Blood and tumor study for virus markers in throat cancer
This study looks at virus-related markers and tiny gene regulators (microRNAs) in tumor tissue from people with certain throat cancers caused by human papilloma virus (HPV). It’s observational, meaning it does not change your treatment, but results may help doctors better understand these cancers and how they behave.
RomeAges 18 years+ - NCT06076200Recruiting

Probiotic drops for very preterm babies in Scandinavia
This trial studies whether giving probiotic supplements to extremely preterm newborns helps improve health outcomes. It’s meant for babies born very early, and the results could help guide safer early nutrition and care.
Solna, Stockholm CountyAges 5 months–6 months - NCT06088745RecruitingPhase 3
Shingles vaccine trial for adults 40+
This trial tests a new shingles vaccine to see how well it prevents shingles in adults aged 40 and older. It aims to help those who have not had shingles recently or been vaccinated against it before.
Zhenjiang, JiangsuAges 40 years+ - NCT04586413Recruiting
Help build and study a quality-of-life tool after COVID-19
This study will collect information from adults who had COVID-19 (confirmed by a test or diagnosis) to develop and improve a questionnaire about life after infection. Your answers may help researchers better track symptoms and quality of life over time.
OxfordAges 18 years+ - NCT04892654RecruitingPhase 3
Doravirine plus dolutegravir switch for people with HIV
This Phase 3 study tests whether switching from a three-drug HIV regimen to a two-drug regimen (doravirine plus dolutegravir) can keep your virus levels controlled. It may help people who are stable on their current treatment explore a simpler switch under close monitoring.
LondonAges 18 years+ - NCT06106698Recruiting
Washed microbiota transplant for C. diff infection
This trial tests a treatment called washed microbiota transplantation (WMT) for people with a C. diff infection that causes diarrhea. WMT uses processed donor bacteria to help restore healthy gut balance and fight the infection.
Nanjing, JiangsuAges 3–100 - NCT03932461Recruiting
Wound suction vs immediate re-operation for severe bowel infection
This trial compares two ways of treating the abdomen after emergency surgery when there is severe contamination from a bowel perforation causing widespread peritonitis. It may help find the safest approach to control infection and promote healing.
Odense, FynAges 19 years+ - NCT06122259Recruiting
Fever study in Guinea
This study is for people with a recent fever. Researchers want to learn more about what causes fevers in Guinea and how to treat them. You would need to be able to come back for check-ups over 3 weeks.
Maférinya, ForécariahAges 2 months+ - NCT06127641Recruiting
Rehabilitation for lung disease after tuberculosis
This trial tests a pulmonary rehabilitation program for people who have ongoing lung problems after being treated for tuberculosis. It aims to help improve their breathing and physical function.
Rio de JaneiroAges 18 years+ - NCT05582512Recruiting
Study of long-term effects in children after COVID-19
This study looks at what long-term health effects children may have after getting COVID-19, and how those effects change over time. You may be asked to share health information and possibly complete a scan that can’t be done if certain metal is present.
Taipei, Chung Cheng DistrictAges Up to 18 years - NCT04745403RecruitingPhase 1
Trial of redirected HBV-targeting T cells for liver cancer
This Phase 1 study tests a lab-made immune cell treatment that targets hepatitis B (HBV)–related liver cancer. It may help by directing the body’s immune system to attack the cancer, while carefully checking safety.
SingaporeAges 21–75 - NCT05539014Recruiting
Study of newly diagnosed tuberculosis patients at Avicenne Hospital
This study follows people who are newly treated for tuberculosis, including lung and non-lung (extra-lung) cases. It may help doctors better understand tuberculosis and how patients respond after treatment starts.
BobignyAges 18–80 - NCT06135922RecruitingPhase 1
EBV-TCR-T cells for EBV-related HLH or infection
This trial tests a new immune cell therapy (EBV-TCR-T cells) for people with a severe immune reaction caused by the Epstein-Barr virus (EBV-HLH) or active EBV infection. The treatment uses special cells from a matched donor to help your body fight the virus.
Beijing, Beijing MunicipalityAges 1–60 - NCT06145841Recruiting
Gene test to guide infection treatment in AIDS
This study is for people with HIV/AIDS who develop severe pneumonia or septic shock. It uses a special genetic test (metagenomic next-generation sequencing) to find the exact germ causing the infection so doctors can choose the right antibiotic.
Guangzhou, GuangdongAges 18–65 - NCT06137196Recruiting
Lung function risks after severe pneumonia in AIDS patients
This study looks at why some people with AIDS who recover from severe pneumonia later have trouble breathing. Researchers want to find risk factors so they can help prevent lung damage.
Guangzhou, GuangdongAges 18–65 - NCT02936232Recruiting

Study sample collection for sepsis and after cardiac arrest
This trial collects and stores small samples from people in the ICU who are either being treated for sepsis or who have survived a non-traumatic cardiac arrest. It may help researchers better understand how the body changes after severe infection or after revival, which could improve future care.
SeoulAges 16 years+ - NCT06145828Recruiting
