Study summary

Sometimes, cancer patients receive an initial treatment, followed by additional treatment to lower the chance of cancer coming back. The standard or usual treatment for this type of disease is initially having radiation therapy at the same time as chemotherapy (with a drug called cisplatin), with no additional therapy afterwards

Read the detailed description

This study is looking at whether a type of drug called durvalumab can be used with radiation during the initial treatment, (instead of cisplatin) and also afterwards as additional therapy. Durvalumab is an immunotherapy drug . It has been tested in many different types of cancers. Durvalumab works by allowing the immune system to detect the cancer and reactivate the immune response. This may help to slow down the growth of cancer or may cause cancer cells to die. Durvalumab has been shown to shrink tumours in animals. It has been studied in more than 5000 people, approved for use in other cancers and seems promising.

This clinical trial will also test another type of immunotherapy drug called tremelimumab, which would also be given as additional treatment. Tremelimumab works in a different way to durvalumab to enhance the immune system reaction against cancer cells and may improve the effect of durvalumab. Tremelimumab may also help slow the growth of the cancer cells or may cause cancer cells to die. It has been shown to shrink tumours in animals. Tremelimumab has been studied in over 1200 people, approved for use in other cancers and seems promising.

As of February 2019, tremelimumab will no longer be tested with new participants joining the study.

Terms in these criteria, in plain language(24)

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.

Childbearing potential

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.

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.

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.

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).

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.

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.

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.

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

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.

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.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

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.

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.

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.

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.

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.

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.

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.

What researchers measure

Primary outcomes

  1. 3 year event-free survival

    Event-free survival (EFS), is defined as the time from randomization to the time when a failure event is observed. Failure is define by Local-regional progression or recurrence, Distant metastasis, Non-protocol RT, chemotherapy, Surgery or death.

    Time frame: 3 years

Secondary outcomes

  1. Functional Assessment of Cancer Therapy-Head and Neck Version (FACT-HN) score.

    The FACT-H\&N is a multidimensional, self-report QoL instrument specifically designed for use with head and neck cancer patients (1-3). It consists of 27 core items which assess patient function in four domains: Physical, Social/Family, Emotional, and Functional well-being, which is further supplemented by 12 site specific items to assess for head and neck related symptoms. Each item is rated on a 0 to 4 Likert type scale, and then combined to produce subscale scores for each domain, as well as an global QoL score. Higher scores represent better QoL.

    Time frame: 6 years

  2. Local regional failure

    Locoregional control defined as time from randomization to the time of first documented local (primary site) or regional (lymph node) recurrence

    Time frame: 6 years

  3. Distant metastasis-free survival

    Distant metastasis-free survival defined as time from randomization to the time of first documented distant metastasis or death from any cause

    Time frame: 6 years

  4. Overall survival

    Overall Survival defined as time from randomization to the time of death from any cause

    Time frame: 6 years

  5. Cost-effectiveness of immunotherapy-based treatment arm vs standard of RT and cisplatin in patients with intermediate risk LA-OSC using the EQ-5D-5L

    Time frame: 6 years

  6. Number and severity of adverse events

    Time frame: 6 years

  7. Cost-utility will be used to abstract indirect costs at the end of RT and at 6 and 12 months post RT

    Time frame: 6 & 12 months

  8. Lost productivity questionnaire will be used to abstract indirect costs at the end of RT and at 6 and 12 months post RT

    Time frame: 6 & 12 months

  9. Incidence of second cancer

    Time frame: 6 years

  10. PRO-CTCAE baseline, last week of treatment, 3 months, 6 months and 12, 24 and 36 months from the end of RT

    Time frame: 3, 6, 12, 24 and 36 months

  11. Dysphagia: PSS-HN swallowing subscale at 36 months from the end of RT

    Time frame: 36 months

  12. Dysphagia: using MDADI Global at 36 months from the end of RT

    Time frame: 36 months

  13. Number and severity of radiation-related late toxicity at 3 months, 6 months and 1 year from the end of RT

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.
