Official title
A Randomized, Rater-Blinded Study to Explore the Effect of Mefloquine in Subjects With Progressive Multifocal Leukoencephalopathy (PML)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary objective of the study was to explore whether mefloquine can delay or stop progression of progressive multifocal leukoencephalopathy (PML) as measured by JC virus (human polyomavirus or JCV) deoxyribonucleic acid (DNA) levels in cerebrospinal fluid (CSF). The secondary objective of the study was to explore whether mefloquine can delay or stop progression of PML based on neurological deterioration, magnetic resonance imaging (MRI) measures of brain lesion evolution or the formation of new lesions, and mortality.
