Testing Whether Cemiplimab (REGN2810) Plus CDX-1140 Given Prior to Surgery Are Better Than Cemiplimab (REGN2810) Alone in Patients With Stage III-IV Head and Neck Cancer
This phase II trial compares the effectiveness of cemiplimab with CDX-1140 to cemiplimab without CDX-1140 prior to surgery in treating patients with stage III-IV head and neck cancer. Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. CDX-1140 is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Giving cemiplimab with CDX-1140 versus cemiplimab alone before surgery may make the tumor smaller and may reduce the amount of normal tissue that needs to be removed for patients with stage III-IV head and neck cancer.

De-intensified Radiation Therapy With Chemotherapy (Cisplatin) or Immunotherapy (Nivolumab) in Treating Patients With Early-Stage, HPV-Positive, Non-Smoking Associated Oropharyngeal Cancer
This phase II/III trial studies how well a reduced dose of radiation therapy works with nivolumab compared to cisplatin in treating patients with human papillomavirus (HPV)-positive oropharyngeal cancer that is early in its growth and may not have spread to other parts of the body (early-stage), and is not associated with smoking. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial is being done to see if a reduced dose of radiation therapy and nivolumab works as well as standard dose radiation therapy and cisplatin in treating patients with oropharyngeal cancer.

Testing the Addition of the Drug BMX-001, a Radioprotector, or a Placebo to the Usual Chemoradiation Therapy for Patients With Head and Neck Cancer
This phase II trial compares the effectiveness of adding BMX-001 to usual symptom management versus usual symptom management alone for reducing oral mucositis in patients who are receiving chemoradiation for head and neck cancer. Oral mucositis (inflammation and mouth sores) is a common side effect of chemoradiation that can cause pain and difficulty swallowing. Usual management of these side effects typically consists of using mouth rinses and pain medications during treatment and for several weeks after completion of treatment. BMX-001 neutralizes harmful substances in the body, preventing damage to macromolecules such as DNA and minimizes free radical-related toxicity in normal tissues. Adding BMX-001 to usual symptom management may be more effective than usual symptom management alone at reducing oral mucositis in patients receiving chemoradiation for head and neck cancer.

SPECT-CT Guided ELEctive Contralateral Neck Treatment in Lateralized Oropharyngeal Cancer
Oropharyngeal cancer (OPC) is the most common type of head and neck cancer. The current standard treatment for this cancer is radiotherapy (RT) of the tumour and lymph nodes of both sides of the neck, combined with concurrent chemotherapy for advanced stages. Even though a small proportion of patients with this cancer have involvement of the lymph nodes of the neck on the opposite side of the tumour (contralateral involvement) or involvement of the lymph nodes on both sides of the neck (bilateral involvement), bilateral radiotherapy is performed due to the risk of contralateral microscopic involvement, which is invisible on imaging and clinical examination. Bilateral radiotherapy causes more adverse events, leading to a decrease in quality of life. Lymphatic mapping using Single Photon Emission Computed Tomography-Computed Tomography (SPECT-CT) imaging is a technique that visualises the lymphatic drainage of the tumour and thus determines whether radiotherapy should be delivered unilaterally or bilaterally to the lymph nodes. This technique would therefore reduce adverse events and improve quality of life, while maintaining the efficacy of radiotherapy. The goal of the clinical trial SELECT-FR is to investigate if the efficacy of a lymphatic drainage mapping with a SPECT-CT-guided approach is acceptable in terms of two-year Disease Free Survival (DFS) rate in patients with lateralized OPC.

Adaptive De-intensified Radiotherapy Using Circulating Tumor DNA in HPV- Associated Oropharyngeal Cancer
This phase II trial studies how well using circulating tumor deoxyribonucleic acid (DNA) to guide lower dose radiation therapy works in treating patients with human papillomavirus infection (HPV)-associated oropharyngeal cancer. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Recently, a blood test has been developed to detect the human papillomavirus in the blood and determine how many viral particles are present. Researchers want to compare any good and bad effects of using the lower dose radiation therapy with chemotherapy compared to the usual standard of care dose chemotherapy in patients who clear the human papillomavirus particles from their blood.

Cisplatin + Radiotherapy vs Durvalumab + Radiotherapy Followed by Durvalumab vs Durvalumab + Radiotherapy Followed by Tremelimumab + Durvalumab in Intermediate-Risk HPV-Positive Oropharyngeal SCC
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

