Eligibility Criteria
Inclusion
- Healthy HIV-positive adults aged 18-65, inclusive on the date of screening, with documentation of at least one positive HIV test. Healthy is defined as no clinically relevant abnormalities that would interfere with the interpretation of results, or pose unnecessary risk onto volunteers due to study procedures.
- Receiving an antiretroviral regimen containing tenofovir+emtricitabine with raltegravir (Group A) or dolutegravir (Group B) for \> 3 months, with blood plasma HIV RNA \< 50copies/mL for at least 4 weeks, or a 2 log decrease in baseline blood plasma HIV RNA.
- Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the trial.
- Documentation of at least 80% adherence to antiretroviral regimen, through clinician or self-report, with no missed doses in the 3 days prior to the inpatient visit.
- Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures.
- Women of childbearing potential must be utilizing at least one acceptable form of birth control.
Exclusion
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, or neurologic disease that would pose unnecessary risk or interfere with study results. Subjects will be excluded for any condition that would increase risk from sedation, endoscopy, or biopsy.
- Subjects with a history of having a gastrectomy, colostomy, ileostomy, or any other clinically significant procedure altering the gastrointestinal tract, or any condition possibly affecting drug absorption.
- Subjects with inflammatory bowel diseases (ulcerative colitis or Crohn's disease).
- Female subjects who are currently pregnant or breastfeeding, or planning to become pregnant during the study period.
- Subjects who are unwilling to refrain from insertion of medical/recreation devices and products into the rectum, and from receptive anal intercourse, for 72 hours before inpatient study visit and through 7 days after the last biopsy unless instructed otherwise by the investigators.
- A positive urine drug screen.
- Untreated rectal sexually transmitted infection at screening.
- Treatment with an investigational drug within 2 months preceding study enrollment.
- Participated in a gastrointestinal biopsy study in the 3 months preceding study enrollment.
- Participants with a history of clotting or bleeding disorders.
- Participants with a history of abnormal reaction to, or complication from, conscious sedation or anesthesia
- Subjects who are unwilling or unable to comply with the following dietary restrictions in regard to study procedures, including a clear liquid diet during bowel preparation and a period of NPO (nil per os) prior to the colonoscopy. While confined, the total daily nutritional composition will be 50% carbohydrate, 15% protein, and 35% fat. The daily caloric intake should not exceed 3200kcal.
- Abnormalities of the colorectal mucosa, or significant colorectal symptom(s), which in the opinion of the clinician represents a contraindication to biopsy (including but not limited to presence of any unresolved injury, infectious or inflammatory condition of the local mucosa, and presence of symptomatic external hemorrhoids).
- Any other reason or condition that in the judgment of the investigators would make participation in the study unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving the study objectives.
