Interim Analysis
Participants are eligible for this study who were treated for advanced biliary tract cancer (BTC) but the treatment either did not make the cancer better or is no longer working. The treatment for patients whose advanced BTC either did not make the cancer better or is no longer working is a combination of chemotherapy drugs called FOLFOX which consists of fluorouracil and oxaliplatin. Studies have shown that other treatments may work better to treat advanced BTC. In this study, investigators want to see if treating patients with the drug combination of trifluridine/tipiracil (FTD/TPI) and another drug called oxaliplatin works better than FOLFOX for advanced BTC as second-line therapy. FTD/TPI are pills that are taken by mouth, whereas oxaliplatin is given intravenously (by IV).
BTCs are difficult to treat. It is estimated that in the United States (US) approximately 15,000-20,000 people will be diagnosed with a BTC per year. In 2024, liver and intrahepatic bile duct cancers were the 5th leading cause of death from cancer among men and 7th among women in the US (1). Most people with BTCs have cancer that has spread or cannot be removed with surgery, so systemic treatments are the only option. However, the median survival after being diagnosed with an advanced BTC is still only 4.5 months, so it is important that we find better treatment options (2).
This study is evaluating the combination of a medicine called trifluridine/tipiracil (FTD/TPI) and a medicine called oxaliplatin in treating advanced BTCs. While FTD/TPI has been used to treat other types of cancer, it is not yet approved to treat BTCs, so it is experimental. On the other hand, oxaliplatin is a medicine that has been previously used to treat BTCs.

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.
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.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
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.
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 standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
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.

Participants will complete 14-day treatment cycles of FTD/TPI plus oxaliplatin, continuing until disease progression, intolerable toxicities, or participant withdrawal from the trial.
Drug: Trifluridine/tipiracil · Drug: Oxaliplatin
FTD/TPI will be taken by mouth on Days 1-5 of the 14-day treatment cycle. The starting does is 25mg/m2 twice per day.
Also known as: FTD/TPI
Oxaliplatin is given on Day 1 of each 14-day cycle. It is given intravenously (by IV) over 2 hours.
Disease control rate (DCR) by RECIST v1.1
DCR is the percentage of participants whose cancer did not get worse after treatment (i.e. the percentage of participants who had CR, PR, or SD, as defined below), and this will be measured by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria. Per RECIST v1.1, Complete Response (CR) is defined as disappearance of all target lesions. Partial Response (PR) is defined as a 30% decrease in the sum of diameters of target lesions. Progressive Disease (PD) is defined as a 20% increase in the sum of diameters of target lesions with an absolute increase of at least 5 millimeters (mm) or the appearance of one or more new lesions. Stable Disease (SD) is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.
