taking the "short-term" view, Junius presented today and said that with the recent approval there are 14,000 patients that are now eligible for this drug in the US. So when the drug is available in less than two weeks, if most of those patients switch over to tdm-1 that puts the annual run rate at 14,000*$94,000 = $1.316B. Based on their royalty rate (3% for first $250M, 3.5% 250-400M, 4% 400-700M, 5% over 700M) that means royalty revenue should ramp up to $54M/year pretty quickly.
If you look at analyst estimates, for 2014 the revenue expectations run from a low of $13M to a high of $73M, with an average of $46M, it seems to me that some revisions should be forthcoming. Especially when you factor in additional milestone payments, approval for other than just the relapse patients, and approvals in other countries ramping up over the next several months. Unless I'm running the numbers wrong, 2014 revenue is going to be a higher than even the highest current analyst forecast.
