Expanded access
Program providing access to unapproved drugs or medical devices

Expanded access or compassionate use is the use of an unapproved drug or medical device under special forms of investigational new drug applications (IND) or IDE application for devices, outside of a clinical trial, by people with serious or life-threatening conditions who do not meet the enrollment criteria for the clinical trial in progress.
“Expanded access” enters the record as program providing access to unapproved drugs or medical devices. Crown Archives preserves that source wording while asking what Expanded, access and Program can confirm, complicate or overturn.
Why this record matters
“Expanded access” is worth following because a concise public description often conceals a longer documentary argument. Here, Expanded, access and Program provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 22, 2026.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
