Eligibility criteria

Inclusion Criteria: Patients with pathologically (histologically or cytologically) proven diagnosis of HNSCC (larynx, hypopharynx, or oropharynx). Pathologic confirmation may be from either nodal or primary tumour. If a is obtained from nodal disease, a clinically apparent primary tumour on imaging and/or clinical examination must be present.

Diagnostic tonsillectomy or local excision of the primary without removal of nodal disease is permitted.

Diagnostic lymph node excision or limited neck dissections (retrieving ≤ 4 nodes) are permitted HPV positive or negative (by p16 immunohistochemistry). OPC will be classified as p16 at local sites based on greater than 70% strong diffuse nuclear or nuclear and cytoplasmic staining.

For patients with OPC: analysis of p16 status is required For patients with laryngeal/hypopharyngeal cancer: analysis of p16 status is NOT required

Clinical stage T1-2 N1-2 M0 or T3 N0-2 M0 (UICC/AJCC TNM 8th Edition). Staging will be determined based on clinical examination, axial imaging (CT and/or MRI), and whenever available, PET-CT imaging.

The following radiological investigations must be done within 8 weeks of registration:

CT or MRI of the head and neck; PET-CT scan or chest CT scan (PET-CT scan is strongly preferred and highly recommended to be used for eligibility).

Planned definitive RT. Based on clinical and laboratory evaluation and in keeping with local institutional standards, the treating oncologist must declare upfront, that in the absence of the present clinical trial, the patient would be candidate for treatment with concurrent high dose cisplatin every 3 weeks. This would include:

Adequate hematologic function must be documented within 8 weeks prior to registration:

levels of > 8g/dL (the use of transfusion or other intervention to achieve hemoglobin ≥ 8 g/dL is acceptable) count of >100,000 cells/mm3. of > 1500 cells/mm3.

Adequate hepatic function must be documented within 8 weeks prior to registration:

Total \< 2 X institutional . (SGOT)/ALT (SGPT) ≤ 2.5 X institutional upper limit of normal. Albumin ≥ 3.0 g/dL.

Adequate renal function must be documented within 8 weeks prior to registration:

Serum creatinine \< 1.5 mg/dl or (CC) ≥ 50 ml/min determined by 24-hour collection or estimated by Cockcroft-Gault formula

Patients known to be (HIV)+ are permitted.

Patients with >200 and serum HIV viral load of \< 200 copies/mm3 are eligible

HIV+ patients must receive appropriate care and treatment for HIV infection, including antiretroviral medications when clinically indicated, and should be under the care of a physician experienced in HIV management.

HIV testing is not required for eligibility. Must be ≥ 18 years of age.

Must have an (ECOG) performance status of 0-1.

Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to enrollment in the trial to document their willingness to participate.

Patient is able (i.e. sufficiently fluent) and willing to complete the PRO questionnaires in English or Arabic. The baseline assessment must be completed within required timelines, prior to treatment start. Inability (lack of comprehension in English/Arabic, or other equivalent reason such as cognitive issues or lack of competency) to complete the questionnaires will not make the patient ineligible for the study.

Consent to provision of samples of blood and plasma for correlative studies is optional.

The treatment team must be able to commence definitive RT within 6 weeks of randomization.

Women of child bearing potential must use an accepted and effective method of and/or abstain from sexual intercourse while on protocol treatment and for at least 6 months after the last day of RT. Sexually active males must use an accepted and effective method of contraception and/or abstain from sexual intercourse while on protocol treatment and for at least 6 months after the last day of RT.

Women must not be pregnant or breast-feeding (Women in childbearing period will be instructed by treating physician to avoid pregnancy during and 6 months after end of RT). All females of child bearing potential must have a serum or urine pregnancy test to rule out pregnancy within 4 weeks prior to registration. All breastfeeding women should discontinue breastfeeding prior to study registration.

Participants must not be receiving any other standard anti-cancer therapy or experimental agent concurrently with the study drugs.

Prior allergic reaction to cisplatin

Terms in these criteria, in plain language(16)

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.

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.

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).

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.

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.

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.

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.

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.

CD4 count

The number of CD4 cells, a type of white blood cell, in a given amount of blood. It is used to follow how well the immune system is doing in HIV.

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.

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.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

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.

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.

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 Aug 2026 (actual). Primary completion is estimated for Apr 2033, 79 months after the start.

Of 115 non-industry interventional studies with no phase under Squamous Cell Carcinoma of Head and Neck, half reached primary completion within 53 months of starting (the median), counting those still running; a quarter within 34 and three quarters within 90. This study's planned 79 months is above that.

Counting every sponsor, half of 126 studies reached it within 59 months; a quarter within 34 and three quarters within 90.

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.
