9/16/2009 the FDA issued a notice stating that there have been 13 cases of PML confirmed with TY as a monotherapy, as of 9/8/09 with no cases before 12 infusions, and only 4 cases in the US. The average number of infusion for people with confirmed PML was 25 infusions.The risk MAY increase after 2 years."the current rate of PML in patients who have received at least 24 infusions ranges from 0.4 to 1.3 per 1,000 patients. At this time, the FDA is not requiring changes regarding PML to the Tysabri prescribing information or to the Tysabri risk management plan, called the TOUCH Prescribing Program."

A converstion of 0.4 -1.3 per 1,00 patients converted to a risk of 1...?
1 in 769 to 1 in 2,500 patientss.
Far from the days when it was 1 in 10,000 patients and getting rather close to 1 in 1,000 for after 2 years.
The FDA would change the label, not remove it from market again.
