FDA May Decline Covid-19 EUA Requests
FDA has updated its guidance on Emergency Use Authorization (EUA) for Vaccines to Prevent Covid-19 to include a new section that says the agency may decline to review and process further EUA requests other than those for vaccines whose developers have already engaged with the agency. “Additionally, given the need to address urgent public health priorities, FDA may need to further prioritize among the EUA requests it receives for Covid-19 vaccine candidates,” it says.
Presumably, the agency move is acknowledging that its limited resources have been stretched and should be focused on current and viable EUA candidates. “When FDA assesses investigational Covid-19 vaccines for use under EUA, FDA’s review includes: stringent evaluation of product quality, including a determination that the facilities producing the product meet appropriate standards; evaluation of the conduct of clinical trials; and assessment of trial data integrity,” the guidance says. “FDA intends to decline to review and process EUA requests in cases where it is not feasible for the agency to verify any one of these characteristics.”
FDA insists that early interaction with the agency is critical, and Covid-19 vaccine developers should have the benefit of FDA feedback early and throughout the development process. “Therefore, their EUA requests are more likely to contain the comprehensive data and information needed to demonstrate that issuance of an EUA is appropriate, and the agency is more likely to be able to confirm the validity of the clinical and manufacturing information submitted in the EUA request,” the guidance adds.
