Novartis’ Cosentyx gets approval in Japan

Cosentyx approval is based on phase III programme demonstrating high, sustained efficacy in the skin clearance of moderate-to-severe plaque psoriasis

20150215ep15Japanese Ministry of Health, Labour and Welfare (MHLW) has approved Novartis’ Cosentyx (secukinumab, formerly known as AIN457), for the treatment of both psoriasis vulgaris and psoriatic arthritis (PsA) in adults who are not adequately responding to systemic therapies (except for biologics). This approval marks the first country approval for Cosentyx in the world and makes it the first interleukin-17A (IL-17A) inhibitor to receive regulatory approval in either of these indications in Japan.

Cosentyx works by inhibiting the action of IL-17A, a protein that is found in high concentrations in skin affected by psoriasis and central to the development of inflammatory diseases, including psoriasis and PsA[14-19]. As approximately 30 per cent of psoriasis patients are also affected by PsA globally[12], this approval means that these patients in Japan now have a new treatment option that effectively treats both diseases.

In psoriasis clinical trials, 70 per cent of patients achieved clear or almost clear skin within the first 16 weeks of treatment with Cosentyx 300 mg (p<0.0001), which was maintained in the majority of patients up to Week 52 (with continued treatment)[1]. In the PsA trials, Cosentyx demonstrated significant and sustained efficacy versus placebo in improving signs and symptoms of PsA, as measured by a 20 per cent reduction in the American College of Rheumatology response criteria (ACR 20), which is a standard criteria to assess the effectiveness of arthritis treatments. Between 50- 54 per cent of Cosentyx patients achieved at least ACR 20 in two pivotal studies, FUTURE 1 (150 mg; p<0.0001) and FUTURE 2 (150 and 300 mg; p<0.0001)[4],[5].

Psoriasis is a chronic immune-mediated disease characterised by thick and extensive skin lesions, called plaques, known to cause itching, scaling and pain; it is associated with significant impairment of physical and psychological quality of life[6],[20],[21]. Closely linked with psoriasis, PsA causes joint pain and stiffness, skin and nail psoriasis, swollen toes and fingers, persistent painful tendonitis and irreversible joint damage[13]. Up to 40 per cent of people can suffer from joint destruction and permanent physical deformity[22].

This approval was based on the safety and efficacy results from more than 10 phase II and phase III studies which included nearly 4,000 patients with moderate-to-severe plaque psoriasis[1-3],[13] and supported by two pivotal phase III studies, FUTURE 1 and FUTURE 2, involving more than 1,000 patients with PsA[4],[5]. In all studies, Cosentyx demonstrated a favourable safety profile, with similar incidence and severity of adverse events (AEs) between Cosentyx treatment arms (300 mg and 150 mg)[1-5],[23].

US Food and Drug Administration (FDA) approval in the same indication is anticipated in early 2015 following the unanimous recommendation of approval in October 2014 from the Dermatologic and Ophthalmic Drugs Advisory Committee (DODAC) to the US FDA.
