What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]
Measured: 28 Days from first dose of QN-023a
The incidence of subjects with Dose Limiting Toxicities within each dose level cohort
Measured: 28 Days from first dose of QN-023a
Secondary outcomes (3)
Overall Response Rate(ORR)
Measured: Up to approximately 2 years after last dose of QN-023a
Relapse-free survival (RFS) of participants
Measured: Up to approximately 2 years after last dose of QN-023a
Determination of the pharmacokinetics (PK) of QN-023a cells in peripheral blood
The PK of QN-023a in peripheral blood will be reported as the relative percentage of product (QN-023a) DNA versus patient DNA (% chimerism) measured from blood samples at the specified time points
Measured: Up to approximately 2 years after last dose of QN-023a

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing QN-023a, Cyclophosphamid and Fludarabine in people with AML, Adult, 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 7 inclusion and 11 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: stopped early, as of the sponsor's last update on 6 Nov 2024. 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?
The study was stopped early (reason given: It did not reach the expected results of clinical trial). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] (time frame: 28 Days from first dose of QN-023a). 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 6 Nov 2024.
