wonder if it means the MS market will have greater inertia than many expect.
Most cases of MS are slow moving - injury accumulating over years or even decades. The neuros are a conservative bunch - do no harm.
Then you have the concern that trials are neither big enough nor long enough for rare problems to surface.
On top of that, there is fear that combining a number of immuno-modifying drugs could have undesirable effects.
So I too think there will be considerable reserve in changing patients to newer drugs until they are failures on current therapy.
