BACKGROUNDCEP290-associated inherited retinal degeneration causes severe early-onset vision loss due to pathogenic variants in CEP290. EDIT-101 is a clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9) gene-editing complex designed to treat inherited retinal degeneration caused by a specific damaging variant in intron 26 of CEP290 (IVS26 variant).METHODSWe performed a phase 1-2, open-label, single-ascending-dose study in which persons 3 years of age or older with CEP290-associated inherited retinal degeneration caused by a homozygous or compound heterozygous IVS26 variant received a subretinal injection of EDIT-101 in the worse (study) eye. The primary outcome was safety, which included adverse events and dose-limiting toxic effects. Key secondary efficacy outcomes were the change from baseline in the best corrected visual acuity, the retinal sensitivity detected with the use of full-field stimulus testing (FST), the score on the Ora-Visual Navigation Challenge mobility test, and the vision-related quality-of-life score on the National Eye Institute Visual Function Questionnaire-25 (in adults) or the Children's Visual Function Questionnaire (in children).RESULTSEDIT-101 was injected in 12 adults 17 to 63 years of age (median, 37 years) at a low dose (in 2 participants), an intermediate dose (in 5), or a high dose (in 5) and in 2 children 9 and 14 years of age at the intermediate dose. At baseline, the median best corrected visual acuity in the study eye was 2.4 log₁₀ of the minimum angle of resolution (range, 3.9 to 0.6). No serious adverse events related to the treatment or procedure and no dose-limiting toxic effects were recorded. Six participants had a meaningful improvement from baseline in cone-mediated vision as assessed with the use of FST, of whom 5 had improvement in at least one other key secondary outcome. Nine participants (64%) had a meaningful improvement from baseline in the best corrected visual acuity, the sensitivity to red light as measured with FST, or the score on the mobility test. Six participants had a meaningful improvement from baseline in the vision-related quality-of-life score.CONCLUSIONSThe safety profile and improvements in photoreceptor function after EDIT-101 treatment in this small phase 1-2 study support further research of in vivo CRISPR-Cas9 gene editing to treat inherited retinal degenerations due to the IVS26 variant of CEP290 and other genetic causes.

Inherited retinal degenerations (IRDs) are a leading cause of blindness. Although gene-supplementation therapies have been developed, they are only available for a small proportion of recessive IRD mutations. In contrast, genome editing using clustered-regularly interspaced short palindromic repeats (CRISPR) CRISPR-associated (Cas) systems could provide alternative therapeutic avenues for treating a wide range of genetic retinal diseases through targeted knockdown or correction of mutant alleles. Progress in this rapidly evolving field has been highlighted by recent Food and Drug Administration clinical trial approval for EDIT-101 (Editas Medicine, Inc., Cambridge, MA), which has demonstrated efficacious genome editing in a mouse model of CEP290-associated Leber congenital amaurosis and safety in nonhuman primates. Nonetheless, there remains a significant number of challenges to developing clinically viable retinal genome-editing therapies. In particular, IRD-causing mutations occur in more than 200 known genes, with considerable heterogeneity in mutation type and position within each gene. Additionally, there are remaining safety concerns over long-term expression of Cas9 in vivo. This review highlights (i) the technological advances in gene-editing technology, (ii) major safety concerns associated with retinal genome editing, and (iii) potential strategies for overcoming these challenges to develop clinical therapies.

Leber congenital amaurosis type 10 is a severe retinal dystrophy caused by mutations in the CEP290 gene^1,2. We developed EDIT-101, a candidate genome-editing therapeutic, to remove the aberrant splice donor created by the IVS26 mutation in the CEP290 gene and restore normal CEP290 expression. Key to this therapeutic, we identified a pair of Staphylococcus aureus Cas9 guide RNAs that were highly active and specific to the human CEP290 target sequence. In vitro experiments in human cells and retinal explants demonstrated the molecular mechanism of action and nuclease specificity. Subretinal delivery of EDIT-101 in humanized CEP290 mice showed rapid and sustained CEP290 gene editing. A comparable surrogate non-human primate (NHP) vector also achieved productive editing of the NHP CEP290 gene at levels that met the target therapeutic threshold, and demonstrated the ability of CRISPR/Cas9 to edit somatic primate cells in vivo. These results support further development of EDIT-101 for LCA10 and additional CRISPR-based medicines for other inherited retinal disorders.

