ECG=electrocardiogram; HIV=human immunodeficiency virus; PK=pharmacokinetic; TOC=Test-of-Cure; WBC=white blood cell.
a.
If a participant discontinues during the on-treatment confinement period, Day 5 assessments will be completed before the participant is discharged, with the exception of study 
treatment administration.
b.
Based on confirmation of pyuria (≥10 WBC/mm3 or the presence of leukocyte esterase) and/or nitrite from a pretreatment clean-catch midstream urine sample per local laboratory 
procedures. Note: Repeat baseline urine samples are allowed if contamination, defined as ≥10 squamous epithelial cells, is observed under microscopic evaluation.
c.
Participants will provide a clean-catch midstream urine sample pretreatment at Baseline (predose on Day 1), predose on Days 2 through 5 (i.e., before the time-matched dose); and 
at the TOC and Follow-up Visits for Gram stain, quantitative bacteriology culture, and in vitro antimicrobial susceptibility testing.
d.
Site staff will record clinical signs and symptoms of acute cystitis based on participant interview (see Appendix 10).
e.
Obtain a triplicate 12-lead ECG in semi-supine position at Baseline only. See Table 2 for single 12-lead ECG predose and postdose assessment time points on Days 1 and 4.
f.
Only repeat the ECG and vital sign assessments at predose on Day 1 if the baseline assessment was not within 4 hours of the first dose of study treatment.
g.
Take measurement of temperature, blood pressure, and pulse rate in semi-supine position.
h.
If serology testing was performed within 3 months prior to the first dose of study treatment and results were positive, testing at Baseline is not required. If testing was performed 
within 3 months and any result was negative, testing at Baseline is required.
i.
For women of childbearing potential, a negative serum pregnancy test is needed for eligibility at Baseline. A urine pregnancy test may be performed on Day 5 and at the TOC Visit.
j.
The first dose on Day 1 will only be administered after all baseline procedures have been completed. All doses of study treatment will be administered under site staff supervision 
and all doses will be administered with food (i.e., standardized meals or snacks as applicable). Participants should remain in the clinic to complete a total of 10 doses.
k.
See Table 2 for serial collection time points. Predose PK blood samples will be collected before each time-matched dose on Days 1 through 5. Predose PK urine samples will be 
collected 0 to 2 hours before each time-matched dose on Days 1 through 5. Only 1 sample is needed when serial and predose samples overlap. If a participant is switched to a 
different antibiotic before the end of study treatment, a final blood and urine PK sample should be collected prior to administration of the different antibiotic.
l.
Collection of cervical, rectal, and pharyngeal swab PK specimens is optional. Specimens will be collected on Day 4 at predose and at approximately 2 hours postdose. The 2-hour 
postdose collection should be as close as possible to the 2-hour postdose blood PK draw time on Day 4.
m.
Collect sample only if the participant has a signed consent specific for this purpose. Baseline (predose on Day 1) is the recommended time to collect the sample, but it can be 
collected at any time during the study.
n.
Collection of stool, vaginal, and pharyngeal microbiome specimens is optional. The pretreatment specimens may be collected any time from Day -1 to Day 1 predose. The 
posttreatment specimens on Day 5 and at Follow-up may be collected at any time. Posttreatment stool, vaginal, and pharyngeal microbiome specimens should only be collected 
from participants who had a corresponding baseline specimen collected for each specimen type. 
o.
Record serious adverse events from the time of consent.
p.
Record adverse events from the time of the first dose of study treatment.
q.
Confirm return day/time for the TOC and Follow-up Visits.
r.
Pre-visit reminder: Site staff will contact the participant 24±4 hours before the scheduled TOC and Follow-up Visits.
Note:
At the discretion of the investigator, for emergency purposes only, participants may temporarily leave the clinic on study days without serial PK collections and only at times that do not 
interfere with required study assessments. Participants will be instructed to follow the protocol restrictions. The investigator will ensure the participant is eligible to continue in the study 
upon return to the clinic. All doses of study treatment will be administered under site staff supervision in the clinic.
The timing and number of planned study assessments, including PK assessments may be altered during the study based on newly available data (e.g., to obtain data closer to the time of 
peak plasma concentrations) to ensure appropriate monitoring. Any changes in the timing or addition of time points for any planned study assessments must be documented and 
approved by the relevant study team member and then archived in the sponsor and site study files, but will not constitute a protocol amendment. The institutional review board will be 
informed of any safety issues that require alteration of the safety monitoring scheme or amendment of the informed consent form.

INTRODUCTION
Gepotidacin (GSK2140944), a novel triazaacenaphthylene bacterial type II 
topoisomerase inhibitor, is being developed for the treatment of uncomplicated urinary 
tract infections (UTIs; acute cystitis). Gepotidacin is also being developed as an oral and 
intravenous treatment for infections caused by conventional and biothreat pathogens, 
including isolates resistant to existing classes of antimicrobials. The microbiological 
spectrum of activity of gepotidacin includes Escherichia coli, the key causative pathogen 
of acute cystitis, and Staphylococcus saprophyticus and Enterococcus faecalis.
Gepotidacin selectively inhibits bacterial DNA replication by interacting in a unique way 
on the GyrA subunit of bacterial DNA gyrase and the ParC subunit of bacterial 
topoisomerase IV. This interaction appears to be highly specific to bacterial 
topoisomerases as evidenced by weak in vitro inhibition of human topoisomerase II, 
supporting the selective activity of gepotidacin against the bacterial target. The novel 
mode of action of this new class antibacterial affords in vitro activity against most target 
pathogens resistant to established antibacterials, including fluoroquinolones.
3.1.
Study Rationale
This Phase IIa study is designed primarily to evaluate plasma and urine pharmacokinetics
of gepotidacin in female participants with acute cystitis.
This study is being conducted based on the need to identify new and effective oral 
antibiotic treatment options for acute cystitis, as such therapies are becoming limited due 
to the increase of multidrug-resistant (MDR) pathogens and extended-spectrum 
-lactamase (ESBL)-producing Enterobacteriaceae pathogens, which are impacting the 
efficacy of currently available oral antibacterial treatment options (see Section 3.2). 
Two Phase II studies have been conducted and the results demonstrated that gepotidacin 
was efficacious in the treatment of uncomplicated urogenital gonorrhea and acute 
bacterial skin and skin structure infections (ABSSSIs) (see Section 5.3.3 in the
investigator’s brochure [IB] for details).
3.2.
Background
Urinary tract infections are very common, with approximately 11% of women >18 years 
of age experiencing at least 1 episode of acute cystitis per year [Foxman, 2000]. Of these, 
half will experience more than 1 recurrent episode over their lifetime [Foxman, 2000]. 
The peak incidence of acute cystitis occurs in young, sexually active women ages 18 to 
29 years [Fihn, 2003]. The predominant uropathogen isolated in community-acquired 
UTIs is E. coli (75% to 90%) followed by S. saprophyticus (5% to 15%) [Stamm, 1993;
Talan, 2000; Foxman, 2010]. Klebsiella, Enterobacter, and Proteus species and 
enterococci are observed in only 5% to 10% of cases [Stamm, 1993; Talan, 2000;
Foxman, 2010].
Multidrug resistance, which is typically associated with nosocomial infections, has now 
emerged at the community level and has made treatment approaches for UTIs more 
difficult [Hooton, 2012; Flamm, 2014; Sanchez, 2016]. This has led to increasing patient

12
morbidity, increasing costs due to reassessment and retreatment, higher rates of 
hospitalization, and increased use of broad-spectrum antibiotics [Foxman, 2002; Gupta, 
2011a; Hooton, 2012]. Furthermore, ESBL-producing Enterobacteriaceae, which 
includes E. coli, is recognized as a serious threat by the Centers for Disease Control and 
Prevention (CDC) [CDC, 2013] and drug-resistant Enterobacteriaceae is a critical 
priority pathogen for the World Health Organization (WHO) [WHO, 2017]. One reason 
for this serious threat level is the growing rise in the MDR E. coli sequence type 
(ST)-131 clone [Johnson, 2012; Nicolas-Chanoine, 2014]. Spread of this ST-131 clone 
has led to UTIs and blood stream infections caused by MDR E. coli worldwide [Peirano, 
2010]. The availability of oral antimicrobials that are effective against ESBLs is limited 
and, for some outpatient infections, no oral options remain.
An in vitro evaluation of antimicrobial resistance of urinary E. coli isolates 
(n=12,253,679) among US outpatients between 2000 and 2010 was conducted using 
The Surveillance Network and found significant increases in the percentage of E. coli that 
were resistant to ciprofloxacin (3% to 17.1%) and trimethoprim-sulfamethoxazole 
(TMP-SXT) (17.9% to 24.2%), whereas there were minimal changes in the percentage of 
resistance to nitrofurantoin (0.8% to 1.6%) and ceftriaxone (0.2% to 2.3%) over time 
[Sanchez, 2012]. Another surveillance study, which looked at US susceptibility patterns 
and ESBL rates of E. coli from UTIs, showed an increase in ESBL rates from 7.8% to 
18.3% (p<0.0001) from 2010 to 2014 [Lob, 2016]. The expansion of ESBL-producing 
E. coli, which are usually co-resistant to TMP-SXT and fluoroquinolones, is of urgent 
concern globally as well [Oteo, 2010]. Recent global surveillance data of E. coli showed 
high resistance rates to third-generation cephalosporins and fluoroquinolones in all 
6 WHO regions [WHO, 2014]. An evaluation of the prevalence and susceptibility of 
acute cystitis pathogens in 9 European countries and Brazil from 2003 to 2006 showed 
that >10% of E. coli strains were MDR and 1.7% were ESBL producers [Schito, 2009]. A 
separate study in Brazil reported a prevalence of 7.6% ESBL-producing 
Enterobacteriaceae among pathogens from community-acquired UTIs [Abreu, 2013]. In 
China, the prevalence of ESBLs in urinary E. coli in women ranged from 5% to 10.6% 
depending on the age group [Ho, 2007]. 
Based on these resistant pathogen trends, guidelines for acute cystitis now recommend 
first-line antibiotic treatment with nitrofurantoin, TMP-SXT, fosfomycin, or 
pivmecillinam, assuming the drug is available and the patient does not have a concerning 
allergy history or tolerance issues [Gupta, 2011b]. Trimethoprim-sulfamethoxazole 
should not be used as a first-line treatment if the prevalence of resistance exceeds the 
20% threshold or if TMP-SXT was used for treatment of a UTI in the previous 3 months. 
If any of these are concerns for a patient, then fluoroquinolones or β-lactams are 
recommended.
Gepotidacin is a first-in-class, novel triazaacenaphthylene antibacterial that has 
demonstrated in vitro activity against uropathogens including E. coli (see Section 4.2 of 
the IB for details) and provides high and sustained urine concentrations for the treatment 
of UTIs. With its unique ability to selectively inhibit bacterial DNA replication by a 
means not utilized by any currently approved human therapeutic agent, gepotidacin 
warrants further study as a potential opportunity to address an unmet medical need by 
providing a new and effective oral treatment option for acute cystitis.

