Serious AE: an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAE: AE with onset after start of treatment or with onset date before the treatment start date but worsening after the treatment start date. TEAEs included both serious and non-serious TEAEs. Treatment-related TEAEs: reasonably related to the study intervention. Number of participants with TEAEs and treatment related TEAEs were reported. |
| Secondary | Number of Participants With Treatment Emergent Adverse Events (TEAEs) by Severity According to Qualitative Toxicity Scale | Baseline up to Day 27 | Severity of TEAEs were graded using Qualitative Toxicity Scale, as follows: Mild: Participant is aware of the event or symptom, but the event or symptom is easily tolerated; Moderate: Participant experiences sufficient discomfort to interfere with or reduce his or her usual level of activity; Severe: Significant impairment of functioning: the participant is unable to carry out his or her usual activities. Number of participants with TEAEs by severity were reported. |
| Secondary | Number of Participants With Clinically Relevant Changes From Baseline in Laboratory Parameters | Baseline up to Day 27 | Laboratory investigation included hematology, biochemistry and urinalysis.

AUCextra represents an extrapolated value obtained by Clast pred/Lambda z, where Clast pred was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration is at or above the Lower Limit of quantification (LLQ) and Lambda z was the apparent terminal rate constant determined by log-linear regression analysis of the measured plasma concentrations of the terminal log-linear phase. |

CL/f was calculated as Dose/AUC0-inf, where AUC0-inf was estimated by determining the total area under the curve of the concentration versus time curve extrapolated to infinity. AUC0-inf was calculated as AUC0-t + Clast pred/Lambda Z, where Clast pred was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration was at or above the lower limit of quantification (LLQ) and Lambda Z was the apparent terminal rate constant determined from the terminal slope of the log-transformed plasma concentration curve. |
| Secondary | Apparent Volume of Distribution During Terminal Phase (Vz/f) of Racemic-Praziquantel (Rac-PZQ), R-(-)-PZQ and S-(+)-PZQ | Pre-dose, 0.25, 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 8.0, 9.0, 10.0 and 12 hours post-dose in each treatment period | Vz/f: the distribution of a study drug between plasma and the rest of the body after oral dosing. For single dose Vz/f = Dose/(AUC0-inf\*Lambda Z), where AUC0-inf = (AUC0-t + Clast pred/Lambda Z). Clastpred was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration was at or above the LLQ and Lambda Z = the apparent terminal rate constant determined from the terminal slope of the log-transformed plasma concentration curve. |