Participants of pioneering CRISPR gene editing trial see vision improve

About 79% of clinical trial participants experienced measurable improvement after receiving experimental, CRISPR-based gene editing that is designed to fix a rare form of blindness, according to a new article. About 79% of clinical trial participants experienced measurable improvement after receiving experimental, CRISPR-based gene editing that is designed to fix a rare form of blindness, according to a paper published today in the New England Journal of Medicine. "This trial shows CRISPR gene editing has exciting potential to treat inherited retinal degeneration," said Mark Pennesi, M.D., Ph.D., a corresponding author on the paper, an ophthalmologist and Oregon Health & Science University's lead scientist for the Phase 1/2 BRILLIANCE trial. "There is nothing more rewarding to a physician than hearing a patient describe how their vision has improved after a treatment. One of our trial participants has shared several examples, including being able to find their phone after misplacing it and knowing that their coffee machine is working by seeing its small lights. "While these types of tasks might seem trivial to those who are normally sighted, such improvements can have a huge impact on quality of life for those with low vision." The BRILLIANCE trial evaluated the safety and effectiveness of EDIT-101, an experimental gene editing treatment developed by Editas Medicine that uses CRISPR technology. The experimental treatment was designed to edit a mutation in the CEP290 gene, which provides instructions to create a protein that is critical for sight. People with this gene mutation have a rare condition that is commonly called Leber Congenital Amaurosis, or LCA, Type 10, for which there is currently no Food and Drug Administration-approved treatment. LCA's various types occur in about 2 or 3 out of 100,000 newborns. The OHSU Casey Eye Institute treated the trial's first participant in early 2020. That procedure also marked the first time that CRISPR had been used to edit genes within the human body, called in vivo gene editing. The new paper describes the study's findings through February 2023 and details how the trial's 14 participants -- 12 adults and two children -- responded to receiving EDIT-101 in one eye. Key results include: Four specific outcomes were used to evaluate the experimental treatment's effectiveness: Further research for a future treatment In November 2022, trial sponsor Editas Medicine announced that it was pausing the trial's enrollment and would seek another partner to continue the experimental therapy's development. Pennesi and colleagues are exploring working with other commercial partners to conduct additional trials, in collaboration with Editas. The researchers hope future studies can examine ideal dosing, whether a treatment effect is more pronounced in certain age groups such as younger patients, and include refined endpoints to measure impacts on activities of daily living. "This research demonstrates that CRISPR gene therapy for inherited vision loss is worth continued pursuit in research and clinical trials," said Mass Eye & Ear ophthalmologist Eric Pierce, M.D., Ph.D., who is also a corresponding author. "While more research is needed to determine who may benefit most, we consider the early results promising. To hear from several participants how thrilled they were that they could finally see the food on their plates -- that is a big deal. These were individuals who could not read any lines on an eye chart and who had no treatment options, which is the unfortunate reality for most people with inherited retinal disorders." "Our patients are the first congenitally blind children to be treated with gene editing, which significantly improved their daytime vision," said the paper's third corresponding author, Tomas S. Aleman, M.D., a pediatric ophthalmologist at the Children's Hospital of Philadelphia and the University of Pennsylvania's Scheie Eye Institute. "Our hope is that the study will pave the road for treatments of younger children with similar conditions and further improvements in vision. This trial represents a landmark in the treatment of genetic disease, in specific genetic blindness, by offering important alternative treatment when traditional forms of therapy, such as gene augmentation, are not an option." "The results from the BRILLIANCE trial provide proof of concept and important learnings for the development of new and innovative medicines for inherited retinal diseases. We've demonstrated that we can safely deliver a CRISPR-based gene editing therapeutic to the retina and have clinically meaningful outcomes," said Editas Medicine Chief Medical Officer Baisong Mei, M.D., Ph.D. The OHSU Casey Eye Institute is one of five clinical sites that recruited participants for the trial. The other sites are: Bascom Palmer Eye Institute in Miami, Florida; Mass Eye and Ear in Boston, Massachusetts; Scheie Eye Institute at the University of Pennsylvania and Children's Hospital of Philadelphia; and Kellogg Eye Center in Ann Arbor, Michigan.

Editas grabs orphan drug status for sickle cell disease CRISPR therapy

Adam Zamecnik @a_zamecnik Image Credit: Shutterstock / Ezume Images The US Food and Drug Administration (FDA) has granted an Orphan Drug Designation to Editas Medicine’s gene therapy EDIT-301 in sickle cell disease, based on an April 27 announcement. The US agency previously granted the Orphan Drug Designation to EDIT-301 for its study in beta thalassemia, in May 2022. The company is studying EDT-301 in sickle cell disease in a Phase I/II RUBY study (NCT04853576), and is on track to provide a clinical update by mid-2023. Editas had previously announced positive safety and efficacy data with two patients enrolled in the RUBY study, stating that the therapy was well-tolerated and that both patients were successfully engrafted and free of vaso-occlusive events during the follow-up. The first patient had a total haemoglobin level of 16.4 g/dL and 45.4% fetal haemoglobin after five months, per a December 2022 update. Editas has plans to dose 20 patients on this study by the end of this year. EDIT-301 is made of patient-derived CD34+ haematopoietic stem and progenitor cells, which are edited using CRISPR at the gamma globin gene (HBG1 and HBG2) promoter sites using a proprietary engineered AsCas12a nuclease, per the company’s website. This increases the expression of fetal haemoglobin. Editas’ CRISPR therapies represent a different approach to the gene editing technology than the one used by CRISPR Therapeutics , which relies on the CRISPR/Cas9 platform . Earlier in the year, the company had announced a move towards developing treatments for hemoglobinopathies like sickle cell disease and beta thalassemia and a focus on in vivo discovery. In a January 9 press release, Editas stated it will be laying off roughly 20% of its workforce , alongside the discontinuation of its investments in its therapies for inherited retinal diseases. Specifically, this meant that the company stopped investments into EDIT-101 and its use in Leber Congenital Amaurosis and EDIT-103 for rhodopsin-associated autosomal retinitis pigmentosa. Editas also discontinued investments in its preclinical natural killer (NK) cell program, which included candidates like EDIT-202 for use in solid tumours. On January 19, Editas announced that it entered into a definitive agreement with Shoreline Biosciences for the licensing of its natural killer cell program. Shoreline acquired EDIT-202 as part of this agreement. Cell & Gene Therapy coverage on Pharmaceutical Technology is supported by Cytiva.
