This single-center, open-label, randomized phase II trial evaluates whether CT-guided local ablation of liver and/or lung oligometastases, added to systemic therapy, improves the objective response rate compared with systemic therapy alone in patients with metachronous liver and/or lung oligometastases (no more than 5 lesions, each 3 cm or smaller) from nasopharyngeal carcinoma.
Metachronous metastasis is defined as distant metastasis detected at least 6 months after curative treatment of the primary nasopharyngeal tumor. Eligible participants are randomized 1:1 to local ablation plus systemic therapy or systemic therapy alone.
Ablation is performed under CT guidance by two interventional radiologists; multiple lesions are treated in up to 3 sessions 3-4 weeks apart, and complete ablation is assessed by contrast-enhanced CT or PET/CT 3-4 weeks after ablation.
Systemic therapy in both arms consists of gemcitabine 1000 mg/m2 on days 1 and 8 plus cisplatin 80 mg/m2 on day 1 with a PD-1 inhibitor on day 1 every 3 weeks for 6 cycles, followed by PD-1 inhibitor maintenance every 3 weeks for up to 2 years. Tumor response is assessed per RECIST 1.1 every 8 weeks. Adverse events are graded per NCI CTCAE v5.0.
The sample size of 138 (69 per arm) provides 80% power at a two-sided alpha of 0.05 to detect an improvement in objective response rate from 70% to 90%, allowing for 10% dropout.

Exclusion Criteria:
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.
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 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 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 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.
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).
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.
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.
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.
PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.
PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
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.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
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.

Start is estimated for Oct 2026; primary completion for Aug 2028, 22 months later.
Of 128 non-industry phase 2 interventional studies under Nasopharyngeal Carcinoma, half reached primary completion within 49 months of starting (the median), counting those still running; a quarter within 31 and three quarters within 74. This study's planned 22 months is below that.
Counting every sponsor, half of 143 studies reached it within 43 months; a quarter within 28 and three quarters within 65.
