What to Expect as a Participant

This is an observational study. You will not receive an experimental treatment; researchers will collect data based on your existing condition or standard treatment.

This trial targets 900 participants in total. It began in 2022-12-08 with a primary completion date of 2034-11-30.

Brief Summary

The goal of this observational study is to learn about exposure to tralokinumab during pregnancy, as well as atopic dermatitis (AD) during pregnancy. The main question the study aims to answer is whether pregnant people who have been exposed to tralokinumab during pregnancy experience any differences in pregnancy and infant outcomes compared to women with atopic dermatitis who have not been exposed to tralokinumab during pregnancy. Participants are not required to take tralokinumab during the study. Participants will be asked to: * Complete 1-3 phone interviews during pregnancy and 1-2 phone interviews after delivery * Release medical records for pregnancy and for their child * Complete an online survey about their baby's development at 4 months and 12 months of age * May be asked to have a study doctor examine their child All information is collected remotely, and no visits to the study site are required.

Eligibility Criteria

Inclusion Criteria: Eligibility for the cohort study includes the following: 1. Currently pregnant at the time of enrollment 2. Reside in the US or Canada at the time of enrollment 3. Verbal informed consent to participate OTIS Pregnancy Registry 4. Current diagnosis of AD at the time of enrollment Cohort 1: Tralokinumab-Exposed Cohort 1. Diagnosed with AD 2. Exposure to tralokinumab for any number of days, at any dose, and at any time during pregnancy or within 16 weeks prior to the date of conception 3. Agree to the conditions and requirements of the study including the interview schedule, dysmorphology exam (for the first 80 pregnancies resulting in live born infants), developmental screening, and release of medical records Cohort 2: AD Comparator I- Phototherapy or Systemic Treatment 1. Diagnosed with AD 2. Exposed to phototherapy and/or systemic therapy for the treatment of AD for any number of days, at any dose, and at any time within 5 half-lives prior to the date of conception or during pregnancy 3. Agree to the conditions and requirements of the study including the interview schedule, dysmorphology exam (for the first 80 pregnancies resulting in live born infants), developmental screening, and release of medical records Cohort 3: AD Comparator II - With or Without Treatment 1. Diagnosed with AD 2. May or may not have received treatment for AD, but have not been exposed to any dose of phototherapy or systemic therapy for the treatment of AD within 5 half-lives prior to the estimated date of conception or any time during pregnancy. 3. Agree to the conditions and requirements of the study including the interview schedule, dysmorphology exam (for the first 80 pregnancies resulting in live born infants), developmental screening, and release of medical records Exclusion Criteria: Pregnant women meeting any of the following criteria will not be included in the cohort study: Cohort 1: Tralokinumab-Exposed Cohort 1. Women who have enrolled in the tralokinumab cohort study with a previous pregnancy 2. Exposure to any dose of methotrexate or mycophenolate mofetil within 5 half-lives prior to the estimated date of conception or anytime during pregnancy 3. Retrospective enrollment after the outcome of pregnancy is known (i.e., the pregnancy has ended prior to enrollment) 4. Results of a diagnostic test are positive for a major structural birth defect prior to enrollment. However, women who have had any normal or abnormal prenatal screening or diagnostic test prior to enrollment are eligible as long as the test result does not indicate a major structural defect Cohort 2: AD Therapy Comparator I- Phototherapy or Systemic Treatment 1. Pregnant women who have enrolled in the tralokinumab cohort study with a previous pregnancy 2. Exposure to any dose of tralokinumab, methotrexate or mycophenolate mofetil within 5 half-lives prior to the estimated date of conception or anytime during pregnancy. 3. Retrospective enrollment after the outcome of pregnancy is known (i.e., the pregnancy has ended prior to enrollment) 4. Results of a diagnostic test are positive for a major structural defect prior to enrollment. However, women who have had any normal or abnormal prenatal screening or diagnostic test prior to enrollment are eligible as long as the test result does not indicate a major structural defect Cohort 3: AD Therapy Comparator II - With or Without Treatment 1. Pregnant women who have enrolled in the tralokinumab cohort study with a previous pregnancy 2. Exposure to any dose of tralokinumab, methotrexate or mycophenolate mofetil within 5 half-lives prior to the estimated date of conception or anytime during pregnancy 3. Exposure to any dose of phototherapy and/or systemic therapy for the treatment of AD within 5 half-lives prior to the estimated date of conception or during pregnancy 4. Retrospective enrollment after the outcome of pregnancy is known (i.e., the pregnancy has ended prior to enrollment) 5. Results of a diagnostic test are positive for a major structural defect prior to enrollment. However, women who have had any normal or abnormal prenatal screening or diagnostic test prior to enrollment are eligible as long as the test result does not indicate a major structural defect Case-Series: Tralokinumab-Exposed Case Series Pregnancies with tralokinumab exposure that do not meet the exposed cohort (Cohort 1) criteria will be excluded from the cohort, but will be included in the Exposure Series. Women who are eligible for enrollment in the Exposure Series include, but are not limited to the following: exposed to tralokinumab during pregnancy for an indication other than AD, women who enrolled with a previous pregnancy in the cohort, and retrospective reports of a tralokinumab-exposed pregnancy after the outcome of pregnancy is known. With informed consent, data will be collected from those enrolled in the Exposure Series from maternal interviews and medical record review using the same protocol as the cohort study to the extent possible.
