T cell therapy to help prevent COVID-19 after transplant
This Phase 1 trial tests a donated immune-cell treatment (T cells) to help immunocompromised people fight or resist COVID-19 after they recently received a bone marrow or stem cell transplant. It aims to see if the treatment is safe and if it helps the body respond better to the virus.
Washington D.C., District of ColumbiaAges 2–80 - NCT02735707RecruitingPhase 3
Adaptive trial for severe pneumonia care in intensive care
This study tests ways to improve treatment for adults with severe pneumonia that lands them in the ICU, adjusting the plan as results come in. It may help your care team find better treatments for lung infection and breathing/heart support needs.
