What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ATG-101Drug
ATG-101 will be administered intravenously once every 28 days. The dose levels will be determined by the starting dose and the escalation steps taken in the trial. The Dose Expansion Phase will begin at the defined MTD, RP2D, or biologically optimal dose.
| Study group | Role | What they receive |
|---|---|---|
| ATG-101 | Experimental | Dose Escalation Phase:
Will be conducted with an enhanced PDx cohort.
Dose Expansion Phase:
Subjects with advanced or metastatic solid tumors and mature B-NHLs will be enrolled. Receives: Drug: ATG-101 |
What is being measured

AEs/SAEs
Toxicity will be graded according to the NCI CTCAE, Version 5.0.
Measured: One year after last patient first dose
DLT (for Dose Escalation Phase only)
The DLTs will be evaluated during Cycle 1 of treatment. Toxicity will be graded according to the National Cancer Institute-Common Terminology Criteria for Adverse Events. The DLTs for this study may include the following: Cytokine release syndrome, Hematologic toxicity, Non-hematologic toxicity.
Measured: One year after last patient first dose

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ATG-101 in people with Advanced Solid Tumor and Metastatic Solid Tumor, run by Antengene (Hangzhou) Biologics Co., Ltd. at 4 sites 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 6 inclusion and 6 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: stopped early, as of the sponsor's last update on 29 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites 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?
The study was stopped early (reason given: The sponsor has decided to adjust the development strategy of the investigational drug in this study.). Results are not available in the source record.
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?
AEs/SAEs (time frame: One year after last patient first dose). 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 29 Aug 2025.
