About

This is a study to assess the pharmacokinetics (PK) of tedizolid phosphate and its active metabolite, tedizolid, and the safety of tedizolid phosphate following administration of a single IV (Part A) or oral suspension (Part B) administration to hospitalized participants ages 6 to <12 years (Groups 1 and 3, respectively), and 2 to <6 years (Groups 2 and 4, respectively).

Full description

Part A (IV): Group 1 (Cohort 1 and Cohort 2) (6 to <12 years) Group 2 (Cohort 1 and Cohort 2) (2 to <6 years) Part B (Oral Suspension): Group 3 (6 to <12 years) Group 4 (2 to <6 years) In Cohort 1 of Group 1 (IV) participants received a single administration of tedizolid phosphate at 5 mg/kg of total body weight. After all participants in Cohort 1 of Group 1 received study drug, a preliminary analysis of the safety and PK data was performed and results were used to select 4 mg/kg as the appropriate dose for Cohort 2 of Group 1 and Group 3, and to select 6 mg/kg as the starting dose for the younger participants, Cohort 1 of Group 2. After all participants in Cohort 1 of Group 2 receive study drug, another preliminary analysis of the safety and PK data will be performed and results will be used to confirm 6 mg/kg as the appropriate dose for Cohort 2 of Group 2. Similarly, the Group 4 dose will be confirmed after data review of Group 3 results.

  • Females must be premenarchal, abstinent, or practicing an effective method of birth control;

Exclusion criteria

  • History of seizures, other than febrile seizures, clinically significant cardiac arrhythmia, cystic fibrosis, moderate or severe renal impairment, or any physical condition that could interfere with the study results;