Gepotidacin (e.g., GSK2140944)
Cardiovascular Effects
Based on nonclinical data, cardiovascular effects 
were reversible increase in heart rate and blood 
pressure (dog and monkey); reversible 10 to 
21 msec (4% to 9%) increase in QTc (monkey); 
and at the highest dose, a reversible 2 to 3 msec 
(6% to 8%) increase in QRS (monkey).
Based on a thorough QTc clinical study, 
gepotidacin may cause mild, reversible heart rate 
effects and QT prolongation.
In a thorough QTc study, infusion of gepotidacin 
at doses of 1000 and 1800 mg over 2 hours 
caused a mild increased heart rate effect of 
approximately 6 to 10 bpm and QT prolongation 
measured as ∆∆QTcF of 12 to 22 msec. The QT 
prolongation evolved during the infusion and was 
quickly reversed over 2 hours after the end of the 
infusion (see Section 5.2.6 and Section 6 of the 
IB).
No changes in QRS or QTc of clinical concern 
have been seen in the clinic (Phase I studies and 
Phase II ABSSSI study) (see Section 6 in the IB). 
Cardiovascular events reported in the Phase II 
urogenital gonorrhea study were ECG ST 
segment elevation and palpitations (1 participant 
each) in the 1500-mg treatment group and 
tachycardia (1 participant) in the 3000-mg 
treatment group.
See Section 6.2 for excluded cardiac conditions. 
Close monitoring of clinical parameters and AEs 
(Table 1) will be conducted, and treatment 
monitoring and evaluation criteria (Section 8.1.2) 
will be utilized to mitigate cardiovascular effects.
As a consequence, participants taking 
QT-prolonging drugs or strong CYP3A4 inhibitors 
and/or strong P-gp inhibitors will be excluded.

Summary of Data/Rationale for Risk
Mitigation Strategy
Gastrointestinal Effects
Based on nonclinical data, gastrointestinal 
effects were mild ulceration of the nonglandular 
mucosa and minimal erosion and/or mural 
inflammation of the glandular mucosa in stomach 
(rat, oral study); moderate cecal ulceration and 
minimal colonic erosion (rat, IV study); and 
vomiting (dog).
Lower gastrointestinal effects (soft stools, 
flatulence, and diarrhea) are among the most 
common AEs reported in gepotidacin clinical 
studies.
Gastrointestinal effects observed in gepotidacin
clinical studies, both Phase I studies and the 
Phase II ABSSSI study, included diarrhea (very 
common, ≥10%) and flatulence (common; ≥1% 
and <10%); all nonserious and mild in severity 
(see Section 6 of the IB).
In the Phase II urogenital gonorrhea study, the 
most frequently reported gastrointestinal AEs 
overall were diarrhea, flatulence, abdominal pain, 
and nausea. Comparing the treatment groups, 
the incidence of diarrhea and nausea was higher 
in the 3000-mg treatment group and incidence of 
flatulence was higher in the 1500-mg treatment 
group. 
Few occurrences of Clostridium difficile have 
been reported in clinical studies (see Section 6 of 
the IB). Of the 357 healthy participants in Phase I 
studies who have received gepotidacin, 
C. difficile was reported in 8 participants, 
including 2 elderly participants in association with 
soft stools or diarrhea. No participants in the 
Phase II ABSSSI or Phase II urogenital 
gonorrhea study received a diagnosis of 
C. difficile-associated diarrhea.
See Section 6.2 for excluded medical conditions. 
Close monitoring of clinical parameters and AEs 
(Table 1) will be conducted to mitigate and 
assess gastrointestinal effects. Suspected 
C. difficile infection will be managed according to 
a prespecified algorithm provided in the Study 
Reference Manual.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
Acetylcholinesterase Inhibition
In a mass spectrometry model performed with 
gepotidacin, acetylcholinesterase was inhibited 
with an IC50 of approximately 5 g/mL 
(7.5 g/mL of total drug concentration).
Based on clinical data, caution should be used in 
participants who have a condition requiring 
medication that may be exacerbated by 
acetylcholinesterase inhibition or 
neuromuscular-blocking agents.
Adverse events consistent with 
acetylcholinesterase effects were reported 
infrequently in Phase I studies as single or 
combined AEs, including dizziness, abdominal 
pain, oropharyngeal discomfort, salivary 
hypersecretion, hot flush, diarrhea, fatigue, and 
nausea. In the Phase II ABSSSI study with IV or 
oral treatment with gepotidacin up to 10 days, 
AEs of diarrhea, nausea, dizziness 
(1 participant), salivary hypersecretion 
(1 participant), and hot flush (1 participant) were 
reported (see Section 6 of the IB).
In the Phase II study of urogenital gonorrhea 
(oral doses: 1500 or 3000 mg), treatment-related 
AEs potentially associated with 
acetylcholinesterase inhibition included dizziness 
(1 and 6 participants, respectively), hyperhidrosis 
(1 and 6 participants, respectively), and 
headache (2 participants in both).
Participants who have medical conditions or 
require medications that may be aggravated by 
inhibition of acetylcholinesterase will be excluded 
from participation in this study. See Section 6.2
for excluded medical conditions and 
Section 7.7.2, Prohibited Medications and 
Nondrug Therapies, for prohibited medications.
Close monitoring of clinical parameters and 
AEs will be conducted to assess effects 
potentially related to acetylcholinesterase 
inhibition (Table 1).

3.3.2.
Benefit Assessment
Given gepotidacin’s spectrum of activity against E. coli, S. saprophyticus, and 
E. faecalis, as well as human safety data and the pharmacokinetic (PK) profile, it is 
anticipated that gepotidacin will benefit participants with acute cystitis.
Overall, all participants in this study will not only receive routine medical monitoring
appropriate for acute cystitis, but they will also receive heightened monitoring to ensure 
safety when participating in a clinical study.
The PK data from this study will be used to support the indication for gepotidacin as a 
potential new treatment option for acute cystitis.
3.3.3.
Overall Benefit:Risk Conclusion
Together with the known preclinical data for gepotidacin against E. coli, 
S. saprophyticus, and E. faecalis, cumulative safety results from Phase I and Phase II 
studies with oral gepotidacin treatment, and the PK data from this study will be used to 
support the indication for gepotidacin as a potential new treatment option for acute 
cystitis.
None of the potential or identified risks seen to date in participants dosed with 
gepotidacin preclude further clinical development. Mitigation strategies have been 
implemented to promptly identify and appropriately address risks in order to protect 
participant safety and to better characterize the safety profile of the study treatment 
(Section 3.3.1), including additional 12-lead ECG assessments during the study while 
participants are confined. Careful safety monitoring should also identify any emerging 
safety issues for gepotidacin and contribute to further benefit-risk profile development.
The investigator may, at his or her discretion, discontinue the participant from study 
treatment at any time and initiate appropriate alternative therapy.
Taking into account the measures taken to minimize risk to participants participating in 
this study, the potential risks identified in association with gepotidacin are justified by the 
anticipated benefits that may be afforded to participants with acute cystitis.

Overall Design
A study design schematic is depicted in Figure 1.

Study 206889 is a Phase IIa single center, open-label study evaluating the PK of 
repeat oral doses of gepotidacin in adult female participants with clinical signs and 
symptoms of acute cystitis.

All participants who meet the study entry criteria and provide informed consent will 
receive oral gepotidacin 1500 mg BID for 5 days (total of 10 doses). 

Pretreatment and posttreatment PK collections will be performed throughout the 
study. Appropriate safety, efficacy, microbiological, and exploratory assessments will 
also be conducted throughout the study.

The study duration is approximately 28 days comprising approximately 5 days of 
confinement at the clinic followed by 2 outpatient visits as follows (see Table 1 and 
Section 9 for study visit details):

Clinic Confinement Visits
o
Baseline (Day -1 to Day 1 predose) Visit
o
On-Therapy (Day 1 to Day 5) Visit

Outpatient Visits
o
Test-of-Cure (TOC) (Day 10 to 13) Visit
o
Follow-up (Day 28) Visit

Participants will be confined to the clinic from Baseline through the On-Therapy
Visit. Participants will return to the clinic for the TOC and Follow-up Visits.
Note: At the discretion of the investigator, for emergency purposes only, participants 
may temporarily leave the clinic on study days without serial PK collections and only

at times that do not interfere with required study assessments. Participants will be 
instructed to follow the protocol restrictions. The investigator will ensure the 
participant is eligible to continue in the study upon return to the clinic. All doses of 
study treatment will be administered under site staff supervision in the clinic.

Participants with a concomitant fungal infection can only be treated with topical 
antifungals per local standard of care.

At any time during the study, participants experiencing new or continuing signs and 
symptoms of acute cystitis will be assessed and treated per the investigator’s 
judgement. If a participant is switched to a different antibiotic before or during the 
TOC Visit, all TOC procedures should be completed before the other antibiotic is 
started. Any participant who discontinues from the PK portion of the study should 
return for the TOC and Follow up-Visits.

5.4.
Scientific Rationale for Study Design
This Phase IIa study is designed primarily to evaluate plasma and urine pharmacokinetics
of gepotidacin in participants with acute cystitis. Serial sample collections will be 
performed on Day 1 (first dose) and on Day 4.
As this PK study will be conducted in female participants with acute cystitis, the 
exploratory clinical and microbiological efficacy of gepotidacin will also be assessed. 
The time points and success definitions were based on the Food and Drug Administration 
(FDA) guidance for industry for developing drug treatments for uncomplicated and 
complicated UTIs [DHHS, 1998; DHHS, 2015] and the European Medicines Agency 
(EMA) addendum to the guideline on the evaluation of medicinal products indicated for 
treatment of bacterial infections [EMA, 2013].
Efficacy will be assessed daily during the On-Therapy Visit, at TOC, and at Follow-up. 
Clinical success is defined as the resolution of signs and symptoms of acute cystitis 
present at Baseline (and no new signs and symptoms) and no use of other antimicrobial 
therapy. Microbiological success is defined as the reduction of the qualifying bacterial 
uropathogen (defined in Appendix 9) recovered at Baseline to <103 colony-forming 
units (CFU)/mL as observed on quantitative urine culture. Therapeutic success refers to 
participants who have been deemed both a microbiological success and a clinical success 
(i.e., responders).
Adult (≥18 to 65 years of age) eligible female participants will be enrolled in this 
open-label Phase IIa PK study. This age range was selected to minimize variability in 
systemic exposures as well as baseline uropathogens. This study in acute cystitis is 
restricted to female participants per the FDA guidance [DHHS, 1998]. As described in 
Section 5.5, the dose of gepotidacin and the 5-day duration were selected to provide 
efficacious treatment for acute cystitis and is in alignment with current clinical practice.

