About this study

Official title: Phase I/II Study of CD70 Targeted CAR-T Cell Treatment in CD70 Positive Advanced/Metastatic Solid Tumors

In this single-center, single-arm,prospective, open-label, phase 1/2 study, the safety and efficacy of autologous CD70 targeted chimeric antigen receptor modified T (CAR-T) cell therapy will be evaluated in patients with CD70 antigen positive advanced/metastatic solid tumors . In this clinical trial, at least 12 eligible patients in dose escalation period will be enrolled to receive 3 doses of CD70-CAR cell therapy according to the "3+3" principle. In dose expansion period, additional at most 21 eligible patients will be enrolled to receive CD70-CAR-T cell therapy at dose of recommended phase 2 dose(RP2D).

Read the detailed description

Currently, CAR-T cell therapy has already achieved tremendous success in the treatment of hematological malignancies,however, it remains a severe challenge to treat solid tumors due to multiple obstacles,such as absence of tumor specific antigens, complex immunosuppressive tumor microenvironment, and tumor heterogeneity.

CD70 is a member of the tumor factor superfamily and has been found to be highly expressed on the surface of several solid and hematological tumors, correlating with inferior prognosis.Targeting CD70 has emerged as potential novel immunotherapeutic strategy. Investigators have developed CD70-CAR-T cells that could effectively expand and survive,producing strong anti-tumor effects in animal models. Based on the preclinical data, we conduct this clinical trial in order to test the the safety profiles and anti-tumor activities of CD70-CAR-T cells in vivo. In dose escalation period, at least 12 eligible patients will be enrolled and receive 3 doses of CD70-CAR-T cell therapy (1 × 10^6 cells/kg, 3 × 10^6 cells/kg, 1 × 10^7 cells/kg) according to the "3+3" principle. In dose expansion period, additional at most 21 eligible patients will be enrolled to receive CD70-CAR-T cell infusion at dose of RP2D, which is determined by data from dose escalation period, including occurrence of dose limiting toxicities (DLT), pharmacokinetics/pharmacodynamics, efficacy and other parameters, to furtherly evaluate the safety and efficacy profiles of CD70-CAR-T cell therapy.

What is being measured

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

  1. Incidence of treatment related adverse events

    AE is defined as any adverse medical event from the date of randomization to 12 months after CD70-CAR-T cell infusion. Among them, CRS and ICANS were graded according to American Society for Transplantation and Cellular Therapy (ASTCT) criteria. Other AEs were graded according to common terminology criteria for adverse events (CTCAE) v5.0.

    Measured: Up to 12 months since the initiation of CD70-CAR-T cell therapy.

  2. Incidence of dose limiting toxicities (DLTs)

    DLT was defined as CD70-CAR-T cells-related events with onset within first 28 days following infusion: The development of Grade (G) 3 or higher grade CRS lasting > 2 weeks; All G4 non-hematologic toxicities.

    Measured: Up to 28 days since the initiation of CD70-CAR-T cell therapy

  3. Maximum tolerated dose (MTD)

    MTD is defined as the highest dose level of less than or equal to 2 DLT among the 6 subjects finally determined.

    Measured: Up to 28 days since the initiation of CD70-CAR-T cell therapy

Secondary outcomes (7)
  1. Number and copy number of CD70-CAR-T cells

    Number and copy number of CD70-CAR-T cells are evaluated by number in peripheral blood and tumor tissue.

    Measured: Up to 3 years

  2. Objective response rate (ORR)

    Objective response rate includes complete response and partial response defined by investigators according to RECIST 1.1or iRECIST criteria.

    Measured: Up to 3 years

  3. Progression Free Survival (PFS)

    Progression Free Survival is defined as the time from the initiation of CD70-CAR-T cell therapy to documented disease progression or death.

    Measured: Up to 3 years

  4. Time to response (TTR)

    Time to response is defined as the time from the initiation of CD70-CAR-T cell therapy to first assessed CR or PR by investigators according to RECIST 1.1or iRECIST criteria.

    Measured: Up to 3 years

  5. Duration of response (DOR)

    Duration of response is defined as the time from objective response until documented tumor progression among responders.

    Measured: Up to 3 years

  6. Overall Survival (OS)

    Overall Survival is defined as the time from the initiation of CD70-CAR-T cell therapy to documented disease progression or death.

    Measured: Up to 3 years

  7. Pharmacodynamics: Peak level of cytokines in serum

    The cytokines mainly include interleukin-2 (IL-2 ), IL-6, IL-8, IL-10, tumor necrosis factor-α (TNF-α), C reactive protein (CRP), ferritin. Peak was defined as the maximum post-baseline level of the cytokine.

    Measured: Up to 28 days since the initiation of CD70-CAR-T cell therapy

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CD70-targeting CAR-T cells in people with Solid Tumor, Adult, run by Chinese PLA General 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 8 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 17 Jul 2023. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Weidong Han, Ph.D (010-66937231 ext. +86, hanwdrsw@sina.com), 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 (time frame: Up to 12 months since the initiation of CD70-CAR-T cell therapy.). The study lists 3 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 17 Jul 2023.
