Management of Plaque Psoriasis With Biologic Therapies in Women of Child-Bearing Potential Consensus Paper

Abstract: Background Plaque psoriasis (PsO) is a chronic inflammatory disease that often presents at peak reproductive age in women of child-bearing potential (WOCBP). With the emergence of biologic therapies to treat PsO, guidance on disease management in WOCBP is needed to inform treatment decisions before, during, and after pregnancy. Objectives To develop a practical, up-to-date consensus document, based on available evidence and expert opinion where evidence was lacking, in order to guide both Canadian and internat… Show more

“…One hundred and ninety-three ixekizumab-exposed pregnancies were recorded in the ixekizumab integrated safety database, of which 99 were maternal exposure pregnancies (58 in clinical trials, 41 during post-marketing surveillance). The majority of maternal exposures occurred in the first trimester of pregnancy, a time period before active transfer of IgG across the placenta occurs (13). A review of this data did not identify any congenital malformations resulting from maternal exposure in clinical trials, while one event of congenital malformation was identified during post-marketing surveillance.…”

“…Human immunoglobin G (IgG), the predominant means of fetal immunity, crosses the placental barrier in a linear fashion as the pregnancy progresses, with the greatest transfer of IgG in the third trimester (13). Preferential transport occurs for IgG subclass 1 (IgG1), followed by IgG4 (13); therefore, as an IgG4, ixekizumab may be transmitted from the mother to the developing fetus (9). However, transplacental passage of ixekizumab is estimated to be low during the early phases of pregnancy, when Fc receptors have yet to develop on fetal trophoblasts (14).…”

“…To our knowledge, there are no studies conducted evaluating the safety of tildrakizumab during breast feeding. Due to tildrakizumab's large molecular structure, it is unlikely to be absorbed by the infant and is likely to be metabolized by the infant's gastrointestinal tract ( 132 , 133 ).…”

“…Despite the large number of publications to date, not all factors of the etiology and pathogenesis of psoriasis have been definitively elucidated, especially in women of reproductive age depending on hormonal status [6].…”
