What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence, severity, and category of treatment-emergent adverse events (TEAEs)
An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.
Measured: Through study completion, an average of 2 years afterCD19/CD20 Dual-Target in vivo CAR-T Lentiviral infusion (Day 1)
Objective response rate (ORR) and complete response (CR) rate (or the proportion of subjects achieving very good partial response [VGPR] or better) assessed per protocol-specified efficacy evaluation criteria stratified by disease type
Objective Response Rate (ORR) is defined as the proportion of subjects who achieve CR or PR after treatment via CD19/CD20 Dual-Target in vivo CAR-T Lentiviral cell infusion
Measured: Through study completion, an average 2 years after CD19/CD20 Dual-Target in vivo CAR-T Lentiviral infusion (Day 1)
Secondary outcomes (7)
Further evaluation of efficacy endpoints stratified by disease subtype: Time to Response (TTR)
Time to Response (TTR) is defined as the time from the date of first infusion of CD19/CD20 Dual-Target in vivo CAR-T Lentiviral to the date of the first response evaluation of the subject who has met all criteria for CR or PR
Measured: Through study completion, an average 2 years after CD19/CD20 Dual-Target in vivo CAR-T Lentiviral infusion (Day 1)
Further evaluation of efficacy endpoints stratified by disease subtype: Duration of Response (DOR)
Duration of Remission (DOR) is defined as the time from the first documentation of remission (CR or PR) to the first documented relapse evidence of the responders
Measured: Through study completion, an average 2 years after CD19/CD20 Dual-Target in vivo CAR-T Lentiviral infusion (Day 1)
Further evaluation of efficacy endpoints stratified by disease subtype: Progression Free Survival (PFS)
Progression Free Survival (PFS) is defined as the time from the date of first infusion of the CD19/CD20 Dual-Target in vivo CAR-T Lentiviral to the first documented disease progression or death, whichever occurs first.
Measured: Through study completion, an average 2 years after CD19/CD20 Dual-Target in vivo CAR-T Lentiviral infusion (Day 1)
Further evaluation of efficacy endpoints stratified by disease subtype: Overall Survival (OS)
Overall Survival (OS) is defined as the time from the date of first infusion of CD19/CD20 Dual-Target in vivo CAR-T Lentiviral to death of the subject
Measured: Through study completion, an average 2 years after CD19/CD20 Dual-Target in vivo CAR-T Lentiviral infusion (Day 1)

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing CD19/CD20 Dual-Target in vivo CAR-T Lentiviral in people with Relapsed/Refractory B-cell Malignancies, run by The First Affiliated Hospital with Nanjing Medical University 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 12 inclusion and 6 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 13 Aug 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 Lei Fan (13813976136, fanlei3014@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence, severity, and category of treatment-emergent adverse events (TEAEs) (time frame: Through study completion, an average of 2 years afterCD19/CD20 Dual-Target in vivo CAR-T Lentiviral infusion (Day 1)). 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 13 Aug 2026.
