Summary of Clinical Use
Clinical evaluation of ganaplacide indicates promising activity against uncomplicated P. vivax or P. falciparum infections in adult malaria patients (results from Phase 2b trial NCT01753323 published in [4]). Recruitment has commenced for a Phase 2 trial for combination therapy with lumefantrine (NCT03167242, last update January, 2020).
Mechanism Of Action and Pharmacodynamic Effects
Decreased susceptibility to ganaplacide is associated with mutations in three P. falciparum genes, PfCARL (cyclic amine resistance locus), PfUGT (UDP-galactose) and PfACT (Acetyl-CoA transporter) but it is thought that these are involved in broad mechanisms of antimalarial drug resistance and are not considered to be likely targets of the imidazolopiperazines [2-3].
