July 26, 2026 updated by: Gregory Wu

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

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).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is an open label, randomized, multicenter collaborative research Phase 4 biomarker study, designed to generate hypotheses to better understand the MoA of cladribine tablets in RMS (to include RRMS or active secondary progressive MS). The study is designed to generate hypotheses regarding the impact and relevance of cladribine tablet activity in the CNS by assessing the cerebrospinal (CSF) levels of lymphocyte subsets, other immune cells, neuronal injury markers and soluble immunological markers in study participants with RMS before and during treatment with cladribine tablets, and the association of these CSF markers with corresponding blood markers and with clinical outcomes.
