Description
Inclusion Criteria:
- Diagnosis of primary immune thrombocytopenia (ITP) by excluding other supervened causes of thrombocytopenia
- Patients with a platelet count <30,000/μL or a platelet count <50,000/μL with bleeding manifestations at the enrollment;
- Patients who did not achieve a sustained response to treatment with full-dose corticosteroids for a minimum duration of 4 weeks or who relapsed during steroid tapering or after its discontinuation;
- Willing and able to sign written informed consent.
Exclusion Criteria:
- Received chemotherapy or anticoagulants or other drugs affecting the platelet counts within 6 months before the screening visit;
- Secondary immune thrombocytopenia (e.g. patients with HIV, HCV, Helicobacter pylori infection, malignancy, or patients with confirmed autoimmune disease);
- Pregnancy or lactation;
- Pre-existing acute or chronic liver disease, or serum alanine aminotransferase (ALT) greater than 2 times the upper limit of normal (ULN);
- Current or recent (< 4 weeks prior to screening) clinically serious viral, bacterial, fungal, or parasitic infection;
- Have evidence of active tuberculosis (TB), or have previously had evidence of active TB and did not receive appropriate and documented treatment, or have had household contact with a person with active TB and did not receive appropriate and documented prophylaxis for TB;
- Patients who are deemed unsuitable for the study by the investigator.

Experimental: Teriflunomide
Oral Teriflunomide is given at a dose of 7 mg once daily with dose adjustments for 24 weeks.
Treatment was discontinued if a dose-limiting toxic effect occurred, rescue medication was used, or concomitant medication for immune thrombocytopenia was changed beyond the 10% level as defined above.
|
Starting dose of 7 mg once daily.
Dose adjustments were made throughout the study based on individual platelet counts.
