Safety and Acceptability Study of Non-occupational Prophylaxis (PEP) Following Potential Exposure to HIV (BMS PEP)

June 24, 2025 updated by: Kenneth H. Mayer, MD

A Phase IV Open-label Evaluation of Safety, Tolerability and Patient Acceptance of Atazanavir Boosted With Ritonavir Combined With a Fixed-dose Formulation of Tenofovir DF and Emtricitabine for nPEP Following Potential Exposure to HIV-1

This study will evaluate how safe and tolerable a combination of taking three-drugs will be for the purpose of preventing HIV transmission after a high-risk sexual contact exposure in HIV uninfected adults.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participants are given a regimen containing tenofovir disoproxil fumarate (TDF) 300mg and emtricitabine (FTC) 200mg fixed-dose combination tablet (TDF/FTC) once daily, and atazanavir, one 300mg tablet and one 100 mg ritonavir given once daily,for 28 days.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. Age of 18 at time of first visit.
  2. HIV uninfected on the basis of a negative HIV Rapid Test
  3. Possible non-occupational exposure to HIV-1, recent enough to permit receiving the first dose of study medication within 72 hours from the end of the exposure.

Exclusion Criteria:

  1. Women who are actively trying to become pregnant.
  2. Pregnancy and/or Breastfeeding.
  3. Known self report of Chronic Hepatitis B infection or prior antiretroviral therapy for hepatitis B.
  4. Known intolerance or allergy to study drugs.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety of Regimen - Symptoms
Time Frame: Visit 3- Day 30
Number of subjects who experienced moderate-to-severe symptoms on the symptom-directed physical exam at or before visit 3.
Visit 3- Day 30
Safety of Regimen - Adverse Events/Serious Adverse Events Considered Related
Time Frame: visit 3 - day 30
Number of subjects who experience adverse or serious adverse events that are considered related to the use of the drug regimen at or before visit 3.
visit 3 - day 30
Safety of Regimen - Unsafe Biological Test
Time Frame: visit 3 - day 30
Number of subjects who have an unsafe biological test result as part of the laboratory screen for safety levels (e.g., CBC, Creatinine, etc.) at or before visit 3.
visit 3 - day 30

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Awareness of NPEP
Time Frame: Visit 2- Day 14
Assess awareness as measured by how many participants had initially heard of NPEP prior to the incident exposure
Visit 2- Day 14
Adherence Rate - Overall
Time Frame: Visit 3- Day 30
Adherence to the regimen will be assessed by whether the regimen was completed as prescribed or not. χ2 tests will be used to assess differences in the proportion of both completion and adherence between participants in the current study and participants in previous studies of NPEP at Fenway Health (historical controls).
Visit 3- Day 30
Prior nPEP Use
Time Frame: Visit 2- Day 14
Number of participants who had used nPEP prior to participation in the study.
Visit 2- Day 14
Adherence - Degree of Adherence
Time Frame: Visit 1- Day 28
Number of participants who completed prescribed regimen
Visit 1- Day 28

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
