研究概览
简要总结
This is an initial efficacy study of a candidate antimalarial in human subjects with uncomplicated malaria caused by the most common and most important parasite in Africa (Plasmodium falciparum). This study will enroll 66 adult Malian males with uncomplicated P. falciparum malaria and randomize them to treatment with 1750 mg of the investigational drug (AQ-13) by mouth over 3 days or the current standard treatment, which is 2 doses of Coartem twice daily for 3 days. The hypothesis underlying this study is that AQ-13 will be similarly effective to Coartem for the treatment of uncomplicated P. falciparum malaria due to both chloroquine-susceptible and chloroquine-resistant parasites.

详细描述
This is an initial efficacy study (Phase 2 Proof of Concept Study) of a candidate antimalarial in human subjects with uncomplicated malaria caused by the most common and most important parasite in Africa (Plasmodium falciparum). This study will enroll 66 adult Malian males with uncomplicated P. falciparum malaria and randomize them to treatment with 1750 mg of the investigational drug (AQ-13) by mouth over 3 days or the current standard treatment, which is 80 mg of artemether and 480 mg of lumefantrine twice daily for 3 days. The hypothesis underlying this study is that AQ-13 will be similarly effective to Coartem for the treatment of uncomplicated P. falciparum malaria due to both chloroquine-susceptible and chloroquine-resistant parasites.

研究组 & 干预措施
AQ-13
Adult Malian males 18 years of age or older with uncomplicated P. falciparum malaria who agree to participate and provide their informed consent will be randomized to receive treatment with either AQ-13 or Coartem. Intervention 'AQ-13 Treatment' Participants randomized to the AQ-13 arm will be treated with two (350 mg) capsules on days 1 and 2 and one (350 mg) AQ-13 capsule on day 3 for a total oral dose of 1750 mg of AQ-13 (5 capsules containing 350 mg apiece) over 3 days.
干预措施: AQ-13 Treatment (Drug)
Coartem Treatment
Adult Malian males 18 years of age or older with uncomplicated P. falciparum malaria who agree to participate and provide their informed consent will be randomized to receive treatment with either AQ-13 or Coartem. Intervention: Active Comparator: Coartem. Participants randomized to the Coartem arm will be treated with 80 mg artemether and 480 mg lumefantrine at the time of diagnosis and 8 hours later on day 1, the same doses (80 mg artemether and 480 mg lumefantrine) twice on day 2 (24 and 36 hours after diagnosis) and twice more on day 3 (48 and 60 hours after diagnosis) for total oral doses of 480 mg artemether and 2880 mg lumefantrine over 3 days.
干预措施: Coartem Treatment (Drug)
结局指标
主要结局
Cure Rates of AQ-13 and Coartem for Uncomplicated Plasmodium Falciparum Malaria in Adult Malian Males.
时间窗: Subjects are followed for 42 days after beginning treatment with either AQ-13 or Coartem..
Cure rate is defined as a lack of recrudescence within 42 days PCR-corrected (correcting for new infections due to treatment failures). The investigators were looking for no evidence of recurrent infection with the same parasite genotype after reduction of the asexual parasitemia to less than 25% of the admission value by day 3 and clearance of asexual parasites and fever by day 7 to measure the cure rate. Failure is defined as lack of cure.
次要结局

- Peak Cmax(42 Days)
- Number of Participants With Recrudescence of Infection(Within 42 days after beginning treatment with either AQ-13 or Coartem)
- QTc Interval Response Following Antimalarial Treatment(Between dosing and 4 hours after dosing)
- Mean Residence Time(42 Days)
- Parasite Clearance Time(From the time of beginning treatment with either AQ-13 or Coartem to the first of 2 successive negative blood smears, assessed during the 1 week inpatient stay.)
- 1-week AUC(42 days)
- Mean Fever Clearance Time in Days(Days 1-7 after beginning treatment with either AQ-13 or Coartem)
- Clearance(42 Days)
- Time to Peak Tmax(42 days)
- Elimination t½(42 Days)
