E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Relapsing multiple sclerosis (RMS) |
|
E.1.1.1 | Medical condition in easily understood language |
In RMS, the central nervous system, which includes the brain and spinal cord, becomes damaged. MS causes the immune system to attack the myelin, which is the insulation protecting the nerves. |

CSF BIOMARKER SUBSTUDY ASSOCIATED WITH A PHASE III MULTICENTER, RANDOMIZED, DOUBLE BLIND, DOUBLE-DUMMY, PARALLEL-GROUP STUDY (GN42272) TO EVALUATE THE EFFICACY AND SAFETY OF FENEBRUTINIB COMPARED WITH TERIFLUNOMIDE IN ADULT PATIENTS WITH RELAPSING MULTIPLE SCLEROSIS
Protocol Number: GN42272 Protocol Version: 2 Protocol Date: 19-DEC-2020
Primary CSF Biomarker Objective The primary CSF biomarker objective for this substudy is to evaluate the impact of fenebrutinib compared with teriflunomide treatment on a potential progression biomarker related to neuronal injury, as well as specific biomarkers related to B cells and myeloid lineage cells on the basis of the following endpoints: -Changes in NfL -Changes in B-cell activity, including IgG oligoclonal bands (OCBs) and IgG index -Changes in myeloid lineage cells including CCL4
