Overall Design: This is a Phase 1, open-label, fixed-sequence, 1-way DDI study 
designed to assess the PK, pharmacodynamics (PD), safety, and tolerability of 
GSK3640254 and an oral contraceptive containing EE/LNG (Portia) when administered 
alone and in combination in healthy female participants.
The study will consist of a screening period, check-in, a run-in period, and a treatment 
period with Portia given alone and in combination with GSK3640254. Participants will 
be screened within 28 days before check-in (Day -4). 
Participants should take Portia in the morning at approximately the same time throughout 
study participation. During the treatment period, the participants will fast overnight for at 
least 8 hours prior to GSK3640254 dosing and will receive a moderate fat meal 
30 minutes prior to dosing. Participants will eat this meal in 30 minutes or less. Dose 
administration will occur within 5 minutes of completion of meal consumption.
Blood samples for the analysis of EE and LNG will be collected before dosing on Days 9 
to 10 and 19 to 21, and up to 24 and 72 hours after dosing on Days 10 and 21 of the 
treatment period, respectively. Blood samples for the analysis of GSK3640254 will be 
collected before dosing on Days 19 to 21, and up to 96 hours after dosing on Day 21 of 
the treatment period. 
Blood samples for the analysis of progesterone, follicle-stimulating hormone (FSH), and 
luteinizing hormone (LH) will be collected on Days 1, 10, 11, 21, and 22 of the treatment 
period.
Safety and tolerability will be assessed by monitoring and recording of adverse events, 
clinical laboratory test results, vital sign measurements, 12-lead electrocardiogram (ECG) 
results, and physical examination findings.
Study assessments will be performed as indicated in the Schedule of Activities (SoA). 
Participants will check into the clinic on Day -4 and will remain confined until discharge 
on Day 25.
Disclosure Statement: This is a single group, single arm study that has no masking.
Number of Participants: Approximately 25 participants will be treated to ensure that 
20 evaluable participants complete the study.
Intervention Groups and Duration: The treatments will be as follows:

Run-in Period: Portia (0.03 mg EE/0.15 mg LNG) once daily (QD) Days -3 to -1

Treatment A: Portia (0.03 mg EE/0.15 mg LNG) QD on Days 1 to 10 of the 
treatment period

Treatment B: Portia (0.03 mg EE/0.15 mg LNG) QD coadministered with 
GSK3640254 200 mg on Days 11 to 21 of the treatment period
The duration of the study, including Screening and Run-in, is approximately 8 weeks.

peak plasma concentrations) to ensure appropriate monitoring. 

Any changes in the timing or addition of time points for any planned study assessments as the result of emerging PK/PD data
from this study 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 (IRB)/Independent Ethics Committee 
(IEC) will be informed of any safety issues that constitute a substantial amendment and require alteration of the safety 
monitoring scheme or amendment of the informed consent form (ICF).

INTRODUCTION
2.1.
Study Rationale
This is an open-label, single-sequence, 1-way drug-drug interaction (DDI) study to 
investigate the effect GSK3640254 has on the PK of a combination oral contraceptive 
containing ethinyl estradiol (EE) and levonorgestrel (LNG). Effective contraception for 
women infected with human immunodeficiency virus (HIV) is important in the 
prevention of unplanned pregnancies.
2.2.
Background
GSK3640254 is an HIV maturation inhibitor (MI) which is improved over prior 
developmental MIs in the following ways: (1) it exhibits significantly improved 
pan-genotypic coverage and potency against polymorphic variants; (2) in vitro data 
suggest that GSK3640254 exhibits a higher barrier to emergence of resistant viruses 
(except for A364V); (3) GSK3640254 has improved potency in vitro toward all HIV-1 
subtypes; (4) it has potential for improved gastrointestinal (GI) tolerability; and (5) it has 
a projected lower once-daily human dose. Summaries of the pre-clinical and clinical 
studies are included in the Clinical Investigator's Brochure (CIB) [GSK Document 
Number 2018N379610_00].
2.2.1.
Background and Key Safety Data with a Prior Maturation Inhibitor
Bristol-Myers Squibb (BMS), and later ViiV Healthcare (VH), developed a structurally 
similar HIV-1 MI (BMS-955176/GSK3532795), which was studied through Phase 2b 
studies in both treatment-naïve (AI468038/205891) and experienced (AI468048/205892) 
HIV-1 infected adults. In study AI468038/205891, a greater number of participants who 
received GSK3532795 experienced GI intolerability (most frequently Grade 1 to 2 
diarrhea and abdominal pain). A detailed examination of all GI adverse events (AEs) 
(regardless of grade/relationship) revealed a relationship with dose [GSK Document 
Number 2016N302783_00]. Ultimately, the rate of GI intolerability in the GSK3532795 
dose groups in the Phase 2b study 205891 in part led to VH’s decision to end all trials 
and not progress to Phase 3 studies. Gastrointestinal AEs were also previously observed 
in healthy participants in Phase 1 studies with varying doses, durations, and formulations 
of GSK3532795. In both studies, the most common GI AEs were abdominal pain and 
diarrhea.
Aside from mild to moderate GI intolerability, 2 serious adverse events (SAEs) occurred 
in the Phase I Thorough QT study AI468044/206220 [BMS Document Control 
Number 930109388] at supra-therapeutic doses: 1 healthy participant had an episode of 
acute psychosis and another had suicidal ideation/homicidal ideation as diagnosed 
through an interview by a psychiatrist. The 2 participants received GSK3532795 240 mg 
twice daily and 240 mg once daily (QD) with food, respectively. These events were 
assessed as related to study drug but were not observed in any other clinical study with 
GSK3532795. The most frequent neuropsychiatric AEs in studies with GSK3532795 
were headache, dizziness, and sleep abnormalities (e.g., insomnia, abnormal dreams).

Preliminary Safety and Pharmacokinetic Data in Study 207187
The primary objective of the first time in human (FTIH) clinical trial (207187) was to 
investigate the safety and tolerability of GSK3640254 following single and repeated daily 
administration. A total of 78 healthy men were ultimately randomized: 20 in the 
single-ascending dose (SAD, doses ranging from 1 to 700 mg) and 58 in the 
multiple-ascending dose (MAD, 50 to 320 mg QD for 14 days). A comprehensive 
summary of results is described in the CIB [GSK Document Number 2018N379610_00] 
and the Study Synopsis [GSK Document Number 2018N375461_00]. A concise 
summary of the data is presented below.
No deaths or SAEs were reported. There were 4 AEs leading to discontinuation. Only 1 
of these AEs was related to study medication. A subject who received GSK3640254 
200 mg QD developed a maculopapular rash after 8 days of study medication. The rash 
lasted for 6 days and there were no laboratory abnormalities. A dermatology consultant 
concluded this was a drug rash and the subject later received fexofenadine 180 mg QD/a 
topical steroid cream with resolution. The other 3 AEs occurred in SAD portion of the 
study (depression in a subject who received placebo and 2 subjects with viral infection). 
There were 9 subjects with 12 AEs assessed as related to study medication by the 
principal investigator (11 Grade 1; 1 Grade 2). The most clinically notable was a subject 
who developed elevated transaminases while receiving GSK3640254 50 mg QD for 
14 days. Specifically, there was a progressive rise in alanine aminotransferase (ALT) 
during treatment with a peak ALT of 83 IU/L on Day 16. The remaining liver chemistries 
were normal throughout. An ultrasound showed a subcapsular area of heterogenous 
echogenicity within segment 7, measuring approximately 35 × 23 × 36 mm. Follow-up 
magnetic resonance imaging and liver chemistries were normal. This subject also had 
3 unrelated AEs during the course of an isolated increased ALT: musculoskeletal 
stiffness, contact dermatitis, and headache. All other related AEs are described in the CIB 
[GSK Document Number 2018N379610_00] and the Study Synopsis [GSK Document 
Number 2018N375461_00].
In the SAD portion of the study, 17 subjects experienced 60 individual AEs (58 Grade 1; 
2 Grade 2). The 2 Grade 2 AEs were headache and depression (both unrelated). The most 
frequent AEs were headache, contact dermatitis primarily due to electrocardiogram 
(ECG) electrodes, and diarrhea. There was no dose/AE relationship. 
In the MAD portion of the study, 44 subjects experienced 130 individual AEs 
(126 Grade 1; 4 Grade 2). The 3 Grade 2 AEs were headache (1 related and 1 unrelated) 
and back pain (2 unrelated). The most frequent AEs were headache, contact dermatitis, 
dizziness, contusion, fatigue, and back pain.
There were no clinically significant abnormal fluctuations or trends in vital signs in the 
SAD or MAD cohorts. There were no abnormal clinically significant arrhythmias or QT 
prolongations (values >500 ms or increases >60 ms from Baseline) observed for any 
participant in the SAD or MAD. A cardiodynamic evaluation of healthy subjects in the 
MAD portion of Study 207187 (placebo or GSK3640254 dose range 50 to 320 mg daily 
for 14 days) was performed. Serial ECGs were extracted from continuous Holter 
monitors at time-matched baseline on Day -1 and for approximately 24 hours post-dose

