In almost five decades of FDA experience, this is the first time I have ever seen a Emergency Use Authorization (EUA) put into practice — but, in real terms, what is a “EUA,” and why it is used so infrequently? The Emergency Use Authorization (EUA) authority permits FDA to help fortify the country’s public health protections against CBRN dangers by encouraging the accessibility and utilization of MCMs required during public health crises.
Under segment 564 of the Federal Food, Drug, and Cosmetic Act he FDA Commissioner may permit unapproved medical products or unapproved employments of endorsed medical products to be utilized in a crisis to analyze, treat, or forestall genuine or hazardous sicknesses or conditions brought about by CBRN (concoction, natural, radio logical, and atomic) danger operators when there are no satisfactory, affirmed, and accessible other options.

The U.S. EUA, Emergency Use Authorization Act, will be lifted, the medical device industry returns to the real world, and the FDA recovers control of the clinical endorsement measure with a genuine device audit set up.
The FDA’s position underpins the crisis readiness and reaction and cultivates the turn of events and accessibility of clinical items for use in the crises. These medical products, additionally alluded to as clinical countermeasures or MCMs, incorporate medications (e.g., antiviral and counteract ants), organic items (e.g., immunizations, blood items, and natural therapeutics), and gadgets (e.g., in vitro diagnostics and PPE).
Before the FDA may issue a EUA, the HHS Secretary must declare circumstances that exist to justify the authorization of the EUA and include the following actions:
- A determination by the Secretary of Homeland Security that there is a domestic emergency, or a significant potential for a domestic emergency, involving a heightened risk of attack with a CBRN agent(s);
- A determination by the Secretary of HHS that there is a public health emergency, or a significant potential for a public health emergency, that affects, or has a significant potential to affect the national security or the health and security of United States citizens living abroad, and that involves a CBRN agent or agents, or a disease or condition that may be attributable to such agent(s).
After the Secretary of HHS gives an EUA statement, in view of one of these two judgments, and in the wake of counseling (to the degree attainable and proper given the pertinent conditions) with the Assistant Secretary for Preparedness and Response (ASPR), the Director of the National Institutes of Health (NIH), and the Director of CDC, the Commissioner may approve the crisis utilization of an unapproved item or an unapproved utilization of an endorsed item, given that other legal standards are met.
EUA applicant products incorporate medical products and utilizations that are not endorsed, cleared, or authorized under areas 505, 510(k), and 515 of the FD&C Act or segment 351 of the PHS Act. After the requisite determination and declaration have been issued subsequent to feasible and appropriate consultations, FDA may issue a EUA only if the FDA concludes that the following four statutory criteria for issuance have been met.
If the product does not meet the statutory criteria for issuance or is not otherwise an appropriate candidate, an alternative regulatory mechanism (i.e., access under an IND or IDE, which can include expanded access protocols) may be an appropriate means to provide patients access to an unapproved use of a product in a CBRN emergency.
- Serious or Life-Threatening Disease or Condition
- Evidence of Effectiveness
- Risk-Benefit Analysis
- No Alternatives
- Serious or Life-Threatening Disease or Condition:
For the FDA to issue a EUA, the CBRN agent(s) referred to in the HHS Secretary’s EUA declaration must be capable of causing a serious or life-threatening disease or condition.
- Evidence of Effectiveness:
The “may be effective” standard for EUAs provides for a lower level of evidence than the “effectiveness” standard that the FDA uses for product approvals. The FDA intends to assess the potential effectiveness of a possible EUA product on a case-by-case basis using a risk-benefit analysis, as explained below.
- Risk-Benefit Analysis
In determining whether the known and potential benefits of the product outweigh the known and potential risks, the FDA intends to look at the totality of the scientific evidence to make an overall risk-benefit determination. Such evidence, which could arise from a variety of sources, may include (but is not limited to): results of domestic and foreign clinical trials, in vivo efficacy data from animal models, and in vitro data, available for FDA consideration.
- No Alternatives
For the FDA to issue a EUA there must be no adequate, approved, and available alternative to the candidate product for diagnosing, preventing, or treating the disease or condition. A potential alternative product may be considered “unavailable” if there are insufficient supplies of the approved alternative to fully meet the emergency need.
Be assured that the EUA conclusion will come as a big surprise for many of the companies that have been exporting under this temporary status. The bigger surprise may come if the FDA conducts its own testing and, as a result, requests that non compliant products to be recalled. Getting things back to normal for the FDA premarket review is a necessity. The public needs the assurance that the devices and drugs they are using are safe and effective. But, how does the FDA ever balance the increasing supply demands with the required device and drug quality
