Eligibility
Key inclusion criteria
- Participant must be 18 years of age, inclusive, or older at the time
of signing the informed consent.

- Participated in an amlitelimab clinical trial for moderate to severe AD and received
study treatment, adequately completed the assessments required for the treatment
period.

- Have reached the rollover timepoint to LTS17367 at the last visit of the
treatment period of their parent study SFY17915

- Participants in DRI17366 must only be enrolled from 1 of the following 3 groups:

Investigator Global Assessment (IGA) = 2.

- The second group: participants entering LTS17367 between Week 28 and Week 52

instance of < EASI 50 during the second study period and where rescue
therapy is no longer permitted.

of invasive opportunistic infections or helminthic infections despite infection
resolution or otherwise recurrent infections of abnormal frequency or prolonged
duration

- History of solid organ or stem cell transplant

- Any malignancies or history of malignancies prior to Baseline (except for non-melanoma
skin cancer that has been excised and completely cured for more than 5 years prior to
Baseline)

- Participants positive for human immunodeficiency virus; participants with any of the
following results at Screening (Visit 1) or at any point during the parent study:

presence of anti-HBs Ab with positive HBV DNA PCR test; positive HCVAb confirmed by
positive HCV RNA

- History (within last 2 years prior to Baseline) of prescription drug or substance
abuse, including alcohol, considered significant by the Investigator

- Participants with active TB, latent TB, a history of incompletely treated TB,
suspected extrapulmonary TB infection, non-TB mycobacterial infection, or who are at
high risk of contracting TB (such as close contact with individuals with active or
latent TB) or received Bacillus Calmette-Guérin (BCG)-vaccination within 12 weeks
prior to screening

- Participants with an intermediate or a positive IGRA test are excluded from the study
unless all of the following conditions are met:

1. Have a history of prior documented completed chemoprophylaxis for latent TB
infection (with a treatment regimen as per local guidelines), OR treated for
active TB infection

2. Have been in written form approved for participation in the present trial by a TB
specialist who ruled out latent or active TB infection or other mycobacterial
infection in the participant

3. For whom review and approval from Sponsor have been granted are eligible

- Severe concomitant illness that would in the Investigator's opinion inhibit the
patient's participation in the study, including for example, but not limited to,
hypertension, renal disease, neurological conditions, heart failure and pulmonary
disease

- Skin co-morbidity that would adversely affect the ability to undertake AD assessments

- Any medical or psychiatric condition which, in the opinion of the Investigator may
present an unreasonable risk to the study patient as a result of his/her participation
in this clinical study, may make patient's participation unreliable, or may interfere
with study assessments

- In the Investigator's opinion, medical conditions related to prior AD medications that
have not healed/fully recovered for more than 2 weeks before screening visit,
including, but not limited to, conjunctivitis, keratitis, eosinophilic conditions,
arthralgia, herpes zoster, thrombosis

Summary
Brief summary
This is a single group, Phase 2, long-term extension study for treatment. The purpose of this
study is to characterize the safety and efficacy of amlitelimab in treated adult participants
with moderate to severe AD who have previously been enrolled in an amlitelimab clinical
trial. Visits during the on-treatment period will be at Week 0, 1, 2, 4 and every 4 weeks
(Q4W) thereafter. If remote visits are considered appropriate for participants instead of
clinic visits at the timepoints indicated in the schedule of activities (SoA)
participants/caregivers/legally authorized representatives (LAR) are allowed to perform
participant-injections at home according to the schedule of dosing. This decision is at the
discretion of the investigator.
