- NCT02795754
- Lead Sponsor
- GlaxoSmithKline
- Brief Summary
GSK2838232 is a Human Immunodeficiency Virus (HIV) maturation inhibitor being developed for the treatment of HIV in combination with other antiretroviral therapy (ART). The primary objectives of this study are to investigate the safety, tolerability, and pharmacokinetics (PK) of single and repeat doses of GSK2838232. This study will be a double-blind, placebo-controlled, single and repeat dose escalation study. This study will be conducted in two Parts: single escalating doses (Part 1A and 1B), and repeated escalating once daily (QD) doses for 11 days (Part 2) of GSK2838232 co-dosed with RTV. During Part 1A, single doses of GSK2838232 (as of active pharmaceutical ingredient-powder in bottle \[API PiB\]) 50 milligrams (mg), 100mg and 200mg will be administered with RTV. Part 1B will evaluate the relative bioavailability of single doses of crystalline active pharmaceutical ingredient (API) Immediate Release Tablet (IR) tablets versus API PiB as reference, administered with RTV. In Part 2, multiple doses of GSK2838232 will be co-administered with RTV 100mg QD for 11 days as sequential dose cohorts. Maximum duration of study participation will be approximately 10 weeks.

- 62
- Age: Between 18 and 55 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, and 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

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.
Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until one week after the last dose of study medication.
Vasectomy with documentation of azoospermia, or Male condom plus partner use of one of the contraceptive options following: Contraceptive subdermal implant that meets the standard operating procedure (SOP) effectiveness criteria including a <1% rate of failure per year, as stated in the product label; Intrauterine device or intrauterine system that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label; Oral Contraceptive, either combined or progestogen alone. Injectable progestogen; Contraceptive vaginal ring; Percutaneous contraceptive patches.
These allowed methods of contraception are only effective when used consistently, correctly and in accordance with the product label. The Investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.
