Novartis announced the US Food and Drug Administration (FDA) has approved Cosentyx® (secukinumab) for the treatment of active enthesitis-related arthritis (ERA) in four years and older, and active juvenile psoriatic arthritis (JPsA) in patients two years and older. Cosentyx is now the first biologic indicated for ERA, and the only biologic treatment approved for both ERA and PsA in pediatric patients in the US. These are the second and third approvals for Cosentyx in a pediatric population in the US, and Cosentyx now has a total of five indications across rheumatology and dermatology. ERA and JPsA, subtypes of juvenile idiopathic arthritis (JIA), are autoimmune diseases. ERA is characterized by joint swelling and pain where tendons and ligaments attach to bone and may present with low back pain or tenderness at the palpation of the hips. JPsA is characterized by joint swelling and skin psoriasis and may present with nail changes, inflammation of fingers and/or toes or psoriatic skin changes in a first-degree relative. If left untreated, they can lead to high levels of pain and disability. The approved pediatric dosing for Cosentyx in children and adolescents is 75 mg (15 kg or more to less than 50 kg) or 150 mg (50 kg or more). It is administered as a subcutaneous injection by a pre-filled syringe or Sensoready® pen every 4 weeks after initial loading doses. With appropriate guidance/instruction from a healthcare professional, Cosentyx can be administered by an adult caregiver outside of a healthcare provider’s office via a single-dose prefilled syringe or Sensoready® pen. The approval is based on data from the Phase III JUNIPERA study, a two-year, three-part, double-blind, placebo-controlled, randomized-withdrawal trial that enrolled 86 children and adolescents aged 2 to 18 years old with a confirmed diagnosis of ERA or JPsA according to a modified International League of Associations for Rheumatology classification criteria. The primary endpoint of the study was time to flare in the treatment period 2 (Week 12 to Week 104)7. In children and adolescents aged 2 to 18 years old, the study demonstrated that patients with active JPsA (n = 34; mean age: 12.2) treated with Cosentyx had a longer time to flare, showing an 85% reduction in the risk of flare (P Cosentyx is the first and only fully human biologic that directly inhibits interleukin-17A (IL-17A), an important cytokine involved in the inflammation of psoriatic arthritis (PsA), moderate to severe plaque psoriasis, ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA)12,13. Cosentyx is a proven medicine and has been studied clinically for more than 14 years. The medicine is backed by robust evidence, including 5 years of clinical data in adults supporting long-term safety and efficacy across moderate to severe plaque psoriasis, PsA and AS14-20. These data strengthen the position of Cosentyx as a treatment across AS, nr-axSpA, PsA and moderate to severe plaque psoriasis, supported by more than 500,000 patients treated worldwide since launch in 2015.
