March 26, 2019 updated by: Infectious Diseases Institute, Makerere University

A Pharmacokinetic Evaluation of Etonogestrel Implant in HIV-infected Women on Darunavir Versus Ripilvirine-based Antiretroviral Therapy

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

Despite the benefits of hormonal contraceptives, significant drug-drug interactions (DDIs) with some antiretroviral therapies (ART) represent a barrier to effective family planning methods for HIV-infected women. It is therefore critical to generate data on the combined use of hormonal contraceptives and ART. This study is a prospective, non-randomized, open-label, parallel, two-group, sparse-sampling pharmacokinetic study to describe etonogestrel (ENG) pharmacokinetic (PK) parameters in two treatment groups (rilpivirine or darunavir- based ART) in 60 HIV-1 infected women. The primary endpoint is the comparison of the mean ENG concentrations at month 6 between the rilpivirine or darunavir treatment groups versus historical controls. This study will provide information on effective ART options for HIV positive women who opt for the contraceptive implant as a family planning method of choice.

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.

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 to 45 years (ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  1. Evidence of a personally signed and dated informed consent document indicating that the participant has been informed of all pertinent aspects of the study.
  2. Participants who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
  3. Women age 18 years to 45 years
  4. Diagnosed with HIV infection
  5. Medically eligible for the ENG subdermal implant as a contraceptive method based on the WHO Medical Eligibility Criteria for Contraceptive Use
  6. Receiving EFV- or LPV/r-based ART for a minimum of 1 year
  7. If not abstinent, must agree to use an effective non-hormonal method of contraception for the duration of the study including male and female condoms or the copper-T intrauterine device.

  8. Participants must have a negative urine pregnancy test at entry and report no unprotected sex since the last menstrual period or in the last two weeks.

Exclusion Criteria:

  1. HIV RNA greater than 50 copies/mL at the screening visit
  2. CD4 count below 200 cells/mm3 at the screening visit
  3. History of virologic failure on the current regimen (two consecutive viral load results equal to or greater than 400 copies/mL)
  4. Serum hemoglobin less than 9.0 g/dl at screening
  5. Elevations in serum levels of alanine transaminase (ALT) above 5 times the upper limit of normal
  6. Elevations in serum creatinine above 2.5 times the upper limit of normal
  7. Use of drugs known to be contraindicated with ENG, RPV (for women taking EFV-based ART), or DRV (for women taking LPV-based ART) within 30 days of study entry. Due to the dynamic nature of drug interactions related to antiretroviral therapy, the study team will review all concomitant medications at screening based on the US Department of Health and Human Services drug interaction table and the University of Liverpool HIV drug interaction tables (www.hiv-druginteractions.org)
  8. Currently pregnant or postpartum <30 days at study entry.
  9. Breastfeeding women within 6 months of delivery.
  10. Patients with a history of hypersensitivity to ENG implant, undiagnosed vaginal bleeding, diagnosed or suspected sex hormone dependent neoplasia, benign or malignant liver tumor, or thromboembolic disease.

  11. Presence of any active clinically significant disease or life-threatening disease that, in the investigator's opinion, would compromise the subject's safety or outcome of the study.
