Trial overview
Official title: An Open-label, Randomized, Single Dose, Three-way Crossover, Six Sequence Pilot Study to Determine the Relative Bioavailability of Candesartan Cilexetil 16mg From Two Candidate Tablet Formulations of GW615775 Relative to One 16mg Tablet of Reference Candesartan Cilexetil in Healthy Adult Human Subjects Under Fasting Conditions
Trial description: This study will investigate the relative bioavailability of two candidate tablet formulations of 16 milligram (mg) Candesartan cilexetil (GW615775) compared with the reference product ATACAND™ containing 16 mg Candesartan cilexetil in healthy human subjects. This is an open-label, randomized, single dose, three-way crossover, six sequence study enrolling 18 healthy human subjects to ensure at least 14 subjects complete the study as planned. Each subject enrolled will participate in all three treatment periods and will be assigned to one of the six treatment sequences, in accordance with the randomization schedule. The treatment periods will be separated by a washout period of at least 7 days and no more than 14 days between dosing occasions. A follow up visit will be conducted 14-21 days post last dosing. ATACAND is a registered trademark of the AstraZeneca group of companies.

Accepts healthy volunteers
Yes
- Male and females aged between 18 and 65 years of age inclusive, at the time of signing the informed consent.
- Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring.
- Alanine aminotransferase and bilirubin >1.5x upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
Inclusion and exclusion criteria
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 the investigator or medically qualified designee 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 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 >= 50 kilograms (kg) and Body Mass Index within the range 19 –24.9 kg/meter (m)^2 (inclusive).
- Female subject: is eligible to participate if she is not pregnant (as confirmed by a negative serum human chorionic gonadotrophin test), not lactating, and at least one of the following conditions applies: Non-reproductive potential defined as: Pre-menopausal females with documented tubal ligation, or documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, or hysterectomy, or documented bilateral oophorectomy. Postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone and estradiol levels consistent with menopause [refer to laboratory reference ranges for confirmatory levels]). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment. Reproductive potential and agrees to follow one of the options listed below in the GlaxoSmithKline (GSK) Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) requirements from 30 days prior to the first dose of study medication and until [at least five terminal half-lives OR until any continuing pharmacologic effect has ended, whichever is longer] after the last dose of study medication and completion of the follow-up visit. GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in FRP. This list does not apply to FRP with same sex partners, when this is their preferred and usual lifestyle or for subjects who are and will continue to be abstinent from penilevaginal intercourse on a long term and persistent basis: Contraceptive subdermal implant that meets the effectiveness criteria including a <1% rate of failure per year, as stated in the product label.
