About this study
Official title: A Single-arm, Open-label Clinical Study Evaluating the Safety and Efficacy of Daratumumab in Elderly Patients With Primary Immune Thrombocytopenia
To evaluate the safety and efficacy of Anti-CD38 Antibody in the treatment of elderly patients with primary immune thrombocytopenia in patients who have failed multiple 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 elderly are at a higher risk of developing immune thrombocytopenia, and they often have cardiovascular risk factors. They usually cannot tolerate treatment regimens such as hormones and immunosuppressants.
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. However, targeting LLPC becomes a new strategy to treat autoimmune diseases.
Daratumumab, a kind of anti-CD38 antibody, is a new type of monoclonal antibody targeting CD38. It targets plasma cells and has carried out some clinical studies in multiple myeloma, with good therapeutic effects. In addition, the clinical trials of daratumumab in the treatment of autoimmune diseases, including membranous nephropathy, systemic lupus erythematosus (SLE) and ITP, are also being carried out simultaneously. The investigators assume that autologous reaction LLPC may be the cause of treatment failure in some ITP patients. Therefore, the use of CD38 monoclonal antibody to clear long-term surviving plasma cells in ITP patients may be a new strategy for treating ITP patients.Our hospital has conducted and completed a clinical trial of daratumumab for the treatment of adult ITP. The dosage was 16mg/kg/w for a total of 8 weeks. The results showed that for refractory patients who had previously received multiple lines of treatment with poor efficacy, daratumumab could rapidly increase platelet counts. The median onset time was about 1 week. At 24 weeks of follow-up, the effective rate was approximately 60%, and no serious adverse events occurred. The efficacy and safety were confirmed, but the number of elderly patients included was relatively small.
Therefore, the investigators designed this clinical trial to evaluate the safety and efficacy of daratumumab in the treatment of elderly patients with immune thrombocytopenia in patients who failed multiple treatment.

What participants receive

Daratumumab InjectionDrug
This study adopts a prospective, single arm, open design method. Thirty subjects were enrolled in the study and were treated with CD38 monoclonal antibody (Daratumumab 16mg/kg/w) for 4 weeks.
The first stage is the main research stage (d1-w4), which is the core treatment period. The subjects will receive intravenous infusion of 16mg/kg Daratumumab once a week for 4 weeks to observe the safety and efficacy during treatment.
The second stage (w5-w24) is the stage of withdrawal from the visit, mainly to observe the safety and continuous efficacy of Daratumumab after treatment.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Daratumumab Injection 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 25 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 14 Jul 2025. 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 Ting Sun, MD (+8615822339131, sunting@ihcams.ac.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Adverse events of Anti-CD38 antibody treatment (time frame: 24 weeks). The study lists 2 primary outcomes in all. 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 14 Jul 2025.
