About this study
Official title: Phase 3, Two-stage, Randomized Study of ONC-392 Versus Docetaxel in Metastatic Non-Small Cell Lung Cancers That Progressed on PD-1/PD-L1 Inhibitors
The goal of this Phase 3 clinical trial is to study the safety and efficacy of the nextgen anti-CTLA-4 antibody, gotistobart (ONC-392/BNT316), in patients with metastatic non-small cell lung cancer who have disease progressed on anti-PD-1/PD-L1 antibody based therapy. The study will test whether gotistobart, in comparison with chemotherapy agent docetaxel, could prolong the life for NSCLC patients. Patients will be randomized to be treated with either gotistobart or docetaxel, IV infusion, once every 21 days, for up to 17 cycles in approximately one year.
Read the detailed description
This is a seamless 2-stage, randomized, open-label, active-controlled, Phase 3 study. The study population consists of patients with NSCLC who progressed on PD-1/PD-L1 inhibitor. Approximately 630 patients will be enrolled.
Two gotistobart dosing regimens will be tested in Stage I, and one will be selected for Stage II.
Stage I, the dose-confirmation stage, will assess the efficacy and safety of two gotistobart dosing regimens (3 mg/kg Q3W and 6 mg/kg Q3W with 2 loading doses of 10 mg/kg Q3W) in comparison to docetaxel 75 mg/m2 Q3W.
Stage II will assess the safety and efficacy of gotistobart at the selected dosing regimen versus docetaxel on squamous cell NSCLC. Patients will be randomized 1:1 to receive either gotistobart at the selected dosing regimen or docetaxel.

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

| Study group | Role | What they receive |
|---|---|---|
| Arm 1: Gotistobart 6 mg/kg with 2 loading doses of 10 mg/kg, Q3W | Experimental | Gotistobart will be administrated by IV infusion in 60 minutes on day 1 of each cycle. A cycle is 21 days. Receives: Drug: Gotistobart |
| Arm 2: Docetaxel 75 mg/m2, Q3W | Active comparator | Docetaxel will be administrated by IV infusion in 60 minutes on day 1 of each cycle. A cycle is 21 days. Receives: Drug: Docetaxel |
What is being measured
The primary outcome is the main question the study is designed to answer.
Overall Survival (OS)
OS is defined as the time from randomization to the date of death by any cause. Kaplan-Meier estimates of median OS time will be presented by treatment arm with two sided 95% CIs.
Measured: 36 months
Secondary outcomes (3)
Objective response rate (ORR)
Objective response rate (ORR) as assessed by the Investigator per RECIST 1.1
Measured: 36 months
Progression-free survival (PFS)
Progression-free survival (PFS) as assessed by Investigator per RECIST 1.1
Measured: 36 months
Treatment emergent adverse events, treatment related adverse events and immune related adverse events.
Incidence of TEAEs, TRAEs, irAEs will be calculated. The AEs leading to treatment discontinuation will be recorded.
Measured: 36 months

Primary outcome
Overall Survival (OS)
Time frame: 36 months
OS is defined as the time from randomization to the date of death by any cause. Kaplan-Meier estimates of median OS time will be presented by treatment arm with two sided 95% CIs.
3 secondary outcomes
Objective response rate (ORR)
Time frame: 36 months
Progression-free survival (PFS)
Time frame: 36 months
Treatment emergent adverse events, treatment related adverse events and immune related adverse events.
Time frame: 36 months

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Gotistobart and Docetaxel in people with Non Small Cell Lung Cancer, run by OncoC4, Inc. at 152 sites in 12 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 10 inclusion and 9 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: under way, not looking for participants, as of the sponsor's last update on 13 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 152 sites in United States, China, Turkey (Türkiye), Italy, United Kingdom and 7 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
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?
Overall Survival (OS) (time frame: 36 months). 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 NCT05671510, 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 13 Aug 2026; AzTrials last refreshed its copy on 7 Nov 2026.
