- Luxturna* (voretigene neparvovec) is the first gene therapy to treat an inherited retinal disease, indicated for children and adults with vision loss caused by mutations in both copies of the RPE65 gene and sufficient viable retinal cells
- Nearly 60% of patients have severe forms of the disease, with severe visual impairment occurring shortly after birth
- As a one-time treatment, Luxturna restores vision and improves sight in children and adults with a sustained effect and favorable safety profile ,
People born with mutations in both copies of the RPE65 gene can experience profound sight loss from an early age, with the majority of patients progressing to total blindness. Research shows that vision impairment and blindness in children frequently cause social isolation, emotional distress, loss of independence, or hazards such as falls and injuries. The working copy of the RPE65 gene provided by Luxturna can restore vision and improve sight in children and adults with sufficient viable retinal cells.
"Today’s approval is momentous for patients given that there have been no pharmacological treatment options to date to treat this form of LCA," said Christina Fasser, president of Retina International, an umbrella organization of more than 43 patient organizations worldwide promoting research to find treatments for inherited retinal degenerative diseases. "Access to this treatment has the potential to reduce the substantial physical, emotional and financial burden this disease has on patients and their families."
"As a clinician who has worked for over 20 years with patients with inherited retinal disease and their families, I’ve seen firsthand the profound impact blindness can have on quality of life. It’s exciting to practice medicine at a time when we can offer options to children and adults facing blindness," said Dr Bart Leroy, ophthalmologist and clinical geneticist, Professor and Head, Department of Ophthalmology at Ghent University Hospital, Ghent, Belgium and Director of Retinal Degenerations Clinic at Children’s Hospital of Philadelphia, Philadelphia, PA. "After more than 20 years of gene therapy research, there is finally a promising future ahead for the treatment of rare genetic eye disorders."
"EU approval of the one-time gene therapy Luxturna marks a milestone in reimagining medicine and can bring real value to patients, their families and society as a whole," said Paul Hudson, CEO, Novartis Pharmaceuticals. "Novartis is committed to working with patients, caregivers, health systems and physicians to establish access to this gene therapy for RPE65 patients, as we believe it can help restore sight and improve vision in children and adults who currently have no treatment options."
The EC decision is based on a positive CHMP opinion that looked at data from a Phase 1 clinical trial, its follow-up trial, and the first randomized, controlled Phase 3 gene therapy trial for an inherited disease. In the Phase 3 clinical trial vision improvement was recorded as early as 30 days following treatment. At 1 year, compared to the control group, patients treated with voretigene neparvovec improved by 1.6 light levels on the binocular multi-luminance mobility test (MLMT), the trial’s novel, patient-centric, primary endpoint. Vision improved by one or more light levels for 90% of patients treated with voretigene neparvovec, and 65% were able to successfully navigate the MLMT at the lowest light level of 1 lux at 1 year.
Decisions from national reimbursement bodies on Luxturna for patients with vision loss due to a genetic mutation in both copies of the RPE65 gene are expected in 2019 and 2020. Novartis is working closely with all stakeholders to help ensure that eligible patients can start benefitting from this treatment as quickly as possible once reimbursement decisions are available in 2019 and 2020. A range of resources and innovative reimbursement and access approaches are also being explored in order to provide as much support as possible to both patients and healthcare professionals.
About RPE65 mutation-associated inherited retinal disease Inherited retinal diseases are a group of rare blinding conditions caused by more than 250 different genes , often disproportionally affecting children and young adults. Mutations in both copies of the RPE65 gene affect approximately 1 in 200,000 people.
Mutations in both copies of the RPE65 gene can lead to blindness. Early in the disease patients can suffer from night blindness (nyctalopia), loss of light sensitivity, loss of peripheral vision, loss of sharpness or clarity of vision, impaired dark adaptation and repetitive uncontrolled movements of the eye (nystagmus) . Patients with mutations in both copies of the RPE65 gene may be diagnosed, for instance, with subtypes of either Leber congenital amaurosis or retinitis pigmentosa. A genetic test is needed to confirm that vision loss is caused by mutations in the RPE65 gene.
About the multi-luminance mobility test (MLMT) The MLMT measures changes in patient relevant functional vision by asking patients to navigate a course accurately and at a reasonable pace at seven different levels of illumination, ranging from 400 lux (corresponding to a brightly lit office) to one lux (corresponding to a moonless summer night) .
About Luxturna’s mechanism of action Luxturna is the first EU-approved treatment for this disease and is designed to provide a working copy of the RPE65 gene to act in place of the mutated RPE65 gene.
About the Novartis and Spark Therapeutics licensing and supply agreement In January 2018, Spark Therapeutics entered into a licensing and supply agreement with Novartis covering development, registration and commercialization rights to Luxturna in markets outside the US. Upon the transfer of the marketing authorization from Spark Therapeutics to Novartis, Novartis can commercialize Luxturna in the EU/EEA. Novartis already has exclusive rights to pursue development, registration and commercialization in all other countries outside the US, and Spark Therapeutics will supply the gene therapy to Novartis.