The Role of Circulating Tumour DNA in Head and Neck Cancer
Cancers of the throat, oropharyngeal squamous cell carcinoma (OPSCC), are highly prevalent across Scotland. Over the past 10 years, both global and Scottish cases of OPSCC have increased, particularly those associated with human papillomavirus (HPV). However there has been little change in techniques for diagnosis and monitoring. Although imaging technologies are improving, results of imaging are often indeterminate and clinicians require additional tools to make informed decisions. With this in mind our research team have established a range of blood- based tests which detect and monitor cancer DNA fragments shed by tumours into the blood stream in OPSCC patients. Our initial studies have shown that such tests, which are minimally invasive compared to surgical biopsy, hold the potential to provide an accurate, "real-time" method to monitor patient response to treatment, identify early relapse and assist in clinical decision making. The investigators aim to expand these results to assist clinical decisions for both virally associated and non-viral associated OPSCC. Following this, the investigators will focus on the poorest prognosis OPSCC group (non-HPV tumours) by applying state-of-the-art DNA detection and sequencing technologies to analyse tumour- derived DNA fragments in the bloodstream, to follow treatment response and to develop new methods for detecting relapse and resistance to treatment in OPSCC. Ultimately, the investigators envisage that the implementation of such genetic assays of tumours and the fragments that they release into the bloodstream will provide a transformative shift in the clinical assessment and quality of life of OPSCC patients in Scotland.

Lattice-Based Radiotherapy and Chemoimmunotherapy for Oropharyngeal Squamous Cell Carcinoma
This single-arm Phase I/II trial evaluates induction chemoimmunotherapy combined with lattice radiotherapy (LRT) in patients with non-low risk oropharyngeal squamous cell carcinoma and primary tumor ≥3 cm or primary tumor and pathologic lymph node ≥3 cm in longest dimension. BOIN12 adaptive dose-finding will guide dose across two anatomical cohorts-primary-tumor only (P) and primary + largest involved node (PN)-with a total target accrual of about 60 evaluable patients. Dose-limiting toxicity is monitored separately in each cohort. If both tolerate the same dose, that unified optimal biological dose (OBD) advances to Phase II; if tolerability differs, the PN-specific OBD expands while the P cohort is analyzed descriptively. After induction, imaging determines response: patients achieving ≥50% volumetric tumor shrinkage receive hypofractionated chemoradiation, whereas those with \<50% shrinkage are treated with conventional fractionation, personalizing definitive therapy according to early safety and efficacy signals.

A Single Arm Phase II Trial in p16-positive Oropharynx Cancer of Selective Dose De-escalation of nodAl VolumEs at Minimal Risk and Primary Site Disease (SAVED)
Patients with human papillomavirus (HPV)-related oropharyngeal cancer generally have very good outcomes. Patients' treatment responses depend more on their individual cancer characteristics and personal risk factors than on the specific type of treatment they receive. However, the different treatments used for this cancer can cause significant side effects. Because outcomes are often favorable regardless of treatment type, reducing treatment-related side effects should be a priority when choosing care. Studies have reported that lowering radiation doses for some patients can reduce side effects while still effectively controlling the cancer. Patients with this type of head and neck cancer typically receive either surgery or radiation as their first treatment. For patients who receive surgery first, radiation to the surgical area and nearby neck lymph nodes is often recommended afterward. In these patients, the study will test whether lowering the radiation dose to low-risk lymph nodes on the side of the neck opposite the tumor can reduce side effects while still effectively controlling the cancer (Method A). For patients who receive radiation as their first treatment, the study will test one or both of two radiation approaches aimed at reducing both short-term and long-term side effects. These approaches include reduced lymph node radiation (Method A, described above) and a tumor dose reduction approach (Method B), which lowers the radiation dose delivered directly to the tumor. Information such as tumor size, the number of cancerous or suspicious lymph nodes, and risk factors like smoking history will be used to determine which patients may be eligible for reduced lymph node radiation (Method A), reduced tumor radiation (Method B), or both. Patients who may qualify for tumor dose reduction (Method B), either alone or combined with Method A, will need an additional blood test called a circulating tumor DNA (ctDNA) test to determine eligibility. The ctDNA test measures small amounts of tumor-related DNA in the blood, which are often elevated at the time of diagnosis. Studies have shown that cancer is more likely to return when ctDNA levels remain positive after treatment. This study will evaluate whether ctDNA levels measured before and during treatment can help identify patients who can safely receive lower radiation doses to the tumor (Method B). Overall, this study aims to safely evaluate two radiation de-escalation approaches in order to lessen short- and long-term side effects while maintaining excellent cancer control.

Three Schedules of CUE-101 Administered Before Surgery or Definitive Chemoradiation Therapy in HLA-A*0201 Positive Patients With Locally Advanced, HPV16-Positive Oropharyngeal Squamous-Cell Carcinoma
This is a phase 2 trial to assess the safety and tolerability of three schedules of CUE-101 administered in the neoadjuvant phase before standard of care (SOC) therapy to treatment naïve, HLA-A\*0201 positive patients with newly diagnosed, locally advanced HPV16+ oropharyngeal squamous-cell carcinoma (OPSCC). This is an exploratory trial of a limited sample size to confirm safety and to assess for pharmacodynamic signals of efficacy in each of three schedules of CUE-101. Safety assessments will be performed at baseline and after CUE-101 administration. To assess for efficacy, peripheral blood and tumor samples will be collected at baseline and after CUE-101 administration. Following CUE-101, patients will proceed with SOC therapy, as prescribed by the treating physician.

