About this study
Official title: A Randomised, Phase II Trial to Evaluate the Efficacy of Ivonescimab, a PD 1/VEGF Bispecific Antibody, Versus FOLFOX as Second Line Therapy for Locally Advanced/Metastatic Biliary Cancers
The object of this trial is to test whether ivonescimab is superior to standard chemotherapy (FOLFOX regimen) for the treatment of patients with advanced biliary tract cancer after failure of a first line of chemotherapy. It is only open to patients who participated in the SAFIR-ABC10 trial (NCT05615818) but did not receive experimental treatment.
Eligible patients will be randomised (2:1) to receive either ivonescimab or FOLFOX. Treatment will be continued until disease progression, or a maximum of 34 cycles of ivonescimab (experimental arm), whichever occurs first.
Read the detailed description
This is a Phase 2, multicentre, randomised, two-arm, open-label trial to evaluate whether ivonescimab is superior to standard second-line chemotherapy in the treatment of patients with advanced biliary tract cancer.
The trial will be open to patients who participated in the screening phase of the SAFIR-ABC10 protocol (NCT05615818) and who experienced disease progression on or following the first-line standard of care (CISGEM regimen).
A total of 72 patients will be enrolled and randomly assigned (2:1) to receive treatment with either:
- Experimental arm: Ivonescimab 20 mg/kg by intravenous infusion (IV) once every 3 weeks (Q3W).
- Control arm: Standard second-line chemotherapy - FOLFOX regimen Response to treatment will be assessed according to RECIST v1.1 by radiographic exams performed every 42 (±7) days. Patients will continue treatment until disease progression or for a maximum of 34 cycles of ivonescimab (experimental arm), whichever occurs first.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
IvonescimabDrug
20 mg/kg IV infusion every 3 weeks
FOLFOX regimenDrug
oxaliplatin 85 mg/m² IV, leucovorin 200 mg/m² IV (or folinic acid 400 mg/m²), and fluorouracil (5-FU) 400 mg/m² IV bolus; followed by 5 FU 2400 mg/m² as a 46 hour continuous IV infusion, every 2 weeks
| Study group | Role | What they receive |
|---|---|---|
| Experimental | Experimental | Experimental treatment under study Receives: Drug: Ivonescimab |
| Control | Active comparator | Standard of care second-line treatment for advanced biliary tract cancer Receives: Drug: FOLFOX regimen |
What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-free survival (PFS)
The progression-free survival is the length of time during and after the treatment of a disease that a patient lives with the disease but it does not get worse.
Measured: From randomisation to disease progression or death, up to 4 years
Secondary outcomes (4)
Overall Survival (OS)
The overall survival is the length of time from randomization that patients enrolled in the study are still alive.
Measured: From randomisation to death, up to 4 years
Objective response rate
The proportion of patients achieving complete response (CR) or partial response (PR) (according to RECIST v1.1). Objective response rate will be presented as the best response achieved compared to the disease assessment performed at randomisation.
Measured: From randomisation, up to 4 years
Disease control rate
The proportion of randomised patients achieving CR, PR, stable disease (SD) as assessed by the investigator according to RECIST v1.1
Measured: From randomisation, up to 4 years
Duration of response
The time from first documented response (compared to baseline measurement taken at randomisation) until the date of disease progression, as assessed by the investigator according to RECIST v1.1, or death from any cause whichever occurs first.
Measured: From response to disease progression or death, up to 5 years

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Contact Daniel Couch (+33 (0)1 80 50 12 96, d-couch@unicancer.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-free survival (PFS) (time frame: From randomisation to disease progression or death, up to 4 years). 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 28 Aug 2026.
