Brief summary
To compare the efficacy and safety of teriflunomide plus danazol versus danazol in patients with steroid-resistant/relapse ITP
Detailed 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.
Interventions
Starting dose of 7 mg once daily. Dose adjustments are made throughout the study based on individual platelet counts.
200 mg twice daily.

Intervention model description
Patients were randomly assigned at a 1:1 ratio to receive teriflunomide plus danazol or danazol. Each group requires 62 patients (considering a 10% drop-off).
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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sustained response | From the start of study treatment (Day 1) to the end of week 24 | Platelet count over 30,000/μL and at least a 2-fold increase of the baseline count in the absence of bleeding and rescue therapy for at least four of the six visits between weeks 19 and 24. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to response | From the start of study treatment (Day 1) to the end of week 24 | The time from treatment initiation to achieve a CR or a R. |
| Duration of response | From the start of study treatment (Day 1) to the end of week 24 | The time from the achievement of a complete response or a partial response to the loss of response. |
| Initial response | From the start of study treatment (Day 1) up to week 4 of treatment | The number of participants with achievement of CR or R at 4 weeks. |
| Overall response | From the start of study treatment (Day 1) to the end of week 24 | Complete response (CR) was defined as platelet count over 100,000/μL and absence of bleeding. Response (R) was defined as platelet count over 30,000/μL and at least a 2-fold increase of the baseline count and absence of bleeding. |
| Adverse events | From the start of study treatment (Day 1) to the end of week 24 | Adverse events (AEs) were reported and graded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. |
| Health-related quality of life (HRQoL) | From the start of study treatment (Day 1) to the end of week 24 | ITP-PAQ was used to assess the Health-Related Quality of Life (HRQoL) before and after treatment. |
| Bleeding events | From the start of study treatment (Day 1) to the end of week 24 | Clinically significant bleeding was assessed using the World Health Organization (WHO) bleeding scale. |
