The purpose of this study is to compare the efficacy of two doses of nevirapine (NVP) given only to the infants or lopinavir/ritonavir (LPV/r) from 28 weeks gestation with single dose (SD) NVP given to the mothers plus two doses to the infants, in addition to zidovudine (ZDV) prophylaxis (from 28 weeks' gestation and for one week of ZDV in neonates) for the prevention of mother-to-child transmission of HIV-1.

- Definitive HIV infection in infants as assessed by positive HIV DNA PCR on two peripheral blood samples [ Time Frame: At birth, 7-10 days, 1, 2, 4 and 6 months of age ] [ Designated as safety issue: No ]
- Safety for mothers and children of two NVP doses in neonates with and without maternal single dose NVP at onset of labor or LPV/r from 28 weeks gestation. [ Time Frame: From randomization during pregnancy until 24 months after delivery ] [ Designated as safety issue: Yes ]

Detailed Description:
Multicenter, placebo-controlled, double blind, clinical trial where non immunocompromised women receiving the ZDV prophylaxis regimen from 28 weeks gestation, as recommended in Thailand, will be randomized to one of two arms:
Arm 1: NVP-NVP:
- In women, one NVP 200 mg tablet at onset of labor+;
- In neonates, NVP oral suspension 6 mg in the delivery room immediately after birth plus a second dose between 48 and 72 hours+++
Arm 2: PL-NVP:
- In women, one placebo tablet at onset of labor++;
- In neonates, NVP oral suspension 6 mg in the delivery room immediately after birth plus a second dose between 48 and 72 hours+++
Arm 3: LPV/r:
In women, LPV/r 400/100 mg bid from 28 weeks' gestation until delivery
- women in Arm 1 will also receive 7-day ZDV 300mg bid plus 3TC 150mg bid from delivery. ++women in Arm 2 will also receive 7-day (ZDV+3TC) Placebo from delivery. +++If the new born weight less than 2500 g, nevirapine will be administered 2 mg./1 kg (As per Thai Guideline).
All infants will receive ZDV for at least one week. Follow-up of women and infants is carried out on an outpatient basis except for delivery and the first three days after delivery. Mothers and infants are followed-up for 24 months after delivery.
Note: The study was stopped and data unblinded upon DSMB recommendations in September 2010 because of changes in Thai PMTCT guidelines recommending use of HAART in all HIV infected pregnant women regardless of their CD4 count. At the time of unblinding 435 pregnant women had been enrolled and follow-up of these women and their children is continuing.

Inclusion Criteria:
Women are eligible for the study if they

- antiretroviral naïve except for exposure to ZDV prophylaxis PMTCT;
- CD4 count above 250 cells/mm3 (within 4 months prior to randomization)
- agreement not to breastfeed;
- consent to participate and to be followed for the duration of the study;
- and the following laboratory values within 14 days prior to randomization:
- hemoglobin > 8.5 mg/dl;
- absolute neutrophil count > 750 cells/mm3;
- platelets > 50,000 cells/mm3;
- SGPT ≤ 5 times upper limit of normal;
- serum creatinine ≤ 1.5 times upper limit of normal (women with a serum creatinine > 1.5 times upper limit of normal must have a measured eight-hour urine creatinine clearance > 70 ml/min).
Exclusion criteria:
- Evidence of pre-existing fetal anomalies incompatible with life;
