NCT04708496

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.

Outcome Measures

Primary Outcomes (1)

  • 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.

    Day 42

Secondary Outcomes (9)

  • Change Maximum concentration [Cmax] of the antimalarials (Artemether, dihydroartemisinin [DHA], lumefantrin and desbutylumefantrine

    over 120hours

  • Measuring level of Hemoglobin

    Hemoglobin will be measured from on follow-up days; 7, 14, 21 and 28.

  • Change in Area under the time-concentration curve [AUC] of the antimalarials (Artemether, dihydroartemisinin [DHA], lumefantrin and desbutylumefantrine

    over 120hours

  • Change in Time to maximum concentration [Tmax] of the antimalarials (Artemether, dihydroartemisinin [DHA], lumefantrin and desbutylumefantrine)

    over 120hours

  • Change in Clearance [Cl/F] of the antimalarials (Artemether, dihydroartemisinin [DHA], lumefantrin and desbutylumefantrine)

    over 120hours

  • +4 more secondary outcomes

Study Arms (3)

Standard dose of Artemether lumefantrine

EXPERIMENTAL

Dose comparison-concurrent control In this arm, Participants receiving Efavirenz400mg based ART will be randomized to standard dose Artemether Lumefantrine when treating uncomplicated malaria in HIV-malaria co-infected participants

Drug: Artemether-lumefantrine

Double dose Artemether lumefantrine

EXPERIMENTAL

Dose comparison concurrent control In this arm, Participants receiving Efavirenz based ART will be randomized to double dose Artemether Lumefantrine when treating uncomplicated malaria in HIV-malaria co-infected participants

Drug: Artemether-lumefantrine

5 day course of Artemether lumefantrine

EXPERIMENTAL

Dose comparison concurrent control In this arm, Participants receiving Efavirenz based ART will be randomized to 5 day course of Artemether Lumefantrine as opposed to the standard 3day course when treating uncomplicated malaria in HIV-malaria co-infected participants

Drug: Artemether-lumefantrine

Interventions

A three-arm single blind Randomized Clinical Trial in which HIV-malaria co-infected individuals with uncomplicated malaria receiving efavirenz-based ART will be randomized to one of three arms; a standard dose of artemether-lumefantrine, or a double dose of artemether-lumefantrine, or a 5-day course of artemether-lumefantrine for treatment of uncomplicated malaria. Participants will be followed up for 42 days to determine safety, drug pharmacokinetics and malaria treatment outcomes. The 4th objective focuses on the interaction between Dolutegravir and Artemether Lumefantrine hence this will be a single blind pharmacokinetic trial among HIV-malaria co-infected individuals receiving Dolutegravir based ART and standard dose of artemether-lumefantrine for treatment of uncomplicated malaria.
