Glioblastoma adaptive, global, innovative learning environment or GBM AGILE trial is to identify effective therapies and improve survival for a type of brian cancer called glioblastoma (GBM) and to match effective therapies with adult patients with newly diagnosed or recurring glioblastoma. Eligible participants will have a 50/50 chance of taking either standard therapy medications or a medication not yet approved by the FDA called regorafenib during their standard of care treatment for GBM.

This study is for patients with rare Central Nervous (brain or spine) tumors. The purpose of this study is to determine whether the experimental drug, nivolumab can shrink tumors in patients with rare Central Nervous System (brain or spine) tumors or increase the time it takes for these tumors to grow or spread throughout the body.

This study will compare WATCHMAN FLXTM ("DEVICE") to a category of OAC called non-vitamin K antagonist oral anticoagulation, also known as NOACs ("CONTROL"). NOAC medications include Pradaxa® (dabigatran), Eliquis® (apixaban), Xarelto® (rivaroxaban), or Savaysa® (edoxaban).The study will research the safety and effectiveness of the WATCHMAN FLXTM device compared to treatment with NOAC therapy to determine if it works for patients with your type of atrial fibrillation who require treatment for potential blood clot formation (thrombus) in the LAA.

The PK Papyrus Covered Coronary Stent System is a Humanitarian Use device (HUD) approved for the use of acute perforation in native coronary vessels or coronary bypass grafts in vessels 2.4-5.0mm in diameter. In an emergency situation, PK Papyrus may be used emergently outside its' approved indications if a patient has a life threatening condition that needs immediate treatment and no generally acceptable alternative treatment for the condition exists.

This is a prospective observational cohort study that will create a patient registry by collecting data on patients who receive REBYOTA to prevent recurrence of Clostridioides difficile infection (CDI). The registry will include data about CDI episodes, CDI related symptoms, healthcare resource utilization (i.e., hospitalizations and re-admissions) and this data will be collected up to 6-months after receiving REBYOTA™.

This is a study comparing the new class anticoagulants factor XIa to the FDA approved Apixaban. The study is to determine if Milvexian is as effective and safe with preventing clots for patients with A-fib and to determine if Milvexian is better at reducing the chances of bleeding.

This research is being done to assess whether it is safe and effective to stop oral anticoagulation medications (a blood-thinning medication) during prolonged periods of normal heart rhythm in participants with infrequent episodes of atrial fibrillation (AF).

You may qualify for this study if you have a history of atrial fibrillation (AF) and are currently taking an oral anticoagulant (a blood-thinning medication). You will be randomized to one of two groups: Control Group or Study Intervention Group.

If you are randomized to the Control group, you will be asked to stay on your previously prescribed oral anticoagulant. If you are randomized to the Study Intervention group, you will be asked to take the oral anticoagulant for 30 days only if a prolonged episode of AF is detected on an AF-sensing Apple smartwatch you will be provided.

This phase I trial will determine the maximum tolerated dose of lenalidomide when given in combination with high-dose systemic methotrexate and rituximab, with or without nivolumab, as induction treatment of primary central nervous system lymphoma. In addition, whether the combination of drugs can extend the control of CNS lymphoma by being used as maintenance (prolonged treatment) after control is achieved with the initial chemotherapy regimen (induction) will be judged. If decided to take part in the study, participants will complete pre-study testing, and if allowed to participate in study different people will get different doses of the study drug lenalidomide during induction chemotherapy. If the drug does not cause serious side effects, the next group of people in the study will get a higher dose, and the doses will continue to increase for every new group until people have serious side effects that require the dose to be lower. Lenalidomide will be taken by mouth on days 5 to 14 of each induction cycle. Once the dose of lenalidomide is found, the next group of people in the study will receive nivolumab in combination with the other drugs (methotrexate, rituximab, and lenalidomide). The first drug administered in each cycle is rituximab, which is given as an intravenous infusion typically in the infusion center. The day after rituximab, participants will be admitted to the hospital for the infusion of methotrexate. Enrolled participants that present benefit after induction will receive lenalidomide and nivolumab as prolonged therapy (maintenance) for an additional 12 months (12 cycles and each cycle is 28 days) or until the disease gets worse or the side effects become too severe. After treatment is completed the study doctor will continue to follow up on participants condition for 2 years to observe side effects. After 2 years the doctor will continue to follow up either in clinic or by phone for up to 5 years after registration. The most common side effects known are kidney damage, infusion reaction, blood clots, birth defects, immune toxicity, fever and infections, and there may be some risks that the study doctor is not aware of yet. Once the combination is proven safe, this study will allow for future studies to determine whether the combination of these four drugs can improve the response to treatment and help increase the understanding of their use in primary CNS lymphoma treatment. It is unclear whether these drugs will help participants live longer than the usual approach alone.
