A Prospective, Observational Study of Pregnancy Outcomes Among Women Exposed to Truvada for PrEP Indication

March 29, 2018 updated by: Gilead Sciences

A Prospective, Observational Study of Pregnancy Outcomes Among Women Exposed to Truvada for PrEP Indication Nested in the Antiretroviral Pregnancy Registry

This is a prospective, observational study to describe pregnancy outcomes among HIV-1 uninfected pregnant women who are taking emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) (Truvada®) for a pre-exposure prophylaxis (PrEP) indication nested in the Antiretroviral Pregnancy Registry (APR).

Information on subjects is provided to the APR prospectively (prior to the outcome of the pregnancy being known) through their healthcare provider, with follow-up obtained from the healthcare provider following determination of the pregnancy outcome.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Number of Subjects and Subject Selection: 400 HIV-1 uninfected women who are exposed to FTC/TDF for PrEP during pregnancy stratified into 200 who decide to continue and 200 who choose to discontinue FTC/TDF for PrEP. A propensity score-matched comparison group of equal size (400 women) of HIV-positive pregnant women taking antiretrovirals.

All evaluable subjects enrolled into the APR who fulfill the inclusion criteria for the target cohort will be selected. Every year at the time of building the annual report for this study, a propensity score matched comparison group will be selected on a 1:1 ratio among all pregnant women on antiretrovirals.

Description

Key Inclusion Criteria:

  • Pregnant women
  • Part of the prospective arm of the APR Target Group Inclusion Criteria
  • HIV-1 Negative
  • Choosing to remain on FTC/TDF for PrEP during pregnancy or,
  • Choosing to discontinue FTC/TDF for PrEP during pregnancy Comparison Group Inclusion Criteria
  • HIV-1 Positive
  • On antiretroviral therapy

Key Exclusion Criteria:

  • This is an observational nested study and will monitor all reported exposures without intervention/exclusion.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
FTC/TDF for PrEP
The study has one target prospective cohort defined as HIV-1 negative women who had been prescribed FTC/TDF for pre-exposure prophylaxis (PrEP); with two strata: a) those who continue to take FTC/TDF for PrEP during their pregnancy, and b) those who decide to stop FTC/TDF for PrEP during pregnancy.
ARV population
The study has one comparison cohort defined as HIV-positive women who were on any antiretroviral (ARV) medication at the time the pregnancy was detected. This is a propensity score matched retrospective cohort selected from the prospective arm of the APR. This cohort is assembled retrospectively in order to appropriately match the subjects by calendar time and the correlates of exposure, with exposure being defined as being on FTC/TDF for PrEP vs being exposed to other ARVs.

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
Time Frame
Presence or absence of congenital malformations among infants born to HIV-1 uninfected women on FTC/TDF for PrEP
Time Frame: Year 1
Year 1

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
Time Frame
Pregnancy outcomes in HIV-1 uninfected women who choose to continue or discontinue FTC/TDF for PrEP during their pregnancy as well as HIV-infected women treated with antiretrovirals
Time Frame: Years 1, 2, and 3
Years 1, 2, and 3

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2013

Primary Completion (Actual)

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. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
March 13, 2018

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
