Clinical Trial Summary

This study will be conducted to determine if altered renal function affects the plasma pharmacokinetics of gepotidacin, which will inform if dosing recommendations based upon renal impairment are required. The objective of this study is to compare the pharmacokinetics of gepotidacin administered as a 750 milligram (mg) intravenous (IV) dose in normal healthy subjects compared with subjects with mild, moderate, and severe renal impairment, and with subjects with end stage renal disease (ESRD). This is a Phase I, nonrandomized, open-label, parallel-group, multi-center, multi-part study. In Part 1, up to 16 subjects with normal renal function will be matched to approximately 8 subjects with moderate renal impairment, and approximately 8 subjects with severe renal impairment and/or subjects with ESRD not on hemodialysis for a total of approximately 32 subjects. In Part 2 (optional), approximately 4 to 8 subjects with normal renal function (if enrolled), approximately 4 to 8 subjects with mild renal impairment, and approximately 4 to 8 subjects with ESRD on hemodialysis will be enrolled for a total of approximately 12 to 24 subjects. The duration from Screening to the Follow-up Visit will be approximately 44 days for Part 1 and approximately 50 days for Part 2.

Vz is the apparent volume of distribution at terminal phase. Volume of distribution of the terminal phase was calculated as total administered dose of gepotidacin divided by AUC (0-inf) multiplied by the rate constant.	Pre-dose, 0.25 , 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24, 36 and 48 hours post-dose during treatment period 1 and 2 both.
Secondary	Cumulative Amount of Drug Excreted in Urine From Time t1 to t2 (Ae[t1-t2]) of Gepotidacin for Part 1, for Normal	Ae (t1-t2), measure the amount of drug excreted in urine in a time intervals for predose, 0 to 6, 6 to 12, 12 to 24, or 24 to 36, and 36 to 48 hours after dosing for participant's with renal impairment; and predose, 0 to 2 hours, 2 to 4 hours, 4 to 6 hours, 6 to 8 hours, 8 to 12 hours, 12 to 24 hours, 24 to 36 hours, and 36 to 48 hours for participant's with normal renal function.	At Pre-dose, 0 to 2 hours, 2 to 4 hours, 4 to 6 hours, 6 to 8 hours, 8 to 12 hours, 12 to 24 hours, 24 to 36 hours, and 36 to 48 hours
Secondary	Cumulative Amount of Drug Excreted in Urine From Time t1 to t2 (Ae[t1-t2]) of Gepotidacin for Part 1, for Moderate and Severe	Ae (t1-t2), measure the amount of drug excreted in urine in a time intervals for predose, 0 to 6, 6 to 12, 12 to 24, or 24 to 36, and 36 to 48 hours after dosing for participant's with renal impairment. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).	at pre-dose (0.0), 0 to 6 hours, 6 to 12 hours, 12 to 24 hours, 24 to 36, and 36 to 48 hours post-dose during the single treatment period
Secondary	Ae(t1-t2) of Gepotidacin for Part 2	Ae (t1-t2), measure the amount of drug excreted in urine in a time intervals for predose, 0 to 6, 6 to 12, 12 to 24, or 24 to 36, and 36 to 48 hours after dosing for participant's with renal impairment; and predose, 0 to 2 hours, 2 to 4 hours, 4 to 6 hours, 6 to 8 hours, 8 to 12 hours, 12 to 24 hours, 24 to 36 hours, and 36 to 48 hours for participant's with normal renal function. NA indicates data is not available due to insufficient participants.Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).	Pre-dose (0.0), 0 to 8 hours, 8 to 12 hours, 12 to 24 hours, 24 to 36 hours, and 36 to 48 hours post-dose during both treatment period 1 and 2
Secondary	Total Amount of Unchanged Amount of Drug Removed by Hemodialysis (Arem) From Time 0 to 1 Hour After the Start of Hemodialysis (Arem[0-1]), Arem (1-2), Arem (2-3), Arem (3-4) for Part 2	Arem is defined as the total amount of drug removed using the hemodialysis method at different timepoints namely Arem (0-1), measured the amount of drug removed by hemodialysis from time 0 to 1 hour after the start of hemodialysis; Arem (1-2), measured the amount of drug removed by hemodialysis from time 1 to 2 hours after the start of hemodialysis; Arem(2-3) ), measured the amount of drug removed by hemodialysis from time 2 to 3 hour, Arem (3-4), measured the amount of drug removed by hemodialysis from hemodialysis from time 3 to 4 hours after the start of hemodialysis (or to the end of dialysis if <4 hours). Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).	Pre-dose, 0-1 hours, 1-2 hours, 2-3 hours and 3-4 hours post-dose on Day 1 in Period 1Dialysate fluid were collected at 1, 2, 3, and 4 hours post-dose in Period 1 only
