History of Changes


The purpose of this study is to examine the safety and tolerability of ZDV when given to premature infants born to HIV-positive women to prevent HIV infection.

ZDV has been used successfully to prevent the transmission of HIV from mother to child during pregnancy and birth. However, ZDV has been given to very few premature babies, and the best dose to use has not yet been determined.

Condition Intervention
HIV Infections

Drug : Zidovudine

Study Type: Interventional
Study Design: Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: The Safety, Tolerance, and Pharmacokinetics of Zidovudine in Premature Infants Exposed to HIV.

Further study details as provided by National Institute of Allergy and Infectious Diseases (NIAID):

Enrollment: 35
Study Completion Date: February 2000

Detailed Description:

In the preliminary group of premature infants, those receiving q 6h dosing had an average trough concentration of 7.3 uM (18%). However, the premature infants in the preliminary pharmacokinetic study did not have long term follow-up to assess toxicity. Due to the potential for altered ZDV pharmacokinetics and increased toxicity in this population, an evaluation of ZDV pharmacokinetics in premature infants is proposed.
Premature infants less than or equal to 34 weeks gestational age at birth and begun on ZDV by their clinical caregivers will be entered into the protocol within the first 5 days of life. Upon entry, ZDV will be administered every 12 hours intravenously or orally. The study will require 9 serum samples for ZDV assay collected over 30 days, some additional clinical laboratory tests collected over 12 weeks, collection of 3 spot urine samples, and collection of routine clinical data.



Ages Eligible for Study: up to 5 Days  
Sexes Eligible for Study: All  
Accepts Healthy Volunteers: No
