MeiraGTx paid $25 million to buy back a gene therapy that J&J acquired for up to $415 million, after the program's Phase 3 trial missed its primary endpoint. Now the company is racing to file for approval anyway, betting that J&J walked away too soon.
Imagine selling your car for $130,000, watching the new owner crash it, then buying it back for $25,000. That's roughly what just happened in the gene therapy world.
MeiraGTx, a clinical-stage biotech focused on genetic medicines for the eye, announced on April 16 that it reacquired full global rights to botaretigene sparoparvovec (mercifully nicknamed "bota-vec") from Johnson & Johnson. The price tag: $25 million upfront, plus a future milestone payment tied to approval and royalties on sales. J&J originally paid up to $415 million for the program, including $130 million upfront, back in 2023.
That's a 94% discount. Black Friday has nothing on a failed Phase 3 trial.
Bota-vec is a gene therapy designed to treat X-linked retinitis pigmentosa (XLRP), a rare inherited condition where patients gradually lose their vision due to mutations in the RPGR gene. Think of it like a software bug in the cells that detect light: bota-vec delivers a working copy of the code using an engineered virus (called an AAV vector) injected beneath the retina.
J&J ran a Phase 3 trial called LUMEOS for bota-vec. In May 2025, the results came in, and they weren't what anyone hoped for. The trial missed its primary endpoint, which measured whether patients could navigate better in low-light conditions (a standardized test called vision-guided mobility). In plain English: the main thing the trial was supposed to prove didn't pan out.
For J&J, that was enough to walk away. Big pharma companies manage sprawling portfolios; a gene therapy that stumbles in Phase 3 for a rare eye disease doesn't always survive the next budget meeting. But for MeiraGTx, which originally developed bota-vec and has been living and breathing ocular gene therapy for years, the story looked different.
MeiraGTx isn't ignoring the Phase 3 miss. They're arguing the trial told a more nuanced story than the headline suggests.
While bota-vec didn't hit the primary endpoint, the company says it showed . Doctors at the trial sites apparently agreed; MeiraGTx has emphasized strong investigator feedback and deep relationships with key opinion leaders who treated patients in the study.

For decades, patients with a rare kidney disease called FSGS had zero approved treatments. Travere Therapeutics just changed that with the first-ever FDA-approved therapy, and Wall Street thinks it could be worth $2 billion.

This is a bit like a movie that bombs at the box office but gets rave reviews from critics. The commercial scorecard said one thing, but the people closest to the data saw something else. Whether regulators agree is the billion-dollar question.
MeiraGTx plans to file for approval in both the U.S. and EU immediately, targeting a potential launch in 2027 if everything goes smoothly. That's an aggressive timeline for a program whose pivotal trial technically failed, but the company clearly believes the secondary data package is strong enough to make the case.
Reacquiring bota-vec wasn't the only thing MeiraGTx announced that day. The company also priced a $100 million public stock offering at $9 per share, giving it the cash to fund the regulatory push and a potential commercial launch.
The stock has had a wild ride. Shares traded between $4.55 and $9.88 over the past year, and the offering was priced near the top of that range. Wall Street analysts seem cautiously optimistic: the consensus rating sits at Moderate Buy, with average price targets between $23 and $26. That implies analysts see the stock roughly tripling from current levels. Of course, analyst targets and reality don't always travel in the same zip code.
MeiraGTx also brings a major structural advantage to the table. The company completed process performance qualification (PPQ) for manufacturing bota-vec, meaning it can produce the therapy in-house. In gene therapy, where manufacturing is often the hardest and most expensive bottleneck, owning your own production is like a restaurant growing its own ingredients. It keeps costs down and timelines under control.
Bota-vec isn't MeiraGTx's only iron in the fire. The company has been assembling a broader ophthalmology platform that includes multiple late-stage programs.
In November 2025, Eli Lilly signed a deal worth $75 million upfront (with milestones exceeding $400 million) for rights to AAV-AIPL1, another MeiraGTx gene therapy targeting Leber congenital amaurosis type 4, a devastating form of childhood blindness. That deal also gave Lilly access to MeiraGTx's technology toolkit: intravitreal capsids (virus shells designed for injection into the eye's interior), AI-generated promoters (genetic switches that control where and when a gene turns on), and a riboswitch platform that lets doctors dial gene expression up or down with an oral pill.
In February 2026, MeiraGTx added another piece by licensing geographic atrophy therapies from ZipBio. The company is clearly building something bigger than any single product.
The ocular gene therapy space is surprisingly sparse at the commercial stage. Luxturna, made by Spark Therapeutics (now owned by Roche), remains the only approved gene therapy for an inherited retinal disease. It treats a different condition, RPE65-mediated Leber congenital amaurosis, and has been on the market since 2017.
Behind Luxturna, the pipeline is crowded but early. More than 75 companies are developing over 80 AAV-based gene therapy candidates targeting inherited retinal diseases, with AAV-based approaches dominating about 90% of the pipeline. Competitors include REGENXBIO (partnered with AbbVie), Adverum Biotechnologies, 4D Molecular Therapeutics, and Beacon Therapeutics. But most of these programs are in Phase 2 or earlier.
If MeiraGTx can convince regulators that bota-vec's secondary data justifies approval, it could become only the second ocular gene therapy to reach patients. That's a powerful position in a market with massive unmet need.
This deal is a fascinating bet. MeiraGTx is wagering $25 million (plus $100 million in fresh capital) that J&J was wrong to give up on bota-vec. The Phase 3 miss is a real obstacle, and there's no guarantee the FDA or EMA will be persuaded by secondary endpoints when the primary one fell short.
But there's a reason the company jumped at this. They know the data better than anyone, they own the manufacturing, and they have the clinical relationships to make a regulatory case. At $25 million for a program that was valued at $415 million just three years ago, the risk-reward math is hard to argue with.
Sometimes the best deals in biotech aren't the ones that make headlines at signing. They're the ones that get quietly returned to sender.
Storm Therapeutics just raised $56 million and dosed the first patient in a Phase 2 sarcoma trial, all for a drug targeting an enzyme most people have never heard of. It's the biggest clinical milestone yet for epitranscriptomics, a therapeutic field that literally didn't exist a decade ago.
