About this study

Official title: A Clinical Study to Evaluate the Safety and Efficacy of INS19 CAR-T Cells for the Treatment of Relapsed or Refractory Acute B Lymphoblastic Leukemia

This study, a single-center, open, single-dose clinical study, was designed to evaluate the safety, tolerability, and pharmacokinetic profile of INS19 CAR-T cells for the treatment of patients with relapsed or refractory acute B lymphoblastic leukemia

Read the detailed description

The study is planned to enroll 9-12 patients with relapsed or refractory acute B-lymphoblastic leukemia in a modified "3+3" design with two dose groups of 1×10^7 cells and 2×10^7 cells (dose halved for subjects weighing <40 kg). Each dose group is planned to enroll 3-6 subjects to assess safety, and ultimately the SRC will decide whether to continue to add escalating dose groups or to conduct an extension study in a specific dose group based on available safety and efficacy information, with 3-6 subjects to be enrolled in the extension phase.

This study will be divided into a screening period, a cell collection period, a chemotherapy pretreatment period, a return infusion and a follow-up period, and within 28 days of return infusion the investigator will assess whether a DLT (Dose limited toxicity) event has occurred to confirm the safety of this dose group.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing INS19 CAR-T Cells in people with Leukemia, B-cell, run by Beijing Immunochina Medical Science & Technology Co., Ltd..

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 5 inclusion and 27 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: status not confirmed, as of the sponsor's last update on 17 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Xiangyu Zhao, PhD (8610 88326666, Zhao_xy@bjmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Treatment Related adverse events (AEs) (time frame: Up to 28 days after CAR-T 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?

On the ClinicalTrials.gov record for NCT06209671, which also lists 1 linked publication.

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 17 Jan 2024.
