NCT00486863

Brief Summary

The purpose of the study is to understand whether the drug praziquantel (PZQ) is safe for the mother and developing baby when the mother has schistosomiasis (a type of worm) infection, and whether the drug may improve the mother's and baby's health. The usual practice is to wait until after a mother has finished breast feeding before giving the medicine. Approximately 375 infected pregnant women, ages 18 and over, in endemic villages in Leyte, The Philippines will participate. Study volunteers 12-16 weeks pregnant will be given PZQ or an inactive pill (placebo) and stay in the hospital overnight. Small blood samples will be collected before and after the medication is taken. Three stool and urine samples will be taken during a total of 7 study visits. An ultrasound image (picture or outline of the unborn baby) will be performed. When the baby is born, a small blood sample will be taken. Mother and baby will be followed for up to 8 months before the baby is born and 1 month after.

Outcome Measures

Primary Outcomes (1)

  • Mean Newborn Birth Weight

    Birth weight was collected for live infants at the time of delivery by a trained midwife, or within 24 hours of delivery for participants who chose to deliver at home with a helot, a birth attendant without formal training.

    Within 24 hours of delivery.

Secondary Outcomes (19)

  • Number of Participants Whose Pregnancy Resulted in a Live Birth

    At delivery

  • Mean Change in Maternal Hemoglobin From 14 to 32 Weeks Gestation

    14 weeks and 32 weeks gestation

  • Median Change in Maternal Transferrin Receptor:Ferritin Ratio From 14 to 32 Weeks Gestation

    14 weeks and 32 weeks gestation

  • Median Maternal Hepcidin at 32 Weeks Gestation

    32 weeks gestation

  • Mean Change in Maternal Weight From 14 to 32 Weeks Gestation

    14 and 32 weeks gestation

  • +14 more secondary outcomes

Study Arms (2)

Control

PLACEBO COMPARATOR

Placebo at 12-16 weeks gestation.

Other: Placebo

Praziquantel

EXPERIMENTAL

Praziquantel at 12-16 weeks gestation.

Drug: Praziquantel

Interventions

60 mg/kg administered orally given in split dose (30/mg/kg each) separated by 3 hours; over-encapsulated in gelatin capsules. Two capsule sizes will be made which will be differentiated by color; these will contain 300 mg or 150 mg to allow for best dosing by weight.

Praziquantel
PlaceboOTHER

Made with the same color coded gelatin capsules with the inert compound dextrose.

Eligibility Criteria

Age18 Years - 99 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • For screening:
  • Female, age 18 or over.
  • Present to a study midwife with suspected pregnancy.
  • Live in a study village.
  • For the main study:
  • Infected with S. japonicum.
  • Pregnancy as determined by urine pregnancy test.
  • Age 18 or older.
  • Participant is otherwise healthy as determined by history, physical exam, ultrasound and laboratory assessment.
  • Pregnancy between 12-16 weeks gestation.
  • Ability to provide informed consent to participate.

You may not qualify if:

  • Presence of significant disease/illness that is either acute or chronic. This will be defined by history, physical examination, ultrasound and laboratory assessment. In particular:
  • History of seizures or other neurologic disorder, chronic medical problem determined by history or physical examination, e.g. active hepatitis, tuberculosis, heart disease.
  • Women with myoma on ultrasound that are sub-mucosal or women with myoma that is in any location and greater than 5 cm in size.
  • Women with congenital anomalies of the reproductive tract that would be expected to cause decreased fetal weight or greatly increase the risk of prematurity such as duplicate uterus, uterine septum.
  • For less clear cases, the researchers will define significant illness as one that significantly alters a woman's ability to perform activities of daily living, causes symptoms at least two days per week, or necessitates regular use of medication. In the case of acute medical conditions such as urinary tract infection, pneumonia, febrile illness, enrollment may be postponed until the illness is successfully treated (not currently on any medication for the illness) or the illness self resolves if this occurs before 16 weeks gestation.
  • Presence of cysts in the eye suggestive of neurocysticercosis.
  • Regular use of a medication for a chronic medical condition.
  • History of severe allergic reaction (anaphylaxis, facial swelling, or difficulty breathing) or seizure with praziquantel administration.
  • Fetus has congenital anomaly determined by 12-16 week ultrasound or is determined to be nonviable (e.g. blighted ovum).
  • Twin or higher order pregnancy.
  • Woman has been enrolled into this study for a previous pregnancy.
  • Inability to comprehend study procedures and provide informed consent due to limited cognitive abilities or other, or refuses to provide informed consent.
