Key points
- Analyzed IND submissions to the FDA spanning 1995 to 2025
- Authored by researchers from the Center for Biologics Evaluation and Research
- Identified common reasons for regulatory holds in AAV development
An evaluation of Investigational New Drug applications submitted to the US Food and Drug Administration between 1995 and 2025 details significant expansion in the development of adeno-associated virus vectors over a thirty-year span. Conducted by researchers from the agency's Center for Biologics Evaluation and Research and published in Nature Biotechnology, the review outlines the trajectory of these advanced therapeutic candidates and identifies recurring factors that prompt regulatory holds during the application process.
The findings offer a retrospective look at how vector-based applications have evolved, highlighting common hurdles that developers encounter when navigating clinical trial authorizations. While the report outlines widespread developmental trends within the regulatory pipeline, it remains an observational summary of past submissions rather than a step-by-step guideline for future clinical trial approvals.
What to know: Reviewing historical regulatory data helps developers anticipate agency feedback, but each therapeutic candidate undergoes distinct evaluation based on its individual preclinical profile. Readers considering participation in clinical trials or seeking information on emerging treatments should consult qualified medical professionals.
