ESRX is opening up tx to all HCV patients, even early stage, so it's fair to assume penetration will be somewhat higher than uptake under more restrictive plans and PBOs. so i think it's fair to increase the 8% assumption to 10% of total Rx
if ABBV gets 90% of gen-1 patients under the ESRX plan (allocating 10% to GILD for pts with contraindications to v-pak - consevative IMO), and 5% (180 nrx vs 3600 nrx) of the non-ESRX, that amounts to .9x.1 + .05x.9 = 13.5% market share. The 5% non-ESRX is bound to rise given the early stage of the launch but 13.5% of a market this size is already real money
