Trial Outcomes & Findings for Pharmacokinetic Study of Oral Gepotidacin (GSK2140944) in Subjects With Uncomplicated Urinary Tract Infection (Acute Cystitis) (NCT NCT03568942)

NCT ID: NCT03568942

Last Updated: 2020-06-29

Results Overview

Blood samples were collected to evaluate the PK of gepotidacin at the indicated time points. The PK parameters were calculated by standard non-compartmental analysis. PK Parameter Population consisted of all participants who received gepotidacin 1500 mg BID through the completion of all PK collections for whom valid and evaluable plasma PK parameters were derived for gepotidacin.

Population: Safety Population

An AEs is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. An SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect; and other important medical events which may require medical or surgical intervention. Safety Population consisted of all participants who received at least 1 dose of gepotidacin.

SECONDARY outcome

Timeframe: Baseline, Day 3, Day 5 and Days 10 to 13 (Test-of-cure visit)

Population: Safety Population. Only those participants with data available at the indicated time points were analyzed (represented by n= X in the category titles).

Urine samples were collected at indicated time points to analyze parameter including ketones by dipstick. The dipstick test gives results in a semi-quantitative manner, and results for urinalysis parameters can be read as negative, 5 indicates 5 milligrams per deciliter (mg/dL) and 20 indicates 20 mg/dL in the urine sample. Baseline was defined as Day -1. Assessment at Test-of-cure visit was conducted between any day of Days 10 to 13. Only categories with significant values have been presented.
