Chouchana (Controls unexposed, disease free), 2025 France
2018 - 2023
All singleton pregnancies lasting ≥22 weeks of gestation (WG), linked with a childbirth stay allowing assessment of pregnancy outcomes, and carried out between January 2018 and December 2023. Females with cystic fibrosis (fwCF) and at least one prescription of CFTR modulators, specifically elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) filled from one month in the preconception period until delivery. unexposed, disease free
Females not having cystic fibrosis (CF).
148 / 3879601 Among 148 pregnancies, 136 were exposed during first trimester and treatment was maintained through whole pregnancy in 119 fwCF. (> 90%=> considered as at least T1).

Jain, 2025 USA
2010 - 2021
All female individuals with Cystic Fibrosis (fwCF) who reported conception from January 1, 2010, to June 30, 2021, and treated in one of the 11 participating US adult CF centers. Female individuals with Cystic Fibrosis (fwCF) treated with CF transmembrane conductance regulator (CFTR) modulator during any trimester of pregnancy. unexposed, sick
Female individuals with Cystic Fibrosis (fwCF) not treated with CF transmembrane conductance regulator (CFTR) modulator during pregnancy.
114 / 193 Results reported here => Sum of highly effective modulator therapy (HEMT) including ivacaftor or elexacaftor/tezacaftor/ivacaftor; and other modulators including lumacaftor/ivacaftor and tezacaftor/ivacaftor.
Salvatore, 2026 Italia
2016 - 2023
Women with cystic fibrosis (WwCF) with at least one pregnancy over the 2016–2023 study period, registered in the from the Italian CF Registry (ICFR). Women with cystic fibrosis (WwCF) on CF transmembrane conductance regulator protein modulators (CFTRm) therapy during pregnancy. unexposed, sick
Women with cystic fibrosis (WwCF) not on CF transmembrane conductance regulator protein modulators (CFTRm) during pregnancy.
46 / 98 In all exposed women: 42 continued throughout pregnancy and 4 suspended during the first trimester => > 90% Throughout pregnancy. 55 women were on CFTR modulator therapy before pregnancy: 45 ETI, 7 Ivacaftor, 2 Lumacaftor/Ivacaftor, 1 not specified.
