Keywords: pharmacokinetic pediatric Tafenoquine Plasmodium vivax Malaria G6PD deficiency
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 60
Healthy volunteers: no

Brief summary:
This is a prospective, open-label, multicenter, non-comparative, single arm study of pediatric subjects with Plasmodium vivax (P. vivax) malaria, aged 6 months to \<16 years of age. A total of 60 subjects will be enrolled. Potential subjects who are slide-positive for P. vivax will be started by the site on chloroquine (CQ) per local/national guidelines. Sites will have up to 48 hours to obtain consent. Once full consent is provided, all subjects will be screened and, if eligible, receive Tafenoquine (TQ), given as a single dose on Day 1. All study medication should be taken with food. After the treatment period, subjects will attend up to 7 follow-up visits through Day 120 (Days 3, 8, 15, 29, 60, 90 and 120). The main cohort will consist of subjects aged \>=2 years to \<16 years with no restriction on gender. Subjects will be dosed according to four weight bands. Within the total of 60 enrolled pediatric subjects, a second cohort of up to 6 infants aged \>=6 months to \<2 years (weighing \>=5 kilogram \[kg\]) will be recruited following completion of a planned first interim analysis. An interim analysis will be conducted once sufficient data from 16 subjects is available to assess pharmacokinetic (PK) and safety parameters. If needed, a second interim analysis will be conducted after a total of 32 subjects have enrolled. The primary objective of this PK bridging study is to adequately characterize the systemic TQ exposure in the pediatric population in order to identify appropriate doses that achieve a similar exposure to that of the TQ adult dose of 300 milligram (mg).

Detailed description:

Arms:
arm 1: Subjects with weight band of \>=5 to \<=10 kilogram (kg) will receive 50 mg tafenoquine on Day 1. Subject may receive CQ per local/national guidelines. arm 2: Subjects with weight band of \>10 to \<=20 kg will receive 100 mg tafenoquine on Day 1. Subject may receive CQ per local/national guidelines. arm 3: Subjects with weight band of \>10 to \<=20 kg will receive 150 mg tafenoquine on Day 1. Subject may receive CQ per local/national guidelines. arm 4: Subjects with weight band of \>20 to \<=35 kg will receive 200 mg tafenoquine on Day 1. Subject may receive CQ per local/national guidelines. arm 5: Subjects with weight band of \>35 kg will receive 300 mg tafenoquine on Day 1. Subject may receive CQ per local/national guidelines.

PROTOCOL SYNOPSIS FOR STUDY TAF113577
Rationale
Infants, children and adolescents account for a significant proportion of P. vivax
infections worldwide. In regions with high intensity of transmission, the incidence of 
P. vivax malaria peaks in subjects before the age of 2 years while in low intensity 
transmission areas P. vivax infection and disease occurs in all pediatric age groups.
Many similarities exist in the clinical manifestations of P. vivax infection among adult 
and pediatric populations. In India, fever and chills were the most commonly reported 
clinical symptoms in both populations. Tender splenomegaly and anemia are also 
common findings in patients with chronic or recurrent disease caused by P. vivax. As in 
adults, relapses frequently occur months to years after the initial infection unless 
appropriate treatment to eradicate the hepatic phase of the parasite is administered.  Since 
severe anemia is a relatively common consequence of P. vivax infection in younger 
children, pediatric P. vivax patients are at risk of blood transfusion-associated infections 
(e.g., HIV, hepatitis B and C) and are at an increased probability of death from the 
clinical consequences of the anemia.
A strong exposure-efficacy response relationship has been identified for tafenoquine 
(TQ) in adult patients in part 1 of Study TAF112582.  A clinically relevant systemic 
exposure (AUC) of TQ, 56.4 µg.h/mL, was derived using a Classification and Regression 
Tree (CART) analysis.  Subjects with TQ exposure ≥ 56.4 µg.h/mL were likely to have 
significantly lower relapses compared to subjects with < 56.4 µg.h/mL. Based on 
simulations, the probability of being recurrence-free at 6 months was 52% (95% CI: 44% 
to 61%) in subjects with a TQ AUC < 56.4 μg.h/mL compared to 85% (95% CI: 80% to 
90%) in subjects with a TQ AUC ≥ 56.4 µg.h/mL. Additionally, 93% of subjects on the 
300mg dose had a predicted AUC that exceeded 56.4 μg.h/mL. 
The currently proposed doses for the pediatric study are derived from a population 
pharmacokinetic (PK) model built using the systemic TQ exposure data from adults in 
part 1 of Study TAF112582. The population PK model incorporated allometric scaling 
for bodyweight. Based on this population PK model, a 60 kg adult on 300mg dose will 
have a median AUC(0-∞) of 96 μg.h/mL (95% prediction interval 55-162 μg.h/mL). The 
proposed starting doses for this pediatric study are predicted to achieve a similar target 
exposure after accounting for the subjects’ bodyweight. The lower prediction limit 
AUC(0-∞)  of 55 μg.h/mL from the model is also consistent with the cut-off obtained 
from the CART analysis (AUC(0-∞) of 56.4 μg.h/mL) and therefore provides a high 
degree of confidence in the efficacy in the pediatric population using this PK bridging 
approach.
Therefore the primary objective of this study is to generate systemic exposure data to 
enable the modelling of the pharmacokinetics of TQ in infants, children and adolescents 
with P. vivax to identify and recommend doses for pediatric subjects that achieve similar 
TQ AUC (0-∞) to the selected adult dose of 300 mg.  If achieved, this will provide a 
bridge for dose selection with extrapolation of the adult efficacy data to infants, children
and adolescents aged 6 months to <16 years.  In addition, the safety and the clinical and

parasitological efficacy of TQ will be studied in pediatric subjects receiving TQ and 
chloroquine (CQ).

Overall Design

TAF113577 is a prospective, open-label, multicenter, non-comparative, single-
arm study. All subjects will receive CQ and open-label TQ.

Potential subjects can be identified, pre-screened, and begin off-study treatment 
with CQ, after which sites will have up to 48 hours to obtain full consent/assent, 
as applicable.  Upon consent, subjects will be treated with tafenoquine on Day 1, 
then attend seven follow-up visits (Days 3, 8, 15, 29, 60, 90 and 120). The total 
follow-up period will be 120 days.

Subjects must have a blood smear that is positive for P. vivax at pre-screening.  
Blood smears will be taken at Day 1 (screening) and at Day 8 to confirm the 
parasite has cleared.  Additional parasitological assessments will be conducted on 
visit Days 29, 60, 90 and 120.

At the Day 1 visit subjects will be screened for G6PD deficiency by a quantitative 
assay and the result will be determined as a percentage of the predetermined 


2014N207627_03

TAF113577
12
median enzyme activity of the site.  All subjects must have a minimum G6PD 
assay value of 70% to be enrolled.

A subject is considered to have completed the study if they attend all treatment 
and follow-up visits. A PK evaluable subject is defined as one with a minimum of 
one PK sample from Days 3, 15, 29 and 60.

The final safety analysis will take place when all 60 enrolled subjects have 
completed the study. 

Safety data will be collected on all subjects who receive a dose of TQ.
Treatment Arms and Duration
In this single-arm study, potential subjects who are slide-positive for P. vivax will be 
started by the site on CQ per local/national guidelines.  Sites will have up to 48 hours to 
obtain consent.  Once full consent is provided, all subjects will be screened and, if 
eligible, receive TQ, given as a single dose on Day 1.  All study medication should be 
taken with food.  After the treatment period, subjects will attend up to 7 follow-up visits 
through Day 120.
Type and Number of Subjects
Approximately 240 subjects aged <16 years with P. vivax malaria will be screened to 
achieve 60 completed subjects.  A subject is considered to have completed the study if 
they attend all treatment and follow-up visits. A PK evaluable subject is defined as one 
with a minimum of one PK sample from Days 3, 15, 29 and 60, with accurate dosing and
sample time histories.
Initially, subjects ≥2 years to <16 years of age will be enrolled into the study.  
Recruitment to an additional cohort of infants aged ≥6 months to <2 years (weighing ≥5 
kg) may begin following completion of the first interim analysis.  This lower age cohort 
are included as part of the 60 completed subjects.
Analysis
There are no hypotheses tested in this study.  The study is designed to characterize TQ 
exposures in pediatric subjects.  A population PK modelling and simulations-based 
approach was utilized to support appropriate study sample size and PK sampling times 
for the proposed population PK bridging study.  Based on these simulations, a sample 
size of 16 subjects and a sparse sampling scheme of four time points per subject are 
considered sufficient for the evaluation of the primary PK objective of estimating TQ 
apparent systemic clearance (CL) and thus exposure [AUC(0-∞) = Dose/CL] within each 
weight band in pediatric subjects aged ≥2 years to <16 years.  Up to two interim analyses 
(at 16 and 32 subjects) have been planned so that sparse PK sampling may be stopped at 
the earliest opportunity, although all remaining subjects recruited into the study will have 
a minimum of two PK samples taken. Recruitment will continue for safety data 
accumulation.

The primary population PK model-based analysis to be performed will borrow some 
information from the adult model as appropriate. The sparse sampling in pediatric 
subjects is insufficient to independently characterize the absorption phase. Consequently 
the information about absorption from the adult model will be used as prior information 
to feed into the pediatric PK model with the assumption that the absorption processes are 
similar in adults and pediatric subjects.  The pediatric population PK model will aim to 
reliably estimate the TQ clearance and thus the exposures in pediatric population.  The 
clearance estimate for each subject generated from the model-based analysis will be used 
to determine the subject’s TQ AUC(0-∞) [AUC(0-∞) = Dose/CL].

INTRODUCTION
Tafenoquine (TQ; SB-252263 and WR238605) is a novel 8-aminoquinoline anti-malarial 
drug being co-developed by GlaxoSmithKline and the Medicines for Malaria Venture 
with the assistance and historic support of the Walter Reed Army Institute of Research.  It 
is a synthetic analogue of primaquine (PQ) and is currently being developed for the 
radical cure of acute Plasmodium vivax malaria, to be administered as a single dose along 
with standard doses of the anti-malarial chloroquine (CQ).  Of note, TQ possesses 
activity against all stages of the Plasmodium lifecycle, including the dormant P. vivax
hypnozoite.
2.1.
Study Rationale
2.1.1.
Pediatric P. vivax Malaria
Infants, children and adolescents account for a significant proportion of P. vivax
infections worldwide. In regions with high intensity of transmission, the incidence of 
P. vivax malaria peaks in subjects before the age of 2 years while in low intensity 
transmission areas P. vivax infection and disease occurs equally in all pediatric age 
groups [World Global Malaria Programme, 2013; Anstey, 2012].  Congenital P. vivax
infection does not require treatment with radical cure drugs, apparently because
sporozoites do not enter the fetal circulation, preventing the development of hypnozoites 
in the fetus [Menendez, 2007]. By contrast, vector-borne P. vivax infections in the 
pediatric population behave broadly similarly to adults and thus treatment is required to 
prevent relapses from hypnozoites. 
As transmission rates are low in most regions where P. vivax is prevalent, affected 
populations do not achieve high levels of immunity (or premunition) to this parasite and 
people of all ages are at risk of infection [Crawley, 2010]. Many similarities exist in the 
clinical manifestations of P. vivax infection among adult and pediatric populations. For 
example, in a study of adult and pediatric patients with vivax malaria in India, fever and 
chills were the most commonly reported clinical symptoms in both populations [Singh,
2013a]. Tender splenomegaly and anemia are also common findings in patients with 
chronic or recurrent disease caused by P. vivax. As in adults, relapses frequently occur 
months to years after the initial infection unless appropriate treatment to eradicate the 
hepatic phase of the parasite is administered [Summer, 2005]. 
Among patients with severe disease, the most frequent manifestations for both adults and 
children are severe anemia and acute respiratory distress. Less commonly, cerebral 
malaria, kidney injury, shock, and coagulopathy have also been reported [Baird, 2012].  
P. vivax infection may also present with thrombocytopenia, which is a well-documented 
and frequent complication in both adult and pediatric patients with vivax malaria 
[Rodriguez-Morales, 2014], occurring with similar frequency in both age groups. In a 
review of 9 studies of patients with vivax malaria, thrombocytopenia was reported in 
22.5% to 93.3% of adults [George, 2010; Kashinkunti, 2013; Kochar, 2009; Srivastava, 
2011], and 22.2% to 95.6% of children [Mahgoub, 2012; Rodriguez-Morales, 2006;

Since severe anemia is a relatively common consequence of P. vivax infection in younger 
children, pediatric P. vivax patients are at risk of blood transfusion-associated infections 
(e.g., HIV, hepatitis B and C) and are at an increased probability of death from the 
clinical consequences of the anemia itself; however, the risks of severe disease and case 
fatality rates for P. vivax infection varies and have not been firmly established. In 
addition, there is accumulating evidence that P. vivax malaria impairs weight gain and 
growth as well as school performance, underlying the chronic, insidious impact that 
repeated relapses have on individuals and communities.
Besides parasite and host-related factors, severe anemia and acute renal failure could 
result from severe hemolysis in glucose-6-phosphate dehydrogenase (G6PD) deficient 
children being treated with PQ.  Although this is rarely described in the literature under-
reporting is likely to occur.  Fortunately diagnosis of G6PD deficiency in the pediatric 
population is identical to that in adults. Normal G6PD activity has been found to be 
higher in newborns (<7 days) than in adults but this does not affect diagnosis of complete 
G6PD deficiency, as G6PD deficient newborns show identical low levels to those of 
deficient adults but further complicates identification of heterozygote individuals.
2.1.2.
Adult Tafenoquine Program and Design Rationale
A phase III program is ongoing to study TQ in adult subjects (≥16 years of age) with 
P. vivax malaria.  This program is comprised of two studies:
1. Study TAF112582 [GlaxoSmithKline Document Number RM2010/00052/04] is a 
seamless phase II/III study in which the phase II portion has completed and an 
efficacious dose of TQ with a clinically acceptable safety profile has been 
selected; a single 300 mg dose. The phase III portion of TAF112582 will test the 
efficacy and safety of the selected TQ/CQ regimen in the radical cure of P. vivax
malaria.
2. Study TAF116564 [GlaxoSmithKline Document Number 2012N152563_01] will 
characterize the incidence of hemolysis with TQ/CQ, and compare this to the 
incidence of hemolysis with PQ/CQ. In particular, a subset of adult female 
subjects will be enrolled that display a moderate deficiency in G6PD activity 
(G6PD heterozygous deficiency; susceptible to being misclassified as having 
“normal” G6PD activity by G6PD tests) so that the potential for hemolysis can be 
studied using the selected TQ/CQ regimen.
A strong exposure-efficacy response relationship has been identified for TQ in adult 
patients in part 1 of Study TAF112582.  A clinically relevant systemic exposure (AUC) 
of TQ, 56.4 µg.h/mL, was derived using a Classification and Regression Tree (CART) 
analysis.  Subjects with TQ exposure ≥ 56.4 µg.h/mL were likely to have significantly 
lower relapses compared to subjects with < 56.4 µg.h/mL. Based on simulations, the 
probability of being recurrence-free at 6 months was 52% (95% CI: 44% to 61%) in 
subjects with a TQ AUC < 56.4 μg.h/mL compared to 85% (95% CI: 80% to 90%) in 
subjects with a TQ AUC ≥ 56.4 µg.h/mL. Additionally, 93% of subjects on the 300mg 
dose had a predicted AUC that exceeded 56.4 μg.h/mL.

Therefore the primary objective of this study is to generate systemic exposure data to 
enable the modelling of the PK of TQ in infants, children and adolescents with P. vivax to 
identify and recommend doses for pediatric subjects that achieve similar TQ AUC (0-∞) 
to the selected adult 300 mg dose.  If achieved, this will provide a bridge for dose 
selection with extrapolation of the adult efficacy data to children.  In addition, the safety 
and the clinical and parasitological efficacy of TQ will be studied in pediatric subjects 
receiving TQ/CQ.
2.2.
Brief Background
Tafenoquine has been shown to have an acceptable safety profile in the treatment and 
prevention of plasmodial infections in pre-clinical models and during Phase I, II and III 
clinical studies in >4000 subjects aged ≥16 years old.
All members of the 8-aminoquinoline class of drugs, including TQ and PQ, induce 
hemolysis in subjects with G6PD deficiency. G6PD is a housekeeping enzyme 
responsible for protection against oxidant stress. The effects of oxidant stress in subjects 
with G6PD deficiency are most apparent in red blood cells.  Tafenoquine is thus being 
developed for treatment of patients with sufficient levels of G6PD enzyme activity.  
Tafenoquine has a long half-life, and as such can be administered as a single oral dose.  
This is in contrast to PQ, which requires 14 days dosing.  It must be determined if 
improved compliance with TQ could also lead to improved clinical outcomes.  
Tafenoquine should have no clinically significant side effects that will restrict its use as a 
first line agent in treatment of P. vivax malaria when used in combination with a G6PD 
test and recommended therapies to treat the blood stages of infection.

OBJECTIVES AND ENDPOINTS
Objectives
Endpoints
Primary

To evaluate the pharmacokinetics (PK) 
of tafenoquine in children and 
adolescents aged ≥2 years to <16 years 
(weighing ≥5 kg) with P. vivax in order 
to identify appropriate doses that 
achieve a similar exposure to that of the 
tafenoquine adult dose of 300 mg.

AUC(0-∞) of TQ by weight band from 
a population PK model in pediatric 
subjects aged ≥2 years to <16 years 
(weighing ≥5 kg).
Secondary

To assess the safety of tafenoquine 
when administered to pediatric 
subjects with P. vivax malaria.

Description of safety data in the study 
population. Key safety endpoints of 
interest are:
Gastrointestinal tolerability, and
Clinically relevant drops in 
hemoglobin.
Additionally, the incidence and 
severity of adverse events and 
abnormal laboratory observations.

To assess the clinical and 
parasitological efficacy of tafenoquine 
as a radical cure for pediatric subjects 
with P. vivax malaria when co-
administered with chloroquine.

Recurrence-free efficacy at four 
months post-dosing.

