HIV vaccine with treatment break to boost immune response
This Phase 1 trial tests two new HIV vaccines (DV700P-RNA and DV701B1.1-RNA) combined with a monitored break from HIV medications in people with well-controlled HIV. The goal is to see if this approach safely strengthens the immune system's ability to fight HIV.
Birmingham, AlabamaAges 18–60 - NCT07572396RecruitingPhase 2
HPV treatment with vaginal suppositories for mild cervical changes
This study tests a new vaginal medication (Dysplasix) to treat mild cervical cell changes caused by high-risk HPV. The goal is to see if this treatment can help your body clear the virus and prevent these changes from getting worse.
Shatin, New TerritoriesAges 18–65 - NCT07576868RecruitingPhase 2/Phase 3
Study of CP-COV03 Treatment for Dengue and Dengue-like Illness
This trial tests whether a new medicine called CP-COV03 can help people recover faster from dengue fever or dengue-like illness. You would receive either the study medicine or a placebo (inactive pill) and be monitored closely to see if symptoms improve.
HanoiAges 18 years+ - NCT07573462RecruitingPhase 3
Safety study of a new pneumococcal vaccine for infants
This study tests whether a new pneumococcal vaccine (which protects against a serious bacterial infection) is safe in healthy 2-month-old infants. Researchers will watch for side effects and help protect future babies from pneumococcal disease.
Estero, FloridaAges 1 month–3 months - NCT07569900Recruiting
Testing a new gonorrhea test for women
This study evaluates a new rapid test for gonorrhea designed for women. You'll provide vaginal swab samples and complete a brief counseling session to help researchers understand how well the test works and whether patients can use it correctly.
Johannesburg, GautengAges 16 years+ - NCT07575009RecruitingPhase 3
Home-based continuous antibiotic infusion for children
This study tests whether children can safely receive antibiotics continuously through a pump at home instead of in the hospital. The goal is to help children recover while staying with their family and avoiding prolonged hospital stays.
TampereAges Up to 16 years - NCT07577232Recruiting
Ultrasound imaging for diagnosing throat abscesses
This trial tests whether using ultrasound (sound wave imaging) through the mouth helps doctors better diagnose a throat abscess—a pocket of infection near the tonsil. The goal is to see if this imaging method improves diagnosis accuracy and treatment decisions.
CopenhagenAges 18 years+ - NCT07569653RecruitingPhase 4
CMV Prevention After Stem Cell Transplant Using Blood Tests
This trial tests whether doctors can safely stop a CMV prevention medication (letermovir) earlier by using blood tests to check your immune system's strength. CMV is a virus that can become dangerous after stem cell transplant, and this study aims to prevent it while minimizing unnecessary medicine.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07575919RecruitingPhase 1/Phase 2
CAR-T Cell Therapy for Standard-Risk B-ALL After Chemotherapy
This trial tests a new type of immunotherapy called CAR-T cells to help prevent relapse in adults with B-cell acute lymphoblastic leukemia (a blood cancer) who have responded well to standard chemotherapy. The treatment is designed as a consolidation therapy to strengthen remission after initial chemotherapy.
