Invivyd Advocates for Monoclonal Antibodies in COVID-19 Strategies
Revamping COVID-19 Prevention Strategies
WALTHAM, Mass. — Invivyd, Inc. (Nasdaq: IVVD) has recently taken a significant step by filing a Citizen Petition with the U.S. Food and Drug Administration (FDA). This petition is a call for the agency to shift its approach regarding the development of vaccines and monoclonal antibodies (mAbs) aimed at preventing COVID-19. The goal is to restore public trust in the efficacy of these medical interventions as Americans navigate a future where COVID-19 and other viral diseases remain prevalent.
Understanding the Evolving Virus Landscape
The COVID-19 pandemic has transformed both the virus and the world's approach to handling it. Initially in 2020, the entire population was considered immunologically naive, lacking prior exposure to SARS-CoV-2. However, as time has passed, a significant number of Americans have developed some level of immunologic memory due to vaccinations or infections caused by circulating variants.
The Shift in COVID-19 Variants
From its original emergence in Wuhan, SARS-CoV-2 has undergone numerous mutations, evolving from variants that were primarily vulnerable to immune responses to those that exhibit considerable resistance to it. These changes highlight a pressing concern where the effectiveness of vaccines against variants like Omicron, which have become more prevalent, appears substantially diminished compared to their performance against earlier strains.
Need for Long-term Evaluation of Vaccines
Further insights into the dynamics behind the waning efficacy of vaccines over time have become clearer. This understanding suggests that instead of short-term clinical trials, there's a pressing need for long-term evaluations to provide reliable data on vaccine performance.
Contrastingly, Invivyd's recent studies on monoclonal antibodies have shown promising results. They have implemented rigorous placebo-controlled trials that explore safety, antiviral actions, and overall efficacy in populations that are seropositive against contemporary and evasive variants of the virus over extended durations.
A Path Forward for COVID-19 Prevention
With the findings from these studies, Invivyd urges the FDA to reassess the current methodologies in evaluating mRNA vaccine effectiveness. The suggestion includes conducting randomized, placebo-controlled trials featuring modern populations that have significant prior exposure to the virus, both from infections and vaccinations, to yield more accurate insights into vaccine efficacy.
Additionally, Invivyd advocates for the FDA to acknowledge serum virus neutralizing antibody (sVNA) titers as a suitable basis for Biologics License Application (BLA) approvals. This would ensure that approvals are grounded in data indicating true clinical benefit as new variants arise.
