To Evaluate the Safety and Efficacy of Teriflunomide in Patients With Relapsing Forms of Multiple Sclerosis

A Single Arm Phase IV Clinical Trial to Describe the Safety and Efficacy of Teriflunomide in Patients With Relapsing Forms of Multiple Sclerosis

Primary Objective:

To describe the safety of teriflunomide in patients with relapsing forms of multiple sclerosis.

Secondary Objective:

To describe the efficacy of teriflunomide in patients with relapsing forms of multiple sclerosis.

The study duration is one year; post treatment safety follow up visit will be conducted 4 weeks after the patient takes the last dose of teriflunomide

Inclusion criteria:

• Age of patients ≥ 18 years

• Signed written informed consent.

Exclusion criteria:

• Patients with hypersensitivity to teriflunomide, leflunomide, or to any excipients in the tablets.
• Liver function impairment or persisting elevations of serum glutamic pyruvic transaminase (SGPT/ALT), serum glutamic oxaloacetic transaminase (SGOT/AST), greater than two times the upper limit of normal (ULN) during screening visit.
• Known history of pre-existing acute or chronic liver disease.
• Patients with significantly (as per Investigator's discretion) impaired bone marrow function or significant anemia, leukopenia, or thrombocytopenia.
• Known history of severe immunodeficiency, acute or severe active infections.
