Study population

The study population will be made up of patients with histologically or radiologically confirmed advanced or uHCC not amenable to surgery and/or locoregional therapies, and without previous systemic therapy for HCC who are starting treatment with STRIDE as per routine clinical practice and independently of participation in this study. The study aims to enroll approximately 200 patients.

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.

Terms in these criteria, in plain language(8)

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.

Informed consent

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.

Child-Pugh class

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.

ECOG performance status

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.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

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.

Line of therapy

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.

Autoimmune disease

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.

Immunosuppression

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.

Hypersensitivity

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.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Groups and cohorts

  • aHCC/uHCC

    patients with advanced or unresectable HCC (uHCC) treated with STRIDE in Italy according to routine clinical practice.

    Drug: STRIDE

Interventions

  • DrugSTRIDE

    Tremelimumab 300 mg as a single dose administered in combination with durvalumab 1500 mg at Cycle 1/Day 1, followed by durvalumab monotherapy every 4 weeks.

This study also gives Durvalumab, Tremelimumab. No intervention listed here names it: that was found by reading the record.

What researchers measure

Primary outcomes

  1. Time To Decompensation (TTDec)

    time from index date (start of new treatment) to the first occurrence of events such as ascites of any grade according to the European Association for the Study of the Liver (EASL) classification, hepatic encephalopathy of any grade according to West Haven classification, variceal hemorrhage, or jaundice (total bilirubin \>3 mg/dL). In Child-Pugh (CP)-A participants with a score of 6 at index date, TTDec is defined as the time from index date to any worsening in ascites, hepatic encephalopathy, variceal hemorrhage, or jaundice (defined as an increase in total bilirubin to greater than 3 mg/dL or a worsening of more than 1.0 mg/dL from index date). At the time of decompensation (± 30 days) a CT scan should be performed to exclude worsening of liver function due to tumor progression.

    Time frame: From index date to first hepatic decompensation/study completion, up to 30 months

Secondary outcomes

  1. Time To Worsening (TTWors)

    Time To Worsening (TTWors) based on the EORTC QLQ-C30 and QLQ-HCC18 PROs within the first 18 months of treatment. TTWors is the time from first treatment to first clinically meaningful deterioration confirmed at a subsequent visit/assessment or death from any cause. A clinically meaningful change (deterioration or improvement) is defined as an absolute change ≥ 10 points in total score from index date.

    Time frame: Baseline and every 8 weeks during treatment, up to 30 months

  2. Overall Survival (OS)

    time from first treatment to death

    Time frame: From index date through study completion, up to 30 months

  3. Progression free survival (PFS)

    time from first treatment to radiologic evidence of tumor progression or death based on investigator assessment (RECIST v1.1).

    Time frame: From index date until tumor progression, assessed until study completion, up to 30 months

  4. Overall response rate (ORR)

    proportion of participants with a complete response (CR) or partial response (PR) per RECIST v1.1.

    Time frame: From index date until objective tumor progression, assessed until study completion, up to 30 months

  5. Disease Control Rate (DCR)

    proportion of participants with a CR, PR, or stable disease (SD) per RECIST v1.1. (stable disease needs to be maintained for a minimum of 8 weeks to be included in the DCR).

    Time frame: From index date until objective tumor progression or date of death, assessed until study completion, up to 30 months

  6. Downstaging

    Proportion of participants who undergo liver transplant following downstaging with the STRIDE regimen

    Time frame: From index date until study completion, up to 30 months

  7. safety

    Adverse events: severity, seriousness, causality, action taken with durvalumab, and outcome.

    Time frame: From index date until study completion, up to 33 months

Other outcomes

  1. TTDec subgroups

    defined for the primary outcome within the first 18 months of treatment by: • Baseline ALBI grade (1 vs 2 or 3) • Cirrhosis at baseline (yes vs no) • Signs of portal hypertension at baseline, i.e., splenomegaly and thrombocytopenia and presence of collateral circulation, or porto-systemic shunts (yes vs no)

    Time frame: From index date to first hepatic decompensation/study completion, up to 30 months

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2026 (actual). Primary completion is estimated for Oct 2028, 30 months after the start.

Of 49 industry-sponsored observational studies under Carcinoma, Hepatocellular, half reached primary completion within 41 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 58. This study's planned 30 months is below that.

Counting every sponsor, half of 352 studies reached it within 51 months; a quarter within 32 and three quarters within 108.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
