About this study
Official title: A Phase I Clinical Study to Assess the Safety and Efficacy of CD70-targeted CAR-T in the Treatment of CD70-positive Advanced/Metastatic Solid Tumors
This is a single-center, double-arm, open-label study. this study plans to evaluate the safety and efficacy of CD70-targeting CAR-T cells in the treatment of CD70-positive advanced/metastatic solid tumors, and obtain recommended doses and infusion patterns.
Read the detailed description
The research designs to follow 2 groups：Intravenous infusion group and Intraperitoneal injection group；each group sets up 2 phases,the first phase is dose discovery phase to obtain recommended doses,the second phase is dose expansion phase to verify the safety in the recommended doses. In the discovery phase,each group puts up 4 dose groups, adopting a dose-escalating 3+3 design, and plan to recruit about 12 subjects with CD70-positive advanced/metastatic solid tumors.In the dose expansion phase,each group will choose one or two dose groups to verify the safety and efficacy at this dose,and plan to recruit about 6 subjects in each dose group.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing CD70 CAR-T cells in people with Renal Cell Carcinoma and Ovarian Cancer, run by Chongqing Precision Biotech Co., Ltd 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 17 inclusion and 20 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 8 Nov 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 Fei Li, M.D (13970038386, 691058841@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Adverse events after CD70 CAR-T cells infusion [Safety and Tolerability] (time frame: 28 days). 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?
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 8 Nov 2023.
