Trial summary

It has been shown that treatment of HIV-positive women with antiretroviral medication during pregnancy reduces the risk of HIV transmission to the child. However, such treatment could lead to the selection of resistant virus strains in the mother. Read more about this study

About this study

Official title: Development of Resistance Mutations in the Human Immunodeficiency Virus (HIV) in Pregnant HIV+ Women Receiving Perinatal Antiretroviral Therapy in Israel

It has been shown that treatment of HIV-positive women with antiretroviral medication during pregnancy reduces the risk of HIV transmission to the child. However, such treatment could lead to the selection of resistant virus strains in the mother. The object of this study is to check HIV+ pregnant women for resistance mutations in HIV before and after the antiretroviral therapy they receive during pregnancy. HIV-positive newborns will also be tested, to see if a resistant virus strain was transmitted from mother to child.

Read the detailed description

The project will be performed in collaboration with the Israeli National HIV Reference Center Laboratory, which maintains a national bank of HIV-positive blood samples, and with HIV/AIDS treatment centers located throughout Israel.

An initial survey will identify retrospectively those HIV+ women who were given antiretroviral therapy while pregnant and stopped treatment after delivery. The list of HIV+ deliveries over the past five years in each participating hospital will be reviewed, and all HIV-positive women who received antiretroviral treatment during pregnancy will be invited to participate in the study project. Women who are currently pregnant, or become pregnant during the study, will be invited to participate when pregnancy is diagnosed. After obtaining informed consent, two blood samples will be obtained: one before the initiation of perinatal treatment, and the other following delivery. (Due to technical limitations, only samples with viral loads above 1000 cp/ml can be genotyped. It is expected that HIV loads will rise following cessation of antiretroviral treatment, and that almost all samples will be eligible for resistance testing.)

In addition, after obtaining maternal informed consent, samples from newborns infected perinatally with HIV will also be tested for resistance mutations, and these will be compared with the resistance pattern found in the mother.

The samples obtained will be tested for genotypic resistance mutations. The results will be transmitted to the treating physician to assist in choice of antiretroviral therapy for the women and their children, if needed. The data will also be used to establish a national database to evaluate and improve existing protocols for perinatal antiretroviral treatment, and will be used to contribute to international databases of HIV resistance. All resistance data, except that given to the health care provider(s), will be transmitted without additional identifying information.

Questions about this trial

What is this clinical trial studying?

An observational study of HIV Infections, run by Hadassah Medical Organization at 5 sites in Israel.

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 4 inclusion and 2 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: stopped early, as of the sponsor's last update on 28 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Israel. 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?

The study was stopped early (reason given: Difficulties in data collection). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Nov 2017.
