Frequently Asked Questions
What is ALCOA+?
ALCOA+ is a data integrity framework for regulated GxP environments. The acronym defines data as Attributable, Legible, Contemporaneous, Original, and Accurate. The “+” adds the attributes of Complete, Consistent, Enduring, and Available.
Why is this framework applied to AAV and Lentivirus programs?
Regulatory bodies like the FDA and EMA require verifiable data to support product quality and safety claims for viral vector programs. The ALCOA+ framework provides the structure for a defensible data package, from plasmid sourcing to final analytics, for IND and IMPD submissions.
When should our team implement ALCOA+ principles?
These data integrity practices should be integrated into all aspects of program development.
How does ALCOA+ relate to plasmid starting materials?
Viral vector quality is directly linked to the quality of the input plasmid DNA. ALCOA+ principles ensure all documentation for plasmid manufacturing, characterization, and release testing is traceable and accurate, creating a coherent CMC narrative.
Robust data integrity underpins every successful regulatory submission for advanced therapeutics and complex biologics. For teams developing AAV, lentiviral, or adenovviral vectors, the ALCOA+ framework provides the necessary structure for a defensible data package. Applying proven intelligence in CMC documentation is a direct method for accelerating regulatory readiness and minimizing clinical risk.
This systematic approach helps ensure that all data generated during process development, manufacturing, and analytical testing is verifiable and can withstand regulatory scrutiny. Each component of ALCOA+ addresses a potential point of failure in the data lifecycle.
