Congenital malaria is an extremely rare condition which occurs due to transplacental transmission of maternal infection.Clinical features include fever, irritability, feeding problems, anemia, hepatosplenomegaly and jaundice. Clinical features commence only after three weeks due to the protective effect of transplacentally transmitted antibodies. References

The study included a single dose as well as a combination of 3 daily doses (ranging from 0.2 to 20 micrograms/kg) given consecutively. It was determined that single doses did not result in noteworthy production of epithelial cells. Study 970136 (Randomized, double-blind, placebo-controlled, dose-escalation). Intended to determine the safety and tolerability, and pharmacokinetics of a single dose, administered intravenously (ranging from 5–20 micrograms/kg) in 24 healthy volunteers. It was found that systematic exposure was proportional to the administered dose. Extravascular distribution of the drug was noted. Study 970290 (Open-label). Intended to evaluate pharmacokinetic properties intersubject variability of the drug in four, healthy male volunteers. It was determined that a high intersubject variability was not the cause of dosing errors in previous studies. Study 970276 (Dose-escalation). Intended to determine the safety and tolerability, pharmacokinetic and pharmacodynamics properties of the drug versus a placebo in 18 healthy volunteers. The study consisted of daily IV doses in three consecutive days (20 or 40 micrograms/kg). It was determined that subjects that received three daily doses of 40 micrograms/kg demonstrated adequate production of epithelial cells in the buccal mucosa. Predicted elevation in amylase and lipase were also determined. Study 20010192 (Randomized, double-blind, placebo-controlled, dose-escalation). Intended to determine safety and tolerability, pharmacokinetic and pharmacodynamics properties of the drug versus a placebo by utilization of a single IV dose (ranging from 60 to 250 micrograms/kg) in 84 healthy volunteers.
