Allergan and Editas Medicine Announce Initial Data from Natural History Study to Evaluate Patients with Leber Congenital Amaurosis 10 (LCA10)

DUBLIN, Ireland and CAMBRIDGE, Mass., April 29, 2019 (GLOBE NEWSWIRE) -- Allergan plc (NYSE: AGN), a leading global pharmaceutical company, and Editas Medicine, Inc. (Nasdaq: EDIT), a leading genome editing company, announced initial data from the ongoing natural history study to evaluate patients with Leber congenital amaurosis 10 (LCA10), a rare form of blindness caused by mutations in the CEP290 gene. The Companies reported these data on Friday, April 26, in an oral presentation at the 6th Annual Retinal Cell and Gene Therapy (RCGT) Innovation Summit in Vancouver.

The Companies initiated the natural history study to prospectively evaluate and confirm the course of disease in patients and determine the reproducibility and stability of ophthalmic assessments over time. This knowledge has informed the planned Phase 1/2 interventional clinical trial design for AGN-151587 (EDIT-101), an experimental CRISPR genome editing medicine being investigated for the treatment of LCA10. Massachusetts Eye and Ear, an international center for treatment and research and a teaching hospital of Harvard Medical School, is one of seven sites enrolling patients in this natural history study.

“Better understanding the course of disease for patients with CEP290-associated retinal degeneration is a key step towards the interventional clinical trial for a CRISPR-based experimental medicine to treat this disease,” said Eric A. Pierce, M.D., Ph.D., Director of the Ocular Genomics Institute and William F. Chatlos Professor of Ophthalmology at Massachusetts Eye and Ear and Harvard Medical School, and Principal Investigator for the natural history study. “We are pleased to be working at the forefront of this research with Allergan and Editas Medicine and look forward to testing genome editing for the treatment of CEP290-associated retinal disease in the interventional trial.”

Twenty-one patients with LCA10-IVS26 mutations in CEP290 were included in this analysis of baseline characteristics and key clinical assessments, including visual acuity and full-field threshold sensitivity changes. Initial data from the natural history study suggest multiple clinical assessments should prove informative in the planned Phase 1/2 interventional trial.

AGN-151587 is set to be the first in vivo, or inside the body, CRISPR-based medicine administered to people anywhere in the world. In the planned Phase 1/2 clinical trial, Allergan and Editas Medicine intend to initiate patient screening mid-year and begin patient dosing in the second half of 2019, enrolling 10-20 patients in the U.S. and Europe.

About AGN-151587 (EDIT-101)
AGN-151587 (EDIT-101) is a CRISPR-based experimental medicine under investigation for the treatment of Leber congenital amaurosis 10 (LCA10). AGN-151587 is administered via a subretinal injection to reach and deliver the gene editing machinery directly to photoreceptor cells.

About Leber Congenital Amaurosis
Leber congenital amaurosis, or LCA, is a group of inherited retinal degenerative disorders caused by mutations in at least 18 different genes. It is the most common cause of inherited childhood blindness, with an incidence of two to three per 100,000 live births worldwide. Symptoms of LCA appear within the first years of life, resulting in significant vision loss and potentially blindness. The most common form of the disease, LCA10, is a monogenic disorder caused by mutations in the CEP290 gene and is the cause of disease in approximately 20‑30 percent of all LCA patients.

About the Editas Medicine-Allergan Alliance
In March 2017, Editas Medicine and Allergan Pharmaceuticals International Limited (Allergan) entered a strategic alliance and option agreement under which Allergan received exclusive access and the option to license up to five of Editas Medicine’s genome editing programs for ocular diseases, including AGN-151587 (EDIT-101). Under the terms of the agreement, Allergan is responsible for development and commercialization of optioned products, subject to Editas Medicine’s option to co-develop and share equally in the profits and losses of two optioned products in the United States. In August 2018, Allergan exercised its option to develop and commercialize AGN-151587 globally for the treatment of LCA10. Additionally, Editas Medicine exercised its option to co-develop and share equally in the profits and losses from AGN-151587 in the United States. Editas Medicine is also eligible to receive development and commercial milestones, as well as royalty payments on a per-program basis. The agreement covers a range of first-in-class ocular programs targeting serious, vision-threatening diseases based on Editas Medicine’s unparalleled CRISPR genome editing platform, including CRISPR/Cas9 and CRISPR/Cpf1 (also known as Cas12a).
