Italics	For the most part, italics indicate an FDA comment such as: Additions and/or revisions underlined These italics usually appear at the beginning of the section. In some cases, italics may be an inherent part of the label, and will most often appear in the body of the section.
Underlines	Any text that is underlined indicates text that has been added or revised. There are exceptions where underlining occurs in a section subtitle or heading. This is the case when there is just one word underlined in the body of the text.

PCI/PI/MG	Patient Counseling Information (PLR format only) - summarizes the information that a health care provider should convey to a patient (or caregiver when applicable) when a counseling discussion is taking place (e.g., a physician prescribing a drug during an office visit, a nurse providing discharge instructions at a hospital, or a pharmacist conveying information at a pharmacy). Patient Information - FDA approved patient labeling. Medication Guide - paper handouts that come with many prescription medicines. The guides address issues that are specific to particular drugs and drug classes, and they contain FDA-approved information that can help patients avoid serious adverse events.

Only NDAs and CDER regulated BLAs are included in this database. ANDAs are not included.

Applications that remain active, even if the product has been discontinued, undergo safety-related labeling changes.

Adverse Reactions from Clinical Trials in Pediatric Subjects 12 Years of Age and Older

The safety of tralokinumab was assessed in a trial of 289 subjects 12 to 17 years of age with moderate-to-severe atopic dermatitis (ECZTRA 6). Of the 289 subjects, 195 were treated with ADBRY and 94 were treated with matching placebo. The safety profile of ADBRY in these subjects, assessed through the initial treatment period of 16 weeks and the long-term period of 52 weeks, was comparable to the safety profile from trials in adults with atopic dermatitis.

Safety through 268 weeks (ECZTEND)

ECZTEND was an open-label, multicenter, long-term extension trial that further assessed the safety of ADBRY for up to 5 years of treatment in adults and pediatric subjects 12 years of age and older with moderate-to-severe atopic dermatitis who had previously participated in ADBRY trials. The safety data in ECZTEND reflect exposure to ADBRY in 1672 subjects who received 300 mg of ADBRY every two weeks (Q2W), including 1422 exposed for at least 52 weeks, 1184 exposed for at least 104 weeks, 701 exposed for at least 156 weeks, and 33 exposed for at least 264 weeks.

The long-term safety profile was consistent with the safety profile observed up to week 16.

8 Use in Specific Populations

8.1 Pregnancy

Additions and/or revisions underlined:

Pregnancy Exposure Registry

There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADBRY during pregnancy. Healthcare providers are encouraged to register pregnant patients, or pregnant women may enroll themselves in the registry by calling 1-877-311-8972 or visiting https://mothertobaby.org/ongoing-study/adbry-tralokinumab/.

Risk Summary

There are limited data from the use of ADBRY in pregnant women to inform a drug-associated risk of adverse developmental outcomes. Monoclonal antibodies are actively transported across the placenta (see Clinical Considerations).

In an enhanced pre-and post-natal developmental study, no adverse developmental effects were observed in offspring born to pregnant monkeys after intravenous administration of tralokinumab-ldrm during organogenesis through parturition at doses up to 10 times the maximum recommended human dose (MRHD).

The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Clinical Considerations

Fetal/Neonatal Adverse Reactions

Transport of endogenous IgG antibodies across the placenta increases as pregnancy progresses and peaks during the third trimester. Therefore, ADBRY may be present in infants exposed in utero. The potential clinical impact of tralokinumab-ldrm exposure in infants exposed in utero should be considered.
