Recruiting studies
- NCT04712539RecruitingPhase 2
Baloxavir and oseltamivir for severe flu in immune-compromised people
This trial tests whether two flu medicines—baloxavir and oseltamivir—work better to treat influenza in people with weakened immune systems (like transplant or blood cancer patients). It may help reduce severe complications, especially when flu affects the lungs or is at high risk to do so.
Houston, TexasAges 12 years+ - NCT04728516RecruitingPhase 4
Eradication treatment versus acid pills to prevent GI bleeding
This trial compares a “dual eradication therapy” (to get rid of H. pylori in the stomach) versus usual acid-reducing pills (PPIs) to lower the risk of gastrointestinal bleeding in people with recent heart artery disease treated with a stent. It may help by reducing stomach infection-related bleeding while you continue needed heart medicines.
Bozhou, AnhuiAges 18 years+ - NCT04743609Recruiting
Studying RSV illness impact in babies with ear or lung symptoms
This study looks at how RSV (a common virus that can affect breathing) leads to illness in young children who come to the doctor with ear infections and/or breathing symptoms. It may help doctors better understand the “burden” RSV causes in both home/outpatient and hospital settings.
CréteilAges 1 day–2 years - NCT04759001RecruitingPhase 1/Phase 2
Fecal treatment to clear gut bacteria resistant to antibiotics
This study tests a stool-based treatment (fecal microbiota treatment) to help remove “carbapenem-resistant” bacteria living in the gut. If you carry these bacteria without being sick, the goal is to reduce or stop that colonization.
RomeAges 18–90 - NCT04760574Recruiting
HIV status and low testosterone in men
This study looks at whether low testosterone (often called male hypogonadism) is linked to having HIV. It compares HIV-positive men with HIV-negative men to better understand what contributes to hormone problems and how common they are.
TaipeiAges 20 years+ - NCT04767945Recruiting
Cirrhosis patient hospital registry
This study keeps a record of people who have liver cirrhosis and were admitted to the hospital after a worsening event. It may help doctors better understand what leads to hospital stays and improve future care.
Banská BystricaAges 19 years+ - NCT04775134Recruiting
Checking leftover COVID virus after recovery
This study looks for whether small amounts of the COVID virus are still present in the lungs after infection. It may help doctors understand how long the virus can remain and inform future care, using tissue removed during a medically needed lung procedure.
LeuvenAges 18 years+ - NCT04790240RecruitingPhase 1/Phase 2
Herbal treatment aimed to reduce COVID-19 inflammation
This early-stage trial studies whether certain medical herbs can lower inflammation in people with recent COVID-19 and help the immune system better fight the virus. You may be able to join whether or not you take standard COVID medicines, but you would need to complete the herb plan and provide specific lab and scan results.
Rockville, MarylandAges Any age - NCT04791579RecruitingPhase 2
Preventing UTIs after Botox for neurogenic bladder
This study tests whether taking an antibiotic (ciprofloxacin) around the time of bladder Botox can prevent urinary tract infections (UTIs) in people whose bladder problems are caused by nerve conditions. It may help lower the chance of infection after treatment.
Edmonton, AlbertaAges 18–100 - NCT04807894RecruitingPhase 4
Vaginal testosterone to prevent repeat UTIs in postmenopausal women
This study tests whether putting testosterone in the vagina can help prevent future bladder infections (UTIs) compared with a dummy treatment. It’s for older postmenopausal women who keep getting UTIs, especially those who can’t or don’t want to use vaginal estrogen.
Brooklyn, New YorkAges 60–90 - NCT04813055Recruiting
Registry study for ultrasound during therapeutic endoscopy
This study keeps a careful record (registry) of patients who need ultrasound-guided therapeutic endoscopy. It aims to learn how well and safely this ultrasound technique works during real-life procedures.
MilanAges 18 years+ - NCT04815096RecruitingPhase 2
PET scan study of immune activity after COVID-19
This Phase 2 study uses a special PET scan to look at how active your immune system is after a recent COVID-19 infection. The goal is to understand what the immune response looks like and whether this imaging approach could help guide care.
