Thats interesting. I know Tadalafil for its other label (Cials) should go off patent earlier. But for Adcirca I thought it was approved only in the 40mg dose?
I still have some UTHR but don't follow it quite as closely. I think they have upside (near term) if the inhaled is picking up as fast as Martine indicated a while back. Also I think their oral program has a high probability of success. In general though PAH has become way too crowded IMO.
Knocking out the Adcirca CoM patent, which expires in Nov 2017, won’t provide much economic benefit to the P-IV challenger. That’s because orphan drug exclusivity in PAH, which can’t be overturned by a P-IV challenge, runs until Apr 2016.
