From 1Q01 CC:

Company believes its ETi's are the most potent and selective of all in class; that the selective ET-As will be most therapeutic; and that leaving ET-B alone is beneficial by allowing more vasodilation. As opposed to Actelion (class 3,4), txb's ETi's are being given to class 2, 3 and 4 pts. Once-a-day dosing.

2nd gen is *much* more selective for ET-A and more potent, (possibly longer-acting?). Sitaxsentan (1st gen) is once-a-day. Both are into the clinic in the ICOS-TXB JV, in PHT first (2nd gen will either be tested in follow on PI with serial doing, and then in CHF or PHT in a P2 maybe beginning 1Q02). Not letting up on 1st gen, clearly going to take it as far as it can go. Have been encouraged by the Actelion results (hemodynamics), and weren't surprised by the lack of clinical benefits given the acute setting and admin on top of nitro and other agents. Estimate of Argatroban sales in '01 are $16m - $20m. Expecting much more as time goes by and GSK ploughs the field.
