Bioequivalence Study of Coated Cesol Tablet Formulation Versus Biltricide

A Phase I, Open-label, Randomized, Four-period, Crossover, Fully Replicated, Reference-scaled, Single Center Study to Assess the Bioequivalence of a Single Oral Dose of 1200 mg of the Coated Cesol Tablet Formulation Versus Comparator Biltricide® in Healthy Male Volunteers

The purpose of this study is to assess the bioequivalence (BE) of new coated Cesol tablet (Test) versus Biltricide tablets (Comparator) in healthy male participants. Praziquantel (rac-PZQ) is the active ingredient for Cesol and Biltricide tablets.

Inclusion Criteria:

• Participants who are overtly healthy as determined by medical evaluation, including medical history, physical examination, laboratory tests, and cardiac monitoring
• Nonsmoker (=0 cigarettes, pipes, cigars or others) since at least 3 months
• Have a body weight within 55.0 to 95.0 kilogram (kg) and body mass index within the range of 18.5 to 29.9 kilogram per meter squared (kg/m^2)
• Electrocardiogram recording (12-lead) without signs of clinically relevant pathology in particular heart-rate corrected [QTc] (Bazett) <450 milliseconds (ms)
• Vital signs should be in normal range (systolic blood pressure: 90 to 140 millimeters of mercury [mmHg]; diastolic blood pressure: 50 to 90 mmHg; pulse rate: 50 to 90 beats per minute [bpm]; auricular body temperature between 35.9 degree centigrade [°C] to 37.6°C)
• Are males agreeing to refrain from donating sperm, Use a male condom when having sexual intercourse with a woman of child-bearing potential, who is not currently pregnant, and advise her to use a highly effective contraceptive method with a failure rate of less than (< )1 percent (%) per year
• Other protocol defined inclusion criteria could apply

Exclusion Criteria:

• Any condition, including any clinically relevant abnormality in the safety laboratory parameters as judged by the Investigator, that in the Investigator's opinion constitutes an inappropriate risk or a contraindication for participation in the study or that could interfere with the study objectives, conduct, or evaluation
• Have positive results from serology examination for Hepatitis B surface antigen (indicative of active Hepatitis B), Hepatitis C Virus or Human Immunodeficiency Virus (Human Immunodeficiency Virus 1/2 antibodies)
• Participants who have used drugs that may affect the pharmacokinetics of rac-PZQ from 15 days before dosing until the last PK sample, example., phenytoin, barbiturates, primidone, carbamazapine, oxcarbazepine, topiramate, felbamate, rifampicin, nelfinavir, ritonavir, griseofulvin, oral ketoconazole
• Positive test for drugs of abuse (including alcohol) at Screening and prior to each dosing
• Unlikely to comply with the protocol requirements, instructions and study-related restrictions; example, uncooperative attitude, inability to return for follow-up visits, and improbability of completing the study
• Participant is the Principal Investigator or any Sub investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the study
• Inability to communicate or cooperate with the Investigator (example. language problem, illiterates, poor mental status) or to comply with the requirements of the entire study, including dietary restrictions
• Vulnerable participants (example., persons kept in detention).
• Legal incapacity or limited legal capacity
• Other protocol defined exclusion criteria could apply
