I have no layman's or professional experience with this drug.
I did some research and found that it is still in the clinical trial phase 3....Roche Pharmaceuticals. It's scheduled to go to some time in 2011.

It appears to be a HUGE trial as there are many locations around the world participating.
I hope this works for your hubby and he has pain free days!!