on Days 1 and 14. In the concentration-QTc analysis, a final model with a treatment 
effect-specific intercept reasonably represented the data. The slope of the 
concentration-QTc relationship was 0.004 ms per ng/mL (90% confidence interval [CI]: 
0.0023 to 0.0048) with a small treatment effect-specific intercept of -0.9 ms (90% CI: 
-4.47 to 2.69). The QT effect (∆ΔQTcF) of GSK3640254 could be predicted to be 
5.38 ms (90% CI: 1.66 to 9.10) and 6.70 ms (90% CI: 2.79 to 10.61) for the 200 mg 
(1779 ng/mL) and 320 mg (2154 ng/mL) doses, respectively, on Day 14. Based on this 
concentration-QTc analysis, a QTcF effect above 10 ms could be excluded up to 
GSK3640254 plasma concentrations of approximately 2000 ng/mL (corresponding to 
doses approximately ≤200 mg QD; note, the dose used in this study is 200 mg QD). 
Finally, there were no laboratory abnormality trends across doses that were clinically 
significant or associated with any symptoms.
Preliminary GSK3640254 PK parameters derived based on nominal sampling times 
following single doses of 1 to 700 mg administered after a moderate calorie and fat 
breakfast showed GSK3640254 was slowly absorbed with a median time of maximum 
observed concentration (Tmax) observed between 3 to 4.5 hours after dosing with a 
moderate fat breakfast and slowly eliminated with a mean half-life ranging from 22 to 
26 hours. In general, exposure (maximum observed concentration [Cmax] and area under 
the concentration-time curve [AUC]) increased in a close-to-dose-proportional manner 
from 1 to 400 mg with no further increase in exposure at 700 mg. 
Repeat dose preliminary PK parameters following administration of GSK3640254 50 to 
320 mg QD for 14 days were determined on Day 1 and Day 14 and showed a median 
Tmax ranging between 3.8 to 4.3 hours. The mean half-life ranged from approximately 
22 to 29 hours. Overall, there was a trend of a slightly less than dose-proportional 
increase in Cmax and AUC from time 0 to 24 hours after dosing (AUC[0-24]) from 50 to 
320 mg. The exposure on Day 14 was, on average, 1.9- to 2.3-fold higher than that of 
Day 1 for Cmax and 2.2- to 2.6-fold higher than Day 1 for AUC(0-24). Detailed 
summary statistics are available in the Study Synopsis [GSK Document 
Number 2018N375461_00].
2.2.3.
Preliminary Safety and Pharmacokinetic Data in Study 208131
The FTIH Study 207187 used a bis-hydrochloride salt capsule formulation of 
GSK3640254, which is not suitable for long term clinical development. 
Study 208131 was a single-center, open-label, 2-period, 2-sequence crossover design, 
conducted in 14 healthy subjects in the United Kingdom. This study was designed to 
assess the relative bioavailability of the formulation planned for Phase 2a (mesylate salt 
in a capsule) to the FTIH formulation (bis-hydrochloride salt in a capsule) administered 
following a moderate calorie and fat meal. All subjects completed dosing and the blinded 
preliminary safety data showed a total of 11 AEs (all Grade 1). Two AEs of headache 
were related to study drug. The most common AE was headache (3 instances). There 
were 3 GI AEs (abdominal pain, bleeding gums, and flatulence). There were no cardiac 
or psychiatric AEs. There were no clinically significant changes in vital signs, ECG 
parameters, or safety laboratory parameters.

Preliminary PK results from study 208131 showed that in the presence of a moderate fat 
meal, the relative bioavailability of GSK3640254 following 200 mg GSK3640254 
mesylate salt administration relative to 200 mg GSK3640254 bis-hydrochloride salt 
administration was 110% and 116% based on AUC from time zero extrapolated to 
infinity (AUC[0-]) and Cmax, respectively.
2.2.4.
Ethinyl Estradiol and Levonorgestrel
Portia has been marketed in the United States (US) since 2002 as a combination oral 
contraceptive. Portia contains 0.03 EE and 0.15 mg LNG. Each blister card provides 21 
pink active tablets, and 7 white inert tablets. Combination oral contraceptives act by 
suppression of gonadotropins. Although the primary mechanism of this action is 
inhibition of ovulation, other alterations include changes in the cervical mucus (which 
increases the difficulty of sperm entry into the uterus) and endometrium (which reduces 
the likelihood of implantation). When taken correctly, oral contraceptives have a failure 
rate of less than 1% per year [Levonorgestrel and Ethinyl Estradiol, 2012].
Portia is administered orally. Both EE and LNG are widely distributed. Ethinyl estradiol 
is highly protein-bound to albumin and induces an increase in the serum concentrations 
of both sex hormone-binding globulin (SHBG) and corticosteroid binding globulin. 
Levonorgestrel is strongly protein-bound, primarily to albumin and SHBG. Steady state 
is reached in approximately 11 days. Excretion of the oral contraceptive steroids as 
inactive metabolites occurs via the urine and feces. Elimination half-life is approximately 
15 hours for EE and 30 hours for LNG at steady state. It is the prolonged biologic effects 
of the hormones that allows for once-daily administration [Levonorgestrel and Ethinyl 
Estradiol, 2012].
2.3.
Benefit/Risk Assessment
Based upon preclinical and clinical studies, the major risks for GSK3640254 are GI 
intolerability (e.g., abdominal pain and diarrhea) and toxicity, prolongation of the 
corrected QT interval (QTc), and neuropsychiatric safety. Reproduction of preclinical GI 
toxicity findings (e.g., single-cell parietal cell necrosis) would be unlikely during the 
limited dosing of GSK3640254 in this study. One preclinical study showed 1 dog with an 
increased QTc interval when given a single dose of GSK3640254. As described in 
Section 2.2.2, a cardiodynamic analysis of healthy subjects in Study 207187 was 
conducted. A final model from the MAD data showed a QT effect (∆ΔQTcF) of 
GSK3640254 could be predicted to be 5.38 ms (90% CI: 1.66 to 9.10) and 6.70 ms 
(90% CI: 2.79 to 10.61) for the 200 mg (1779 ng/mL) and 320 mg (2154 ng/mL) doses, 
respectively, on Day 14. Based on this concentration-QTc analysis, a QTcF effect above 
10 ms could be excluded up to GSK3640254 plasma concentrations of approximately 
2000 ng/mL (corresponding to doses approximately ≤200 mg QD; note, 200 mg QD is 
the dose used in this study). Importantly, there were no abnormal clinically significant 
arrhythmias or QTc prolongations (values >500 ms or increases >60 ms from Baseline) in 
Study 207187. This study contains specific cardiac exclusion criteria, has ECG 
monitoring (at Tmax once GSK3640254 attains steady state concentration), and has 
QTcF based stopping criteria.

