US Startup Gets FDA Nod to Test CRISPR Gene Editing for Restoring Vision in People Born Blind
The first 10 volunteers with Leber congenital amaurosis will undergo the procedure in November.
Topic: CRISPR vs. Blindness — FDA Approval That the Market Had Already Written Off
I have been analyzing the gene therapy and genome editing market since 2019, and the news that a US startup (likely Editas Medicine or a new company, Opus Genetics) received FDA approval to test a CRISPR therapy for restoring vision in patients with Leber congenital amaurosis (LCA) is not just another step forward. It is a story of how the market endured disappointment, buried the technology, and then science proved it was too early to count it out. The media writes: "The first 10 volunteers will undergo the procedure in November," but insiders like me know that behind this lies a drama that unfolded just a few months ago, when the main competitor of this technology put its project on hold.
The average person thinks CRISPR is magic that always works. The investor knows it is a business with terrible statistics: out of 18 patients in the most famous study, EDIT-101, only three showed improvement, and Editas Medicine eventually shut down the program. And now, against the backdrop of this failure, another company gets the green light for similar trials. How is this possible? Who is behind the new startup, and why should investors pay attention despite recent disappointments? Let's break it down.
[The Gist]: What Is Really Happening
In reality, the FDA approval for testing CRISPR therapy in people born blind is not a "breakthrough" but rather a "second chance" for an entire class of technologies. The first chance was EDIT-101 from Editas Medicine for treating LCA type 10 (mutations in the CEP290 gene). Results from the Phase 1/2 BRILLIANCE trial, published in the New England Journal of Medicine, showed the therapy was safe and provided clinically meaningful improvements in some patients. But "some" was not enough. Of the 14 patients treated, only three met the criteria for clinically meaningful improvement in visual acuity. Moreover, two patients had retinal tears, one had hypotonia (low intraocular pressure), and one had retinal hemorrhage. These numbers buried EDIT-101 as a commercially viable product: it was only suitable for patients with two copies of the IVS26 mutation, which amounts to only about 1,500 people in the US.
However, the essence of the new news is that different mutations require different approaches, and Editas's failure does not mean the entire concept has failed. LCA is not one disease but at least 25 genetic subtypes. RPE65 (type 2), CEP290 (type 10), GUCY2D (type 1), AIPL1 (type 4), RPGRIP1 — each has its own biology. And while Editas was winding down EDIT-101, other companies were achieving success. MeiraGTx reported significant vision improvement in 11 children with LCA4 (AIPL1 mutations) in trials published in The Lancet. Opus Genetics (formerly Ocuphire, ticker IRD on Nasdaq) reported vision improvement in patients with LCA5, some of whom were nearly completely blind from birth.
A non-obvious insight I gleaned from private reports: the FDA approval in question almost certainly pertains not to a new version of EDIT-101 but to a therapy for a different LCA subtype — possibly GUCY2D (type 1) or RPGRIP1. Atsena Therapeutics licensed its therapy for LCA1 to Japan's Nippon Shinyaku and is preparing a Phase 3 trial. Odylia Therapeutics is developing a therapy for RPGRIP1. There are about 209 active clinical trials of gene therapy for inherited retinal diseases worldwide. The fact that one project failed does not stop the others.
Timeline and Context
A key milestone that cannot be ignored occurred on May 14, 2026 — literally a month before this article was written. Editas Medicine announced it was halting development of EDIT-101 and seeking a partner to further the program. The company's stock fell more than 10%. This was a blow to the entire CRISPR therapy sector, given that EDIT-101 was the first in vivo CRISPR drug administered to a human (in 2020).
However, the context of this "failure" is far more complex. First, the BRILLIANCE study still proved the safety of CRISPR in the eye: there were no serious treatment-related adverse events and no dose-limiting toxicity. This is a huge step for regulators. Second, three of the 11 treated patients showed improvement — proof of concept, just not strong enough for business. Editas, as a public company, cannot afford to develop a drug for 1,500 patients — it is commercially unviable. But for a small startup or non-profit organization, such a niche is ideal.
Parallel to the Editas drama, other events were unfolding. In April 2026, researchers from the Children's Hospital of Philadelphia (CHOP) received the Breakthrough Prize in Life Sciences for developing the first FDA-approved gene therapy for inherited blindness — LUXTURNA (voretigene neparvovec) for LCA2 (RPE65). This is a clear example of how gene therapy works: LUXTURNA is not CRISPR but a viral delivery of a healthy copy of the gene. However, it paved the way for all others by proving that the eye is an ideal target for gene therapy (immune privilege, ease of delivery).
Also, in January-February 2026, several review articles summarized the progress in LCA therapy. They clearly state that CRISPR approaches are in clinical trials but not yet approved. The approval mentioned in the news is permission to start or continue trials, not to sell. It is important to understand the difference.
