Reducing the Burden of Malaria in HIV-Infected Pregnant Women and Their HIV-Exposed Children (PROMOTE-BC2)

Overview

This is a double-blinded, randomized controlled trial of 200 HIV-infected pregnant women living in Tororo, Uganda, an area of high malaria transmission. HIV-infected pregnant women between 12 and 28 weeks gestation will be randomized to receive enhanced malaria chemoprevention with monthly dihydroartemisinin-piperaquine (DP) versus monthly DP placebo. Their HIV-exposed children will receive the same prevention regimen from 2 to 24 months of age to which the mothers were randomized. All women will receive daily trimethoprim-sulfamethoxazole (TS) throughout the study per Uganda Ministry of Health guidelines. Children will also receive daily TS from 6 weeks to 24 months of age. TS will be considered a study drug only in infants and children beginning 6 weeks after cessation of breastfeeding and upon exclusion of HIV infection. Women and their children will be followed for 36 months after delivery. In a subset of the study population, the investigators will conduct an intensive pharmacokinetic study that will evaluate pharmacokinetic exposure of DP and EFV. The investigators will also measure HIV-related outcomes among the women enrolled in the study. The investigators will test the hypothesis that for HIV-infected mothers and HIV-exposed infants, that enhanced versus standard malaria chemoprevention in HIV-infected pregnant women and their children will reduce the incidence of malaria among children from 0 to 24 months of age and improve the development of naturally acquired antimalarial immunity.

Detailed Description

Pregnant women will be scheduled to be seen in the study clinic every 4 weeks during their pregnancy. Women will be seen at 1 week, 6 weeks, and 3 months postpartum and every 3 months thereafter. In addition, pregnant women will be instructed to come to the study clinic for all their medical care and avoid the use of any outside medications. Women will be provided all routine HIV care at the clinic according to Uganda MOH guidelines. All women will have ARVs and TS dispensed at the study clinic. Counseling on breastfeeding and infant feeding will be provided per Uganda MOH guidelines. HIV care and breastfeeding and infant feeding recommendations may be changed to reflect the most recent standard of care per MOH guidelines. Children will be scheduled to be seen in the clinic every 4 weeks and parents /guardians of children will be instructed to bring their child to the study clinic for all medical care and avoid the use of any outside medications. The study clinic will remain open 7 days a week from 8 a.m. to 5 p.m. Each time a study participant is seen in the clinic a standardized history and physical exam will be performed. Patients who are febrile (tympanic temperature > 3 8.0˚C) or report history of fever in the past 24 hours will have blood obtained by finger prick for a thick blood smear. If the thick blood smear is positive, the patient will be diagnosed with malaria. If the thick blood smear is negative, the patient will be managed by study physicians for a non-malarial febrile illness. If the patient is afebrile and does not report a recent fever, a thick blood smear will not be obtained, except when following routine testing schedules. Routine assessments will be done in the clinic every 4 weeks for both pregnant women and children. Pregnant women and children will receive standards of care as designated in the Uganda MOH guidelines. Children will have care for HIV-exposed children according to MOH guidelines, with the exception that TS will be continued until 2 years of life. Routine care in children will use Integrated Management of Childhood Illness (IMCI) guidelines. During routine assessments subjects will be asked about visits to outside health facilities and the use of any medications outside the study protocol. Standardized assessment of adherence will also be done for study drugs administered at home and Insecticide Treated Net use. A routine history and physical exam will be performed using a standardized clinical assessment form. Blood will be collected by finger prick for thick smear, collection of plasma for PK studies, and filter paper samples. Phlebotomy for routine laboratory tests (CBC and ALT) to monitor for potential adverse events from study medications and for immunology studies will be performed every 8 weeks in pregnant women. Non malaria screening will also include stool ova and parasite examination, circulating filarial antigens (by ICT card for Wucheria), and blood smear for microfilaremia (including Mansonella perstans) using Knott's technique. For pregnant women, study drugs will be administered at the time of each routine visit.

Interventions

  • Drug: Monthly dihydroartemisinin-piperaquine (DP) + daily trimethoprim/sulfamethoxazole (TS)
  • Drug: Monthly placebo + daily trimethoprim/sulfamethoxazole (TS)

Arms, Groups and Cohorts

  • Active Comparator: Daily TS + Monthly DP pregnancy
    • Women will be given DP (3 full strength tabs, 40 mg/320 mg, given once a day for 3 consecutive days) every 4 weeks during pregnancy. During pregancy, TS will be given to women at a dose of 960mg once daily.
  • Placebo Comparator: Daily TS + DP Placebo pregnancy
    • Women will be given DP placebo (3 tabs, given once a day for 3 consecutive days) every 4 weeks during pregnancy. During pregnancy, TS will be given to women at a dose of 960mg once daily.

Clinical Trial Outcome Measures

Primary Measures

  • Number of Participants With Placental Malaria
    • Time Frame: at delivery estimated to be within 10 to 30 weeks of study entry
    • The primary outcome will be the prevalence of placental malaria based on placental histopathology and dichotomized into any evidence of placental infection (parasites or pigment) vs. no evidence of placental infection.
  • Incidence of Malaria, Pregnant Women
    • Time Frame: Time at risk will begin following administration of first dose of study drug to delivery
    • The primary outcome will be the incidence of malaria, defined as the number of incident episodes per time at risk. Incident cases will include all treatments for malaria not proceeded by another treatment in the previous 14 days.

Secondary Measures

  • Maternal Parasitemia at Delivery by Microscopy and LAMP
    • Time Frame: At delivery
    • Proportion of women with parasitemia detected by microscopy or LAMP at delivery
  • Placental Parasitemia (Number of Women With Placental Blood Samples Positive for Malaria by Microscopy or PCR)
    • Time Frame: At delivery
    • Proportion of placental blood samples positive for malaria by microscopy or PCR
  • Number of Monthly Routine Visits With Positive Blood Samples for Parasites
    • Time Frame: Following administration of first dose of study drug to delivery
    • Proportion of monthly routine blood samples positive by LAMP for parasites
  • Composite Adverse Birth Outcome (Proportion With Low Birth Weight (<2500 gm), Spontaneous Abortion (<28 Weeks), Stillbirth (Fetal Demise ≥28 Weeks), Congenital Anomaly, or Preterm Delivery (<37 Weeks)
    • Time Frame: At delivery
    • Proportion with low birth weight (<2500 gm), spontaneous abortion (<28 weeks), stillbirth (fetal demise ≥28 weeks), congenital anomaly, or preterm delivery (<37 weeks)

    • Time Frame: Following administration of first dose of study drugs to delivery