5.5.
Dose Justification
The oral gepotidacin dose in this study is 1500 mg BID (total daily dose of 3000 mg) for 
5 days. A 5-day dosing duration is in alignment with current treatment guidelines for 
efficacious antibacterial treatment of uncomplicated acute cystitis in women, which 
typically ranges from 3 to 7 days [Gupta, 2011b; GOV.UK, 2017; EAU, 2017]. The 
safety and tolerability at this oral dose and duration have been evaluated in Phase I 
studies and in a Phase II study (BTZ116704) (see Section 5 of the IB for details). 
Furthermore, high urine concentrations of gepotidacin are expected in this study based on 
a Phase I study (BTZ117351) where approximately 285 mg of unchanged gepotidacin 
was excreted in urine after a single, oral, 1500-mg (2 × 750-mg tablets) dose of 
gepotidacin.
The gepotidacin dose and duration for this Phase IIa PK uncomplicated UTI study were 
selected based on in vitro and in vivo studies including experimental animal 
pyelonephritis studies that simulated human PK exposures of gepotidacin to determine 
the efficacy of gepotidacin against isolates of E. coli, including MDR strains (see 
Section 4.2 of the IB for further details).
Additionally, preliminary data from a recently completed in vitro study to determine the 
PK/PD characteristics of gepotidacin against E. coli (dose-fractionation and dose-ranging 
studies) indicate that AUC/minimum inhibitory concentration (MIC) is the primary 
PK/PD index predictive of gepotidacin efficacy against E. coli. The magnitude of the 
ratio of the area under the free-drug concentration-time curve to MIC over 24 hours 
(fAUC/MIC) required to achieve net bacterial stasis as well as 1- and 2-log reductions in 
bacterial burden from baseline across multiple E. coli isolates with gepotidacin MIC 
values ranging from 1 to 4 g/mL, were 34.5, 41.3, and 49.7, respectively.
A set of duplicate 10-day hollow fiber infection model studies were also completed using 
E. coli isolate NCTC 13441 to determine the fAUC/MIC exposure of gepotidacin 
required to prevent the amplification of resistant subpopulation. An inverted-U shaped 
function described the relationship between drug resistance amplification and fAUC, with 
fAUC values ≥549 preventing resistance amplification to gepotidacin for E. coli in the 
hollow fiber infection model. This equates to an fAUC/MIC value ≥275 when applying 
the gepotidacin broth microdilution MIC of 2 g/mL for E. coli 13441, as determined in 
this study.
When taking the fAUC/MIC target of 275 for resistance supression into consideration 
with the concentrations of gepotidacin in human urine measured in a Phase I study 
(BTZ117351, minimum fAUC12h=807 µg.h/mL, so fAUC24h=1610 µg.h/mL) and, 
applying an MIC value of 4 g/mL, the minimum human urine fAUC/MIC achieved for 
the 1500 mg oral BID dose exceeds the fAUC/MIC resistance supression target of 275 by 
approximately 1.5-fold and 100% target attainment for an fAUC/MIC target of 275 
would be expected for participants with E. coli isolates with gepotidacin MICs ≤4 g/mL
following 1500 mg BID oral dosing.
In conclusion, minimum urine levels of gepotidacin are anticipated to be in excess of the 
fAUC/MIC target necessary for both efficacy and resistance suppression for E. coli as

determined from the in vitro PK/PD models. Given that the bladder is the primary site of 
infection in cystitis, the use of gepotidacin urine PK data, coupled with the robust in vivo
efficacy demonstrated in the human simulated PK pyelonephritis model, is appropriate 
for selecting the gepotidacin 1500 mg BID oral dose for 5 days for study in the treatment 
of participants with acute cystitis.

CONFIDENTIAL
206899
32

Protocol deviation

Termination of the study by GSK

Investigator discretion

Lack of efficacy
Note:  Pathogen identification or in vitro resistance of recovered uropathogens is not a 
reason for study treatment discontinuation.
The reason for study treatment discontinuation will be recorded in the electronic case
report form (eCRF). Participants who discontinue study treatment for the reasons above 
will not be considered withdrawn from the study and should attend the TOC and 
Follow-up Visits as applicable. 
If a participant discontinues during the on-treatment confinement period, Day 5 
assessments (Table 1) will be completed before the participant is discharged. The 
participant will be instructed to return for the TOC and Follow-up Visits.
8.1.1.
Liver Chemistry Stopping Criteria
Liver chemistry stopping and increased monitoring criteria have been designed to 
assure participant safety and evaluate liver event etiology.
Discontinuation of study treatment for abnormal liver tests is required when:

a participant meets one of the conditions outlined in Figure 2 and Figure 3.
OR

when in the presence of abnormal liver chemistries not meeting protocol-specified 
stopping rules, the investigator believes study treatment discontinuation is in the best 
interest of the participant.

8.1.2.
QTc Stopping Criteria
A participant who meets the following bulleted criteria based on the average of triplicate
ECG readings will be withdrawn from study treatment:

QTc >500 msec OR uncorrected QT >600 msec

Change from baseline of QTc >60 msec
For participants with underlying bundle-branch block, follow the discontinuation criteria 
listed below:
Baseline QTc with Bundle-Branch Block
Discontinuation QTc with Bundle-Branch 
Block
<450 msec
>500 msec
450 to 480 msec
≥530 msec

The same QT correction formula must be used for each individual participant to 
determine eligibility for and discontinuation from the study. This formula may not be 
changed or substituted once the participant has been enrolled.

For example, if a participant is eligible for the protocol based on QTcB, then 
QTcB must be used for discontinuation of this individual participant as well.

Once the QT correction formula has been chosen for a participant’s eligibility, the 
same formula must continue to be used for that participant for all QTc data being 
collected for data analysis. Safety ECGs and other non-protocol specified ECGs 
are an exception.

The QTc should be based on averaged QTc values of triplicate ECGs obtained over a 
brief (e.g., 5- to 10-minute) recording period.
See Table 1 for data to be collected at the time of treatment discontinuation and 
follow-up and for any further evaluations that need to be completed.
8.1.3.
Temporary Discontinuation
Temporary discontinuation of study treatment is not allowed. Participants who 
discontinue study treatment will not be considered withdrawn from the study and should 
attend the TOC and Follow-up Visits.
8.1.4.
Rechallenge
8.1.4.1.
Study Treatment Restart or Rechallenge
Study treatment restart or rechallenge after liver chemistry stopping criteria are met by 
any participant in this study is not allowed.

be withdrawn at any time at the discretion of the investigator for safety, behavioral, 
compliance, or administrative reasons.

Reasons for study withdrawal include:

Participant lost to follow-up

Participant withdrew consent

Termination of the study by GSK

Investigator discretion

If the participant withdraws consent for disclosure of future information, the sponsor 
may retain and continue to use any data collected before such a withdrawal of 
consent.

If a participant withdraws from the study, he/she may request destruction of any 
samples taken and not tested, and the investigator must document this in the site study 
records.

Refer to Table 1 for data to be collected at the time of study discontinuation and
follow-up and for any further evaluations that need to be completed.
8.3.
Lost to Follow-Up
A participant will be considered lost to follow-up if he or she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site. 
The following actions must be taken if a participant fails to return to the clinic for a 
required study visit:

The site must attempt to contact the participant and reschedule the missed visit as 
soon as possible and counsel the participant on the importance of maintaining the 
assigned visit schedule and ascertain whether or not the participant wishes to 
and/or should continue in the study.

Before a participant is deemed lost to follow-up, the investigator or designee must 
make every effort to regain contact with the participant (where possible, 
3 telephone calls and, if necessary, a certified letter to the participant’s last known 
mailing address or local equivalent methods). These contact attempts should be 
documented in the participant’s medical record.

Should the participant continue to be unreachable, he/she will be considered to 
have withdrawn from the study with a primary reason of lost to follow-up.

STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in Table 1 and Table 2. 

Protocol waivers or exemptions are not allowed.

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or 
discontinue study treatment.

Adherence to the study design requirements, including those specified in Table 1 and 
Table 2, is essential and required for study conduct.

All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening log 
to record details of all participants screened and to confirm eligibility or record 
reasons for screening failure, as applicable. 

Procedures conducted as part of the participant’s routine clinical management (e.g., 
blood count) and obtained before signing of ICF may be utilized for screening or 
baseline purposes provided the procedure met the protocol-specified criteria and was 
performed within the time frame defined in Table 1.

If assessments are scheduled for the same nominal time, THEN the assessments 
should occur in the following order:
1. 12-lead ECG
2. Vital signs
3. Pharmacokinetic and bacteriology urine specimen collection
4. Pharmacokinetic and safety blood draws
Note: The timing of the assessments should allow the blood draw to occur at the 
exact nominal time.

The maximum amount of blood collected from each participant over the duration of 
the study, including any extra assessments that may be required, will not exceed 
500 mL.

Repeat or unscheduled samples may be taken for safety reasons or for technical issues 
with the samples.

Participants will be confined to the clinic from Baseline through the On-Therapy 
Visit. Participants will return to the clinic for the TOC and Follow-up Visits.
Note: At the discretion of the investigator, for emergency purposes only, participants 
may temporarily leave the clinic on study days without serial PK collections and only 
at times that do not interfere with required study assessments. Participants will be
instructed to follow the protocol restrictions. The investigator will ensure the 
participant is eligible to continue in the study upon return to the clinic. All doses of 
study treatment will be administered under site staff supervision in the clinic.