Finally, the protocol will exclude potential participants with any significant pre-existing 
psychiatric condition or positive (abnormal) response confirmed by the investigator on a 
clinician (or qualified designee) administered Columbia Suicide Severity Rating Scale 
(C-SSRS). The C-SSRS assessment will also be administered by a clinician (or qualified 
designee) during the on-treatment portion of the study.
To ensure the overall safety of participants (including, but not limited to, the risk of GI 
intolerability, QTc prolongation, and neuropsychiatric safety), this clinical study will 
include healthy adults who will receive clinical, ECG, and laboratory evaluations during 
their participation. More detailed information about the known and expected benefits and 
risks and reasonably expected AEs of GSK3640254 may be found in the CIB [GSK 
Document Number 2018N379610_00].
The use of oral contraceptives is associated with increased risks of several serious 
conditions including venous and arterial thrombotic and thromboembolic events (such as 
myocardial infarction, thromboembolism, and stroke), hepatic neoplasia, gallbladder 
disease, and hypertension, although the risk of serious morbidity or mortality is very 
small in healthy women without underlying risk factors. Common side effects include 
headache, vaginal bleeding, nausea/vomiting, acne, dysmenorrhea, increased weight, 
mood changes, anxiety/panic attacks, breast pain, and migraines. More detailed 
information about the known and expected risks and reasonably expected AEs for 
EE/LNG may be found in the package insert [Levonorgestrel and Ethinyl Estradiol, 
2012].

Preclinically, GSK3640254 inhibited cardiac 
hERG/IKr potassium, cardiac SCN5A sodium and 
L-type calcium channel currents recorded from 
HEK 293 cells stably transfected with 
complementary DNA from the ion channels. In a 
single-dose safety pharmacology study in 
telemeterized dogs, increases in QT interval (up 
to 20 ms) occurred primarily in 1 dog given 
17 mg/kg. Later, there were no GSK3640254-
related effects on electrocardiogram (ECG) 
parameters in dogs given up to 25 mg/kg/day for 
4 weeks.
In the first time in human study 207187, no 
participant exhibited QTc change from baseline 
>60 ms or QTc >500 ms. As described in 
Section 2.3, in the concentration-QTc analysis, a 
QTcF effect above 10 ms could be excluded up to 
GSK3640254 plasma concentrations of 
approximately 2000 ng/mL (corresponding to 
doses approximately ≤200 mg QD).
Screening: Protocol exclusion criteria based on 
screening ECG parameters and cardiac medical 
history.
On-Treatment: Participants will have ECG monitoring 
(at a clinically reasonable frequency) during the 
course of the study (see SoA, Section 1.3) with QTc

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
Gastrointestinal (GI) intolerability and 
toxicity
Clinical signs indicative of GI intolerability 
(sporadic vomiting and abnormal feces beginning 
on Day 1 and continuing throughout the dosing 
periods) occurred mainly in dogs at 
1 mg/kg/day. Additionally, toxicity findings of 
single-cell necrosis of parietal cells and/or chief 
cells were present in preclinical species. These 
findings were reversible. Finally, GI intolerability 
(predominately abdominal pain and diarrhea) was 
seen with a structurally related compound 
GSK3532795 which was evaluated through 
Phase 2b dosing. 
Screening: Protocol exclusion criterion based on 
pre-existing GI pathology or baseline GI 
signs/symptoms.
On-Treatment: Participants will undergo continuous 
evaluation for AEs during their participation in the 
study; there will be individual clinical stopping criteria 
based upon intensity of treatment-emergent AEs. A GI 
toxicity evaluation and monitoring plan will be 
available to guide investigators should GI AEs emerge 
(See Section 8.2.6).
Neurologic/psychiatric safety
Two psychiatric serious adverse events in 
previous maturation inhibitor GSK3532795 clinical 
program (acute psychosis, homicidal/suicidal 
ideation) were seen at supratherapeutic doses in 
healthy subjects in the thorough QT (TQT) study.
From a neurologic and psychiatric AE summary 
and pharmacokinetic/pharmacodynamic analysis 
for GSK3532795 across all studies mild Grade 1 
headache and Grade 1 sleep abnormalities were 
the predominant AEs, with a trend for increasing 
neurologic and psychiatric AEs with increasing 
dose (based on TQT and Phase 2b studies). No 
exposure-response relationship was seen for 
select neurologic and psychiatric AEs (based on 
TQT and Phase 2b studies). Central nervous 
system penetration data for GSK3532795 and 
GSK3640254 in rats demonstrate a similarly low 
Screening: Protocol exclusion criterion based on any 
pre-existing psychiatric condition (including results of 
psychological assessment) for participants. 
Participants will have a clinician (or qualified 
designee) administered Columbia Suicide Severity 
Rating Scale (C-SSRS) and will be included given no 
positive (abnormal) response.
On-Treatment: Participants will undergo physical 
examinations and laboratory testing. In addition, 
participants will undergo continuous evaluation for 
AEs during their participation in the study; there are 
individual clinical stopping criteria and monitoring 
based upon incidence and intensity of 
treatment-emergent psychiatric AEs (Section 7.1.4
and Section 8.2.5).

Overall Benefit: Risk Conclusion
Given the preclinical profile of GSK3640254, the clinical profile of a structurally similar 
MI (GSK3532795), the clinical data gathered from Studies 207187 and 208131, and the 
planned clinical procedures and evaluations in this study, the potential risks to 
participants receiving GSK3640254 are low, evaluable, and manageable. Given the years 
of experience with combination contraceptives such as Portia, the potential risks to 
participants receiving Portia are low, evaluable, and manageable. More detailed 
information about the known and expected risks and reasonably expected AEs for 
EE/LNG may be found in the package insert [Levonorgestrel and Ethinyl Estradiol,

STUDY DESIGN
4.1.
Overall Design
This is a Phase 1, open-label, fixed-sequence, 1-way DDI study designed to assess the 
PK, PD, safety, and tolerability of GSK3640254 and an oral contraceptive containing 
EE/LNG (Portia) when administered alone and in combination in healthy female 
participants.
The study will consist of a screening period, check-in, a run-in period, and a treatment 
period with Portia given alone and in combination with GSK3640254. Participants will 
be screened within 28 days before check-in (Day -4). The treatments will be as follows:

Run-in Period: Portia (0.03 mg EE/0.15 mg LNG) QD (Days -3 to -1)

Treatment A: Portia (0.03 mg EE/0.15 mg LNG) QD on Days 1 to 10 of the 
treatment period

Treatment B: Portia (0.03 mg EE/0.15 mg LNG) QD coadministered with 
GSK3640254 200 mg on Days 11 to 21 of the treatment period
Participants should take Portia in the morning at approximately the same time throughout 
study participation. 
During the treatment period, participants will fast overnight for at least 8 hours prior to 
dosing with GSK3640254 and will receive a moderate fat meal 30 minutes prior to 
dosing. Participants will eat this meal in 30 minutes or less. Dose administration will 
occur within 5 minutes of completion of meal consumption.
Blood samples for the analysis of EE and LNG will be collected before dosing on Days 9 
to 10 and 19 to 21, and up to 24 and 72 hours after dosing on Days 10 and 21 of the 
treatment period, respectively. Blood samples for the analysis of GSK3640254 will be 
collected before dosing on Days 19 to 21, and up to 96 hours after dosing on Day 21 of 
the treatment period.
Blood samples for the analysis of progesterone, follicle-stimulating hormone (FSH), and 
luteinizing hormone (LH) will be collected on Days 1, 10, 11, 21, and 22 of the treatment 
period.
Safety and tolerability will be assessed by monitoring and recording of AEs, clinical 
laboratory test results, vital sign measurements, 12-lead ECG results, and physical 
examination findings.
Study assessments will be performed as indicated in the Schedule of Activities (SoA)
(Section 1.3). Participants will check into the clinic on Day -4 and will remain confined 
until discharge on Day 25. The duration of the study, including Screening and Run-in, is
approximately 8 weeks.

