Staphylococcus Aureus, Ventilator Associated Pneumonia

Brief summary

Clinical trial looking at safety and efficacy of suvratoxumab in prevention of pneumonia caused by Staphylococcus aureus in high-risk patients

Detailed description

This is a Phase 3, randomized, double-blind, placebo-controlled study evaluating the efficacy of a single IV dose of suvratoxumab in mechanically ventilated subjects in the ICU who are at high risk for S. aureus infections and who are currently free of active S. aureus-related disease but are colonized with S. aureus in the LRT.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of nosocomial all-cause pneumonia through 30 days post dose30 daysAll-cause pneumonia is based on clinical, radiographic, and microbiologic criteria. The percent reduction of the incidence of (% of patients with) nosocomial all-cause pneumonia, regardless of identified etiology, following administration of study drug through 30 days post dose

Secondary

MeasureTime frameDescription
Number of participants with TESAE at 90 days90 daysTreatment emergent serious adverse events (TESAE) are serious adverse events (SAEs, AEs resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience; persistent or significant disability/incapacity; congenital anomaly) that, as TEAEs, are present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug, through 90 days
Number of participants with TEAESI at 90 days90 daysA TEAE of special interest (TEAESI) is an AE of scientific and medical interest specific to understanding of the study drug and may have required close monitoring and rapid communication by the investigator to the sponsor. An AESI may have been serious or non-serious. The time-frame is 90 days.
Number of Participants with Nosocomial all-cause pneumonia or death through 30 days post dose30 daysAll-cause pneumonia is based on clinical, radiographic, and microbiologic criteria. The percent reduction of the incidence of (% of patients with) nosocomial all-cause pneumonia, regardless of cause, or death following administration of study drug through 30 days post dose
Number of Participants with Nosocomial S. aureus pneumonia through 30 days post dose30 daysS. aureus pneumonia is based on clinical, radiographic, and microbiologic criteria. The percent reduction of the incidence of (% of patients with) nosocomial S. aureus pneumonia following administration of study drug through 30 days post dose
Number of participants with TEAE at 30 days30 daysTreatment emergent adverse events (TEAE) are those adverse events (AEs, any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship) that occur or worsen during the treatment period, i.e., after the administration of study drug, through 30 days post dose
Suvratoxumab Maximum Observed Serum Concentration (Cmax)90 daysMaximum Observed Serum Concentration (Cmax) of suvratoxumab at Day 0 (Pre-dose, end of the infusion, 8 and 24 hours post dose), and on Days 7, 30 and 90. At Day 90 only for a subset of patients.
Suvratoxumab Area under the Plasma Concentration-Time Curve (AUC)90 daysthe area under the plasma concentration-time curve (AUC) will be measured from time 0 to Day 30 (AUC0-30), in all study subjects, and AUC from time 0 to Day 90 (AUC0-90) for a subset of subjects
Number of Participants With Positive Anti-Drug Antibodies (ADA) Titer to Suvratoxumab90 daysThe incidence of (number of patients with) positive anti-drug antibodies (ADA) titer to suvratoxumab will be assessed and summarized by number and percentage of subjects that are ADA positive at predose, Day 30 in all subjects and Day 90 in a subset of patients.
Number of Participants with Nosocomial S. aureus pneumonia through 90 days post dose90 daysS. aureus pneumonia is based on clinical, radiographic, and microbiologic criteria. The percent reduction of the incidence of (% of patients with) nosocomial S. aureus pneumonia following administration of study drug through 90 days post dose
