This is a study that looks at the use of anti-platelet therapy and chemotherapy in patients with recurrent or metastatic squamous cell carcinoma of the head and neck (HNSCC). Anti-platelet therapy is the use of drugs that reduce the blood's ability to form clots. The overall goal of this study is to see if this therapy combination can increase the body's ability to fight the disease.

This study is for patients that have been diagnosed with with resectable High-risk Locally Advanced Cutaneous Squamous Cell Carcinoma (LA cSCC). The investigational drug used in this study is Pembrolizumab. The purposes of this study are to: determine how well pembrolizumab keeps the cancer from coming back or spreading as compared to placebo, determine if giving pembrolizumab after surgery and radiation helps patients live longer, and to test the safety of the study drug and see how patients' bodies handle it. Participants can expect to be in this study for about 8 years. This includes the time that participants will be on study drug and in follow up to see if the cancer has come back or spread.

This study is for patients that have been diagnosed with advanced or resistant skin cancer (melanoma), non-melanoma skin cancer (NMSC), non-small cell lung cancer (NSCLC), certain types of solid tumors, or bladder cancer (UBC). The investigational drug in this study is RP1. RP1 is a herpes simplex virus (a microscopic life form commonly known as the "cold sore virus") that has been genetically changed to grow in and destroy cancer cells. This treatment will be injected directly into tumors. The purpose of this study is to test the safety and how well RP1 works when it is injected into certain types of solid tumors in combination with another cancer drug, called nivolumab. Participants can expect to be in this study for about 2 to 3 years.

This study is for patients who have been diagnosed with head and neck squamous cell carcinoma (HNSCC) that has returned (recurrent) or spread after previous treatment (metastatic). The investigational drug in this study is lenvatinib. The study will also use lenvatinib in combination with pembrolizumab, which is also experimental. The purposes of this study are to: test the safety of the study drugs, lenvatinib alone, pembro and lenvatinib together, and standard chemotherapies alone in the treatment of HNSCC; see how well the combination of pembro and lenvatinib works, compared to standard chemotherapies; and see if participants who get pembro and lenvatinib live longer than those who are treated with standard chemotherapies. Participants can expect to be on this study for about 48 months.

This study is for patients who have been diagnosed with Head and Neck Cancer that spread to sites distant from the head and neck region (metastatic) or for cancer that returned or got worse after being treated (recurrent), and test positive for High-risk Human Papillomavirus-16 (HPV16) Infection.

The investigational vaccine in this study is called PDS0101. "Investigational" means the study vaccine being tested has not been approved by the United States Food and Drug Administration (FDA). The purpose of this research is to find out if the combination of the investigational vaccine, given by subcutaneous (beneath the skin) injection and the standard of care, Pembrolizumab (KEYTRUDA®), given by IV, are effective and safe. The PDS0101 vaccine designed to boost the body's immune response against HPV 16.Participants can expect to receive treatment for about 2 years. Each person who agrees to take part in the study will be asked to come in for a minimum of 18 cycles and a maximum of 35 cycles.

This study is for patients who have advanced cancers, such as head and neck cancer, colorectal cancer, breast cancer, and others. This study is testing a new treatment for these types of cancer. The new test drug is called BCA101. Pembrolizumab is an approved drug by the United States Food and Drug Administration (FDA) for the diseases described in this study and will be used as approved. The type of cancer a patient has will determine whether he/she will get BCA101 alone or BCA101 in combination with pembrolizumab. Participants will receive either BCA101 alone, BCA101 in combination with pembrolizumab or BCA101 and enforafenib, depending on your cancer until the cancer gets worse, they experience bad side effects, or until they withdraw consent, or until the Investigator considers it is in his/her best interest to discontinue the study drug.

This study is for subjects that have been diagnosed with advanced cancer. The purpose of this study is to find subjects with advanced cancer that had an exceptional disease response (improvement) while being treated with standard immunotherapy agents. This study will monitor their progression through a series of blood draws. Subjects will either continue immunotherapy or have completed immunotherapy. Participation in the study will take about 6 visits over a period of about 2 years. During this time the study team will follow your care by clinic visit, phone contact and/or medical record review every three months to collect information on the status of your cancer. This is not a treatment study.

This study is for patients that have been diagnosed with locally advanced head and neck squamous cell carcinoma. The purpose of this research study is to evaluate the effectiveness of using a combination of pembrolizumab and olaparib when given before and after standard chemoradiation therapy in treating locally advanced head and neck squamous cell carcinoma. Pembrolizumab and olaparib are drugs that are approved for treatment of different cancers including lung, head and neck, breast and prostate cancer. However, FDA has not approved use of these two drugs together in treating head and neck cancer.

Treatment will be offered in three phases. In the induction phase, participants will receive a single infusion of pembrolizumab and will take olaparib tablets twice daily for total of 21 days. Participants will move to the chemoradiation phase, where they will receive radiation therapy and chemotherapy per routine standard care, for a total of 7 weeks. Chemoradiation therapy is done on a daily basis (excluding weekends), and chemotherapy therapy will involve a cisplatin infusion once weekly. At the conclusion of this phase, participants start the maintenance phase, which involves treatment with pembrolizumab and olaparib in cycles that are 42-days long. Treatment will include a single pembrolizumab infusion during each cycle and taking olaparib tablets twice daily during each cycle. Total number of cycles to be completed in the maintenance phase are 8 cycles. Participants can expect to be in this study for about 6.5 years.

This study is for men and women with HER2-positive salivary gland cancer (SGC) that has come back, spread outside of their salivary gland, or cannot be removed by surgery. This study is being done to find out if ado-trastuzumab emtansine (T-DM1) extends the length of time without the cancer getting worse compared to the usual approach.

This study is enrolling subjects with advanced solid tumors with the TP53 Y220C alteration in cancer cells. This alteration is a mutation of the tumor that can be found through laboratory tests that use a sample of tissue, blood, or other fluids to check for signs of cancer. This study involves research testing the safety, best dose, side effects and timing of the study drug called PC1486. You will take the study drug, PC14586, in the form of a tablet. If assigned to the combination treatment arm (Part 1), you will also be given pembrolizumab as an intravenous (IV) infusion. Pembrolizumab is a type of immunotherapy that is FDA approved to treat your kind of cancer. The study drug PC1486 is not approved by the Food and Drug Administration (FDA). This study drug targets the TP53 Y220C genetic alteration in tumor cells. During the pre-screening portion, participants will provide either archived tissue or a fresh tumor sample to test for the genetic alteration. If the participants show the genetic tumor alteration in the cancer cells, they may be asked to participate in the trial. Treatment arms are groups or subgroups of participants in a clinical trial. This study will have two arms: one studies PC1486 alone and the second arm studies PC1486 in combination with Pembrolizumab against advanced solid tumors. PC14586 is a small molecule (chemical) that is designed to act on the genetic alteration TP53 Y220C in cancer cells to slow the growth of cancer, and it is taken orally. This study involves blood tests, a possible tumor biopsy, CT, and MRI scans. The study will last approximately 6 months of treatment, followed up by a check-up after the first 3 weeks and every 3 months after. Some common risks (observed in greater than 20% of people) include: Nausea, Vomiting, Abnormal liver tests, Abnormal kidney test (possible kidney damage
