Reassurance for women taking certolizumab during pregnancy

 

Key clinical point: Certolizumab use during pregnancy does not appear to increase the risk of congenital malformations.

Major finding: The incidence of fetal death and congenital malformations in certolizumab-exposed pregnancies is similar to that in the general population.

Study details: A prospective and retrospective analysis of data from 528 certolizumab-exposed pregnancies.

Disclosures: The study was funded by UCB Pharma. One author was a contractor for UCB Pharma, and three were employees of, UCB Pharma. Six authors declared grants, consulting fees, and other remuneration from pharmaceutical companies, including UCB Pharma.

FROM ARTHRITIS & RHEUMATOLOGY

The use of certolizumab pegol during pregnancy does not appear to be associated with an increased risk of fetal death or congenital malformations, according to results of a new study.

Megan E.B. Clowse, MD, of Duke University Medical Center, Durham, N.C., and her coauthors reported on a prospective and retrospective analysis of data from 528 pregnancies – including 10 twin pregnancies – in which the mother was exposed to the anti–tumor necrosis factor (anti-TNF) drug certolizumab during pregnancy.

There were 459 (85.3%) live births, 47 (8.7%) miscarriages, 27 (5%) elective abortions, and five (0.9%) stillbirths, figures that are similar to those seen in the general population. Among the singleton births, 11.7% were low birth weight, which the authors noted was slightly higher than the frequency observed in the general population but was in line with previous reports with TNF inhibitors.

Two cases of neonatal death were reported. One occurred in one member of a female twin pair, born at 25 weeks, who succumbed to brain damage and pneumoperitoneum. The other was also in female twins, born at 27 weeks, in which one of the pair was born with a heart defect and died during surgery for an unspecified infection of the intestines, the authors reported in Arthritis & Rheumatology.

The study noted eight (1.7%) reports of congenital malformations in the infants born alive, including accessory auricle, polydactyly, hydronephrosis, cerebral ventricle dilatation, and congenital heart disease.

Four cases were in infants whose mothers had rheumatoid arthritis, one in an infant whose mother had ankylosing spondylitis, and three in infants whose mothers had Crohn’s disease (CD).

In five cases, the women were exposed to certolizumab at least in the first trimester, in four they were exposed at least in the second trimester, and in five cases, the women were exposed at least during the third trimester of pregnancy.
