Short Summary

Pregnancy

There is a limited amount of data from the use of ixekizumab in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to

  • pregnancy,
  • embryonic/foetal development,
  • parturition or
  • post-natal development.

As a precautionary measure, it is preferable to avoid the use of ixekizumab during pregnancy.1

Women of childbearing potential should use an effective method of contraception during treatment and for at least 10 weeks after treatment.1

Ixekizumab is a humanized IgG4 monoclonal antibody.2

  • Human IgG is known to cross the placental barrier.3,4
  • Therefore, ixekizumab may be transmitted from the mother to the developing fetus.

Lactation

It is not known whether ixekizumab is excreted in human milk or absorbed systemically after ingestion. However, ixekizumab is excreted at low levels in the milk of cynomolgus monkeys.1

A decision should be made whether to discontinue breast-feeding or to discontinue ixekizumab taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman.1

Fertility

The effect of ixekizumab on human fertility has not been evaluated. Animal studies do not indicate direct or indirect harmful effects with respect to fertility.1

Information from the Clinical Trials

Limited safety data are available on the use of ixekizumab in pregnant women who are exposed to ixekizumab.5

Pregnant and breastfeeding women were excluded from ixekizumab clinical trials. Women who became pregnant were discontinued from the trials.6-11

All women agreed to use a reliable method of birth control during ixekizumab clinical trials and for at least 12 weeks following the last dose of ixekizumab.6-9,11

Pregnancy Outcomes

Psoriasis and Psoriatic Arthritis Clinical Trials

In the case of pregnancy in a study patient, her discontinuation from study treatment was required per protocol.12

Of 2499 female patients exposed to ixekizumab in 16 PsO and PsA clinical trials through September 20, 2018, 50 cases of pregnancy were identified and the outcome is known for 44 cases of pregnancy. All but 4 women were known to have been exposed to ixekizumab during their first trimester of pregnancy.12

Axial Spondyloarthritis Trials

Across all female patients enrolled in the axSpA trials (including AS/r-axSpA and nr-axSpA trials), 2 pregnancies were reported as of April 1, 2019. These 2 patients were enrolled in the COAST-X trial in patients with nr-axSpA. Both pregnancies led to term deliveries.13
