  • Research summary

    The Sponsor is developing the test medicine, VH4004280, as a potential treatment for Human Immunodeficiency Virus type 1 (HIV-1). HIV-1 is a virus that damages the cells in the immune system and weakens the immune system’s ability to fight off infections and diseases.

    In this study, healthy volunteers will be given different forms of the test medicine in single oral doses.
    We aim to answer these questions.
    * How much test medicine enters the bloodstream and how quickly does the body get rid of it?
    * How do blood levels of the test medicine compare when it is given in different forms?
    * Does the test medicine cause any important side effects?
    * Does food affect blood levels of the test medicine?

    This two-part study will take place at one non-NHS site in Nottingham.

    We plan to enrol up to 108 healthy men and women aged 18-55 years. In Part 1 up to 60 volunteers will be split evenly into up to five groups and in Part 2 up to 48 volunteers will be split evenly into up to four groups.

    In both parts, each group will be given a different form of the test medicine, and the results from Part 1 will determine which of the forms to be given in Part 2.

    Each volunteer will receive a single dose of one form of test medicine, as a tablet by mouth, with food in Part 1 and without food in Part 2. They’ll stay in the clinic for up to 7 nights on up to 1 occasion, attend up to 7 outpatient visits, and take up to 11 weeks to finish the study.

    We’ll collect blood and urine samples to:
    * do safety tests
    * measure the amount of test medicine
