What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares a newer, precise radiation method called stereotactic body radiotherapy (SBRT) with standard radiation therapy for people with advanced head and neck cancer who cannot have curative treatment. About 196 adults will be randomly assigned to one of the two radiation approaches. The main goal is to see if SBRT helps people live longer and better controls the cancer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Histologically confirmed mucosal squamous cell carcinoma (SCC) of the head and neck arising from at least one of the following sites: oro/hypopharynx, oral cavity, supraglottic larynx, maxillary sinus, nasal cavity, or unknown primary * Stages TX or T0-T4/N0-N3 * Must be considered unfit for curative intent RT as determined by the treating oncologist(s) * Geriatric 8 score \<14 * Patient must be ≥18 years of age * Staging CT or MRI of the head and neck within 8 weeks prior to randomization * Chest CT or x-ray. PET CT is permitted if CT is of diagnostic quality. * Eastern Cooperative Oncology Group (ECOG) Performance Status 0-3 * Participants of childbearing potential must have agreed to use a highly effective contraceptive method during protocol therapy. * Patients with a prior malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational treatment are eligible for this trial. Exclusion Criteria: * Patients with nasopharyngeal carcinoma. * Prior systemic therapy (including immunotherapy). * Prior radiotherapy to the head and neck excluding superficial radiotherapy for head and neck skin cancer that does not overlap with current protocol treatment. * Prior head and neck cancer excluding skin cancer. * Patients with tumour locations/at risk of SBRT toxicity, including glottic/subglottic larynx, T4 hypopharynx, post-cricoid, cervical esophagus, circumferential pharyngeal involvement, extension/proximity to brain/optic structures, any single tumour mass \>8 cm (in one dimension). * \> 2 nodal levels (Level 1a/b not counted); retropharyngeal lymph nodes (where the closest edge is \< 2cm from the closest edge of CTV (primary or nodal) will not be considered as a different level). Note: a single lymph node mass that spans 2 levels will be considered as 1 level. * Gross tumour poorly visualized on CT/MRI. * Definitive radiological or clinically evident distant metastases. * Scleroderma/CREST syndrome.
