Is it true that igG-cleaving endopeptidases can degrade anti-AAV neutralizing antibodies and enable successful gene therapy in seropositive patients?

Uncertain updated weekly · as of

Priors rates this Uncertain — 59 out of 100, updated weekly. It is genuinely uncertain. On the claim that igG-cleaving endopeptidases can degrade anti-AAV neutralizing antibodies and enable successful gene therapy in seropositive patients, its four-agent AI review panel weighs 5 primary peer-reviewed studies.

where this sits on Priors’ scale of how settled the evidence is

How we got this answer. Priors runs each claim through a panel of four AI agents, each acting as a specialist expert reviewer. They read the published, peer-reviewed studies behind the question, judge how strong, consistent and reliable the evidence is, and turn that judgment into a single rating from 0 to 100 — refreshed every week as new studies appear, so it reflects where the evidence stands today, not a one-off verdict.

The traceable studies behind this rating — and the panel’s single strongest counter-argument to it — are in Priors’ full Gene Therapy Neuromuscular Disease review.
