Trial overview

Official title: An Open Label, Randomized, Two Part Study to Evaluate the CYP2C8- and OATP1B1-Mediated Drug-Drug Interaction Potential of GSK1278863 with Pioglitazone and Rosuvastatin as Victims and Trimethoprim as Perpetrator in Healthy Adult Volunteers
Trial description: This study will be a two-part with an open-label, single oral dose, two-way crossover study design. Part A and Part B of the study are independent and may be conducted in parallel. The Part A of the study will assess the effect of an oral dose of GSK1278863 on the pharmacokinetics of a CYP2C8 (pioglitazone) and OATP1B1 (rosuvastatin) probe substrate in order to determine the potential for clinically-significant drug interactions with CYP2C8 and OATP1B1 substrates. The Part B of the study will assess the effect of a weak CYP2C8 inhibitor (trimethoprim) on the pharmacokinetics of GSK1278863 and its six predominant metabolites. Part A will be conducted in approximately 30 healthy subjects, having a randomized study design. There will be approximate 7-day washout period between each dosing period. Part B will be conducted in approximately 20 healthy subjects, having single sequence study design. Follow up will be conducted within 7 to 10 days after the last dose in both Part A and B. The total duration of a subject’s involvement in the part A of the study will be approximately 8 weeks (Screening to Follow-up) and in part B will be approximately 7 weeks (Screening to Follow-up).

    Accepts healthy volunteers
    Yes
    • Subjects who are between 18 and 65 years of age, inclusive at the time of signing the informed consent form.
    • Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and ECG monitoring obtained at the screening visit. The determination of clinical significance will be made by the investigator and the GlaxoSmithKline (GSK) Medical Monitor and will require that the finding is unlikely to introduce additional risk factors or interfere with the study procedures, or the integrity of the study.
    • Alanine transaminase (ALT), alkaline phosphatase and bilirubin >1.5xUpper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
    • Corrected QT interval(QTc): QT interval corrected for heart rate according to Bazetts formula (QTcB) >450 milliseconds (msec), The QTc must be the QT interval corrected for heart rate according to Bazetts formula (QTcB). For purposes of data analysis, QTcB will be used.
