Testing the safety of multiple doses of BWC0977 in healthy people
This study tests an experimental antibiotic called BWC0977 to see if it is safe and well-tolerated when given as single and multiple doses. It is for healthy volunteers to understand how the drug behaves in the body before moving to patient trials.
Melbourne, VictoriaAges 18–55 - NCT07024641RecruitingPhase 1
Safety study of GIGA-2339 for chronic Hepatitis B
This study tests an experimental antibody (GIGA-2339) given as an infusion to people with chronic Hepatitis B. It aims to see if the drug is safe and how the body processes it, possibly helping to control the virus.
Chandler, ArizonaAges 18 years+ - NCT06995157Recruiting
HPV infections and vaccine attitudes in Slovenian women
This observational study looks at HPV infections and women's views about the HPV vaccine in Slovenia. It aims to understand the characteristics of HPV infections and attitudes toward vaccination after the vaccine became available.
Ljubljana, Municipality of DomžaleAges Up to 35 years - NCT07030920RecruitingPhase 2
Reducing inflammation in people living with HIV
This trial tests if a drug can lower inflammation in people with HIV who are on effective treatment. It may help reduce the risk of heart disease and other problems related to chronic inflammation.

Using smartwatch data to find early signs of infection in kids with cancer
This trial uses an Apple Watch and a smartphone app to track health data and detect early signs of infection in children and teens getting cancer treatment. The goal is to catch problems early so they can be treated quickly.
Parkville, VictoriaAges 5–18 - NCT07029958RecruitingPhase 4
Transplant protocol for EBV-related T/NK lymphoproliferative disease
This trial tests a stronger transplant conditioning regimen to treat a rare immune disorder caused by the Epstein-Barr virus. It aims to improve outcomes and reduce a complication called graft-versus-host disease, where donor cells attack the patient's body.
BeijingAges birth–18 years - NCT07030075Recruiting
