About this study
Official title: A Phase Ia Study to the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of IASO-782 in Patient With Autoimmune Hematological Diseases (Autoimmune Thrombocytopenia and Warm Antibody Type Autoimmune Hemolytic Anemia)
This study is a randomized, double-blinded, and placebo-controlled phase Ia clinical study in subjects with autoimmune hematological diseases. The study is designed to assess the safety and tolerability of IASO-782 for the treatment of autoimmune haematological diseases (ITP and wAIHA).
Read the detailed description
This study is a single-dose escalation study in subjects with autoimmune hematological diseases. The study is designed to enroll subjects with autoimmune thrombocytopenia and warm antibody type immune haemolytic anaemia (ITP and wAIHA).
Referred to the clinical pharmacological study and development experience of similar drugs, one or more dose regimens will be determined for the use in Phase 1b clinical trials.
This study will evaluate the safety and preliminary dose range of IASO-782 in subjects with autoimmune hematologic diseases (ITP and wAIHA) at the following dose levels:6mg/kg and 10mg/kg.
- Being tested
- IASO-782 injection, placebo
- Medical subject headings
- Purpura, Thrombocytopenic, Idiopathic
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
IASO-782 injectionDrug
Each subject will be given only one dose of IASO-782. Subjects should avoid strenuous exercise within 48 h before administration and remain seated or semi-recumbent (except for necessary activities) for 4 h after administration. IASO-782 solution for injection or placebo was diluted in 0.9% sodium chloride injection (corresponding to the dose administered according to the body weight at baseline and the dose group) with a total volume of 250 mL, administered as a single intravenous drip at a drip rate recommended by the drug manual on the day of administration, The infusion time is about 90 minutes (± 15 minutes).
placeboDrug
Each subject will be given one dose of placebo. Subjects should avoid strenuous exercise within 48 h before administration and remain seated or semi-recumbent (except for necessary activities) for 4 h after administration. IASO-782 solution for injection or placebo was diluted in 0.9% sodium chloride injection (corresponding to the dose administered according to the body weight at baseline and the dose group) with a total volume of 250 mL, administered as a single intravenous drip at a drip rate recommended by the drug manual on the day of administration, The infusion time is about 90 minutes (± 15 minutes).

The safety and tolerability of IASO-782 will be assessed primarily by summarizing treatment-emergent AEs and SAEs.
Measured: up to 12 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing IASO-782 injection in people with Autoimmune Thrombocytopenia and Warm Autoimmune Haemolytic Anaemia, run by Shanghai IASO Biotechnology Co., Ltd at 2 sites 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 14 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 29 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 Changpu Cao (+86-13584069411, changpu.cao@iasobio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of participants with adverse events as assessed by CTCAE v5.0 (time frame: up to 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 May 2026.
