About this study

Official title: Clinical Study for Evaluating ESO-T01 Injection's Safety and Efficacy in Treating Relapsed/refractory Multiple Myeloma

This is a single center, single arm, open-label, dose-escalation clinical study to observe the safety, tolerability, preliminary efficacy, pharmacokinetics, pharmacodynamics of ESO-T01 injection for treating patients with relapsed/refractory multiple myeloma.

Read the detailed description

ESO-T01 injection is the third-generation self-inactivating lentiviral vector targeting T cells in vivo, which carries a single VHH-directed BCMA-targeted CAR. Before infusion, the patients will be given the prophylaxis of acetaminophen and diphenhydramine. The designed dose-escalation includes four dose groups of dose A, B, C, and D. After infusion, patients will be followed for 2 years.

What is being measured

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

  1. Dose-limiting toxicities (DLTs)

    Dose limiting toxicity will be assessed after injection

    Measured: Dose-limiting toxicities (DLTs) are evaluated between the infusion and 28 days post-infusion.

  2. Cytokine release syndrome (CRS)

    Cytokine release syndrome (CRS) would be graded according to the ASTCT consensus.

    Measured: up to Day 28 post-infusion

  3. immune cell-associated immune effector cell-associated neurotoxicity syndrome (ICANS)

    ICANS would be scored according to Immune Effector Cell-Associated Encephalopathy (ICE), and then graded by the ASTCT consensus.

    Measured: up to Day 28 post-infusion

  4. Treatment-associated adverse effects (AEs)

    All other AEs would be assessed according to the Common Terminology Criteria for Adverse Events (CTCAE, Version 5.0).

    Measured: up to 2 years after treatment of ESO-T01

Secondary outcomes (8)
  1. Overall response rate (ORR)

    Clinical efficacy can be evaluated according to the 2016 International Myeloma Working Group consensus criteria.

    Measured: Day 14, Day 28, Month 2 , Month 3, Month 6, Month 9, Month 12, Month 18, Month24 after the treatment of ESO-T01.

  2. Complete response (CR) rate

    sCR/CR can be evaluated according to the 2016 International Myeloma Working Group consensus criteria.

    Measured: Day 14, Day 28, Month 2 , Month 3, Month 6, Month 9, Month 12, Month 18, Month24 after the treatment of ESO-T01.

  3. Duration of response (DOR)

    DOR is defined as the interval between the first sCR, CR, VGPR, or PR after infusion and the disease progression or death.

    Measured: Through study completion, an average of 2 year

  4. Progression-free survival (PFS)

    PFS is defined as the interval between a subject's receipt of ESO-T01 infusion and the first assessment of disease progression or death.

    Measured: up to 2 years after treatment of ESO-T01.

  5. Overall survival (OS)

    OS is defined as the interval between a subject's receipt of ESO-T01 infusion and death from any cause.

    Measured: up to 2 years after treatment of ESO-T01

  6. Cmax

    CAR-T kinetics would be detected by flow cytometry and droplet digital PCR in peripheral blood and bone marrow at each important time points. Cmax is the peak expansion value of CAR-T cells.

    Measured: Baseline, Day 2, Day 4, Day 6, Day 8, Day 10, Day 12, Day 14, Day 17, Day 21, Day 24, Day 28, Month 2 , Month 3, Month 6, Month 9, Month 12, Month 18, Month24 after the treatment of ESO-T01

  7. Tmax

    CAR-T kinetics would be detected by flow cytometry and droplet digital PCR in peripheral blood and bone marrow at each important time points. Tmax is the time of the occurrence of expansion peak.

    Measured: Baseline, Day 2, Day 4, Day 6, Day 8, Day 10, Day 12, Day 14, Day 17, Day 21, Day 24, Day 28, Month 2 , Month 3, Month 6, Month 9, Month 12, Month 18, Month24 after the treatment of ESO-T01

  8. AUC(0-day 28)

    CAR-T kinetics would be detected by flow cytometry and droplet digital PCR in peripheral blood and bone marrow at each important time points. Cmax is the peak expansion value of CAR-T cells. AUC(0- day28) refers to the area under curve of CAR-T cell expansion between infusion and day 28 post infusion. They all reflect the pharmacokinetics.

    Measured: Baseline, Day 2, Day 4, Day 6, Day 8, Day 10, Day 12, Day 14, Day 17, Day 21, Day 24, Day 28 after the treatment of ESO-T01

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing ESO-T01 in people with Relapsed/ Refractory Multiple Myeloma, run by Chunrui Li 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 14 inclusion and 14 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 11 Feb 2025. 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 Chunrui Li (86-13647233185, cunrui5650@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose-limiting toxicities (DLTs) (time frame: Dose-limiting toxicities (DLTs) are evaluated between the infusion and 28 days post-infusion.). The study lists 4 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 NCT06791681, 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 11 Feb 2025.
