SPMS trials

Any SPMSers out there on a drug trial? I finally got on Cladriplas @ Barts London but my NfL not high enough to get the cladribine treatment. Missed out on Campath (Alemtuzemab) trial in 2012 when still diagnosed RR because I was deemed too mobility impaired even though I could walk 500m unaided, albeit like I was drunk. Now I walk 20m on crutches. Someone please give me a fucking break!
