The Combination of Teriflunomide and Danazol for Steroid-resistant/Relapse Immune Thrombocytopenia

Overview

To compare the efficacy and safety of teriflunomide plus danazol versus danazol in patients with steroid-resistant/relapse ITP

Description

This is a prospective, multicenter, randomized, controlled trial of 124 adult patients with steroid-resistant/relapse ITP in China. Patients were randomized to receive either experimental teriflunomide plus danazol or active comparator danazol monotherapy. Treatment was discontinued if very severe or life-threatening adverse events developed or at the patient's request.

Eligibility

Inclusion Criteria:

1. Primary immune thrombocytopenia (ITP) confirmed by excluding other supervened causes of thrombocytopenia;
2. 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;
3. Patients with a platelet count <30,000/μL or a platelet count <50,000/μL with bleeding manifestations at the enrollment;
4. Willing and able to sign written informed consent.

Exclusion Criteria:

1. Secondary immune thrombocytopenia (e.g. patients with HIV, HCV, Helicobacter pylori infection, or patients with confirmed autoimmune disease);
2. Active or a history of malignancy;
3. Pre-existing acute or chronic liver disease, or serum alanine aminotransferase (ALT) greater than two times the upper limit of normal (ULN);
4. Pregnancy or lactation;
5. Current or recent (< 4 weeks prior to screening) clinically serious viral, bacterial, fungal, or parasitic infection;
6. Active or chronic viral infection from hepatitis B virus (HBV), hepatitis C virus (HCV), or human immunodeficiency virus (HIV);
7. 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;
8. Have experienced a clinically significant thrombotic event within 24 weeks of screening or are on anticoagulants and in the opinion of the investigator are not well controlled;
9. Patients who are deemed unsuitable for the study by the investigator.
