About this study

Official title: A Study to Evaluate the Safety, Tolerability, Preliminary Efficacy, Pharmacodynamics and Immunogenicity of Universal CNK-UT Cells in Patients With Advanced Solid Tumors.

This is a single arm, open-label, multi-center, phase I study to evaluate the safety, tolerability, preliminary efficacy, pharmacodynamics and immunogenicity of universal chimeric natural killer receptor modified T-cells (CNK-UT) targeting NKG2D-Ligands and NCR2-Ligands with or without lymphodepletion in advanced solid tumors.

Read the detailed description

This is a single arm, open-label, multi-center, phase I, dose escalation/indications expansion study to assess the safety and tolerability of CNK-UT cells therapy, and to obtain the preliminary efficacy, pharmacodynamics and immunogenicity result in participants who have been diagnosed with advanced solid tumors and failed to standard systemic treatment.

What participants receive

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

  • Universal Chimeric Natural Killer Receptor Modified T-cells (CNK-UT)Biological

    1. Dose Escalation: After enrollment, participants will recieve preconditioning by lymphodepletion or not, and then will be treated with CNK-UT cells with a "3 +3" design to determine the maximum tolerated dose. 3 dose level of CNK-UK cells will be tested: 4.6E6/kg，1.5E7/kg，4.6E7/kg. The participants will first receive a single ascending dose(SAD) mode of administration. During the DLT observation period (21 days), if the participants do not experience DLT, they will receive a multiple ascending dose(MAD) mode of administration.
    2. Indications Expansion: It will be carried out after all participants have completed the DLT observation in the Dose Escalation phase. The target population, dosage and frequency of drug administration in the indication expansion stage can be adjusted and determined according to the previous research results.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Universal Chimeric Natural Killer Receptor Modified T-cells (CNK-UT) in people with Advanced Solid Tumors, run by Zhejiang University 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 11 inclusion and 25 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 4 Aug 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 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 Yang Gao (+86 0571 87235147, gaoyang954@zju.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 1 year). 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 NCT05976906.

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 4 Aug 2023.