Scientific Rationale for Study Design
This is an open-label, fixed-sequence, 1-way drug interaction study to investigate the 
effect GSK3640254 has on the PK of a combination oral contraceptive containing EE and 
LNG.
The inhibitory potential (direct and metabolism-dependent inhibition) of GSK3640254 
towards 7 major human hepatic cytochrome P450 (CYP) enzymes was evaluated in 
human liver microsomes [CIB, GSK Document Number 2018N379610_00]. 
GSK3640254 demonstrated minimal direct inhibition of all 7 CYP isoforms tested (half 
maximal inhibitory concentration [IC50] values >13.3 µM). At the maximum projected 
clinical dose of 200 mg, there is a low risk for clinically meaningful CYP-mediated DDIs 
with substrates of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6 and 
CYP3A4.
GSK3640254 did not demonstrate human pregnane X receptor or vitamin D receptor 
mediated transactivation of CYP3A. Therefore, it is unlikely that GSK3640254 would 
induce CYP3A, or other pregnane X receptor and vitamin D receptor regulated 
enzymes/transporters in humans. In addition, GSK3640254 was tested in a panel of CYP 
induction assays using inducible cryopreserved human primary hepatocytes and showed 
no induction (half maximal effective concentration > 5 µM) of CYP3A4, CYP2B6, and 
CYP1A2.
GSK3640254 is an inhibitor of organic anion-transporting polypeptide (OATP)1B3 and 
multi-drug resistance protein (MRP)2 in vitro and has the potential of generating DDIs 
with substrates of these transporters at the projected human systemic exposures. The 
IC50 values of GSK3640254 against OATP1B3 and MRP2 were 0.55 and 2.2 µM, 
respectively. In addition, GSK3640254 was an inhibitor of uridine diphosphate 
glucuronosyltransferase (UGT)1A1 in vitro (IC50 = 3.9 µM) and clinical DDIs via this 
mechanism could be possible although literature reports have not revealed clinically 
significant DDIs with greater than 2-fold change in exposure, with a few exceptions, due 
to UGT1A1 inhibition [Lin, 2002; Williams, 2004]. A clinically meaningful DDI risk due 
to UGT1A1 inhibition by GSK3640254 is likely minimal.
Sulfate conjugation accounts for approximately 60% of the first-pass metabolism of EE 
and once absorbed, hydroxylation by CYP3A4 and glucuronidation occur. GSK3640254 
has an unknown impact on sulfotransferases. Ethinyl estradiol is an inhibitor of 
CYP2C19, CYP3A4, and UGT. There is a risk that GSK3640254 may impact EE 
exposure due to its effect on UGT and its unknown effect on sulfotransferases.
Levonorgestrel and its Phase I metabolites are excreted primarily as glucuronide 
conjugates. Levonorgestrel is not subject to first pass metabolism and has nearly 100% 
bioavailability, therefore, there is low likelihood of a DDI at the absorption step.
This study is designed in accordance with the US Food and Drug Administration 
Guidance for Industry, Clinical Drug Interaction Studies - Study Design, Data Analysis, 
and Clinical Implications [DHHS, 2017] to assess the PK, safety, and tolerability of 
GSK3640254 and EE/LNG when administered alone and in combination.

Justification for Dose
The dose of 200 mg GSK3640254 was selected for this study as the maximum projected 
clinically therapeutic dose of GSK3640254 is 200 mg QD. The apparent terminal phase 
half-life (t1/2) of GSK3640254 was approximately 22 hours in the MAD portion of 
Study 207187 at the 200-mg dose, and predicted time to steady state is approximately 
5 days. The doses of 0.03 mg EE/0.15 mg LNG in Portia are standard, effective doses for 
an oral contraceptive.

subject. The documentation on male sterility can come from the site 
personnel’s review of subject’s medical records, medical examination and/or 
semen analysis, or medical history interview provided by her or her partner.

Sexual abstinence. Note: Sexual abstinence is considered a highly effective 
method only if defined as refraining from penile-vaginal intercourse on a long 
term and persistent basis when this is their preferred and usual lifestyle. 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.
d. Participants who have been on a stable regimen of an oral contraceptive for at 
least 3 consecutive months must be without evidence of breakthrough bleeding or 
spotting. 
e.
Participants who have been taking oral contraceptives should continue their 
current regimen until check-in to the clinic for the run-in period. Participants not 
currently taking an oral contraceptive are eligible, provided all other eligibility 
criteria are met.
f.
Participants may proceed to the treatment period provided the toxicity profile 
during the run-in period with Portia is acceptable in the opinion of the 
investigator.
g. Participants must agree to use an additional method of contraception from the list 
of contraceptive methods below for the run-in period, treatment period, and for 
28 days after the last dose of study intervention:

7.1.1.
Liver Chemistry Stopping Criteria
Liver chemistry stopping and increased monitoring criteria have been designed to assure 
participant safety and evaluate liver event etiology (in alignment with the Food and Drug 
Administration premarketing clinical liver safety guidance: 
https://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guid
ances/UCM174090.pdf).
Discontinuation of study intervention for abnormal liver tests is required when a 
participant has an ALT ≥3 × ULN or if the investigator believes study intervention 
discontinuation is in the best interest of the participant. 
Details of liver safety follow-up procedures are described in Appendix 5.
7.1.1.1.
Study Intervention Restart or Rechallenge after liver stopping criteria 
met
Study intervention restart or rechallenge after liver chemistry stopping criteria are met by 
any participant in this study is not allowed.
7.1.2.
QTc Stopping Criteria
The same Fridericia QT correction formula (QTcF) 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.

The Baseline QTcF should be based on averaged QTcF values of triplicate 
ECGs obtained over a brief (e.g., 5 to 10 minute) recording period from the 
Day -4 ECG.

A randomized participant that develops an on-treatment QTcF >500 ms or an 
increase from baseline QTcF >60 ms should have two repeat unscheduled ECGs 
within 10 minutes. Using these triplicate ECGs, if the average QTcF >500 ms or 
an increase from baseline QTcF >60 ms, the participant will be withdrawn from 
the study. Finally, this participant should have repeated unscheduled ECGs until 
their QTcF measurement returns to their original averaged QTcF value at 
Day -4.
See the SoA (Section 1.3) for data to be collected at the time of intervention 
discontinuation and follow-up and for any further evaluations that need to be completed.
7.1.3.
Columbia Suicide Severity Rating Scale Criteria
Emergence of any positive (abnormal) response confirmed by the investigator on a 
clinician (or qualified designee) administered C-SSRS during the on-treatment phase of 
the study will be cause for discontinuation of study intervention.
Refer to the SoA (Section 1.3) for data to be collected at the time of intervention 
discontinuation and follow-up and for any further evaluations that need to be completed.

7.1.4.
Individual Participant Laboratory Abnormality and Adverse Event 
Stopping Criteria
Investigators should make every effort to have a discussion with the medical monitor 
before the next dose to help assess if the study intervention should be stopped. 

Any clinically significant AE deemed to require discontinuation of study 
intervention

Any Grade 3 or higher rash or Grade 2 rash with evidence of systemic 
involvement 

Any allergic or hypersensitivity reactions to either or both drugs

Any Grade 3 or higher psychiatric AE

New onset suicidal ideation

Any Grade 3 or higher AE related to study intervention

Any Grade 4 AE or laboratory abnormalities (with the exception of an 
asymptomatic Grade 4 cholesterol, triglyceride, or CPK increase)
7.2.
Participant Discontinuation/Withdrawal from the Study

A participant may withdraw from the study at any time at her own request or 
may be withdrawn at any time at the discretion of the investigator for safety, 
behavioral, compliance, or administrative reasons. This is expected to be 
uncommon.

A participant who is withdrawn from the study for any reason related to safety 
(listed in Section 7.1.4 or otherwise) will be continued to be followed to assess 
the outcome of the safety event that triggered discontinuation of study drug.

At the time of discontinuing from the study, if possible, an early discontinuation 
visit should be conducted, as shown in the SoA. See SoA (Section 1.3) for data 
to be collected at the time of study discontinuation and follow-up and for any 
further evaluations that need to be completed.

