Recruiting studies
- NCT05398679RecruitingPhase 4
Oral antibiotics versus IV antibiotics after heart infection
This trial compares taking antibiotics by mouth versus receiving antibiotics through a vein (outpatient IV) for an infection of the heart valve. It’s designed to see whether the oral option can work as well and safely, especially after initial treatment and surgery if needed.
Alicante, AlicanteAges 18 years+ - NCT06841705RecruitingPhase 2
Early vedolizumab as first treatment for colitis from immunotherapy
This trial tests if giving vedolizumab early can help control severe diarrhea and colon inflammation caused by immunotherapy (a type of cancer treatment). It may offer a new option for people who develop these side effects.
Boston, MassachusettsAges 18 years+ - NCT06982105RecruitingPhase 4
Comparing two antibiotics for children with MRSA bone or head infections
This study compares two oral antibiotics, TMP-SMX and clindamycin, to see which works better for children with MRSA infections in bones, joints, or head/neck areas. It aims to find the best treatment after initial IV therapy.
Indianapolis, IndianaAges 2 months–18 years - NCT06709196RecruitingPhase 4
Targeted antibiotics to prevent infections after bladder removal
This trial tests if using a personalized antibiotic approach before surgery can reduce infections compared to the usual one-size-fits-all antibiotics. It focuses on people having their bladder removed (cystectomy) with a specific type of urinary diversion.
AalborgAges 18 years+ - NCT04851015RecruitingPhase 3
Low-dose TMP-SMX for Pneumocystis pneumonia (PCP)
This Phase 3 study tests whether low-dose trimethoprim-sulfamethoxazole (also called TMP-SMX) can treat Pneumocystis pneumonia (PCP) in people with weakened immune systems. It may help improve treatment while reducing side effects compared with standard dosing.
Montreal, QuebecAges 18–100 - NCT07451171RecruitingPhase 2
Comparing antibiotics for gut bacteria in children
This study compares three different antibiotics to treat small intestine bacterial overgrowth (an overgrowth of bacteria in the gut) in children in Bangladesh. It aims to find which antibiotic works best.
DhakaAges 1–2 - NCT03178149RecruitingPhase 1
Study of a new eye treatment for dry macular degeneration
This Phase 1 trial tests the safety and side effects of ASP7317 in older adults whose central vision is worsening from dry age-related macular degeneration (geographic atrophy). If you qualify, you would receive treatment in the study eye and be closely monitored for about a year.
Phoenix, ArizonaAges 50 years+ - NCT05302531RecruitingPhase 1
Testing high-absorption antibiotics for short-bowel syndrome
This early (Phase 1) study tests how well certain antibiotics get absorbed in the body when you have short-bowel syndrome. It may help doctors choose antibiotics that work better through the mouth for people with this digestion problem.
Vandœuvre-lès-Nancy, LorraineAges 18 years+ - NCT05678621RecruitingPhase 2/Phase 3
Testing stopping or extending immune treatment to prevent infections
This trial studies whether people with certain blood cancers can safely stop their immune support medicine (immunoglobulin, also called Ig) or whether they should continue. It also tests antibiotic prevention strategies to reduce the risk of serious infections.
Garran, Australian Capital TerritoryAges 18 years+ - NCT06336824RecruitingPhase 3
Switching from IV to oral antibiotics for staph bloodstream infection
This trial tests whether switching from IV antibiotics to oral antibiotics after 3–7 days is safe and effective for people with uncomplicated Staphylococcus aureus bloodstream infections. It may help you avoid a longer hospital stay and reduce IV-related complications.
Johor Bahru, JohorAges 18 years+ - NCT07202052RecruitingPhase 2/Phase 3
Antibiotics or immunoglobulin for infections in blood cancer
This trial compares two treatments—antibiotics or immunoglobulin (a blood product with infection-fighting antibodies)—to see which better prevents infections in people with certain blood cancers like CLL, multiple myeloma, or non-Hodgkin's lymphoma.
Adelaide, South AustraliaAges 18 years+ - NCT07202078RecruitingPhase 2/Phase 3
Starting immunoglobulin for infection prevention in hematology
This trial tests whether giving immunoglobulin to adults with low antibody levels can prevent infections. It aims to compare immunoglobulin with antibiotic therapy or no added treatment for people with blood conditions.
Adelaide, South AustraliaAges 18 years+ - NCT07202091RecruitingPhase 2/Phase 3
Stopping or extending immunoglobulin therapy to prevent infections
This trial tests whether it is safe to stop or extend immunoglobulin (Ig) therapy for people with low antibody levels, or if switching to preventive antibiotics works just as well to prevent infections.
Adelaide, South AustraliaAges 18 years+
