About

The clinical trial is a Phase I monocentric clinical trial with a two-armed crossover design to evaluate the bioavailability of parenteral Pyronaridine and Artesunate.

Pyronaridine and Artesunate are antimalarial agents with a history of clinical use, and Artesunate has been used clinically in combination with other drugs also. The action of Artesunate is a rapid knock down of the parasites, after which, the drug is quickly cleared as it has a short systemic half-life. Pyronaridine is also rapidly effective in the short term but has a long blood half-life thus providing a more sustained schizonticidal effect.

12 study subjects will be included into the clinical trial after having signed the informed consent, being screened and judged to be eligible. 6 of them (group 1) will, on Day 0, be injected intravenously with 4 mg base/kg of Pyronaridine together with 4 mg/kg of Artesunate. The group 2 (the other 6 subjects) will on the same day (Day 0) be injected intramuscularly with the 4 mg base/kg of Pyronaridine together with 4 mg/kg of Artesunate (into separate sites) 8 weeks later group 1 will be injected intramuscularly with the same amount of Pyronaridine and Artesunate as on Day 0. Group 2 will also get the same amount as on Day 0 but this time the injection will be intravenously for group 2.

The primary objective is to assess the safety and tolerability by measuring (a) the proportion of subjects with adverse events (AEs) and serious adverse events (SAEs) throughout the study; (b) the proportion of subjects with solicited AEs 15 days after IMP injection; (c) the proportion of subjects with unsolicited AEs throughout the clinical trial. Further, the pharmacokinetics of both drugs will be determined.
