FLML may be higher on the list for improved interferon because it is further along and has comparator data vs pegylated interferon already..I don't own any but its now on my watch list. IF the data are compelling once released it could get licensed for big bucks
personally I am most intriqued by ZGEN's candidate because it is the only one I am aware of that doesn't just modify pK to achieve better profile, but rather focuses on target organ selectivity
then again if combination protease-polymerase inhibitors ever get off the ground the added antiviral effect of these newer interferons may get muted anyway
