Perinatal Antiretroviral Intensification for PMTCT of HIV in Late Comers

Phase 3

Completed

• Conditions: HIV Infections
• Interventions: Drug: Nevirapine, zidovudine, lamivudine

• Registration Number: NCT01511237
• Lead Sponsor: Institut de Recherche pour le Developpement

Brief Summary

The purpose is to evaluate the efficacy of maternal and infant perinatal antiretroviral prophylaxis intensification for the prevention of mother-to-child intrapartum transmission of HIV-1 in women receiving less than 8 weeks of antiretroviral prophylaxis during pregnancy.

Detailed Description

Design: a multicenter, phase III, single-arm trial.

Perinatal antiretroviral intensification (study treatment) is defined as the addition to the standard of care\* for mothers and infants of:

* Mothers: One NVP 200 mg tablet at onset of labor with continuation of HAART for four weeks postpartum

* Newborn: AZT+3TC+ NVP for 2 weeks, followed by AZT+3TC for 2 weeks:

* NVP syrup 2 mg/kg every 24 hours for seven days, followed by NVP syrup 4 mg/kg every 24 hours for seven days. Newborns less than 2500 g will be administered 2mg/kg NVP syrup at each intake

* AZT syrup 4 mg/ kg will be given every 12 hours for four weeks (preterm infants less than 30 weeks will be administered 2 mg/kg every 12 hours; preterm 30-35 weeks will receive 2 mg/kg every 12 hours for the first 2 weeks, increased to 3 mg/kg for the next 2 weeks).

* 3TC syrup 2 mg/kg every 12 hours for four weeks.

* The standard of care in Thailand is defined as:

* Maternal antiretroviral treatment: ZDV 300 mg, 3TC 150mg and LPV/r 400/100 twice a day starting as soon possible after 14 weeks of pregnancy + ZDV 300 mg every 3 hours during labor; this treatment may be continued, stopped or modified after delivery upon the recommendation of the internist.

* Newborn: ZDV 4 mg/kg every 12 hours for 4 weeks (ZDV dosing adjusted for premature infants).