The study will comprise the following visits and clinical procedures:
Clinic Confinement Visits

Baseline (Day -1 to Day 1 predose) Visit: The Baseline Visit includes a 
screening window of up to 24 hours from the time of informed consent to the first 
dose of study treatment. Baseline assessments performed during the screening 
window do not need to be repeated before study treatment is started unless 
indicated as a Day 1 predose assessment in Table 1. 
Baseline assessments will be performed, including the following (see Table 1):
o
Participants will provide a pretreatment clean-catch midstream urine 
sample for confirmation of pyuria (≥10 WBC/mm3 or the presence of 
leukocyte esterase) and/or nitrite per local laboratory procedures.
Note: Repeat baseline urine samples are allowed if contamination, defined 
as ≥10 squamous epithelial cells, is observed under microscopic 
evaluation. 
o
Site staff will record clinical signs and symptoms of acute cystitis
(Appendix 10), clinical laboratory samples will be collected, vital signs 
will be measured, and a triplicate 12-lead ECG and complete physical 
examination will be performed. 
o
Participants who meet the eligibility criteria in time to support the first 
dose of study treatment by 2 PM will be admitted to the clinic on Day 1 
and On-Therapy procedures will begin. Participants who meet the 
eligibility criteria past the first dose time limit of 2 PM may be admitted 
that same day (Day -1) or the next morning (Day 1); dosing will start on 
the morning of Day 1.
Day 1 predose assessments will be performed (see Table 1 and Table 2), including 
the following:
o
An ECG will be performed and vital signs will be measured if the baseline 
assessment was not within 4 hours of the first dose of study treatment.
o
Participants will provide a pretreatment clean-catch midstream urine 
sample for Gram stain, quantitative bacteriology culture, and antimicrobial 
susceptibility testing.
o
Predose blood and urine PK samples will be collected.
o
A stool microbiome specimen will be obtained from participants who 
consent to provide such specimens.
o
Vaginal and pharyngeal swab microbiome specimens will be obtained 
from participants who consent to provide such specimens.

On-Therapy (Day 1 to Day 5) Visit: Participants will be confined to the clinic 
during the 5-day On-Therapy Visit period, and will receive oral gepotidacin 
1500 mg BID for 5 days (total of 10 doses) starting with the first dose on Day 1.

all doses will be administered with food (i.e., standardized meals or snacks as 
applicable).
o
The first dose of gepotidacin must be administered by 2 PM on Day 1 and 
subsequent doses will be administered approximately every 12 hours.
o
Only if medically appropriate per the investigator’s judgement, for 
participants who are enrolled after 2 PM, the first dose of study treatment 
will be postponed until the next morning; nonexclusionary pain 
medication will be allowed for these participants before study treatment is 
started.
o
Study assessments and PK collections on Days 1 through 5 will be 
performed relative to the time-matched dose as determined by the first 
dose of study treatment (e.g., if the first dose is at 11 AM on Day 1 for a 
participant, then their time-matched dose on subsequent days will be at 
11 AM; or, if the first dose is at 1 PM on Day 1 for a participant, then their 
time-matched dose on subsequent days will be at 1 PM). 
o
On Day 1, a single 12-lead ECG will be performed at 2 hours after the first 
dose of study treatment. On Day 4, a single 12-lead ECG will be 
performed at predose and 2 hours postdose (at the same ECG time points 
as on Day 1) (see Table 2).
o
Vital sign measurements will be taken daily from Days 2 through 5.
o
On Days 2 through 5, before the time-matched dose, clinical signs and 
symptoms of acute cystitis will be recorded (Appendix 10) and 
participants will provide a clean-catch midstream urine sample for Gram 
stain, quantitative bacteriology culture, and antimicrobial susceptibility 
testing.
o
Blood and urine PK collection (see Table 1, Table 2, and Section 9.5.1).
o
On Day 3, clinical laboratory samples will be collected for hematology, 
chemistry, and urinalysis.
o
On Day 4, at predose and at approximately 2 hours postdose, cervical, 
rectal, and pharyngeal swab PK specimens will be obtained from 
participants who consent to provide such specimens.
o
On Day 5, a stool microbiome specimen will be obtained from participants 
who consent to provide such specimens. 
o
On Day 5, vaginal and pharyngeal swab microbiome specimens will be 
obtained from participants who consent to provide such specimens.
o
On Day 5, after all study procedures have been performed, including a 
predose clean-catch midstream urine sample for Gram stain, quantitative 
bacteriology culture, and antimicrobial susceptibility testing, predose PK 
sample collections, and safety assessments, participants will be discharged 
from the clinic. Participants should remain in the clinic to complete a total 
of 10 doses. Participants will be instructed to return for the TOC (Day 10

At any time during the study, participants experiencing new or continuing 
signs and symptoms of acute cystitis will be assessed and treated per the 
investigator’s judgement. If a participant is switched to a different 
antibiotic before or during the TOC Visit, all TOC procedures should be 
completed before the other antibiotic is started. Any participant who 
discontinues from the PK portion of the study should return for the TOC 
and Follow-up Visits.
Outpatient Visits

TOC (Day 10 to 13) Visit: Participants will return for the TOC Visit 5 to 8 days 
after completion of study treatment. Clinical signs and symptoms of acute cystitis 
will be recorded (Appendix 10) and samples for Gram stain, quantitative 
bacteriology culture, and antimicrobial susceptibility testing will be collected. 
Safety assessments will be performed and AEs and concomitant medication use 
will be recorded.

Follow-up (Day 28) Visit: Participants will return for the Follow-up Visit 
28 (±3) days after the start of study treatment. Clinical signs and symptoms of 
acute cystitis will be recorded (Appendix 10) and samples for Gram stain, 
quantitative bacteriology culture, and antimicrobial susceptibility testing will be 
collected. Adverse events and concomitant medication use will be recorded. A 
stool microbiome specimen will be obtained from participants who consent to 
provide such specimens. Vaginal and pharyngeal swab microbiome specimens
will be obtained from participants who consent to provide such specimens.
9.1.
Efficacy Assessments
Efficacy is an exploratory assessment in this study. Please refer to Section 9.5 for the 
primary PK assessments. 
9.1.1.
Therapeutic Response Evaluation
Therapeutic response (success/failure) is a measure of the overall efficacy response. A
therapeutic success refers to participants who have been deemed both a “microbiological 
success” (see Section 9.1.2.1) and a “clinical success” (i.e., “responders”) (see 
Section 9.1.3). All other combinations (other than clinical success + microbiological 
success) will be deemed failures for therapeutic response. 
Therapeutic response will be determined by statistical programming for TOC and 
Follow-up Visits.
9.1.2.
Bacteriology Samples
At the Baseline Visit (predose on Day 1), a pretreatment, clean-catch midstream urine 
sample must be obtained from all participants for Gram stain, quantitative bacteriological 
culture, and in vitro antimicrobial susceptibility testing. For inclusion in the micro-ITT 
Population (Section 10.2), a baseline qualifying bacterial uropathogen (defined in 
Appendix 9) is required. At the On-Therapy (Days 2 through 5 only), TOC, and 
Follow-up Visits, a clean-catch midstream urine sample will be obtained and sent to a

central laboratory for Gram stain, quantitative bacteriological culture, and in vitro 
antimicrobial susceptibility testing. Identification and susceptibility testing of isolates 
recovered from urine specimens at all visits will also be conducted at a designated 
laboratory. Additional tests, as needed, to further characterize recovered isolates will also 
be performed by a designated laboratory. Instructions for sample collection, processing, 
and shipment are provided in the SRM and the laboratory manual. The study site should 
follow the Microbiology Procedures section of the laboratory manual to minimize 
potential contamination of the specimens.
9.1.2.1.
Microbiological Outcome and Response
Only those participants who have a qualifying bacterial uropathogen (defined in 
Appendix 9) identified at Baseline will be evaluated for microbiological outcome and 
response. The microbiological outcome and response to study treatment will be 
determined by prespecified programmed algorithm for each participant/pathogen.
The microbiological outcome is determined by comparing the baseline culture results to 
the culture results at each subsequent visit (see Table 3, Table 4, and Table 5). The 
corresponding microbiological response (success or failure) “by pathogen” is then 
assigned, as shown in Table 4 and Table 5. Participant level microbiological response is a 
measure of the combined “by pathogen” response(s). Participant level microbiological 
success refers to participants who have been deemed a “microbiological success” for all 
of their “by pathogen” microbiological responses. All other combinations (other than all 
“microbiological successes”) are deemed failures for participant level microbiological 
response. Participant level microbiological response will be determined by statistical 
programming.

Clinical Evaluation
Clinical signs and symptoms of acute cystitis will be recorded by site staff based on 
participant interview per the Schedule of Activities table (Table 1) using the scoring 
system in Appendix 10. At Baseline, the participant must present with at least 2 signs and 
symptoms and have a total cumulative symptom score ≥2. At TOC, success is recorded as 
normal presentation of signs and symptoms with a total cumulative symptom score of 
zero and no new signs and symptoms of the infection under study.
The investigator will determine the clinical outcome by comparing the signs and 
symptoms of acute cystitis at the On-Therapy (Days 2 through 5 only), TOC, and 
Follow-up Visits to those present at Baseline. Clinical response (success or failure) will 
be determined at the TOC and Follow-up Visits, as summarized in Table 6. Clinical 
success at the On-Therapy (Days 2 through 5 only), TOC, and Follow-up Visits is 
defined as resolution of signs and symptoms of acute cystitis present at Baseline (and no 
new signs and symptoms) and no use of other antimicrobial therapy. For participants who

a.
The investigator will determine the clinical outcome by comparing the signs and symptoms of acute cystitis at the 
On-Therapy (Days 2 through 5 only), TOC, and Follow-up Visits) to those present at Baseline.
b.
A participant showing some improvement at the On-Therapy Visit (Days 2 through 5 only) but less than what 
would be considered a clinical success should remain on study treatment per protocol, but study treatment may 
be discontinued per predefined criteria (see Section 8.1) or if there has been no clinical improvement; study 
treatment may be replaced by a different antibiotic, at the discretion of the investigator.
9.2.
Adverse Events
The definitions of an AE or SAE can be found in Appendix 4.
The investigator and any designees are responsible for detecting, documenting, and 
reporting events that meet the definition of an AE or SAE and remain responsible for 
following up AEs that are serious, considered related to the study treatment or the study,
or that caused the participant to discontinue the study treatment or from the study (see 
Section 8). 
9.2.1.
Time Period and Frequency for Collecting AE and SAE 
Information

All SAEs will be collected from the signing of the ICF until the Follow-up Visit
at the time points specified in Table 1.

All AEs will be collected from the start of treatment until the Follow-up Visit at 
the time points specified in Table 1.

Medical occurrences that begin before the start of study treatment but after 
obtaining informed consent will be recorded on the Medical History/Current 
Medical Conditions section of the eCRF not the AE section.
 
