New treatment (experimental?) Rystiggo

rozanolixizumab (brand name RYSTIGGO)
Has anyone had any experience with this?
I’m not questioning the validity of the trial, simply any after effects and risks and anything enlightening about this treatment. It’s a series of 6 weekly injections.
My neurologist has prescribed this and I’m his “beta tester” I do have a lot of faith and confidence in him and am quite excited to get this going. All mandated vaccines have been administered. Thanks in advance for any thoughts or advice
