Eye and blood-vessel function study after COVID-19
This study measures how well the nerves in your retina and the tiny blood vessels in your eye “couple” (work together) after COVID-19. It may help researchers understand eye-related effects of COVID-19 and long COVID, and how these processes change over time.
Vienna, State of ViennaAges 18 years+ - NCT05652088Recruiting
Study gut immune tissue in HIV cure efforts
This study looks at how immune tissue in the gut may be involved in curing HIV. You may be asked to have two colonoscopies while on an HIV “cure-related” treatment, so researchers can collect tissue samples to understand what’s happening in your body.
New York, New YorkAges 18–75 - NCT05652374RecruitingPhase 4
Gag therapy for repeat bladder infections, compared to standard antibiotics
This trial tests a therapy (called GAG therapy) to prevent repeat urinary tract infections (UTIs) in adult women. It compares how similar the results are to a well-known antibiotic standard (nitrofurantoin) to see if it works reliably.
Nijmegen, GelderlandAges 18 years+ - NCT05654467RecruitingPhase 2
Oral polio vaccine study for young children in Panama
This trial tests a new oral polio vaccine in children and babies in Panama. The goal is to see if it is safe and helps the body build protection against polio.
Panama CityAges 1 day–4 years - NCT05655091RecruitingPhase 2
Personalized IV antibiotics for serious Staph aureus infections
This Phase 2 study tests whether continuous IV antibiotics plus “drug level monitoring” (TDM) works better than the usual treatment for complicated Staph aureus infections. It may help ensure the antibiotic dose stays in an effective range while you’re being treated.
BaselAges 18 years+ - NCT05655702Recruiting
Drug use and infections study for tuberculosis control in Vietnam
This study looks at how injecting drug use is linked with infections, including tuberculosis, and aims to improve TB control. You may be asked to share information and provide tests related to recent drug use and injection sites.
HaiphongAges 18 years+ - NCT05655910Recruiting
Nutrition support program for people with LVADs in the hospital
This trial tests whether an enhanced nutrition plan can improve care for adults who already have an LVAD (a heart pumping device). It’s designed for hospitalized patients and looks at who can safely eat by mouth while avoiding high-risk situations.
New York, New YorkAges 18 years+ - NCT05656365Recruiting
Study of genes and immunity in PFAPA and other tonsil problems
This study looks at genetic markers and immune system patterns in people with PFAPA (periodic fevers with mouth sores and throat/neck gland symptoms) or similar tonsil problems. It may help researchers understand why these conditions happen and how they might be better diagnosed or treated.
Washington D.C., District of ColumbiaAges 1 month–99 years - NCT05659589Recruiting
Using a kidney toxin level to predict heart effects in AKI
This study looks at whether measuring indoxyl sulfate, a substance that can build up when kidneys are injured, can help predict how blood vessels and the heart are affected during acute kidney injury (AKI). It may help doctors understand who is at higher risk of heart-related problems while AKI is happening.
AmiensAges 18 years+ - NCT05660148Recruiting
HIV study on resentment, forgiveness, and quality of life
This study looks at how feelings like resentment and the ability to forgive relate to quality of life in people living with HIV. You may be asked to participate in questionnaires and/or follow-up that can be done by phone or video.
AmiensAges 18 years+ - NCT05660733Recruiting
Study of infections of the aorta and large arteries
This trial studies how to care for infections that involve the aorta or other large blood vessels. If you have signs and test results that fit this diagnosis, you may be invited to help researchers better understand the condition and treatments.
Vandœuvre-lès-Nancy, LorraineAges 18 years+ - NCT05661786Recruiting
Study outcomes for hepatitis B with “indeterminate” disease phase
This trial studies what happens to people with hepatitis B who have hepatitis B surface antigen for more than 6 months, are “HBeAg-negative,” and have certain blood and liver-scarring levels despite normal or near-normal liver inflammation. It may help doctors understand the best care for this specific group before clear treatment phases.
Changzhou, JiangsuAges 18 years+ - NCT05663008Recruiting
Testing nerve-to-muscle signal changes to diagnose movement diseases
This study measures how nerves communicate with muscles, using recordings and gels. It aims to spot early, personalized signs of conditions like ALS and related diseases, and to improve diagnosis.
Dublin, LeinsterAges 18 years+ - NCT05663502Recruiting
Donate blood and tissue samples for HIV-related cancer research
This study collects blood and tissue samples to help researchers learn more about cancers related to HIV/AIDS. You may be able to join if you’re 18+ and have HIV and a cancer diagnosis, or (if HIV-negative) a certain cancer that is closely linked to AIDS-related cancers.
