A Trial to Learn if Fianlimab and Cemiplimab Are Safe and Work Better Than Anti-PD1 Alone in Adult Participants With Resectable Stage 3 or 4 Melanoma
Recruiting
This study is researching an experimental drug called REGN3767, also known as fianlimab (R3767), when combined with another medication called cemiplimab (each individually called a "study drug" or called "study drugs" when combined) compared with cemiplimab alone. These types of immunotherapy study drugs are collectively known as immune checkpoint inhibitors. Immunotherapies are treatments that use the immune system to recognize and kill cancer cells. The study is focused on participants with a... Read More

Choosing Wisely: De-implementing Fall Prevention Alarms in Hospitals
Recruiting
This is a Hybrid II de-implementation study to reduce use of fall prevention alarms in hospitals. The intervention consists of tailored, site-specific approaches for three core implementation strategies: education, audit/feedback and opinion leaders. Hospital units will be randomized to low-intensity or high-intensity coaching for the implementation of the tailored strategies.

A Study of Nemtabrutinib Plus Venetoclax vs Venetoclax + Rituximab (VR) in Second-line (2L) + Relapsed/Refractory (R/R) Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL) (MK-1026-010/BELLWAVE-010).
Recruiting
The purpose of this study is to assess the safety and tolerability and to confirm the dose of nemtabrutinib in combination with venetoclax in participants with R/R CLL/SLL. The primary study hypotheses are that the combination of nemtabrutinib plus venetoclax is superior to VR with respect to progression-free survival (PFS) per 2018 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria as assessed by blinded independent central review (BICR).

Testing Shorter Duration Radiation Therapy Versus the Usual Radiation Therapy in Patients With High Risk Prostate Cancer
Recruiting
This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period of time. This trial is evaluating if shorter duration radiation preve... Read More

Sleep Architecture & Cognition in Focal Epilepsy
Recruiting
Focal Epilepsy (FE) patients and healthy controls will wear an actigraph at home for one week and a home sleep study device at home for one night. Participants will then undergo two nights of testing (at least one week apart) at California Sleep Solutions (CSS) in Sacramento, CA. During the overnight stays, participants will have EEG leads placed and possibly a headband. They will undergo cognitive testing before they go to sleep and again in the morning. During one night of testing, sounds will... Read More
