Intellia Reports Positive Data on Gene Therapy
Intellia Therapeutics says new data from the ongoing Phase 1/2 study of NTLA-2002 in patients with hereditary angioedema (HAE) suggest the CRISPR-based gene editing therapy has the potential to eliminate HAE attacks following a one-time infusion. Results were published online 10/24 in The New England Journal of Medicine. Based on the results, the company says it is progressing to a planned pivotal Phase 3 (HAELO) study.
“The Phase 2 data demonstrated that a majority of patients in the 50 mg arm experienced a complete response — no attacks at all and no further treatment needed — after a one-time infusion of NTLA-2002 through the latest follow-up, consistent with the long-term Phase 1 data,” the company says. It adds that approved HAE therapies can reduce but frequently do not eliminate all angioedema attacks and require chronic administration.
Intellia says that during the study NTLA-2002 was well tolerated. The most frequent adverse events were headache, fatigue and nasopharyngitis, it says, adding that no clinically significant laboratory abnormalities were observed.
