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 advanced solid tumors. This study is testing an investigational drug called BNT317. "Investigational" means it has not been approved by the United States Food and Drug Administration (FDA). The primary purpose of this study is to evaluate the safety, tolerability, absorption of BNT317. BNT317 is administered via intravenous (IV) infusion. Participants can continue to receive this study drug until it no longer gives them benefit. Researchers will continue to follow-up with patients long-term.

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 subjects who has been diagnosed with radioactive iodine refractory (RAIR) differentiated thyroid cancer. Subjects are expected to remain in the study for a minimum of 96 months. Drugs are FDA approved and is given in the form of Tablet to subjects. The procedures include urine protein test, CT, MRI. Risks include diarrhea, nausea, vomiting, tiredness, weight loss, loss of appetite, changes in taste, redness, pain or peeling of palms and soles, High blood pressure. There is evidence that dabrafenib, trametinib and cabozantinib are effective in stabilizing and shrinking the type of cancer, we do not know which of these approaches are better at prolonging time until tumor growth. However, information learned from the trial may help other people in the future.
