What is being measured
The primary outcome is the main question the study is designed to answer.
Adverse Events (AE) after CT1390B infusion
An assessment of severity grade will be made according to the National Cancer Institute Common Terminology Criteria
Measured: 12 months after CT1390B infusion
Dose-limiting toxicity (DLT)
The DLT is evaluated as the proportion of patients who experienced adverse events related to CT1390B that meet the criteria for DLT events after the first infusion
Measured: Up to 28 days after CAR-T cells infusion
MTD and/or dose range
Evaluate Dose limited toxicity and recommended dosage range after CT1390B infusion
Measured: Up to 28 days after CAR-T cells infusion
Secondary outcomes (11)
Complete response (CR), complete response with partial hematologic recovery (CRh),and complete response with incomplete hematologic recovery (CRi)
Performed according to the Technical Guidelines for Clinical Development of New Drugs for Acute Myeloid Leukemia and ELN 2022 Criteria for AML defined as achieving CR,CRh and CRi
Measured: 12 months after CT1390B infusion
Morphologic leukemia-free status (MLFS) and partial response (PR).
Performed according to the Technical Guidelines for Clinical Development of New Drugs for Acute Myeloid Leukemia and ELN 2022 Criteria for AML defined of Achieve MLFS and PR
Measured: 12 months after CT1390B infusion
Proportion of patients undergoing stem cell transplantation following CAR-T therapy.
Measured: 12 months after CT1390B infusion
Duration of response (DOR)
Participants achieving CR/CRi/CRh will be included in the analysis set for DOR. DOR is defined as the time from the date of confirmed response until the date of disease relapse or death from any cause, whichever occurs first
Measured: 12 months after CT1390B infusion
Event-free survival (EFS)
Defined as the time from the date of receiving the infusion to the date of treatment failure (failure to achieve CR/CRh/CRi/MLFS/PR after both efficacy assessments), or relapse (hematologic relapse or extramedullary relapse after CR/CRh/CRi), or death from any cause, whichever occurs first. When an EFS event was "Ineffective Therapy", the primary analysis of EFS was performed on a 1-day basis (ie, time to treatment received as the event). For a more comprehensive assessment, sensitivity analyses could be performed using the actual date of treatment failure, end of treatment, or start of next-line anti-leukemia therapy as the end of EFS for treatment failure, respectively
Measured: 12 months after CT1390B infusion
Overall survival (OS)
Defined as the time from the date of receiving the infusion to the date of death from any cause
Measured: 12 months after CT1390B infusion
Minimal Residual Disease (MRD) Negative Rate
tested in all participants who achieved CR/CRh/CRi. MRD negativity was defined as abnormal cells detected by the MFC method accounting for < 0.1% of CD45-positive cells
Measured: 12 months after CT1390B infusion
Cmax
the peak of CARgene copy number in peripheral blood
Measured: 28 days after CT1390B infusion
Tmax
time to reach the peak of CARgene copy number in peripheral blood
Measured: 28 days after CT1390B infusion
AUC
area under curve of CARgene copy number in peripheral blood
Measured: 28 days after CT1390B infusion
Tlast
duration of existence of CARgene copy number in peripheral blood
Measured: 28 days after CT1390B infusion

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing CAR-T cells chimeric antigen receptor T cells in people with Relapsed/Refractory Acute Myeloid Leukemia(AML), 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 10 inclusion and 13 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: opening soon, as of the sponsor's last update on 2 Mar 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 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 Ying Wang, Dr (+86-22-23909278, wangying1@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 (AE) after CT1390B infusion (time frame: 12 months after CT1390B infusion). The study lists 3 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 2 Mar 2026.
