Zofran Attorneys Provide Birth Defects Research Overview

Attorneys handling Zofran lawsuits have expanded their Zofran lawsuit website to include a summary of international birth defects research from the Onder Law Firm at www.ZofranBirthDefectsLawsuitCenter.com.

Tuesday, March 17, 2015 - New Zofran safety information for pregnant women is available from attorneys handling Zofran lawsuits. Several studies of the effects of Zofranw on fetal development have been conducted worldwide. The findings from this research are summarized for the general public at the firm‘s website. Attorneys handling Zofran lawsuits for birth defect allegations offer free, no-obligation case review to anyone who would like to learn more about filing a claim.

While GlaxoSmithKline has not independently conducted any clinical studies on the safety of Zofran for pregnant women and their fetuses, the drug maker was allegedly aware of the risk of birth defects, according to a Zofran lawsuit filed in Massachusetts last month.* Sources cited include animal studies, adverse event reports, and epidemiological studies, based on court documents.

Four animal studies dating back to the 1980s established the fact that Zofran administered to a pregnant animal such as a rabbit or rat will cross the placental barrier to reach her unborn fetus, according to court documents.** The lawsuit alleges that these studies should have led the drug maker to further investigate the dangers of Zofran for pregnant women, according to court documents.

GlaxoSmithKline has allegedly received over 200 adverse event reports related to birth defects from Zofran, according to the lawsuit. Birth defects most frequently cited include congenital heart defects, cleft palate and cleft lip, intrauterine death, stillbirth, and a range of "severe malformations", according to court documents. The lawsuit alleges that the number reported to GSK is only a fraction of the number of birth defects that have occurred, according to court documents.

Three epidemiological studies comprise the clinical research available on Zofran and the risk of Zofran birth defects, according to the lawsuit.*** Two of these utilized Danish birth records to examine the incidence to birth defects in babies exposed to Zofran in utero. While their specific conclusions were distinct, together these two studies allegedly indicate an increased risk of cardiovascular birth defects and congenital heart defects for fetuses who were exposed to Zofran during the first trimester of development, according to court documents.

In conclusion, the Zofran lawsuit alleges, "Since at least 1992, GSK has had mounting evidence showing that Zofran presents an unreasonable risk of harm to babies who are exposed to the drug during pregnancy."
