Cladribine Tablets: Collaborative Study to Evaluate Impact On Central Nervous System Biomarkers in Multiple Sclerosis

CompletedPhase 4

Sponsor: Gregory Wu

Conditions: Multiple Sclerosis, Multiple Sclerosis, Relapsing-Remitting

Interventions: Cladribine

Countries: United States

The purpose of this study is to better understand the mechanism of action (MoA) of cladribine tablets by exploring the effect on central nervous system (CNS) and blood biomarkers relevant in the relapsing forms of multiple sclerosis (RMS; to include relapsing-remitting MS \[RRMS\] or active secondary progressive MS).
