$11.6M that eisai ordered for prelaunch inventory implies strong launch
That's arena revenue. divide that by 31% to get eisai revenue ($37M). divide that by $200/script = 184k scripts. according to annual report, Eisai holds ~7weeks of inventory. so that's 14k scripts per week (or 10% of the phen scripts per week). But wait, but that $200/script assumes no coupon/sample, if the weight avg of is $100/script, that's 28k scripts per week and 20% of phen scripts.
