A lackluster efficacy signal has prompted Editas Medicine Inc. to pause enrollment in a phase I/II trial of its CRISPR/Cas9-based gene editing therapy, EDIT-101, which is in development for patients with a particular form of Leber congenital amaurosis type 10.
Proqr Therapeutics NV stock lost three-quarters of its value as word got out that its pivotal phase II/III study of sepofarsen in treating a tough, rare and genetic retinal disease failed to hit the primary endpoint.
