Eligibility Criteria

18 Years - 59 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  1. HIV negative person, who was assigned male or female at birth, who reports sex with another man in the last year and is in good general health
  2. Aged 18-59 years
  3. Not currently taking PrEP and no plans to initiate during study
  4. Not currently taking PEP

  7. Able to provide informed consent in English
  8. No plans for relocation in the next 4 months
  9. Willing to undergo peripheral blood, urine, rectal or vaginal secretion collection, and a rectal or vaginal and cervical biopsy procedure
  10. Willing to use study products as directed
  11. Hepatitis B surface antigen (HBsAg) negative (screening lab test)
  12. Creatinine clearance >60 ml/min

Exclusion Criteria:

  1. Currently infected with hepatitis virus and/ or has liver disease
  2. Current or chronic history of kidney disease or creatinine clearance (CrCl)<60 ml/min
  3. Continued need for, or use during the 90 days prior to enrollment, of the following medications:

    1. Systemic immunomodulatory agents
    2. Supraphysiologic doses of steroids (short course steroids less than 7 days duration, allowable at the discretion of the investigators)
    3. Chemotherapy or radiation for treatment of malignancy
    4. Experimental medications, vaccines, or biologicals
  4. Intent to use HIV antiretroviral pre/post-exposure prophylaxis (PrEP or PEP) during the study, outside of the study procedures
  5. Intent to use doxycycline or other tetracycline-derived antibiotics during the course of the study, outside of the study procedures
  6. Any other clinical condition or prior therapy that, in the opinion of the investigator, would make the patient unsuitable for the study or unable to comply with the study requirements
  7. Not pregnant and no plans on getting pregnant throughout the duration of the study

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Doxycycline and Biktarvy

Arm Description

Participants will take both study drugs simultaneously at home approximately 1 hour before Visit 2 and will be instructed to take a timestamped photograph or videotape of themselves taking the dose.

Outcomes

Primary Outcome Measures

Rectal Doxycycline Concentration
Doxycycline concentration in tissue from a rectal biopsy was measured. Rectal biopsies were obtained from men. Women had the option to provide a rectal tissue sample.
Vaginal Doxycycline Concentration
Doxycycline concentration in tissue from a vaginal biopsy was measured.
Plasma Doxycycline Concentration
Doxycycline concentration in plasma was measured.

Secondary Outcome Measures

Rectal Bictegravir Concentration
Bectegravir concentration in tissue from a rectal biopsy was measured.
Vaginal Bictegravir Concentration
Bictegravir concentration in tissue from a vaginal biopsy was measured.

5. Study Description

Brief Summary
The study will determine tissue pharmacology of a single dose of doxycycline for sexually transmitted infection (STI) Post-exposure Prophylaxis (PEP).
Detailed Description
To determine tissue pharmacology of a single dose of doxycycline for STI PEP, investigators at Emory University will collaborate with the Centers for Disease Control and Prevention (CDC) to conduct a clinical trial of up to 20 men who have sex with men (MSM) and women aged 18-59, with measurement of anti-retroviral drug and doxycycline concentrations in the rectum and vaginal regions.