San Francisco, CaliforniaAges 18 years+ - NCT04843111Recruiting
Registry study for pregnancy exposure to MenQuadfi vaccine
This is an observational registry that collects information about pregnant people and their babies when MenQuadfi® (a meningitis vaccine) was given during pregnancy or shortly before pregnancy. It helps researchers understand what happens to women and offspring after this vaccine exposure.
Swiftwater, PennsylvaniaAges Any age - NCT04855773Recruiting
Mobile text-message support to help people stay on PrEP
This trial tests whether phone-based (iPhone/Android) text-message support can improve how consistently people use PrEP, an HIV prevention medicine. It may help you stay on track with refills and clinic visits, especially if you’re at higher risk of stopping PrEP.
San Francisco, CaliforniaAges 15 years+ - NCT04880200Recruiting
HIV testing at the clinic with help getting care
This study tests point-of-care lab tests that can find HIV-related virus levels quickly, and adds support to help people stay on treatment and connect to prevention services. If you are already HIV-positive and coming in for same-day lab testing, you may be able to get extra help with follow-through.
Seattle, WashingtonAges 18 years+ - NCT04883255RecruitingEarly Phase 1
Study cannabis effects on brain function in adults with HIV
This early-phase study looks at how cannabis (and the body’s cannabinoid system) may affect thinking and brain-related measures in people with HIV. You may be asked to avoid cannabis and complete several brain and health assessments to see how these factors relate.
San Diego, CaliforniaAges 18–65 - NCT04901351Recruiting
Genetic testing for persistent high-risk HPV after treatment
This study uses a detailed DNA test to look for high-risk HPV in people with long-lasting (chronic) infection after treatment or with return of abnormal cells. It may help improve how clinicians monitor high-risk HPV and decide next steps.
ToulouseAges 18 years+ - NCT04921943RecruitingPhase 4
Hypertonic saline to treat MAC lung infection
This trial tests whether inhaled hypertonic saline can improve symptoms and lung health in people with a specific lung infection called MAC. It targets adults with confirmed MAC infection and bronchiectasis who are not already on certain MAC medications.
New York, New YorkAges 18 years+ - NCT07266831RecruitingPhase 2/Phase 3
Study of islatravir and ulonivirine for new HIV patients
This trial tests two new HIV medications, islatravir and ulonivirine, in people who have never taken HIV treatment before. It aims to see if this combination can safely control the virus.
Los Angeles, CaliforniaAges 18 years+ - NCT07525544RecruitingPhase 1
Safety Study of VH4770359 in Healthy Adults
This is an early-stage safety study testing a new investigational drug (VH4770359) in healthy volunteers. Researchers want to understand how the body processes the drug and ensure it is safe and well-tolerated.
Baltimore, MarylandAges 18–55 - NCT04937751Recruiting
Tests for infection and resistance in invasive fusarium
This trial looks at lab test results from samples taken to check for a serious (invasive) fungal infection caused by fusarium. It may help improve how doctors identify the infection and its drug resistance, which can guide better treatment.
Vandœuvre-lès-NancyAges Any age - NCT04949737Recruiting
Study stomach bacteria and stomach cancer in Martinique adults
This study looks at how common Helicobacter pylori (a common stomach germ) is in adults with stomach cancer in Martinique, and how it relates to stomach cancer. It mainly involves answering questionnaires and allowing study details to be collected to better understand risk and patterns.
Fort-de-FranceAges 18 years+ - NCT04952870Recruiting
Study breathing treatment and early immunity in newborns after COVID
This study looks at how newborns’ bodies are affected by COVID-19 around birth and whether a breathing support treatment (inhaled nitric oxide) changes outcomes. It also compares COVID-exposed babies and a similar group of babies without COVID who are not receiving the breathing treatment.
LilleAges Up to 3 months - NCT04955210Recruiting
