Optogenetic Therapy for Restoring Visual Function — NEJM Clinical Trial Report

Study overview and publication details

The PubMed record describes a clinical-trial report titled Optogenetic Therapy for Restoring Aspects of Visual Function published in the New England Journal of Medicine (N Engl J Med) on 2026 Oct 8 (395:1399–1408). The entry is indexed with PMID 42842903 and DOI 10.1056/NEJMoa2602215. The PubMed page for this article identifies the work as a Clinical Trial but the supplied excerpt does not include the article abstract or the body text.

Authors and institutional affiliations

The PubMed entry lists José-Alain Sahel as the lead author and a large multidisciplinary team of coauthors. Reported institutional affiliations in the record include:

• Department of Ophthalmology, University of Pittsburgh School of Medicine, Pittsburgh.
• Sorbonne Université; Institut National de la Santé et de la Recherche Médicale (Inserm); Centre National de la Recherche Scientifique (CNRS); Institut de la Vision, Paris.

The PubMed listing includes many named coauthors across these centers; the excerpt reproduced their names and corresponding affiliations but did not present additional biographical or contributorship detail beyond institutional listings.

Clinical-trial designation and identifiers

The PubMed record explicitly classifies the publication as a Clinical Trial. Identifiers available in the excerpt are:

• PubMed Identifier (PMID): 42842903
• Digital Object Identifier (DOI): 10.1056/NEJMoa2602215

These identifiers can be used to locate the full text through journal access, DOI resolution, or institutional/ library resources.

Available information from the PubMed entry

From the supplied PubMed excerpt, the following are available and verifiable:

• Article title and publication citation (journal, date, volume, issue, pages).
• Full list of authors as shown on the PubMed page.
• Institutional affiliations linked to authors.
• Classification as a Clinical Trial.
• PMID and DOI.

The PubMed record also includes standard site navigation elements and administrative metadata typical of NCBI PubMed pages, but the excerpt does not provide the article abstract, figures, tables, methods, or results.

Key trial details not reported in the provided source

The excerpted PubMed content did not include core study information needed for clinical interpretation. Specifically, the following details were not reported in the provided source text and therefore cannot be summarized or paraphrased here:

• Trial objectives, hypotheses, or primary and secondary endpoints.
• Study design details (randomization, masking/blinding, control group, comparator, dosing strategy, device or vector specifics).
• Eligibility criteria and participant baseline characteristics, including sample size and demographic breakdown.
• Description of the optogenetic intervention (therapeutic construct, delivery method, device specifications, light parameters) and any adjunctive therapies.
• Safety and adverse-event data.
• Efficacy outcomes, statistical analyses, effect sizes, and p values.
• Duration of follow-up and longitudinal outcome data.
• Authors' conclusions, clinical recommendations, or regulatory status implications.

Because these elements were not present in the supplied PubMed excerpt, any interpretation about efficacy, safety, or clinical utility would require consulting the full article.

Summary

The provided PubMed excerpt documents a NEJM clinical-trial publication titled Optogenetic Therapy for Restoring Aspects of Visual Function with full authorship and institutional affiliations and includes PMID and DOI identifiers. The excerpt does not include the abstract or study data; therefore, no trial outcomes, safety results, or methodological specifics can be reported from this source alone. For comprehensive evaluation, retrieve and review the full article via the DOI, PubMed record, or journal access.
