Phase I bioavailability studies completed
The phase I bioavailability studies in healthy adult volunteers were performed in South Africa with the aim to determine the pharmacokinetic properties of the Racemate (Rac)-PZQ and L-PZQ formulation candidates in comparison to the current 600 mg PZQ commercial racemate tablet formulation (Cesol). Both formulation candidates showed a good safety profile and acceptable palatability.

Expert Meeting 1: Target Product Profile
Soon after its formation, the Consortium collaborated with a panel of experts in schistosomiasis and pediatric formulations, at a meeting in Geneva in August 2012. The goal was to develop a target product profile (TPP) delineating both required and desirable formulation features. Factors taken into account included therapeutic indications, pediatric age group, dosage form, frequency of administration, formulation storage conditions and more.
