Novartis announced today that the Japanese Ministry of Health, Labour and Welfare (MHLW) approved Cosentyx(TM) (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.
