Novartis enters into a licensing and supply agreement to develop, register and commercialize investigational gene therapy voretigene neparvovec outside the US; Spark Therapeutics retains US rights for LUXTURNA(TM) (voretigene neparvovec-rzyl)
Voretigene neparvovec is an investigational one-time gene therapy to restore functional vision for patients with biallelic mutations of the RPE65 gene
This investigational therapy provides patients with a working copy of the RPE65 gene to treat otherwise progressive vision loss that typically leads to blindness
Basel, January 24, 2018- Novartis today announced a licensing agreement with Spark Therapeutics covering development, registration and commercialization rights to voretigene neparvovec in markets outside the US. Voretigene neparvovec, known as LUXTURNA(TM) (voretigene neparvovec-rzyl) in the US, received FDA approval on December 19, 2017 as a one-time gene therapy to restore functional vision in children and adult patients with biallelic mutations of the RPE65 (retinal pigment epithelial 65 kDa protein) gene. The market authorization application (MAA) with the European Medicines Agency (EMA) was filed on July 31, 2017. Currently there is no existing therapy for this disease outside the US.
"No otherwise healthy child should have to go blind due to this devastating disease. Gene therapy is a promising new avenue to potentially address this unmet need," said Shreeram Aradhye, Global Head of Medical Affairs and Chief Medical Officer, Novartis Pharmaceuticals. "This collaboration builds on our commitment to ophthalmology. We look forward to leveraging our global presence to ensure that patients outside the US have access to this potentially life-changing treatment."
Novartis will make an upfront payment as well as pay milestones and royalties to Spark Therapeutics reflective of the late stage of the opportunity. Spark Therapeutics retains exclusive rights for LUXTURNA(TM) in the US and will retain responsibility for obtaining EMA approval. Commercialization rights will be transferred to Novartis upon successful completion of registration and issuance of market authorization. Novartis has exclusive rights to pursue development, registration and commercialization in all other countries outside the US. Spark Therapeutics will be responsible for the supply of voretigene neparvovec worldwide under a separate manufacturing and supply agreement with Novartis.
Mutations in the RPE65 gene lead to reduced or absent levels of RPE65 isomerohydrolase activity, blocking the visual cycle and resulting in progressive vision loss and ultimately, blindness. Only a few thousand people worldwide are affected by this ultra-orphan condition, . Pending approval, Novartis will work with physicians to establish new approaches to facilitating diagnosis and treatment at specialized treatment centers.
About Novartis in ophthalmology Novartis is a leading ophthalmology company, with therapies that treat both front and back of the eye disorders, including retina diseases, glaucoma, dry eye and other external eye diseases. In 2016, approximately 200 million patients worldwide were treated with Novartis ophthalmic products.
About LUXTURNA(TM) LUXTURNA(TM) is an adeno-associated virus (AAV) vector-based gene therapy indicated in the United States for the treatment of patients with confirmed biallelic RPE65 mutation-associated retinal dystrophy. Patients must have viable retinal cells as determined by the treating physician. Mutations in the RPE65 (retinal pigment epithelial 65 kDa protein) gene lead to reduced or absent levels of RPE65 isomerohydrolase activity, blocking the visual cycle and resulting in impairment of vision. Injection of LUXTURNA(TM) into the subretinal space results in transduction of some retinal pigment epithelial cells with a cDNA encoding normal human RPE65 protein, thus providing the potential to restore the visual cycle.
The safety data reflect exposure to LUXTURNA(TM) in two clinical trials consisting of 41 subjects (81 eyes) with confirmed biallelic RPE65 mutation-associated retinal dystrophy. 40 of the 41 subjects received sequential subretinal injections to each eye. The efficacy in pediatric and adult patients with biallelic RPE65 mutation-associated retinal dystrophy was evaluated in an open-label, two-center, randomized trial. The average age of the 31 randomized subjects was 15 years (range 4 to 44 years), including 64% pediatric subjects (n=20, age from 4 to 17 years) and 36% adults (n=11). The efficacy of LUXTURNA was established on the basis of multi-luminance mobility testing (MLMT) score change from Baseline to Year 1.
Indication and Important Safety Information LUXTURNA (voretigene neparvovec-rzyl) is an adeno-associated virus vector-based gene therapy indicated for the treatment of patients with confirmed biallelic RPE65 mutation-associated retinal dystrophy.
Patients must have viable retinal cells as determined by the treating physicians.
Warnings and Precautions
Endophthalmitis may occur following any intraocular surgical procedure or injection. Use proper aseptic injection technique when administering LUXTURNA, and monitor for and advise patients to report any signs or symptoms of infection or inflammation to permit early treatment of any infection.
Permanent decline in visual acuity may occur following subretinal injection of LUXTURNA. Monitor patients for visual disturbances.
Retinal abnormalities may occur during or following the subretinal injection of LUXTURNA, including macular holes, foveal thinning, loss of foveal function, foveal dehiscence, and retinal hemorrhage. Monitor and manage these retinal abnormalities appropriately. Do not administer LUXTURNA in the immediate vicinity of the fovea. Retinal abnormalities may occur during or following vitrectomy, including retinal tears, epiretinal membrane, or retinal detachment. Monitor patients during and following the injection to permit early treatment of these retinal abnormalities. Advise patients to report any signs or symptoms of retinal tears and/or detachment without delay.
Increased intraocular pressure may occur after subretinal injection of LUXTURNA. Monitor and manage intraocular pressure appropriately.
Expansion of intraocular air bubbles Instruct patients to avoid air travel, travel to high elevations or scuba diving until the air bubble formed following administration of LUXTURNA has completely dissipated from the eye. It may take one week or more following injection for the air bubble to dissipate. A change in altitude while the air bubble is still present can result in irreversible vision loss. Verify the dissipation of the air bubble through ophthalmic examination.
Cataract Subretinal injection of LUXTURNA, especially vitrectomy surgery, is associated with an increased incidence of cataract development and/or progression.
In clinical studies, ocular adverse reactions occurred in 66% of study participants (57% of injected eyes), and may have been related to LUXTURNA, the subretinal injection procedure, the concomitant use of corticosteroids, or a combination of these procedures and products.
The most common adverse reactions (incidence >= 5% of study participants) were conjunctival hyperemia (22%), cataract (20%), increased intraocular pressure (15%), retinal tear (10%), dellen (thinning of the corneal stroma) (7%), macular hole (7%), subretinal deposits (7%), eye inflammation (5%), eye irritation (5%), eye pain (5%), and maculopathy (wrinkling on the surface of the macula) (5%).
Immunogenicity Immune reactions and extra-ocular exposure to LUXTURNA in clinical studies were mild. No clinically significant cytotoxic T-cell response to either AAV2 or RPE65 has been observed. Study participants received systemic corticosteroids before and after subretinal injection of LUXTURNA to each eye, which may have decreased the potential immune reaction to either AAV2 or RPE65.
Pediatric Use Treatment with LUXTURNA is not recommended for patients younger than 12 months of age, because the retinal cells are still undergoing cell proliferation, and LUXTURNA would potentially be diluted or lost during the cell proliferation. The safety and efficacy of LUXTURNA have been established in pediatric patients. There were no significant differences in safety between the different age subgroups.
