Taltz® ▼ (ixekizumab): Graviditet, fertilitet och amning

Det finns otillräckligt med data från människor för att fastslå hur säkert ixekizumab är vid graviditet.

Short Answer Summary


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.


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. 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


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

There are limited safety data on the use of ixekizumab in pregnant women 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.6-9,11

Pregnancy Outcomes

Psoriasis and Psoriatic Arthritis Clinical Trials

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

Out 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 of the pregnancies. All but 4 women were known to have been exposed to ixekizumab during their first trimester of pregnancy.12

Information on these pregnancy cases is summarized in Table 1.

Axial Spondyloarthritis Trials

Two pregnancies were reported in female patients enrolled in axSpA trials (including AS/r-axSpA and nr-axSpA trials) 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
