Ixempra (ixabepilone; R-Pharm/Otsuka) is a lactam analog of epothilone B that binds to microtubules via tubulin. The binding of Ixempra to tubulin results in mitotic arrest of cells at G2-M followed by p53- and Bax-dependent apoptosis.
Datamonitor Healthcare does not expect Ixempra (ixabepilone; R-Pharm/Otsuka) revenues to grow significantly in the near future. Ixempra has not been a commercial success in breast cancer treatment, with peak revenues of only $117m in 2010 since its approval in 2007. Ixempra was acquired by R-Pharm from Bristol-Myers Squibb in 2015 and R-Pharm’s relative lack of oncology marketing experience and commercial resources could be detrimental to the drug’s growth. Ixempra faces competition from several late-phase candidates that may reach the market as early as 2016, and it could also face generic competition from 2018 after the expiration of key patents.
