DhakaAges 1 year+ - NCT07683117Recruiting
PEP/PrEP through pharmacist prescribing (PEPPI)
This study looks at how well pharmacists can provide PEP and PrEP (HIV prevention pills) using a special software called PEPPI. It aims to make it easier and faster for people to get these medicines.
Del Mar, CaliforniaAges 18 years+ - NCT07681583Recruiting
Fungal pneumonia risk score study
This study is developing a tool to better predict fungal pneumonia in people who come to the emergency department or hospital with pneumonia. By analyzing samples from your lungs and other data, researchers hope to improve diagnosis and treatment decisions.
FlorenceAges 18–90 - NCT07684300Recruiting
Testing a faster infection test to improve antibiotic use
This trial looks at whether a rapid molecular test can help doctors choose the right antibiotics faster for hospitalized patients. It aims to improve how antibiotics are used and reduce unnecessary side effects.
Elche, AlicanteAges 18 years+ - NCT07682766Recruiting
Biomarkers of inflammation and infection in critical care
This study looks at markers of inflammation, infection, and immunity in patients who are in the critical care area. It aims to find early signs of how severe the illness might become, how well treatments work, and if infections will develop.
TorinoAges 18 years+ - NCT07686913Recruiting
Steri-Strips vs standard closure for C-section incisions
This study compares using Steri-Strips (a special type of tape) to close the C-section incision versus the standard method. The goal is to see which way helps the wound heal better.
Moreno Valley, CaliforniaAges 18 years+ - NCT07684820RecruitingPhase 2
A study of ExPD-101 for COPD with chronic bronchitis and frequent flare-ups
This study tests an experimental drug (ExPD-101) given daily as a pill for 52 weeks for people with COPD who have chronic bronchitis and frequent flare-ups. It compares the drug to a placebo (inactive pill) to see if it reduces flare-ups and improves symptoms.
Phoenix, ArizonaAges 40–85 - NCT07682961RecruitingPhase 3
Study of new HIV injection vs. standard injectables
This phase 3 trial tests a new long-acting, injectable two-drug combination (lenacapavir + teropavimab + zinlirvimab) vs. another injectable combo (cabotegravir + rilpivirine) for people whose HIV is already well-controlled on daily oral meds. It aims to see if the new combo can keep the virus under control with fewer injections.
San Francisco, CaliforniaAges 18 years+ - NCT07685457Recruiting
Virus-specific T cells for stubborn viral infections after transplant
This trial tests whether specially trained immune cells (virus-specific T cells) can safely treat stubborn viral infections after a stem cell transplant. It focuses on children and young adults who have not responded to standard antiviral treatments.
SeoulAges 1–25 - NCT07688369RecruitingPhase 1
Testing a new polio vaccine in healthy adults
This trial tests a new recombinant polio vaccine (rPV) to see if it is safe and works as well as the current IPOL vaccine. It is for healthy adults who have not had polio or a polio vaccine recently.
East Melbourne, VictoriaAges 18–60 - NCT07683000RecruitingPhase 3
Study of three HIV drugs for adults with controlled HIV
This trial tests a new combination of three medications, lenacapavir, teropavimab, and zinlirvimab, for people with HIV who currently have undetectable virus levels on a stable oral treatment. The goal is to see if these drugs can keep the virus suppressed, possibly allowing a simpler treatment plan.
