I want to point out a significant detail. CD4 lev

What it does is create more of an opportunity for the JV virus (which is present in 70 to 90% of people worldwide) to get out of control of the immune system which can result in PML.
If CD 4 levels drop below 250 then the answer is just to stop taking the drug and let CD 4 levels recover.
One other interesting caveat is that there are very few treatments for PML but, one recommended treatment is prescribing Ziagen.
A close examination of the Xenoport deal with $50 million in upfront payments and a quarter billion in backends will show you that that particular drug is a member of the Fumaric Acid Esters which also must be monitored for PML risk.
That's why I frequently set that as a relevant price comparison rather than "Prurisol is currently worth 10 billion."
(This is one of those "unanswered questions" I have eluded to that is probably impacting share price. )
The Prurisol results are do very soon and we will all get our answers.
That's why I'm adamant t's not "naked shorts" , it's trial funding and unanswered questions.
Good Prurisol results will solve both at once if they are good and show a dose response curve that's effective while keeping CD 4 above 250.
