| Primary | Percentage of Participants With Clinically Relevant Hemolysis. | Up to Day 180 | Clinically relevant hemolysis is defined as a decrease in hemoglobin of \>=30% or \>3 grams per deciliter (g/dL) from Baseline; or, an overall drop in hemoglobin below 6.0 g/dL at any visit after the first dose of study medication. The percentage of participants with clinically relevant hemolysis has been summarized. Safety Population comprised of all randomized participants who received at least one dose of blinded study medication. |
| Primary | Percentage of Female Participants With Moderate Glucose-6 Phosphate Dehydrogenase (G6PD) Deficiency Experiencing Clinically Relevant Hemolysis. | Up to Day 180 | Clinically relevant hemolysis is defined as a decrease in hemoglobin of \>=30% or \>3 g/dL from Baseline; or, an overall drop in hemoglobin below 6.0 g/dL at any visit after the first dose of study medication. Despite additional efforts, no females with moderate G6PD-deficiency were enrolled that experienced clinically-significant hemolysis during the study; hence, the end point could not be estimated. |
| Secondary | Rate of Relapse-free Efficacy at Six Months Post Dose | 6 months post dose | A participant was considered to have demonstrated relapse-free efficacy at 6 months if: a) Participant had non-zero P. vivax asexual parasite count at Baseline. b) Participant showed initial clearance of P. vivax parasitemia defined as two negative asexual P. vivax parasite counts, with at least 6 hours between the counts, and no positive counts in the interval. c) Participant had no positive asexual P. vivax parasite count at any assessment prior to or on Study Day 201 following initial parasite clearance. d) Participant did not take a concomitant medication with anti-malarial activity at any point between Study Day 1 and their last parasite assessment. e) Participant is parasite-free at 6 months.

Fever clearance was considered to have been achieved once an initial temperature of more than 37.4 degree Celsius is reduced to a value less than or equal to 37.4 degree Celsius, in the absence of value more than 37.4 degree Celsius in the following 48 hours up to the Day 8 visit. The time taken to achieve fever clearance was analyzed by Kaplan-Meier method. |
| Secondary | Time to Gametocyte Clearance | Up to Day 180 | Gametocyte clearance time is defined as time from first dose until the first slide that was gametocyte negative and remained so at the next slide reading. The time taken to achieve gametocyte clearance was analyzed by Kaplan-Meier method. |
| Secondary | Number of Participants With Recrudescence | Up to Day 32 | Recrudescence is defined as any P. vivax parasitemia occurring on or before Day 32 (that is, blood stage treatment failure). A participant was considered to have had a recrudescence if both of the following were true: a) Participant had a positive P. vivax asexual parasite count at Baseline and demonstrated clearance (that is, did not have two negative asexual P. vivax parasite counts, with at least 6 hours between the counts, and no positive counts in the interval). b) Participant had a positive genetically homologous asexual P. vivax parasite count, after their zero count in Days 1 to 5, but on or before Study Day 32. The number of participants with recrudescence before Study Day 33 has been presented. |
| Secondary | Number of Participants With Genetically Homologous and Genetically Heterologous P. Vivax Infections | Up to Day 180 | Two drops of peripheral blood were collected onto pre-printed filter paper for subsequent deoxyribonucleic acid (DNA) extraction and polymerase chain reaction (PCR) analysis of Plasmodium species on all participants at screening (Day 1; pre-dose) and; if necessary, at the time of the first recrudescence/relapse or re-infection. PCR of the P. vivax genes, was used to distinguish between genetically homologous and genetically heterologous infection. The number of participants with genetically homologous and genetically heterologous P. vivax infections has been summarized for each treatment group. Only those participants with an infection occuring on or after Study Day 33 were analyzed. |

The number of participants with clinical chemistry laboratory values outside the extended normal range (F3) has been presented. The upper and lower limits for F3 range were defined by multiplying the normal range limits by different factors. High and low indicated that the participants had values flagged as high and low respectively for the particular parameter any time on-treatment. Safety Population consisted of all randomized participants who received at least one dose of blinded study medication. |
