Simponi is a “second-generation” anti-TNF-alpha drug whose approved indications are a subset of those for Remicade, Enbrel, and Humira. It was approved by the FDA for its initial indications in 2009 (#msg-37306991).
The commercial rights for Simponi are divided geographically in exactly the way as the commercial rights for Remicade: JNJ has the rights in most of the world (all countries except EU, Russia, Turkey, and Japan); MRK has the rights in the EU, Russia, and Turkey; and Mitsubishi has the rights in Japan.
In 1Q13, Simponi sold at a $1B annualized rate in JNJ’s territories and a $400M annualized rate in MRK’s territories. In other words, Simponi is a decent-selling drug, but its sales are tiny compared to Remicade, Enbrel, and Humira.
