Hepatitis C Virus InfectionThe primary objective of this study is to evaluate the antiviral efficacy, safety, and tolerability of therapy with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) and ribavirin (RBV) in participants with chronic genotype 1 or 2 hepatitis C virus (HCV) infection who have previously failed a direct-acting antiviral (DAA)-containing regimen.

Study to Evaluate the Efficacy and Safety of Suptavumab (REGN2222) for the Prevention of Medically...
Respiratory Syncytial Virus InfectionsThe purpose of this study was to evaluate the efficacy, safety, pharmacokinetics (PK), and immunogenicity of suptavumab (REGN2222) in infants born no more than 35 weeks, 6 days gestational age who are no more than 6 months of age at the time of enrollment in their respective geographic location. In order to optimize the potential benefit in this vulnerable population, we conducted this study during the RSV season using dosing regimens that are expected to be effective.

Hepatitis C Virus InfectionThis study will evaluate the safety, tolerability, and antiviral efficacy of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) for 12 or 24 weeks in adults with chronic genotype 1 or genotype 4 hepatitis C virus (HCV) infection who have had a kidney transplant.

Pharmacokinetic and Safety Study of Ceftolozane/Tazobactam in Pediatric Participants Receiving Antibiotic...
Proven or Suspected Gram-negative Bacterial InfectionPeri-operative ProphylaxisThe purpose of this study was to assess the pharmacokinetics, safety, and tolerability of a single intravenous dose of ceftolozane/tazobactam (MK-7625A) in pediatric participants. In each of the 6 age cohorts, an interim analysis of pharmacokinetics (PK) and safety data was conducted after approximately 3 participants had received the initially proposed dose. The interim analysis was to determine whether the initial dose was appropriate based on pre-defined criteria. If data from the interim analysis demonstrated that the initially proposed dose met the above criteria, enrollment was to continue with the same dose administered to approximately 3 additional participants of the same age range. However, if the interim analysis demonstrated that a new optimized dose was required, the new dose was to be administered to approximately 3 additional participants of the same age range.

MicroUDxTM: a Rapid Diagnostic Tool That Will Prevent Death and Disability From Common Infections...
Bacterial Urinary Tract InfectionBackground & Rational: Antibiotics are a major underpinning of modern medicine. The global rise of antimicrobial resistant (AMR) organisms is a serious world health problem. With few new antimicrobial drugs on the horizon, it is imperative that we develop novel approaches to extend the service life of our existing drugs. AMR is a complex problem that is being driven by a wide range of factors. More than half of the antibiotics prescribed have no medical benefit, and outpatient visits for uncomplicated urinary tract infections (UTIs) are a major contributor to this problem. Recent studies have shown that nearly half of people treated for UTIs receive the wrong frontline drug and in 75% of patients, the duration of therapy is inappropriate. Limitations in the current diagnostic technology make it impossible to identify UTI pathogens and measure their antibiotic sensitivities during the short out-patient clinical visits that are typical for most UTI patients. These circumstances result in the inappropriate use of stronger than necessary or inappropriate antimicrobials. The aim of this study is to develop and evaluate a system that can detect bacteria in urine and find the best antibiotic in under 4 hours, thus enabling a rapid diagnosis and use of the most appropriate and cost-effective antimicrobial agent for the agent detected.
