The authors commented that, despite increasing evidence of the safety of TNF inhibitors during pregnancy – recent systematic reviews and meta-analyses have found no link to adverse outcomes with anti-TNF exposure during the first trimester – patients and physicians still have had concerns about their use.
“This analysis of prospective pregnancy reports from the UCB Pharma safety database represents the largest published cohort of pregnant women exposed to an anti-TNF for the management of chronic inflammatory diseases,” the authors wrote. “It addresses the need for new and detailed studies on the impact of drug exposure during pregnancy and supports the conclusion that CZP exposure in utero does not appear to increase the risk of major congenital malformations or fetal loss.”
However, they acknowledged the lack of an untreated control group and said this meant a formal statistical analysis was not possible. They also noted that outcomes data were not available for about one-third of the entire cohort of 1,137 women whose pregnancies were exposed to certolizumab.
“However, these data are reassuring for women of childbearing age affected by chronic inflammatory diseases who need an anti-TNF to control their condition and wish to become or are pregnant during CZP treatment,” they wrote.
