Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a randomized, patient, investigator and sponsor blinded, placebo-controlled study in pregnant women with primary HCMV infection. The study has three periods: (I) screening (II) double-blinded placebo-controlled treatment and (III) post-delivery follow-up of women and neonates/infants. Pregnant women with confirmed primary HCMV infection will participate in periods I and II. Mothers and neonates/infants born to mothers enrolled in the study will participate in period III.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  1. Written informed consent must be obtained before any assessment is performed.
  2. Pregnant women ≥ 18 years of age with primary HCMV infection occurring between 6 and 24 weeks of gestation
  3. Ability to receive study drug within 6 weeks of the presumed onset of primary maternal infection.
  4. Able to communicate well with the investigator, to understand and comply with the requirements of the study.

Exclusion Criteria:

  1. Confirmed or suspected fetal HCMV infection, defined as positive HCMV DNA in amniotic fluid or fetal ultrasound abnormalities suggestive of fetal HCMV disease.
  2. Prior treatment with any of the following within 30 days prior to enrollment: ganciclovir, valganciclovir, foscarnet, cidofovir, acyclovir (>25 mg/kg/day IV), valacyclovir (>3 gm/day oral), famciclovir (>1500 mg/day oral), HCMV immune globulin, immune globulin (>500 mg/kg), or any other medication with anti-HCMV activity.
  3. Any surgical or medical condition (other than pregnancy) which might increase the risk for thrombotic events if the patient is given immune-globulins. These conditions include cryoglobulinemia, monoclonal gammopathies, and hypertriglyceridemia (fasting level >1000 mg/dL). The investigator should make this determination based on the patient's medical history and laboratory data.
  4. History of chronic hepatitis B, hepatitis C and human immunodeficiency virus (HIV) infection. Cured hepatitis C in not considered exclusionary.
  5. Patient request for medical interruption or termination of pregnancy before inclusion.
  6. Any surgical or medical condition which may jeopardize the patient or fetus in case of participation in the study. The investigator should make this determination in consideration of the patient's obstetrical history.
  7. Use of other investigational drugs at the time of enrollment, or within 5 half-lives of enrollment, or until the expected pharmacodynamic effect has returned to baseline, whichever is longer; or longer if required by local regulations.
  8. History of hypersensitivity to any of the study treatments or excipients or to drugs of similar chemical classes.
  9. Body weight > 100 kilograms.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
