Title: Phase IIIb/IV Cohort Event Monitoring Study To Evaluate, In Real Life Setting, The Safety And Tolerability In Malaria Patients Of The Fixed-Dose Artemisinin-Based Combination Therapy Pyramax®
Brief Summary: The study is to be performed in public health facilities in Central and West Africa where Pyramax will be used as treatment of uncomplicated malaria episodes, including repeat episodes. The study is to assess the safety of Pyramax, particularly in patients with underlying liver function abnormalities, in patients who have co-morbid conditions, such as HIV, and also in very small children (\<1 year of age).

* Living in the catchment area of the study (within a radius of \~10 km from St. Jude's Clinic, Mbita, Kenya);
* Having microscopically confirmed P. falciparum mono-infection (asexual parasite density 1,000-200,000 µL-1).

Exclusion Criteria:

* Signs and symptoms of severe malaria (according to WHO criteria for severe malaria, (WHO 2012)) or any other severe illness necessitating parenteral treatment;
* Mixed Plasmodium infection;
* Clinically suspected (oedema, jaundice and/or ascites) or reported hepatic and/or renal impairment (any cause, as reported by parents/guardians and/or evident from medical history);
* Having anaemia with an Hb \<6 g/dL;
* Evidence of severe malnutrition (severe wasting: z-score weight for age \<-3 and severe stunting: z-score height for age \<-3 (WHO 2009b));
* Having received anti-malarial therapy in the previous two weeks;
* Known history of hypersensitivity, allergic or adverse reactions to artesunate, artemether-lumefantrine or other artemisinins;
* Participating in other anti-malarial drug intervention studies;

B: Inclusion Criteria:

1. Male or female patients between the age of 15 and 60 years of age inclusive
2. Written informed consent, in accordance with local practice, provided by patient and/or parent/guardian/spouse. If the patient is unable to write, witnessed consent is permitted according to local ethical considerations

4. Weight of between 35 kg and 75 kg inclusive
5. Presence of acute symptomatic uncomplicated P. falciparum malaria with a diagnosis confirmed by a positive blood smear with asexual forms of P. falciparum only (i.e. no mixed infection) plus history of fever within the previous 24 hours or a measured temperature of ≥37.5°C (depending on method of measurement):

   * the acceptable range is between 1,000 and 100,000 asexual parasite count/μl of blood and
   * axillary/tympanic temperature of ≥ 37.5°C or oral/rectal temperature of ≥ 38.0°C
6. Ability to swallow oral medication
7. Ability to comply with study visit schedule: patients will be hospitalised for at least 4 days and will be required to remain in the vicinity of the trial site for a minimum of 7 days or until clearance of fever and parasite for at least 24 hours, whichever is the later. The patient is to return to the study site or to make themselves available for all scheduled follow up visits, until discharge at Day 42.
8. Females must not be pregnant or lactating and be willing to take measures to not become pregnant during the study period

Known history or evidence of clinically significant disorders such as cardiovascular (including arrhythmia), respiratory (including active tuberculosis), hepatic, renal, gastrointestinal, immunological (including active HIV-AIDS), neurological (including auditory), endocrine, infectious, malignancy, psychiatric or other clinically important abnormality (including head trauma).
5. Presence of febrile conditions caused by diseases other than malaria
6. Known history of hypersensitivity, allergic or adverse reactions to pyronaridine or artesunate or other artemisinins
7. Evidence of use of any other antimalarial agent within 2 weeks prior to the start of the study confirmed by a negative urine test or using Eggelte dipsticks
