Artemisia Annua Infusion for the Treatment of Asymptomatic Plasmodium Falciparum Infection (ART-CT001)
Clinical Assessment of the Safety and Efficacy of Artemisia Annua Infusion Preparation for the Treatment of Asymptomatic Plasmodium Falciparum Infection in Semi-immune Adults in Gabon
The goal of this clinical trial is to determine whether Artemisia annua dried leaves, used as an infusion, can treat individuals with malaria parasites but no symptoms. The main question it aims to answer is:
Can Artemisia annua infusion be used to treat malaria?
Researchers will compare those receiving Artemisia annua infusion with those receiving an infusion of Centaurii herba (which has no effect on malaria parasites) to see whether all individuals treated with Artemisia annua infusion are cured, which should not be the case for those receiving Centaurii herba infusion.
Participants will
- drink Artemisia annua infusion over seven days (three days at our research centre and four days at their home
- visit the research centre once a week for three weeks after treatment for one month for safety reasons

Description détaillée
For safety reasons, participants will be followed up daily for malaria-like symptoms and parasite counts until the end of treatment. Indeed, if they are not free of parasites after seven days of treatment, they will receive rescue treatment, which is the WHO-recommended malaria treatment.
Similarly, if the number of parasites in their blood increases or they develop malaria-like symptoms during treatment, they will receive rescue treatment.

Dried Artemisia annua leaves will be used to prepare an infusion by adding 5 mg of dried leaves to 1 litre of boiled water.
The mixture will be left to stand for 15 minutes, then stirred and strained before being administered to the participant.
Participants will receive 1 litre of this infusion (prepared each morning) per day for seven consecutive days.
The research team will administer the daily dose in three splits at 8-hour intervals.