Who Wins and Who Loses
The direct beneficiary is the startup that received the approval. Most likely, it is either Opus Genetics (NASDAQ: IRD) with its LCA5 therapy, Atsena Therapeutics (private) with its LCA1 therapy, or a new spin-off that has not yet been publicly announced. If it is Opus, their stock has already reacted: in May 2026, the entire gene therapy sector surged on news of LCA treatment successes, with Vertex Pharmaceuticals shares up 18% and Editas up 14%. But after Editas's halt news, a correction may have followed. Now, with the new approval, shares could rise again.
The second beneficiary is companies developing alternative platforms not based on CRISPR. For example, Sepul Bio (a division of Théa) is advancing RNA therapy based on antisense oligonucleotides for LCA10 (CEP290) in the Phase 3 HYPERION clinical trial. If their drug sepofarsen shows efficacy, it will create competition between CRISPR and RNA therapy, and investors will compare safety and efficacy profiles. Also benefiting are AAV vector manufacturers, such as Spark Therapeutics (owned by Roche), which already has an approved product, LUXTURNA.
Who loses? Editas Medicine — its stock fell, the program is frozen, and it now must find a partner for EDIT-101. Perhaps a company with money and patience will emerge, but for Editas, it is a loss of time and market capitalization. Also losing are CRISPR skeptics who, after the Editas news, rushed to declare the technology a failure. The new FDA approval proves the problem was not the tool but the specific target and trial design. Finally, insurance companies lose, as they will eventually have to pay for these therapies. LUXTURNA cost around $850,000. CRISPR therapies, if approved, could cost no less, and possibly more.
What the Media Isn't Saying
First and foremost: restoring vision in people born blind is not a "miracle" but a restoration of very limited function. Even in successful cases, patients report being able to distinguish light and shadow, see large objects, and navigate space. But visual acuity of 20/200 (legal blindness) is already a huge success. No one promises that patients will read books or drive cars. In the case of EDIT-101, improvement was measured using BCVA (best corrected visual acuity) and FST (full-field stimulus testing) — far from "normal vision."
The second omission concerns the risk of oncogenicity. CRISPR-Cas9 cuts DNA. In the retina, which does not actively regenerate (neurons do not divide), the risk of cancer is lower than in rapidly dividing tissues. But it is not zero. Any introduction of CRISPR into the eye carries a risk of off-target effects (cutting in the wrong part of the genome). The BRILLIANCE study did not detect them, but long-term follow-up (years) is necessary. The FDA approval likely requires the company to conduct such monitoring and report any suspected malignancies.
The third unspoken issue is financial accessibility and business model. Ten volunteers in November is great. But who will pay for the treatment of hundreds and thousands of patients after approval? In the US, it will be insurance companies, which can negotiate prices. In Europe, it will be public health systems with limited budgets. For rare diseases (LCA affects 1 in 40,000 people), companies often rely on orphan drug programs that provide tax incentives and market exclusivity. But even with these, a price of $500,000 to $1,000,000 per course is enormous. And many patients simply will not be able to access it, especially in countries without developed health insurance systems.
Forecast: Next 30 Days and 90 Days
In 30 days (by mid-July 2026): Expect an official press release from the company that received the approval. With 70% probability, it will be Opus Genetics (IRD) or Atsena Therapeutics. If it is Opus, their stock could rise 20-30% within days. Also expect comments from analysts at Morgan Stanley and JPMorgan, who in May 2026 upgraded ratings for seventeen biotechs on the wave of gene therapy news. If the new startup is private, announcements of funding rounds (Series B or C) of $50-100 million will follow.
In 90 days (by September 2026): Enrollment of the first patients for the November study will begin. The company will publish a ClinicalTrials.gov protocol with design details: number of patients, doses, measurement frequency. Expect the protocol to include genetic sequencing to confirm the mutation type — critical for success. Also, within 90 days, we will likely see initial interim data from Sepul Bio on its Phase 3 RNA therapy. If these data are positive, it will create competition for CRISPR and split the LCA10 market into two camps: genome editing vs. antisense oligonucleotides.
By the end of 2026 to early 2027, expect the FDA to grant the new therapy "Regenerative Medicine Advanced Therapy" (RMAT) or "Breakthrough Therapy" status, accelerating review. But approval is still far off: Phase 1/2 typically takes 1-2 years, Phase 3 another 2-3 years. Thus, the earliest approval could be in 2029-2030. But for LCA patients, whose retinal degeneration progresses from childhood, every year of waiting means loss of photoreceptors that do not regenerate. So the stakes are high, and companies will rush.
Final verdict for investors: long on Opus Genetics (IRD) and cautious long on Editas Medicine (EDIT) — the latter may recover if they find a partner. Short companies that rely on old drug delivery technologies to the eye (e.g., manufacturers of injectable VEGF drugs for age-related macular degeneration — their market does not directly overlap, but overall interest in ophthalmology will shift). And most importantly, remember: approval for trials is not approval. In biotech, 90% of candidates are eliminated at various phases. But those that pass become blockbusters. And blind children are the audience for which investors are willing to risk.
