Bioequivalence Study in Healthy Volunteers of a New Paediatric Formulation of Valacyclovir

• Status: Completed
• Trial end date: 2015-07-01
• Target enrollment: 0
• Participant gender: All

Summary

A new paediatric formulation (oral liquid) has been developed for flexible and accurate dosing of valacyclovir in children. To establish the bioavailability of this new formulation, healthy volunteers will be exposed to the new formulation and to valacyclovir tablets. The concentration of valacyclovir in their blood after exposure to the oral liquid will be measured and compared to the tablet.

• Phase: Phase 1

• Subject has a Quetelet Index (Body Mass Index) of 18 to 30 kg/m2, extremes included.

• Subject has signed the Informed Consent Form prior to screening evaluations.

• Subject is in good age-appropriate health condition as established by medical history, physical examination, electrocardiography, results of biochemistry, haematology and urinalysis testing within 4 weeks prior to the first dose. Results of biochemistry, haematology and urinalysis testing should be within the laboratory's reference ranges (see Appendix A). If laboratory results are not within the reference ranges, the subject is included on condition that the investigator judges that the deviations are not clinically relevant. This should be clearly recorded.

• Subject has a normal blood pressure and pulse rate, according to the investigator's judgement.

• Female subject is either not of childbearing potential, defined as postmenopausal for at least 1 year or is of childbearing potential with adequate contraception (e.g. hysterectomy, bilateral tubal ligation, (nonhormonal) intrauterine device, total abstinence, double barrier methods, vasectomized partner).

Exclusion Criteria:

• Documented history of sensitivity/idiosyncrasy to medicinal products or excipients.

• Positive HIV, hepatitis B or C test.

• Therapy with any drug (for two weeks preceding dosing), except for acetaminophen.

• Relevant history or presence of pulmonary disorders (especially COPD), cardiovascular disorders, neurological disorders (especially seizures and migraine), gastro-intestinal disorders, renal and hepatic disorders, hormonal disorders (especially diabetes mellitus), coagulation disorders.

• Relevant history or current condition that might interfere with drug absorption, distribution, metabolism or excretion.

• History of or current abuse of drugs, alcohol or solvents.

• Inability to understand the nature and extent of the trial and the procedures required.

• Participation in a drug trial within 60 days prior to the first dose.

• Donation of blood within 60 days prior to the first dose.

• Febrile illness within 3 days before the first dose.

• Pregnant female (as confirmed by an HCG test performed less than 4 weeks before the first dose) or breast-feeding female.
