EAP vs. EUA
EAP: Sometimes called compassionate use, expanded access is a potential pathway for a patient with an immediately life-threatening condition or serious disease or condition to gain access to an investigational medical product (drug, biologic, or medical device) for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available.
EUA: Under section 564 of the Federal Food, Drug, and Cosmetic Act (FD&C Act), the FDA Commissioner may allow unapproved medical products or unapproved uses of approved medical products to be used in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions caused by CBRN threat agents when there are no adequate, approved, and available alternatives.
EAP IRB approval: A bunch of accredited Dr's reviewed info and say it will benefit more than it will hurt. Dr's must fill out a form and have drug shipped. No media coverage.
EUA FDA approval: A bunch of accredited Dr's reviewed info and efficacy results, say it will benefit more than it will hurt. Drug is on the shelf in hospital. Lots of media coverage.
