Safety and immunogenicity of a three-component blood-stage malaria vaccine in adults living in an endemic area of Papua New Guinea.

A Phase I safety and immunogenicity study with a three-component blood-stage malaria vaccine was conducted in adult male subjects living in an endemic area of Papua New Guinea. The preparations were recombinant proteins which corresponded to parts of the two merozoite surface proteins of Plasmodium falciparum (MSP1 and 2), and of the ring-infected erythrocyte surface antigen (RESA). The three proteins were emulsified with the adjuvant Montanide ISA720.

Mefloquine in the Prophylaxis of P. Falciparum Malaria.

Background: The objectives of this study were (1) to compare the efficacy of Lariam (mefloquine) with that of Fansimef (mefloquine, sulfadoxine, and pyrimethamine), Fansidar (sulfadoxine and pyrimethamine), chloroquine, and placebo in suppressing asexual parasitemia in semi-immune persons living in an area endemic for Plasmodium falciparum malaria; and (2) to compare the tolerance of these drugs when taken over a prolonged period of time. Method: A randomized double-blind comparative placebo-controlled study was undertaken in the village of Biasso, 60 km from Abidjan in the southern part of the Ivory Coast, a region where P. falciparum malaria is endemic.

Mefloquine prophylaxis: an overview of spontaneous reports of severe psychiatric reactions and convulsions.

Since the time of its introduction in 1985, mefloquine (Lariam) has been used extensively for malaria prophylaxis. The international Drug Safety Department of the manufacturer gathered all spontaneous adverse drug reactions reported in association with this drug from all available sources and monitored the literature on a world-wide basis. The serious neurologic and psychiatric adverse events reported in association with Lariam prophylaxis from the time of introduction until May 1991 were reviewed.