To assess the PK of tafenoquine in 
infants aged ≥6 months to <2 years 
(weighing ≥5 kg) with P. vivax (if data 
permit)

AUC(0-∞) of TQ by weight band from 
a population PK model in infants aged 
≥6 months to <2 years (weighing ≥5
kg).
With regard to the secondary efficacy endpoint, it should be noted that it is not possible 
to determine if a subject's recurrence of malaria is a relapse (liver stage treatment failure)
or a re-infection (i.e., new infection), even when using current genetic techniques.  
Likewise, it is not possible to determine if a recurrence is a re-infection or recrudescence 
(blood stage treatment failure).  For the purposes of this protocol, the term ‘recurrence’ 
will be used to represent any type of malaria treatment failure.  Recurrence is defined as a 
positive blood smear with or without vivax malaria symptoms.

STUDY DESIGN

TAF113577 is a prospective, open-label, multicenter, non-comparative, single-
arm study. All subjects will receive CQ and open-label TQ.

Potential subjects can be identified, pre-screened, and begin off-study treatment 
with CQ, after which sites will have up to 48 hours to obtain full consent/assent, 
as applicable.  Upon consent, subjects will be treated with tafenoquine on Day 1, 
then attend seven follow-up visits (Days 3, 8, 15, 29, 60, 90 and 120). The total 
follow-up period will be 120 days.

During the follow-up period, sites have the option of performing non-PK visits 
(Days 8, 90 and 120) at the subject’s home.

Subjects must have a blood smear that is positive for P. vivax at pre-screening.  
Blood smears will be taken at Day 1 (screening) and at Day 8 to confirm the 
parasite has cleared.  Additional parasitological assessments will be conducted on 
visit Days 29, 60, 90 and 120.

At the Day 1 visit subjects will be screened for G6PD deficiency by a quantitative 
assay and the result will be determined as a percentage of the predetermined 
median enzyme activity of the site.  All subjects must have a minimum G6PD 
assay value of 70% to be enrolled.

A total of 60 pediatric subjects will be enrolled.  The main cohort will consist of 
subjects aged ≥2 years to <16 years with no restriction on gender. Subjects will be 
dosed according to four weight bands.

Within the total of 60 enrolled pediatric subjects, a second cohort of up to 6
infants aged ≥6 months to <2 years (weighing ≥5 kg) may be recruited following 
completion of a planned first interim analysis (see below).

An interim analysis will be conducted once sufficient data from 16 subjects is 
available to assess PK and safety parameters.  If needed, a second interim analysis 
may be conducted after a total of 32 subjects have enrolled.  The primary analysis 
population will be the PK evaluable population.

A subject is considered to have completed the study if they attend all treatment 
and follow-up visits. A PK evaluable subject is defined as one with a minimum of 
one PK sample from Days 3, 15, 29 and 60.

The final safety analysis will take place when all 60 enrolled subjects have 
completed the study. 

A population PK model will be used to estimate the clearance and thus exposure 
of TQ for each of the weight bands in the main cohort [AUC(0-∞) = 
Dose/Clearance (CL)].

4.2.
Treatment Arms and Duration
In this single-arm study, potential subjects who are slide-positive for P. vivax will be 
started by the site on CQ per local/national guidelines.  Sites will have up to 48 hours to 
obtain consent.  Once full consent is provided, all subjects will be screened and, if 
eligible, receive TQ, given as a single dose on Day 1.  All study medication should be 
taken with food.  After the treatment period, subjects will attend up to 7 follow-up visits 
through Day 120.
Due to the large variation in weight for the same age anticipated across various countries, 
pediatric subjects will have TQ dosed by weight instead of by age. This approach with 
weight based dosing is also more relevant since various enzymatic processes that may be 
involved in drug metabolism generally reach adult maturation levels post 6 months of 
age. The current study does not enrol subjects less than 6 months of age. TQ doses 
within weight bands were selected by using a population PK modelling and simulation 
approach based on adult data and incorporation of allometric scaling (see Appendix 8, 
Section 12.8, Tafenoquine Pediatric Dose Extrapolation). Based on these simulations
there will be four weight bands of ≥5 to ≤10 kg, >10 to ≤20 kg, >20 to ≤35 kg and >35 kg 
with proposed starting doses for pediatrics from 100 to 300 mg TQ (see Section 4.5). 
Enrollment into all weight bands will be conducted in parallel.  Although no minimum 
enrollment is required in any single weight band prior to the interim analyses, efforts will 
be made to enrol subjects across all weight bands.
An interim population PK analysis will be performed once data from 16 subjects is 
obtained (Figure 2).  The TQ clearance estimate (CL) for each subject generated from the 
population model based analysis will be used to determine the subject’s TQ exposure; 
i.e., AUC(0-∞) [AUC(0-∞) = Dose/CL].  The model based pediatric exposure predictions
will be compared to the corresponding adult exposures at the 300mg dose that have been 
shown to be efficacious. If the data is sufficient to make reliable predictions for dose 
recommendations, full PK sampling in the trial will be stopped. If the data are deemed 
insufficient, the PK sampling will continue to collect PK data from another set of 16 
pediatric subjects where after the modelling and simulation activity will be repeated at 
the second interim analysis.  Once the full PK assessments are completed and sufficient 
data is available to reliably characterize pediatric TQ PK, all remaining enrolled subjects 
will provide two PK samples at Day 15 and Day 29 to provide data for the final 
population PK analysis of TQ to be conducted at the end of the study. If during the 
analysis it is realized that exposures are greater than 275 µg.hr/mL, the dosing strategy 
will be revised. Refer to Section 4.6.1 for details.

4.3.
Type and Number of Subjects
Approximately 240 subjects aged <16 years with P. vivax malaria will be screened to 
achieve 60 enrolled subjects.  Initially, subjects ≥2 years to <16 years of age will be 
enrolled into the study.  Recruitment to an additional cohort of infants aged ≥6 months to 
<2 years (weighing ≥5 kg) may begin following completion of the first interim analysis.
A subject is considered to have completed the study if they attend all treatment and 
follow-up visits. A PK evaluable subject is defined as one with a minimum of one PK 
sample from Days 3, 15, 29 and 60, with accurate dosing and sample time histories. The 
key PK parameter to be estimated is the drug’s clearance.
4.4.
Design Justification
Study TAF113577 is an open-label single-arm study and will not include a control arm. 
This pediatric PK bridging and safety study will test appropriate doses of TQ in pediatric 
subjects selected to achieve similar levels of exposure observed in adults treated with 
300mg TQ.  The dosing regimen in the pediatric population is based on allometric scaling 
and targeting a systemic exposure comparable to the 300 mg exposures in adults. Given 
the evidence suggests that the disease process in adults and children is similar, it is 
appropriate to draw conclusions from our emerging adult data set to inform our pediatric 
study design. This assumption allows the use of this pharmacokinetic bridging study to 
support the dose selection in infants, children and adolescents aged 6 months to <16 
years.  
The study will recruit a target of 60 subjects. Safety data will be collected for the entire 
study (up to 120 days, as the half-life of TQ is 2–3 weeks).  With regard to efficacy, the 
study is being conducted in areas with known high recurrence rates in adults.  Therefore, 
high efficacy in this study is not indicative of low background recurrence rates.
Pharmacokinetic samples will be collected in order to achieve the primary objective of 
the study. However, in order to minimize distress in this pediatric population, a sparse 
sampling scheme will be used to reduce the frequency and volume of blood collected and 
a population PK modelling and simulation approach will be utilized. Small volume 
venous sampling (≤1 mL whole blood) and/or microsampling (70 µL whole blood) will

be employed to minimize volume of blood taken from subjects.  Furthermore, up to two 
interim analyses have been included in this study, so that full PK sampling can be 
stopped as soon as sufficient data have been collected.  As mentioned in Section 4.1, once 
full PK sampling is stopped, two samples will be collected from each remaining enrolled 
subject at Day 15 and Day 29 to provide data for the final population PK analysis of TQ 
to be conducted at the end of the study.  Simulations were used to identify appropriate 
sampling times and total study sample size (See Appendix 9, Section 12.9, Tafenoquine 
Pediatric Population-PK Trial Simulation). The primary objective of this PK bridging 
study is to adequately characterize the systemic TQ exposure in the pediatric population. 
Consequently, a sparse PK sampling scheme is selected to reliably estimate TQ clearance 
(CL) and thereby characterize exposure, i.e., AUC [AUC (0-∞) = dose/CL]. Other 
information that cannot be obtained from the pediatric data owing to the sparse sampling 
design, e.g. absorption rate, will be obtained from the adult exposure data and population 
PK model.
In the phase 2 adult TQ program, efficacy was measured at 4 months and 6 months
[GlaxoSmithKline Document Number 2013N160035_00]. The majority of the 
recurrences across all treatment groups were observed prior to 4 months and efficacy of 
TQ 300 dose at 4 months was significantly higher than placebo (Figure 3). To allow for a 
shorter follow up period in the pediatric study population, recurrence-free efficacy will be 
measured at four months rather than at four and six months as measured in the adult 
studies.

Dose Justification in Cohort Aged <2 years
There is no lower age limit below which infants and children are not susceptible to vivax 
malaria. There is, however, a balance to be struck in terms of collecting data sufficient to 
define an appropriate dose for infants, versus limiting the number of study related 
assessments to which this highly vulnerable group are subjected. Where possible, PK data 
from an additional cohort of six infants aged ≥6 months to <2 years (weighing ≥5 kg) will 
be obtained to define dosing in infants down to 6 months. Available data from this cohort 
will be combined with data obtained from the main cohort as part of the final population 
PK analysis.  The lower age of 6 months is based on the age at which G6PD enzyme 
activity reaches maturity.  The pediatric population PK model used for dose prediction 
has been developed based on adult patient data and includes an allometric function for 
weight-based dosing. Allometric scaling accounts for size differences only and not age-
related changes in metabolizing enzymes or renal function. However, the generalized 
functional immaturity in metabolizing enzyme activity and renal function approach adult 
levels about 6 months after birth [Kearns, 2003].  Thus, the model is appropriate for dose 
prediction in this cohort.
The decision to enrol subjects aged ≥6 months - <2 years will be based on a review of 
exposure data as well as of safety results from the first interim analysis.  Particular 
attention will be paid to the reporting of adverse events related to decreases in 
hemoglobin (Hb), methemoglobin (metHb) levels, increases in creatinine, and any reports 
of phototoxicity.
4.5.
Dose Justification
As mentioned above, subjects will be dosed based on weight (see Section 6.1).  The 
pediatric dose rationale is based on achieving a target median TQ exposure AUC(0-∞) of  
96 µg.h/mL. The term AUC listed throughout this document refers to the AUC(0-∞) 
unless specified otherwise and is estimated based on model predicted post hoc CL 
estimates [AUC (0-∞) = dose/CL].
The currently proposed doses for the pediatric study are derived from a population PK 
model built using the systemic TQ exposure data from adults in part 1 of Study 
TAF112582. The population PK model incorporated allometric scaling for bodyweight. 
Based on this population PK model, a 60 kg adult on 300mg dose will have a median 
AUC(0-∞) of 96 μg.h/mL (95% prediction interval 55-162 μg.h/mL). The proposed 
starting doses for this pediatric study are predicted to achieve a similar target exposure 
after accounting for the subjects’ bodyweight. 
The lower prediction limit of AUC(0-∞) of 55 μg.h/mL from the population PK model is 
consistent with the cut-off obtained from the CART analysis (AUC(0-∞) of 56.4 
μg.h/mL). The CART analysis conducted with exposure – efficacy/response data from 
part 1 in Study TAF112582 identified a clinically relevant TQ AUC of 56.4 ug.hr/mL. 
Subjects with TQ AUC ≥ 56.4 ug.hr/mL  were likely to have significantly lower relapses 
compared to subjects with < 56.4 ug.hr/mL TQ AUC. This population PK model based 
dose rationale therefore provides a high degree of confidence in the efficacy in the 
pediatric population using such PK bridging approach.

Investigational Product (IP) – SB-252263
Hemolysis in G6PD-deficient subjects
(PRIMARY RISK)
Tafenoquine is an 8-aminoquinoline, a class of 
drug known to exert oxidative effects on Hb. In 
patients with G6PD deficiency (or other 
disorders of erythrocytic pentose phosphate 
pathway of glucose metabolism) hemolysis is 
expected due to RBCs lack of capacity to 
protect itself against oxidative effects of such 
drugs.  Hemolysis has been reported in G6PD 
deficient patients inadvertently recruited into 
previous TQ studies.

All subjects with <70% G6PD activity will 
be excluded. Subjects with Hb levels <8
g/dL will also be excluded.

Protocol-defined SAE criteria will be 
adopted; defined as, ≥ 3.0 g/dL or 30% 
decline in Hb from the baseline value, or a 
Hb value <6 g/dL, to aid in safety 
monitoring.  

Recommendations for clinical management 
of hemolysis will be provided as part of
investigator training.
Methemoglobinemia (metHb)
Methemoglobinemia has been observed in 
previous studies associated with larger total 
doses of TQ than are being considered for 
clinical investigation.  Risk factors have been 
assessed and include a strong relationship 
between MetHb development, TQ dose, and 
body surface area.
The doses recommended for this study, 
designed to achieve similar levels of exposure 
observed in adults treated with 300mg TQ, 
should pose minimal risk of causing elevations 
of metHb of clinical concern.

Methemoglobin percentage will be 
monitored non-invasively at selected times 
throughout the study.
High Systemic Exposure to TQ
In a cohort of patients taking 600 mg TQ (first 
part of Study TAF112582) the highest AUC(0-∞) 
observed was 275 μg.h/mL.

The presence of an observed AUC(0-∞) in 
any subject of >275 μg.h/mL will trigger a 
review of dosing in the study.
Liver Transaminase Elevations
Preclinical repeat dose toxicology studies 
observed liver changes that were fully or 
partially reversible.
During the TQ thorough QT study (TAF114582) 

Conduct liver function tests – baseline and 
Day 8.

TQ dose limited to 300mg total dose 
equivalent in pediatric subjects.

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
two adult subjects receiving 1200 mg TQ 
experienced transient elevations in liver 
transaminases. It was concluded that high 
doses of TQ appeared to be associated with 
transient increases in transaminases. However, 
based on data from TAF112582 Part 1 there is 
no safety signal for hepatoxicity for doses of 
600mg and 300mg.  
Keratopathy
No ophthalmological changes were observed in 
preclincial species. 
Reversible vortex keratopathy was observed in 
clinical trials at higher doses and/or longer 
duration of treatment than are being studied 
here. 
Keratopathy was not observed in a limited 
number of adult patients (n=15) who underwent 
ophthalmological exams at 300mg dose in 
TAF112582 Part 1 study.

This risk will be mitigated in other studies 
within the tafenoquine program

Appropriate training will be provided at 
investigator meetings on these potential 
ophthalmological changes
Retinal Toxicity
No ophthalmological changes have been 
observed in preclinical species. Previous clinical 
studies (057, 058 and TAF 106491) have 
included substantive ophthalmic assessments. 
No evidence of retinal toxicity associated with 
TQ was observed in any of the TQ-treated 
subjects in these studies as per conclusion of 
Ophthalmic Advisory board Nov ’09. 
Irreversible retinopathy has been reported with a 
potential combination partner - CQ (and 
hydroxychloroquine). Effects with CQ are dose 
related and have been observed following 
cumulative total doses of >1g base/kg body 
weight. CQ dose used in treatment of P. vivax is 
a total of 25mg/kg over 3 days. Retinopathy 
associated with severe falciparum malaria is 
reported in the literature but rare in vivax.

This risk will be mitigated in other studies 
within the tafenoquine program

Appropriate training will be provided at 
investigator meetings on these potential

Potential Risk of Clinical Significance
Summary of Data/Rationale for Risk
Mitigation Strategy
Renal Function
Transient increases in serum creatinine have 
been observed in clinical studies in adults. A 
renal safety study was conducted and 
concluded that TQ, when given as 200 mg x 3 
days loading dose followed by weekly 200 mg 
dosing for 6 months was non-inferior to placebo 
when comparing mean change from baseline 
glomerular filtration rate.
In TAF112582 study part 1 outliers were 
characterized by isolated transient rises in 
creatinine with rapid recovery and no consistent 
time to onset at a particular dose for the outliers.
A preclinical assessment of inhibition of renal 
transporters has demonstrated that TQ inhibits 
organic cation transporter 2 (OCT2), multidrug 
and toxin extrusion 1 transporter (MATE1) and 
multidrug and toxin extrusion 2K transporter 
(MATE-2K). The changes in serum creatinine 
are thought to be related to this tubular 
transporter interaction.

Conduct renal function testing in the 
proposed pediatric study – baseline and 
Day 8. 

Include drugs that are excreted via these 
transporters in the list of prohibited 
medications.
Nervous system & psychiatric disorders
Phase 3 results in adult patients showed mild to 
moderate self-limiting nervous system & 
psychiatric disorders including dizziness, anxiety 
& insomnia.

Consider excluding patients with a history 
of serious psychiatric disorders such as 
psychosis, depression and suicidal 
ideation.
Use in Pregnancy and Lactation
Preclinical data reported no adverse effects on 
fertility, embryofetal development or on post-
natal survival.
No clinical studies have been conducted in 
humans during pregnancy.  There may be 
concern about risk to a fetus who is G6PDd and 
risk to breastfed infants whose G6PD status 
may be unknown.

Pregnant or lactating women are excluded 
from the study.
Phototoxicity
Pre-clinical studies concluded that there was a 
possibility that TQ was phototoxic.  However,

Benefit Assessment
In the absence of radical cure treatment, a percentage of patients with P. vivax malaria 
will relapse due to the liver being infected with hypnozoites (the dormant form of the 
parasite).  P. vivax malaria is most prevalent primarily in Asia, Asia-Pacific and Latin 
American countries and frequency of relapse rates may impact product use.  Relapse rates 
vary with strain and are difficult to measure due to confounding by re-infection. The 
WHO has generalized relapse rates in the following countries as: India (15-20%), 
Indonesia (30%) and South East Asia (50-60%).  P. vivax can cause a debilitating fever 
and, as it preferentially invades reticulocytes as well as causing bystander hemolysis, can 
also lead to the development of anemia. Repeated relapses are similarly debilitating and 
may result in further episodes of fever, weight loss, malnutrition and high output heart 
failure, especially in children. Consequences are loss of work or school days (e.g., 5.4 
days school absenteeism per episode) and hospitalization (especially children) due to 
vomiting, dehydration and asymptomatic anemia (resulting in transfusion). 
Due to its long half life, TQ can be administered as a single oral dose and is therefore a 
more convenient treatment regimen with the potential to improve patient compliance. 
Improved compliance could also lead to improved clinical outcomes for patients with 
P. vivax malaria by further reducing recurrence rates.
4.6.3.
Overall Benefit:Risk Conclusion
Tafenoquine is being developed with the aim of a benefit:risk profile which is at least as 
good as the current gold standard therapy PQ. Our intent is to evaluate whether improved 
compliance could also lead to improved clinical outcomes for patients. Tafenoquine 
should have no clinically significant side effects that will restrict its use as a first line 
agent in treatment of P. vivax malaria when used in combination with a G6PD test and 
recommended therapies to treat the blood stages of infection.  With specific regard to this 
study, the overall benefit:risk is favorable to all subjects, given that all are receiving 
active treatment.

