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 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 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 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 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 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…
