About this study
The purpose of this study is to compare the incidence of Zika virus (ZIKV) infection among pregnant women with and without Human Immunodeficiency Virus (HIV) infection and to determine the risk of adverse maternal and child outcomes associated with ZIKV/HIV co-infection across clinical sites in the continental United States (U.S.), Puerto Rico (P.R.) and Brazil.
Read the detailed description
This is a two-phase prospective international cohort study of pregnant women and their infants from those pregnancies whose goals are to compare the incidence of ZIKV infection among pregnant women with and without HIV infection and to determine the risk of adverse maternal and child outcomes associated with ZIKV/HIV co-infection across clinical sites in the continental U.S., P.R. and Brazil.
Phase I will enroll pregnant women/infant pairs who are: (1) infected with HIV only; (2) infected with ZIKV only; (3) infected with HIV and ZIKV; and (4) not infected with HIV or ZIKV. Phase I will assess the feasibility of enrolling a total of 200 pregnant women/infant pairs within a year, with a target of 150 HIV-infected women, 50 HIV-uninfected women from the continental U.S. sites only, and a minimum of 20 who are co-infected with HIV and ZIKV by the end of pregnancy.
Should the feasibility of Phase I prove successful, Phase II will commence by enrolling up to 1,800 additional pregnant women/infant pairs to the 4 groups described above. The comparison group of HIV-uninfected pregnant women/infant pairs from P.R and Brazil (ZIKV-infected and uninfected) will be obtained from data collected in the concurrent International Prospective Observational Cohort Study of Zika in Infants and Pregnancy (ZIP study).
All HIV-infected and uninfected study participants will be tested for ZIKV. Enrolled women will be followed throughout their pregnancy and up to six weeks postpartum. Infants born to enrolled women will be followed for a full year after birth. Thereafter, the infants born to women at continental U.S. and P.R. sites also implementing the Surveillance Monitoring for Antiretroviral Therapy (ART) Toxicities (SMARTT) study may be followed up yearly until adulthood through SMARTT depending on the availability of funds.

What is being measured
The primary outcome is the main question the study is designed to answer.
Enrollment (150 HIV-infected and 50 HIV-uninfected Pregnant Women Within One Year, With a Minimum of 20 of These Women Having HIV/ZIKV Co-infection by Their End of Pregnancy).
This outcome measured feasibility of enrolling 150 pregnant women living with HIV and 50 pregnant women without HIV, with a minimum of 20 of these women having HIV/ZIKV co-infection by their end of pregnancy
Measured: At the time of delivery of all those enrolled up to 1 year after the first enrollment
Viral Suppression (in HIV-infected Women With ZIKV Co-infection Compared to Those Without ZIKV Co-infection During Pregnancy) at the Time of Delivery.
This outcome intended to measure HIV suppression at the time of delivery among women living with HIV with and without ZIKV infection during pregnancy. Note there were no women with ZIKV infection in pregnancy. Viral suppression was defined at different thresholds (<40 copies/mL, <400 copies/mL, <1000 copies/mL).
Measured: Maternal viral load at delivery
Incidence of ZIKV Infection (Among Pregnant Women With HIV Infection Compared to Those Without HIV Infection).
Cumulative incidence of ZIKV infection during pregnancy (among pregnant women with HIV infection compared to those without HIV infection).

Adverse pregnancy outcomes included miscarriage, stillbirth and preterm delivery. Note there were no women with ZIKV infection in pregnancy.
Miscarriage was defined as fetal demise at <20 weeks of gestation. Stillbirth was defined as fetal demise at ≥20 weeks of gestation. Preterm delivery was defined as delivery at <37 weeks of gestation.
Measured: At time of delivery
Incidence of Vertical Transmission of HIV and/or ZIKV (in Women Co-infected With HIV and ZIKV and Women Infected With Either HIV or ZIKV Alone).
Cumulative incidence of confirmed HIV infection among enrolled infants. Note there were no women with ZIKV infection in pregnancy so therefore no risk of transmission of ZIKV to any infants.
Measured: Infant birth to 12 months

Cumulative incidence of congenital malformations. Note there were no women with ZIKV infection in pregnancy.
Observed major congenital malformations included: anhydramnios, cerebral ventriculomegaly, clubfoot (unresolved), Down syndrome, hydrops, hypospadias, patient ductus arteriosus, polydactyly (left foot), Potter syndrome, short stature, syndactyly (left foot, 1st and 2nd toes).
Observed minor congenital malformations included: clubfoot (resolved), cryptorchidism (bilateral), dislocated hip, heart defect (patent foramen ovale), heart murmur (unresolved), hemangioma, hip dysplasia, hydrocele, inguinal hernia, head circumference -3 ≤ z-score <-2, persistent ductus arteriosus (resolved), plagiocephaly, restrictive ductus arteriosus, renal pyelectasis, sacral dimple, small perimembranous ventricular septal defect, stenosis of nasolacrimal duct, umbilical hernia.
Measured: Infant birth, 3 months
Incidence of Other Adverse Outcomes Among Offspring of Women Co-infected With HIV and ZIKV, Women Infected With Either HIV or ZIKV Alone.
Other adverse outcomes included microcephaly, neonatal dealth, central nervous system (CNS) malformation, hydrops, and ocular abnormalities. Note there were no women with ZIKV infection in pregnancy.
Microcephaly was defined as head circumference less than a z-score of -3 at birth or 3 month visit.

Questions about this trial
What is this clinical trial studying?
An observational study of HIV and Zika Virus, run by Westat at 11 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in Brazil, United States, Puerto Rico. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 14 Jan 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
