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 Chemotherapy or Chemo-Immunotherapy to the Usual Surgery for Advanced Head and Neck Cancer

This phase II trial tests the addition of chemotherapy, with carboplatin and paclitaxel, or chemo-immunotherapy, with carboplatin, paclitaxel and cemiplimab to standard salvage surgery followed by post operative radiation therapy and cisplatin for high risk patients, for the treatment of patients with PD-L1 positive head and neck squamous cell carcinoma that has come back and spread to nearby tissue or lymph nodes after a period of improvement (locally recurrent) or is persistent. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. 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. Salvage surgery is surgery that takes place to remove tumor tissue after a failure of other treatment. High risk patients also receive radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Adding chemotherapy or chemo-immunotherapy to standard salvage surgery may kill more tumor cells than salvage surgery alone in patients with PD-L1 positive locally recurrent or persistent head and neck squamous cell carcinoma.

Testing Immunotherapy Versus Observation in Patients With HPV Throat Cancer

This phase III trials studies whether maintenance immunotherapy (nivolumab) following definitive treatment with radiation and chemotherapy (cisplatin) result in significant improvement in overall survival (time being alive) and progression-free survival (time being alive without cancer) for patients with intermediate risk human papillomavirus (HPV) positive oropharynx cancer (throat cancer) that has spread to nearby tissue or lymph nodes. Drugs used in chemotherapy 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. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. 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. It is not yet known whether chemotherapy and radiation therapy followed by maintenance nivolumab therapy works better than chemotherapy and radiation therapy alone in treating patients with HPV positive oropharyngeal cancer.

Comparing Radiation Plus Cetuximab to Radiation Plus Chemotherapy in People With Head and Neck Cancer Who Cannot Receive Cisplatin

This phase III trial compares cetuxumab to chemotherapy, carboplatin and paclitaxel, with intensity modulated radiation therapy for the treatment of patients with head and neck cancer who are unable to receive cisplatin. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of cancer cells. This may help keep cancer cells from growing. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Intensity modulated radiation therapy is a type of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. This type of radiation therapy reduces the damage to healthy tissue near the tumor. It is not yet know if cetxiumab or chemotherapy, with intensity modulated radiation therapy works best for the treatment of patients with head and neck cancer who are unable to receive cisplatin.

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.

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.

Ipilimumab, Nivolumab, and Radiation Therapy in Treating Patients With HPV Positive Advanced Oropharyngeal Squamous Cell Carcinoma

This phase II trial studies the side effects and best dose of ipilimumab, nivolumab, and radiation therapy and how well they work in treating patients with advanced human papillomavirus (HPV) positive oropharyngeal squamous cell carcinoma. Immunotherapy with monoclonal antibodies, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving ipilimumab, nivolumab, and radiation therapy may work better in treating patients with HPV positive oropharyngeal squamous cell carcinoma.

De-Escalated Adjuvant and Definitive Radiation Therapy Informed by DART 2.0 ctHPV-DNA

This phase II trial examines the use of blood-based biomarkers is to help inform decision making for treatment and radiation therapy for patients with human papillomavirus (HPV) positive oropharyngeal squamous cell cancers. The standard treatments for head and neck cancers are radiation therapy with chemotherapy or surgery potentially followed by radiation therapy with or without chemotherapy. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. Giving chemotherapy along with radiation may kill more tumor cells. However, the cancer can recur or can spread to other parts of the body and all treatments can be associated with side effects. The purpose of this study is to evaluate a blood-based biomarker, using the NavDx testing device, for head and neck cancers in order to see if it can help improve selection of the intensity of treatment in order to best balance the side effects of treatment with the goal of decreasing cancer recurrence. This test could aid in early detection of recurrence and salvage therapy.

Blood Tests and Questionnaires in Studying Adherence to Preventative Swallowing Exercises in Participants With Metastatic Head and Neck Cancer

This trial uses blood tests and questionnaires to study how well participants with head and neck cancer that has spread to other places in the body adhere to swallowing exercises to prevent future disease. Using blood tests to study cytokines (proteins related to the immune system) may help doctors learn if certain levels of cytokines affect whether or not side effects occur and if they put participants at risk for future disease. Questionnaires may help doctors learn about the reasons head and neck cancer participants may or may not follow the swallowing exercises that they are asked to perform after receiving radiation treatments.

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.

Evaluating a Decreased Dose of Radiation Therapy to the Elective Neck for the Treatment of HPV-Related Oropharyngeal Cancer, ENLIGHT Trial

This clinical trial evaluates how decreasing the dose of radiation to the elective neck (areas of lymph nodes not directly involved in the cancer) impacts treatment outcomes in patients with human papillomavirus (HPV)-related oropharyngeal cancer. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Radiation therapy plays an important role in the treatment of HPV-related oropharyngeal cancer, but it also causes significant toxicities. Given the significant toxicities associated with treatment, and the excellent outcomes of HPV-related oropharyngeal cancer, researchers are attempting to identify methods to de-escalate treatment for HPV-related oropharyngeal cancer in an effort to maintain excellent treatment outcomes while reducing the risk of toxicities. Reducing the dose of radiation therapy to the lymph nodes in the neck that aren't directly involved in the cancer may improve patient quality of life while still maintaining excellent rates of cure of disease.
