Summary

This prospective, open-label, nonrandomized, multicenter clinical trial aims at comparing the efficacy and safety of combined use of TPO-RAs with low-dose anti-CD20 monoclonal antibody vs. the best available therapy（BAT）in adult immune thrombocytopenia with autoantibodies failed (due to intolerance or resistance) to first-line treatment.

Conditions

  • Immune Thrombocytopenia (ITP)
  • Autoantibodies
  • Evan Syndrome
  • Connective Tissue Diseases

Interventions

DRUG

Combined use of TPO-RAs with low-dose anti-CD20 antibody

Experimental: Combined use of TPO-RAs with low-dose anti-CD20 antibody The starting dose of eltrombopag is 50-75mg once daily. The starting dose of hetrombopag is 5.0-7.5mg once daily. The starting dose of avatrombopag is 20-40mg once daily. Prior to or within 2 weeks after initiation of TPO-RAs therapy, a single dose of Rituximab at 375mg/m2 or divided doses of Rituximab at 100mg once a week for 2-4 weeks, or a single dose of ortuzumab at 1000mg can be administered.. The dosage will be adjusted according to the results of laboratory examinations and patient tolerance.

DRUG

The best available therapy

The best available therapy except for combined use of TPO-RAs with low-dose anti-CD20 antibody includes but not limited to glucocorticoids, intravenous immunoglobulin, recombinant human thrombopoietin, TPO receptor agonists monotherapy, rituximab monotherapy, immunosuppressants, etc., and the researchers will adjust the treatment plan at any time according to the patient's condition.
