The U.S. FDA’s January 2025 draft guidance for test validation in public health emergencies drew only six responses, but pointed responses they were, indeed. As an example, the Association for Molecular Pathology (AMP) said the draft’s recommendation for the use of 30 positive and 30 negative (30/30) samples for validation of lab-developed tests is likely to hamper test availability in an emergent situation, a time when samples are likely to be difficult to obtain.
About two months after Astrazeneca plc said its application for sipavibart (AZD-3152) had been accepted by the EMA for pre-exposure prophylaxis (PrEP) against COVID-19 in immunocompromised people, Invivyd Inc. unveiled positive 180-day exploratory efficacy data from the company’s ongoing Canopy phase III trial with Pemgarda (pemivibart) in the same indication – and made known less happy news from regulators on the other side of the pond.
The U.S. FDA issued a May 9 warning letter to Cue Health Inc., of San Diego, following what may have been a routine inspection, but the inspection disclosed that the company had made changes to a COVID test that was granted market access via the emergency use authorization program.
The U.S. FDA granted emergency use authorization (EUA) on March 22 for Waltham, Mass.-based Invivyd Inc.’s half-life extended monoclonal antibody (MAb) VYD-222 – making it available to prevent COVID-19 in immunocompromised adults and adolescents – but its use comes with a boxed warning for anaphylaxis.
Invivyd Inc.’s VYD-222 produced positive initial top-line results in the ongoing pivotal phase III Canopy study for preventing symptomatic COVID-19. The results could reach a vulnerable population of patients who are immunocompromised and don’t get the same protection as other patients, the company’s CEO, Dave Hering, told BioWorld.
With the public health emergency for the COVID-19 pandemic rapidly winding down, the U.S. FDA has published guidance for the transition of COVID-specific diagnostic tests and other articles to conventional premarket review mechanisms.
Citing clinical trial data backed by real-world data, members of the U.S. FDA’s Antimicrobial Drugs Advisory Committee voted overwhelmingly, 16-1, March 16 that the overall benefit-risk assessment is favorable for the use of Pfizer Inc.’s Paxlovid to treat mild to moderate COVID-19 in adults who are at high risk for progression to severe COVID-19, including hospitalization or death.
The FDA’s emergency use authorization (EUA) program for rapid antigen tests for the COVID-19 pandemic is coming to an end, but few rapid antigen test makers have laid out clear plans regarding the post-public health emergency world. Quidelortho Corp. managed to beat the competition to the non-EUA market for these tests with a grant of de novo petition for its Sofia rapid antigen test, which now provides other tests with a predicate device, thus ensuring that this will not be the last such test to reach the U.S. market.
Shares of Veru Inc. hit a 52-week low March 3 after the U.S. FDA declined to grant an emergency use authorization (EUA) for sabizabulin for use in hospitalized adults with moderate to severe COVID-19 who are at high risk for acute respiratory distress syndrome. The decision comes as little surprise, given the negative advisory panel vote in November, but the agency’s wording might suggest potential use for the microtubule disruptor in the future.
Strong data for pegylated interferon lambda, Eiger Biopharmaceuticals Inc.’s experimental COVID-19 treatment, boosted the company stock (NASDAQ:EIGR) 23% on Feb. 9 as the company continues to seek regulatory approval. That approval path is blocked as interferon lambda is not currently approved by the U.S. FDA for any use. In October, the company said it would not submit emergency authorization use request after feedback from the FDA.
