Default FDA updated the Tysabri label today
Applicable part of the label

"In patients treated with TYSABRI, the risk of developing PML increases with longer treatment duration, and for patients treated for 24 to 36 months is generally similar to the rates seen in clinical trials."

Guess they see the rate as about 1 in 1000 for those between 24 and 36 months.
