About this study

This study is a single arm, open label, dose exploring clinical trial to evaluate the safety, efficacy, cellular metabolic dynamics, and pharmacodynamics of ct1190b cells in relapsed / refractory B-cell acute lymphoblastic leukemia.

Read the detailed description

The study was divided into dose escalation phase and dose expansion phase. It is planned to enroll 18-36 study participants.

The participants were divided into two treatment groups. Group A was adult participants ≥ 18 years old who received ct1190b treatment. The dose escalation was tentatively determined at three dose levels: dl1:3.0 × 10^8, dl2:4.5 × 10^8, dl3:6.0 × 10^8 car-t cells. , Group B consisted of 12-17-year-old adolescents and children. The dose escalation was tentatively defined as two dose levels. Dl1:3.0 × 10^6 /kg car-t cells, the maximum total number of infused cells was not more than 1.5 × 10^8 car-t cells, dl2:6.0 × 10^6 /kg car-t cells, the maximum total number of infused cells was not more than 3.0 × 10^8 car-t cells. The dose escalation of the two groups followed the "i3+3" design. It was planned to enroll 18-36 study participants. At the dose escalation stage, all patients of different subtypes were mixed into the group. Without distinguishing between groups, the dose escalation of group A was given priority. After obtaining certain data, the dose escalation of group B was performed (fig.it can receive other research data of the same indication of this product). If the starting dose of group A (3.0 × 10^8) meets the dose reduction standard according to the i3+3 principle (the i3+3 decision table indicates "d" or "Du", refer to the incremental decision table of the i3+3 principle for details), the investigator and the funder will jointly discuss and decide whether to enter the decreasing dose of 1.5 × 10^8. If the maximum dose currently set is not confirmed as the possible recommended dose (RD), the investigator and the funder can jointly decide whether to increase it to a higher dose to explore the possible recommended therapeutic dose. During the study, the dose group may be increased or decreased or the dose may be extended according to the safety, effectiveness and cellular metabolic dynamics data of the study participants.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CT1190B cell injectionBiological

    Also called CT1190B

    The active ingredient of the drug in this study is the chimeric antigen receptor targeting cd19/cd20 (car-cd19/cd20 for short) modified allogeneic T cells. In order to reduce the rejection of GVHD and host immune cells, TCR and B2M were knocked out, and the related modifications were also carried out to reduce the host NK cell immune rejection.

  9. The level of CT1190B gene copy number

    Cell metabolic dynamics analysis will be carried out according to different treatment groups. According to the actual blood collection time, individual ct1190b cell copy number time curves (linear and semi logarithmic) were drawn.

According to the actual blood collection time, individual ct1190b cell copy number time curves (linear and semi logarithmic) were drawn. According to the blood collection time, the average and median ct1190b cell copy number time curves (linear and semi logarithmic) were drawn.

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 15 inclusion and 30 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 13 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 Heng Mei, M.D., Ph.D (07596503286, hmei@hust.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The number and severity of dose-limiting toxicity (DLT)events (time frame: Within 28 days after cell infusion). 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 Mar 2026.
