Escherichia coli infection

Pfizer is testing several experimental vaccines designed to protect against E. coli bacteria. This early-stage study involves 310 healthy adults aged 18 to 64. The main goal is to check if the vaccines are safe and tolerable, not yet whether they work. Participants will receive t…

This study tests a new vaccine designed to prevent urinary tract infections (UTIs) caused by E. coli bacteria. Researchers will check safety and immune response in 448 adults aged 18-64, and then see if it works in women of the same age. Participants receive either the vaccine or…

This study tests whether giving children with a severe E. coli infection extra fluids through an IV can prevent kidney failure. About 1,040 children aged 9 months to 21 years will take part. The goal is to see if this simple approach reduces the need for dialysis or long-term kid…

This early-stage study tests whether a mixture of viruses (called phages) that specifically kill E. coli bacteria is safe for people with spinal cord injuries who have bacteria in their bladder. Thirty adults will receive the phage solution directly into the bladder twice daily f…

This study tests whether using early drug monitoring and a dose-adjustment calculator can help infants under 90 days old with sepsis reach target vancomycin levels more quickly. Currently, doctors must wait 24-48 hours to check drug levels, which can delay effective treatment. Th…

This study tests a new treatment called LBP-EC01, which uses specially designed viruses (bacteriophages) to attack drug-resistant E. coli bacteria that cause urinary tract infections (UTIs). About 318 adults with a history of UTIs and a current infection will receive either LBP-E…

This study is testing whether a powerful antibiotic called piperacillin/tazobactam can be given as a continuous shot under the skin instead of through an IV line. About 240 adults with serious bacterial infections will be randomly assigned to receive the drug either subcutaneousl…

This study compares two ways to treat Gram-negative bloodstream infections: staying on IV antibiotics versus switching to oral pills early. Researchers want to see if the oral option works just as well but causes fewer side effects. About 1,030 hospitalized adults will take part,…

This study compares two ways of giving the antibiotic cefepime to very sick patients with sepsis in the ICU. The new method adjusts the dose based on the patient's kidney function, using only standard doses. The main goal is to see if this approach is easy for doctors to use and …

This study tests whether pivmecillinam pills work as well as standard antibiotics for treating febrile urinary tract infections (kidney infections) in adults. Participants who have already improved after 2-4 days of IV antibiotics will take pivmecillinam or continue standard care…

This study tests whether giving zinc supplements along with standard antibiotics can reduce deaths and improve recovery in young infants (0-59 days old) hospitalized with severe infections like sepsis or pneumonia. About 3,250 babies in Tanzania will receive either zinc or a plac…

This study tests a new treatment called SNIPR001, which uses specially designed viruses to kill a type of antibiotic-resistant E. coli bacteria. The trial includes 24 adults with blood cancer who are scheduled for a stem cell transplant and already carry these resistant bacteria.…

This early study is testing a radioactive tracer called [18F]F-TMP that is injected into the body and then tracked with a PET/CT scan. The goal is to see if the tracer collects at sites of bacterial infection, making them visible on the scan. Twenty adults with known or suspected…

This study tests whether washing the bladder with a harmless strain of E. coli can prevent recurrent urinary tract infections (UTIs) in people who have failed other treatments. Researchers will compare the harmless bacteria wash to a saltwater wash in 80 participants, tracking ho…

This study tests whether giving antibiotics through a small, portable pump over 24 hours is safe and cost-effective for children with serious bacterial infections. About 150 kids who are stable enough for home care will receive the pump instead of multiple daily hospital injectio…

This study looks at how the immune system changes with age and how that affects the risk of infections in people 60 and older. Researchers will collect blood, urine, stool, and other samples from elderly patients with infections and healthy older adults. By analyzing immune cells…

This study aims to improve how doctors evaluate and manage people who have been exposed to bioterrorism agents (like anthrax) or emerging infectious diseases (like SARS or new flu strains). Up to 200 participants, including patients and healthcare workers, will be monitored and t…

This study is testing a new rapid diagnostic device called In-Dx to quickly identify infections and antibiotic resistance in emergency patients with suspected sepsis. Researchers will compare the device's results to standard lab cultures using stored samples from 2,500 patients. …

This study is observing 1,000 people with liver cirrhosis who have bacterial infections and are being treated with β-lactam antibiotics. Researchers want to see how the body processes these drugs and whether personalized dosing could improve survival. The study is observational, …

This study tests a new, lightweight ultrasound device called NeoDoppler that can be gently placed on a newborn's soft spot (fontanelle) to continuously measure blood flow in the brain. Researchers will enroll 180 preterm and full-term infants, including those with conditions like…

This study is looking at whether early signs of inflammation in the blood can help identify which patients with infections are at risk for serious complications like sepsis. Researchers will follow 4,200 adults with confirmed or suspected infections, as well as healthy controls, …

This early-stage study is testing whether a single dose of an experimental antibiotic combination (sulopenem etzadroxil plus probenecid) is safe and tolerable in 12 adolescents already receiving standard antibiotics for a bacterial infection. Researchers will measure how the drug…

This study looks at how the antibiotic ceftazidime avibactam behaves in 30 children with severe infections who are in intensive care, some on life support. Researchers will measure drug levels in the blood to understand the right dose. The goal is to improve treatment for life-th…

This study looks at how the antifungal medicine caspofungin behaves in children with severe infections, especially those with liver problems or on life support like ECMO. Researchers will measure drug levels in the blood to understand dosing needs. About 60 children in intensive …

This study will collect data from 2,000 children admitted to pediatric intensive care units (PICUs) with severe infections across major Chinese cities. Over 10 years, researchers will track which germs cause these infections, how they are treated, and patient outcomes. The goal i…

This study looks at two common antibiotic combinations given to hospitalized adults with infections: vancomycin plus piperacillin-tazobactam, or vancomycin plus cefepime. The goal is to see if one is less likely to cause kidney injury than the other, using more sensitive markers …
