Study type
Interventional
Description of intervention(s) / exposure
To assess the therapeutic efficacy of pyronaridine-artesunate (Pyramax®) tablets 180mg/60mg
a) the dose administered:
Body weight (kg) Daily dose (mg) Number of tablets
PYR AS
20 - < 24 180 60 1
24 - < 45 360 120 2
45 - < 65 540 180 3
> 65 720 240 4

b) the duration of administration : 3 days.
c) Pyronaridine- artesunate will be taken orally with water, once daily for 3 days. Each dose will be administered under supervision in the clinic or if not possible by a home visitor to the patient’s home. A dose will be repeated in full if vomiting occurs within 30 minutes of administration of the first day of administration only. This event will be documented in the case record form (CRF).

Timepoint [4] 350002 0

Secondary outcome [5] 350003 0
• Documented AEs and SAEs and relationships to study drugs.
Patients will be screened for common adverse events using and will be recorded in a predefined list of events, with in addition an open text field for non-listed events. Changes in liver enzymes will be recorded.. Clinical signs typical of an acute malaria episode will not be considered Adverse Events unless the healthcare personnel considers these events as exceptional due to their evolution, their seriousness, or another factor related to these events.
Liver function test results that are codified as adverse events, and/or elevations that occur rapidly or exceed multiples of the upper limits of normal, merit further inquiry on the part of the investigator. The laboratory tests that are relevant in this regard include:
a. ALT (SGPT), AST (SGOT), Examples of elevations that may require more intensive inquiry on the part of the investigator include an ALT value that exceeds 5.0 times the upper limit of normal.
b. Total bilirubin value that exceeds 2 times the upper limit of normal (Hy’s law). With massive hepatic injury, the ability of the liver to excrete conjugated (or direct) bilirubin diminishes.
c. Therefore, the presence of ALT >3xULN and concomitant bilirubin >2xULN (>35% direct), suggests significant liver injury, mandating the need for specialist consultation, and follow up of liver chemistries twice weekly until values normalise or substantively improve.
Timepoint [5] 350003 0
Assess 42 days afer doses.
Liver function tes (ALT, ÁST and bilirubin) assessed at D0, D7 and D28..

Statistical methods / analysis
The primary analysis will be on an ‘intention to treat’ basis, including all patients enrolled into the study. Primary outcome will be the Kaplan Meier analysis up to day 42 of follow-up. A per protocol analysis will be based on all enrolled patients complying with all inclusion criteria who received a full course of the study drugs. Secondary analyses will include the ‘adequate parasitological and clinical response’ (APCR) at day 42. Safety and tolerability measurements will be summarized for the ITT patient population.
