Details and patient eligibility

About

This is an open-label, randomized, multi-center, parallel-arm study to assess the safety and tolerability of a daily dose of Glatiramer Acetate (GA) 40 mg/mL three times a week (TIW) administered subcutaneously (SC) as compared to GA 20 mg/mL every day (QD) administered SC.

Full description

The study will comprise of a Core study and an Extension phase. During the Core study, subjects will be evaluated at study sites for 5 scheduled visits at Months: -1 (Screening), 0 (Baseline), 1, 2, and 4 (Termination/Early Termination). Subjects who complete all scheduled visits will have final procedures and assessments performed at the final visit (Month 4, Termination visit). Subjects who withdraw from the study before completing the 4 months evaluation period will have Early Termination (ET) procedures and assessments performed at their final visit.

During the Extension phase, all subjects will be offered to continue treatment with GA 40 mg/mL TIW. Subjects will be evaluated every 4 months until this dose strength is commercially available for the treatment of Relapsing-Remitting Multiple Sclerosis (RRMS) patients or until the development of this GA dose regimen is stopped by the Sponsor, the last visit of this phase will be called Termination/ET-Extension visit.

Enrollment: 209 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

3. Subjects with Neuromyelitis Optica (NMO).
4. Use of experimental or investigational drugs, and/or participation in drug clinical studies within the 6 months prior to screening.
5. Concomitant use of other disease modifying drug for MS ((Fingolimod (Gilenya®), dimethyl fumarate (Tecfidera®), Teriflunomide (Aubagio®) or intravenous immunoglobulin (IVIG)) within 6 months prior to screening

10. Pregnancy or breastfeeding.
11. Subjects with a clinically significant or unstable medical or surgical condition that would preclude safe and complete study participation, as determined by medical history, physical exams, ECG and abnormal laboratory tests. Such conditions may include hepatic, renal or metabolic diseases, systemic disease, acute infection, current malignancy or recent history (5 years) of malignancy, major psychiatric disorder, history of drug and/or alcohol abuse and allergies that could be detrimental according to the investigator's judgment.
12. Subjects who underwent endovascular treatment for Chronic Cerebrospinal Venous Insufficiency (CCSVI).
13. Employees of the clinical study site or any other individuals involved with the conduct of the study, or immediate family members of such individuals -
