About this study

Official title: An Open, Single-arm, Phase 1 Study to Evaluate the Safety/Preliminary Effectiveness and Determine the Maximal Tolerated Dose of B7-H3-targeting CAR-T Cell Therapy in Treating Recurrent Glioblastomas

This is an open-label, single-arm, dose-escalation and multiple-dose study to evaluate the safety, tolerability, and preliminary efficacy of TX103-CAR-T Cell Injection, a B7-H3-targeting chimeric antigen receptor T-cell (CAR-T) therapy, in patients with recurrent glioblastoma. The study also aims to explore the maximum tolerated dose (MTD) and determine the recommended Phase II dose (RP2D) of TX103-CAR-T Cell Injection.

What participants receive

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

  • B7-H3-targeting CAR-T cells/TX103-CAR-T Cell InjectionBiological

    Patients will be treated with anti-B7-H3 autologous CAR-T cells that are delivered into the intracranial tumor resection cavity or ventricular system using an Ommaya device.

Study groups in NCT05241392
Study groupRoleWhat they receive
CAR-T cell therapyExperimentalDose-escalation phase: A "3+3" dose-escalation design is used to determine MTD \& R2PD. Anti-B7-H3 autologous CAR-T cells were given biweekly to patients at the following doses for each cycle, and 4 cycles as one course. Dose1: 3 patients at a dose of 20 million cells for each cycle. Dose 2: 3 patients at a dose of 60 million cells for each cycle. Dose 3: 3 patients at a dose of 150 million cells for each cycle. Dose 4: 3 patients at a dose of 450 million cells for each cycle. Dose 5: 3 patients at a dose of 900 million cells for each cycle. R2PD confirmation phase: Determine the R2PD based on the results from the previous dose-escalation study; Treat another 12 patients with anti-B7-H3 autologous CAR-T cells biweekly at the R2PD to further confirm the safety of R2PD. At each dose phase, if the patients show tolerate and response to the treatment, these patients would receive several courses of treatment at PI's discretion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of Dose Limiting Toxicity (DLT)

    To evaluate the DLT incidence occurred within three months after B7-H3 CAR-T cells infusion

    Measured: three months post CAR-T cells infusion

  2. Safety:Incidence and severity of adverse events

    To evaluate the possible adverse events occurred within three months after B7-H3 CAR-T cell infusion, including the incidence and severity of symptoms such as cytokine release syndrome and neurotoxicity

    Measured: three months post CAR-T cells infusion

Secondary outcomes (5)
  1. Efficacy:Overall survival rate at 12 months

    The proportion of subjects who have survived for more than 12 months since the diagnosis of recurrent glioblastoma

    Measured: 12 months post CAR-T cells infusion

  2. Efficacy:objective remission rate

    The proportion of subjects reaching complete remission / partial remission in optimal remission

    Measured: 1, 2, 3, 4, 5, 6 months post CAR-T cells infusion

  3. pharmacokinetics:Cmax

    observed maximum plasma concentration (Cmax)

    Measured: Samples collected pre-injection, and 1, 2, 3, 5, 7, 9, 11,13 days post the first injection; Samples collected pre-injection, and 2, 7, 13 days post re-injections

  4. pharmacokinetics:Tmax

    time to reach maximum plasma concentration (tmax)

    Measured: Samples collected pre-injection, and 1, 2, 3, 5, 7, 9, 11,13 days post the first injection; Samples collected pre-injection, and 2, 7, 13 days post re-injections

  5. pharmacokinetics:AUC

    area under the plasma concentration-time curve from time zero to 28 days after dosing (AUC(0-28))

    Measured: Sample taken pre-injection, and 1, 2, 3, 5, 7, 9, 11,13 days post the first injection; Sample taken pre-injection, and 2,7,13 days post re-injections

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing B7-H3-targeting CAR-T cells/TX103-CAR-T Cell Injection in people with Glioblastoma, run by Beijing Tiantan Hospital 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 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: under way, not looking for participants, as of the sponsor's last update on 26 Oct 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?

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 Dose Limiting Toxicity (DLT) (time frame: three months post CAR-T cells 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 NCT05241392, which also lists 2 linked publications.

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 26 Oct 2026.
