This phase II/III study purpose is to see if neck and shoulder function and pain are better after sentinel lymph node (SLN) biopsy surgery compared to the usual approach and to see if SLN biopsy surgery is as good as the usual approach in extending your time without cancer. If decided to participate in this study participants will go through a pre-treatment period to determine if they are eligible for the study including a PET/CT scan to determine if their cancer has spread. They will also receive a quality of life questionnaire to determine their physical well-being. Participants will complete these questionnaires 5 times: before surgery; at 3 weeks after surgery; and at 3, 6 and 12 months after surgery. If their cancer has not spread participants will be randomized to receive SLN or the SOC Elective Neck Dissection (END) to remove their cancer/lymph nodes during the treatment period. Following treatment, participants will enter the follow-up period and the study doctor will continue to follow participates condition and watch for side effects of the surgery. Participants will visit in the clinic at 3 weeks after surgery, then every 3 months for the first year, then every 4 months for the second year, then every 6 months for the third year, then yearly for their lifetime. The study duration for the phase II portion is about 37 months (~3.1 years) and around 132 months (11 years) for the phase III portion. The main risk associated with this study are leakage of lymph fluid called "chyle" into the neck, nerve injury and shoulder movement problems, swallowing difficulty, lung infection, and bleeding. There is evidence that the SLN biopsy technique causes less shoulder and neck movement problems and pain, and is effective in removing your cancer. It is not possible to know now if the SLN biopsy approach will be as good at extending your time without disease compared to the usual END approach. This study will help the study doctors learn things that will help people in the future.

This study is designed to learn more about how nivolumab and ipilimumab, with or without cabozantinib effects the growth and spreading of head and neck cancer. If decided to take part in this study, participants will go through a screening period, treatment period, and follow-up period. During the screening period following signing of consent form participants will be evaluated for screening criteria and determined if they qualify for the study. During treatment period participants will be randomly assigned to either receive the combination of two immunotherapy drugs, nivolumab and ipilimumab for up to 2 years, or the two immunotherapy drugs with an additional targeted drug, cabozantinib, for up to 2 years unless your cancer gets worse or the side effects of the treatment become too severe. In the follow up period the side effects will be observed by the study team every 3 to 4 months for 2 years after treatment. The most common risks and discomforts expected in this study are diarrhea, nausea, vomiting, tiredness, weight loss, loss of appetite, changes in taste or voice, redness, pain or peeling of palms and soles, and high blood pressure which may cause blurred vision. There may not a benefit from joining the study. The head and neck cancer may improve while on this study but it may not, and it may even get worse. It will also help inform how well this combination treatment works at curing this type of cancer. The study results may be used to help others in the future.

The primary objective of this study is to demonstrate the safety and effective use of Stryker's PEEK Customized Implants in patients receiving craniofacial (head and facial) surgery. Other objectives include using a CT scan to assist surgeons with providing a solution to complex and simple reconstruction challenges and reducing them to a single or two-stage procedure, thereby minimizing the overall surgery time and limiting the number of surgeries. Patient questionnaires and health information will be used during the study to demonstrate the safety and effectiveness of the implants. We will be enrolling ages 4 - 75 years old.

This phase III study evaluates whether a new drug, dostarlimab, can delay or reduce the risk of cancer returning when administered for a year, shortly after receiving a combination of radiotherapy and chemotherapy (CRT). This study will enroll adults diagnosed with head and neck cancer who are treated with CRT. This study is divided into three parts: the screening period begins shortly after CRT and lasting 4-6 weeks where tests will be conducted to determine eligibility, followed by a 12-month treatment period where participants will receive either dostarlimab or an inactive substance (salt solution) with no effect on your body (placebo), and a follow up period when they will continue to be assessed to see if their cancer has returned or gotten worse. Participants may be on the study for approximately up to 5 years in total. The main risks are anaemia, nausea, vomiting, and diarrhea. Alternatives to this treatment is standard of care CRT because for this type of head and neck cancer, at the present time, there are no other approved therapies administered shortly after CRT that may prevent or delay the return of the cancer. The study benefit is dostarlimab may help slow or stop the growth of your cancer.

This study is designed to learn more about the effects of Petosemtamab, an investigational drug not FDA approved, compared to standard of care treatment for people with head and neck cancer that has been previously treated with immunotherapy and chemotherapy. If decided to take part in this study, participants will go through a screening period, treatment period, and follow-up period. During the screening period following signing of consent form participants will be evaluated for screening criteria and determined if they qualify for the study. During treatment period participants will be randomly assigned to either receiving petosemtamab or one of the three standard of care choices. In the follow up period the side effects after completion of petosemtamab administration or assigned standard of care treatment will be evaluated. Also, approximately every 12 weeks after study treatment stopped, either petosemtamab or assigned standard of care, participants will receive a phone call for long term follow-up for up to 1.5 years. Participation in this study may last up to two years. The participants will complete questionnaires to evaluate the differences in the quality of life for participants that received petosemtamab versus standard of care treatment. Some serious risk related to this study are infusion related reactions, rash and diarrhea. There may not a benefit from joining the study. The head and neck cancer may improve while on this study but it may not, and it may even get worse. It will also help inform how well Petosemtamab works at curing this type of cancer. The study results may be used to help others in the future.

The purpose of this study is to evaluate investigational treatments (study drug) in people with recurrent or metastatic PD-L1-positive, HPV-negative head and neck squamous cell carcinoma without prior treatment. The goal is to determine the optimal dose level, safety, and tolerability for the study drug BCA101. This is a phase 2 study; BCA101 is not FDA approved by the U.S. Food and Drug Administration (FDA). Treatment for this study may be up to 5 years. The procedures include taking study drug intravenously, blood and urine samples, and CT scans. Risks include diarrhea, nausea, vomiting, mouth sore, nose bleed, headache, and skin rash. You may or may not receive a direct benefit from participating in this trial, however, information learned from the trial may help other people in the future.

This study is for patients that have been diagnosed with recurrent, progressive as well as advanced, metastatic hepatocellular carcinoma (HCC), cervical cancer (CC), melanoma, head and neck squamous cell carcinoma (HNSCC) or non-small cell lung cancer (NSCLC). The study is testing an investigational drug called DB-1311. Investigational means it has not been approved by the United States Food and Drug Administration (FDA). The primary purpose of the study is to determine the recommended phase II dose of DB-1311 in combination with BNT327 or DB-1311 in combination with DB-1305 by assessing the safety and tolerability. The drug is given to participants by IV infusion. Participants in this study can expect to be in this study for 72 months.

The purpose of this study is to test the effectiveness and safety of the combination of an investigational vaccine, PDS0101, given by subcutaneous (beneath the skin) injection and the standard of care, Pembrolizumab (KEYTRUDA), given intravenously ("IV;" into the vein) compared to pembrolizumab (KEYTRUDA) alone for those with unresectable recurrent or metastatic head and neck cancer and high risk papillomavirus infection. "Investigational" means the combination of the study vaccine and pembrolizumab being tested has not been approved by the US Food and Drug Administration (FDA) nor any other Health Authority.

This study is for adult patients with head and neck cancer who are at risk of recurrence. The purpose of this study is to evaluate whether the use of Indocyanine Green (ICG) dye allows for better identification of tumor tissue during surgical procedures. Participation will include standard of care visits along with administration of ICG dye and imaging during surgery. Participation in this study will last approximately 6 weeks.
