About this study
Official title: A Phase II, Single Center, Open-label Trial to Determine the Safety and Efficacy of Zanubrutinib in Refractory/Relapsed Autoimmune Hemolytic
The sample size of this study is calculated based on Simon's two-stage design. The first stage of the study enrolled a cohort of 12 patients. If after 12 weeks at least 6 patients achieved a response, then enrollment was expanded to a total of 26 patients. The null hypothesis was unaccepted if more than 14 of 26 patients achieved the response. Accounting for a 20% dropout rate, the estimated final sample size was 33 patients.
- Being tested
- Zanubrutinib
- Medical subject headings
- Anemia, Hemolytic, Autoimmune
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ZanubrutinibDrug
Zanubrutinib was specifically designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity.
| Study group | Role | What they receive |
|---|---|---|
| Zanubrutinib | Experimental | Each recruited subject will accept Zanubrutinib treatment. Receives: Drug: Zanubrutinib |
What is being measured
The primary outcome is the main question the study is designed to answer.
Overall response rate
The percentage of patients achieved complete response, complete response with incomplete hemolysis recovery, and partial response.
Measured: within 12 weeks
Secondary outcomes (2)
Incidence of adverse events and severe adverse events
Measured: within 24 weeks
Relapse free survival rate
Measured: within 48 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Zanubrutinib in people with Refractory/Relapsed Autoimmune Hemolytic Anemia, 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 6 inclusion and 17 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: status not confirmed, as of the sponsor's last update on 29 Nov 2023. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Weiwang Li, PhD (15332132036, liweiwang@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 (time frame: within 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 29 Nov 2023; AzTrials last refreshed its copy on 8 Nov 2026.
