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 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 SAR444245 (THOR-707). Investigational means the drug is not approved by the Food and Drug Administration (FDA).

The main purpose of this research study is to determine the antitumor activity of SAR444245 in combination with other approved anticancer therapies.

Participants will have blood draws, CT and/or MRI scans, and receive study drug in a vein (IV). There are risks to the study drug including fever, influenza-like illness, vomiting, nausea, and chills. It is possible that participant's symptoms will improve, but that cannot be guaranteed.

Screening will take up to 28 days. If participants receive treatment for the maximum amount of cycles, they will receive treatment for about 2 years. The end of treatment visit will be about a month after the last treatment is received. Then, participants will have in clinic observational visits every 3 months until disease progression, a new cancer therapy is started or 9 months from the date of first infusion of the last participant. Then, follow up visits by phone every 3 months for about 3 years. Total participation will last about 6 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 Buparlisib (AN2025) that will be given in combination with Paclitaxel (an approved drug). The study will also use alone.

The main purpose of this research study is to assess the effectiveness and safety of once-daily buparlisib in combination with weekly paclitaxel compared to weekly paclitaxel alone head and neck cancer that has progressed after prior immunotherapy (treatment that uses your immune system to attack your cancer, such as antiPD1/antiPDL1 treatments) with or without prior platinum-based chemotherapy. Participants can expect to be on this study for about 5 years.

This study is for participants that have a solid tumor that hasn't responded to previous treatment or has spread to other parts of the body (metastatic), including ovarian, cervical, endometrial, head and neck, squamous cell lung, kidney, prostate, colorectal, gastric, breast, bladder cancer, lung adenocarcinoma, or melanoma. This research study is for the investigational drug called TTX-080. This drug has not been approved by the United States Food and Drug Administration (FDA). This purpose of this study is to see what effects TTX-080 has on tumors. TTX-080 may help the immune system attack cancer cells. The study drug is given intravenously (into the vein). It is expected that participants could be in the study for about 2 years and will depend on how he/she tolerate the study drug. Participants may experience certain side effects and discomforts from taking TTX-080. Because the study drug is experimental, all the side effects may not be known.

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 patients that have a tumor that cannot be removed through surgery (unresectable) or may have spread (metastasized) to other parts of their body. In this study, ASP1951 will be given alone (monotherapy) or combined with pembrolizumab (combination therapy). Both ASP1951 and pembrolizumab will be considered study drug. Pembrolizumab has been approved by FDA for use in patients with skin, lung, cervical cancer, certain cancers of head and neck and other cancers but may not be approved to treat all types of cancer. However, the use of ASP1951 plus pembrolizumab has not been approved by regulatory authorities and is therefore investigational. The study consists of 3 periods: screening (up to 28 days), treatment (up to 48 weeks [16 cycles]) and follow up (up to 45 weeks), followed by an optional re-treatment period for participants that qualify. The re-treatment period will allow participants to receive study drug treatment again for up to 16 additional cycles (approximately 48 weeks), for a maximum total treatment and re-treatment period of 32 cycles (approximately 96 weeks). Both study drugs are administered intravenously (into the vein).This is the first time the investigational study drug ASP1951 is being tested in humans; however, studies in animals showed that the study drug is safe to be tested in humans.

This study is for patients that have been diagnosed with locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). The investigational drug used in this study is Debio 1143. The main purpose of this study is to learn how well the study medicine works and how safe the study medicine is compared with placebo. A placebo is an inactive substance that looks like the study medicine but does not contain any active study medicine. Participants can expect to be in this study for up to 7 years. Participation will consist of approximately 56 visits at the study center over a period of 5 years, followed by telephone calls every 6 months over a period of maximum 2 years.

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 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 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.
