title: Sitaxsentan (ICOS-Texas Biotechnology).
abstract: ICOS-Texas Biotechnology is developing the endothelin A (ETA) receptor antagonist, sitaxsentan, for the potential treatment of pulmonary hypertension, congestive heart failure (CHF), chronic obstructive pulmonary disease and subarachnoid hemorrhage [205713], [302200]. The compound is in phase IIa trials as an iv formulation for CHF and has completed phase I safety trials as an oral formulation [272071]. Phase II/III trials for pulmonary hypertension are planned for the first quarter of 2001 [3945711]. In June 2000, ICOS and Texas Biotechnology established a joint venture to develop and commercialize endothelin antagonists [370007]. US-05591761 was issued to Texas in January 1997, covering TBC-11251 and several related isomers [2309301.
