Phase 2 study of a Rift Valley fever vaccine for safety
This study tests how safe a Rift Valley fever (RVF) vaccine is and how strongly it triggers the body’s immune response. You may be eligible if you are at risk of RVF exposure and your blood test shows you don’t already have strong protection.

Test drops to thin lung mucus in severe COVID-19
This Phase 2 trial tests rhDNase (a medication similar to Pulmozyme) to improve outcomes and reduce the risk of death in people with severe COVID-19 causing breathing failure. It’s meant for adults who need high-flow oxygen or a breathing machine.
Mobile, AlabamaAges 18 years+ - NCT03869619Recruiting
Real-life data study for adults with recent lymphoma
This study collects “real-world” health information about adults whose lymphoma was diagnosed within the last 6 months. It aims to better understand lymphoma types and how patients do over time, using data from everyday care rather than testing a new drug.
ArrasAges 18 years+ - NCT04910802RecruitingPhase 4
HPV vaccine with routine HPV screening for ages 22–26
This study looks at giving the HPV vaccine (Gardasil 9) to women while they go through Sweden’s routine HPV screening. It helps researchers understand how vaccine use alongside screening affects HPV infection and cervical cancer prevention.
StockholmAges 22–27 - NCT04746209RecruitingPhase 2
Blinatumomab after transplant for high-risk B-ALL patients
This trial tests blinatumomab, an immune therapy, in young people with B-cell acute lymphoblastic leukemia (B-ALL) after their transplant or when they are getting ready for transplant. The goal is to lower the chance of the leukemia coming back by targeting remaining leukemia cells.
Milwaukee, WisconsinAges Up to 25 years - NCT04335773Recruiting
Study of COVID-19 in hospitalized children
This study looks at children (ages 0 to 18) who are in the hospital with suspected COVID-19. It aims to understand what factors affect outcomes and how the immune system responds.
LørenskogAges Up to 18 years - NCT04558450Recruiting
Study how COVID-19 affects blood vessel stiffness and aging
This study looks at how having COVID-19 may affect your blood vessels over the following months. It may help doctors understand long-term “vascular aging” and who is most at risk, based on how sick you were during your COVID illness.
NancyAges 18 years+ - NCT04320732Recruiting
Study COVID-19 spread at home and work
This study looks at what factors make COVID-19 spread more easily in the community and workplace. It may help researchers understand how to reduce transmission in everyday settings.
OsloAges 18 years+ - NCT05255978Recruiting
Follow-up study for hepatitis B with fatty liver
This observational study looks at people with chronic hepatitis B who also have fatty liver (non-alcoholic fatty liver disease). It follows how their liver health changes over time and may help doctors understand outcomes and risk factors.
Wuhan, HubeiAges 18 years+ - NCT05326061Recruiting
Study for people at high risk of getting HIV
This registry study looks at people who are HIV-negative but at high risk of getting HIV, to better understand risk and care needs. If you qualify, you may be asked to share health and behavior information to help guide future prevention efforts.
ViennaAges 18–100 - NCT05195450Recruiting
Tenofovir to stop liver disease in mild hepatitis B
This trial tests tenofovir alafenamide (a hepatitis B antiviral medicine) to see if it can prevent liver disease from getting worse in people with chronic hepatitis B who currently have stable (normal) liver blood tests and low virus levels. It may help lower the chance of developing serious liver complications over time.
New Delhi, National Capital Territory of DelhiAges 18–70 - NCT04446676Recruiting
Stabilization method after staged knee revision for infection risk
This study compares two ways of stabilizing a knee implant after a two-step (staged) knee revision to see which better prevents reinfection. It may help people trying to avoid another infection after treatment of a previously infected knee implant.
Otwock, Masovian VoivodeshipAges 18–90 - NCT02803242Recruiting
Patient research network for people with lung symptoms
This trial enrolls adults to help build a patient-powered research network for chronic lung disease. If you join, you’ll likely be asked to complete surveys or provide information to help researchers learn how symptoms and health outcomes change over time.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05284318Recruiting
Antibiotic plans and outcomes after two-stage joint revision
This study looks at how antibiotic treatment (especially the course length and approach) relates to infection control and results after a two-step surgery for joint infections. If you’ve had a spacer placed, finished at least 6 weeks of antibiotics, and then had the second surgery, the research team may want to follow your outcomes over time.
Fuzhou, FujianAges 18 years+ - NCT05286931Recruiting
Test for gonorrhea using a urine swab lab assay
This study checks whether a specific lab test (the “gyrA assay”) can detect gonorrhea in people who do not have symptoms. It may help clinicians find gonorrhea more quickly and with the right treatment when symptoms aren’t present.
Seattle, WashingtonAges 18 years+ - NCT02801253Recruiting
Study of infections around hip, knee, or shoulder implants
This study follows people who have an infection around a hip, knee, or shoulder implant (prosthesis). It uses standard infection tests (like cultures and blood tests) to confirm the diagnosis and better understand this problem after surgery.

Registry for adults with bronchiectasis and non-tuberculosis lung bacteria
This study is a registry that collects health information from adults who have bronchiectasis caused by non-tuberculosis mycobacteria (NTM). It helps researchers better understand this condition and improve future treatments.
