This is an open-label, single-arm, pharmacokinetic and safety study of Likmez® in pediatric patients aged 12 months to \<4 years with anaerobic bacterial infection

A Phase 1, Open-label, Single-dose Study to Determine the Safety and Pharmacokinetics of Intravenous Cefiderocol/Xeruborbactam (S-649228) in Participants with Renal Impairment

The purpose of this study is to evaluate the abilities of Cystatin C (CysC) and CysC-based estimated Glomerular Filtration Rate (eGFR) equations to characterize the pharmacokinetics (PK) profiles of meropenem and cefepime relative to Serum Creatinine (SCR), Serum Creatinine based Equation (SCRE)and iohexol at the population and individual levels in critically ill adult patients with suspected or documented AMR Gram-negative infections. We hypothesize that CysC and CysC-based eGFR equations will characterize the PK profiles of meropenem and cefepime at the population and individual levels with greater accuracy and precision than SCR and SCREs. Iohexol will be administered to patients enrolled in the study and serve as the reference indicator of measured Glomerular Filtration Rate (mGFR), which is the gold standard assessment of kidney function. We hypothesize that the predictive performances of CysC and CysC-based eGFR equations in estimating the PK profiles of meropenem and cefepime at the population and individual levels will be comparable to iohexol. The information obtained in this study will be used to develop PK/pharmacodynamics (PD) optimized meropenem and cefepime dosing schemes based on the renal function biomarker population PK (PopPK) model with the best predictive performance for clinical use in the treatment of critically ill adult patients with suspected or documented AMR Gram-negative infections and varying degrees of renal function. The primary objective of this study is to compare the abilities of renal function biomarkers (CysC, CysC-based eGFR equations, SCR, SCREs) relative to iohexol to characterize the PK profiles of meropenem and cefepime in critically ill adult patients with suspected or documented AMR Gram-negative infections.

Cat bites are puncture wounds that have the potential to seed bacteria deep within the joint capsule, periosteum, and bone. The hand is the most common site of bite injuries. Pasteurella multocida is the is the most common organism isolated from the mouths of cats that can cause infections after a bite. Prophylactic antibiotics are often recommended with amoxicillin-clavulanate for 3-5 days to decrease the incidence of developing an infection. However, only one randomized controlled clinical trial consisting of 12 patients has been performed to justify this course of treatment, raising the possibility that the use of antibiotics could be reduced or even eliminated. Investigators will compare different durations of prophylactic antibiotics and a placebo control for cat bites to the hand/forearm presenting to the Emergency Department, Urgent Care, Plastic Surgery Clinic using a randomized, controlled, double-blind clinical trial. Participants presenting to the University of Missouri Hospital Emergency Department, Missouri University (MU) Healthcare Urgent Care, Plastic Surgery Clinic over the next year will be offered the chance to enroll if they meet the inclusion/exclusion criteria. For inclusion, participants will be \>18 years of age, have cat bites to the hand or distal to elbow, and present within 24 hours of the cat bite injury. Participants must not present with active local or systemic infections, have received antibiotics within the past 30 days, or be immunocompromised (primary and secondary immunodeficiencies). Participants will be randomized to one of three treatment arms (placebo; amoxicillin-clavulanate 1 day; amoxicillin-clavulanate 5 days). Outcomes are the development of an infection at the location of the cat bite and/or systemic infection, adverse effects of interventions, disability assessed by Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) scores, and quality of life (QOL) assessed by HAND Questionnaire (HAND-Q) scores. Infection will be assessed at day 0, day 2, day 7+/-2, day 14+/-2, and day 30+/-2 by vital signs, laboratory values, physical examination and with an infrared and digital camera. All measures will be within the standard of care, apart from the infrared camera, QuickDASH, and HAND-Q scores. The anatomic locations of cat bites to the hand/forearm will be assessed for correlations with infections.

The purpose of this study is to study a radioactive tracer, a type of imaging drug that is injected into the body to see how it is taken up in sites of active infection using an imaging procedure called Positron Emission Tomography/Computed Tomography (PET/CT).

Our data suggest that modulating the characteristics of light carries the potential to modify the host response to injury and critical illness and thus, improve outcome. The ability to modify the host response to the stress of major operations and sepsis carries immense potential to improve patient care. The primary purpose of this study is to determine if exposure to bright blue (442nm) enriched light, by comparison to ambient white fluorescent light, reduces the inflammatory response or organ dysfunction in patients undergoing 1) medical treatment for pneumonia, 2) a 2-stage arthroplasty for surgical management of a septic joint, 3) surgery for a necrotizing soft tissue infection (NSTI), and 4) surgery for an intraabdominal infection (e.g., diverticulitis). We will expose participants to one of two (2) lighting conditions: 1) high illuminance (\~1700 lux,), blue (442nm) spectrum enriched light and 2) ambient white fluorescent light that provides the standard environmental lighting (\~300-400 lux, no predominant spectrum) of the hospital. Both cohorts will be exposed to a 12 hours:12 hours light:dark cycle photoperiod. Those subjects assigned to blue light will be asked to shine this small portable blue enriched light on themselves from 0800 to 2000 for 3 days. At the transition from light to dark, the blue-enriched light is turned off, and additional blue wavelength light removed with an amber filter. Thus, the total period of intervention is 72 hours. The outcome of interest is change in the inflammatory response after surgery for appendicitis or diverticulitis as measured by the following parameters: white blood cell count, heart rate, the development of abdominal abscess, serum cytokine concentrations. The outcome of interest is change in the inflammatory response during pneumonia as measured by the following parameters: white blood cell count, heart rate, and serum cytokine concentrations.
