This phase II/III trial studies how well the addition of ivonescimab to standard chemotherapy (gemcitabine and cisplatin) works when compared to usual chemotherapy and immunotherapy (durvalumab or pembrolizumab) in treating patients with biliary tract cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic acid (DNA) and may kill tumor cells. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Immunotherapy with monoclonal antibodies, such as durvalumab and pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Ivonescimab is a bispecific antibody that is directed against both the programmed cell death protein 1 (PD-1) and vascular endothelial growth factor (VEGF) protein. By targeting PD-1, ivonescimab may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. By targeting VEGF, ivonescimab may help stop the formation of blood vessels that bring oxygen and nutrients to tumor. Adding ivonescimab to standard chemotherapy may work better than usual chemotherapy and immunotherapy in lowering the chance of advanced biliary tract cancer growing or spreading.
PRIMARY OBJECTIVE:
I. To compare overall survival (OS) of ivonescimab plus chemotherapy (with gemcitabine and cisplatin) versus standard of care durvalumab or pembrolizumab plus chemotherapy (with gemcitabine and cisplatin) in all randomized patients.
SECONDARY OBJECTIVES:
I. To compare progression free survival (PFS) of ivonescimab plus chemotherapy (with gemcitabine and cisplatin) versus standard of care therapy durvalumab or pembrolizumab plus chemotherapy (with gemcitabine and cisplatin) in all randomized patients.
II. To assess additional measures of clinical activity in all randomized patients including objective response rate (ORR), duration of response, and disease control rate.
III. To assess the safety and tolerability of ivonescimab in combination with gemcitabine and cisplatin.
IV. To assess the pharmacokinetic (PK) profile of ivonescimab in combination with gemcitabine and cisplatin (GemCis).
V. To assess the immunogenicity profile of ivonescimab in combination with GemCis.
CORRELATIVE OBJECTIVE:
I. To perform correlative analyses on tissue and blood biospecimens collected within this trial.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients receive gemcitabine intravenously (IV) over 30-60 minutes and cisplatin IV on days 1 and 8 of each cycle, as well as durvalumab IV over 60 minutes or pembrolizumab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 21 days for 8 cycles in the absence of disease progression or unacceptable toxicity. After cycle 8, patients receive durvalumab IV over 60 minutes or pembrolizumab IV over 30 minutes on day 1 of each cycle with or without gemcitabine IV over 30-60 minutes on days 1 and 8 of each cycle per the investigator's discretion. Cycles repeat every 21 days for up to 2 years from study treatment initiation in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) or magnetic resonance imaging (MRI) and collection of blood and urine samples throughout the study.
ARM B: Patients receive gemcitabine IV over 30-60 minutes and cisplatin IV on days 1 and 8 of each cycle, as well as ivonescimab IV over 60 minutes on day 1 of each cycle. Cycles repeat every 21 days for 8 cycles in the absence of disease progression or unacceptable toxicity. After cycle 8, patients receive ivonescimab IV over 60 minutes on day 1 of each cycle with or without gemcitabine IV over 30-60 minutes on days 1 and 8 of each cycle per the investigator's discretion. Cycles repeat every 21 days for up to 2 years from study treatment initiation in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI and collection of blood and urine samples throughout the study.
After completion of study treatment, patients are followed every 3 months for years 0-2 from randomization and then every 6 months for years 2-3 from randomization.

Inclusion Criteria:
Patient must not have received prior systemic therapy for current metastatic or locally advanced biliary tract cancer
Patient must not be pregnant or breast-feeding due to the potential harm to an unborn fetus and possible risk for adverse events in nursing infants with the treatment regimens being used
Patient must not have prior documented or inflammatory disorders (including inflammatory bowel disease such as colitis or Crohn's disease), systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome (i.e.: granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.). The following are exceptions to this criterion:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.
“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
