The purpose of this protocol is to perform Phase 1 (safety/toxicity and pharmacokinetic) Studies of an investigational aminoquinoline antimalarial (AQ-13) in human subjects. The compound to be studied (AQ-13) is being examined because it is active in vitro against Plasmodium falciparum malaria parasites resistant to chloroquine (CQ) and other antimalarials (multi-resistant P. falciparum), and because its safety was similar to that of CQ in preclinical studies performed by SRI International (IND 55,670). AQ-13 was also selected for study because it is active in vivo in two monkey models of human malaria: 1] P. cynomolgi in the rhesus monkey (Macaca mulatta), a model of human infection with P. vivax, and 2] CQ-resistant P. falciparum in the squirrel monkey, a model of human infection with CQ-resistant P. falciparum.