The participant will be permanently discontinued both from the study 
intervention and from the study at that time.

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, she may request destruction of any 
samples taken and not tested, and the investigator must document this in the site 
study records.
7.3.
Lost to Follow Up
A participant will be considered lost to follow-up if she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site. 


2018N383291_00
CONFIDENTIAL
208135
35
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, she will be considered to 
have withdrawn from the study. 
Discontinuation of specific sites or of the study as a whole are handled as part of
Appendix 4.
8.
STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA (Section 1.3). 

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 intervention.

Adherence to the study design requirements, including those specified in the 
SoA, 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 
the SoA.

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.

8.2.
Safety Assessments
Planned time points for all safety assessments are provided in the SoA (Section 1.3).
8.2.1.
Physical Examinations

A full physical examination will include, at a minimum, assessments of the skin, 
cardiovascular, respiratory, GI, and neurological systems. Height and weight 
will also be measured and recorded.

A brief physical examination will include, at a minimum, assessments of the 
skin, lungs, cardiovascular system, and abdomen (liver and spleen).

Investigators should pay special attention to clinical signs related to previous 
serious illnesses.
8.2.2.
Vital Signs

Oral temperature, pulse rate, respiratory rate, and blood pressure will be 
assessed.

Blood pressure and pulse measurements will be assessed in the semi-recumbent 
position with a completely automated device. Manual techniques will be used 
only if an automated device is not available.

Blood pressure and pulse 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).

Vital signs (to be taken before blood collection for laboratory tests) will consist 
of 3 blood pressure and pulse measurements (3 consecutive blood pressure and 
pulse readings will be recorded at intervals of at least 1 minute). Each 
measurement will be recorded in the CRF. Triplicate vital signs are required 
only when they occur at the same time point as clinical safety laboratory 
assessments. Vital signs will be taken as a single measurement at all other time 
points. 
8.2.3.
Electrocardiograms

On Day -4, triplicate ECGs will be taken. The ECGs should be recorded over a 
brief (e.g., 5 to 10 minute) recording period. Each measurement will be recorded 
in the CRF.

Single 12-lead ECG will be obtained at other time points as outlined in the SoA 
(Section 1.3) using an ECG machine that automatically calculates the heart rate 
and measures PR, QRS, QT, and QTcF intervals. Refer to Section 7.1.2 for 
QTcF withdrawal criteria and additional QTcF readings that may be necessary.

Twelve-lead ECGs will be performed with the participant in a supine or 
semi-supine position after a rest of at least 10 minutes.

At each time point at which triplicate ECG are required, 3 individual ECG 
tracings should be obtained as closely as possible in succession, but no more

than 2 minutes apart. The full set of triplicates should be completed over a brief 
(e.g., 5 to 10 minute) recording period.
8.2.4.
Clinical Safety Laboratory Assessments

Refer to Appendix 2 for the list of clinical laboratory tests to be performed and 
to the SoA (Section 1.3) 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 CRF. 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 or within 7 days after the last dose of study 
intervention 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 the SoA.
8.2.5.
Suicidal Ideation and Behavior Risk Monitoring
GSK3640254 is not a central nervous system active drug nor is it being developed for a 
neurologic or psychiatric condition. However, given the risk of suicidal ideation 
identified with previous MI GSK3532795, all participants will undergo screening using 
the C-SSRS administered by a clinician (or qualified designee); any positive (abnormal) 
response confirmed by the investigator, will exclude them from participating. A repeat 
assessment will be done at Day 11 and at the end of the treatment phase of the study. In 
case of positive (abnormal) response confirmed by the investigator, the participant will 
discontinue from the trial and the investigator will arrange for urgent specialist 
psychiatric evaluation and management.
As described in Section 7.1.4, new onset suicidal ideation at any time will result in 
immediate discontinuation from the trial and the investigator will arrange for urgent 
specialist psychiatric evaluation and management.
The definitions of behavioral suicidal events used in this scale are based on those used in 
the Columbia Suicide History Form [Posner, 2007]. Questions are asked on suicidal 
behavior, suicidal ideation, and intensity of ideation. Screening visit questions will be in 
relation to lifetime experiences and current experiences (within the past 2 months) and all 
subsequent questioning in relation to the last assessment.

Emergent non-suicidal psychiatric AE Evaluation and Management:

Any Grade 1 or 2 psychiatric AE: A Grade 1 or 2 psychiatric AE may result in 
additional unscheduled visits (in-clinic or at home) as clinically indicated. This 
may include a more in-depth assessment of AE through interview, additional 
unscheduled clinical laboratory samples, and/or imaging. Psychiatric consultation 
may be required at the discretion of the investigator. Any pharmacotherapy should 
be discussed with the medical monitor.

Any Grade 3 or 4 psychiatric AE: As described in Section 7.1.4, a Grade 3 or 4 
psychiatric AE will result in discontinuation from the trial and emergency 
psychiatric evaluation (including potential hospitalization and pharmacotherapy 
as indicated).
8.2.6.
Gastrointestinal Toxicity Evaluation and Monitoring Plan
Preclinical toxicology studies in rats and dogs have suggested a potential for GI-related 
toxicity with GSK3640254. This section provides general guidance to the investigator on 
the evaluation and management of primarily upper GI symptoms (Table 1). The 
investigator may contact the VH/GSK Medical Monitor to discuss evaluation and 
management (including discontinuation of a participant) of any GI symptoms throughout 
the study.
Table 1
Gastrointestinal Toxicity Evaluation and Management
HISTORY
For symptoms of all grades, a thorough history forms the foundation of 
proper evaluation and management. The following are potential 
manifestations of some GI clinical syndromes that may occur (possibly in 
combination) during the clinical study. 
Nausea and Vomiting
The investigator should attempt to identify the etiology of these symptoms (and 
whether it is intraperitoneal, extraperitoneal, medication related, infection related, 
or due to a metabolic disorder [Hasler, 2012]. Medications can cause nausea 
and vomiting acutely. 
Dyspepsia
The investigator should identify the presence of red flags (odynophagia, 
unexplained weight loss, recurrent vomiting, GI bleeding, jaundice, palpable 
mass or adenopathy, or family history of GI malignancy). Symptoms of 
dyspepsia could include early satiety, bloating, or belching. Additionally, atypical 
symptoms of dyspepsia could include: pharyngitis, asthma, bronchitis, 
hoarseness, chest pain, or abdominal pain. 
Other Clinical 
Syndromes
Additional diagnostic criteria for other GI disorders potentially encountered in the 
clinical study are available elsewhere [Rome Foundation, 2018].

PHYSICAL 
EXAMINATION
Physical examination should complement elements obtained from the 
history [Hasler, 2012]. Acutely, the investigator may assess for signs of 
intravascular volume depletion (e.g., orthostasis) and/or aspiration of 
vomitus as appropriate. Abdominal tenderness and guarding may indicate 
inflammation. The presence of fecal blood can indicate mucosal damage 
(e.g., from an ulcer). Complete evaluation of dyspepsia should include an 
oral examination (poor dentition or pharyngeal erythema) and lungs for 
wheezing. 
DIAGNOSTIC 
EVALUATION AND 
MANAGEMENT
A major goal in the diagnostic evaluation of a participant with upper GI 
symptoms is to quickly arrive at a final diagnosis without exposing the 
participant to unnecessary (invasive) testing; investigators should 
exercise good clinical judgment in this regard [Soll, 2009]. A major goal of 
therapy is directed at correcting the underlying identifiable medical or 
surgical abnormalities. Consultation (e.g., gastroenterologist) is 
recommended as clinically indicated.
Grade 1 symptoms
Participants may be treated symptomatically. If participants develop dyspepsia 
alone, generally only limited and direct diagnostic testing should be performed. If 
the participant has dyspepsia they should limit alcohol, caffeine, chocolate, 
tobacco, and eating directly before bedtime. 
Grade 2 symptoms
Diagnostic testing may include but is not limited to the following (as clinically 
indicated):

Serum chemistries and assessment of hemoglobin if not recently performed 

Testing for Helicobacter pylori

Polymerase chain reaction for viruses (e.g., cytomegalovirus)
For participants who are infected with H. pylori, discontinuation from the study is 
necessary. Management should be targeted at addressing the underlying
pathology.
Grade 3 symptoms 1
Diagnostic testing may include but is not limited to the following (as clinically 
indicated):

The testing outlined above in Grade 2

A barium swallow 

Computed tomography scan to identify GI inflammation 

Upper endoscopy with biopsy as indicated (e.g., mucosal injury or the 
presence of red flags)
Management should be targeted at addressing the underlying pathology.
Grade 4 symptoms 1
Diagnostic testing may include but is not limited to the following (as clinically 
indicated):

The testing outlined above in Grade 2 and Grade 3

An acute abdominal series
Initial management can include correction of hemodynamic and electrolyte 
abnormalities as clinically indicated. After stabilization, management should be 
targeted at addressing the underlying pathology.
GI = gastrointestinal.
1
A Grade 4 or related Grade 3 AE: The Investigator will discontinue the participant from the study and perform an 
evaluation/management plan incorporating elements described above.

