EDIT: Maybe cyclo is our new target for hope.
If you mean cyclosporin, it didn't do anything for me when I tried it many years ago, so I wouldn't consider it a contender for a genuine ME/CFS treatment. Since none of the immunosuppressants I tried, except for the first two tries of prednisone, had any effect on my symptoms, I didn't have any faith that rituximab was going to prove an effective treatment either, so I'm not surprised at the announcement.
I think research has to focus more on the effects of cytokines on our cells, rather than on trying to reduce cytokine production. One of the recent research findings was that our cytokine levels are only slightly elevated or even 'normal', even though the patients were suffering symptoms, so the problem seems to be other than elevated cytokines.
