Metformin add-on for newly diagnosed leprosy treatment
This Phase 2 trial tests whether adding metformin to standard leprosy treatment (multidrug therapy, or MDT) helps people with multibacillary leprosy recover better and remain tolerable over 48 weeks. Participants also get monitored closely for side effects and safety issues.
Tangerang, BantenAges 18–65 - NCT06706362RecruitingPhase 4
Antibiotics before Bulkamid for bladder leakage
This study tests whether giving a single dose of antibiotics before a Bulkamid procedure (a gel injection for bladder leakage) helps prevent infections. It is for people with stress urinary incontinence (leakage with coughing or sneezing) who are already planning to have this treatment.
Columbus, OhioAges 18–50 - NCT06712641RecruitingPhase 4
Testing aminoglycoside antibiotics for early sepsis
This trial tests a type of antibiotic called aminoglycosides to treat early sepsis (a serious infection). It is for adults in the hospital who are sick enough to need strong antibiotics but not in the worst stage of the illness.
Bergen, BergenAges 18 years+ - NCT06710418Recruiting
Comparing two red blood cell transfusion thresholds for people with high-grade myeloid neoplasms, AML or B-ALL
This study compares two different strategies for when to give red blood cell transfusions to people receiving intensive chemotherapy or stem cell transplant for high-grade myeloid neoplasms, AML or B-ALL. The goal is to see which approach better improves quality of life and daily function.
Seattle, WashingtonAges 18 years+ - NCT06710080RecruitingPhase 3
Testing a medicine to reduce inflammation in pneumonia patients
This trial tests if a medicine called icosapent ethyl can reduce inflammation in blood vessels for adults hospitalized with pneumonia. It aims to see if this treatment can help prevent complications.
Ottawa, OntarioAges 18 years+ - NCT06706986Enrolling by invitation
Global registry for people with HIV who failed newer integrase inhibitors
This trial is a registry for people with HIV whose virus is no longer fully controlled by certain newer medications (integrase inhibitors). It aims to collect data to better understand why these treatments stop working and how to improve future care.
UtrechtAges Any age - NCT06715306Recruiting
IV vs. Oral Antibiotics for Common Infections
This trial compares starting antibiotics through a vein (IV) to taking them by mouth for common infections like pneumonia, urinary tract infections, or skin infections (cellulitis). The goal is to see if oral antibiotics work just as well without the need for an IV line.
Aabenraa, Southern DenmarkAges 18 years+ - NCT06716450Recruiting
HIV and syphilis self-test study
This study tests a new self-test for HIV and syphilis that you can do yourself at a clinic or community site. It is for people who do not know if they have HIV or syphilis and have not tested positive before.
Victoria, British ColumbiaAges 18 years+ - NCT06709573RecruitingPhase 4
