Eligibility |
Inclusion Criteria: - Males or females 12 years to <18 years - Adequate venous access for IV administration of study drug for at least 24 hours (for participants receiving IV medication) and collection of protocol-specified blood samples - Local symptoms must have started within 7 days before Study Day -1 - cSSTI meeting at least 1 of the clinical syndrome definitions. - Suspected or documented Gram-positive infection from baseline Gram stain or culture. - Parent/legally authorized representative (LAR) able to give informed consent and willing and able to comply with all required study procedures. Assent is also required of children who in the Investigator's judgment are capable of understanding the nature of the study Exclusion Criteria: - Uncomplicated minor skin and skin structure infections such as pustules, folliculitis, furuncles, minor abscesses (small volume of suppuration not surrounded by cellulitis/erysipelas), impetiginous lesions, superficial or limited cellulitis/erysipelas, and minor wound associated foreign body reactions (eg, stitch abscesses) - Known bacteremia, severe sepsis or septic shock - Recent history of opportunistic infections where the underlying cause of these infections is still active (eg, leukemia, transplant, acquired immunodeficiency syndrome) - Hypersensitivity to tedizolid phosphate or any component in the formulation - Hypersensitivity to all of the comparator drugs; hypersensitivity to a comparator drug does not preclude participation if an alternative comparator can be used - For participants with wound infections: history of hypersensitivity to ceftazidime, aztreonam, or any component of the aztreonam formulation, if aztreonam adjunctive therapy is required; history of hypersensitivity to metronidazole or any component of the formulation, if metronidazole adjunctive therapy is required - Needs oral administration of methotrexate, topotecan, irinotecan or rosuvastatin, during administration of oral study drug. - Uses monoamine oxidase inhibitors, tricyclic antidepressants, buspirone, selective serotonin reuptake inhibitors and serotonin 5 hydroxytryptamine receptor agonists (triptans) within 14 days prior to study drug administration |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Change From Baseline in Lesion Size | Lesion size is the area in cm^2 of erythema, edema or induration. A negative number corresponds to a decrease in lesion size. | Baseline and TOC visit (18 to 25 days after infusion) | |
Other | Peak Plasma Concentration (Cmax) of Tedizolid | The Cmax of tedizolid in plasma after the last dose was estimated based on population pharmacokinetic analysis of observed pharmacokinetic data. Blood samples were collected for pharmacokinetic analysis at specific time points. | Day 1 at 5-80 minutes (min) and 4-12 hrs post-infusion or 2 samples collected between 4-12 hrs after oral dose, at least 60 min apart; at 48-72 hrs: within 60 min prior to administration and 4-12 hrs after administration; and anytime between Day 7 and 9 | |
Other | Area Under the Plasma Concentration Versus Time Curve Time 0 to 24 Hours (AUC0-24h) of Tedizolid | AUC0-24h is a measure of the total tedizolid exposure in the plasma from the dose to 24 hours after last dose. AUC0-24h was estimated based on population pharmacokinetic analysis of observed pharmacokinetic data. Blood samples were collected for pharmacokinetic analysis at specific time points. | Day 1 at 5-80 min and 4-12 hrs post-infusion or 2 samples collected between 4-12 hrs after oral dose, at least 60 min apart; at 48-72 hrs: within 60 min prior to administration and 4-12 hrs after administration; and anytime between Day 7 and 9 | |
Primary | Number of Participants With Adverse Events on Tedizolid Phosphate and Comparator Drugs | An adverse event (AE) refers to a treatment-emergent adverse event (TE-AE). A TE-AE is any AE that newly appeared, increased in frequency, or worsened in severity following initiation of study drug. | Up to 40 days (including 30-day follow-up) | |
Secondary | Number of Participants With Investigator's Assessment Indicating Clinical Success at Test of Cure (TOC) Visit (Intent to Treat Analysis Set) | Investigator's assessment of clinical success is defined as (1) resolution or near resolution of most disease-specific signs and symptoms, (2)absence or near resolution of regional or systemic signs of infection (lymphadenopathy, fever, >10% immature neutrophils, abnormal white blood cell count), if present at baseline, and (3) no new signs, symptoms, or complications attributable to the infection under study so no further antibiotic therapy is required for the treatment of the primary lesion. | TOC Visit: 18-25 days after first drug infusion | |
Secondary | Number of Participants With Investigator's Assessment Indicating Clinical Success at TOC Visit (Clinically Evaluable-Test of Cure [CE-TOC] Analysis Set) | Investigator's assessment of clinical success is defined as (1) resolution or near resolution of most disease-specific signs and symptoms, (2)absence or near resolution of regional or systemic signs of infection (lymphadenopathy, fever, >10% immature neutrophils, abnormal white blood cell count), if present at baseline, and (3) no new signs, symptoms, or complications attributable to the infection under study so no further antibiotic therapy is required for the treatment of the primary lesion. | TOC Visit: 18-25 days after first drug infusion | |
Secondary | Number of Participants With Early Clinical Responses Measured by Lesion Reduction | Early clinical response is defined as =20% reduction from baseline lesion area (defined as length multiplied by the width of the erythema, edema, and/or induration [EEI]) at the 48-72 hour (hr) visit. | 48-72 hr after first drug infusion | |
Secondary | Number of Participants With Investigator's Assessment Indicating Clinical Success at End of Therapy (EOT) Visit (Intent to Treat Analysis Set) | Investigator's assessment of clinical success is defined as (1) resolution or near resolution of most disease-specific signs and symptoms, (2)absence or near resolution of regional or systemic signs of infection (lymphadenopathy, fever, >10% immature neutrophils, abnormal white blood cell count), if present at baseline, and (3) no new signs, symptoms, or complications attributable to the infection under study so no further antibiotic therapy is required for the treatment of the primary lesion. | EOT Visit: up to 13 days after first drug infusion | |
Secondary | Number of Participants With Investigator's Assessment Indicating Clinical Success at EOT Visit (Clinically Evaluable-End of Therapy [CE-EOT] Analysis Set) | Investigator's assessment of clinical success is defined as (1) resolution or near resolution of most disease-specific signs and symptoms, (2) absence or near resolution of regional or systemic signs of infection (lymphadenopathy, fever, >10% immature neutrophils, abnormal white blood cell count), if present at baseline, and (3) no new signs, symptoms, or complications attributable to the infection under study so no further antibiotic therapy is required for the treatment of the primary lesion. | EOT Visit: up to 13 days after first drug infusion |