Dual-energy CT vs. MRI in the Evaluation of Squamous Cell Carcinomas of the Oral Cavity and Oropharynx
The diagnostic and pre-therapeutic assessment of squamous cell carcinomas requires a neck and chest CT scan and a neck and facial MRI, which is the most effective examination, to establish the TNM stage of the tumor. However, obtaining this complete assessment can delay treatment. Confirmation of the non-inferiority of 40keV dual-energy CT in BOLT compared to MRI would spare the patient an additional MRI examination, speed up the pre-treatment assessment, reduce the loss of opportunity due to delayed treatment, and free up MRI imaging slots, which are still insufficient in the region.

Personalized Elective Neck Irradiation Guided by Sentinel Lymph Node Biopsy in Larynx and Pharynx Cancer. The PRIMO Study.
Rationale \| Elective neck irradiation is performed in head and neck cancer patients treated with definitive (chemo)radiotherapy. The aim is to eradicate nodal metastases that are not detectable by pretreatment imaging techniques. It is conceivable that personalized neck irradiation can be performed guided by the results of sentinel lymph node biopsy. It is expected that elective neck irradiation can be omitted to one or both sides of the neck in 9 out of 10 patients with a clinically negative neck (cN0). For patients with clinically positive ipsilateral nodes (cN1-2b), it is expected that elective irradiation of the contralateral neck can be omitted in 7 out of 10 patients. This will enable better sparing of normal tissues from radiation and result in less permanent long-term radiation side effects with better quality of life. Methods/design \| This is a multicenter randomized controlled trial aiming to compare safety and efficacy of treatment with sentinel lymph node biopsy guided neck irradiation versus standard bilateral elective neck irradiation in 242 patients with cN0-N2b squamous cell carcinoma of the oropharynx, larynx or hypopharynx for whom bilateral elective neck irradiation is indicated. Patients randomized to the experimental-arm will undergo sentinel lymph node biopsy. Based on the histopathologic status of the sentinel lymph nodes, patients will receive no elective neck irradiation (if no nodal metastases found at both sides of the neck), unilateral neck irradiation only (if no nodal metastases found at contralateral side of the neck only) or bilateral neck irradiation (if nodal metastases found at both sides of the neck). Patients randomized to the control arm will not undergo sentinel lymph node biopsy but will receive standard bilateral elective neck irradiation. The primary safety endpoint is the number of patients with recurrence in regional lymph nodes within 2 years after treatment. The primary efficacy endpoint is patient reported xerostomia-related quality of life at 6 months after treatment. Discussion \| If this trial demonstrates that the experimental treatment is non-inferior to the standard treatment in terms of regional recurrence and is superior in terms of xerostomia-related quality of life, this will become the new standard of care.

Comparing an Investigational Scan (F-18 NaF PET/CT) to Standard of Care Imaging (F-18 FDG PET/CT) for Evaluating Vascular Complications in Patients Receiving Radiation Therapy for Head and Neck Cancer
This early phase I trial compares sodium fluoride F-18 (F-18 NaF) positron emission tomography (PET)/computed tomography (CT) to the standard of care imaging scan (and fludeoxyglucose F-18 \[F-18 FDG\] PET/CT) for assessing the effects radiation therapy has on the blood vessels in the neck in patients with head and neck cancers. For people with cancers in the head and neck, doctors often use radiation to target both the tumor and nearby glands. Radiation therapy to this region can affect the blood vessels in the neck that supply blood to the brain. F-18 NaF and F-18 FDG are contrast agents that can be used together with PET/CT imaging to visualize areas inside the body. A PET scan is a procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is taken up. A CT scan is a procedure that uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-dimensional views of tissues and organs. Combining a PET scan with a CT scan can help make the image easier to interpret. PET/CT scans are hybrid scanners that combine both modalities into a single scan during the same examination. Imaging with F-18 NaF PET/CT may be as effective or more effective than the standard F-18 FDG PET/CT for assessing the effects radiation therapy has on blood vessels in the neck in patients with head and neck cancers.

Compartmentalized Postoperative Radiotherapy in Head and Neck Cancer
COMPORT is a multicenter phase II clinical trial evaluating a personalized approach to postoperative radiotherapy in patients with head and neck squamous cell carcinoma (HNSCC). The study investigates whether a risk-adapted, compartmentalized radiotherapy strategy can safely reduce the treatment volume, and thus the side effects, without increasing the risk of tumor recurrence. Eligible patients are those with surgically treated cancers of the oral cavity, oropharynx, larynx, or hypopharynx who have a standard indication for postoperative radiotherapy. The primary outcome is the rate of recurrence in anatomical compartments that would normally be irradiated but are intentionally omitted in this study. COMPORT aims to generate high-level evidence to support a more personalized and less toxic standard of care in postoperative head and neck cancer management.
