Study to Assess Maternal and Infant Outcomes Following Exposure to SPIKEVAX During Pregnancy

April 12, 2024 updated by: ModernaTX, Inc.

An Observational Study to Assess Maternal and Infant Outcomes Following Exposure to SPIKEVAX During Pregnancy

The primary objectives of this study are:

In infants of women exposed to SPIKEVAX during pregnancy, to assess:

  • If exposure to SPIKEVAX during pregnancy is associated with an increased birth prevalence of major congenital malformations (MCMs).
  • If exposure to SPIKEVAX during pregnancy is associated with an increased birth prevalence of adverse neonatal and infant outcomes, specifically neonatal encephalopathy, small for gestational age, respiratory distress in the newborn, and incidence of hospitalization due to infections including coronavirus disease 2019 (COVID-19).
  • In women exposed to SPIKEVAX during pregnancy, to assess whether exposure to SPIKEVAX is associated with an increased prevalence of hypertensive disorders [e.g., pre-eclampsia, eclampsia, and gestational hypertension] gestational diabetes, and post-partum hemorrhage; and
  • To assess whether exposure to SPIKEVAX during pregnancy is associated with an increased incidence of stillbirth, preterm birth, and medically attended spontaneous abortion.

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

  • Child
  • Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Study population includes women for whom an LMP can be successfully calculated based on a non-missing end of pregnancy (EOP), and who also meet the eligibility criteria to be included in the study analyses.

Description

Inclusion Criteria:

  • EOP within study period
  • Continuous enrollment in a health plan contributing to the HealthCare Integrated Research Database℠ (HIRD) database for at least 90 days prior to the estimated LMP.

Exclusion Criteria:

  • Exposure to any non-Moderna COVID-19 vaccines at any time prior to LMP and from LMP through the exposure ascertainment period for the outcome of interest. However, pregnant women exposed to other non-Moderna vaccines in addition to SPIKEVAX will be included in a sensitivity analysis.
  • Instances where the outcome of a pregnancy is not documented (e.g., a prenatal care claim is followed by no further documentation of pregnancy, termination, or delivery where the participant remains enrolled in the health plan) may also be observed. The number of these possibly exposed pregnancies will be tabulated and described; however, they will not be included in the descriptive or comparative analyses.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
SPIKEVAX Exposed Pregnancy
Cohort includes pregnant women who were vaccinated with SPIKEVAX from last menstrual period (LMP) through the exposure ascertainment period for the outcome of interest.
SPIKEVAX Distantly Exposed Pregnancy
Cohort includes pregnant women who were exposed to SPIKEVAX at least 60 days prior to LMP and not exposed to SPIKEVAX or any other COVID-19 vaccine from LMP through the exposure ascertainment period for the outcome of interest.
Unvaccinated During Pregnancy
Cohort includes pregnant women not exposed to SPIKEVAX or any other COVID-19 vaccine within 60 days prior to LMP through the exposure ascertainment period for the outcome of interest.
COVID-19 Infected During Pregnancy
Cohort includes pregnant women not exposed to SPIKEVAX or any other COVID-19 vaccine within 60 days prior to LMP through the exposure ascertainment period for the outcome of interest. These women also had at least one medically attended COVID-19 episode during the exposure ascertainment period outcome of interest.

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.
Outcome Measure
Measure Description
Time Frame
Number of MCMs
Time Frame: Up to approximately 3 years
Up to approximately 3 years
Number of Adverse Neonatal and Infant Outcomes
Time Frame: Up to approximately 3 years
Adverse neonatal and infant outcomes include neonatal encephalopathy, small for gestational age, respiratory distress in the newborn, or incidence of hospitalization due to infections including COVID-19.
Up to approximately 3 years
Number of Participants with Hypertensive Disorders
Time Frame: Up to approximately 3 years
Hypertensive disorders include pre-eclampsia, eclampsia, and gestational hypertension, gestational diabetes, or post-partum hemorrhage
Up to approximately 3 years
Number of Stillbirths, Preterm Births, and Medically Attended Spontaneous Abortions
Time Frame: Up to approximately 3 years
Up to approximately 3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
