NCT01689285

Last verified: September 2014
  Purpose

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.

Further study details as provided by Radboud University:

Primary Outcome Measures:
  • Geometric Mean Ratios and 90% confidence intervals of pharmacokinetic parameters of acyclovir taken as valacyclovir tablet or oral solution [ Time Frame: up to 8 days ] [ Designated as safety issue: No ]
    bioequivalence will be determined by comparing AUC0-inf, Cmax and tmax of both formulations in healthy adult volunteers.


Secondary Outcome Measures:
  • Determine the safety profile of a single dose of valacyclovir oral solution [ Time Frame: day 1 and 8 ] [ Designated as safety issue: Yes ]
    healthy volunteers will be interviewed for adverse events, laboratory safety assessments will be performed.


Estimated Enrollment: 16
Study Start Date: December 2013
Estimated Study Completion Date: January 2016
Estimated Primary Completion Date: July 2015 (Final data collection date for primary outcome measure)

Active Comparator: valacyclovir tablet
Administration of 500 mg once daily on day 1 (group A) or on day 8 (group B)
Drug: valacyclovir tablet
16 healthy adult volunteers (18-55 yr) will be exposed to one tablet
Other Name: Zelitrex
Experimental: valacyclovir oral solution

  Eligibility

Ages Eligible for Study:   18 Years to 55 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Subject is at least 18 and not older than 55 years of age at screening.
  • Subject does not smoke more than 10 cigarettes, 2 cigars, or 2 pipes per day for at least 3 months prior to the first dosing
  • 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.