A subject may withdraw or be prematurely withdrawn for any of the reasons presented in 
the list above. If a subject withdraws consent the site should offer to conduct safety 
assessments through Day 120.
Subjects and/or their parent/legal guardian are not obligated to state the reason for 
withdrawal from this study.  However, the reasons for withdrawal, or failure to provide a 
reason, must be documented by the investigator on the Completion/Withdrawal section of 
the electronic Case Record Form (eCRF).  If a subject is withdrawn from the study for 
any reason, the investigator must make every effort to perform the study evaluations as 
specified for the Withdrawal visit as applicable.
The following actions must be taken in relation to a subject who fails to attend the clinic 
for a required study visit:

The site must attempt to contact the parent/legal guardian of the subject and re-
schedule the missed visit as soon as possible. 

The site must counsel the subject and/or parent/legal guardian on the importance of 
maintaining the assigned visit schedule and ascertain whether or not the subject 
wishes to and/or should continue in the study. 

In cases where the subject is deemed ‘lost to follow up’, the investigator or designee 
must make every effort to regain contact with the subject and parent/legal guardian
(where possible, three telephone calls and if necessary a certified letter to the 
subject’s last known mailing address or local equivalent methods). These contact 
attempts should be documented in the subject’s medical record. 

Should the subject continue to be unreachable, only then will he/she be considered to 
have withdrawn from the study with a primary reason of “Lost to Follow-up”. 
5.4.1.
Liver Chemistry Increased Monitoring Criteria
Liver chemistry stopping and increased monitoring criteria have been designed to 
assure subject safety and evaluate liver event etiology (in alignment with the FDA 
premarketing clinical liver safety guidance): 
http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guid
ances/UCM174090.pdf
Figure 4 below presents the algorithm for evaluating and monitoring liver chemistry data.  
It should be noted that, given TQ is administered as a single dose, there will be no 
opportunity to discontinue study treatment.  However, liver event follow-up assessments 
would still apply if liver increased monitoring criteria are met.

5.4.2.
QTc Stopping Criteria
QTc stopping criteria will not be employed in this study.
A TQ definitive QTc study, Study TAF114582 [GlaxoSmithKline Document Number 
2012N145359_00], demonstrated a lack of effect on QTcF elongation at adult clinical 
doses (300 and 600mg). CQ does have a propensity to cause QTc prolongation; however, 
in TQ drug-drug interaction (DDI) Study TAF106491 [GlaxoSmithKline Document 
Number WD2009/01503/00] no difference was seen in PK and QTcF changes between 
CQ/TQ groups with all groups showing the same pattern of elongation as with CQ alone, 
for both frequency and magnitude of changes.
The DDI study concluded that there was no trend over time for increased QTc intervals in 
those treated with TQ alone.  Therefore, no ECG monitoring is planned for this study.

STUDY TREATMENT
Chloroquine will be provided to subjects outside the parameters of this study, and 
according to local/national treatment guidelines.  Potential subjects who are slide-positive 
for P. vivax will begin CQ treatment and sites will have 48 hours to obtain full subject 
consent and assent, as applicable.  Consented subjects will be screened, randomized and 
dosed with TQ on Day 1.  Two formulations of TQ will be made available; a 150 mg 
film-coated tablet (TQ adult tablet), and a 50mg fast-dispersing film coated tablet (TQ 
pediatric tablet; Table 1).  Instructions for preparation and administration of the TQ 
formulations will be provided in the SRM.

This is an open-label, single arm study, and all subjects will receive CQ and TQ.  
Subjects will be dosed based on weight, with the goal to achieve a median TQ exposure 
of 96 µg.h/mL, the median exposure observed in adults following administration of a 300 
mg dose of TQ.  The TQ doses presented in Table 2 below were selected using a 
population PK model based on adult data and incorporation of allometric scaling.

The single dose of TQ will be administered at the investigator site.  Subjects >35 kg have 
the choice of taking the TQ adult tablet or the TQ pediatric tablet.  All study medication 
should be administered with food. If the subject vomits within 1 hour following dosing, a 
repeat dose should be given. If a subject sequentially vomits two doses of study 
medication he/she will be considered intolerant to study medication. These subjects will 
be withdrawn from study medication and be given appropriate rescue medication as 
outlined in Section 6.9.1.2.
6.2.
Planned Dose Adjustments
The TQ doses and weight banding may be refined after a planned interim analysis of at 
least 16 subjects and based on safety and predicted exposures for the pediatric population. 
The observed pediatric exposure data will be compared with corresponding adult 
exposures that have been shown to be efficacious in order to help inform the need for any 
dose adjustments.

Preparation/Handling/Storage/Accountability
No special preparation of study treatment is required.

Only subjects enrolled in the study may receive study treatment and only authorized 
site staff may supply or administer study treatment.  All study treatments must be 
stored in a secure environmentally controlled and monitored (manual or automated) 
area in accordance with the labelled storage conditions with access limited to the 
investigator and authorized site staff. 

The investigator, institution, or the head of the medical institution (where applicable) 
is responsible for study treatment accountability, reconciliation, and record 
maintenance (i.e. receipt, reconciliation and final disposition records).  

Further guidance and information for final disposition of unused study treatment are 
provided in the Study Reference Manual (SRM).

Under normal conditions of handling and administration, study treatment is not 
expected to pose significant safety risks to site staff.

A Material Safety Data Sheet (MSDS) or equivalent document describing 
occupational hazards and recommended handling precautions either will be provided 
to the investigator, where this is required by local laws, or is available upon request 
from GSK.
Precautions will be taken to avoid direct contact with the study treatment.  A Material 
Safety Data Sheet (MSDS) describing occupational hazards and recommended handling 
precautions will be provided to the investigator. In the case of unintentional occupational 
exposure notify the monitor, Medical Monitor and/or GSK study contact.
6.6.
Compliance with Study Treatment Administration
Compliance with TQ will be assessed in all subjects by directly observing the taking of 
medication while at the investigator center.  Despite being administered outside of this 
study, CQ compliance should be monitored by the site and recorded in the subject’s 
source documentation.
6.7.
Treatment of Study Treatment Overdose
An overdose for this study will be considered as any dose of study medication that is 
more than the planned dose on each dosing occasion.  
Tafenoquine
No specific antidote for tafenoquine has been identified.  In the event that overdose or 
toxicity does occur, individuals should be managed with appropriate supportive measures

and clinical judgement.  Immediate induction of emesis and/or gastric lavage is not 
recommended. Hemodialysis is unlikely to be clinically useful as tafenoquine is highly 
protein-bound.
Methemoglobinemia has been observed in clinical trials at therapeutic doses of 
tafenoquine; clinically significant levels could possibly be encountered in overdose.  
Signs and symptoms of methemoglobinemia include (but are not limited to) blue 
discoloration of the skin and lips, and shortness of breath.
Chloroquine 
No specific antidote for chloroquine has been identified.  In the event that overdose or 
toxicity occurs, individuals should be managed with appropriate supportive measures and 
clinical judgement. Immediate induction of emesis and/or gastric lavage is not 
recommended.
Drowsiness, blurred vision, diplopia, blindness, tinnitus, convulsions and coma can occur 
with overdose. Chloroquine is a known cardiovascular toxin thus cardiac monitoring and 
resuscitation facilities are essential. Thus in addition to dizziness, nausea, vomiting, 
diarrhea and headache hypotension, cardiogenic shock and cardiac arrest may occur. The 
12 lead ECG may demonstrate decreased T waves, widening of the QRS complex, which 
may lead to ventricular tachycardia and/or fibrillation.
In the event of an overdose the investigator should:
1.
contact the Medical Monitor immediately
2.
closely monitor the subject for adverse events (AEs)/serious adverse events (SAEs) 
and laboratory abnormalities until TQ and/or CQ can no longer be detected 
systemically (at least 90 days for TQ and 28 days for CQ)
3.
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 subject.
6.8.
Treatment after the End of the Study
There is no extension study planned and thus no post study treatment will be offered 
except for subjects diagnosed with malaria at the end of the study who will receive rescue 
medication outlined in Section 6.9.1.2.
The investigator is responsible for ensuring that consideration has been given to the post-
study care of the subject’s medical condition, whether or not GSK is providing specific 
post-study treatment.

Permitted Medications and Non-Drug Therapies
6.9.1.1.
Concomitant Medications
All subjects can be given paracetamol during the study but administration time must be 
recorded in the eCRF. Allowable antibiotics are penicillins, cephalosporins, carbapenems 
and aminoglycosides.
All concomitant medications (prescription and non-prescription) taken during the study 
should be recorded in the eCRF. The minimum requirement is drug name and date of 
administration.
6.9.1.2.
Rescue Medication
Subjects requiring rescue medication will be given appropriate medication in accordance 
with site (local) or national treatment guidelines for P. vivax malaria or; e.g., 
P. falciparum malaria, whichever is applicable.  Subjects offered rescue medication 
should be followed up for safety assessment through the Day 120 visit to ensure
resolution of the malaria infection.  Details of rescue medication including reason for the 
rescue medication offered (e.g., withdrawal from study, treatment failure) should be 
recorded in the eCRF.
6.9.2.
Prohibited Medications and Non-Drug Therapies
The following drugs are prohibited for use from 30 days prior to entry in the study 
through Day 120:

Anti-malarials and other medicines with known anti-malarial activity (with the 
exception of CQ being given to potential subjects prior to randomization).
Results from an in vitro renal transporters study showed that TQ inhibits the renal 
transporters MATE1, MATE2-K AND OCT2.  Inhibition of these transporters may 
explain mild, transient, asymptomatic increases of creatinine observed in previous 
clinical studies and may lead to increased exposure to medications excreted via these 
transporters.  The following drugs are prohibited for a period of 21 days immediately 
following the blinded dose of TQ.

Anti-diabetic drugs of the biguanide class:
o
Phenformin
o
Buformin

Anti-arrhythmic drugs:
o
Dofetilide
o
Procainamide
o
Pilsicainide

Metformin, another biguanide anti-diabetic, may continue to be taken provided the 
subject has serum creatinine below the upper limit of normal and has no concomitant 
medical condition that increases the risk of lactic acidosis.
The use of herbal remedies during the course of the study is to be avoided. However, if 
taken this should be recorded in the eCRF under concomitant medication.

Screening and Critical Baseline Assessments
Study site personnel must obtain written, dated informed consent from the parent(s) or 
legal guardian(s) of the subject, as well as assent from the subject, if applicable, prior to 
the initiation of any screening procedures. 
The following clinical and laboratory assessments will be conducted at screening (prior to 
the dose of TQ) as detailed in the Time and Events (Section 7.1):

Demographic data will be collected to include details of date of birth, gender, race 
and ethnicity

Medical history will be collected, including medical, disease and therapy 
histories; and, cardiovascular history and associated risk factors

A brief physical examination will be conducted including:
o
Cardiovascular examination
o
Abdominal examination including assessment of splenomegaly
o
Respiratory examination

Vital signs will be assessed. These include height, weight, temperature (oral, 
axillary or tympanic), heart rate, respiratory rate, systolic and diastolic blood 
pressure

Investigators will assess P. vivax malaria symptoms at baseline.  The incidence 
and severity (defined as absent, mild, moderate, severe, or unknown) of the 
following symptoms will be recorded: chills and rigors, headache, dizziness, 
abdominal pain, anorexia, nausea, vomiting, diarrhea, pruritis or itching, and 
coughing.  The date of onset of symptoms will also be recorded.  The investigator 
or designee can also assess and record any other P. vivax malaria symptoms.

Blood smears for parasitological assessment will be collected and examined for 
the presence of Plasmodium species asexual parasites and gametocytes (see 
Section 7.4 and the SRM for further details).  Given the subject may have already 
received one or more doses of CQ, the parasitological assessment at Day 1 may 
be negative.

A blood sample will be collected on filter paper and stored for future plasmodium 
genotyping analysis.

Current and prior medications will be reviewed including any anti-malarial 
medication that has been used.

G6PD status will be assessed using quantitative spectrophotometric analysis 
(further instructions can be found in the SRM). The quantitative analysis will be 
used to determine the subject's eligibility for the study. One or more G6PD rapid 
point of care tests may also be performed at baseline.

o
Periodic external quality assurance testing will be performed to ensure 
high quality G6PD assay data.  Procedures for quality assurance will be 
described in detail in the SRM.

The following laboratory assessments will be performed by local laboratories at 
screening and prior to dosing TQ:
o
Hematology analysis will include: Hb, hematocrit (Hct), red blood cells 
(RBC), white blood cells (WBC), mean cell volume (MCV), differentiated 
WBC, platelets and reticulocytes (for conversion to absolute).
o
Clinical chemistry evaluations will include: blood urea nitrogen (BUN), 
serum creatinine, total and indirect bilirubin and liver chemistries (alanine 
aminotransferase (ALT), aspartate aminotransferase (AST), alkaline 
phosphatase (ALP) and creatine phosphokinase (CPK)).

A urine pregnancy test will be performed on females of childbearing potential that 
is routinely used at the site, provided the test has sensitivity for human chorionic 
gonadotropin (hCG) of ≤ 25 mIU/mL.

Methemoglobin levels will be assessed using a non-invasive signal extraction CO-
Oximeter handheld machine.

Center
 (Manuas, Brazil) only will perform the following ophthalmic 
assessments prior to randomization:
o
Visual acuity will be assessed by standard methods
o
Slit lamp examination of the cornea to evaluate for vortex keratopathy 
o
Retinal digital imaging (color photographs, fundus autofluorescence and 
OCT)
7.3.
Unscheduled Visits
Subjects who have one or more visits outside the allowable time window defined for each 
scheduled visit will undergo all the procedures and assessments described in the Time 
and Events Table (Section 7.1) with the exception of assessments performed only at 
screening and the PK assessments. Subjects should be able and/or encouraged to return to 
the clinic for unscheduled visits at anytime during the 120-day study period. In addition, 
subjects must return to the clinic anytime they are experiencing a recurrence of malaria 
symptoms.
7.4.
Efficacy
The study is not powered to produce precise estimates of efficacy. However, the 
estimates of recurrence-free efficacy at Day 120 will be reviewed at each interim and at 
the final analysis of the study. The doses in the pediatric study (Section 6.1) have been 
selected to match the exposure following an efficacious dose of TQ (300 mg) in adults,

and are therefore expected to provide similar levels of efficacy in the pediatric 
population.
Parasitology
Microscope blood slides will be prepared pre-dose at screening on Day 1 to confirm the 
presence (positive or negative) of P. vivax malaria (asexual parasites and gametocytes), 
and on Day 8 to confirm the parasite has cleared.  Blood films will also be prepared 
during follow-up on Days 29, 60, 90 and 120.  In addition, blood films should be 
obtained at the recurrence visit or withdrawal visit as applicable. At each time point two 
thick and one thin film slides should be prepared on separate slides and one additional 
unstained slide with both thick and thin films retained for quality control.  For detailed 
instructions on the methodology for staining please refer to the SRM.
Parasite Genotyping
Two drops of peripheral blood will be collected onto pre-printed filter paper for 
subsequent DNA extraction and genetic analysis of Plasmodium species on all subjects 
on Day 1, prior to TQ dose and; if necessary, at the time of the first recurrence.
Analysis of the P. vivax genes, such as PvMSP-1, PvCSP and PvAMA-1, as well as any 
other markers deemed appropriate, will be used to distinguish between genetically 
homologous and genetically heterologous infection.
External quality control
External quality control of slide readings will be conducted by an independent laboratory. 
They will examine a proportion of slides from each study site. The procedure for quality 
control will be described in the SRM.
7.5.
Safety
Planned time points for all safety assessments are listed in the Time and Events Table 
(Section 7.1).  Additional details on specific assessments are provided below.  Safety 
information will be reviewed on a monthly basis by a GSK/MMV safety review team.
7.5.1.
Adverse Events (AE) and Serious Adverse Events (SAEs)
The definitions of an AE or SAE can be found in Appendix 3 (Section 12.3.1 and Section
12.3.2).  The investigator and their designees are responsible for detecting, documenting 
and reporting events that meet the definition of an AE or SAE.
7.5.1.1.
Protocol-Defined SAE
Hemoglobin decreases of ≥30% of >3 g/dL from baseline; or, an overall drop in Hb 
below 6.0 g/dL in the first 15 days of the study should be reported as an SAE.


2014N207627_03
CONFIDENTIAL
TAF113577
49
7.5.1.2.
Time period and Frequency for collecting AE and SAE information

AEs will be collected from the start of Study Treatment and SAEs will be collected 
from the time of consent.  AEs and SAEs will continue to be collected until the 
follow-up contact (see Section 7.5.1.4), at the timepoints specified in the Time and 
Events Table (Section 7.1).

Medical occurrences that begin prior to the start of study treatment but after 
obtaining informed consent may be recorded on the Medical History/Current 
Medical Conditions section of the CRF.

Any SAEs assessed as related to study participation (e.g., protocol-mandated 
procedures, invasive tests, or change in existing therapy) or related to a GSK product 
will be recorded from the time a subject consents to participate in the study up to and 
including any follow-up contact. 

All SAEs will be recorded and reported to GSK within 24 hours, as indicated in 
Appendix 3 (Section 12.3.4 and Section 12.3.6).

