Studies of the Pathogenesis of HIV Infection in Human Peripheral Blood Cells and/or Body Fluids in People Living With and Without HIV
NCT00001281
Recruiting
We are studying virologic and/or immunologic parameters of HIV infection and other infectious or non-infectious immune deficiency diseases in order to better understand the pathogenesis of HIV. Because of the lack of an adequate animal model it is generally necessary to utilize human peripheral blood cells for studying aspects of either in vivo or in vitro HIV infection. We wish to be able to continue to elucidate many pathogenic aspects of HIV infection in relation to other infectious or non-in... Read More

Study of Intralesional Cemiplimab in Adult Patients With Early Stage Cutaneous Squamous Cell Carcinoma
NCT06585410
Recruiting
This study will test a study drug called cemiplimab to see if it can help treat early-stage cutaneous squamous cell carcinoma (CSCC), a type of skin cancer. Cemiplimab works by helping the immune system to kill cancer cells. It binds to a protein called programmed cell death-1 (PD-1) on the surface of certain immune cells. The main purpose of this study is to compare how well cemiplimab works compared to surgery, when injected into the lesion. The study is looking at: * The side effects cemip... Read More