2018N388745_00


2017N317982_00
CONFIDENTIAL
206899
46

All SAEs will be recorded and reported to the sponsor or designee immediately 
and under no circumstance should this exceed 24 hours, as indicated in 
Appendix 4. The investigator will submit any updated SAE data to the sponsor 
within 24 hours of it being available.

Investigators are not obligated to actively seek AEs or SAEs in former study 
participants. However, if the investigator learns of any SAE, including a death, at 
any time after a participant has been discharged from the study, and he/she 
considers the event to be reasonably related to the study treatment or study 
participation, the investigator must promptly notify the sponsor.

The method of recording, evaluating, and assessing causality of AEs and SAEs
and the procedures for completing and transmitting SAE reports are provided in
Appendix 4.
9.2.2.
Method of Detecting AEs and SAEs
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended 
and nonleading verbal questioning of the participant is the preferred method to inquire 
about AE occurrence. 
9.2.3.
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
participant at subsequent visits/contacts. All SAEs and nonserious AEs of special interest 
(as defined in Section 9.2.5), will be followed until the event is resolved, stabilized, 
otherwise explained, or the participant is lost to follow-up (as defined in Section 8.3). 
Further information on follow-up procedures is given in Appendix 4.
9.2.4.
Regulatory Reporting Requirements for SAEs

Prompt notification by the investigator to the sponsor of an SAE is essential so 
that legal obligations and ethical responsibilities towards the safety of participants 
and the safety of a study treatment under clinical investigation are met. 

The sponsor has a legal responsibility to notify both the local regulatory authority 
and other regulatory agencies about the safety of a study treatment under clinical 
investigation. The sponsor will comply with country-specific regulatory 
requirements relating to safety reporting to the regulatory authority, institutional 
review board (IRB), and investigators.

Investigator safety reports must be prepared for suspected unexpected serious 
adverse reactions according to local regulatory requirements and sponsor policy 
and forwarded to investigators as necessary.

An investigator who receives an investigator safety report describing an SAE or 
other specific safety information (e.g., summary or listing of SAEs) from the 
sponsor will review and then file it along with the IB and will notify the IRB, if 
appropriate according to local requirements.

9.2.5.
Adverse Events of Special Interest
Predefined AEs of special interest for this study are cardiovascular (CV) events and 
gastrointestinal events (see Section 3.3.1), which will be identified by a prespecified list 
of coded terms.
9.2.6.
Cardiovascular and Death Events
For any cardiovascular events detailed in Appendix 4 and all deaths, whether or not they 
are considered SAEs, specific Cardiovascular and Death sections of the eCRF will be 
required to be completed. These sections include questions regarding CV (including 
sudden cardiac death) and non-CV death. 
The CV CRFs are presented as queries in response to reporting of certain CV Medical 
Dictionary for Regulatory Activities (MedDRA) terms. The CV information should be 
recorded in the specific CV section of the eCRF within 1 week of receipt of a CV Event 
data query prompting its completion. 
The Death eCRF is provided immediately after the occurrence or outcome of death is 
reported. Initial and follow-up reports regarding death must be completed within 1 week 
of when the death is reported.
9.2.7.
Pregnancy

Details of all pregnancies in female participants will be collected after the start of 
study treatment and through the Follow-up Visit.

If a pregnancy is reported, the investigator should inform GSK/PPD within 24 hours 
of learning of the pregnancy and should follow the procedures outlined in 
Appendix 6.

Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAEs.
9.3.
Treatment of Overdose
There is no specific antidote for overdose with a bacterial topoisomerase inhibitor. In the 
event of a suspected overdose, it is recommended that the appropriate supportive clinical 
care should be instituted, as dictated by the participant’s clinical status.
In the event of an overdose, the investigator should:
1. Contact the medical monitor immediately.
2. Closely monitor the participant for AEs/SAEs and laboratory abnormalities until 
study treatment can no longer be detected systemically (at least 72 hours).
3. Obtain a plasma sample for PK analysis within 24 hours from the date of the last dose 
of study treatment if requested by the medical monitor (determined on a case-by-case 
basis).

4. Document the quantity of the excess dose as well as the duration of the overdosing in 
the eCRF.
Decisions regarding dose interruptions or modifications will be made by the investigator 
in consultation with the medical monitor based on the clinical evaluation of the 
participant.
9.4.
Safety Assessments
Planned time points for all safety assessments are provided in Table 1.
9.4.1.
Physical Examinations

Physical examinations will be performed at the time points indicated in Table 1.


Vital signs will be measured at the time points indicated in Table 1.

Vital signs will be measured in a semi-supine position and will include 
temperature, systolic and diastolic blood pressure, and pulse rate.

Vital sign measurements should be preceded by at least 5 minutes of rest for the 
participant in a quiet setting without distractions (e.g., television, cell phones).

Blood pressure and pulse measurements will be assessed with a completely 
automated device. Manual techniques will be used only if an automated device is 
not available.

Vital sign measurements should be obtained before any blood draws scheduled on 
the same assessment day.

Clinically significant changes from baseline will be reported as AEs.
9.4.3.

that may be necessary.
9.4.4.
Clinical Safety Laboratory Assessments

Refer to Appendix 2 for the list of clinical laboratory tests to be performed and to 
Table 1 for the timing and frequency. 

The investigator must review the laboratory report, document this review, and 
record any clinically relevant changes occurring during the study in the AE 
section of the eCRF. The laboratory reports must be filed with the source 
documents. Clinically significant abnormal laboratory findings are those which 
are not associated with the underlying disease, unless judged by the investigator 
to be more severe than expected for the participant’s condition.

All laboratory tests with values considered clinically significantly abnormal 
during participation in the study should be repeated until the values return to 
normal or baseline or are no longer considered significantly abnormal by the 
investigator or medical monitor. 

If such values do not return to normal/baseline within a period of time judged 
reasonable by the investigator, the etiology should be identified and the sponsor 
notified.

All protocol-required laboratory assessments, as defined in Appendix 2, must be 
conducted in accordance with the laboratory manual and Table 1.
9.5.

STATISTICAL CONSIDERATIONS
Full details of all data handling conventions and statistical analyses conducted for this 
study will be provided in the reporting and analysis plan (RAP).
Hypothesis
A formal hypothesis will not be tested; however, an estimation approach will be taken to 
characterize the PK of gepotidacin in female participants with uncomplicated UTI.
10.1.
Sample Size Determination
The target sample size is approximately 20 participants who complete the study 
assessments through Day 5. The sample size for this study was based on feasibility; 
however, justification has been considered. Gepotidacin 1500 mg BID PK parameter 
estimates are available from a healthy volunteer study with repeat dosing for 14 days. For 
this dose of gepotidacin, the coefficient of variations for AUC(0-) and Cmax were 
21.9% and 40.3%, respectively, after the initial dose, and 29.6% and 31.1%, respectively,
at steady state. The upper limit of the 95% confidence interval for the mean of the PK 
parameters on both Days 1 and 4 for AUC(0-) and Cmax will be approximately within 
15% and 20%, respectively, above the point estimate of the corresponding PK parameter.

Population
Description
PK Population
Participants who receive at least 1 dose of gepotidacin and have 
evaluable plasma, urine, or tissue concentration data for 
gepotidacin. This primary analysis population will be used in the 
assessment and characterization of PK concentrations 
(summary tables and figures).
PK Parameter Population
All participants in the PK Population who received gepotidacin 
1500 mg BID through the completion of all PK collections for 
whom valid and evaluable plasma or urine PK parameters are 
derived for gepotidacin. This primary analysis population will be 
used in the assessment and characterization of PK parameters
(summary and analysis tables and figures).

completion. A study site is considered closed when all required documents and study 
supplies have been collected and a study-site closure visit has been performed.
The investigator may initiate study-site closure at any time, provided there is reasonable 
cause and sufficient notice is given in advance of the intended termination.
Reasons for the early closure of a study site by the sponsor or investigator may include 
but are not limited to:

Failure of the investigator to comply with the protocol, the requirements of the IRB or 
local health authorities, the sponsor’s procedures, or GCP guidelines

Inadequate recruitment of participants by the investigator

Discontinuation of further study treatment development

Appendix 4: Adverse Events: Definitions and Procedures for 
Recording, Evaluating, Follow-up, and Reporting
Definition of AE
AE Definition

An AE 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.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a study treatment.
Events Meeting the AE Definition 

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
other safety assessments (e.g., ECG, radiological scans, vital signs measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator (i.e., not related to progression of 
underlying disease).

Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition.

New conditions detected or diagnosed after study treatment administration even 
though it may have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
treatment or a concomitant medication. Overdose per se will not be reported as an 
AE/SAE unless it is an intentional overdose taken with possible suicidal/self-harming 
intent. Such overdoses should be reported regardless of sequelae.

“Lack of efficacy” or “failure of expected pharmacological action” per se will not be 
reported as an AE or SAE. Such instances will be captured in the efficacy 
assessments. However, the signs, symptoms, and/or clinical sequelae resulting from 
lack of efficacy will be reported as AE or SAE if they fulfill the definition of an AE 
or SAE. 
Events NOT Meeting the AE Definition 

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition.

The disease/disorder being studied or expected progression, signs, or symptoms of the 
disease/disorder being studied, unless more severe than expected for the participant’s 
 
2018N388745_00

68
condition.

Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 
leads to the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen.
Definition of SAE
If an event is not an AE per definition above, then it cannot be an SAE even if serious 
conditions are met (e.g., hospitalization for signs/symptoms of the disease under study, 
death due to progression of disease).
An SAE is defined as any untoward medical occurrence that, at any dose:
a.
Results in death
b.
Is life-threatening
The term “life-threatening” in the definition of “serious” refers to an event in which the 
participant was at risk of death at the time of the event. It does not refer to an event, 
which hypothetically might have caused death, if it were more severe.
c.
Requires inpatient hospitalization or prolongation of existing hospitalization
In general, hospitalization signifies that the participant has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for observation 
and/or treatment that would not have been appropriate in the physician’s office or 
outpatient setting. Complications that occur during hospitalization are AE. If a 
complication prolongs hospitalization or fulfills any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalization” occurred or was necessary, the AE 
should be considered serious.
Hospitalization for elective treatment of a pre-existing condition that did not worsen from 
baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (e.g., sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption.
e.
Is a congenital anomaly/birth defect

69
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that may 
not be immediately life-threatening or result in death or hospitalization but may 
jeopardize the participant or may require medical or surgical intervention to prevent 
one of the other outcomes listed in the above definition. These events should usually 
be considered serious.
Examples of such events include invasive or malignant cancers, intensive treatment in 
an emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency 
or drug abuse.
Definition of Cardiovascular Events
Cardiovascular Events (CV) Definition:
Investigators will be required to fill out the specific CV event page of the CRF for the 
following AEs and SAEs:

Myocardial infarction/unstable angina

Congestive heart failure

Arrhythmias

Valvulopathy

Pulmonary hypertension

Cerebrovascular events/stroke and transient ischemic attack

Peripheral arterial thromboembolism

Deep venous thrombosis/pulmonary embolism

Revascularization

Recording AE and SAE
AE and SAE Recording

When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g., hospital progress notes, laboratory, and diagnostics reports) 
related to the event.