8.3.
Adverse Events and Serious Adverse Events
The definitions of an AE or SAE can be found in Appendix 6. As described in
Appendix 6, intensity of AEs (and laboratory abnormalities) will be graded using the 
most recent version of the Division of AIDS (DAIDS) grading table at the time of the last 
participant last visit. While the study population will consist of HIV-1 seronegative 
healthy volunteers, the DAIDS criteria will be used in later phase clinical studies 
(Phase 2a and beyond); additionally, the DAIDS criteria have a more conservative 
grading scale relative to other scales (eg. CTCAE v 4.0). Thus, participant safety 
evaluation and monitoring will be more conservative.
The investigator and any qualified 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 intervention or the 
study, or that caused the participant to discontinue the study (see Section 7).
8.3.1.
Time Period and Frequency for Collecting AE and SAE 
Information

All SAEs will be collected from the signing of the ICF until the end of the study 
at the time points specified in the SoA (Section 1.3).

All AEs will be collected from the start of intervention until the end of the study 
at the time points specified in the SoA (Section 1.3).

Medical occurrences that begin before the start of study intervention but after 
obtaining informed consent will be recorded on the Medical History/Current 
Medical Conditions section of the CRF, not the AE section.

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 6. 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 after the conclusion 
of the study participation. 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 
intervention or study participation, the investigator must promptly notify the 
sponsor.
8.3.2.
Method of Detecting AEs and SAEs

The methods of recording, evaluating, and assessing causality of AEs and SAEs 
and the procedures for completing and transmitting SAE reports are provided in 
Appendix 6.

Care will be taken not to introduce bias when detecting an AE and/or SAE. 
Open-ended and nonleading verbal questioning of the participant is the preferred 
method to inquire about AE occurrence.


2018N383291_00
CONFIDENTIAL
208135
41
8.3.3.
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 will be followed until the event is 
resolved, stabilized, otherwise explained, or the participant is lost to follow-up (as 
defined in Section 7.3). Further information on follow-up procedures is given in 
Appendix 6.
8.3.4.
Regulatory Reporting Requirements for SAEs

Prompt notification by the investigator to the sponsor of a SAE is essential so 
that legal obligations and ethical responsibilities towards the safety of 
participants and the safety of a study intervention 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 intervention 
under clinical investigation. The sponsor will comply with country-specific 
regulatory requirements relating to safety reporting to the regulatory authority, 
IRB/IEC, and investigators.

Investigator safety reports must be prepared for suspected unexpected serious 
adverse reactions (SUSAR) according to local regulatory requirements and 
sponsor policy and forwarded to investigators as necessary.

An investigator who receives an investigator safety report describing a 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 CIB and will notify the 
IRB/IEC, if appropriate, according to local requirements.
8.3.5.
Pregnancy

Details of all pregnancies in female participants will be collected after the start 
of study intervention through the end of pregnancy (termination or delivery).

The investigator will collect pregnancy information on any female participant, 
who becomes pregnant while participating in this study and up to 38 days 
post-treatment completion. 

If a pregnancy is reported, the investigator should inform VH/GSK within 
24 hours of learning of the pregnancy and should follow the procedures outlined 
in Appendix 3.

Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, 
stillbirth, congenital anomalies, ectopic pregnancy) are considered SAEs.
8.4.
Treatment of Overdose
For this study, any dose of GSK3640254 or Portia greater than the planned dose within a 
24-hour time period (±2 hours) will be considered an overdose.


2018N383291_00
CONFIDENTIAL
208135
42
VH/GSK does not recommend specific treatment for an overdose. The investigator will 
use clinical judgment to treat an overdose.
In the event of an overdose, the investigator should:
1. Contact the medical monitor immediately.
2. Closely monitor the participant for AE/SAE and laboratory abnormalities until 
GSK3640254 can no longer be detected systemically (at least 5 days).
3. Obtain a plasma sample for PK analysis immediately and through 7 days after the 
date of the last dose of study intervention 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 CRF.
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.
8.5.
Pharmacokinetics

Whole blood samples of approximately 2 mL will be collected for measurement 
of plasma concentrations of GSK3640254 as specified in the SoA (Section 1.3). 

Whole blood samples of approximately 2 mL will be collected for measurement 
of plasma concentrations of EE, and 2 mL will be collected for LNG (i.e., total 
of 4 mL for the 2 analytes) as specified in the SoA (Section 1.3). 

A maximum of 10 samples may be collected at additional time points during the 
study if warranted and agreed upon between the investigator and the sponsor. 
Instructions for the collection and handling of biological samples will be 
provided by the sponsor. The actual date and time (24-hour clock time) of each 
sample will be recorded.

Samples will be used to evaluate the PK of GSK3640254, EE, and LNG. 
Samples collected for analyses of GSK3640254, EE, and LNG plasma 
concentration may also be used to evaluate safety aspects related to concerns 
arising during or after the study.

Once the plasma has been analyzed for GSK3640254, EE, and LNG, any 
remaining plasma may be analyzed for other compound-related metabolites and 
the results reported under a separate protocol.
8.6.
Pharmacodynamics
Venous blood samples of approximately 3.5 mL will be collected for measurement of 
serum progesterone, FSH, and LH at the time points indicated in the SoA (Section 1.3).

Genetics
A 6-mL blood sample for DNA isolation will be collected from participants who have 
consented to participate in the genetics analysis component of the study. Participation is 
optional. Participants who do not wish to participate in the genetic research may still 
participate in the study.
In the event of DNA extraction failure, a replacement genetic blood sample may be 
requested from the participant. Signed informed consent will be required to obtain a 
replacement sample unless it was included in the original consent.
See Appendix 7 for information regarding genetic research. Details on processes for 
collection and shipment and destruction of these samples can be found in the SRM.

STATISTICAL CONSIDERATIONS
9.1.
Statistical Hypotheses
The hypothesis tested by this study:
H0: test /ref < 0.8 or test /ref > 1.25
Ha: 0.8 ≤ test /ref ≤ 1.25
Where test is the geometric least-squares mean for PK parameters of EE/LNG when 
coadministered with GSK3640254 and ref is the geometric least-squares mean for PK 
parameters of EE/LNG when administered alone. If the null hypothesis is not rejected, 
then there is sufficient evidence to suggest an effect of GSK3640254 on the PK of 
EE/LNG; however, if the null hypothesis is rejected, then there is no evidence to suggest 
an effect of GSK3640254 on the PK of EE/LNG. The hypothesis test will be assessed 
using Schuirmann’s 2 one-sided t-test procedure with α=0.05 for each test
(Schuirmann, 1987). Each ratio will be compared to 0.8 and 1.25 as described above. 
Lack of effect is to be demonstrated if the 90% CIs for both LNG and EE lie within 0.8 
and 1.25.