Investigators are not obligated to actively seek AEs or SAEs in former study 
subjects. However, if the investigator learns of any SAE, including a death, at any 
time after a subject has been discharged from the study, and he/she considers the 
event reasonably related to the study treatment or study participation, the investigator 
must promptly notify GSK.
NOTE: The method of recording, evaluating and assessing causality of AEs and SAEs 
plus procedures for completing and transmitting SAE reports to GSK are provided in 
Appendix 3 (Section 12.3).
7.5.1.3.
Method of Detecting AEs and SAEs
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended 
and non-leading verbal questioning of the subject and/or the parent/legal guardian is the 
preferred method to inquire about AE occurrence.  Appropriate questions include:

“How does your child seem to feel?”

“Has your child had any (other) medical problems or seem to act differently in any 
way since his/her last visit/contact?”

“Has your child needed to take any medicines, other than those provided in this 
study, since his/her last visit/contact?”
7.5.1.4.
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
subject at subsequent visits/contacts.  All SAEs, and non-serious AEs of special interest 
will be followed until resolution, until the condition stabilizes, until the event is otherwise 
explained, or until the subject is lost to follow-up (as defined in Section 5.4). Further 
information on follow-up procedures is given in Appendix 3 (Section 12.3.5).

TAF113577
50
7.5.1.5.
Cardiovascular and Death Events
For any cardiovascular events detailed in Appendix 3 (Section 12.3.3) and all deaths, 
whether or not they are considered SAEs, specific Cardiovascular (CV) and Death 
sections of the CRF will be required to be completed.  These sections include questions 
regarding cardiovascular (including sudden cardiac death) and non-cardiovascular death. 
The CV CRFs are presented as queries in response to reporting of certain CV MedDRA 
terms.  The CV information should be recorded in the specific cardiovascular section of 
the CRF within one week of receipt of a CV Event data query prompting its completion.  
The Death CRF is provided immediately after the occurrence or outcome of death is 
reported. Initial and follow-up reports regarding death must be completed within one 
week of when the death is reported.
7.5.1.6.
Disease-Related Events and/or Disease-Related Outcomes Not 
Qualifying as SAEs
Occurrence of malaria is an efficacy endpoint for this study. Consequently malaria should 
not typically be reported as an AE/SAE and will not be subject to the standard process for 
expedited reporting of SAEs to GSK (even though the event may meet the definition of a 
serious adverse event).  The occurrence of malaria and any associated signs and 
symptoms must instead be recorded on the Malaria Signs and Symptoms (i.e., Disease-
Related Event [DRE]) page in the subject’s eCRF.  
The following are considered to be the common signs and symptoms associated with 
malaria infection/recurrence which should not be reported as AEs/SAEs but captured on 
the DRE page. However, this should be done ONLY IF confirmed with a positive slide 
reading for the presence of P. vivax malaria at the time symptoms are reported.  If any of 
the following symptoms are reported and the slide read is negative, they should be 
reported as an AE or SAE as usual.

Pyrexia

Chills

Rigor

Headache
These DREs will be monitored by the GSK Safety Review Team on a routine basis. 
However, if the following condition applies, then the event should be reported as an SAE 
using the standard process:
“The event is, in the Investigator’s opinion, of greater intensity, frequency, or duration 
than expected for the individual subject.”


2014N207627_03
CONFIDENTIAL
TAF113577
51
If the above condition is met then record the event on the SAE page rather than the DRE 
page and report promptly (i.e., expedited reporting, see Appendix 3, Section 12.3.6) to 
GSK.
As the occurrence of malaria is an efficacy endpoint for this study, should malaria be 
reported as an SAE, it will not be subject to expedited reporting regardless of the 
“expectedness” or “relatedness” of the event.
7.5.1.7.
Regulatory Reporting Requirements for SAEs
Prompt notification by the investigator to GSK of SAEs and non-serious AEs related to 
study treatment (even for non- interventional post-marketing studies) is essential so that 
legal obligations and ethical responsibilities towards the safety of subjects and the safety 
of a product under clinical investigation are met. 
GSK has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a product under clinical investigation.  GSK will 
comply with country specific regulatory requirements relating to safety reporting to the 
regulatory authority, Institutional Review Board (IRB)/Independent Ethics Committee 
(IEC) and investigators.
Investigator safety reports are prepared for suspected, unexpected serious adverse 
reactions according to local regulatory requirements and GSK policy and are forwarded 
to investigators as necessary.
An investigator who receives an investigator safety report describing a SAE(s) or other 
specific safety information (e.g., summary or listing of SAEs) from GSK will file it with 
the IB and will notify the IRB/IEC, if appropriate according to local requirements.
7.5.2.
Pregnancy
Information on the occurrence of new pregnancies will be collected over the period 
starting at screening (Day 1) and ending at the Day 120 follow-up assessment.  Only 
those pregnancies that occur following the first dose of study medication will be reported 
to GSK.  Follow-up information will be collected for pregnancies occurring throughout 
the study.
If a pregnancy is reported then the investigator should inform GSK within 2 weeks of 
learning of the pregnancy and should follow the procedures outlined in Appendix 4
(Section 12.4).
7.5.3.
Physical Exams
Physical examinations will be performed during the treatment period (Day 1), the follow-
up period on Days 3, 8, 29, 60, 90 and 120 and if there is a relapse or premature 
withdrawal visit.  (At center 
 physical examinations are required at all follow-up 
visits.)  When conducting the exam, please note:

A brief physical examination will include, at a minimum, assessments of the lungs, 
cardiovascular system, and abdomen (liver and spleen).

pharmacokinetic (PK) measurements, and if there is a recurrence or premature 
withdrawal visit.  (At center
 vital signs are to be performed at all follow-up 
visits.)  Vital signs include height and weight (screening only), blood pressure, 
temperature, heart rate and respiratory rate.
7.5.5.
Concomitant Medications
Information on concomitant medications will be collected at all scheduled treatment and 
follow-up visits, and if there is a recurrence or premature withdrawal visit.
7.5.6.
Clinical Safety Laboratory Assessments
Clinical chemistry and hematology samples will be analyzed by local laboratories.  All 
protocol required laboratory assessments must be conducted in accordance with the 
Laboratory Manual, and Protocol Time and Events Schedule (Section 7.1).
Hematology tests will be conducted on the Day 1, 3 and 8 visits.  Clinical chemistry tests 
will be conducted on the Day 1 and Day 8 visits.  In addition, laboratory tests may be 
conducted at any time during the study, as warranted by the condition of the subject and 
at the investigator’s discretion.  All laboratory results that are considered clinically 
significant should be recorded as AEs.  The panel of tests to be analyzed are detailed 
below in Table 3 and Table 4.  All laboratory data will be used for the purpose of safety 
analysis and reporting for this study.

Hemoglobin and/or Hct measurements that deviate substantially from previous readings 
should be immediately repeated via venous sampling.  If a significant drop in Hb or Hct 
is observed, all additional hematology and clinical chemistry labs should be obtained 
immediately.  In addition, a blood sample should be drawn for G6PD genotyping (see 
Section 7.7).
Methemoglobin status will be assessed at Day 1 and Day 8.  Subjects with anemia may 
have symptomatic methemoglobinemia (e.g., blue discoloration of skin and lips, 
shortness of breath) at levels lower than subjects with normal hemoglobin levels

(symptoms typically do NOT occur with MetHb values <20% in subjects with normal 
hemoglobin levels).
All laboratory tests with values that are considered clinically significantly abnormal 
during participation in the study should be repeated until the values return to normal or 
baseline.  If such values do not return to normal within a period judged reasonable by the 
investigator, the etiology should be identified and the sponsor notified.
7.5.7.
Ophthalmic Assessments (Center 
Only)
Ophthalmic assessments will be performed at Center 
(Manaus, Brazil) at 
screening and prior to randomization, at Day 120 and at the withdrawal visit, if 
applicable. The Principal Investigator and site ophthalmologist will determine if the child 
is able to comply with the assessments, based on their malaria status and ability to 
reasonably cooperate with the assessments.  Subjects who do not complete the
ophthalmic examination at baseline, including interpretable retinal imaging, should not 
complete ophthalmic exams at follow-up or withdrawal.  If a subject completes a portion 
of the ophthalmic exams at baseline, only those same exams should be completed at 
follow-up.
7.6.
Pharmacokinetics
Blood samples for PK analysis of TQ will be collected at the time points indicated in the 
Time and Events Table (Section 7.1).  The Day 3 sample should be taken 24-96 hours 
after TQ dosing and a concurrent set of vital signs should also be obtained.  Sample(s) of 
1 mL blood will be collected (via venipuncture) into blood tubes and/or 70 µL blood (via 
finger or heel prick) will be collected into capillary tubes. Each sample will be 
centrifuged to produce plasma and the plasma transferred into a tube for shipping to a 
central laboratory for analysis.  The actual date and time of each blood sample collection 
will be recorded. The timing and collection of PK samples may be altered and/or PK
samples may be obtained at additional time points to ensure sufficient PK monitoring. In 
addition, concentrations of CQ will be determined.  Details of the PK blood sample 
collection (both venipuncture and microsampling), processing, storage and shipping 
procedures are provided in the SRM.
Evaluation of correlation between venous and microsampling data will be made at each 
interim analysis. If microsampling data is deemed adequately representative of venous 
blood samples, any further PK sampling will switch predominantly to microsampling. 
However, up to two out of the four planned PK samples per subject may still be collected 
by both venous and microsampling methods. This will be as a back-up  given the primary 
objective of this study is to adequately characterize the PK of TQ in the pediatric 
population. The PK data hence is of critical value. In the event that microsampling data is 
deemed an inadequate representation of venous samples, any further PK sampling will be 
only by venous sampling. 
The sampling strategy of four PK samples per subject is designed to be sparse but 
adequately characterize the PK of TQ in the pediatric population. These four samples per 
subject will be reduced to two samples per subject at the earliest interim analysis once 
reliable characterization of TQ PK has been achieved.

STATISTICAL CONSIDERATIONS AND DATA 
ANALYSES
9.1.
Hypotheses
There are no hypotheses tested in this study.  The study is designed to characterize the 
TQ exposures in pediatric subjects.
9.2.
Sample Size Considerations
A minimum of 16 subjects are required to assess the clearance and hence exposures of 
TQ in pediatric subjects. However, a total of 60 subjects based on feasibility is required 
to assess overall safety in the pediatric population.
9.2.1.
Sample Size Assumptions
A population PK modelling and simulations-based approach was utilized to support 
appropriate study sample size and PK sampling times for the proposed population PK 
bridging study.  Based on these simulations, a sample size of 16 subjects and a sparse 
sampling scheme of four time points per subject (Day 3 (24 to 96 hours post TQ dose), 
Day 15, Day 29, and Day 60) are considered sufficient for the evaluation of the primary 
PK objective of estimating exposure within each weight band in pediatric subjects aged 
≥2 years to <16 years.
Assuming that the rates of absorption and distribution in this population will be similar to 
the adult population, this sparse sampling scheme allows for adequate estimation of TQ 
clearance (coefficient of variation < 40% within each weight band as per regulatory 
recommendation) and thereby exposure within each weight band while obtaining a 
minimum number of samples for each subject (Appendix 9, Section 12.9).


2014N207627_03
CONFIDENTIAL
TAF113577
56
9.2.2.
Sample Size Sensitivity
Population PK simulations were performed to assess the adequacy of study sample sizes 
of 4, 8, 16, 32, 64 subjects and different sampling schemes to determine exposure with 
sufficient precision. With sparse sampling of 3-4 time points per subject, a minimum of 
n=16 subjects are deemed adequate. However, if the variability is higher than expected at 
the interim analysis, the PK sampling may be continued with a larger sample size to 
provide exposure assessments across weight bands with sufficient precision (Appendix 9, 
Section 12.9).
9.2.3.
Sample Size Re-estimation or Adjustment
No sample size re-estimation will be performed.
9.3.
Data Analysis Considerations
9.3.1.
Key Analysis Populations
Safety Population: 
This population includes all subjects who received at least one dose of study medication. 
Primary PK Population:
This population will include all subjects with at least one PK sample taken at Days 3, 15, 
29 and 60.  The primary PK analysis to evaluate TQ exposure will be carried out using 
this population.
9.3.2.
Interim Analysis
Up to two interim analyses have been planned so that serial but sparse (i.e., 4 PK 
timepoints) PK sampling may be stopped at the earliest opportunity.  The first interim 
analysis will take place after a total of at least 16 subjects in the main cohort have PK 
evaluable data or 12 months post study initiation, whichever comes first. The second 
interim analysis will take place after a total of at least 32 subjects in the main cohort have 
evaluable PK data or at 24 months post study initiation, whichever comes first. The 
second interim analysis will take place only if serial but sparse PK sampling is continued 
after the first interim analysis.
At every interim analysis, the 95% prediction interval of AUCs based on the simulation 
with the population pharmacokinetic model will be generated for the mid-point of each 
weight band (at a population level). The population PK model predicted individual 
clearance estimates will be utilized to calculate exposure [AUC(0-∞) = Dose/CL]. If this 
interval lies within the 55-162 µg.hr/mL for the mid-point of each weight band, serial 
(but sparse) sampling can be stopped for any subjects enrolled further. These bounds 
were chosen because 95% of adult subjects dosed with the efficacious dose of 300 mg 
TQ in part 1 of Study TAF112582 had an AUC that fell within this range and the lower 
bound is consistent with the clinically relevant breakpoint of 56.4 μg.h/mL for the adult

CONFIDENTIAL
TAF113577
57
Phase IIb data (TAF112582 Part1). Recruitment will continue for safety data 
accumulation with these subjects having a PK assessment at two timepoints.
If it is found that due to insufficient number of children being enrolled in the lowest 
weight band(s) the prediction intervals are wider in that lowest weight band, then further 
serial (but sparse) sampling may be limited to the children being enrolled in the lowest 
weight band. The analyses will then be repeated after next set of 4 subjects and so on 
until the 95% prediction intervals based on the population PK model simulations for that 
weight band are within the targeted 55-162 µg.hr/mL. Additionally, based on the 
available data post the two planned interim analyses, up to two samples will be collected 
in all children enrolled to provide data for the final population PK analysis of TQ to be 
conducted at the end of the study.
Although the volume of blood required for PK sampling is expected to be small, this 
study assessment does not form part of the routine standard-of-care for vivax malaria. It 
is therefore important that serial PK sampling not continue past the point when sufficient 
data have been collected to answer the primary study question. Recruitment to the 
additional cohort of infants aged ≥6 months to <2 years may begin following completion 
of the first interim analysis.
9.4.
Key Elements of Analysis Plan
9.4.1.
Primary Analyses
The primary population PK model based analysis to be performed at the end of the study 
will borrow some information from the adult model. The sparse sampling in pediatric 
subjects is insufficient to independently characterize the absorption phase. Consequently 
the information about absorption from the adult model will be used as prior information 
to feed into the pediatric PK model with the assumption that the absorption processes are 
similar in adults and pediatric subjects. Similarly, other information from the adult PK 
model may also be borrowed in the pediatric model (e.g., distribution). The pediatric 
population PK model will aim to reliably estimate the TQ clearance and thus the 
exposures in the pediatric population [AUC(0-∞) = Dose/CL]. If data permit, other PK 
parameters such as apparent volume of distribution may also be estimated based on 
pediatric data; otherwise, the information will be borrowed from available adult data.
Such model based analyses utilizing prior information from the adult model may be 
implemented using one of the various options available within routinely used population 
PK software such as NONMEM [Beal, 2013] (ICON PLC, USA). The exposures in 
pediatric subjects across various weight bands will be simulated based on the population 
PK model developed from the pediatric PK data. The doses that provide target median 
exposures of 96 µg.hr/mL in each weight band with relevant precision (see Section 9.3.2) 
will be estimated using the population PK model. The details of the approach will be 
described in the study reporting and analysis plan.
The final analysis of the data will include modeling and simulation activity in order to 
provide dosing recommendations for pediatric subjects across different weight bands. 
The weight bands and doses may or may not be similar to the weight bands and doses 
currently proposed in the study. The final recommended dosing schedule across any

58
weight band will aim to provide the average target exposure of 96 µg.hr/mL and will take 
into account the safety and efficacy data from the pediatric study.
9.4.2.
Secondary Analyses
The overall safety and particularly of key endpoints such as gastrointestinal tolerability, 
clinically relevant drops in hemoglobin and incidence of AEs will be assessed.  The 
ophthalmic assessments of visual acuity, keratopathy and retinopathy will be 
summarized.
The recurrence-free efficacy at 4 months will be estimated at the interim and final 
analyses.  The targeted exposure in the pediatric study population is expected to match 
the high level of recurrence free efficacy observed in adults. Although there is no control 
group to compare the background recurrence rates, the overall estimate of recurrence 
rates will help compare the exposure-efficacy response in this study to the observed 
response in the efficacy studies in adults.
If data has been acquired in infants aged ≥6 months to <2 years, it will be included in the 
main PK model and will contribute to the overall assessment of TQ exposure by weight 
band and dose setting in this age band.


Investigator reporting requirements (e.g. reporting of AEs/SAEs/protocol deviations 
to IRB/IEC)

GSK will provide full details of the above procedures, either verbally, in writing, or 
both.

Signed informed consent must be obtained for each subject prior to participation in 
the study

The IEC/IRB, and where applicable the regulatory authority, approve the clinical 
protocol and all optional assessments, including genetic research.  

Optional assessments (including those in a separate protocol and/or under separate 
informed consent) and the clinical protocol should be concurrently submitted for 
approval unless regulation requires separate submission.  

Approval of the optional assessments may occur after approval is granted for the 
clinical protocol where required by regulatory authorities.  In this situation, written 
approval of the clinical protocol should state that approval of optional assessments is 
being deferred and the study, with the exception of the optional assessments, can be 
initiated.
10.3.
Quality Control (Study Monitoring)

In accordance with applicable regulations including GCP, and GSK procedures, 
GSK monitors will contact the site prior to the start of the study to review with the 
site staff the protocol, study requirements, and their responsibilities to satisfy 
regulatory, ethical, and GSK requirements.  

When reviewing data collection procedures, the discussion will also include 
identification, agreement and documentation of data items for which the CRF will 
serve as the source document.
GSK will monitor the study and site activity to verify that the:

Data are authentic, accurate, and complete.

Safety and rights of subjects are being protected.

