A Phase 3 Randomized, Open-label Study of MK-5684 Versus Alternative Abiraterone Acetate or Enzalutamide in Participants With Metastatic Castration-resistant Prostate Cancer (mCRPC) Previously Treated With Next-generation Hormonal Agent (NHA) and Taxane-based Chemotherapy (OMAHA-003) (OMAHA-003)
This trial is testing MK-5684 in men with metastatic castration-resistant prostate cancer (mCRPC) previously treated with next-generation Hormonal Agent (NHA) and Taxane-based chemotherapy. This trial will compare MK-5684 to abiraterone acetate and enzalutamide. Abiraterone acetate and enzalutamide are standard treatments for mCRPC. The purpose of this trial is to test the safety of the trial drug, MK-5684, see how well the drug works, and see how the body handles the drug. We also want to see if participants who get MK-5684 live longer compared to those who get abiraterone acetate or enzalutamide.

A Pivotal Study Evaluating Safety and Efficacy of the ShiraTronics Migraine Therapy System in RELIEVing, Interrupting, and Preventing Chronic Migraine (RELIEV-CM2)
This research study is testing a potential new treatment for refractory chronic migraine (RCM). The potential new treatment is called ShiraTronics Migraine Therapy.

MT2022-27: TRANSPIRE: Lung Injury in a Longitudinal Cohort of Pediatric HSCT Patients
People planning to undergo a bone marrow transplant and are at risk for developing problems with the lungs related to this planned therapy. The types and seriousness of lung problems that may develop after transplant can be very different and currently, we don’t exactly know what risk factors influence who develops them or how they may respond to therapy. Also, we do not know what the best test is to monitor lung function after transplant, especially in children and young adults. The purpose of this study is to help investigators learn more about lung problems after bone marrow transplant including what is the best method for diagnosing lung problems and following how well the lungs are working. In this study, clinical information, laboratory results and imaging findings will be collected from medical records to assist researchers in learning more about lung complications after bone marrow transplant.

Vestibular and Cortical Contributions to Transitions in Freezing of Gait and Parkinson's Disease
This study will examine the brain activation associated with the transition between movements in Parkinson’s disease, and if these changes are related to the development of problems with moving (like freezing of gait) and thinking. We will look at brain activity associated with the vestibular (inner ear) and cortical (surface of the brain) systems. People with Parkinson’s disease (especially people with freezing of gait) sometimes have difficulty initiating changes in movement types, such as going from standing to walking, turning, or switching between slow and fast repetitive movements. The difficulty in movement transitions may be associated with an overactive vestibular system (inner ear) or cortical system. In each experiment in this study, we expect about 20-25 participants with Parkinson’s disease and freezing of gait, 20-25 participants with Parkinson’s without freezing of gait, and 20-25 control participants
