About this study

Official title: A Phase IV Randomized Double-Blind Placebo-Controlled Trial to Evaluate the Safety of Immediate (Antepartum-Initiated) Versus Deferred (Postpartum-Initiated) Isoniazid Preventive Therapy Among HIV-Infected Women in High Tuberculosis (TB) Incidence Settings

Tuberculosis (TB) is a leading cause of death among HIV-infected persons in low-income settings and can be a serious complication for HIV-infected pregnant women and their infants. Isoniazid (INH) preventive therapy (IPT) is effective in preventing TB infection in HIV-infected adults, but the safety of IPT in pregnant women is unknown. This study evaluated the safety of IPT among HIV-infected pregnant women.

Read the detailed description

TB disease is the most common HIV-related opportunistic infection and is a leading cause of death among HIV-infected persons in low-income settings. When TB occurs during or soon after pregnancy, it can cause complications for the mother as well as infant TB or death. Infant TB is very difficult to diagnose, and up to half of infant TB cases are caused by maternal TB. It has been shown that treatment for active TB is safe and effective during pregnancy and that IPT is safe and effective in preventing TB infection in HIV-infected adults. However, the safety of IPT in HIV-infected pregnant women is not known, especially in regard to its combination with highly active retroviral therapy (HAART). This study evaluated the safety of immediate (antepartum, or before delivery) versus deferred (postpartum, or after delivery) IPT among HIV-infected pregnant women in high TB incidence settings.

HIV-infected pregnant women were randomly assigned (1:1) to one of two arms: Arm A (immediate/antepartum INH) and Arm B (deferred/postpartum INH group). Women in both arms received oral prenatal multivitamins and pyridoxine (vitamin B6) once daily from study entry through Week 40 postpartum.

Study visits for women occurred at screening, entry, every 4 weeks until labor and delivery, at labor and delivery, and every 4 weeks after delivery until 48 weeks postpartum. Visits consisted of giving a medical history and undergoing a physical exam and blood collection; all visits through the delivery visit also included an obstetrical exam. Presence of HIV infection was documented at screening and a tuberculin skin test (TST) was administered at the delivery visit and at the Week 44 postpartum visit. Study visits for infants occurred at birth and at several time points through Week 48. These visits included a medical history, physical exam, and blood collection. Intensive pharmacokinetic (PK) samples, that is, samples taken at many different time points within a 24-hour test period, were collected from a small subset of women, one test period at antepartum and one at postpartum. Sparse PK samples, that is, samples taken at fewer time points within the test period, were collected on all women, once each at antepartum and postpartum.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Isoniazid (INH) in people with HIV Infections and Tuberculosis, run by National Institute of Allergy and Infectious Diseases (NIAID) at 13 sites in 8 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 12 inclusion and 12 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 5 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in South Africa, Zimbabwe, Botswana, Haiti, India and 3 more countries. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Nov 2018). 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?

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

What does the primary outcome measure?

Incidence Rate of Combined Endpoint: Grade 3 or Higher Adverse Events (AEs) Related to Treatment, or AE Causing Discontinuation of Treatment (time frame: Measured from study entry through Week 48 after birth). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01494038, which also lists 6 linked publications.

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 5 Nov 2021.