Study is conducted in accordance with the currently approved protocol and any other 
study agreements, GCP, and all applicable regulatory requirements.
The investigator and the head of the medical institution (where applicable) agrees to 
allow the monitor direct access to all relevant documents
10.4.
Quality Assurance

To ensure compliance with GCP and all applicable regulatory requirements, GSK 
may conduct a quality assurance assessment and/or audit of the site records, and the 
regulatory agencies may conduct a regulatory inspection at any time during or after 
completion of the study. 

In the event of an assessment, audit or inspection, the investigator (and institution) 
must agree to grant the advisor(s), auditor(s) and inspector(s) direct access to all

relevant documents and to allocate their time and the time of their staff to discuss the 
conduct of the study, any findings/relevant issues and to implement any corrective 
and/or preventative actions to address any findings/issues identified.
10.5.
Study and Site Closure

Upon completion or premature discontinuation of the study, the GSK monitor will 
conduct site closure activities with the investigator or site staff, as appropriate, in 
accordance with applicable regulations including GCP, and GSK Standard Operating 
Procedures.

GSK reserves the right to temporarily suspend or prematurely discontinue this study 
at any time for reasons including, but not limited to, safety or ethical issues or severe 
non-compliance. For multicenter studies, this can occur at one or more or at all sites.  

If GSK determines such action is needed, GSK will discuss the reasons for taking 
such action with the investigator or the head of the medical institution (where 
applicable).  When feasible, GSK will provide advance notification to the 
investigator or the head of the medical institution, where applicable, of the 
impending action.

If the study is suspended or prematurely discontinued for safety reasons, GSK will 
promptly inform all investigators, heads of the medical institutions (where 
applicable) and/or institution(s) conducting the study. GSK will also promptly 
inform the relevant regulatory authorities of the suspension or premature 
discontinuation of the study and the reason(s) for the action.  

If required by applicable regulations, the investigator or the head of the medical 
institution (where applicable) must inform the IRB/IEC promptly and provide the 
reason for the suspension or premature discontinuation.
10.6.
Records Retention

Following closure of the study, the investigator or the head of the medical institution 
(where applicable) must maintain all site study records (except for those required by 
local regulations to be maintained elsewhere), in a safe and secure location.  

The records must be maintained to allow easy and timely retrieval, when needed 
(e.g., for a GSK audit or regulatory inspection) and must be available for review in 
conjunction with assessment of the facility, supporting systems, and relevant site 
staff.  

Where permitted by local laws/regulations or institutional policy, some or all of these 
records can be maintained in a format other than hard copy (e.g., microfiche, 
scanned, electronic); however, caution needs to be exercised before such action is 
taken.  

The investigator must ensure that all reproductions are legible and are a true and 
accurate copy of the original and meet accessibility and retrieval standards, including 
re-generating a hard copy, if required.  Furthermore, the investigator must ensure 
there is an acceptable back-up of these reproductions and that an acceptable quality 
control process exists for making these reproductions.

evaluate liver disease; complete Liver 
Imaging and/or Liver Biopsy CRF 
forms.
1.
Serum bilirubin fractionation should be performed if testing is available. If serum bilirubin fractionation is not 
immediately available, discontinue study treatment for that subject if ALT 3xULN and bilirubin 2xULN.. 
Additionally, if serum bilirubin fractionation testing is unavailable, record presence of detectable urinary 
bilirubin on dipstick, indicating direct bilirubin elevations and suggesting liver injury. 
2.
All events of ALT 3xULN and bilirubin 2xULN (>35% direct bilirubin) or ALT 3xULN and INR>1.5, if INR 
measured which may indicate severe liver injury (possible ‘Hy’s Law’), must be reported as an SAE (excluding 
studies of hepatic impairment or cirrhosis); INR measurement is not required and the threshold value stated 
will not apply to subjects receiving anticoagulants
3.
New or worsening symptoms believed to be related to liver injury (such as fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, or jaundice) or believed to be related to hypersensitivity (such as fever, rash or 
eosinophilia)
4.
Includes: Hepatitis A IgM antibody; Hepatitis B surface antigen and Hepatitis B Core Antibody (IgM); Hepatitis C 
RNA; Cytomegalovirus IgM antibody;  Epstein-Barr viral capsid antigen IgM antibody (or if unavailable, obtain 
heterophile antibody or monospot testing);  Hepatitis E IgM antibody 
5.
PK sample may not be required for subjects known to be receiving placebo or non-GSK comparator treatments.)  
Record the date/time of the PK blood sample draw and the date/time of the last dose of study treatment prior to 
blood sample draw on the CRF. If the date or time of the last dose is unclear, provide the subject’s best 
approximation. If the date/time of the last dose cannot be approximated OR a PK sample cannot be collected in 
the time period indicated above, do not obtain a PK sample. Instructions for sample handling and shipping are in 
the SRM.

12.3.
Appendix 3: Definition of and Procedures for Recording, 
Evaluating, Follow-Up and Reporting of Adverse Events
12.3.1.
Definition of Adverse Events
Adverse Event Definition:

An AE is any untoward medical occurrence in a patient or clinical investigation 
subject, temporally associated with the use of a medicinal product, whether or not 
considered related to the medicinal product.

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 medicinal product.
Events meeting AE definition include:

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments (e.g., ECGs, radiological scans, vital signs 
measurements), including those that worsen from baseline, and felt to be clinically 
significant in the medical and scientific judgement of the investigator.

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 prior to the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected 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 this is an intentional overdose taken with possible suicidal/self-
harming intent.  This 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.  However, the signs and symptoms and/or clinical 
sequelae resulting from lack of efficacy will be reported if they fulfil the definition 
of an AE or SAE.

The signs and symptoms and/or clinical sequelae resulting from lack of efficacy will 
be reported if they fulfil the definition of an AE or SAE.  Also, "lack of efficacy" or 
"failure of expected pharmacological action" also constitutes an AE or SAE.


2014N207627_03
CONFIDENTIAL
TAF113577
71
Events NOT meeting definition of an AE include:

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 subject’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 subject’s 
condition.

Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that 
leads to the procedure is an AE.

Situations where 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.
12.3.2.
Definition of Serious Adverse Events
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, etc).
Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, 
at any dose:
a.
Results in death
b.
Is life-threatening
NOTE:
The term 'life-threatening' in the definition of 'serious' refers to an event in which the 
subject 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 hospitalization or prolongation of existing hospitalization
NOTE:

In general, hospitalization signifies that the subject 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 out-patient setting.  Complications that occur during hospitalization are 
AEs.  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 disability/incapacity
NOTE:

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 or prevent everyday 
life functions but do not constitute a substantial disruption
e.
Is a congenital anomaly/birth defect
f.
Other situations:

Medical or scientific judgment should be exercised in deciding whether 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 subject or may require medical or surgical intervention to prevent one of the 
other outcomes listed in the above definition.  These should also be considered 
serious.

Examples of such events are 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
g.
Is associated with liver injury and impaired liver function defined as:

ALT 3xULN and total bilirubin* 2xULN (>35% direct), or

ALT 3xULN and INR** > 1.5.
* Serum bilirubin fractionation should be performed if testing is available; if unavailable, 
measure urinary bilirubin via dipstick.  If fractionation is unavailable and ALT 3xULN 
and total bilirubin 2xULN, then the event is still to be reported as an SAE.
** INR testing not required per protocol and the threshold value does not apply to 
subjects receiving anticoagulants.  If INR measurement is obtained, the value is to be 
recorded on the SAE form.

Recording of AEs and SAEs
AEs 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) 
relative to the event.

The investigator will then record all relevant information regarding an AE/SAE in 
the CRF

It is not acceptable for the investigator to send photocopies of the subject’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 instance, all subject identifiers, with the exception of the 
subject number, will be blinded on the copies of the medical records prior to 
submission of to GSK.

The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information.  In such cases, the diagnosis will be 
documented as the AE/SAE and not the individual signs/symptoms.

Subject-completed Value Evidence and Outcomes questionnaires and the collection 
of AE data are independent components of the study.

Responses to each question in the Value Evidence and Outcomes questionnaire will
be treated in accordance with standard scoring and statistical procedures detailed by 
the scale’s developer.

12.3.5.
Evaluating AEs and SAEs
Assessment of Intensity
The investigator will make an assessment of intensity for each AE and SAE reported 
during the study and will assign it to one of the following categories:

Mild:  An event that is easily tolerated by the subject, causing minimal discomfort 
and not interfering with everyday activities.

Moderate:  An event that is sufficiently discomforting to interfere with normal 
everyday activities

Severe:  An event that prevents normal everyday activities. - an AE that is assessed 
as severe will not be confused with an SAE. Severity is a category utilized for rating 
the intensity of an event; and both AEs and SAEs can be assessed as severe.

An event is defined as ‘serious’ when it meets at least one of the pre-defined 
outcomes as described in the definition of an SAE.
Assessment of Causality

The investigator is obligated to assess the relationship between study treatment and 
the occurrence of each AE/SAE.

A "reasonable possibility" is meant to convey that there are facts/evidence 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 natural history of the underlying diseases, concomitant 
therapy, other risk factors, and the temporal relationship of the event to the study 
treatment will be considered and investigated.

The investigator will also consult the Investigator Brochure (IB) and/or Product 
Information, for marketed products, in the determination of 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 when an SAE has occurred and the investigator has 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 
prior to the initial transmission of the SAE data to GSK.

The investigator may change his/her opinion of causality in light of follow-up

information, amending the SAE data collection tool accordingly.

The causality assessment is one of the criteria used when determining regulatory 
reporting requirements.
Follow-up of AEs and SAEs

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as may be indicated or as requested by GSK to 
elucidate as fully as possible the nature and/or causality of the AE or SAE.

The investigator is obligated to assist.  This may include additional laboratory tests 
or investigations, histopathological examinations or consultation with other health 
care professionals.

If a subject 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 the designated 
reporting time frames.
12.3.6.
Reporting of SAEs to GSK
SAE reporting to GSK via electronic data collection tool

Primary mechanism for reporting SAEs to GSK will be the electronic data collection 
tool

If the electronic system is unavailable for greater than 24 hours, the site will use the 
paper SAE data collection tool and fax it to the Medical Monitor.

Site will enter the serious adverse event data into the electronic system as soon as it 
becomes available.

After the study is completed at a given site, the electronic data collection tool (e.g., 
InForm system) 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 subject or receives updated data 
on a previously reported SAE after the electronic data collection tool has been taken 
off-line, the site can report this information on a paper SAE form or to the Medical 
Monitor by telephone.

Contacts for SAE receipt can be found at the beginning of this protocol on the 
Sponsor/Medical Monitor Contact Information page.

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 above. 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.

Tafenoquine Paediatric Dose Extrapolation
____________________________________________________________
23/04/2014
1. Introduction
Tafenoquine has been dosed in a Phase 2b dose-ranging study in adults with extensive 
pharmacokinetic data for single adult doses of 50, 100, 300 and 600 mg. A population PK 
analysis (to be reported) using a two-compartment model with first order absorption and 
random effects on volume and terminal phase half-life (beta) identified bodyweight to be a 
significant determinant of exposure. The allometric power for clearance was approximately 0.5, 
in contrast to traditional estimates of 0.75. The inclusion of bodyweight allometry into the 
model was highly statistically significant.
Assuming a target exposure equivalent to the adult dose of 300 mg, we propose using 
allometry to optimally select doses and weight bands that provide the best matching of 
paediatric AUC(0-inf) to that of adults. The justification for the selection of 300 mg will be 
discussed elsewhere. The proposal is to use the parameters for the adult model, and assume 
that there are no developmental effects on the apparent clearance of tafenoquine for the age 
(and weight) ranges to be treated.

2. Methods
The adult population pharmacokinetic model used to describe the Phase 2b dose ranging study 
was the standard two-compartment model with first order absorption. Bodyweight is part of 
the model and the full equation takes the form;
(t) = Dose*((BWT/60)**-pBWT)*(A*exp(-Alpha*t) + B*exp(-Beta*t) - (A+B)*exp(-KA*t)).
Bodyweight was centred on 60 kg in accordance with observation from the trial. The dose-
normalized AUC(0-inf) for a 60 kg adult is therefore given by DNAUC(0-inf) = A/Alpha+B/Beta-
(A+B)/KA = 0.316 ug.hr/ml/mg. The only other parameter required to extrapolate AUC(0-inf) 
for other doses and bodyweights is the allometric power, pBWT = 0.5217.
The pharmacokinetic model estimates between-subject variability for parameters A and B, and 
this can be used to derive 95% confidence limits for adult exposure and hence a target 
exposure to be maintained in children. Moreover, the variability in children is solely assumed 
to result from bodyweight, and hence 95% limits for children can also be derived.
We propose up to four weight bands with cut-off points and doses for each weight band. For 
each scenario, we can calculate AUC(0-inf) with 95% confidence limits across the weight range 
0-100 kg. For each scenario, we derive the square error (deviation) from the idealized 300 mg
adult exposure (for a 60 kg subject), then evaluate the root mean square error for the range 0-
100 kg.
In order to evaluate scenarios, we begin with a proposal that has been optimized by trial and 
error. Doses are assumed to be 50, 100, 200 and 300 mg and weight bands are 0-4, 4-16, 16-40 
and >40 kg. In the Phase 2b trials, the lowest recorded weight was 32kg. A cut-off of 30-40 kg is 
therefore reasonable.
To evaluate optimality we could, in principle, minimise the RMSE by changing weight bands and 
doses. In practice this is a hard optimization, so we propose an alternative. Four weight classes 
are defined and generated from uniform random distributions. The lowest dose range is 
defined randomly from 0-100 mg and subsequent doses selected using linear: 150*rand[0,1], 
and multiplicative: 4**rand[0,1] escalations. 100,000 scenarios are simulated and the RMSE 
calculated for each scenario. Optimization is performed manually by selecting the extreme 
(low) RMSE scenarios and comparing with the trial and error proposal. Finally a pseudo-optimal 
solution is presented graphically with a recommendation for dose strengths.
In principle, the full solution is soluble in closed form with integration of the RMSE function by 
dose and weight band in an eight dimensional phase space. The random sampling algorithm, 
whilst not the most efficient, is robust and should therefore be capable of finding very good 
solutions.

3. Results
3.1. Trial and Error
We begin by assuming that a 50 mg dose might be possible for the smallest children, and that 
we should try and avoid dosing on a mg/kg basis greater than 10 mg/kg. Doses are fixed to 50, 
100, 200 and 300 mg, and weight bands were chosen manually and are 0-4, 4-16, 16-40 and 
>40 kg. The predicted AUC(0-inf), complete with dose bands and adult 300 mg target (for a 60 
kg subject) are plotted below. The RMSE for this scenario is an impressive 14.6 ug.hr/ml, 
compared with a target of 95 ug.hr/ml, implying an over/under dosing of approximately 15%.
Figure 5
First Guess Paediatric AUC (0-inf) as a Function of Bodyweight and 
Dose 
3.2. Simulations
We now conduct a simulation of 100,000 scenarios, selected at random with some structural 
components. First, the lowest dose is deemed to be between 0 and 100 mg and is uniformly 
distributed (i.e., the mean will be 50 mg). Second, the increment in dose for each weight band is 
4**rand[0,1] (i.e., the mean fold increase will be two-fold). Finally we assume four uniform 
random weight bands of widths 10, 20, 30 and 20 kg, implying mean cut-offs of 0-5, 5-15, 15-30 
and 30-40 kg, in keeping with the first proposal. These can be varied at will, as can the fold 
changes in dose per weight band.
The histogram below shows the RMSE for AUC(0-inf) compared with target. The dashed red line 
shows the RMSE for the first proposal and it is clearly close to optimal. Some selections will 
clearly under- or over-dose paediatric patients hugely!

3.3. Optimality
Having simulated 100,000 scenarios, the histogram shows the distribution of RMSEs. The 
multiplicative dose escalation tended to produce many scenarios with large over- or under-
dosing, when presented on a semi-log plot (not shown). The additive escalations show a log-
normal distribution. We select the five smallest as a measure of optimality and compare with 
the trial proposal (Scenario 0). The table below shows original proposal compares well, but that 
a smaller RMSE available by tuning doses and weight bands accordingly. It is however entirely 
possible that the small difference in RMSE is of little clinical significance, and this can be tested 
with the exposure-relapse response logistic regression model we have used to analyse the 
efficacy data (not shown).

3.4. Optimal Exposure Prediction
Selecting the scenario with the lowest RMSE from the table and using the weight bands and 
doses for a final simulation of the predicted exposures. This is compared with the target AUC(0-
inf) and range in adults in the Figure below.
Figure 7
Optimal Paediatric AUC (0-inf) as a Function of Bodyweight and 
Dose
3.5. Proposed Paediatric Dose and Weight Bands
We assume that the paediatric formulation is only to be made available in one tablet strength, 
and that selection of dose and weight bands should be close to optimal. Table 5 suggests that a 
low dose of 50 mg and a low weight range of 0-5 kg is optimal. We therefore propose a tablet 
strength of 50 mg that provides for doses of 50, 100, 150, 200 and 250 mg, combined with the 
adult dosage form of 300 mg. Using the weight bands 0-5, 5-10, 10-20, 20-35 and >35 kg, we 
present a near optimal one-tablet dosing nomogram with RMSE 14.0 ug/day/ml (15% error). 
Subjects >35 kg receive the adult dosage form.

Weight Bands 0-5, 5-10, 10-20, 20-35 and >35 kg
Bodyweight has been used as a covariate to predict exposure with an exponent estimated 
from the adult data.  The lowest weight in the adult study was 32 kg, and it is possible the 
exponent, pBWT, although estimated with good precision, may be an underestimate.  The 
conventional value for metabolic processes is 0.75, and we now consider model 
misspecification, should the true value (estimated from paediatric data) fall closer to the 
conventional value.
With all other parameters fixed, the RMSE for the conventional exponent of 0.75 increases to 34 
ug.hr/ml ().  Much of this error is, however, in the 0-5 kg weight range, which will not be treated 
in the proposed study.  Once data is acquired, estimation of exposure in the treated subjects 
using the established population pharmacokinetic model in the first instance, will provide a 
better estimation of the allometric exponent down to 5 kg.

