Home monitoring study for lasting breathing symptoms after COVID
This study looks at people with lingering post-COVID symptoms, especially breathing and lung-related findings, using home monitoring and medical tests. It may help researchers understand what’s driving ongoing symptoms and identify patterns that could guide better care.

This study tests whether a telehealth program can reduce harm and lower HIV risk by helping with safer syringe use. It may help if you have recent syringe exchange use and are not currently on HIV prevention pills.
Miami, FloridaAges 18 years+ - NCT05897879Recruiting
Study how pertussis germs and immune response affect severity
This study looks at children with suspected pertussis (who need a PCR test) and compares how the bacteria and the immune response relate to how sick they become. It may help doctors understand why some children have worse symptoms and guide future care.
BordeauxAges Up to 15 years - NCT05898529Recruiting
Testing COVID status in children having surgery
This study looks at how COVID-19 infection is handled in children (ages 2–17) who are scheduled for surgery. The goal is to compare testing/safety approaches and see how they may protect pediatric surgical patients.
Surrey, British ColumbiaAges 2–17 - NCT05899140RecruitingPhase 4
Clindamycin added to treat certain skin infections
This trial tests whether adding clindamycin helps treat skin and soft-tissue infections caused by Staphylococcus aureus. You may be eligible if your infection was diagnosed recently and a sample was collected soon after hospital admission.
MasokoriAges 18 years+ - NCT05903352RecruitingPhase 3
Personalized antibiotic duration for hospital pneumonia patients
This trial compares how long antibiotics should be given to people hospitalized with moderately severe community-acquired pneumonia. It uses your early improvement to see which antibiotic duration works best and safely.
GarchesAges 18 years+ - NCT05903742Recruiting
Standard care for hepatitis delta in the Netherlands
This trial focuses on improving and standardizing how hepatitis delta is cared for in the Netherlands. To take part, you must have confirmed active hepatitis delta and be an adult.
RotterdamAges 18 years+ - NCT05905640Recruiting
PrEP clinic support study for Kenya health workers and policy makers
This trial tests a “one-stop” support pathway meant to make it easier for PrEP clinics in Kenya to deliver PrEP care. It involves interviews with people using PrEP services and with healthcare and policy leaders who help run or guide PrEP delivery.
KisumuAges 15 years+ - NCT05906030Recruiting
Ultrasound to study diaphragm function around surgery
This trial uses ultrasound (a non-painful scanning method) to measure how well the diaphragm works around the time of surgery. It aims to learn whether diaphragm changes during surgery relate to breathing problems, especially in people undergoing abdominal, pelvic, or vascular operations.
Stockholm, Stockholm CountyAges 18–100 - NCT05906472Recruiting
Feeding through a tube after tracheostomy in the ICU
This study tests a specific way of continuing tube feeding for people who need a tracheostomy after being on a breathing tube in the ICU. The goal is to see if this feeding approach is safe and beneficial for recovery.
Danbury, ConnecticutAges 18 years+ - NCT05907759RecruitingPhase 2
Daratumumab treatment for certain relapsed blood cancers
This Phase 2 trial studies daratumumab (an antibody medicine) for adults whose rare lymph node/immune-related cancers have come back or did not respond to treatment. It may help shrink disease and improve symptoms, including for people living with HIV when their virus is well controlled.
Bethesda, MarylandAges 18–120 - NCT05908682Recruiting
Study of ibrexafungerp safety during pregnancy
This study looks at what happens when ibrexafungerp is taken during pregnancy, including outcomes for the baby. You may join if you were exposed to this medicine during pregnancy (or very close to conception) and you agree to share information and complete study follow-up.
New Delhi, Vasant ViharAges birth+ - NCT05910580Recruiting
Screening and support for alcohol and substance risk in adults
This study aims to improve care access and outcomes for adults who screen positive for risky alcohol or drug use. If you qualify, you may be offered ways to connect to support during your reproductive years.
Boston, MassachusettsAges 18 years+ - NCT05911750Recruiting
HPV study in men with Crohn’s or ulcerative colitis
This study looks at how common human papillomavirus (HPV) is in men with Crohn’s disease or ulcerative colitis and what it may mean for health. You would answer questions and provide biology samples so researchers can understand the link, if any, between HPV and bowel disease.
BarcelonaAges 18–79 - NCT05911503RecruitingEarly Phase 1
High-dose ganciclovir eye drops for CMV eye infection
This early-phase study tests high-concentration ganciclovir eye drops to treat cytomegalovirus (CMV) retinitis, a serious eye infection. It may help people who are hard to treat with regular (systemic) antiviral medicine or who face higher risks with an injection directly into the eye.
Tianjin, Tianjin MunicipalityAges 2–80 - NCT05911828RecruitingPhase 1
Oral malaria pill study in adults without symptoms
This Phase 1 study tests how safe a combination oral medicine (ZY19489 with ferroquine) is in adults who carry malaria in their blood but have no symptoms. It also studies how the body absorbs and processes the medicines.
LambarénéAges 18–55 - NCT05912413Recruiting
Predicting how people recover from sepsis in the ICU
This pilot study looks at whether doctors can sort ICU patients with sepsis into recovery “types” and predict how well they will recover. It may help future care plans for people after sepsis by identifying who needs what kinds of support.
Birmingham, AlabamaAges 18–80 - NCT05914649Recruiting
Testing long COVID and POTS brain fog symptoms
This study tests how different long-COVID and POTS-related symptoms—especially “brain fog”—show up and improve. It may help researchers better measure symptoms so future treatments can be targeted more effectively.
Calgary, AlbertaAges 18–60 - NCT05914779Recruiting
Early antibiotics after out-of-hospital cardiac arrest
This study looks at whether starting antibiotics soon after an out-of-hospital cardiac arrest helps patients who are unlikely to have an infection. Antibiotics may prevent or treat infection-related complications, but only if certain infection and health conditions are met.
Doha, Baladiyat ad DawhahAges 18 years+ - NCT05916638Recruiting
Testing a breathing pattern in people with sarcoidosis and TB
This trial looks at a specific “MoMa signature” related to breathing or lung signals in adults who have been diagnosed with both sarcoidosis and tuberculosis. It may help researchers understand how these conditions affect the body and improve how patients are monitored.
ParisAges 18 years+ - NCT05917210Recruiting
Peer support for TB and HIV treatment in Uganda
This trial tests a peer-led education and counseling program to help people with TB and HIV stick with their treatment. It may help improve understanding, motivation, and day-to-day adherence to medications.

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+ - NCT05922306RecruitingEarly Phase 1
Testing continuous vs pulsed treatment for chronic hepatitis B
