¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Percentage of Participants With Parasite Clearance at Day 28
Periodo de tiempo: Day 28
Parasite clearance was defined as the clearance of asexual Plasmodium falciparum (P falciparum) parasitemia (defined as three consecutive 0 parasite counts) within 7 days of initiation of treatment, without subsequent recrudescence up to Day 28. Failure to achieve clearance of asexual P falciparum parasitemia was defined as parasitemia not cleared within 7 days of initiation of treatment, or subsequent recrudescence (confirmed by molecular testing) by Day 28 after achieving clearance. Percentage of participants with clearance is reported. Here "N" (Number of participants analyzed) signify participants who were evaluable (parasitological per protocol) at Day 28.
Day 28

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Percentage of Participants With Early Treatment Failures (ETF)
Periodo de tiempo: Baseline up to Day 28
ETF was defined as a participant meeting any of these criteria: development of signs of severe malaria (impaired consciousness [for example, obtundation, unarousable coma, delirium, stupor], respiratory distress [respiratory rate greater than or equal to {>=} 30 breaths/minute], seizures, hypoglycemia [glucose less than or equal to {<=} 40 milligram/deciliter], gross hematuria, increase in parasitemia to greater than 100,000 parasites/microliter in 48 hours or later after the first treatment dose was administered) any day from Day 0 to 3 in the presence of P falciparum parasitemia; parasite count on Day 2 > Day 0 (baseline), irrespective of axillary or oral temperature; parasite count on Day 3 > 37.5 degrees Celsius (axillary temperature) and >38 degrees Celsius (oral temperature) and parasite count on Day 3 >=25 percent (%) of the first available parasite density on Day 0 (baseline).
Baseline up to Day 28
Percentage of Participants With Late Treatment Failures (LTF)
Periodo de tiempo: Baseline up to Day 28
LTF included late clinical failure (LCF) and late parasitologic failure (LPF). LCF is defined as a participant meeting any of these criteria: development of signs or symptoms of severe malaria after Day 3 in the presence of P falciparum parasitemia, without previously meeting any of the criteria of ETF or presence of P falciparum parasitemia and fever or history of fever on any day from Day 4 to Day 28, without previously meeting any of the criteria of ETF. LPF is defined as presence of P falciparum parasitemia on any day from Day 7 to Day 28 and the absence of fever or history of fever without previously meeting any of the criteria of ETF or LCF.
Baseline up to Day 28
Percentage of Participants With Resistance to Treatment
Periodo de tiempo: Days 7, 14, 21, 28, 35, 42
Resistance is measured by clearance of asexual P falciparum parasitemia and categorized into 3 levels; resistance I (RI): clearance of asexual P. falciparum parasitemia before Day 7 followed by recurrence on or after Day 7, resistance II (RII): marked reduction (<=25% of baseline) of asexual P. falciparum parasitemia but no clearance prior to and up to Day 7, and resistance III (RIII): no marked reduction (>25% of baseline) of asexual P. falciparum parasitemia. Recurrence was defined as the reappearance of asexual P. falciparum parasitemia following a quiescent or latent period after the cessation of the primary attack. Percentage of participants with resistance as measured by RI, RII and RIII is reported.
Days 7, 14, 21, 28, 35, 42
Percentage of Participants With Clinical Cure
Periodo de tiempo: Day 3, 7, 28, and 42
Clinical Cure is defined as resolution of the participant's fever and other symptoms attributed to P falciparum malaria (for example, abdominal pain, malaise, and headache).
Day 3, 7, 28, and 42
Percentage of Participants With Parasite Clearance at Day 7, 14, 21, 35, 42
Periodo de tiempo: Day 7, 14, 21, 35, 42
Parasite clearance was defined as the clearance of asexual Plasmodium falciparum (P falciparum) parasitemia (defined as three consecutive 0 parasite counts) within 7 days of initiation of treatment, without subsequent recrudescence up to Day 28. Failure to achieve clearance of asexual P falciparum parasitemia was defined as parasitemia not cleared within 7 days of initiation of treatment, or subsequent recrudescence (confirmed by molecular testing) by Day 28 after achieving clearance. Percentage of participants with clearance is reported. Here "N" (Number of participants analyzed) signify participants who were evaluable (parasitological per protocol) at Day 28.
Day 7, 14, 21, 35, 42
Percentage of Participants With Gametocyte Clearance
Periodo de tiempo: Day 7, 14, 21, 28, 35, 42
Gametocyte clearance was defined as clearance of P falciparum gametocytemia (defined as attainment of 3 consecutive 0 gametocyte counts) without subsequent recurrence through the day of consideration. Recurrence was defined as the reappearance of asexual P. falciparum gametocytemia after achieving clearance. Percentage of participants with gametocyte clearance were reported.
Day 7, 14, 21, 28, 35, 42
Fever Clearance Time
Periodo de tiempo: Baseline up to Day 42
Fever clearance time (FCT) was defined as the time from baseline to the first of 2 consecutive time points with temperature less than (<) 37.5 degree Celsius (C) (axillary temperature) or <38 degree C (oral temperature).
Baseline up to Day 42
Parasite Clearance Time
Periodo de tiempo: Baseline up to Day 42
Asexual P falciparum parasite clearance time was defined as the time from baseline to the first of the 3 consecutive 0 parasite counts.
Baseline up to Day 42
