Expanded access (sometimes called "compassionate use") allows patients with serious or life-threatening conditions to use an experimental treatment outside of a clinical trial, usually when no other options are available. The drug has not been approved yet but has shown enough promise that regulators allow it on a case-by-case basis.
Why It Matters
If you have exhausted all approved treatments, expanded access may be an option. Your doctor would need to apply on your behalf, and the drug company must agree to provide the treatment.
Example
A listing might say: "Expanded access program for Drug Z in patients with treatment-resistant condition." This is not a standard trial — it is early access to a promising drug.
