1. what luxturna is and what it is used for

Luxturna is a gene therapy product that contains the active substance voretigene neparvovec.

Luxturna is used for the treatment of adults and children with vision loss due to inherited retinal dystrophy caused by mutations in the RPE65 gene. These mutations prevent the body from producing a protein needed for vision and so lead to loss of sight and eventual blindness.

The active substance in Luxturna, voretigene neparvovec, is a modified virus that contains a working copy of the RPE65 gene. After injection it delivers this gene into the cells of the retina, the layer at the back of the eye that detects light. This enables the retina to produce the proteins needed for vision. The virus used to deliver the gene does not cause disease in humans.

Luxturna will be given to you only if genetic testing shows that your vision loss is caused by mutations in the RPE65 gene.

2. what you need to know before you are given luxturna

You will not be given Luxturna

• – if you are allergic to voretigene neparvovec or any of the other ingredients of this medicine (listed in section 6)

• – if you have an eye infection

• – if you have eye inflammation

If any of the above applies to you, or if you are unsure of any of the above, please talk to your doctor before you receive Luxturna.

Warnings and precautions

Before receiving treatment with Luxturna:

• Tell your doctor if you have signs of an eye infection or eye inflammation, for example if you have eye redness, sensitivity to light, eye swelling or eye pain.
• Tell your doctor if you have an active infection of any sort. Your doctor may delay your treatment until your infection is gone because this medicine may make it more difficult for you to fight an infection. See also section 3.

After receiving Luxturna:

• Get immediate care from your doctor if your eye or eyes become red, painful, sensitive to light, you see flashes or floaters in your vision, or if you notice any worsening or blurred vision.
• You should avoid air travel or other travel to high elevations until advised by your doctor. During treatment with this medicine, the doctor inserts an air bubble in the eye, which is slowly absorbed by your body. Until the bubble is fully absorbed, air travel or other travel to high elevations may make the bubble expand and lead to eye damage, including vision loss. Please talk to your doctor before travelling.
• You should avoid swimming because of an increased risk of infection in the eye. Please talk to your doctor before going to swim after receiving treatment with Luxturna.
• You should avoid strenuous physical activity because of an increased risk of injury to the eye. Please talk to your doctor before beginning to engage in strenuous physical activity after receiving Luxturna.
• Some people develop cataracts. A cataract is clouding of the natural lens inside the eye that can make it harder to see clearly. The development or worsening of cataracts is a known complication of the eye surgery that will be required before you receive Luxturna. There is an additional risk of cataract if the lens inside the eye is damaged by the needle used to inject the medicine into the back of the eye.
• You may have temporary visual disturbances, such as light sensitivity, and blurred vision. Tell your doctor about any visual disturbances that you experience. Your doctor may be able to help reduce any discomfort caused by these temporary disturbances.
• Some medicine may be present in your tears. You and your caregiver should place any used dressings and waste material with tears and nasal secretions in sealed bags before disposing of them. You should follow these precautions for 14 days.
• You and your caregiver, especially if pregnant, breast-feeding or with a suppressed immune system, should wear gloves during dressing changes and when disposing of the dressings and other waste material. Follow these precautions for 14 days after the treatment.
• You will not be able to donate blood, organs, tissues and cells for transplantation after you have been treated with Luxturna.

Children and adolescents

Luxturna has not been studied in children under four years of age.

Other medicines and Luxturna

Tell your doctor if you are taking, have recently taken or might take any other medicines.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you might be pregnant, or are planning to have a baby, ask your doctor or nurse for advice before being treated with Luxturna.

The effects of this medicine on pregnancy and the unborn child are not known. As a precaution, you should not receive Luxturna while you are pregnant.

Luxturna has not been studied in breast-feeding women. It is not known whether it passes into breast milk. Ask your doctor whether you should stop breast-feeding after receiving Luxturna.

There is no information on the effect of Luxturna on male or female fertility.

Driving and using machines

You may have temporary visual disturbances after receiving Luxturna. Do not drive or use heavy machines until your vision has recovered. Talk to your doctor before resuming these activities.

Luxturna contains sodium

Luxturna contains less than 1 mmol sodium (23 mg) per dose, i.e. essentially ‘sodium-free’.

• 3. How Luxturna is given to you

Luxturna will be given to you in an operating room by surgeons experienced in performing eye surgery.

Luxturna is given under anaesthesia. Your doctor will talk to you about the anaesthesia and how it will be given to you.

Your doctor will carry out eye surgery to remove the clear gel inside the eye, and then inject Luxturna directly under your retina, the thin light-sensing layer at the back of that eye. This will be repeated on your other eye at least 6 days afterwards. You will need to stay for post-operative observation for a few hours after each procedure to monitor your recovery and watch for any side effects from the surgery or the anaesthesia.

Before Luxturna treatment is started, your doctor may prescribe a medicine that will suppress your immune system (the body’s natural defences) so that it will not try to fight the Luxturna when it is given. It is important that you take this medicine according to the instructions given. Do not stop taking the medicine without first talking to your doctor.

If you are given more Luxturna than you should be

As this medicine is given to you by a doctor, it is unlikely that you will be given too much. If it does occur, your doctor will treat the symptoms as necessary. Tell your doctor or nurse if you have any visual problems.