The investigator will then record all relevant AE/SAE information in the CRF.

It is not acceptable for the investigator to send photocopies of the participant’s 
medical records to GSK in lieu of completion of the GSK /AE/SAE CRF page.

There may be instances when copies of medical records for certain cases are 
requested by GSK. In this case, all participant identifiers, with the exception of the 
participant number, will be redacted on the copies of the medical records before 
submission to GSK.

The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis (not 
the individual signs/symptoms) will be documented as the AE/SAE.
Assessment of Intensity

The severity of AEs and SAEs will be determined by the investigator according to the 
US National Institute of Allergy and Infectious Diseases Division of Microbiology 
and Infectious Diseases criteria for adult toxicity assessment [DMID, 2007] and 
(Appendix 5).
An event is defined as ‘serious’ when it meets at least 1 of the predefined outcomes as 
described in the definition of an SAE, NOT when it is rated as severe.
Assessment of Causality

The investigator is obligated to assess the relationship between study treatment and 
each occurrence of each AE/SAE.

A "reasonable possibility" of a relationship conveys that there are facts, evidence, 
and/or arguments to suggest a causal relationship, rather than a relationship cannot be 
ruled out.

The investigator will use clinical judgment to determine the relationship.

Alternative causes, such as underlying disease(s), concomitant therapy, and other risk 
factors, as well as the temporal relationship of the event to study treatment 
administration will be considered and investigated.

The investigator will also consult the investigator’s brochure (IB) and/or Product 
Information, for marketed products, in his/her assessment.

For each AE/SAE, the investigator must document in the medical notes that he/she 
has reviewed the AE/SAE and has provided an assessment of causality.

There may be situations in which an SAE has occurred and the investigator has 
 
2018N388745_00


2017N317982_00
CONFIDENTIAL
206899
71
minimal information to include in the initial report to GSK. However, it is very 
important that the investigator always make an assessment of causality for every 
event before the initial transmission of the SAE data to GSK.

The investigator may change his/her opinion of causality in light of follow-up 
information and send an SAE follow-up report with the updated causality assessment.

The causality assessment is one of the criteria used when determining regulatory 
reporting requirements.
Follow-up of AE and SAE

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by GSK to 
elucidate the nature and/or causality of the AE or SAE as fully as possible. This may 
include additional laboratory tests or investigations, histopathological examinations, 
or consultation with other health care professionals.

If a participant dies during participation in the study or during a recognized follow-up 
period, the investigator will provide GSK with a copy of any post-mortem findings 
including histopathology.

New or updated information will be recorded in the originally completed CRF.

The investigator will submit any updated SAE data to GSK within 24 hours of receipt 
of the information.
Reporting of SAE to GSK
SAE Reporting to GSK via Electronic Data Collection Tool

The primary mechanism for reporting SAE to GSK will be the electronic data 
collection tool.

If the electronic system is unavailable, then the site will use the paper SAE data 
collection tool (see next section) in order to report the event within 24 hours.

The site will enter the SAE data into the electronic system as soon as it becomes 
available.

The investigator or medically-qualified sub-investigator must show evidence within 
the eCRF (e.g., check review box, signature, etc.) of review and verification of the 
relationship of each SAE to IP/study participation (causality) within 72 hours of SAE 
entry into the eCRF.

After the study is completed at a given site, the electronic data collection tool will be 
taken off-line to prevent the entry of new data or changes to existing data.

If a site receives a report of a new SAE from a study participant or receives updated 
data on a previously reported SAE after the electronic data collection tool has been 
taken off-line, then the study site can report this information to the medical monitor 
or SAE coordinator by telephone.

Contacts for SAE reporting can be found in SRM.

Appendix 5: Division of Microbiology and Infectious 
Diseases Adult Toxicity Tables for Adverse Event 
Assessment
ESTIMATING SEVERITY GRADE: For abnormalities NOT found elsewhere in the 
Toxicity Tables, use the scale below to estimate grade of severity:
GRADE 1
Mild
Transient or mild discomfort (<48 hours); no medical 
intervention/therapy required
GRADE 2
Moderate
Mild to moderate limitation in activity – some assistance 
may be needed; no or minimal medical 
intervention/therapy required
GRADE 3
Severe
Marked limitation in activity, some assistance usually 
required; medical intervention/therapy required, 
hospitalizations possible
GRADE 4
Life-threatening
Extreme limitation in activity, significant assistance 
required; significant medical intervention/therapy required, 
hospitalization or hospice care probable
SERIOUS OR LIFE-THREATENING AEs: ANY clinical event deemed by the 
investigator to be serious or life-threatening should be considered a grade 4 event. 
Clinical events considered to be serious or life-threatening include, but are not limited to: 
seizures, coma, tetany, diabetic ketoacidosis, disseminated intravascular coagulation, 
diffuse petechiae, paralysis, acute psychosis, and severe depression.
COMMENTS REGARDING THE USE OF THESE TABLES

Standardized and commonly used toxicity tables (Division of AIDS, National Cancer 
Institute’s Common Toxicity Criteria, and World Health Organization) have been 
adapted for use by the Division of Microbiology and Infectious Diseases (DAIDS) 
and modified to better meet the needs of participants in Division of Microbiology and 
Infectious Diseases (DMID) trials.

For parameters not included in the following Toxicity Tables, study sites should refer 
to the “Guide for Estimating Severity Grade” located above.

Criteria are generally grouped by body system.
Some protocols may have additional protocol specific grading criteria, which will 
supersede the use of these tables for specified criteria.

Appendix 6: Contraceptive Guidance and Collection of 
Pregnancy Information
Definitions
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming post-menopausal 
unless permanently sterile (see below)
Women in the following categories are not considered WOCBP
1. Premenarchal
2. Premenopausal female with ONE of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy
Note:  Documentation can come from the site personnel’s: review of participant’s 
medical records, medical examination, or medical history interview.
3. Postmenopausal female

A postmenopausal state is defined as no menses for 12 months without an 
alternative medical cause. A high follicle stimulating hormone (FSH) level in the 
postmenopausal range may be used to confirm a postmenopausal state in women 
not using hormonal contraception or hormonal replacement therapy (HRT). 
However, in the absence of 12 months of amenorrhea, a single FSH measurement 
is insufficient. 

Females on HRT and whose menopausal status is in doubt will be required to use 
one of the non-hormonal highly effective contraception methods if they wish to 
continue their HRT during the study. Otherwise, they must discontinue HRT to 
allow confirmation of postmenopausal status before study enrollment.
Contraception Guidance
Female participants
Female participants of childbearing potential are eligible to participate if they agree to 
use a highly effective method of contraception consistently and correctly as described in 
Table 8 in addition to using a male condom during intercourse.

ovulationb

Intrauterine device (IUD)

Intrauterine hormone-releasing system (IUS)

bilateral tubal occlusion
Vasectomized partner 
(A vasectomized partner is a highly effective contraception method provided that the partner is 
the sole male sexual partner of the WOCBP and the absence of sperm has been confirmed. If 
not, an additional highly effective method of contraception should be used.)
Sexual abstinence 
(Sexual abstinence is considered a highly effective method only if defined as refraining from 
heterosexual intercourse during the entire period of risk associated with the study drug. The 
reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and 
the preferred and usual lifestyle of the participant.)
WOCBP=woman of childbearing potential.
a.
Typical use failure rates may differ from those when used consistently and correctly. Use should be consistent 
with local regulations regarding the use of contraceptive methods for participants in clinical studies. 
b.
Hormonal contraception may be susceptible to interaction with the study drug, which may reduce the efficacy of 
the contraceptive method. In this case 2 highly effective methods of contraception should be utilized during the 
treatment period and through the Test-of-Cure (Day 10 to 13) Visit.

Pregnancy Testing

WOCBP should only be included after a confirmed menstrual period and a negative 
highly sensitive urine pregnancy test 

Additional pregnancy testing will be performed on Day 5 and at the Test-of-Cure 
(Day 10 to 13) Visit, 5 to 8 days after the last dose of study treatment and as required 
locally 

Pregnancy testing will be performed whenever a menstrual cycle is missed or when 
pregnancy is otherwise suspected 

Pregnancy testing, with a sensitivity of 25 mIU/mL, will be performed using the test 
kit provided by the designated laboratory
Collection of Pregnancy Information
Female Participants who become pregnant

Investigator will collect pregnancy information on any female participant, who 
becomes pregnant while participating in this study. 

Information will be recorded on the appropriate form and submitted to 
GlaxoSmithKline (GSK)/PPD within 24 hours of learning of a participant’s 
pregnancy. 

Participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow up information on participant and neonate, which will 
be forwarded to GSK. Generally, follow-up will not be required for longer than 6 to 
8 weeks beyond the estimated delivery date. 

Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for procedure. 

While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy will be reported as an AE or 
SAE. 

A spontaneous abortion is always considered to be an SAE and will be reported as 
such. 

Any SAE occurring as a result of a post-study pregnancy which is considered 
reasonably related to the study treatment by the investigator, will be reported to GSK
as described in Appendix 4. While the investigator is not obligated to actively seek 
this information in former study participants, he or she may learn of an SAE through 
spontaneous reporting. 

Any female participant who becomes pregnant while participating will discontinue 
study treatment.

Appendix 7: Genetics
USE/ANALYSIS OF DNA

Genetic variation may impact a participant’s response to therapy, susceptibility, 
severity, and progression of disease. Variable response to therapy may be due to 
genetic determinants that impact drug absorption, distribution, metabolism, and 
excretion; mechanism of action of the drug; disease etiology; and/or molecular 
subtype of the disease being treated. Therefore, where local regulations and 
institutional review board allow, a blood sample will be collected for DNA analysis.

DNA samples will be used for research related to gepotidacin or uncomplicated 
urinary tract infections and related diseases. They may also be used to develop 
tests/assays including diagnostic tests) related to and uncomplicated urinary tract 
infections. Genetic research may consist of the analysis of 1 or more candidate genes 
or the analysis of genetic markers throughout the genome [or analysis of the entire 
genome] (as appropriate)

DNA samples will be analyzed if it is hypothesized that this may help further 
understand the clinical data. 

