CoTherix
CoTherix was a biopharmaceutical company located in South San Francisco, California. CoTherix focused on licensing, developing, and commercializing therapeutic products for the treatment of cardiopulmonary and other chronic diseases. The company, formerly known as Exhale Therapeutics, Inc., was founded in February 2000 by Gerard Turino, MD, a past president of the American Thoracic Society, and Jerome Cantor, MD, a pulmonary pathologist.
CoTherix's commercial product was "Ventavis (Iloprost)", an inhaled therapy for pulmonary artery hypertension (PAH). It was approved by the United States Food and Drug Administration in December 2004, two months after the company's initial public offering of 5 million shares of common stock.
Fasudil, Tracleer, Asahi and Actelion
Asahi developed fasudil and entered into a licensing and development agreement with CoTherix in July 2006 to pursue regulatory approval and commercialization in the United States and Europe based on their prior track record in this area. In November 2006, CoTherix and Actelion signed a merger plan, which was subsequently announced publicly; this followed the initiation of negotiations in August 2006. In January 2007, Actelion completed acquisition of all CoTherix stock, and summarily informed Asahi that work on fasudil would be terminated. Now, Actelion had a competitor blockbuster drug on the market, bosentan (Tracleer). Asashi claimed that Actelion's acquisition of CoTherix was directly aimed at removing fasudil as a competitor therapeutic, which it effectively did. Asahi pursued damages against CoTherix and Actelion initially through arbitration of a breach of contract claim, which netted them US$91 million, then in a jury trial, which resulted in an award of US$580 million in compensatory and punitive damages. This case has served as an exemplar of the notion that a company's contractual obligations persist after that company's acquisition.
