Study Endpoints
Primary Endpoints
Number of Participants Who Experienced an Adverse Event (AE)
Up to approximately 35 days

An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. Number of participants who experienced an AE were reported.

Number of Participants Who Discontinued Study Treatment Due to an AE
Up to approximately day 15

An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. Number of participants who experienced an AE were reported. The number of participants who discontinued study treatment due to an AE were reported.

Number of Participants With Hematopoietic Cytopenias
Up to approximately 35 days

Hematopoietic cytopenia is a condition where there is a lower-than-normal amount of one or multiple kinds of blood cells. A standardized Medical Dictionary for Regulatory Activities (MedDRA) query for hematopoietic cytopenia was conducted. The number of participants with a hematopoietic cytopenia were reported.

Cohort 1: Comparator 6 to <12 YearsACTIVE_COMPARATORParticipants will receive comparator IV and/or oral per local standard of care for 10 to 14 days.
Cohort 2: Tedizolid phosphate 2 to <6 YearsEXPERIMENTALParticipants will receive tedizolid phosphate once-daily single 200-mg dose (body weight ≥50 kg) or twice-daily 2-mg/kg doses (body weight 30 kg to \<50 kg); or twice-daily 2.5-mg/kg doses (body weight 3.2 kg to \<30 kg), by IV and/or oral suspension for 6 to 10 days.
Cohort 2: Comparator 2 to <6 YearsACTIVE_COMPARATORParticipants will receive comparator IV and/or oral per local standard of care for 10 to 14 days.
Cohort 3: Tedizolid phosphate 28 Days to <2 YearsEXPERIMENTALParticipants will receive tedizolid phosphate once-daily single 200-mg dose (body weight ≥50 kg) or twice-daily 2-mg/kg doses (body weight 30 kg to \<50 kg); or twice-daily 2.5-mg/kg doses (body weight 3.2 kg to \<30 kg), by IV and/or oral suspension for 6 to 10 days.

Cohort 4: Tedizolid phosphate Birth to <28 Days Term and Preterm NeonatesEXPERIMENTALParticipants will receive tedizolid phosphate ≤200 mg daily dose, IV and/or oral suspension for 6 to 10 days. Exact mg/kg dose is to be determined based on results of another study (NCT03217565) covering the age range.
