Increased pyruvate-to-lactate conversion is a hallmark of HCC metabolism. In parallel, activation of pro-inflammatory immune cells triggers a metabolic switch towards anaerobic glycolysis. Hyperpolarized carbon-13 (13C) pyruvate MRI is a state-of-the-art non-invasive imaging method that offers real-time insights into tissue metabolism. Recent studies have demonstrated its promising potential in predicting responses to radiotherapy and immunotherapy in solid tumors, given the significance of pyruvate as a downstream metabolite in glycolysis. However, its application in assessing treatment response in hepatocellular carcinoma (HCC) patients remains unclear. The establishment of quantitative imaging biomarkers for predicting responses to radio-immunotherapy is an unmet need in the management of HCC patients.
While radiotherapy (RT) effectively controls localized tumors through the induction of unrepairable DNA double-stranded breaks (DSBs) and cell death, its therapeutic efficacy on distal, non-irradiated tumor cells is limited, with out-of-field recurrence being a common pattern of failure in HCC patients treated with high-dose irradiation. Atezolizumab (anti-programmed death-ligand 1; anti-PD-L1) in conjunction with bevacizumab (anti-vascular endothelial growth factor; anti-VEGF) has recently emerged as the standard first-line systemic treatment for unresectable hepatocellular carcinoma (HCC). Despite an objective response rate (ORR) of only 27%, the majority of patients succumb to HCC progression and liver failure. Our preclinical study (Hsieh et al., Science Immunology 2022) uncovered that RT, when combined with PD-L1/PD-1 blockade, induces immunogenic cell death and tumor antigen cross-presentation in antigen-presenting cells, enhancing systemic antitumor T cell responses in murine tumor models. Recent retrospective cohorts suggest that RT targeting all hepatic tumors combined with PD-L1/programmed death-1 (PD-1) blockade is associated with an improved ORR and median progression-free survival (PFS) in patients with unresectable HCC, demonstrating a favorable safety profile. The synergistic antitumor effects of this combination therapy with RT, atezolizumab, and bevacizumab have led to its increasing adoption in routine clinical practice.
This phase II non-randomized trial aims to prospectively investigate the predictive value of hyperpolarized 13C-MRI, along with comprehensive metabolomics and radiomics analyses, for immune response assessment including tumor control outcomes and toxicity in patients with HCC undergoing radiotherapy, atezolizumab, and bevacizumab.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Participants must have diagnosis of HCC that is deemed unsuitable for surgical resection or transplant and will undergo radiotherapy, atezolizumab, and bevacizumab. Participants may have multiple lesions with a total maximal tumor dimension of \< 20 cm, and no one lesion > 15 cm. Diagnosis should be confirmed by at least 1 criteria listed below:
Adequate bone marrow, liver, and renal function within 4 weeks before study registration
Exclusion Criteria:
Severe, active co-morbidity, defined as follows:
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.
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.
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.
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.
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.
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.
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 that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
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.
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 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.
