Revance BLA Final Review Action Deferred Due to Covid
FDA has deferred its review decision on a Revance Therapeutics BLA for daxibotulinumtoxinA for injection, an investigational neuromodulator for treating moderate to severe glabellar (frown) lines. The agency said a required inspection could not be conducted at the company’s northern California manufacturing facility due travel restrictions associated with the Covid-19 pandemic. Revance says it confirmed with FDA that their communication was not a complete response letter. “Though the company’s BLA is still under review, the FDA did not indicate there are any other review issues at this time, beyond the on-site inspection,” it says. “The FDA stated they are actively working to define an approach for scheduling outstanding inspections, once safe travel may resume and based on public health need and other factors.” Revance describes daxibotulinumtoxinA as a proprietary stabilizing peptide excipient combined with a highly purified botulinum toxin that does not contain human or animal-based components.
