Simvastatin

Just got this note from a SPMS friend:

Hi Ted glad to see you are doing good. Wonder if you heard of the medication Simvastatin which is use for lowering bad cholesterol in your blood ,this medication is used on patients with Secondary Progressive MS, high dosage 80mg, it seems to have good results for slowing down the progression , this of course is still clinical trial,but it's something. I am starting on it. Your opinion would be appreciated since we have the same type of MS .My neurologist agreed with me so I am excited about it. Best Regards.

Has anyone else out there had experience with Simvastatin for SPMS?
