About this study
Official title: A Phase 1b/2, Open-Label, Dose Escalation and Expansion Study of ADG116, ADG116 Combined With Toripalimab (Anti-PD-1 Antibody), ADG116 Combined With ADG106 (Anti-CD137 Antibody) in Patients With Advanced/Metastatic Solid Tumors
This is a Phase 1, open-label, dose escalation study in patients with advanced/metastatic solid tumors. Study drug, ADG116, is an anti -CTLA-4 fully human monoclonal antibody that specifically binds to human CTLA-4. ADG106, a fully human ligand-blocking agonistic anti-CD137 IgG4 mAb, is expected to enhance the activity of activated T cells. The enhanced antitumor efficacy results observed from the preclinical studies of ADG116 in combination with ADG106 or anti-PD-1 provided further support to explore such combinations in clinical settings for better patient responses.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ADG116, ADG106 and anti PD1 drug in people with Advanced/Metastatic Solid Tumors, run by Adagene Inc at 4 sites in 2 countries.
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 13 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: finished, as of the sponsor's last update on 8 Jan 2026. 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 Australia, United States. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Number of participants experiencing dose-limiting toxicities escalating dose levels in adults with advanced / metastatic solid tumors (time frame: From first dose of ADG116 (Week 1 Day 1) until 21 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?
On the ClinicalTrials.gov record for NCT04501276, which also lists 3 linked publications.
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 Jan 2026; AzTrials last refreshed its copy on 6 Nov 2026.