Based upon the historical references [Anderson, 2011; Barr Laboratories, 2000; Butler,
2011; Sevinsky, 2011; Trezza, 2017] a weighted average was obtained as 17.1%, 17.2%, 
13.6%, 13.7% for EE AUC(0-τ), EE Cmax, LNG AUC(0-τ), and LNG Cmax, 
respectively. The largest weighted average CVw for the analytes and parameters was 
17.2%.
The power computation was performed using PASS 15.0.7 procedure for “Equivalence 
Tests for the Ratio of Two Means in a 2×2 Cross-Over Design”: a CVw of 17.2%, Type I 
error of 0.05, true ratio for the means of 0.95, and a required statistical power of 90%. 
The number of evaluable participants required is 19 to achieve at least 90% statistical 
power. For ease of implementation, a total of 25 participants will be enrolled to ensure at 
least 20 provide evaluable data in both test and reference periods.

Appendix 3: Contraceptive Guidance and Collection of 
Pregnancy Information
10.3.1.
Definitions:
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming post-menopausal 
unless permanently sterile (see below).
If fertility is unclear (e.g., amenorrhea in adolescents or athletes) and a menstrual cycle 
cannot be confirmed before first dose of study intervention, additional evaluation should 
be considered.
Women in the following categories are not considered WOCBP
1. Premenarchal
2. Premenopausal female with 1 of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy

Documented bilateral tubal ligation
For individuals with permanent infertility due to an alternate medical cause other 
than the above, (e.g., Müllerian agenesis, androgen insensitivity), investigator 
discretion should be applied to determining study entry.
Note: Documentation can come from the site personnel’s review of the 
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 FSH level in the postmenopausal range may be used to confirm a 
postmenopausal state in women not using hormonal contraception or 
hormonal replacement therapy. However, in the absence of 12 months of 
amenorrhea, confirmation with more than one FSH measurement 
(>40 IU/L or mIU/mL) is required.

Contraception Guidance:
CONTRACEPTIVES ALLOWED DURING THE STUDY INCLUDE:
1.
Participants who have been taking oral contraceptives prior to study entry should continue their 
current regimen until check-in to the clinic for the run-in period.
2.
Participants must use Portia for the duration of the run-in and treatment periods.
3.
Participants must agree to use an additional method of contraception from the list of 
contraceptive methods below for the run-in period, treatment period, and for 28 days after the 
last dose of study intervention:

Non hormonal Intrauterine device 

Bilateral tubal occlusion

Male partner sterilization with documentation of azoospermia prior to the female subject's 
entry into the study, and this male is the sole partner for that subject. The documentation 
on male sterility can come from the site personnel’s: review of subject’s medical records, 
medical examination and/or semen analysis, or medical history interview provided by her 
or her partner.

Sexual abstinence. Note: Sexual abstinence is considered a highly effective method only if 
defined as refraining from penile-vaginal intercourse on a long term and persistent basis
when this is their preferred and usual lifestyle. 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.

For the 28 days after study exit, women may resume oral contraceptives but double 
barrier methods (a combination of male condom with either cervical cap, 
diaphragm, or sponge with spermicide) must be used in addition.
10.3.3.
Collection of Pregnancy Information:
Female Participants who become pregnant

The 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 VH/GSK
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 VH/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 intervention by the investigator, will be reported 
to VH/GSK as described in Appendix 6. 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 
intervention or be withdrawn from the study.

Appendix 6: Adverse Events: Definitions and Procedures for 
Recording, Evaluating, Follow-up, and Reporting
10.6.1.
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 intervention, whether or not considered related to 
the study intervention.

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 intervention.
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 sign 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 intervention administration even 
though it may have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected DDI.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
intervention 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.
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 condition.

Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 
leads to the procedure is the AE.


2018N383291_00
CONFIDENTIAL
208135
63

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.
10.6.2.
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:
Results in death
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.
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.
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.
Is a congenital anomaly/birth defect


2018N383291_00
CONFIDENTIAL
208135
64
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.
10.6.3.
Recording and Follow-Up of 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 VH/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 VH/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 VH/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 investigator will make an assessment of intensity for each AE and SAE reported 
during the study using the DAIDS grading table Version 2.1, July 2017
(https://rsc.niaid.nih.gov/sites/default/files/daidsgradingcorrectedv21.pdf) and assign it to 
1 of the following categories: 

Mild: no or minimal interference with usual social & functional activities 

Moderate: greater than minimal interference with usual social and functional 
activities

Severe: inability to perform usual social and functional activities. An AE that is 
assessed as severe should not be confused with an SAE. Severe is a category utilized 
for rating the intensity of an event; and both AE and SAE can be assessed as severe.


2018N383291_00
CONFIDENTIAL
208135
65

Life Threatening: inability to perform basic self-care functions
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 intervention 
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 intervention 
administration will be considered and investigated.

The investigator will also consult the CIB 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 
minimal information to include in the initial report to VH/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 1 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 VH/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 VH/GSK with a copy of any 
post-mortem findings including histopathology.

New or updated information will be recorded in the originally completed CRF.


2018N383291_00
CONFIDENTIAL
208135
66

The investigator will submit any updated SAE data to VH/GSK within 24 hours of 
receipt of the information.
10.6.4.
Reporting of SAE to VH/GSK
SAE Reporting to GSK via Electronic Data Collection Tool

The primary mechanism for reporting an SAE to VH/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 electronic CRF (e.g., check review box, signature, etc.) of review and verification 
of the relationship of each SAE to study intervention/study participation (causality) 
within 72 hours of SAE entry into the electronic CRF.

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 site can report this information on a paper SAE form (see 
next section) or to the medical monitor by telephone.

Contacts for SAE reporting can be found in the SRM.
SAE Reporting to VH/GSK via Paper CRF

Facsimile transmission of the SAE paper CRF is the preferred method to transmit 
this information to the medical monitor.

In rare circumstances and in the absence of facsimile equipment, notification by 
telephone is acceptable with a copy of the SAE data collection tool sent by overnight 
mail or courier service.

Initial notification via telephone does not replace the need for the investigator to 
complete and sign the SAE CRF pages within the designated reporting time frames.

Contacts for SAE reporting can be found in SRM.

Appendix 7: Genetics
USE/ANALYSIS OF DNA

Genetic variation may impact a participant’s response to study intervention, 
susceptibility, severity, and progression of disease. Variable response to study 
intervention 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 IRB/IEC allow, a blood sample will be 
collected for DNA analysis.

DNA samples will be used for research related to GSK3640254 or HIV and 
related diseases. They may also be used to develop tests/assays including 
diagnostic tests related to GSK3640254 or HIV MIs and HIV. 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 GSK3640254 or study interventions 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 GSK3640254 (or study 
interventions of this class) or HIV continues but no longer than 15 years after 
the last participant’s last visit or other period as per local requirements.

o
Check-in: Day -4
o
Run-in Period: Portia (0.3 mg EE/0.15 mg LNG) once daily (QD) 
(Days -3 to -1)
o
Treatment Period: Portia (0.03 mg EE/0.15 mg LNG) QD on Days 1 to 
10 (Treatment A), followed by Portia (0.03 mg EE/0.15 mg LNG) QD

Time & 
Events

Refer to Appendix 1: Schedule of Activities
Treatment 
Assignment

This is an open-label study. All eligible participants will receive the same treatment.
Interim 
Analysis

No interim analysis is planned for this study
[1] The “Washout” period of this study should be called “Follow Up” as there is only one treatment period. See 208135 
Protocol Clarification dated 10-June-2019
2.4.
Statistical Hypotheses
The hypothesis tested by this study:


CONFIDENTIAL
208135
8
H0: test /ref < 0.8 or test /ref > 1.25
Ha: 0.8 ≤ test /ref ≤ 1.25
Where test is the geometric least-squares mean for PK parameters of EE/LNG when 
coadministered with GSK3640254 and ref is the geometric least-squares mean for PK 
parameters of EE/LNG when administered alone. If the null hypothesis is not rejected, 
then there is sufficient evidence to suggest an effect of GSK3640254 on the PK of 
EE/LNG; however, if the null hypothesis is rejected, then there is no evidence to suggest 
an effect of GSK3640254 on the PK of EE/LNG. The hypothesis test will be assessed 
using Schuirmann’s 2 one-sided t-test procedure with α=0.05 for each test
(Schuirmann, 1987). Each ratio will be compared to 0.8 and 1.25 as described above. 
Lack of effect is to be demonstrated if the 90% CIs for both LNG and EE lie within 0.8 
and 1.25.

