Description
Luxturna (voretigene neparvovec-rzyl) is a gene therapy indicated for the treatment of patients with confirmed biallelic RPE65 mutation-associated retinal dystrophy, a rare inherited condition that leads to progressive vision loss and eventual blindness. It is the first FDA-approved gene therapy for an inherited retinal disease. Luxturna delivers a functional copy of the RPE65 gene directly to retinal cells through a subretinal injection, enabling production of the RPE65 protein, which is essential for the visual cycle and photoreceptor function.

Directions
Luxturna is administered as a one-time subretinal injection in each eye, with the second eye treated no sooner than 6 days after the first. Each eye receives 1.5 × 10¹¹ vector genomes (vg) in a total volume of 0.3 mL.
- Patients must receive systemic corticosteroids (e.g., prednisone 1 mg/kg/day) starting 3 days before the first injection, continuing for a total of 7 days, and then tapered over the next 10 days.
- Administration must be performed by a retinal surgeon experienced in subretinal injections under controlled surgical conditions.
Ingredients
Each vial of Luxturna contains:
- Voretigene neparvovec-rzyl 5 × 10¹² vector genomes/mL (in 0.5 mL)
- Sodium phosphate (monobasic and dibasic)
The product is preservative-free and supplied as a frozen suspension requiring thawing and dilution prior to administration.
Contraindications
Luxturna is contraindicated in patients with:
- Active ocular or periocular infection
- Active intraocular inflammation
Cautions
- Endophthalmitis, retinal tears, increased intraocular pressure, and macular abnormalities may occur after injection.
- Use caution in patients with pre-existing retinal thinning or degeneration.
- Immune responses to the AAV vector or transgene may occur; immunosuppressive therapy is required.
- Bilateral simultaneous administration is not recommended due to potential complications.
- Avoid air travel or high-altitude environments until intraocular gas used during surgery is fully absorbed to prevent increased intraocular pressure.
Side Effects
Common side effects of Luxturna include:
- Ocular inflammation (e.g., anterior chamber or vitreous cells)
- Increased intraocular pressure
Serious adverse effects may include:
- Retinal detachment or tear
Patients should be monitored postoperatively for ocular complications and managed accordingly.
