Fluarix/ FluLaval/ Fluarix Quadrivalent/ FluLaval Quadrivalent Vaccine Pregnancy Registry

GlaxoSmithKline507 enrolled

Overview

The purpose of this pregnancy registry study is to detect and describe abnormal pregnancy outcomes in women intentionally or unintentionally vaccinated with any of GlaxoSmithKline (GSK) Biologicals' seasonal Inactivated Influenza Vaccines (sIIVs): Fluarix, FluLaval, Fluarix Quadrivalent and FluLaval Quadrivalent.

This study is a transition of existing ongoing pregnancy registries for Fluarix/ FluLaval/Fluarix Quadrivalent/ FluLaval Quadrivalent into one post-authorization safety study (PASS). Pregnancy outcome data will be collected using questionnaires within 2 months of the estimated date of delivery (EDD) and approximately 6 months and 12 months after the EDD (for all live births) to ascertain the presence of birth defects not diagnosed before, from Q2 2014 to Q2 2019. The intent of the Registry is to prospectively collect data such as vaccination with GSK sIIVs during pregnancy or within 28 days preceding conception, potential confounding factors (such as exposure to other medications) and information related to the outcome of the pregnancy.

Medical Language ↔ Plain English

Inclusion Criteria: A subject will be included in the Registry if all of the following criteria are met: * Exposure to GSK sIIVs occurs during pregnancy or within 28 days preceding conception. * Subject is a US resident. * A HCP is identified (name, address and phone number). * Subject can be identified (by GSK or HCP). Data from registered subjects will be included in the analyses if the following criterion is met: • Pregnancy is ongoing and the outcome is unknown at the time of initial report. Exclusion Criteria: Data from registered subjects will not be included in the analyses if the following criterion is met: • Outcome of pregnancy is known at the time of initial report. Types of known outcomes include prenatal testing reports in which the results are abnormal or outside the reference range, indicating possible abnormality in the fetus.

Outcomes

Primary Outcomes

Number of Subjects Reported With Exposure and Outcomes, Stratified by Trimester of Exposure, in Pregnant Women Intentionally or Unintentionally Vaccinated With FluLaval During Pregnancy or Within 28 Days Preceding Conception

Exposures and outcomes were stratified by trimester of exposure: first (1st), second (2nd), third (3rd) and unknown trimester (Tr?) multiple exposures during a pregnancy were classified by the earliest trimester of exposure. The estimated gestational age at the time of vaccination was calculated based on the date of the last menstrual period. The 2nd trimester was considered to begin at week 14 and the 3rd trimester begun at week 28. The presence or absence of birth defects or other abnormalities was evaluated within each of the preceding outcome categories. Ongoing = subject still pregnant at the time of last contact. Note: The remaining pregnancies were ongoing at the time of last contact by the study staff. No further information on the outcome of these pregnancies was available as of 1st April 2020. Unknown = unknown outcome at the time of last contact.

Time frame: Data collected for a minimum of 5 years starting from June 1, 2014 till May 31, 2019: for each subject, data was collected within 2 months of estimated date of delivery (EDD) and follow-up 6 and 12 months after EDD (for all live births)

Number of Subjects Reported With Exposure and Outcomes, Stratified by Trimester of Exposure in Pregnant Women Intentionally or Unintentionally Vaccinated With FluLaval Quadrivalent During Pregnancy or Within 28 Days Preceding Conception

Exposure and outcomes were stratified by trimester of exposure: 1st, 2nd, 3rd and Tr?; multiple exposures during a pregnancy were classified by the earliest trimester of exposure. The estimated gestational age at the time of vaccination was calculated as described in the first outcome. Results were presented for the following categories: Ongoing, Live infants without congenital anomalies (Live infants without CA.); Spontaneous abortions with no apparent congenital anomalies (Sp. abortions with no ACA); Spontaneous abortions with congenital anomalies (Sp. abortions with CA). One subject had FluLaval Quadrivalent and Fluarix Quadrivalent listed as vaccine used. Therefore, same case was included in the respective table of each product in "Live infants without CA, 3rd Tr." category. Note: The remaining pregnancies were ongoing at the time of last contact by the study staff. No further information on the outcome of these pregnancies was available as of 1st April 2020.
