Øystein Fluge
Øystein Fluge, MD, is the Senior Consultant supervising the ME/CFS research group at the Department of Oncology and Medical Physics at the University of Bergen, Haukeland University Hospital, Bergen, Norway.[1] He works with Professor Olav Mella in the Norwegian Rituximab and cyclophosphamide trials employing the depletion of B cell lymphocytes in ME/CFS patients.
Dr. Fluge is a member of the Working Group which offers their expertise and resources to the ME/CFS Collaborative Research Center at Stanford University.[2]
Rituximab work in ME/CFS[edit | edit source]
Øystein Fluge's and Olav Mella's discovery was found by accident, in that three ME/CFS patients who had B-cell lymphoma improved remarkably following treatment with Rituximab. Not only had their lymphomas improved, but all symptoms of their ME/CFS diminished with the treatment. The positive responses were delayed for up to 6-12 weeks, despite their B cells being eliminated by the drug in 2 weeks. Since that accidental discovery, a larger study has been undertaken. Initial reports were promising in that there is a positive response in 67% of the patients receiving Rituximab vs a 13% improvement in the placebo group. After the effects wore off, there was a decline in the numbers who responded to the second and subsequent infusions.[3] The clinical trial, named RituxME, was a multicenter, phase III study. It was randomized, double-blind and placebo controlled, with 152 participants, of which half will receive treatments with rituximab and the other half will be treated with placebo (saline).[4]
On Nov 21, 2017, Drs. Øystein Fluge and Olav Mella announced that their Rituximab trial had failed. They stated that they would focus their efforts on attempting to identify a subgroup of ME/CFS patients with an immune profile that would be responsive to Rituximab. The Drs. will publish a paper next year with the specifics of the failed trial.[5]
The discovery of ME/CFS patients responding positively to an autoimmunity drug has radically changed how many have viewed ME/CFS, to the point that Bjørn Guldvog, the Deputy Director General of Norwegian Directorate of Health, has apologized for the way in which ME patients in Norway have been treated: "I think that we have not cared for people with ME to a great enough extent. I think it is correct to say that we have not established proper health care services for these people, and I regret that." The European ME Alliance believes that such a public apology from a governmental health agency has never occurred before.[6]
In 2015, a second clinical trial for ME/CFS by the same group headed by Fluge and Mella, was started using the chemotherapy drug, cyclophosphamide. Called CycloME part A, this study will involve 40 patients with moderate and severe ME/CFS and will be ongoing until January 2017. If the results indicate a clinically relevant response, i.e., an improvement in symptoms, in a minimum of 40% of the patients, the trial will move into CycloME part B and may be extended to include patients with very severe ME.[7]

The study abstract states: "The association of autoantibodies with immune markers suggests that they activate B and T cells expressing β adrenergic and M acetylcholine receptors. Dysregulation of acetylcholine and adrenergic signalling could also explain various clinical symptoms of CFS."[10]
