About this study
Official title: A Randomized, Open-label Study To Compare The Efficacy And Safety Of Anti-CD38 Monoclonal Antibody Versus Rituximab in ITP Patients Who Failed or Relapsed After Glucocorticoid Therapy
This randomized, open-label study aim to compare the efficacy and safety of Daratumumab (anti-CD38 monoclonal antibody) with rituximab in ITP patients.This study will be conducted in ITP patients who had not responded to or had relapsed after previous glucocorticoid treatment.
Read the detailed description
Immune thrombocytopenia (ITP) is an organ-specific autoimmune disease, which is characterized by decreased platelet count and skin and mucosal bleeding. ITP is a kind of disease with increased platelet destruction and impaired platelet production caused by autoimmunity. Conventional treatment of adult ITP includes first-line glucocorticoid and immunoglobulin therapy, second line TPO and TPO receptor agonist, splenectomy and other immunosuppressive treatments (such as rituximab, vincristine, azathioprine, etc.). ITP is one of the most common hemorrhagic diseases. At present, the treatment response of ITP is not good, and a considerable number of patients need drug maintenance treatment, which seriously affects the quality of life of patients and increases the economic burden of patients. Therefore, there is still a lack of effective treatment for adult ITP, especially for recurrent and refractory ITP patients, which is one of the problems that have attracted more attention and need to be solved urgently.
The main pathogenesis of ITP is the loss of platelet autoantigen immune tolerance, which leads to abnormal activation of humoral and cellular immunity. It is characterized by antibody mediated platelet destruction and insufficient platelet production by megakaryocytes. The residual long-term autoreactive plasma cells may be a source of therapeutic resistance to autoimmune cytopenia. Antiplatelet specific plasma cells have been detected in the spleen of patients with rituximab refractory ITP. Therefore, the strategy of simply eliminating B cells may not work, because LLPC will continue to produce pathogenic antibodies. In view of this, anti-CD38 monoclonal antibody can eliminate LLPC, thereby profoundly reducing the production of pathogenic antibodies and achieving good efficacy. Some patients have been treated with this Daratumumab (anti-CD38 monoclonal antibody) in the past, with good efficacy and safety. Therefore, the investigator planned to conduct a clinical study to evaluate the safety and efficacy of Daratumumab (anti-CD38 monoclonal antibody) versus rituximab in relapsed adult patients with primary immune thrombocytopenia, in order to provide more treatment options for patients with ITP.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Rituximab and Daratumumab in people with Immune Thrombocytopenia and Treatment, run by Institute of Hematology & Blood Diseases Hospital, China at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 11 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Lei Zhang, MD (+8613502118379, zhanglei1@ihcams.ac.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall response rate at week 12 (time frame: 12 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2026.