4. Conclusion
A simple closed-form solution that describes the effect of bodyweight on Tafenoquine exposure, 
which has in turn been related to the probability of relapse, has been used to extrapolate adult 
exposure down to paediatric populations. It is assumed that the only determinants of exposure 
are dose and bodyweight, and that the effects of bodyweight scale allometrically from 60 kg 
down to 1kg.
A range of weight bands and doses have been investigated, and these have been optimized 
using random phase space exploration. Simulation of 100,000 possible scenarios shows that a 
weight band of 0-5 kg is prudent, and that a low dose of 50 mg is optimal. If one tablet strength 
is desired for paediatric formulation, we propose 50, with four weight bands. This nomogram is 
very close to optimal, with a RMSE of less than 15% of the target exposure in adults.
Evaluation of model mis-specification shows that the proposed nomogram is robust, with a 
maximum RMSE of 36%. Since most of this error is in the smallest weight band that will not be 
treated in the proposed paediatric trial, and evaluation of exposure is planned after 
approximately 20 subjects have been dosed, the proposal is deemed to be sufficiently robust for 
evaulation in a clinical setting.

Tafenoquine Paediatric Population-PK Trial 
Simulation
____________________________________________________________

1.Introduction
The pharmacokinetics of tafenoquine have been evaluated in adults in a Phase 2b dose-
ranging study. A population PK analysis was used to extrapolate exposure to paediatric cases 
and a weight-based dosing nomogram proposed for the paediatric trial (see Appendix 8).
Having evaluated suitable doses and weight bands, the purpose of this report is to consider 
how the paediatric trial should be designed to best evaluate exposure in a much small 
population whilst still maintain precision in estimation methods.
For the paediatric population we have proposed five weight bands; 0-5, 5-10, 10-20, 20-35 and 
>35 kg, with corresponding doses of 50, 100, 150, 200 and 300 mg. Analysis showed that this is 
a near optimal nomogram for maintaining predicted exposure within 15% of that of adults. 
Design parameters for the paediatric trial to confirm the suitability of this nomogram are; 
number of subjects in each weight band, total number of subjects and sample times.
In the adult study five pharmacokinetic samples were taken over 60 days. This scheme, 
coupled with the large number of subjects, meant that a two-compartment model with first-
order absorption was well-estimated and described the observed data. Allometry was 
integrated into the model allowing for  full paediatric extrapolation.
In this report we consider the effects of sparse sampling and reduced sample sizes. These 
restrictions are necessary on the grounds of practicality; minimising data collection in children 
is an important aim of paediatric extrapolation, but at the same time reduce the ability to 
estimate exposure accurately. Any finalised design should aim to balance sample size, 
sampling scheme and precision of estimation.

2. Methods
To conduct the trial simulation we begin from the adult population PK model incorporating 
allometry. We draw random samples from a distribution of bodyweight and categorise 
according to pre-established weight bands and corresponding doses. Full PK profiles, including 
residual, are generated for each subject. For each design scenario 1000 trial replicates are 
simulated. This superset of data forms the basis for analysis. A variety of sampling schemes can 
then be subsampled and a population PK model fitted to the data for each sampling scheme. 
Once a model is fitted, post-hoc individual estimates of exposure are calculated and compared 
with the true value for each subject. Deviation (Observed - Predicted) is calculated. Finally, the 
Root Mean Square Error (RMSE) is used to summarise the precision of each trial replicate. The 
overall outcome is a distribution of 1000 estimated of RMSEs for each trial design scenario, from 
which a sampling recommendation can be made.
In the Phase 2b analysis, the model used to describe the data was fully parameterised and all 
parameters were estimated with very good precision. In the paediatric trial we are concerned 
with estimation of exposure for the smallest number of subjects (as opposed to evaluation of 
efficacy). This means that the much smaller sample size, say 20 subjects compared with 200, 
may make estimation of all pharmacokinetic parameters challenging. Moreover, sparse 
sampling, particularly when there is no sampling during the absorption phase, makes estimation 
of a fully parametrised model impossible. A number of techniques are possible to overcome this 
challenge ranging from no parameter estimation (assume the adult model is a perfect 
description of paediatric subjects) to a Bayesian analysis with informative priors (using proc 
mcmc) and estimating posterior pharmacokinetic parameters after incorporating the paediatric 
data. For the purposes of this analysis, we will use full estimation for the full dataset and fix 
parameters as necessary for sparse sampled datasets. The final trial analysis may additionally 
make use of Bayesian techniques, but those will not be tested here.

3. Model Simulation
3.1. Pharmacokinetic Model
The Phase 2b adult data was described using a two-compartment model with first-order 
absorption and integral allometry that incorporated weight as a determinant of exposure. 
The model was parameterised in terms of macroconstants, A, B, Alpha and Beta and the full 
equation takes the form;
(t) = Dose*((BWT/60)**-pBWT)*(A*exp(-Alpha*t) + B*exp(-Beta*t) - (A+B)*exp(-KA*t)) + s2.
where s2 is the residual. Parameters A and B are random effects and share the same log-
normal distribution with inter-subject variance s2b1. The terminal elimination rate, Beta, is 
also a random effect with variance s2b2 with no correlation to A and B. The final parameter 
estimates from the adult model are given in the table below. AUC(0-inf) was estimated from 
the macroconstant parameterisation as Dose*((BWT/60)**-pBWT)*(A/alpha + B/Beta -
(A+B)/KA), and clearance calculated from AUC for both population and individual subjects.

A population of 1000 paediatric subjects is simulated for each of 1000 trials based on a log-
normal weight distribution with mean 3.36 and log standard deviation 0.66. This gives a mean 
bodyweight of 28.9 kg and probabilities of <1%, 5%, 23%, 33% and 36% of being in weight bands 
0-5, 5-10, 10-20, 20-35 and >35 kg respectively (see Figure 10 below). From this population 
subjects are then drawn with or without stratification. Since subjects of less than 5 kg will not be 
recruited, stratification only impacts the proportions in bands 2-5. Without stratification, bands 
2 and 5 will be under-represented, which may have consequences for the estimation of 
allometric scaling and hence patient exposure at bodyweight extremes.

Having sampled a suitable population of subjects, the second trial design parameter is sampling 
times. A dense sampling scheme of twelve PK samples; 0.25, 0.5, 1, 2, 3, 4, 7, 15, 21, 29, 60 and 
84 days forms the superset of all possible times. One of the aims of paediatric studies is to 
balance sampling of subjects with precision of exposure estimation. A number of sample 
schemes can be tested ranging from all twelve samples (the base case) down to as few as two or 
three samples (very sparse).
After simulating 1000 trials from the sampled population and PK sampling scheme, non-linear 
mixed-effects modelling can be used to estimate exposure. We use the same adult 
pharmacokinetic model; a two-compartment linear model with first-order absorption. Paediatric 
sparse sampling will typically mean that there are fewer subjects and sparser sampling than 
adult data. For example, sampling subjects from Day 3 means that there will be very limited 
information on absorption and distribution, hence estimation of the absorption and distribution 
rates, KA and Alpha, will not be possible. The low numbers of subjects means that estimation of 
the magnitude of any random effects may also prove difficult. Instead, we propose fixing these 
nuisance parameters to their adult reference values where necessary, whilst estimating other 
parameters of importance to the paediatric population; relative bioavailability compared with 
adults, allometric scaling power for bodyweight and terminal elimination rate, Beta.
Once the model is fitted and parameters estimated, individual estimates of exposure can be 
calculated and compared with the known value (i.e., known in the sense simulated from the true 
parameters for each subject in the trial); the square of the deviance from true AUC(0-inf) 
calculated and the trial summarised by root mean square error (RMSE). A distribution of RMSE 
values across all 1000 simulated trials is a summary measure of the precision of the trial design 
and allows direct comparison of designs.
The primary objective of the paediatric study is to understand and predict the exposure for each 
weight band and compare with the desired target adult exposure of 96 ug.hr/ml for a 300 mg 
dose in a 60 kg adult. The final model can be used to predict exposure for the midpoint of each 
weight band, complete with propagated uncertainty in precision, using the Estimate statement 
in proc nlmixed. These prediction intervals for the final outcome for each trial and their 
properties can then be summarised over all simulated trials to give confidence that the trial 
design is capable of estimating exposure in a wider population of children.
3.2. A Sample Trial Design
3.2.1. Simulated Data
As an example, we consider a sample trial design of 20 subjects with stratification based on 
weight and five subjects per weight band. The simulated weight distribution, including weight 
bands, coupled with exposures for all 20000 subjects are shown in Figure 11. Note that weight 
stratification distorts the expected log-normal weight distribution and that the proportion in 
each weight band is a constant 25%.

3.2.2. Simulated Pharmacokinetic Profiles
We now consider a sparse sampling scheme with pharmacokinetic samples taken on Days 3, 15, 
29. For illustration, we plot data and analysis results from the first nine simulated trials to show 
trial-to-trial variability. Final results and conclusions are drawn from all 1000 simulated clinical 
trials. The full pharmacokinetic profiles for the first nine trials are shown below with sampling 
from 0.5 to 84 days:

Simulated Full Pharmacokinetic Profiles (Trials 1-9) (above)
By way of contrast, with a sampling scheme of only three time points, the analysis dataset for 
this specific trial design looks much less promising, with no data during the absorption and 
distribution phases whatsoever, and a relatively short observation of terminal elimination 
compared with the half-life:

Since the inter-subject variability for the elimination of tafenoquine is low, the half-life, beta 
looks well-defined on a population basis, despite a truncation of sampling at Day 29. This means 
that sampling beyond one month may not be necessary and this analysis is designed to test that 
hypothesis. Multiple sampling scenarios can be tested, but without data during the absorption 
process, estimation of absorption and distribution rates, KA and Alpha, will not be possible.
3.2.3.Non-linear Mixed-Effects Modelling
We know from the adult data with full pharmacokinetic profiles that tafenoquine 
concentrations are well-described by a two-compartment model with first-order absorption. 
The sparse sampling in this example means that estimation of absorption, distribution and 
possibly inter-subject variability will be challenging. Instead, we fix certain parameters to 
those of adults, whilst allowing the model to estimate others. For this example we estimate 
parameters; A (equivalent to an intercept in a linear model), Beta, allometric power pBWT 
and the residual s2. We fix Alpha and the ratio A/B (equivalent to the overall shape of the 
two-compartment profile), and the inter-subject variability s2b1. For simplicity, only a single 
random effect is used in the model to describe variability on A and B equally (as would be 
expected for volume of distribution, V/F). In this model all subjects will have the same 
terminal-phase elimination rate, Beta, despite the data being simulated with variability in this 
parameter, but each subject will have an individual clearance, CL/F and AUC(0-inf) due to the 
random effect. Starting values for estimated parameters are the adult values.
A conventional model diagnostic plot of observed vs. individual predicted (Log) concentration 
(DV vs. iPRED in NONMEM) is shown in the plots below. The first plot shows a representative 
trial, with prediction intervals from proc nlmixed for each data point. The dashed line is the 
line of equality, the solid line a regression of DV vs. iPRED and the shaded region the prediction 
interval for the linear regression. Notice the prediction interval for almost every data point 
includes the line of unity (this interval diagnostoc is not available in NONMEM).
Figure 14
Diagnostic Plot of DV vs. iPRED With Prediction Interval Bars (Trial 
1) (above)
Removing the prediction interval error bars for clarity, we can show the same diagnostic plot for 
the first nine trials. By fixing some of the parameters, the model is able to provide excellent 
predictions in spite of the sparse sampling scheme.

3.2.4. Predicted Exposures
Having estimated the model parameters, proc nlmixed can provide population estimates of 
exposure calculated from the fixed effects. Using the mid-points for each weight band; 2.5, 7.5, 
15, 27.5 and 47.5 kg, and the closed-form expression for AUC(0-inf) given earlier, the predicted 
population mean AUC(0-inf) for the first nine trials by weight class are shown below, complete 
with target 96 ug.hr/ml and the interval 77-120 which represents traditional bounds for 
bioequivalence, complete with 55-162 which is the prediction interval for a 60 kg adult.

Summarising all 1000 simulated trials, shows that the point estimate AUC by weight class for all 
weight bands falls within the 80-125 conventional bounds for bioequivalence. Confidence limits 
for weight bands 10-20 and 20-35 kg may additionally fall within the same bands for some trial 
replicates, which means that formal bioequivalence could be declared (Figure 17) based on 
model predicted exposure. For other weight bands, formal bioequivalence is unlikely without a 
larger sample size.

(above)
One measure of precision is the coefficient of variation (CV) of a predicted parameter. The 
parameterisation used in this modelling requires clearance to be calculated from the 
macroconstants. The CV can however be calculated and summarised over all clinical trials to 
measure trial design performance. The FDA have proposed a target CV of 0.4 as a guide to 
sample size in paediatric trials. This target does not, however, factor in the effects of 
bodyweight on clearance, nor does it take into account the fact that the actual trial replicate will 
have a trial-specific distribution of bodyweights and the model predicted clearance will be a
function of bodyweight; hence predictions of clearance (but not AUC) are required across the 
weight range of a wider population. In the plot below we present the CV distribution by weight 
class. Although this example uses stratifcation by bodyweight, even in the weight class 0-5 kg, 
who were explicitly excluded from the trial, the sample trial design provides acceptable 
precision.

Trials) (above)

A further method of evaluating the performance of a trial, and one that is much less arbitrary 
than a nominal target CV of 0.4, is to consider how well the post-hoc individual exposure 
estimates compare with the (true) exposure for each subject. The root mean square error for 
AUC(0-inf) provides an objective measure of the precision of any trial design, independent of 
bodyweight.

These results show that for the sample trial design the median RMSE for AUC(0-inf) is only 16 
ug.hr/ml (18%), with 90% (5-95th percentiles) of all trials falling in the range 12.1-21.9 ug.hr/ml. 
By fixing suitable parameters to their adult values, even 20 subjects with only three samples per 
subject can give a reasonable estimate of individual and population exposure with less that 20% 
error.
4. Results
We consider the following scenarios; fixed or weight-based stratification; full, sparse or very 
sparse pharmacokinetic sampling; and sample sizes ranging from 4 to 64 subjects in doubling 
steps. The trial design space therefore has multiple dimensions than can be explored. The 
measure of trial performance is RMSE AUC(0-inf), with a lower value being a higher performing 
trial. The goal is not, however, one of optimisation, but evaluation of adequacy. The full trial 
design without stratification, all twelve samples and 64 subjects can be thought of as the 
reference, and all other trial designs considered in this context. In each sampling scenario, the 
number of parameters estimated is set depending on sampling scheme (but not sample size).

Figure 20
Summary Plot of RMSE for All Trial Scenarios (above)
Looking at the plot of RMSE for AUC(0-inf) and the listing of trial results (Table 9), we note the 
effects of sample size are relatively modest, provided we are prepared to fix parameters from 
the adult model. Increasing sample size reduces the trial-to-trial variability, but the median 
RMSE is relatively constant for any given sampling and parameter estimation scheme. Weight 
stratification was tested for all scenarios and has a smaller effect than might be anticipated 
unless the sample size is very small (4-8 subjects), largely because the weight range included is 
still wide and able to demonstrate allometry (estimation of pBWT). Prediction of AUC(0-inf) at 
the lowest weight class 0-5 kg may, however, be improved. Number of PK samples and durations 
of sampling is not significant provided that the terminal phase elimination is sampled 
appropriately. The low variability in terminal half-life means that no random effect is needed to 
describe this data (despite it being simulated with variability).

5.Conclusions
Any paediatric clinical trial with a primary objective of characterising pharmacokinetics should 
aim to balance sample size, precision and extrapolation from adult data. Tafenoquine 
pharmacokinetics in adults are well-characterised which means that extrapolation to children 
should focus on the allometric aspects of bodyweight and relative bioavailability, rather than 
assuming nothing is known. From an estimation perspective, this means that any sampling can 
borrow information from adults effectively, the question being what information to borrow. In 
this analysis we have shown using simulated paediatric clinical trials, that a relatively small 
sample size is sufficient to characterise the exposure of tafenoquine in children provided some 
parameters are fixed to adult values. Moreover, stratification by previously defined weight 
bands during the clinical trial does not appear to offer additional precision, except for very small 
sample sizes.
Fixing some aspects of the model from adults; namely absorption and distribution, allows the 
trial to focus on clearance and exposure. We find that even very sparse sampling with three or 
four plasma samples will be sufficient to estimate exposure in paediatric subjects. In all events, 
this trial simulation exercise shows that the expected precision for reasonable designs will give 
an estimate of paediatric exposure within 15% of the true value, and well below the 40% 
proposed by the FDA. Once approximately 20 subjects have been recruited, an interim analysis 
can be used to make predictions of AUC(0-inf) by weight class and the need for re-estimation of 
the dosing nomogram considered.

Amendment 2
This amendment is global and applies to all centers.  In this amendment a newly-
described risk was added to the Risk Assessment Table, a typographical error was 
corrected in the inclusion criteria regarding approved methods of contraception, and, 
based on results from cohort 1, changes were made to the tafenoquine dose banding 
scheme.  A change was made to the secondary medical monitor.
In addition, the site-specific information in the previous amendment will be carried over 
into this amendment, thus superseding Amendment No. 1.

ADDED TEXT
Ophthalmic assessments will be performed at Center
(Manaus, Brazil) at 
screening and prior to randomization, at Day 120 and at the withdrawal visit, if 
applicable. The Principal Investigator and site ophthalmologist will determine if the child 
is able to comply with the assessments, based on their malaria status and ability to 
reasonably cooperate with the assessments.  Subjects who do not complete the 
ophthalmic examination at baseline, including interpretable retinal imaging, should not 
complete ophthalmic exams at follow-up or withdrawal.  If a subject completes a portion 
of the ophthalmic exams at baseline, only those same exams should be completed at 
follow-up.
9.4.2. Secondary Analyses
PREVIOUS TEXT
The overall safety and particularly of key endpoints such as gastrointestinal tolerability, 
clinically relevant drops in hemoglobin and incidence of AEs will be assessed.
REVISED TEXT
The overall safety and particularly of key endpoints such as gastrointestinal tolerability,

REPORTING & ANALYSIS PLAN SYNPOSIS
Overview
Key Elements of the RAP
Purpose

The purpose of this Reporting and Analysis Plan (RAP) is to describe the 
analyses to be included in the Clinical Study Report for Protocol TAF113577. 
This document will be provided to the study team members to convey the 
content of the interim analyses and Statistical Analysis Complete (SAC) 
deliverables.
Protocol

This RAP is based on the amended protocol [(Dated: 06-Nov-2018) of study 
TAF113577 [GSK Document Number 2014N207627_03, 2018] and eCRF 
Version 1.
Primary 
Objective

To evaluate the pharmacokinetics (PK) of tafenoquine (TQ) in children and 
adolescents aged ≥2 years to <16 years (weighing ≥5 kg) with P. vivax in order 
to identify appropriate doses that achieve a similar exposure to that of the 
tafenoquine adult dose of 300 mg.
Primary 
Endpoint

AUC(0-∞) of TQ by weight band from a population PK model in pediatric 
subjects aged ≥2 years to <16 years (weighing ≥5 kg).
Study 
Design

TAF113577 is a prospective, open-label, multicenter, non-comparative, single-
arm study. All subjects will receive Chloroquine (CQ) and open-label TQ.

