Outcomes

Primary Outcome Measures

Measure of malaria treatment outcome adjusted by genotyping and classified as reinfection or recrudescence.
The Primary outcome measure will be the malaria treatment outcome adjusted by genotyping and classified as reinfection or recrudescence. Treatment outcomes will be classified on the basis of an assessment of the parasitological and clinical outcomes of antimalarial treatment according to the latest WHO guidelines. Thus, all patients will be classified as having early treatment failure, late clinical failure, late parasitological failure or an adequate clinical and parasitological response. Clinical Treatment outcomes will be assessed according to WHO criteria as; early treatment failure and late treatment failure. Parasitological treatment outcomes will be classified as late parasitological failure and adequate clinical and parasitological response.

Secondary Outcome Measures

Change Maximum concentration [Cmax] of the antimalarials (Artemether, dihydroartemisinin [DHA], lumefantrin and desbutylumefantrine
Plots of plasma concentration versus time curves will be produced for artemether, dihydroartemisinin, lumefantrine and desbutyl-lumefantrine. Pharmacokinetic parameter Cmax derived directly from the data. The Cmax pharmacokinetic parameter will be presented using descriptive summary statistics including geometric means, geometric mean ratios (GMR) and confidence intervals (CI), or medians and interquartile ranges. The CIs will be determined using logarithms of the individual geometric mean values; the calculated values will be then expressed as linear values.
Measuring level of Hemoglobin
Anemia is a common with Malaria. The hemoglobin levels will be measured to assess for any reduction and also recovery of the hemoglobin level following treatment.
Change in Area under the time-concentration curve [AUC] of the antimalarials (Artemether, dihydroartemisinin [DHA], lumefantrin and desbutylumefantrine
Plots of plasma concentration versus time curves will be produced for artemether. AUC over 24 hours (AUC0-24) will be calculated using non-compartmental methods (WinNonlin® Version 6.2, Pharsight). The pharmacokinetic parameter will be presented using descriptive summary statistics including geometric means, geometric mean ratios (GMR) and confidence intervals (CI), or medians and interquartile ranges. The CIs will be determined using logarithms of the individual geometric mean values; the calculated values will be then expressed as linear values.
Change in Time to maximum concentration [Tmax] of the antimalarials (Artemether, dihydroartemisinin [DHA], lumefantrin and desbutylumefantrine)
Plots of plasma concentration versus time curves will be produced for artemether, dihydroartemisinin, lumefantrine and desbutyl-lumefantrine. Pharmacokinetic parameter time to maximal concentration (Tmax) will be derived directly from the data. The pharmacokinetic parameter will be presented using descriptive summary statistics including geometric means, geometric mean ratios (GMR) and confidence intervals (CI), or medians and interquartile ranges. The CIs will be determined using logarithms of the individual geometric mean values; the calculated values will be then expressed as linear values.
Change in Clearance [Cl/F] of the antimalarials (Artemether, dihydroartemisinin [DHA], lumefantrin and desbutylumefantrine)
Plots of plasma concentration versus time curves will be produced for artemether, dihydroartemisinin, lumefantrine and desbutyl-lumefantrine. The apparent oral clearance will be calculated using non-compartmental methods (WinNonlin® Version 6.2, Pharsight). This pharmacokinetic parameter will be presented using descriptive summary statistics including geometric means, geometric mean ratios (GMR) and confidence intervals (CI), or medians and interquartile ranges. The CIs will be determined using logarithms of the individual geometric mean values; the calculated values will be then expressed as linear values.

The change in trough concentration will be presented using descriptive summary statistics including geometric means, geometric mean ratios (GMR) and confidence intervals (CI), or medians and interquartile ranges. The CIs will be determined using logarithms of the individual geometric mean values; the calculated values will be then expressed as linear values.
Prolongation of the QT interval

5. Study Description

Brief Summary
Optimal is a Randomized clinical trial to optimize treatment of malaria in HIV -malaria co infected patients. It has been demonstrated that, when the antimalarial drug Artemether Lumefantrine is co administered with Efavirenz based ART in HIV-malaria co-infected individuals, sub therapeutic levels of the drug are achieved hence resulting in poor malaria treatment outcomes. The study then hypothesizes that, : HIV-malaria co-infected individuals receiving efavirenz-based ART plus a double-dose or 5-day course of artemether-lumefantrine will achieve higher and adequate artemether-lumefantrine serum concentrations with adequate 42-day treatment outcomes compared to individuals with HIV-malaria co-infection receiving efavirenz-based ART plus a standard-dose of artemether-lumefantrine.
Detailed Description
Malaria and HIV have significant interactions at various levels. The geographical and epidemiological overlap increases risk for co-infection and co-treatment. The immune suppression due to HIV increases malaria incidence, severity and risk for poor treatment outcomes including mortality and adverse pregnancy outcomes such as anemia and low birth weight. Malaria infection increases HIV viral replication. Both malaria and HIV are treated with combination therapy to enhance treatment outcomes and reduce risk for development of resistance, consequently creating potential for drug-drug interactions (DDIs) when the two diseases are treated concomitantly. Previous studies demonstrated significant reduction in systemic exposure to Artemether, its metabolite dihydroartemisinin, and the long acting partner drug lumefantrine when the ACT artemether-lumefantrine was co-administered with efavirenz-based ART to HIV-malaria co-infected individuals. Exposure to sub therapeutic antimalarial drug concentrations poses a risk for poor malaria treatment outcomes such as prolonged morbidity, anemia, death and poor birth outcomes for pregnant women plus increased economic costs and risk for drug resistance. There are currently limited drug options available for both malaria and HIV treatment especially in sub-Saharan Africa, thus the need to protect drug effectiveness. There are very scanty data on effects of drug interactions on malaria clinical outcomes, and such studies would be unethical currently. Despite these gaps, co-administration of antimalarial and antiretroviral drugs occurs with no guidance on therapeutic interventions to overcome these deleterious effects. Data are therefore urgently needed to optimize treatment of malaria for HIV-malaria co-infected individuals. General Objective: To utilize innovative interventions to overcome drug interactions between artemether-lumefantrine and efavirenz to guide malaria treatment for individuals co-infected with HIV and malaria. Specific objectives: Objectives To determine the safety and Pharmacokinetics of the double dose artemether-lumefantrine when administered to healthy volunteers (malaria negative and HIV negative individuals). To determine the safety and Pharmacokinetics of the 5-day course of artemether-lumefantrine when administered to healthy volunteers (malaria negative and HIV negative individuals). To determine the safety, pharmacokinetics and malaria treatment outcome of a standard dose of artemether-lumefantrine compared to double of the standard dose for weight and a 5-day course of artemether-lumefantrine for treatment of uncomplicated malaria among HIV-Malaria co-infected individuals receiving efavirenz (400mg) based ART. To determine the safety and Pharmacokinetics of artemether-lumefantrine when administered with Dolutegravir based ART among HIV-malaria co-infected individuals.
