About this study

Official title: A Phase I Trial of the Safety, Tolerance, and Pharmacokinetics of Oral Ritonavir Co-Administered With Lamivudine (3TC) and Zidovudine (ZDV) in HIV-1-Infected Pregnant Women and Their Infants

The purpose of this study is to see if it is safe and effective to give ritonavir (RTV) plus lamivudine (3TC) plus zidovudine (ZDV) to HIV-infected pregnant women during pregnancy and to their babies after birth.

Pregnant women who are HIV-positive are at risk of giving HIV to their babies during pregnancy or delivery. It is important to learn how to prevent HIV-positive pregnant women from giving HIV to their babies. RTV and ZDV have been shown to be safe and effective against HIV in adults. The combination of 3 anti-HIV drugs (RTV, 3TC, and ZDV) may help prevent HIV infection from mother to infant but studies are needed to determine whether they are safe and effective during pregnancy.

Read the detailed description

Controlled studies of the pharmacokinetics and safety of new drugs are critical to the development of alternative therapies for the prevention of perinatal transmission of HIV-1. The dosing regimen of RTV and ZDV used to treat pregnant women in this study has been shown to be safe and effective against HIV in adults. Little is known about the metabolism and tolerance of these drugs during pregnancy, and Phase I studies are needed to determine dosage, safety, and tolerance. Protease inhibitors in combination with other antiretroviral drugs may help reduce the rate of perinatal transmission of HIV-1.

Pregnant women start with RTV (increasing gradually over a few days) plus 3TC plus ZDV until active labor. Intrapartum, women receive RTV plus 3TC plus ZDV, then postpartum (after cord clamped until 12 weeks postpartum), RTV plus 3TC plus ZDV. [AS PER AMENDMENT 2/9/99: For maternal dosing, one Combivir tablet (containing 3TC and ZDV) may be administered in place of the individual agents 3TC and ZDV. During the intrapartum period, Combivir is held and the patient follows intrapartum 3TC/ZDV dosing. During the intrapartum period, no RTV is given after the onset of active labor. During the postpartum period, RTV is begun as soon as oral intake is allowable following delivery. During the postpartum period, Combivir may be resumed. All subjects who prematurely discontinue study treatment should continue to be followed for the duration of the study.] [AS PER AMENDMENT 9/28/99: During the intrapartum period, RTV is given at the start of active labor.] Infants begin 3TC and ZDV as soon as oral intake is tolerated. Infants participate in one of two cohorts. The first four infants delivered (Cohort 1) receive RTV as a single dose between Days 8 and 12. The next six infants delivered (Cohort 2) start RTV at 2-3 days of life. The dosing schedule is based on Cohort 1 drug pharmacokinetics data. [AS PER AMENDMENT 2/9/99: Cohort 1 is expanded to seven mother/infant pairs.] [AS PER AMENDMENT 9/28/99: Cohort 1 is expanded to eight mother/infant pairs.] Both maternal and infant blood is drawn to assess drug pharmacokinetics. Cervical secretions are collected to assess presence of virus. In addition, all placentas are examined by histopathology to determine the role of placenta on preterm delivery in women receiving combination antiretroviral therapy.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ritonavir, Lamivudine and Zidovudine in people with HIV Infections and Pregnancy, run by National Institute of Allergy and Infectious Diseases (NIAID) at 5 sites in United States.

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 5 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 29 Oct 2021. 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 United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

On the ClinicalTrials.gov record for NCT00000888, which also lists 1 linked publication.

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 29 Oct 2021.
