Unconfirmed reports state that the case of PML was caught early and that the patient has already received plasmapheresis treatments and mefloquine, and is under treatment as an outpatient. The patient had a prior history of treatment with interferons, glatiramir acetate and methotrexate. It is unknown at this time how long the patient was off those other drugs.
More forthcoming as it becomes available.