If you have any further questions on the use of this medicine, ask your doctor or nurse.

This medicine contains genetically modified organisms. Unused medicinal product must be disposed of in compliance with the local biosafety guidelines.

Preparation

Preparation of Luxturna should be performed, within 4 hours of beginning the administration procedure, in accordance with the following recommended procedures performed under aseptic conditions.

Thaw one single-dose vial of concentrate and two single-use vials of solvent at room temperature. Gently invert the thawed solvent vials five times to mix the contents.

Inspect for any visual particulates. Any anomalies or appearance of visual particulates should be reported to the Marketing Authorisation Holder and product should not be used.

Transfer 2.7 mL of the solvent taken from the two thawed vials and dispense into a sterile 10 mL glass vial using a 3 mL syringe.

For dilution, transfer 0.3 mL of thawed concentrate into a 1 mL syringe and add it to the 10 mL sterile vial containing the solvent. Gently invert the 10 mL glass vial at least five times for proper mixing. Label the 10 mL glass vial containing the diluted concentrate as follows: ‘Diluted Luxturna’.

Do not prepare syringes for injection if the vials show any damage or if any visual particulates are observed. Prepare the syringes for injection by drawing 0.8 mL of the diluted solution into each sterile 1 mL syringe. The product filled syringes should then be transferred in a designated transport container to the surgical suite.

Posology

Treatment should be initiated and administered by a retinal surgeon experienced in performing macular surgery.

Luxturna is a single-use vial for a single administration in one eye only. Each single dose of 1.5 × 1011 vg will be delivered into the subretinal space in a total volume of 0.3 mL per eye. The individual administration procedure to each eye should be performed on separate days within a close interval, but no fewer than 6 days apart.

immunomodulatory regimen

Prior to initiation of the immunomodulatory regimen and prior to administration of Luxturna, the patient must be checked for symptoms of active infectious disease of any nature, and in case of such infection the start of treatment must be postponed until after the patient has recovered.

Starting 3 days prior to the administration of Luxturna to the first eye, it is recommended that an immunomodulatory regimen is initiated following the schedule below (Table 1). Initiation of the immunomodulatory regimen for the second eye should follow the same schedule and supersede completion of the immunomodulatory regimen of the first eye.

Table 1 Pre- and post-operative immunomodulatory regimen for each eye

Pre-operative	3 days prior to Luxturna administration	Prednisone (or equivalent) 1 mg/kg/day (maximum of 40 mg/day)
Post-operative	4 days (including the day of administration)	Prednisone (or equivalent) 1 mg/kg/day (maximum of 40 mg/day)
	Followed by 5 days	Prednisone (or equivalent) 0.5 mg/kg/day (maximum of 20 mg/day)
	Followed by 5 days of one dose every other day	Prednisone (or equivalent) 0.5 mg/kg every other day (maximum of 20 mg/day)

Method of administration

Subretinal use.

Luxturna is a concentrate for solution for subretinal injection that requires thawing and dilution prior to administration.

This medicinal product must not be administered by intravitreal injection.

The product is administered as a subretinal injection after vitrectomy in each eye. It should not be administered in the immediate vicinity of the fovea to maintain foveal integrity.

The administration of voretigene neparvovec should be carried out in the surgical suite under controlled aseptic conditions. Adequate anaesthesia should be given prior to the procedure. The pupil of the eye to be injected must be dilated, and a broad-spectrum microbiocide should be topically administered prior to the surgery according to standard medical practice.

Precaution to be taken before manipulating or administering the product

Personal protective equipment (to include laboratory coat, safety glasses and gloves) should be worn while preparing or administering voretigene neparvovec.

Intraocular pressure should be monitored prior to and following administration of the product, and managed appropriately.

Following the administration, patients should be instructed to report any symptoms suggestive of retinal detachment or endophthalmitis without delay and should be managed appropriately.

Follow the steps below to administer Luxturna to patients:

• Diluted Luxturna should be inspected visually prior to administration. If particulates, cloudiness, or discoloration are visible, the product must not be used.
• Connect the syringe containing the diluted product to the extension tube and subretinal injection cannula. The product is slowly injected through the extension tube and subretinal injection cannula to eliminate any air bubbles.
• The volume of product available for injection is confirmed in the syringe, by aligning the plunger tip with the line that marks 0.3 mL.
• After vitrectomy is completed, Luxturna is administered by subretinal injection using a commercially available subretinal injection cannula introduced via pars plana.
• Under direct visualisation, the tip of the subretinal injection cannula is placed in contact with the retinal surface. The recommended site of injection is located along the superior vascular arcade, at least 2 mm distal to the centre of the fovea. A small amount of the product is slowly injected until an initial subretinal bleb is observed, and then, the remaining volume is slowly injected until the total 0.3 mL is delivered (Figure 1).

Figure 1 Tip of the subretinal injection cannula placed within recommended injection site (surgeon’s view)

• At the completion of the injection, the subretinal injection cannula is removed from the eye.
• Fluid-air exchange is performed, carefully avoiding fluid drainage near the retinotomy created for the subretinal injection.
• Supine head positioning is initiated immediately in the post-operative period and, upon discharge, patients should be advised to rest in a supine position as much as possible for 24 hours.
