TOPIK Study: A Study to Report Progressive Multifocal Leukoencephalopathy and Other Serious Opportunistic Infections in Natalizumab Treated Participants
June 6, 2023 updated by: Biogen
Long-term Surveillance of Patients With Multiple Sclerosis to Report Progressive Multifocal Leukoencephalopathy and Other Serious Opportunistic Infections Among Patients Treated With Natalizumab
The primary objective of the study is to estimate the incidence of progressive multifocal leukoencephalopathy (PML) and serious adverse events (SAEs) of other opportunistic infections (OIs) among all participants taking natalizumab.
The secondary objectives of the study are to estimate the incidence of SAEs, to estimate the incidence of SAEs among participant subgroups defined by demographic and clinical factors (age, gender, duration of treatment, pregnancy, breastfeeding), to characterize and estimate incidences of malignancies, hypersensitivity reactions and John Cunningham Virus (JCV) positivity among all participants taking natalizumab, and to count and describe pregnancies and breastfeeding among participants previously exposed to natalizumab.
