"2. Slows down the progression of physical disability.
People who were treated with TYSABRI were 42% less likely to develop worsening physical disability — 29% of people who received a placebo had their physical disability worsen, versus only 17% of people who were treated with TYSABRI.
Of the 627 people who took TYSABRI in the 2-year study, more than 8 out of 10 had no physical disability progression."

Harryz am I wrong or just clueless? I'm new to this MS research and can use all the help I can get

I guess a lot depends on how you interpret this kind of information.
The numbers they quote are compared to placebo patients. 29% of these patients had disability progression which means 71% of the placebo patients did not have any progression. The very nature of MS, being remitting and relapsing in most cases, makes it very difficult to determine just how well any kind of medication is working.
They quoted that 8 out of 10 patients who used Tysabri did not have progression for 2 years. But using their numbers, one could state that 7 of 10 placebo patients did not suffer progression either. And for MS, two years of data is a very short period of time.
After my wife suffered her first attack at age 21, she went 20 years without disease progression. She took nothing...there was nothing to take. Had she used any kind of mediciation, the manufacturer could claim that their drug delayed progression for 20 years.
The CRAB drug makers all claimed that their drugs reduced attacks by about 30% and that MS patients should take them. Huge cost, very minimal benefit and a lot of side effects. They brought out their fancy charts at conferences and "showed" everyone that the drugs really worked. We now know that they really didn't.
Tysabri shakes a MS patient's immune system up hugely. It's no wonder the patient has some kind of reaction. But like most MS patients, some Tysabri users benefit a fair amount, some stay about the same and others become worse with the severe side effects. Are the numbers better than the CRAB drugs...yep..but those numbers were lousy to begin with.
