Press Release: FDA Issues Third Approvable Letter for Thelin
FDA Issues Third Approvable Letter for Thelin Houston, TX â€“ June 15, 2007 â€“ Encysive Pharmaceuticals today announced that the Company has received its third approvable letter from the U.S. Food and Drug Administration (FDA) for THELIN(tm) (sitaxsentan sodium), which is under review for the treatment of pulmonary arterial hypertension (PAH). In this third approvable letter, the FDA stated that Encysive's development program for THELIN did not demonstrate the evidence of effectiveness needed for approval. The FDA did note, however, that the THELIN development program provides some evidence that THELIN improves exercise tolerance in PAH. The FDA encouraged the Company to conduct an additional study to demonstrate the drug's effectiveness in exercise capacity as measured by change in six-minute walk distance. "We believe we adequately addressed the issue raised by the FDA in the second approvable letter and we are deeply disappointed in their decision. Encysive remains committed to THELIN in Europe, Australia and Canada, where it has been approved for sale," commented Bruce Given, M.D., President and CEO of Encysive Pharmaceuticals Inc. "We greatly appreciate the PAH patients and clinicians in the U.S. and worldwide who have been so supportive of the THELIN development program," he added. Encysive plans to discuss the most recent approvable letter with the FDA as soon as possible to determine the appropriate path forward. The Company may be required to make significant reductions in its infrastructure and workforce in the U.S. as a result of the decision by FDA. The Company is reviewing its strategic alternatives and intends to communicate its plans at a later date.