Potential subjects who are slide-positive for P. vivax will be started by the site on 
off-study CQ per local/national guidelines.  Eligible subjects will also receive TQ, 
given as a single dose on Day 1.  All study medication should be taken with 
food.  After the treatment period, subjects will attend up to 7 follow-up visits 
through Day 120.

Approximately 240 subjects aged <16 years with P. vivax malaria will be 
screened to achieve 60 enrolled subjects.  

A subject is considered to have completed the study if they attend all treatment 
and follow-up visits.

An interim analysis will be conducted once sufficient data from 16 subjects is 
available to assess PK and safety parameters. If needed, a second interim 
analysis may be conducted after a total of 32 subjects have enrolled.

Initially, subjects ≥2 years to <16 years of age will be enrolled into the study.  
Recruitment to an additional cohort of infants aged ≥6 months to <2 years 
(weighing ≥5 kg) may begin following completion of the first interim analysis.  
This lower age cohort are included as part of the 60 completed subjects.
Planned 
Analyses

Up to two interim analyses (at 16 and 32 subjects) have been planned so that
the initially planned four PK samples per subject can be reduced to a minimum 
of two PK samples. 

Recruitment will continue for safety data accumulation until 60 subjects are

Overview
Key Elements of the RAP
enrolled.

All decisions regarding final analysis, as defined in this RAP document, will be 
made prior to Database Freeze of the study data. 
Analysis 
Populations

Safety Population: all subjects who received at least one dose of study 
medication. 

Primary PK Population: all subjects with at least one PK sample taken at Days 
3, 15, 29 or 60. This population will be used for the primary PK analysis to 
evaluate TQ exposure.

Microbiologic-Intent-To-Treat (mITT) population: All subjects who received a 
dose of study treatment (tafenoquine) and have microscopically-confirmed vivax 
parasitemia at baseline.
Hypothesis

There are no hypotheses tested in this study
Primary 
Analyses

The primary population PK model-based analysis to be performed may borrow 
some information from the adult model as appropriate. For example, the sparse 
sampling in a limited number of pediatric subjects may be insufficient to 
independently characterize all the population PK parameters e.g. the absorption 
phase. Consequently the information about absorption from the adult model may 
be used as prior information to feed into the pediatric PK model with the 
assumption that these processes are similar in adults and pediatric subjects.
The pediatric population PK model will aim to reliably estimate the TQ clearance 
and thus the exposures in pediatric population. The clearance estimate for each 
subject generated from the model-based analysis will be used to determine the 
subject’s TQ AUC(0-∞) [AUC(0-∞) = Dose/CL].”
Secondary 
Analyses

Relapse-free efficacy will be summarized descriptively. 

Safety data, including data related to gastrointestinal tolerability, clinically 
relevant drops in hemoglobin and incidence and severity of AEs, will be 
presented in tabular format and summarized descriptively according to GSK’s 
Integrated Data Standards Library (IDSL) standards.

SUMMARY OF KEY PROTOCOL INFORMATION
2.1.
Changes to the Protocol Defined Statistical Analysis Plan
Three additional analysis populations have been defined in this RAP:
o
Screened
o
Enrolled
o
Microbiological ITT (MITT)
The definitions are provided in Section 4. 
The efficacy endpoint was called recurrence free efficacy in the protocol, to keep in line with other 
GSK studies in the project this will be referred to as relapse free efficacy throughout this document. 
The window in which to confirm parasite clearance has been extended from the Day 8 visit to on or 
before the Day 29 visit to allow for missed and unscheduled visits which would represent 
clearance.

Study Design
Overview of Study Design and Key Features
Design
Features

An open-label, multicentre, non-comparative, single-arm study. This 
pediatric PK bridging and safety study will test appropriate doses of TQ in 
pediatric subjects selected to achieve similar levels of exposure observed 
in adults treated with 300mg TQ.    

The study will recruit a target of 60 subjects. The duration of the study is 
120 days; study treatment on Day 1, followed by seven follow-up visits on 
Days 3, 8, 15, 29, 60, 90 and 120. 

Pharmacokinetic samples will be collected in order to achieve the primary 
objective of the study. However, in order to minimize distress in this 
pediatric population, a sparse sampling scheme will be used to reduce the 
frequency and volume of blood collected and a population PK modelling 
and simulation approach will be utilized. Furthermore, up to two interim 
analyses have been included in this study, so that full PK sampling can be 
reduced as soon as sufficient data have been collected. 
Dosing
This is an open-label, single arm study, and all subjects will receive CQ and TQ.  
Subjects will be dosed based on weight, with the goal to achieve a median TQ 
exposure of 96 µg.h/mL, the median exposure observed in adults following 
administration of a 300 mg dose of TQ.  The TQ doses presented in Table 2 below 
were selected using a population PK model based on adult data and incorporation 
of allometric scaling.  The doses prior to Protocol Amendment 1 are given which 
relate to the first interim analysis, together with the doses post Protocol 
Amendment 1 used in the second interim and final analyses.

The single dose of TQ will be administered at the investigator site. Subjects >35 kg 
have the choice of taking the TQ adult tablet or the TQ pediatric tablet. All study 
medication should be administered with food. If the subject vomits within 1 hour 
following dosing, a repeat dose should be given. If a subject sequentially vomits 
two doses of study medication he/she will be considered intolerant to study 
medication. These subjects will be withdrawn from study medication and be given 
appropriate rescue medication.

Assignment

This is an open label study. All subjects will receive TQ dose according to the 
baseline weight.
Interim 
Analysis
Up to two interim analyses have been planned so that serial but sparse PK 
sampling (i.e., 4 PK timepoints) may be reduced at the earliest opportunity.

PLANNED ANALYSES
3.1.
Interim Analyses
Up to two main interim analyses have been planned so that serial but sparse PK sampling (i.e., 4 
PK timepoints) may be reduced at the earliest opportunity.  The first interim analysis will take place 
after a total of at least 16 subjects in the main cohort have PK evaluable data or 12 months post 
study initiation, whichever comes first. The second interim analysis will take place after a total of at 
least 32 subjects in the main cohort have evaluable PK data or at 24 months post study initiation, 
whichever comes first. The second interim analysis will take place only if serial but sparse PK 
sampling is continued after the first interim analysis.
The interim analyses will be performed after the completion of the following sequential steps:
1.
All required subjects (i.e. 16 or 32 subjects) have PK evaluable data as defined in the protocol
(or 12/24 months post study initiation).
2.
All required database cleaning activities have been completed and interim database release 
and database freeze has been declared by Data Management.
If it is found that due to insufficient number of children being enrolled in the lowest weight band(s) 
the prediction intervals are wider in that lowest weight band, then further serial (but sparse) 
sampling may be limited to the children being enrolled in the lowest weight band. The analyses will 
then be repeated after next set of 4 subjects and so on until the TQ PK for that weight band are 
adequately characterized and the 95% interval within the targeted 55-162 µg.hr/mL. 
See Appendix 12 for details about the population pharmacokinetic analysis.
The correlation between TQ PK data from venous sampling and capillary microsampling will be 
evaluated. Based on the emerging data, if deemed appropriate, further PK sampling of TQ in 
pediatric subjects will be limited predominantly to capillary microsampling to reduce the PK 
sampling burden on this highly vulnerable population. Agreement will be evaluated based on 
correlation and Bland-Altman analyses. Further details will be documented in the TAF113577 
Interim Analysis Charter.
The decision to enroll subjects aged ≥6 months - <2 years will be based on a review of exposure 
data as well as of safety results from the first interim analysis. Particular attention will be paid to 
the reporting of adverse events related to decreases in hemoglobin (Hb), methemoglobin (metHb) 
levels and increases in key laboratory parameters. The review and decision-making process for 
inclusion of the ≥6 months - <2 years cohort will be outlined in detail in the TAF113577 Interim 
Analysis Charter.
At each interim analysis a review of all available outputs will be performed and decisions made 
regarding the continuation of the study as pre-planned. Potential changes to the study could 
include stopping the study based on safety concerns or adjusting dosing regimens. Further details 
will be documented in the TAF113577 Interim Analysis Charter.

PRIMARY PK AND STATISTICAL ANALYSES
7.1.
PK Analyses
7.1.1.
Overview of Planned PK Analyses
The primary efficacy analyses will be based on the primary PK population, unless otherwise 
specified.
The primary population PK model based analysis to be performed at the end of the study may
borrow some information from the POP PK model developed from the systemic TQ PK data from 
the dose ranging Phase 2B study (TAF112582). For example, the sparse sampling scheme in 
pediatric subjects is likely to be insufficient to independently characterize all the population PK 
parameters e.g. the absorption phase. Consequently, the information about absorption from the 
adult model will be used as prior information to feed into the pediatric PK model with the 
assumption that the absorption processes are similar in adults and pediatric subjects. Similarly, 
other information from the adult PK model may also be borrowed in the pediatric model (e.g., 
distribution). Additionally, any impact of formulation differences from Phase 2B study (TAF112582) 
and emerging data from the Part 2 of TAF112582 and TAF116564 may be utilized to inform model 
development. The pediatric population PK model will aim to reliably estimate the TQ clearance and 
thus the exposures in the pediatric population [AUC(0-∞) = Dose/CL]. If data permit, other PK 
parameters such as apparent volume of distribution may also be estimated based on pediatric 
data; otherwise, the information will be borrowed from available adult data.
Such model based analyses utilizing prior information from the adult model may be implemented 
using one of the various options available within routinely used population PK software such as 
NONMEM [Beal, 2009] (ICON PLC, USA). The exposures in pediatric subjects across various 
weight bands will be simulated based on the population PK model developed from the pediatric PK 
data. The doses that provide target median exposures of 96 µg.hr/mL in each weight band will be 
estimated using the population PK model. The details of the approach are described in Appendix 
12 of this study reporting and analysis plan.
The final analysis of the data will include modelling and simulation activity in order to provide 
dosing recommendations for pediatric subjects across different weight bands. The weight bands 
and doses may or may not be similar to the weight bands and doses currently proposed in the 
study. The final recommended dosing schedule across any weight band will aim to provide the 
average target exposure of 96 µg.hr/mL and will take into account the safety and efficacy data 
from the pediatric study.
Full details of data displays being presented are provided in Appendix 12.


CONFIDENTIAL
TAF113577

7.1.2.
Planned PK Statistical Analyses
A population pharmacokinetic (POP PK) model based approach will be utilized to analyse the TQ 
exposure data from this study. The POP PK model based on adult TQ systemic exposure data was 
utilized to predict pediatric doses with allometric scaling.  Interim analyses will be conducted to 
estimate the systemic exposure in pediatric subjects across different weight bands. Based on that 
outcome, doses across weight bands may be modified or continued as is. The serial but sparse 
sampling may be further reduced post confirmation of exposure across weight groups as 
appropriate. The final analysis of all exposure data from this study will be conducted to formulate a 
final dosing recommendation for TQ in pediatric population. The technical details of the POP PK 
analysis are described in detail in Appendix 12.

8.2.1.1.
Adverse Events
Counting of Adverse Events (AEs) will be based on the number of subjects – not the number of 
AEs. For example, if a subject reports the same AE on three occasions within the relevant time 
interval, that AE will only be counted once.   If a subject experiences the same AE (i.e. same 
preferred term (PT)) more than once, they are counted only once under the count for the preferred 
term.  If a subject experiences more than one AE in a particular System Organ Class (SOC), they 
will only be included once in the count for the SOC, but will appear in the count for each 
appropriate preferred term within the SOC.  Therefore, the sum of the numbers of subjects with 
each preferred term event within a SOC may exceed the total number of subjects with at least one 
event.  For the summary of AEs by maximum intensity, subjects who experience the same event 
several times with different intensity will only be counted once with the maximum intensity. 
Only treatment emergent AEs (TEAEs) will be presented as all subjects receive study medication 
on Study Day 1.  TEAEs are defined as AEs with an onset date and time on or after that of the start 
of first dose of study medication (including CQ).
The recurrence of P. vivax malaria and any associated signs and symptoms are recorded as 
Disease Related Events (DREs) and will not be included in the AE data displays, but will be listed 
separately.
Adverse Events will be summarized by dose group and overall as specified below and in Appendix 
15: List of Data Displays, and presented in order of descending frequency. Table 3 provides an 
overview of the planned analyses, with further details of data displays being presented in Appendix

Individual profile plots for all subjects at each interim analysis. For SAC, if a subject has a >30g/L
or ≥30% decline from baseline hemoglobin or is found to be G6PD deficient, a hematological
profile plot will be produced for the subject. This will display their hemoglobin, absolute reticulocyte, 
methemoglobin and bilirubin results (total and indirect bilirubin on same plot) at each visit.  The 
subject ID, treatment group, sex, age, weight and G6PD status should be included as a header for 
each subject’s plot.

Overview of Planned Pharmacokinetic Analyses
The pharmacokinetic (PK) analyses will be based on the Pharmacokinetic population, unless 
otherwise specified.
8.5.2.
Drug Concentration Measures
Refer to Appendix 5: Data Display Standards & Handling Conventions (Section 10.5.3 Reporting 
Process & Standards).
8.5.3.
Pharmacokinetic Parameters
PK parameters will be estimated based on POP PK model. See Appendix 12 for more details.
8.5.4.
Population Pharmacokinetic (PopPK) Analyses

The primary goal of this analysis is to characterize the population pharmacokinetics of 
tafenoquine (TQ) administered orally in subjects with P. vivax malaria.

o
The influence of subject demographics, baseline characteristics, including disease activity, 
and co-medication on the pharmacokinetics of TQ in this population will be investigated. 

A summary of the planned population pharmacokinetic analyses are outlined below:
o
Drug plasma concentration-time data will be subjected to nonlinear mixed effects 
modelling using the program NONMEM to develop a population PK model.  
o
Individual post-hoc estimated PK parameters will be summarised descriptively.  
o
To support this analysis a NONMEM data file will be generated.

Evaluation of Microsampling
The relationship between venous blood sampling concentrations and capillary microsampling 
concentrations will be explored using the PK population. 
A scatterplot comparing the venous blood plasma concentrations and the microsampling blood 
concentrations for all subjects, at all timepoints will be produced. In addition, the correlation 
between the methods will be calculated and presented in the same plot. The correlation will be 
calculated separately for each quartile, according to the concentration range observed. 
To quantify the level of agreement between the blood sampling methods, a Bland-Altman plot will 
be produced [Bland, 1999]. The plot will display average concentration (x-axis) versus the 
concentration ratio (microsampling concentration/venous concentration) (y-axis). The following 
reference lines will be included in the plot
-
Mean concentration ratio (bias)
-
Mean concentration ratio ± 5% (interim analysis 1 only)
-
Mean concentration ratio ± 15% (interim analysis 2 and SAC only)
-
Limits of agreement calculated as: mean concentration ratio ± 1.96 x SD

For all data summarised by visit, the nominal visit description will be used. Unscheduled and 
withdrawal visit data will be slotted into a scheduled visit window, but the data will only be included 
in summaries and figures if no scheduled visit exists within the window. If there are multiple 
assessments within the same window which are not unscheduled visits, the earliest results will be 
used in the summaries. If only unscheduled visits are included in the same window, the earliest of 
these results will be used in summaries and figures.
For derivations of the maximum/minimum value/change post-baseline, then all data will be 
considered, regardless of whether or not it slotted to a scheduled window.

Multiple Measurements at One Time Point

If there are multiple assessments within the same window which are not unscheduled visits, 
the earliest results will be used in the summaries. All values will be listed. 

Subjects having both High and Low values for Normal Ranges at any post-baseline visits 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

Study Day 1 is defined as the day the dose of study medication was taken. 

Study Day >1 calculated as the number of days from study Day 1 date:

Ref Date = Missing                       → Study Day = Missing 

Ref Date < Study Day 1 date   → Study Day = Ref Date – study Day 1 date

Ref Data ≥ Study Day 1 date   → Study Day = Ref Date – (study Day 1 date) + 1    
Cohort

A subject’s cohort can be determined based on the date of study medication as follows:

Cohort 1 – Date of study medication <05-Jan-2018

Cohort 2 – Date of study medication ≥05-Jan-2018 and <26-Feb-2019

Prior and Concomitant Medications

Medications will be coded using the latest version of GSK Drug.

Prior medications = medications taken up to 30 days before the date and time of the first dose 
of study medication.

Any medications with stop dates earlier than 30 days will not be reported in tables and listings.

Concomitant medications = medications with start date and time on or after the start date and 
time of the dose of study medication (Study Day 1). Medications, with the exception of 
chloroquine, taken prior to the study and continuing during the study will be summarised as both 
prior medications and concomitant medications.

All subjects were expected to take chloroquine prior to the start of study medication, and often
continuing after the start date of study medication. The number and percent of subjects taking 
prior chloroquine will be summarised separately to other prior medications. If chloroquine 
treatment is started after the start of study medication, e.g. to treat a relapse, this should be 
reported in the same way as other concomitant medications. All chloroquine data (prior and

concomitant) will be included in the listing of prior and concomitant medications.

See Section 10.7.2 for the handling of missing and partial dates.
Treatment Compliance and Exposure

All study medication will be administered at the investigator centre in the presence of the 
Investigator or study nurse, and ingestion confirmed. 

On the day of dosing, a subject will be classified as compliant with daily administered dose if 
they do not vomit the initial dose or if they are successfully re-dosed.

A subject is considered to be compliant in clinic if they retain all study medication given to them.

Subjects who were entered but did not report a treatment start date will be categorised as 
having zero doses.

