Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  1. The ability to understand and sign a written informed consent form, prior to participation in any screening procedures and must be willing to comply with all study requirements
  2. Male or non-pregnant, non-lactating females.
  3. Between 18 to 65 years, inclusive
  4. Body Mass Index (BMI) of 18 to 35 kg/m2, inclusive
  5. ALT, alkaline phosphatase and bilirubin ≤ 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%). A single repeat is allowed for eligibility determination.
  6. Women of childbearing potential must be using an adequate method of contraception to avoid pregnancy throughout the study and for a period of at least 4 weeks after the study. Any contraception method must be used consistently, in accordance with the approved product label and for at least 4 weeks after discontinuation of IMP.
  7. Men who have partners who are women of childbearing potential must be using an adequate method of contraception to avoid pregnancy in their partner throughout the study and for a period of at least 4 weeks after the study. Any contraception method must be used consistently, in accordance with the approved product label and for at least four weeks after discontinuation of IMP.
  8. Willing to consent to their personal details being entered onto the TOPS database
  9. Willing to provide proof of identity by photographic ID at screen and any subsequent visit
  10. Registered with a GP in the UK

Exclusion Criteria:

  1. Any clinically significant acute or chronic medical illness
  2. Evidence of organ dysfunction or any clinically significant deviation from normal in physical examination, vital signs, ECG or clinical laboratory determinations
  3. Positive blood screen for hepatitis B surface antigen or C antibody
  4. Positive blood screen for HIV-1 or 2 by antibody/antigen assay
  5. Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
  6. History or presence of allergy to the study drugs and their components
  7. Current or recent (within three months) gastrointestinal disease
  8. Known intolerance of lactose monohydrate, sunset yellow aluminium lake (E110), and patients with galactose intolerance, the Lapp lactase deficiency, or glucose-galactose malabsorption
  9. Clinically relevant alcohol or drug use (positive urine drug screen) or history of alcohol or drug use considered by the Investigator to be sufficient to hinder compliance with treatment, follow-up procedures or evaluation of adverse events. Smoking is permitted, but tobacco intake should remain consistent throughout the study
  10. Exposure to any investigational drug (or placebo) or participation in a clinical study involving the donation of blood samples within three months of first dose of study drug
  11. Use of any other drugs (unless approved by the Investigator), including over-the-counter medications and herbal preparations, within two weeks prior to first dose of study drug, unless approved/prescribed by the Principal Investigator as known not to interact with study drugs.
  12. Females of childbearing potential without the use of effective non-hormonal birth control methods, or not willing to continue practising these birth control methods for at least four weeks after the end of the treatment period

5. Study Description

Brief Summary
Study to assess the pharmacokinetics of plasma doravirine once daily over 72 hours following drug intake cessation at steady-state in healthy volunteers
Detailed Description
The administration of combination antiretroviral therapy (cART) to HIV-infected patients has been associated with a dramatic reduction in AIDS-related morbidity and mortality. The key to successful HIV drug treatment is adhering to the prescribed combination every day. The approval of single tablet combinations (STRs) provides HIV care providers with a "one tablet once a day" therapy, making adherence much easier for patients. However, in HIV therapy, successful adherence also means attention to intervals between doses or dietary restrictions. Ideally, to guarantee long-term virological response, HIV-infected patients should take their cART every day at the same time. However, cART is for life and doses can be forgotten or delayed. For this study 14 healthy volunteers will receive Pifeltro® (doravirine 100mg tablets) daily for 7 days to reach steady state. Following the last dose samples will be taken for pharmacokinetic testing over 72 hours. The incidence of adverse events between enrolment to the study (day 1) and last visit (day 20-23) will be recorded. Blood, urine and faecal samples from study subjects will be taken for use in planned exploratory research and for use in future research: Analyses looking at genes which affect drug disposition (pharmacogenomics); the impact of doravirine intake on platelet function and markers of platelet and endothelial cell activation; metabolic changes associated with doravirine.
