Summary: Investigators at seven sites in the United States are recruiting at least 24 people with relapsing MS for a study of ublituximab (TG Therapeutics, Inc.), an experimental monoclonal antibody administered via intravenous infusion. At most, 100 people will be enrolled.
Rationale: Ublituximab is a new monoclonal antibody that binds to a molecule (CD20) on the surface of immune cells called B cells, and depletes them from circulation. B cells have several functions including making antibodies, and evidence suggests they play a role in immune-system mediated damage to brain and spinal cord tissues in MS. Other therapies targeting B cells (rituximab, ocrelizumab) have shown some benefit in clinical trials. Ublituximab binds to CD20 in a unique way, and thus may have greater B cell depletion capabilities than similar agents. Clinical trials are ongoing in people with blood cancer as well.
Eligibility and Details: Participants should be aged 18 to 55, have a diagnosis of relapsing MS, and have had more than one relapse in the previous two years. Further enrollment criteria are available from the contact below.
Participants are initially randomly assigned to receive either ublituximab or placebo infusions (infusions range from 1 to 4 hours). After 28 days, participants receiving placebo will receive ublituximab.
The primary outcomes being measured are the levels of B cell depletion, and the number of participants who experience adverse events. Secondary outcomes include monitoring relapses and MRI-detected disease activity.