Study treatment consists of a single dose so duration of exposure will not be calculated.
G6PD enzyme activity as a percentage of site median

Safety
Adverse Events

All AEs reported up to and including the Day 120 visit following enrolment of a subject into the 
study will be documented.

These will be recorded and coded using the current version of Medical Dictionary for Regulatory 
Activities (MedDRA). All terms applied will be reviewed by a GSK physician prior to database 
freeze. If any malaria related coded terms are considered to have lost useful information in the 
coding step (e.g., if a verbatim term of ‘Plasmodium vivax malaria’ is mapped to ‘malaria’), 
he/she will recommend a study-specific code, which will be documented.

Treatment emergent AEs are defined as AEs with an onset date and time on or after that of the 
start of first dose of study medication (including CQ).

AEs with entirely missing or unknown start dates will be assumed to be treatment emergent for 
reporting. AEs where the start date is equal to that of study medication, but where the start time 
is unknown will also be assumed to be treatment emergent. AEs with missing end dates are not 
anticipated to affect reporting.

If the grade/intensity is missing for an AE, it will be considered severe/Grade 3 if an AE, or 
Grade 4 if an SAE and the subject is alive, or Grade 5 if an SAE and the subject dies (i.e. the 
highest intensity possible) for the summary of AEs by maximum intensity.

See Section 10.7.2 for more information on missing and partial dates.

Common AEs are those occurring in ≥10% of subjects in any treatment group.

The recurrence of malaria and any associated signs and symptoms are recorded as Disease 
Related Events (DREs) and will not be classified as AEs.

The GSK clinical team will review terms that qualify as potentially hematologically related.
Laboratory Parameters

If a laboratory value which is expected to have a numeric value for summary purposes, has a 
non-detectable level reported in the database, where the numeric value is missing, but typically 
a character value starting with ‘<x’ or ‘>x’ is present, the number of decimal places of x will be 
used to determine how much to add or subtract in order to impute the corresponding numeric

Efficacy
Relapse free efficacy at 4 months

Relapse is defined below based on a positive blood smear with or without vivax malaria 
symptoms. 

A subject will be considered to have demonstrated relapse free efficacy for the purpose of the 
efficacy analysis if all of the following are true (also described in Figure 1):

Subject is slide positive for P. vivax (per slide or source documents) at baseline. 

Subject demonstrated initial clearance of P. vivax parasitemia. This is defined as a negative 
slide at or before the Day 29 visit. Subjects who do not meet this criteria will be censored, 
with time to relapse = 0 days.

Subject is not slide-positive for P. vivax at any assessment prior to or on Study Day 130
following initial parasite clearance. Subjects who are slide-positive for P. vivax will be 
classified as relapses, with time to relapse = (date of first positive slide) – (date of Study 
Day 1) days.

Subject did not take a concomitant medication with anti-malarial activity at any point 
between Study Day 1 and their last parasite assessment (up to and including Study Day 
130). A list of all concomitant medications will be reviewed by a GSK clinician prior to 
unblinding the study, and classified accordingly. Subjects who did take a drug with anti-
malarial activity but never had a positive asexual P. vivax parasite slide after initial 
clearance will be censored, with time to relapse censored at (date of last negative parasite 
assessment prior to concomitant medication start) – (date of Study Day 1). If a subject has 
not had a negative assessment prior to the concomitant medication start date, they will be 
censored at 0 days.

Subject is parasite-free at 4 months. This is defined as a negative asexual P. vivax parasite 
slide at the first parasite assessment performed on or after Study Day 110 (up to and 
including Study Day 130).   

Subjects who do not have a positive asexual P. vivax parasite slide following initial clearance 
but where the final parasite assessment occurred before Study Day 110 will not have been 
classified by the preceding rules.  These subjects will be considered to be censored, with time 
to relapse censored at (Date of final parasite assessment) – (date of Study Day 1).

If a subject has a relapse outcome and a censored outcome, they will be considered to be a 
relapse, even if the time point of the relapse is later than the time point of censoring. For 
example, a subject who took a medication with anti-malarial activity at Study Day 32, but 
remained parasite-free after initial clearance until Study Day 68 will be treated as a relapse at 
Study Day 68.

Appendix 13: Population Pharmacokinetic Analyses
10.13.1.
Introduction
The purpose of the data analyses outlined in this document is to characterise the systemic 
exposure of Tafenoquine (TQ) administered as a single dose to pediatric subjects with P. vivax
malaria with a model based population pharmacokinetic (POP PK) approach. The influence of 
subject demographics, baseline characteristics and any other relevant covariate on the PK of TQ in 
pediatric subjects with malaria will be investigated to identify a dose regimen that provides 
systemic TQ exposure across various weight bands in pediatric subjects similar to that in adult 
population.
Given the small subject numbers in this study, and the sparse nature of PK sampling, a model-
based population PK analysis using non-linear mixed effects is a robust approach for assessing the 
PK of TQ in the pediatric population.
10.13.2.
General Considerations For Data Analyses and Handling
10.13.2.1.
Software
Programming will be performed in a HARP™environment using SAS Version 9 or a later release 
and S-Plus Version 7 or later release. The population PK analysis will be completed using 
NONMEM software, Version 7 (ICON Development Solutions). Data set handling, graphical 
analysis and post-processing of table files will be performed with R Version 3 or later. The 
platform(s), operating system(s), Fortran compiler and any other software used will be described in 
the study report. 
10.13.2.2.
Data Set Preparation
POP PK analysis with NONMEM needs the data to be arranged in a specific format along with a 
number of indicator variables integral to the software. A summary of the dataset specifications, 
indicator variables and their description are given in Section 10.13.6. Variables included in the final 
data set will depend upon the best fit population model(s) and influential covariate(s) in this 
population.  Therefore all indicator variables may not be included in the final model. If data sets are 
modified or reformatted over the course of the analysis, the file name of each version of the data 
set will be unique. For each generated data file, the source file and the SAS orR/S-Plus script file 
used for data manipulation will be archived.
The POP PK dataset will be generated on multiple occasions as the study progresses to support 
the planned interim analyses - up to two main interim analyses are currently planned. Any dataset 
generated will include all available evaluable TQ PK data up to that time. The dataset aggregation 
and initial modelling setup work may begin earlier than the planned interim analyses to aid any
pre-programming, preliminary structural model establishment and generation of simulation and 
graphing scripts. 
Any deviations from the analysis plan will be described in detail in the study report.


CONFIDENTIAL
TAF113577
53
10.13.2.3.
TQ Population PK dataset
For the TQ population PK analysis, patient demographic data (e.g. gender, age, weight, body mass 
index (BMI)), treatment, dosing and sampling dates and time will be extracted from the study 
database and merged with TQ plasma concentration data extracted from SMS2000 for the TQ PK 
population. The POP PK analysis compliant data file will be produced by or under the direct 
auspices of the programming support within the Clinical Statistics or Clinical Pharmacology, 
Modelling and Simulation groups, GlaxoSmithKline. 
Due to the small study size and sparse nature of the PK sampling schedule, data from the previous 
adult studies with more extensive sampling (e.g. the Phase 2B dose ranging study TAF112582) 
may be included to stabilise the structural model as deemed appropriate. SAS or R may be used to 
merge the pediatric TQ PK data with adult TQ PK data. All such POP PK dataset processing 
scripts will be archived. 
10.13.2.4.
Archival Of Data Sets
Data sets, R-script used for data manipulation and/or graphics, NONMEM control stream files, 
NONMEM output files, NONMEM output processing programs and files obtained from processing 
of NONMEM output will be archived.
10.13.3.
Handling of Missing Data
10.13.3.1.
PK Data
If dosing and/or sampling times are missing, the relevant concentrations will be deleted from the 
analysis dataset and summarized in a deletion record listing by the programmer. Samples listed as 
having no sample (NS), no result (NR) or insufficient sample (IS) will be excluded from the PK data 
set and also included in the deletion record listing.  
10.13.3.2.
Subject Demographics
Imputations of any continuous covariate value will only be performed if the variable is missing for 
less than 10% of the subjects and the variable is deemed necessary for the modelling effort. For 
continuous covariates, missing values for an individual subject will be imputed as the gender-
specific median value for the study. Any changes to the imputation methods will be justified and 
documented. If the percentage of missing data is greater than 10%, the variable will only be 
evaluated in exploratory graphical displays. There may not be imputation for any missing 
categorical covariate value.
10.13.3.3.
Handling of Data Below the Lower Limit of Quantification
TQ concentrations below the respective lower limit of quantification (LLQ) for the bio-analytical 
assay will be reported as NQ (Below Quantification Limit, BQL). All NQ values will be set to “.”in the 
population PK dataset. Individuals with all plasma concentrations reported as NQ will be included 
in the data set. However, a likelihood estimation method (M3) for these BQL data will not be 
implemented (Ahn et al) and the BQL observation rows will be ignored during model building.


CONFIDENTIAL
TAF113577
54
10.13.3.4.
Handling of Outliers
Concentration results inconsistent with the expected PK behaviour of TQ may be excluded from 
the modelling after investigation about possible sampling/labelling errors.  Outlier detection will be 
based initially on visual examination of individual and pooled PK profiles. However, the final model 
may be retested with and without inclusion of these data points. The exclusions will be listed in the 
report.
10.13.4.
Population PK Modelling
The POP PK analysis will be based on non-linear mixed-effects models. The analysis will be 
performed as recommended by the FDA, Population Pharmacokinetics Guidance for Industry
document [FDA, 1999]. Mixed-effects models describe the influence of both fixed effects and 
random effects on a dependent variable, e.g. concentration or clinical endpoint. Fixed effects, 
THETA () in NONMEM notation, are factors that are either measured or controlled.  Random 
effects include residual error (ERR), epsilon (ε) in NONMEM notation, and between subject random 
effects, ETA () in NONMEM notation.
Population mixed effects models include the basic components:

The structural model, which predicts the plasma concentration as a function of time and 
dose.

The covariate model component, which describes the influence of fixed effects (e.g. 
demography, disease, treatment, concomitant medication) on the PK model population 
parameters.

The between-subject variance component, which describes the inter-individual variation in 
PK parameters (after “correction” for fixed effects).  Inter-individual or between-subject 
variability will be initially modelled using an exponential error model.

The residual error model components describe the underlying distribution of the error in 
the measured PK variable. Various error models are available to choose from based on 
emerging data. The goodness-of-fit plots and any potential biases therein will aid selection 
of an appropriate residual variability model e.g., additive, proportional, additive plus 
proportional or exponential.
A visual predictive check (VPC) method will be utilized to evaluate the adequacy of the final model, 
including the effects of statistically significant covariates. Statistics of interest including mean
derived PK parameter values will be calculated from this model based analysis. 
10.13.4.1.
TQ Population PK Analysis
10.13.4.1.1.
Base Model
A structural model for the available TQ PK data from pediatric population will be built first, including 
error models. Initial selection of the simplest structural POP PK model, to be used as a valid base 
model, will be based on but not limited to the minimum objective function value, plausibility of 
parameter estimates, goodness-of-fit plots and VPC plots.  The most appropriate between-subjects 


CONFIDENTIAL
TAF113577
55
variability and residual error model, will be identified and the resulting model called a BASE model. 
If needed different estimation methods available in recent NONMEM versions may be tested to 
characterize the sparse PK data.
Due to the sparse PK sampling and few subjects, only key parameters of interest may be 
estimated (e.g. clearance – TQ CL) as data permit. Other PK parameters (e.g. absorption rate –
TQ KA) may be fixed to the population estimates obtained from the TQ POP PK analysis of data 
from the dose ranging Phase 2B study in adult population (TAF112582). The random effect on 
these parameters may be estimated as data permit. If needed, the TQ PK data from those studies 
may also be included in the analyses dataset to provide stability to the POP PK structural model.
Any deviations from such planned analysis will be described in detail in the study report.
10.13.4.1.2.
Covariate Inclusion
Once a BASE model has been identified, covariates will be added as necessary, using predefined 
strategy.  Currently, the doses selected for the TEACH study are based on allometric scaling of 
clearance based on weight. Thus while not mandatory, patient weight is likely to be included as a 
significant component of the structural model and will be primarily guided by emerging pediatric PK 
data. While unlikely that other covariates will be included in the model due to small study size, the 
effects of subject demographic characteristics (e.g. age, body mass index (BMI)) may be examined 
as data permit. The final model shall have no redundant factor but the strategy shall ensure that no 
significant factor is missing. 
Covariate model building may be undertaken once data from all pediatric patients is available at 
the end of the study. The covariate modelling approach will consider the step-wise process 
consisting of a forward and a backward selection procedure as appropriate based on emerging 
data. 
10.13.4.1.3.
Final Model
The model that has evaluated the impact of any key clinically relevant covariates (weight and other 
covariates) and adequately describes the observed data will be called the FINAL model and used 
for simulations. 
The FINAL TQ POP PK model will be used to predict the systemic TQ exposure across various 
weight bands in pediatric population. The POP PK model based individual post-hoc TQ CL 
estimates will be utilized to calculate the individual TQ exposure [AUC(0-∞) = Dose/CL].  At every 
interim analysis, the 95% prediction interval of AUCs based on the simulation with the population 
pharmacokinetic model will also be generated for the mid-point of each weight band (at a 
population level). See details in Section 3.1. 
10.13.4.2.
Interim TQ POP PK Analysis
Based on the data from the dose finding Phase 2B study in adult subjects with P. vivax malaria 
(TAF112582), initial POP PK modelling and simulation (M&S) exercise suggested that 
approximately 16 pediatric subjects would provide sufficient information to adequately characterize 
the TQ PK in this population. Hence the POP PK M&S activity will be undertaken after a total of at 
least 16 subjects have evaluable PK data or 12 months post study start whichever comes first. In 


CONFIDENTIAL
TAF113577
56
case these data are insufficient to adequately characterize the POP PK in the pediatric population, 
the sparse serial PK sampling will continue and the next M&S exercise will be performed after a 
total of at least 32 subjects have evaluable PK data or 24 months post study initiation, whichever 
comes first. 
At every interim analysis, the 95% prediction interval of AUCs based on the simulation with the 
population pharmacokinetic model will be generated for the mid-point of each weight band (at a 
population level).  If this interval lies within the AUC range of 55-162 µg.hr/mL for the mid-point of 
each weight band, serial (but sparse) sampling can be reduced for any subjects enrolled further. 
These bounds were chosen because 95% of adult subjects dosed with the efficacious dose of 300 
mg TQ in part 1 of Study TAF112582 had an AUC that fell within this range and the lower bound is 
consistent with the clinically relevant breakpoint of 56.4 μg.h/mL for the adult Phase IIb data 
(TAF112582 Part1). Recruitment will continue for safety data accumulation with these subjects 
having a PK assessment at two timepoints.
The first set of 16 subjects to be enrolled in the study will be 2 or more years old. Based on the 
interim analyses of data from these 16 subjects, if TQ is well tolerated without any significant safety 
concern the enrolment will be opened to infants 6 months and older. If the 95% prediction interval 
of AUCs based on the simulation with the population pharmacokinetic model lies within the AUC 
range of 55-162 µg.hr/mL for the mid-point of each weight band, the dose strengths to be 
administered for the lower weight band subjects i.e. for infants 6 months to 2 years will be as listed 
in the protocol. Further original serial (but sparse) sampling may be limited to the subjects 6 
months to 2 years.  
If it is found that due to insufficient number of children being enrolled in the lowest weight band(s) 
the prediction intervals are wider in that lowest weight band, then further serial (but sparse) 
sampling may be limited to the children being enrolled in the lowest weight band. The analyses will 
then be repeated after next set of 4 subjects with serial  PK sampling and so on until the TQ PK for 
that weight band are adequately characterized and the 95%  interval within the targeted 55-162 
µg.hr/mL. Additionally, based on the available data post the two planned interim analyses, up to 
two samples will be collected in all children enrolled to provide data for the final population PK 
analysis of TQ to be conducted at the end of the study.
The second interim analysis will take place only if serial but sparse PK sampling is continued after 
the first interim analysis. At the end of any interim analysis, if the data and the M&S outcome 
reliably confirm the previously predicted TQ doses across various pediatric weight bands, or allow 
reliable estimation of TQ PK in the pediatric population, the PK sampling scheme in the subjects to 
be enrolled next may be modified or reduced as deemed appropriate.  
At the end of any interim analysis, in the unlikely event of the data and the M&S outcome 
suggesting that the previously predicted TQ doses across various pediatric weight bands are 
grossly incorrect e.g. >2-3 fold off targeted exposure, existing pediatric PK data may be utilized to 
estimate a new dosing regimen. Exposure will be confirmed by continuing the sparse but serial PK 
sampling in the next set of 16 subjects with the new dosing scheme as deemed appropriate and 
necessary. One way to achieve this will be to modify the weight bands and TQ doses across the 
weight bands based on dose strengths. If the M&S outcome suggests that the previously predicted 
TQ doses across various pediatric weight bands are slightly off targeted exposure (e.g. <1.5 fold), 
the dosing may be continued as is, unless there are any safety concerns based on emerging data.

After study completion, the Final POP PK analysis will be performed to determine an appropriate 
dosing regimen across various weight bands in this population.
Any deviations from the analysis plan will be described in detail in the study report.
10.13.4.3.
Final TQ POP PK Analysis
Upon completion of the study, final POP PK analysis will be undertaken. All PK evaluable data will 
be utilized for this analysis to confirm the dose regimen in the pediatric population across various 
weight bands. If the interim analysis demonstrate that the TQ PK was slightly different than 
previously predicted, M&S with the full dataset will be conducted to define the new dosage regimen 
across weight bands to ensure that the systemic TQ exposure across various weight bands in 
pediatric population is comparable to that in adult population. The simplest approach will be to 
modify the previously defined weight bands and the doses across these weight bands. The dosing 
scheme will be recommended in the study report. 
Analysis of the TQ PK data from the pediatric study may also guide formulation of different dose 
strengths i.e. having fewer, more or different dose strengths than those used in the current 
pediatric study to support the TQ pediatric indication post approval. M&S will be undertaken to 
recommend the dose regimen with any new dose strengths across various pediatric population 
weight bands that provides exposure similar to that in adult population with the 300 mg TQ dose.
Any deviations from the analysis plan will be described in detail in the study report.
