Relative bioavailability study of fixed dose combination tablet formulation of GSK587323 (16mg candesartan cilexetil/12.5mg hydrochlorothiazide) under fasting conditions

Completed

• Conditions: Healthy human subjects between 18 and 65 years of age inclusive

• Registration Number: CTRI/2014/04/004526
• Lead Sponsor: GlaxoSmithKline Research and Development Limited

Brief Summary

This study aims to determine the relative bioavailability of a fixed dose combination (FDC) tablet formulation of GSK587323 (16mg candesartan cilexetil/12.5mg hydrochlorothiazide) relative to the reference product Atacand D (16mg candesartan cilexetil/12.5mg hydrochlorothiazide, Astra Zeneca, Argentina) in healthy adult subjects. This will be an open-label, randomised, single dose, two-way crossover study.

Each subject will participate in both treatment periods and will receive a single oral dose of the FDC of GSK587323 and reference Atacand D. Treatment periods will be separated by a washout period at least 7 days and no greater than 14 days. Blood samples for pharmacokinetic analysis will be taken at regular intervals after dosing. Safety will be assessed by measurement of vital signs (blood pressure, body temperature, respiration rate and pulse rate), clinical laboratory assessments, electrocardiogram measurements and review of adverse events. The study will enrol 16 healthy subjects to ensure that 14 complete the study as planned.

Inclusion Criteria

• Male and females aged between 18 and 65 years of age inclusive, at the time of signing the informed consent Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring.
• A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria,outside the reference range for the population being studied may be included only if the Investigator in consultation with the GSK Medical Monitor if required agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
• Body weight ≥ 50kg and BMI within the range 19 – 24.9kg/m2 (inclusive) Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods This criterion must be followed from the time of the first dose of study medication until the follow-up contact visit Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form ALT, alkaline phosphatase and bilirubin ≤ 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%) Based on single or averaged QTc of triplicate ECGs obtained over a brief recording period: QTcF < 450 msec.

Exclusion Criteria