Protocol Deviations
Important protocol deviations (including deviations related to study inclusion/exclusion 
criteria, conduct of the trial, participant management or participant assessment) will be 
summarized and listed.
Protocol deviations will be tracked by the study team throughout the conduct of the study 
in accordance with the Protocol Deviation Management Plan. The “significant” protocol 
deviation in the Protocol Deviation Management Plan is equivalent to “important” 
protocol deviations.

o Data will be reviewed prior to freezing the database to ensure all significant
deviations and deviations which may lead to exclusion from the analysis are 
captured and categorised on the protocol deviations dataset. 
o This dataset will be the basis for the summaries and listings of protocol 
deviations.
A separate listing of all inclusion/exclusion criteria deviations will also be provided. This 
listing will be based on data as recorded on the inclusion/exclusion page of the electronic 
case record form (eCRF).

Reporting Standards
General

The current GSK Integrated Data Standards Library (IDSL) will be applied for reporting, unless 
otherwise stated (IDSL Standards Location: 
https://spope.gsk.com/sites/IDSLLibrary/SitePages/Home.aspx):

4.03 to 4.23: General Principles

5.01 to 5.08: Principles Related to Data Listings

6.01 to 6.11: Principles Related to Summary Tables

7.01 to 7.13: Principles Related to Graphics 

Do not include participant level listings in the main body of the GSK Clinical Study Report. All 
participant level listings should be located in the modular appendices as ICH or non-ICH listings.
Formats

All data will be reported according to the actual treatment the participant received unless 
otherwise stated.

GSK IDSL Statistical Principles (5.03 & 6.06.3) for decimal places (DP’s) will be adopted for 
reporting of data based on the raw data collected, unless otherwise stated.

Numeric data will be reported at the precision collected on the eCRF.

The reported precision from non eCRF sources will follow the IDSL statistical principles but may be
adjusted to a clinically interpretable number of DP’s.
Planned and Actual Time

Reporting for tables, figures, and formal statistical analyses:

Planned time relative to dosing will be used in figures, summaries, statistical analyses and 
calculation of any derived parameters, unless otherwise stated.

The impact of any major deviation from the planned assessment times and/or scheduled visit 
days on the analyses and interpretation of the results will be assessed as appropriate.

Reporting for Data Listings: 

Planned and actual time relative to study drug dosing will be shown in listings (Refer to IDSL 
Statistical Principle 5.05.1).


Unscheduled or unplanned readings will be presented within the participant’s listings. 

Visits outside the protocol defined time-windows (i.e. recorded as protocol deviations) will be 
included in listings but omitted from figures (mean figures only for PK concentrations), 
summaries, and statistical analyses (excluding statistical analyses of PK parameters).
Unscheduled Visits

Unscheduled visits will not be included in summary tables except for determining the worst-case 
values.

Unscheduled visits will not be included in figures.

All unscheduled visits will be included in listings.

Descriptive Summary 
Statistics, Graphical 
Displays and Listings
Refer to IDSL PK Display Standards.
Refer to IDSL Statistical Principle 6.06.1.
For continuous data:

NQs at the beginning of a participant profile (i.e. before the first incidence of a 
measurable concentration) are deemed to be zero as it is assumed that in this 
circumstance no drug is yet measurable in the blood.

For NQs at the end of the participant profile (i.e. after the last incidence of a 
measurable concentration);

for individual plots and pharmacokinetic analyses these are dropped (set 
to missing) as they do not provide any useful information (and can 
erroneously indicate that absolutely no drug is present)

for summary statistics, these are set to 0 (to avoid skewing of the 
summary statistics)

Individual NQs which fall between two measurable concentrations are set to 
missing (individual values of this nature are assumed to be an anomaly)
If two or more NQ values occur in succession between measurable concentrations, 
the profile will be deemed to have terminated at the last measurable concentration 
prior to these NQs. For the purpose of individual participant plots, these NQs will be 
set to 0, and the subsequent measurable concentrations will be retained. For the 
derivation of pharmacokinetic parameters, these NQs and any subsequent 
measurable concentrations will be omitted (set to missing).
Note: Concentration values will be imputed as per GUI_51487 for descriptive 
summary statistics/analysis and summarized graphical displays only.

The worst finding/interpretation associated with multiple measurements as the finding/interpretation 
for that time point.

Participants having both High and Low values for Normal Ranges at any post-baseline visit for safety 
parameters will be counted in both the High and Low categories of “Any visit post-baseline” row of 
related summary tables. This will also be applicable to relevant Potential Clinical Importance 
summary tables.
Study Day

Calculated as the number of days from Dose Date on Day 1:

Assessment Date = Missing 
  → Study Day = Missing 

Assessment Date < Dose Date on Day 1 
  → Study Day = Assessment Date –Dose Date on Day 1

Assessment Date >= Dose Date on Day 1
  → Study Day = Assessment Date – Dose Date on Day 1 + 1
Period Day

Calculated as the number of days from First Dose Date for the respective period:

Assessment Date = Missing 
  → Period Day = Missing 

Assessment Date < Dose Date on Day -3
  → Period Day = Assessment Date – Dose Date on Day -3

Dose Day on Day -3 <= Assessment Date < Dose Date on Day 1
  → Period Day = Assessment Date – Dose Date on Day -3 + 1

Dose Date on Day 1 <= Assessment Date < First Dose Date on Day 11 
  →Period Day = Assessment Date – Dose Date on Day 1 + 1

Assessment Date >= First Dose Date on Day 11 
  →Period Day = Assessment Date – First Dose Date on Day 11 + 1

Age

GSK standard IDSL algorithms will be used for calculating age where birth date will be imputed as 
follows:
o
Any participant with a missing day will have this imputed as day ‘15’.
o
Any participant with a missing day and month will have this imputed as ‘30th June’.

Birth date will be presented in listings as ‘YYYY’.

Premature Withdrawals
Element
Reporting Detail
General

Participant study completion (i.e. as specified in the protocol) was defined as the 
participant had completed all phases of the study including the final date on which data 
were or are expected to be collected. 

Withdrawn participants were not replaced in the study.

All available data from participants who were withdrawn from the study will be listed 
and all available planned data will be included in summary tables and figures, unless 
otherwise specified.
11.5.2.
Handling of Missing Data
Element
Reporting Detail
General

Missing data occurs when any requested data is not provided, leading to blank fields 
on the collection instrument:
o
These data will be indicated by the use of a “blank” in participant listing displays. 
Unless all data for a specific visit are missing in which case the data is excluded 
from the table. 
o
Answers such as “Not applicable” and “Not evaluable” are not considered to be 
missing data and should be displayed as such.
Outliers

Any participants excluded from the summaries and/or statistical analyses will be 
documented along with the reason for exclusion in the clinical study report.
11.5.2.1.
Handling of Missing and Partial Dates
Element
Reporting Detail
General

Partial dates will be displayed as captured in participant 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 2: 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.
Concomitant 
Medications

Partial dates for any concomitant medications recorded in the eCRF will be imputed 
using the following convention:
o
If the partial date is a start date, a '01' will be used for the day and 'Jan' will be 
used for the month
o
If the partial date is a stop date, a '28/29/30/31' will be used for the day (dependent 
on the month and year) and 'Dec' will be used for the month.

The recorded partial date will be displayed in listings.

Laboratory Values
Laboratory abnormalities will be graded according to the DAIDS grading table Version 2.1, July 2017. Laboratory results are converted to 
use SI units; only the numeric part of the criteria will be used. If for a laboratory parameter there are multiple grades sharing the same 
criteria, the maximum grade will be used.
