EMEA Recommends Marketing Authorisation of Ipsen's Adenuric(R) (Febuxostat) for the Treatment of Chronic Hyperuricaemia in Gout

Regulatory News: Ipsen (Paris:IPN) announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMEA) provided a positive opinion for Adenuric® (febuxostat) 80 mg and 120 mg tablets for the treatment of chronic hyperuricaemia in gout and recommended it for marketing authorisation. The CHMP recommendation will now be forwarded to the European Commission for final marketing approval, which typically occurs within 60 to 90 days. Following marketing approval, Adenuric® will become, since 1964, the first significant treatment alternative for chronic hyperuricaemia available to gout patients. Adenuric® is to be indicated for the treatment of chronic hyperuricaemia for conditions in which urate deposition has already occurred (including a history, or presence of, tophus and/or gouty arthritis). The detailed recommendations for the use of this product will be described in the Summary of Product Characteristics (SPC), to be made available after the medication receives marketing authorisation from the European Commission. Once the product receives its marketing authorisation and its price is agreed, Febuxostat will be marketed by Ipsen in France under the brand name Adenuric®. Outside France, the commercialisation of the product will be partnered. Jean-Luc Bélingard, Chairman and Chief Executive Officer of Ipsen, said, "We are very proud to receive this positive opinion for Adenuric® from the EMEA, and look forward to bringing this new molecule to market, pending European Commission approval. This innovative drug pioneers the first major treatment of gout for more than 40 years. It confirms Ipsen’s ability to continue to bring to the market important new treatment options for severely debilitating diseases.” About Adenuric® (febuxostat) Gout, a particularly painful type of arthritis, is the most frequent arthritis in men. It is caused by elevated levels of uric acid in the body: hyperuricaemia. Febuxostat, an oral, once-daily medication, is a novel non-purine, selective inhibitor of xanthine oxidase studied for its effects on lowering levels of serum uric acid (sUA) in patients with gout. Febuxostat is licensed to Ipsen for Europe from Teijin Pharma Limited, Tokyo. The EU submission includes two of the largest industry sponsored studies to date studying treatment of chronic gout patients. The goal of chronic gout treatment is per EULAR guidelines (European League Against Rheumatism) to reduce and maintain sUA levels below 6 mg/dL. Febuxostat demonstrated superior ability to lower and maintain in patients, serum uric acid at a level inferior to 6 mg/dl compared to conventionally used doses of allopurinol (febuxostat 80 and 120 mg: 51 & 63 % resp. vs. allopurinol: 22%). In addition, one phase III study showed that gout patients with mild to moderate renal impairment (serum creatinine >1.5 - =2.0 mg/dl) had response rate of 44 and 45 % respectively with febuxostat 80 and 120 mg.
