The second guidance provides the Agency’s current recommendations on phase 2 and phase 3 clicnial trials to establish safety and efficacy of therapeutic and prophylactic agents for COVID-19.
The guidance focuses on development of direct antiviral drugs or products with immunomodulatory activity and notes that the guidance does not apply to preventative vaccines or convalescent plasma.
Treatment trials: Essential clinical outcome measures
- Need for invasive mechanical ventilation
- Sustained clinical recovery
Prevention trials: Primary endpoint
- Occurrence of laboratory-confirmed SARS-CoV-2 infection or SARS-CoV-2 infection with symptoms within a prespecified timeframe.
“FDA anticipates this guidance will help sponsors to efficiently design studies that may lead to the review and potential approval of safe and effective drugs and biological products to address the COVID-19 pandemic,” states FDA's document.
The guidance provides specific recommendations for study population, trial design, efficacy endpoints, safety, and statistical considerations.
FDA says it “strongly recommends that drugs to treat or prevent COVID-19 be evaluated in randomized, placebo-controlled, double-blind clinical trials using a superiority design,” and that standard of care should be applied in all treatment arms.
“Sponsors should address anticipated off-label use of any other drugs, devices, or interventions that might be used to manage COVID-19,” FDA writes.
The new guidance follows the launch of FDA’s coronavirus treatment acceleration program (CTAP) in March and the National Institutes of Health’s (NIH) Accelerating Covid-19 Therapeutic Innovations and Vaccines (ACTIV) public-private partnership in April.
As of Monday, FDA said there are 144 active clinical trials of therapeutics for Covid-19 and that it is aware of more than 450 development programs that are still in planning stages.
