This clinical trial is focused on studying aerobic Gram-negative bacterial infections in young children. These infections are caused by a type of bacteria that need oxygen to grow and can lead to serious health issues. The study will use a medication called cefiderocol, also known by its code name S-649266. Cefiderocol is a type of antibiotic that is given through an infusion, which means it is delivered directly into the bloodstream through a vein. The purpose of the study is to understand how cefiderocol behaves in the body and to check its safety and how well it is tolerated by the patients.
The study will involve children from birth to less than three months old who are hospitalized with suspected or confirmed Gram-negative bacterial infections. These infections can include conditions like complicated urinary tract infections, complicated intra-abdominal infections, hospital-acquired bacterial pneumonia, ventilator-associated bacterial pneumonia, and bloodstream infections or sepsis. The study will observe how the medication is processed in the body after both a single dose and multiple doses.
Throughout the study, researchers will monitor the children for any side effects and changes in vital signs, which are basic measures of health like heart rate and temperature. They will also conduct physical examinations and laboratory tests to ensure the safety of the participants. The study aims to provide valuable information on the use of cefiderocol in treating these serious infections in very young children.
