602 Pregnancies Examined by the Non-Profit Organization of Teratology Information Specialists

LA JOLLA, CA –A new study conducted by birth defects experts from the Organization of Teratology Information Specialists (OTIS) suggests adalimumab use in pregnancy was not associated with an increased risk for adverse outcomes examined, such as major structural birth defects, spontaneous abortion and preterm delivery. The findings were published today in the Public Library of Science (PLOS) One Journal.

The prospective research study conducted by OTIS examined 602 pregnancies that occurred between 2004 – 2016 in women across the U.S. and Canada. Researchers enrolled pregnant women into the observational cohort study who had or had not taken adalimumab for their autoimmune disease, as well as generally healthy pregnant women for comparison. OTIS is the scientific non-profit society that provides the no-cost MotherToBaby information service and enrolls women through the MotherToBaby Pregnancy Studies Research Center at the University of California San Diego. Financial support for the adalimumab study was provided by AbbVie.

“Many women hoping to start a family rely on adalimumab to control symptoms related to crippling autoimmune diseases such as rheumatoid arthritis or Crohn’s Disease,” said lead study author Christina Chambers, PhD, MPH, OTIS/MotherToBaby president and professor of pediatrics at the University of California, San Diego. “The fact that this study showed no increased risk in adverse birth outcomes with the use of adalimumab in pregnancy is important since not a lot of research was previously available on this particular medication.”

The study also found that regardless of whether they took adalimumab or not, pregnant women with rheumatoid arthritis or Crohn’s Disease were at an increased risk of preterm birth (delivery before 37 weeks of pregnancy).

“Studies on medication use in general are lacking when it comes to understanding their effects on pregnancy, making it difficult for pregnant women and their healthcare providers to make informed decisions,” said Dr. Chambers. “We are proud to add valuable information to the literature and encourage more pregnant women to consider volunteering for critical observational studies.”
