Study summary

This research study is studying a combination of drugs as a possible treatment for Hepatocellular Carcinoma or Biliary Tract Cancer.

The interventions involved in this study are:

  • Durvalumab
  • Tremelimumab
  • Radiation Therapy
Read the detailed description

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of investigational drugs to learn whether the drugs work in treating a specific disease. "Investigational" means that the drugs are being studied.

The FDA (the U.S. Food and Drug Administration) has not approved durvalumab for this specific disease but it has been approved for other uses.

The FDA has not approved tremelimumab as a treatment for any disease.

Both durvalumab and tremelimumab are antibodies (proteins that work with the immune system) that target proteins produced by the cancer cells. These cancerous proteins suppress the immune system which allows the cancer cells to grow. The study drugs may target these cancerous proteins and stop the cancer cells from suppressing the immune system.

The investigators hope that the combination of these study drugs with radiation therapy will help stop the cancer cells from growing and spreading.

Terms in these criteria, in plain language(32)

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.

Histologically or cytologically confirmed

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.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

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.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

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.

Hepatitis B tests

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 tests

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.

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.

Hemoglobin (Hb)

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).

Absolute neutrophil count (ANC)

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.

Platelets

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.

Bilirubin

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.

ULN (upper limit of normal)

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.

ALT and AST (liver enzymes)

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.

INR, PT and aPTT (clotting tests)

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.

Creatinine clearance (CrCl)

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.

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.

Reproductive potential

Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.

Criteria about it usually ask for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

PD-1, PD-L1 and checkpoint inhibitors

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.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

QT and QTc

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.

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.

Cancer (malignancy)

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.

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.

Corticosteroids (steroids)

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.

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.

HIV

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.

Contraception

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.

CTCAE grade

The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.

1
Mild.
2
Moderate.
3
Severe.
4
Life-threatening.
5
Death due to the event.

“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.

Brain metastases

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.

What researchers measure

Primary outcomes

  1. Best Overall Response rate

    The number of participants that achieve either a complete response or partial response. Response rate (ORR) is assessed using irRECIST (Immune-related Response Evaluation Criteria In Solid Tumors). Response is evaluated with the use of computed tomography (CT) and magnetic resonance imaging (MRI) scans. Participants are evaluated for response for the duration of treatment.Treatment continues until disease progression, treatment is considered a safety risk, physicians decision, withdrawal from the study, or until the participant is lost to follow up. The best overall response recorded for each participant is reported. * Complete Response: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 mm (the sum may not be "0" if there are target nodes) * Partial Response: At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters

    Time frame: Start of cycle 3, start of cycle 5, and then the start of every subsequent cycle for the remainder of treatment. One cycle is 4 weeks. (approximately 3 years)

Secondary outcomes

  1. Number of Participants With Treatment Related Adverse Events

    The number of participants that experience treatment related adverse events as assessed using Common Terminology Criteria for Adverse Events (CTCAE 4). Participants are evaluated for adverse events for the duration of treatment.Treatment continues until disease progression, treatment is considered a safety risk, physicians decision, withdrawal from the study, or until the participant is lost to follow up.

    Time frame: From the start of treatment until 30 days after the last dose of study drug is received (approximately 5 years)

  2. Overall Survival

    The median overall duration of survival as measured from the start of treatment until the time of death due to any cause or until the participant is lost to follow-up.

    Time frame: From the start of treatment until the time of death or loss to follow-up (approximately 7 years)

  3. Disease Control Rate

    The number of participants that achieve a complete response (CR), partial response (PR), or stable disease (SD) as their best overall response as evaluated using irRECIST (Immune-related Response Evaluation Criteria In Solid Tumors). Participants are evaluated for response for the duration of treatment. Treatment continues until disease progression, treatment is considered a safety risk, physicians decision, withdrawal from the study, or until the participant is lost to follow up. * CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 mm (the sum may not be "0" if there are target nodes) * PR: At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters * SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum of diameters while on study

    Time frame: Screening, start of cycle 3, start of cycle 5, and then the start of every subsequent 4-week cycle for the remainder of treatment (approximately 3 years)

  4. Progression Free Survival

    The median amount of time from the start of treatment until the the first documentation of radiographic disease progression (per irRECIST) or death due to any cause, whichever occurs first. Participants who are alive with no documented disease progression by the data cutoff date for progression free survival analysis will be censored at the date of their last evaluable disease assessment. • Prior Progressive Disease: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: The appearance of one or more new lesions may be considered progression.)

    Time frame: From the start of treatment until the time of death or loss to follow-up, whichever occurs first (approximately 7 years)

  5. Duration of Response

    The median duration of time from first documentation of objective response to the first documented disease progression (per irRECIST). For participants who are alive and no documented progressive disease at the time of data cutoff for analysis, duration of response will be censored at the last evaluable disease assessment date.

    Time frame: From first documentation of response to treatment until the time of disease progression (approximately 2 years)

  6. Time to Disease Progression

    The median duration of time from the start of treatment to the first documentation of radiographic disease progression (perirRECIST). Participants with no documented progressive disease by the data cutoff date for time to progression analysis will be censored at the date of their last evaluable disease assessment.

    Time frame: From the start of treatment until the time of disease progression (approximately 7 years)

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.
