Phase 3 trial of NTLA-2002 gene-editing therapy for HAE slated for 2024

Section 3 trial of NTLA-2002 gene-editing remedy for HAE slated for 2024

Enrollment for the Section 2 portion of a scientific trial testing NTLA-2002, Intellia Therapeutics’ experimental gene-editing remedy for hereditary angioedema (HAE), is predicted to be accomplished this 12 months.
