This phase III trial compares the effect of adding cemiplimab to standard therapy (surgery with or without radiation) versus standard therapy alone in treating patients with stage III/IV squamous cell skin cancer that is able to be removed by surgery (resectable) and that may have come back after a period of improvement (recurrent). The usual treatment for patients with resectable squamous cell skin cancer is the removal of the cancerous tissue (surgery) with or without radiation, which uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. 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. Cemiplimab has been approved for the treatment of skin cancer that has spread or that cannot be removed by surgery, but it has not been approved for the treatment of skin cancer than can be removed by surgery. Adding cemiplimab to the usual treatment of surgery with or without radiation may be more effective in treating patients with stage III/IV resectable squamous cell skin cancer than the usual treatment alone.

This study is exploring the use of Panitumumab in Head and Neck Cancer. Panitumumab is an approved drug named Vectibix and is used as an anti-cancer agent in other cancers such as colorectal cancer. It works by attaching to the cancer cell in a unique way that allows the drug to get into the cancer tissue. In addition to the Panitumumab, participants will also receive a Panitumumab-IRDye800 (Pan800) or a fluorescently labeled Panitumumab infusion. IRDye800 is an investigational dye that, when tested in the lab, helps various characteristics of human tissue show up better when using a special camera during surgery. Panitumumab-IRDye800 is a combination of the drug and the dye that attaches to cancer cells and appears to make them visible to the doctor when he or she uses the special camera during surgery.

The goal of this study is to use a novel and possibly safer approach to identify an optimal dose for panitumumab to treat cancer patients by using a new light-based therapy. In this study, different drug levels will be analyzed using this approach to understand how much drug reaches the tumor at different administered doses, which may help us provide safer and/or more effective therapies in the future.

The goal is to identify the correct amount or dose of a drug that is needed for effective cancer therapies. Often, clinical studies look at how much of the drug can be tolerated before patients become sick, rather than how much of the drug is required to be effective.

IRDye800 is an investigational dye that, when tested in the lab, helps various characteristics of human tissue show up better when using a special camera during surgery. Panitumumab-IRDye800 is a combination of the drug and the dye that attaches to cancer cells and appears to make them visible to the doctor when he or she uses the special camera during surgery. This will help the surgeon with clinical margins during surgery and will may have a clearer way to differentiate between cancer and healthy tissue.

This phase II trial studies the effect of pembrolizumab alone compared to the usual approach (chemotherapy \[cisplatin and carboplatin\] plus radiation therapy) after surgery in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or patients with a second head and neck cancer that is not from metastasis (primary). Radiation therapy uses high energy radiation or protons to kill tumor 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. Carboplatin is also 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. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab alone after surgery may work better than the usual approach in shrinking recurrent or primary head and neck squamous cell carcinoma.

The goal of this clinical trial is to evaluate the safety of TOS-358 in adults with select solid tumors who meet study enrollment criteria. The main questions it aims to answer are:

1. what is the maximum tolerated dose and recommended dose for phase 2?
2. how safe and tolerable is TOS-358 at different dose levels when taken orally once or twice per day?

This study is researching an investigational drug called marlotamig (REGN7075) by itself and in combination with cemiplimab with or without chemotherapy. The study is focused on patients with certain solid tumors that are in an advanced stage.

The aim of the study is to see how safe and tolerable marlotamig is by itself and in combination with cemiplimab (with or without chemotherapy), and to find out what is the best dose of marlotamig to be given to patients with advanced solid tumors when combined with cemiplimab (with or without chemotherapy). Another aim of the study is to see how effective marlotamig by itself, or in combination with cemiplimab (with or without chemotherapy), is at treating cancer patients.

The study is also looking at:

* Side effects that may be experienced by people taking marlotamig by itself and in combination with cemiplimab with or without chemotherapy
* How marlotamig works in the body by itself and in combination with cemiplimab with or without chemotherapy
* How much marlotamig is present in the blood when given by itself and in combination with cemiplimab with or without chemotherapy
* To see if marlotamig by itself and in combination with cemiplimab with or without chemotherapy works to treat cancer by controlling the proliferation of tumor cells to shrink the tumor
* Whether the body makes antibodies against the study drugs (marlotamig and cemiplimab) (which could make the drug less effective or could lead to side effects)

This is a Phase 1, open-label, first-in-human, dose-escalation and expansion study of CHS-114, a monoclonal antibody that targets CCR8, as a monotherapy in patients with solid tumors.

An Open-label, Phase I Dose Escalation and Phase 2 Dose Expansion Study to Assess Safety, Tolerability, Preliminary Antitumor Activity of SMP 3124LP in Adults with Advanced Solid Tumors

The purpose of the study is to assess the safety and efficacy of inavolisib as a single-agent and in combination with atezolizumab in participants with phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha isoform (PIK3CA)-mutated cancers, including previously treated head and neck squamous cell carcinoma (HNSCC).

This is a study to establish a safe and feasible dose for prophylactic use of a combination of gabapentin and ketamine in head and neck cancer patients undergoing chemoradiation.

This ComboMATCH patient screening trial is the gateway to a coordinated set of clinical trials to study cancer treatment directed by genetic testing. Patients with solid tumors that have spread to nearby tissue or lymph nodes (locally advanced) or have spread to other places in the body (advanced) and have progressed on at least one line of standard systemic therapy or have no standard treatment that has been shown to prolong overall survival may be candidates for these trials. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with some genetic changes or abnormalities (mutations) may benefit from treatment that targets that particular genetic mutation. ComboMATCH is designed to match patients to a treatment that may work to control their tumor and may help doctors plan better treatment for patients with locally advanced or advanced solid tumors.
