The objective of the study was to characterize the safety of tedizolid phosphate (TR-701 FA) and the pharmacokinetics of tedizolid (TR-700), its microbiologically active moiety, in subjects with advanced renal impairment (eGFR <30 ml/minute/1.73 m2, not on dialysis) compared with matched subjects with normal renal function (eGFR ≥80.0 ml/minute/1.73 m2).
Eight subjects with advanced renal impairment and eight matched controls (by age, gender, and body mass index) received a single intravenous infusion of 200 mg TR-701 FA. Serial plasma PK samples were collected from pre-dose through 72 hours post-dose. Plasma samples were analyzed for TR-700 and the following pharmacokinetic parameters were calculated: Cmax, tmax, AUC0−∞, AUC0−t λz, CLsys, and plasma .

Advanced renal impairment
The TR-700 plasma pharmacokinetic results from this study provide support that no dose adjustment is needed in subjects with advanced renal impairment.
