A Phase 2 interventional study of Nivolumab Injectable Product and Trans-arterial tirapazamine embolization in Hepatocellular Carcinoma and Gastric Cancer, sponsored by Teclison Ltd.. Recruiting at 3 sites in United States. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-04-16.

This is a multi-center, open-label phase IIA study that investigates the preliminary efficacy of Trans-arterial Tirapazamine Embolization (TATE) treatment of liver cancer followed by a PD-1 checkpoint inhibitor (nivolumab). Patients with two types of cancers will be enrolled, advanced hepatocellular carcinoma (HCC),and metastatic gastric cancer. All enrolled patients need to have liver lesions and have progressed on a prior immune checkpoint inhibitor.
The goal of the study is to investigate whether tumor necrosis induced by Trans-arterial Tirapazamine Embolization (TATE) treatment can boost anti-tumor immunity and enhance the therapeutic efficacy of immune checkpoint inhibitor. Patients with advanced liver cancers (primary HCC or metastatic gastric cancer) who have progressed on a prior immune checkpoint inhibitor will be enrolled in the study. Liver lesions will be treated with up to 4 TATE treatments for optimal debulking, which also serve as a vaccination process toward tumor. Lesion not treated with TATE will be used for monitoring the response toward a PD-1 inhibitor (Nivolumab) for abscopal effect. If a patient subsequently develops an "escape" to the PD-1 inhibitor, patient can have another 2 TATE treatments of the escaped tumor lesion. Dosing of the PD-1 inhibitor is per standard FDA-approved dosing schedule and continues until progressive disease. The efficacy will be assessed by the response rate (RR) using RECIST.

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.
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.
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.
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.
A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.
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.
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.
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.

Started Jul 2017 (actual). Primary completion is estimated for Dec 2026, 113 months after the start.
Of 80 industry-sponsored phase 2 interventional studies under Carcinoma, Hepatocellular, half reached primary completion within 38 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 50. This study's planned 113 months is above that.
Counting every sponsor, half of 428 studies reached it within 43 months; a quarter within 30 and three quarters within 71.