The samples may be analyzed as part of a multi-study assessment of genetic factors 
involved in the response to gepotidacin or study treatments of this class. The results 
of genetic analyses may be reported in the clinical study report or in a separate study
summary.

The sponsor will store the DNA samples in a secure storage space with adequate 
measures to protect confidentiality. 

The samples will be retained while research on gepotidacin (or study treatments of 
this class) or uncomplicated urinary tract infections continues but no longer than 
15 years after the last participant last visit or other period as per local requirements.

INTRODUCTION
The purpose of this reporting and analysis plan (RAP) is to describe the analyses to be 
included in the Clinical Study Report for Protocol: 206899.
2.
SUMMARY OF KEY PROTOCOL INFORMATION
This Phase IIa study is designed primarily to evaluate plasma and urine pharmacokinetics 
(PK) of gepotidacin in female participants with clinical signs and symptoms of acute 
cystitis. As this PK study will be conducted in female participants with clinical signs and 
symptoms of acute cystitis, exploratory clinical and microbiological efficacy of 
gepotidacin will also be assessed.
2.1.
Changes to the Protocol Defined Statistical Analysis Plan
Changes from the originally planned statistical analysis specified in the protocol are 
outlined in Table 1.
Table 1
Changes to Protocol Defined Analysis Plan
Protocol
Reporting & Analysis Plan
Statistical Analysis Plan
Statistical Analysis Plan
Rationale for Changes

Clinical outcome will be 
determined by the 
investigator

In addition to 
investigator-determined clinical 
outcome, a sponsor-determined 
clinical outcome will be 
programmatically derived

To solve the potential dilemma 
that a participant with record 
missing or unable-to-determine 
at Test-of-Cure (TOC) visit but 
free of signs and symptoms of 
acute cystitis at Follow-up Visit 
will likely be determined as 
“clinical success” by the 
investigator but falls under 
failure per US Food and Drug 
Administration (FDA) guidance
[DHHS, May 2018; DHHS, 
June 2018].

Clinical outcome will be 
determined at the On-
Therapy (Days 2 
through 5), TOC, and 
Follow-up visits by 
comparing the signs 
and symptoms of acute 
cystitis to those 
present at Baseline. 
Clinical response 
(success or failure) will 
be determined at the 
TOC and Follow-Up 
visits

In addition, clinical cure, a binary 
result of ‘Yes’ or ‘No’ will be 
determined at the On-Therapy 
(Days 2 through 5), TOC, and 
Follow-Up visits. Clinical cure is 
defined as complete resolution of
signs and symptoms of acute 
cystitis present at Baseline, with 
no new signs and symptoms, and 
no use of other antimicrobial 
therapy. Clinical cure at Follow-up 
visit must also meet clinical cure 
at TOC in addition to above 
criteria

To apply a clinical criterion that 
is consistently focusing on 
complete resolution of clinical 
signs and symptoms through 
On-Therapy, TOC, and Follow-
Up visits.

Study Treatment & Sub-group Display Descriptors
Only one treatment, oral gepotidacin 1500 mg BID will be administered in this study as 
the study treatment.
5.2.
Baseline Definitions
For all endpoints (except as noted in baseline definitions) the baseline value will be the 
latest predose assessment with a non-missing value, including those from unscheduled 
visits. If time is not collected, Day 1 assessments are assumed to be taken prior to first 
dose and used as baseline.

assessments will be used as baseline in data display. Average of the triplicate ECG assessment at Day -1 will 
be used as the baseline if Day 1 predose assessment is not performed as described in Appendix 4: Derived and 
Transformed Data.
Unless otherwise stated, if baseline data is missing no derivation will be performed and 
baseline will be set to missing.

7.1.1.
Endpoint / Variables
7.1.1.1.
Drug Concentration Measures
Refer to Appendix 3: Data Display Standards & Handling Conventions (Section 12.3.3
Reporting Standards for Pharmacokinetic). Only total gepotidacin plasma PK 
concentrations will be measured and reported in the bioanalytical data. Therefore, 
unbound plasma PK concentrations will be derived by multiplying the total plasma PK 
concentrations by 0.67, to correct for the low plasma protein binding of gepotidacin 
(33%) observed in previous studies.
7.1.1.2.
Derived Pharmacokinetic Parameters
Pharmacokinetic parameters will be calculated by standard non-compartmental analysis 
according to current working practices and using the currently supported version of 
Phoenix WinNonlin version 6.4 or higher. All calculations of non-compartmental 
parameters will be based on actual sampling times. Pharmacokinetic parameters listed 
will be determined from the plasma and urine concentration-time data, as data permits.
Table 2 provides the details of derived plasma PK parameters.

9.1.1.1.
Microbiological Outcome and Response

The microbiological outcome and response to study treatment will be determined by 
prespecified programmed algorithm for each participant/qualifying uropathogen.

The microbiological outcome is determined by comparing the baseline culture results 
to the culture results at each subsequent visit. The corresponding microbiological 
response “by qualifying uropathogen” is then assigned. The criteria of 
microbiological outcome and response are shown in Table 4, Table 5, and Table 6.

Participant level microbiological success refers to participants who have been deemed 
a “microbiological success” for all their “qualifying baseline uropathogen” 
microbiological responses.

All other combinations are deemed failures for participant level microbiological 
response.

Participants who withdraw from the study prior to TOC or Follow-Up Visits will be 
considered not achieving success as the microbiological response. Microbiological 
outcome will be derived and listed at early termination visit.

Microbiological outcome and response along with the 95% Clopper-Pearson CI for 
the percentage of microbiological response will be summarized for qualifying 
uropathogens isolated at baseline using the groups listed below at the On-therapy, 
TOC, and Follow-up visits using counts and percentages. Participant level 
microbiological response and 95% Clopper-Pearson CI will be summarized within the 
same table. The necessity of these categories will depend on the uropathogens that are 
recovered. Any additional uropathogens present in 10 or more participants will be

9.1.1.2.
Susceptibility

Results and interpretations of susceptibility testing for all uropathogens against 
gepotidacin and other antimicrobials will be summarized by uropathogen, visit, and 
antimicrobials tested. For summaries, a participant will be counted multiple times 
under an uropathogen category if multiple uropathogens within that uropathogen 
category are isolated at baseline for the participant.

The overall frequency distribution of minimum inhibitory concentrations (MICs) and 
the minimum, maximum, median (MIC50), and 90th percentile (MIC90) MIC will be 
presented. Percent susceptibility (susceptible, intermediate, or resistant) will be 
summarized where available.

Reduction in susceptibility to gepotidacin will be evaluated by comparing the 
baseline gepotidacin MIC value for uropathogens with the value obtained 
post-baseline. Post-baseline uropathogens of the same species and from the same 
participant with a confirmed ≥ 4-fold increase in gepotidacin MIC are considered to 
have developed a reduction in susceptibility to gepotidacin.


The number and percentage of participants who demonstrate a reduction in 
susceptibility to GSK 2140944 will be summarized by visit and uropathogen.
A participant will be counted multiple times under an uropathogen category if 
multiple uropathogens within that uropathogen category are isolated at baseline for 
the participant.
9.1.1.3.
Clinical Outcome and Response

Clinical signs and symptoms of acute cystitis will be recorded by site staff based on 
participant interview using the scoring system. 

The clinical signs and symptoms include at least dysuria, frequency, urgency, and 
lower abdominal or suprapubic pain. The clinical signs and symptoms will be scored 
from 0 to 3.

At Baseline, the participant must present with at least 2 signs and symptoms and have 
a total cumulative symptom score ≥2. At TOC, success is recorded as normal 
presentation of signs and symptoms with a total cumulative symptom score of zero 
and no new signs and symptoms of the infection under study.

The investigator will determine the clinical outcome by comparing the signs and 
symptoms of acute cystitis at the On-Therapy (Days 2 through 5 only), TOC, and 
Follow-up Visits to those present at Baseline. The clinical response based on 
investigator-determined clinical outcome will be programmatically derived using the 
criteria in Table 7.

The sponsor-determined clinical outcome and response will be programmatically 
determined by comparing the scores of the signs and symptoms of acute cystitis at the 
On-Therapy (Days 2 through 5 only), TOC, and Follow-up Visits to those present at 
Baseline as shown in Table 7.

Participants who withdraw from the study prior to TOC or Follow-Up Visits will be 
considered not achieving success as the clinical response at TOC or Follow-Up 
Visits. The investigator- and sponsor-determined clinical response and outcome at 
Early Termination visit will only be listed.

Clinical response (success or failure) will be determined at TOC or Follow-Up visits 
for each participant. A “success” clinical response is defined as if the clinical 
outcome for all qualifying uropathogens is “clinical success” for the visit, otherwise a 
“failure” clinical response will be assigned.

Clinical cure is defined in Table 8 and will be programmatically derived at the 
On Therapy (Days 2 through 5), TOC, and Follow-up Visits. If a participant does not 
meet clinical cure at TOC visit, the participant will not be considered as clinical cure 
at Follow-up visit.

