Luxturna (Voretigene Neparvovec-Rzyl)

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

    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.

    Routes of administration

    Subretinal injection (surgical procedure)

    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 chloride
    • Sodium phosphate (monobasic and dibasic)
    • Magnesium chloride
    • Potassium chloride
    • Calcium chloride
    • Glucose
    • Poloxamer 188
    • Water for injection

    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
    • Cataract
    • Conjunctival hyperemia
    • Eye pain
    • Macular hole or thinning
    • Retinal hemorrhage
    • Subretinal deposits

    Serious adverse effects may include:

    • Endophthalmitis
    • Retinal detachment or tear
    • Macular atrophy
    • Loss of visual acuity

    Patients should be monitored postoperatively for ocular complications and managed accordingly.
