Can a lower dose of antibiotics prevent pneumonia just as well after kidney transplant?
NCT ID NCT07619027
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a lower dose of the antibiotic TMP-SMX works as well as the standard dose to prevent a serious lung infection called PJP in people who have just had a kidney transplant. About 1,084 adult first-time kidney transplant recipients will take either a low or standard dose daily for 12 months. Researchers will track who gets PJP and any side effects over 24 months.
