Tysabri numbers

Color me happy.

Biogen presented their earnings today and part of that was Tysabri numbers.

Background: Biogen is Elan's marketing partner for Tysabri. In late July it was disclosed that 2 patients in Europe had developed PML -- which Tysabri has a black-box label warning for, estimated at 1 in a 1000 chances of contracting.

We went from 31,800 patients at the end of June to 35,500 patients at the end of September. (#s are totals-- 600 of those are in clinical trials). So we gained 11% patients, in a quarter where we lost over half the market cap due to PML fears.

As usual, most PR coverage was negative - even false. For example, Lisa LaMotta, a Forbes Online columnist, wrote the following (as of 10/21/08 at 9:40 PM it still says this -- I fully expect by tomorrow it will be "updated" / edited ... AFTER the immediate damage has been done.

"....Biogen Idec reported earnings that beat expectations mostly due to the sale of its two multiple sclerosis drugs, but investors were disappointed by a slight slowdown from the second quarter in the number of patients taking one of them...
...As of the end of September, more than 35,500 patients were on Tysabri,the mulitple sclerosis drug in question, down from 31,800 at the end of the second quarter...."

1) slight slowdown? The RATE OF GROWTH slowed down. but the number of patients increased!
2) use a spell checker if you are going to call yourself a Forbes journalist!!! (sorry, catty, I know)
3) First time I've heard of 35K being lower than 31K.

Almost sounds like she'd written the hit piece first -- intending simply to fill in the expected bad numbers, doesn't it?

Next -- PML risk; rated at 1:1000.
We have 35,000 on therapy now, and 3,000 from before 2006, with a total of 4 patients contracting PML. It sounds to me more like 1 : 10,000.

Elan is around $9 right now, and SO UNDERVALUED by Mr. Market that is scary. Tysabri sales are increasing and we officially hit blockbuster status -- sales of $1B (granted -- projecting forward revenues).
Before the PML scare in July just on Tysabri Elan was valued around $20. (don't get me started on the Alzheimer's drug AAB-001 and its potential -- a massive Phase III trial nearly a year already underway from it's first dosed patient and a statistically significant showing in a subgroup of gene carriers).

It will probably be one more quarter before the market shows Elan any love -- and coincidentally the next quarter which should show a large increase in quarter-over-quarter sales of Tysabri.
So I would not be surprised if Elan bounced between $8 and $11 over the next three months -- but by February of 2009 I fully expect to see Elan at about $14 - 17; a rather sweet return of 50% or so. If an interim look at AAB-001 comes in positive, then the rocketship ignites.
