Study of viral infections in healthy and immune-compromised people
This trial studies how viruses affect the body, and how the immune system responds, in both healthy people and people with weakened immunity. It may include people who currently have a suspected or recent viral infection, close contacts, people around the time of a viral vaccine, and healthy adults used for comparison.

Centralized care for ovarian cancer: a study of outcomes
This study looks at whether having ovarian cancer care coordinated by a special team (Multidisciplinary Tumor Board) leads to better outcomes. It reviews records of patients treated between 2018 and 2023 to understand how centralization affects their health.

Testing gut bacteria's effect on brain function and inflammation
This trial looks at whether short-chain fatty acids (substances made by gut bacteria) can reduce inflammation and improve thinking skills (executive function). You'll receive an injection that causes mild, temporary inflammation (like a bad cold) and complete cognitive tasks.
LeuvenAges 18–45 - NCT06814496RecruitingPhase 1/Phase 2
Radiation and immunotherapy combo for DLL3-positive cancers
This trial combines radiation with an immunotherapy drug called tarlatamab to treat cancers that make a protein called DLL3. The goal is to see if this combination works better than either treatment alone for people with certain types of lung cancer and other tumors that have not responded to prior therapy.
Tucson, ArizonaAges 18–99 - NCT07715435Recruiting
Collecting samples to improve echinococcosis testing
This study collects tissue and blood samples from people having surgery for echinococcosis. The samples will help develop a better PCR test (a lab test that detects the parasite) so doctors can diagnose the infection more accurately.
Alessandria, Piemonte, ItalyAges 6 years+ - NCT07018076Recruiting
TB treatment study for people who just finished therapy
This study looks for people who have recently completed standard treatment for drug-sensitive TB. Researchers want to check if certain tests can predict long-term health outcomes after treatment.
KampalaAges 12 years+ - NCT06810739Recruiting

Defibrotide for severe COVID-19 in adults
This trial tests defibrotide to see if it improves outcomes in people hospitalized with severe COVID-19. You may be considered if you have confirmed infection, abnormal chest imaging, and meet specific severity and safety requirements.
Boston, MassachusettsAges 18–100 - NCT07543419Recruiting
Real-world Study of Secukinumab for Moderate to Severe Hidradenitis Suppurativa
This study tracks how secukinumab (a new medication) works for hidradenitis suppurativa—a painful skin condition with recurring boils and abscesses—in real-world patient care in Italy. Researchers want to understand treatment patterns and outcomes to help improve care for this condition.
Ancona, ANAges 18–100 - NCT07710118RecruitingPhase 3
Comparing two doses of ceftriaxone for gonorrhea in men
This trial is testing whether a lower dose (500 mg) of the antibiotic ceftriaxone works as well as the standard dose (1000 mg) for treating gonorrhea in men. If you have a gonorrhea infection in your throat, rectum, or genitals and are otherwise healthy, you may be able to join.

Study of NWRD09 for persistent HPV 16 infection in women
This trial tests an experimental treatment called NWRD09 for women who have had a persistent HPV 16 infection for at least 12 months. The goal is to see if it can clear the virus and prevent cervical changes.
BeijingAges 45–65 - NCT07711223RecruitingPhase 1/Phase 2
New HIV pill compared to standard treatment for untreated adults
This trial compares a new HIV medication (ACC017) to an existing one (dolutegravir) in adults who have HIV but have never taken HIV drugs before. The goal is to see if the new pill works as well and is safe.
BeijingAges 18 years+ - NCT07709520RecruitingPhase 2
Testing a new hepatitis B treatment in adults
This trial tests a new treatment (GST-HG131&141 tablets) versus a placebo for people with chronic hepatitis B. It aims to see if the treatment can better control the virus in those already on stable therapy.
BeijingAges 35–65 - NCT07711431Recruiting
Connection between gum disease and ongoing neck pain
This study looks at whether there is a link between gum (periodontal) disease and long-term neck pain without a clear cause. If you are between 30 and 55, have most of your own teeth, and don't take regular pain medicine, you may be able to help doctors understand this connection.
