Trial to reduce HIV reservoirs aiming for treatment-free remission
This study tests whether a combination approach, including a drug called nicotinamide (a form of vitamin B3) and other strategies, can reduce the hidden HIV reservoir enough to allow a temporary pause in antiretroviral therapy without the virus rebounding. It is for people who have well-controlled HIV and strong immune systems.
São Paulo, São PauloAges 18–65 - NCT06812598Recruiting
Extended letermovir to prevent CMV after stem cell transplant
This trial tests whether taking letermovir for a longer time can prevent CMV (a common virus) from reactivating in adults with certain risk factors after a donor stem cell transplant. If you're preparing for your first transplant and have a high-risk donor or conditioning, this study may be an option.
Suzhou, JiangsuAges 18 years+ - NCT06808451Recruiting
Comparing DNA test vs. standard culture for UTI diagnosis
This study compares two ways to diagnose urinary tract infections: a newer DNA test (PCR) versus the standard urine culture. The goal is to see if the DNA test finds infections faster and more accurately, so you can get the right treatment sooner.
Cleveland, OhioAges 18 years+ - NCT06808100Enrolling by invitation
Can a blood test predict organ failure in septic shock?
This trial is studying a blood marker called GDF-15 to see if it can predict which patients with septic shock might develop multiple organ failure. If you have septic shock and do not have certain other serious health conditions, you may be able to join.
AnkaraAges 18 years+ - NCT06811025Enrolling by invitationPhase 1/Phase 2
Contezolid for treating tuberculous meningitis
This trial tests a new antibiotic called contezolid for people with tuberculous meningitis, an infection of the brain lining. The goal is to see if it works well and is safe.
Beijing, Beijing MunicipalityAges Any age - NCT06811935Recruiting
PEDI Study for Kids with PANS or PANDAS
This study looks at children who may have PANS or PANDAS, conditions that can cause sudden changes in behavior or mood after an infection. It aims to better understand these conditions and improve care.
Lebanon, New HampshireAges 3–17 - NCT06812065Recruiting
Heat and hydrogen peroxide for skin warts
This trial tests whether applying heat combined with a common disinfectant (hydrogen peroxide) can safely and effectively remove viral skin warts. It may be an option if you have common, plantar, or genital warts and are between 16 and 65 years old.
Shenyang, LiaoningAges 16–65 - NCT06811012Enrolling by invitationPhase 1/Phase 2
Testing Contezolid for Bone and Joint Tuberculosis

Beijing, Beijing MunicipalityAges Any age - NCT06809413Enrolling by invitationPhase 2
Testing a new antibiotic for mycobacterium abscessus lung infection
This study tests if a drug called sitafloxacin can quickly kill mycobacterium abscessus bacteria in the lungs. It may help people with this hard-to-treat infection find a more effective treatment.
Beijing, Beijing MunicipalityAges 18–65 - NCT06808776Recruiting
