Ciclesonide ( Byk Gulden).
Ciclesonide, a non-halogenated inhaled corticosteroid with anti-inflammatory activity, is under development by Byk Gulden, Aventis and Teijin as a potential treatment for asthma [213439]. It was also being developed by Byk Gulden for chronic obstructive pulmonary disease (COPD), but no development had been reported for this indication since 1999; however, Teijin was carrying out clinical trials in this indication at the end of 2000. During 2000, Byk Gulden was carrying out phase III trials in the US and Europe and in March 2001, results were expected in the third quarter of 2001 [312399], [383726], [423659]. Two inhalant formulations (multidose powder and propellant filled) and a nasal formulation of ciclesonide are being developed by Byk Gulden for the treatment of asthma and seasonal allergic rhinitis, respectively [337147]. The compound is formulated for once-daily dosing and demonstrated good efficacy without corticosteroid-associated systemic side effects [409257]. In January 2001, Byk Gulden expected launch of a CFC-free multidose inhaler formulation in 2003 [395596]; in March 1999, launch of a nasal formulation was expected in 2004 and a multidose powder inhaler in 2005 [337147]. By September 2001, the compound was in phase III trials in the US for asthma, with a potential US launch anticipated by Aventis in 2004 [423465]. In November 2001, Aventis expected to submit an NDA to the FDA in 2003 [428057]. Teijin, which has a development and licensing agreement with Byk Gulden for the treatment of asthma and COPD in Japan, commenced phase I trials of ciclesonide in Japan in spring 1999, had completed these during 2000, and began phase II trials by September of that year [383726]. An NDA is expected to befiled in Japan in 2003. In October 2000 and April 2001, Merrill Lynch predicted peak sales of Euro400 million in 2007, with sales of Euro5 million in 2002, rising to Euro150 million in 2004 [395562], [420574]. Deutsche Bank predicted in August 2001, that sales of the product would reach Euro70 million in 2004, rising to Euro150 million in 2005 [420814].
