Title	Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious TEAEs
Description	An adverse event (AE) is defined as any untoward medical occurrence in a participant under clinical investigation, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Serious adverse event (SAE) is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/ birth defect, other situations such as important medical events and events of possible drug induced liver injury with hyperbilirubinemia. 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). Number of participants with TEAEs and serious TEAEs have been presented.

PQ placebo capsules were administered orally once daily for 14 days starting on the same day as TQ administration.	Participants were administered CQ 600 mg tablet once daily on Days 1 and 2 and CQ 300 mg on Day 3. Participants received a single TQ placebo tablet orally on Day 1 or Day 2.

Title	Number of Participants With Electrocardiogram (ECG) Findings
Description	12 lead ECG was performed with the participant in a semi-supine position having rested in this position for at least 10 minutes. ECG assessments were performed in triplicate at screening followed by single ECGs 12 hours after the first dose of study medication and at Day 29. The number of participants with abnormal-clinically significant ECG findings have been presented. The 12 Hour Post Randomized Treatment (11.5-12.5 Hours) timepoint included all readings taken between 11.5 and 12.5 hours post randomized treatment. The 12 Hour Post Randomized Treatment (8-72 Hours) timepoint is a sensitivity analysis of the 12 Hour post randomized treatment timepoint, including all readings taken between 8 and 72 hours post randomized treatment. Only those participants with data available at the specified data points were analyzed (represented by n=X in category title).

Title	Change From Baseline in Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Mean Arterial Pressure (MAP)
Description	Vital signs were measured twice a day on Days 1 through 3, at least 4 hours apart, and immediately prior to pharmacokinetic (PK) measurements. MAP was calculated as the sum of SBP and two times DBP divided by 3. The mean and standard deviation of SBP, DBP and MAP has been presented. The values presented does not include Day 3 assessments for participant number 570. Baseline value is defined as the latest pre-treatment assessment where treatment is their first dose of study medication (CQ/PQ/TQ/Placebo). Change from Baseline is the value at post dose minus Baseline value. Only those participants with data available at the specified data points were analyzed (represented by n=X in category title).

Assessments were carried out at Day 180 if the Day 90 assessments showed abnormalities. The last assessment performed on the day of randomization or earlier was considered Baseline. Change from Baseline is the value at post dose visit minus the Baseline value. Best corrected visual acuity was assessed individually for each eye. Scores were recorded as a ratio. The values were used to derive a logMAR score for statistical analysis where logMAR=-1x log10 (ratio score). The number of participants with change in Best Corrected Visual Acuity Test Scores from Baseline has been presented where possible change is defined as a change from Baseline >=0.12 to <0.3 and definite change is defined as a change from Baseline >=0.3 logMAR score.

24. Secondary Outcome

Title	Cost Associated With Relapse Episode of P Vivax Malaria
Description	Health outcomes were evaluated based on the total costs spent on treatment, transport, medication and tests. The cost was summarized according to the place at which the participant went to for care (drug shop, trial clinic, other clinic, hospital emergency center, other). The costs associated with a relapse episode of P. vivax malaria has been presented. Participants may be represented in more than one category, so the total number of participants may be less than the number quoted. Only those participants with data available at the specified data points were analyzed (represented by n=X in category title).

Certain Agreements

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.

GSK agreements may vary with individual investigators, but will not prohibit any investigator from publishing. GSK supports the publication of results from all centers of a multi-center trial but requests that reports based on single-site data not precede the primary publication of the entire clinical trial.
