The purpose of the study is to assess systemic certolizumab pegol (CZP) exposure, the formation of anti-CZP antibodies and safety of CZP across the course of pregnancy in study participants with chronic inflammatory diseases.

The collection of blood samples for pharmacokinetics (PK) is considered interventional. Blood samples will be drawn at enrollment, predose every 4 weeks (Q4W), postdose every 8 weeks (Q8W) and postpartum predose and postdose. Study participants will be responsible for obtaining and administering commercially available approved dosing regimens of certolizumab pegol (CZP) as prescribed by each study participant's own physician.

Predose and Postdose Plasma Certolizumab Pegol (CZP) Concentrations in Women During Pregnancy, Relative to Postpartum
Predose and postdose plasma CZP concentrations in women during pregnancy, relative to postpartum, were measured. The trimesters were defined as follows: Trimester 1=up to 12 weeks and 6 days gestation, trimester 2=13-28 weeks and 6 days gestation, and trimester 3=any time at or after 29 weeks gestation.
Time frame: Predose and postdose CZP concentrations in Pregnancy trimester 1,2,3 (up to 40 weeks) and Postpartum (up to 13 weeks after delivery)
Number of Participants With Anti-certolizumab Pegol (CZP) Positive Antibodies Throughout the Study Period
Antibodies to CZP were evaluated in plasma samples collected from all participants throughout the study. Anti-CZP antibodies (ADAb) were measured using a three-tiered assay approach: screening, confirmatory and titration assay. Samples that were confirmed as positive in the screening and confirmatory assay were evaluated in a titration assay to quantify the ADAb level and were reported as titer (reciprocal dilution factor including minimum required dilution \[MRD\]). Sample values that were 'positive screen' and 'positive immunodepletion' were defined as ADAb positive. Once determined positive, a study participant's highest titer was used to categorize ("titer classification") the study participant as follows: Positive less than or equal to (=)32, Positive greater than (\>)32 - =128, Positive \>128 - =512, Positive \>512 - =1024, Positive \>1024 - =4096, and Positive \>4096.
Time frame: From Enrollment to Safety Follow-up (Duration of pregnancy (up to 40 weeks) + 18 weeks) (up to 58 weeks)
Percentage of Participants With Adverse Events From Time of Informed Consent (Screening) Through Safety Follow-up (SFU)
An adverse event (AE) was any untoward medical occurrence in a patient or clinical participant, temporally associated with the use of CZP, whether or not considered related to CZP.
Time frame: From Screening to Safety Follow-up (Duration of pregnancy (up to 40 weeks) + 18 weeks) (up to 58 weeks)

Number of Participants With Pregnancy Outcome
Pregnancy outcomes were collected via a written notification by the investigator and recorded in the Pregnancy Outcome Form. Pregnancies were determined to end in delivery-live birth, delivery-still birth, spontaneous abortion, therapeutic abortion, or missing data.
Time frame: From Enrollment to Delivery (Duration of pregnancy, up to 40 weeks)