The investigator- and sponsor-determined clinical outcome and response will be 
summarized for qualifying uropathogens isolated at baseline at the On-therapy, TOC, 
and Follow-up visits using counts and percentages. A participant will be counted 
multiple times under an uropathogen category if multiple qualifying uropathogens 
within that uropathogen category are isolated at baseline for the participant. In 
addition, participant level of clinical outcome will be summarized in the same table.
The 95% Clopper-Pearson CI will be presented for the proportion clinical response at 
each visit.

a.
If a participant discontinues during the on-treatment confinement period, Day 5 assessments will be completed before the participant is discharged, with the exception of study 
treatment administration.
b.
Based on confirmation of pyuria (≥10 WBC/mm3 or the presence of leukocyte esterase) and/or nitrite from a pretreatment clean-catch midstream urine sample per local laboratory 
procedures. Note: Repeat baseline urine samples are allowed if contamination, defined as ≥10 squamous epithelial cells, is observed under microscopic evaluation.
c.
Participants will provide a clean-catch midstream urine sample pretreatment at Baseline (predose on Day 1), predose on Days 2 through 5 (i.e., before the time-matched dose); and 
at the TOC and Follow-up Visits for Gram stain, quantitative bacteriology culture, and in vitro antimicrobial susceptibility testing.
d.
Site staff will record clinical signs and symptoms of acute cystitis based on participant interview.
e.
Obtain a triplicate 12-lead ECG in semi-supine position at Baseline only. See Table 10 for single 12-lead ECG predose and postdose assessment time points on Days 1 and 4.
f.
Only repeat the ECG and vital sign assessments at predose on Day 1 if the baseline assessment was not within 4 hours of the first dose of study treatment.
g.
Take measurement of temperature, blood pressure, and pulse rate in semi-supine position.
h.
If serology testing was performed within 3 months prior to the first dose of study treatment and results were positive, testing at Baseline is not required. If testing was performed 
within 3 months and any result was negative, testing at Baseline is required.
i.
For women of childbearing potential, a negative serum pregnancy test is needed for eligibility at Baseline. A urine pregnancy test may be performed on Day 5 and at the TOC Visit.
j.
The first dose on Day 1 will only be administered after all baseline procedures have been completed. All doses of study treatment will be administered under site staff supervision 
and all doses will be administered with food (i.e., standardized meals or snacks as applicable). Participants should remain in the clinic to complete a total of 10 doses.
k.
See Table 10 for serial collection time points. Predose PK blood samples will be collected before each time-matched dose on Days 1 through 5. Predose PK urine samples will be 
collected 0 to 2 hours before each time-matched dose on Days 1 through 5. Only 1 sample is needed when serial and predose samples overlap. If a participant is switched to a 
different antibiotic before the end of study treatment, a final blood and urine PK sample should be collected prior to administration of the different antibiotic.
l.
Collection of cervical, rectal, and pharyngeal swab PK specimens is optional. Specimens will be collected on Day 4 at predose and at approximately 2 hours postdose. The 2-hour 
postdose collection should be as close as possible to the 2-hour postdose blood PK draw time on Day 4.
m.
Collect sample only if the participant has a signed consent specific for this purpose. Baseline (predose on Day 1) is the recommended time to collect the sample, but it can be 
collected at any time during the study.
n.
Collection of stool, vaginal, and pharyngeal microbiome specimens is optional. The pretreatment specimens may be collected any time from Day -1 to Day 1 predose. The 
posttreatment specimens on Day 5 and at Follow-up may be collected at any time. Posttreatment stool, vaginal, and pharyngeal microbiome specimens should only be collected 
from participants who had a corresponding baseline specimen collected for each specimen type. 
o.
Record serious adverse events from the time of consent.

p.
Record adverse events from the time of the first dose of study treatment.
q.
Confirm return day/time for the TOC and Follow-up Visits.
r.
Pre-visit reminder: Site staff will contact the participant 24±4 hours before the scheduled TOC and Follow-up Visits.
Note:
At the discretion of the investigator, for emergency purposes only, participants may temporarily leave the clinic on study days without serial PK collections and only at times that do not 
interfere with required study assessments. Participants will be instructed to follow the protocol restrictions. The investigator will ensure the participant is eligible to continue in the study 
upon return to the clinic. All doses of study treatment will be administered under site staff supervision in the clinic.
The timing and number of planned study assessments, including PK assessments may be altered during the study based on newly available data (e.g., to obtain data closer to the time of 
peak plasma concentrations) to ensure appropriate monitoring. Any changes in the timing or addition of time points for any planned study assessments must be documented and 
approved by the relevant study team member and then archived in the sponsor and site study files, but will not constitute a protocol amendment. The institutional review board will be 
informed of any safety issues that require alteration of the safety monitoring scheme or amendment of the informed consent form.

Efficacy
Microbiology Procedures

Microbiology data will be received from two sources

Central laboratory

Excel spreadsheets from the study microbiologist and/or clinical scientist

The central laboratory will analyse the bacteriology urine samples by conducting a Gram stain, 
quantifying and identifying uropathogens and will perform susceptibility testing as listed below.

Broth microdilution results (MIC) on all gram-positive uropathogens for gepotidacin, ampicillin, 
trimethoprim-sulfamethoxazole, trimethoprim, sulfisoxazole, ciprofloxacin, levofloxacin, 
nitrofurantoin and vancomycin.

Broth microdilution results (MIC) on all gram-negative uropathogens for gepotidacin, ampicillin, 
amoxicillin/clavulanic acid, ceftolozatone/tazobactam, ceftazidime/avibactam, 
piperacillin/tazobactam, cefazolin, ceftriaxone, meropenem, amikacin, gentamicin, trimethoprim-
sulfamethoxazole, trimethoprim, sulfisoxazole, ciprofloxacin, levofloxacin, nitrofurantoin and 
vancomycin

Amoxicillin/clavulanic acid is tested in the ratio of 2:1, concentrations for 
amoxicillin/clavulanic acid will be expressed as the amoxicillin concentration. 
Piperacillin/tazobactam and ceftolozane/tazobactam are tested with the concentration of 
tazobactam fixed at 4 mg/L, concentrations for piperacillin/tazobactam and 
ceftolozane/tazobactam will be expressed as the piperacillin and ceftolozane 
concentration, respectively. Ceftazidime/avibactam is tested with the concentration of 
avibactam fixed at 4 mg/L, concentrations for ceftazidime/avibactam will be expressed as 
the ceftazidime concentration. Trimethoprim-sulfamethoxazole is tested in the ratio 1:19, 
concentrations for trimethoprim-sulfamethoxazole will be expressed as the trimethoprim 
concentration.

Gradient diffusion results (MIC) on all gram-negative and gram-positive uropathogens 
for:fosfomycin

All gram-negative uropathogens will be also be tested by broth microdilution (MIC) to determine 
indicate production of extended spectrum beta-lactamases (ESBLs). In accordance with the 
Clinical and Laboratory Standards Institute (CLSI) M100 guidelines (Table3A), ESBL production 
may be indicated by a MIC result of >1 mcg/mL for ceftriaxone ceftazidime, cefotaxime or 
aztreonam for E. coli, K. pneumoniae or K. oxytoca or a MIC result of >1 mcg/mL for ceftazidime, 
cefotaxime or cefpodoxime for P. mirabilis.

The data from the study microbiologist and/or clinical scientist will include clarification of which isolates 
should be labelled as uropathogens and qualifying uropathogens and a determination of whether the 
susceptibility results for identically labelled uropathogens from the same participant at the same visit 
differ enough to classify the uropathogens as separate.

Microbiological Data Procedures

Statistics and Programming will identify all cases within the central laboratory dataset where two or 
more uropathogens of the same genus and species have been identified for the same participant at the 
same visit.

An excel file containing a list of these uropathogens and the associated quantitative bacterial counts 
and MIC results for each isolate will be provided to the microbiologist.

The microbiologist will review the list and determine if the isolates are the same or different strains of 
the identified uropathogen based on the susceptibility data patterns.

If there is a ≥ 4-fold difference in MIC to one member of two or more antibiotic classes, then the 
two isolates will be considered two different strains and both will be used in the analysis.

Otherwise, only one isolate will be kept for analysis based on a pre-defined algorithm.

The microbiologist will add a flag to the list to indicate which of the duplicate records to keep. All 
records will be kept in the SDTM datasets, and those records that are deemed to be duplicates will be 
removed from the final Analysis Data Model (ADaM) dataset.

For participants whom the microbiologist has indicated that both sets of uropathogen records should be 
maintained, Statistics and Programming will provide all central laboratory data from all visits for the
particular uropathogens to the microbiologist.

Should the same uropathogen be presented at additional visits, the microbiologist, with the use of the 
MIC result, will make a determination as to which of the baseline uropathogens has been isolated at 
this new visit.

Statistics and Programming will also provide a list of all distinct isolates (by participant, visit, 
identification, and quantitative bacterial count) from the central laboratory to the microbiologist and 
clinical scientist. 

The microbiologist and clinical scientist will provide an excel spreadsheet containing a list of decoded 
uropathogen codes and a flag to indicate which items within the code list are uropathogens and 
qualifying uropathogens for this protocol. This flag will then be merged into the SDTM dataset.
Fold Change

Fold change will be used to describe how much the MIC for gepotidacin changes between baseline and 
subsequent visits for the same bacterial species from the same participant.

Fold change will be calculated (in doubling dilutions) as the ratio of the MIC at the subsequent visit to 
the MIC at baseline visit.
Susceptibility Interpretations

Susceptibility interpretations will be calculated and reported by the central laboratory and will be based 
on the CLSI M100 guidelines in effect at that time the bacterial isolate is tested. 

Since CLSI breakpoints for certain drug/bug combinations can change in new yearly editions of M100 
guidelines, as GSK and/or the central laboratory become aware of relevant breakpoint changes, the 
central laboratory will identify any reports which would qualify as needing a change in interpretation (e.g. 
a MIC value that was originally reported as susceptible, and would now be considered resistant based 
on the new breakpoint), and will issue amended reports. 

The final clinical database will report interpretations according to the most recent CLSI M100 
interpretations regardless of what the breakpoints were at the time the isolate was initially tested.

Quantitative Bacterial Counts

The central laboratory will quantitatively determine the growth of bacterial uropathogens from culture of 
participant urine samples.

The central laboratory will report the following quantification results
o
If there is no growth on the culture plates for a urine sample: 

No growth (<10^3) 
o
If there is growth on the urine culture plates for a urine sample, each uropathogen will receive an 
associated colony count:

10^3-<10^4

10^4-<10^5

>/-10^5

At subsequent visits, determination of ‘no growth’ for individual uropathogens will need to be derived 
from an overall urine culture result of no growth (meaning there was no growth on the urine culture 
plates) or no identification/quantification being reported for that specific uropathogen (assuming that a 
urine sample was taken and that results were reported).

If the bacterial sample at a subsequent visit is not collected then it’s considered as “unable to 
determine” for the uropathogens identified at baseline.

Handling of Missing and Partial Dates
Element
Reporting Detail
General

Partial dates will be displayed as captured in subject listing displays.
Adverse 
Events

The eCRF allows for the possibility of partial dates (i.e., only month and year) to be 
recorded for AE start and end dates; that is, the day of the month may be missing. In 
such a case, the following conventions will be applied for calculating the time to onset 
and the duration of the event:
o
Missing Start Day: First of the month will be used unless this is before the start 
date of study treatment; in this case the study treatment start date will be used and 
hence the event is considered On-treatment as per Appendix 3: Study Phases 
and Treatment Emergent Adverse Events.
o
Missing Stop Day: Last day of the month will be used, unless this is after the stop 
date of study treatment; in this case the study treatment stop date will be used.

Completely missing start or end dates will remain missing, with no imputation applied. 
Consequently, time to onset and duration of such events will be missing.

Adverse events with entirely missing or unknown start dates will be assumed to be 
on-treatment for reporting.
