STAT+: In a first for genome editing, Intellia Therapeutics reports positive early data on in vivo CRISPR therapy
In a major milestone for the still-young field of genome editing, Intellia Therapeutics said Saturday that the first six patients to receive a CRISPR-based treatment for a genetic nerve disorder have safely had the DNA inside their liver cells edited.
Preliminary results from the study — the first to show that CRISPR-based gene editing can be delivered systemically and performed in vivo, or inside the body — found that the treatment reduced levels of a disease-causing protein by an average of 87% in the higher dose cohort with only mild side effects. The encouraging interim Phase 1 results, presented at a conference on Saturday, were published simultaneously in the New England Journal of Medicine.
