- NCT05829629RecruitingPhase 1
Test of an HPV vaccine-like treatment for HPV16 in women
This Phase 1 study tests FluBHPVE6E7, a new treatment designed to help the immune system respond to HPV16. It mainly checks safety and the best dose, and may help your body clear or control HPV over time.

Remote preconditioning therapy for newly sick sepsis patients
This trial studies whether a “remote preconditioning” treatment given during early sepsis can help protect the kidneys and improve outcomes. It is for adults in the ICU very soon after sepsis begins.
MünsterAges 18 years+ - NCT05832307Recruiting
Testing whether inpatient flu shots improve vaccination rates
This trial looks at an organized plan to give flu vaccines during hospital stays. It may help more inpatients get protected against influenza before they leave the hospital.
Chicago, IllinoisAges 6 months–99 years - NCT05833217Recruiting
Study for persistent COVID symptoms with insulin resistance
This trial studies people who have ongoing effects after COVID (often called PASC) and may be related to weight and insulin resistance. It may help researchers find better ways to understand the condition and improve treatment.
Palo Alto, CaliforniaAges 18–80 - NCT05835102Recruiting
How nutrition measures may affect COVID-19 outcomes
This study looks at nutrition-related measurements to see how they may relate to how people with COVID-19 do over time. It may help doctors better predict who is at higher or lower risk based on nutrition status.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT05835206RecruitingPhase 2
Drug to reduce antibiotic-resistant gut bacteria
This Phase 2 study tests whether an investigational treatment can help clear or reduce antibiotic-resistant bacteria living in the gut. It may help prevent these germs from causing future infections by targeting specific resistant bacteria found on stool or rectal swabs.
Atlanta, GeorgiaAges 18 years+ - NCT05835479RecruitingPhase 2
Rezafungin to treat Pneumocystis pneumonia in adults with HIV
This Phase 2 trial tests rezafungin, an antifungal medicine, to treat Pneumocystis pneumonia (PCP) in adults living with HIV. It may help people recover faster or more effectively from this serious lung infection.
Cape TownAges 18 years+ - NCT05836272RecruitingPhase 4
Early norepinephrine for low blood pressure in sepsis
This trial tests whether starting norepinephrine early can improve outcomes for adults with sepsis who have low blood pressure. It may help stabilize circulation sooner and reduce complications from severe infection.
TunisAges 18 years+ - NCT05842382RecruitingPhase 2
High-dose IV vitamin C for severe pneumonia
This trial tests whether high-dose vitamin C given through an IV can improve outcomes in people with severe pneumonia. It may help your body fight infection and reduce complications, but it also has several safety checks.
Alor Star, KedahAges 18 years+ - NCT05842161Recruiting
Help quitting smoking for people with HIV and TB care
This study supports quitting smoking while you are receiving HIV and/or TB care. It aims to improve engagement in care and smoking cessation for people who smoke daily.
RondeboschAges 18 years+ - NCT05843786RecruitingPhase 3
Interferon gamma for ventilator pneumonia in ICU
This trial tests whether a medicine called interferon gamma can improve outcomes in adults with a first episode of pneumonia that develops after being on a ventilator in the ICU. It is designed for specific ICU timing, infection severity, and immune marker levels, and it compares treatment on top of standard care.
LimogesAges 18 years+ - NCT05846399RecruitingPhase 4
Test antibiotic prevention after a cat bite to the hand
This study tests whether taking a specific antibiotic right after a cat bite to the hand or forearm can help prevent an infection. You may be eligible if you arrive within 24 hours and don’t already have signs of infection.
Columbia, MissouriAges 18 years+ - NCT05846438Recruiting
Drain care check after breast implant surgery
This study looks at whether a specific way of caring for surgical drains can lower infection rates and improve quality of life after breast reconstruction with a tissue expander. You may be asked to follow the study’s drain-care steps during recovery.
Columbia, MissouriAges 18–100 - NCT05847036Recruiting
Study of urinary tract infection symptoms in family doctors
This study looks at how urinary tract infections show up in everyday primary care and what urine tests find. You might help doctors better recognize and manage these infections in real-world practice.
Saint-Maur-des-Fossés, Saint MaurAges 18 years+ - NCT05848570Recruiting
Digital program for reducing HIV risk in SGM youth
This trial tests a digital health program (available with limited in-person contact) to help SGM young people reduce their risk of HIV. You may be a good fit if you’re in the right age range and have had certain types of sex in the last 6 months.
Chicago, IllinoisAges 13–34 - NCT05848713RecruitingPhase 3
Blood-thinner treatment for complications of community pneumonia
This Phase 3 trial tests whether an anti-clot “blood thinner” can reduce complications from community-acquired pneumonia in hospitalized adults who need extra oxygen. It may help by lowering harmful clot-related effects during serious lung infection.
Chicago, IllinoisAges 18 years+ - NCT05849467RecruitingPhase 1
Testing how the brain absorbs anti–CD8 therapy in nervous system disease
This Phase 1 study tests a small drug (called an anti–CD8+ T cell minibody) to see how much reaches the brain. It may help researchers understand how to deliver similar treatments for multiple sclerosis, progressive multifocal leukoencephalopathy (PML), or other brain inflammation when the brain’s protective barrier is “open.”
Bethesda, MarylandAges 18–120 - NCT05849038RecruitingPhase 2
Treating inflammation to improve depression in HIV
This Phase 2 study looks at whether lowering inflammation can help improve depression symptoms in adults living with HIV. You may be able to join if your HIV is well controlled and you are currently experiencing major depression (or a certain type of bipolar depression).
Atlanta, GeorgiaAges 18–65 - NCT06075264RecruitingPhase 2
Artesunate ointment for high-grade vulvar lesions
This trial tests an artesunate ointment for women with high-grade vulvar lesions caused by HPV. It aims to see if the ointment can help the lesions heal or disappear without needing surgery.
Fort Myers, FloridaAges 18 years+ - NCT05851859Recruiting
Breathing training for long COVID symptoms

Saint-DenisAges 18 years+ - NCT05852158RecruitingPhase 4
Antibiotics to prevent infection after jaw surgery
This trial tests whether giving antibiotics can lower the chance of infection after orthognathic (jaw) surgery. It may help by preventing post-surgery infections, but participation depends on your health history and medication allergies.
Halifax, Nova ScotiaAges 16 years+ - NCT05853718RecruitingPhase 4
Tenofovir treatment for hepatitis B during pregnancy
This study tests tenofovir alafenamide (TAF) to lower hepatitis B in pregnant people and reduce the chance of passing it to the baby. You may be able to join if you’re pregnant with active hepatitis B and meet safety lab and pregnancy ultrasound requirements.
Hangzhou, ZhejiangAges 20–40 - NCT05854563Recruiting
