Frexalimab Trial

I have an opportunity to join a Frexalimab trial where 100% of participants get the real medicine. They're testing subcutaneous vs infusion.

I was on Copaxone for 12 years and stable until a severe relapse. I then switched to Kesimpta 2 years ago but possibly having another (less severe) relapse right now.

Currently waiting for my Octave score and will do an MRI soon. But I was wondering if anyone here has personally experienced Frexalimab.
