Long-term Safety and Efficacy Study of Lebrikizumab (LY3650150) in Participants With Moderate-to-Severe Atopic Dermatitis (ADjoin)

Study Overview
=================
Brief Summary
-----------------
This 110-week study is designed to assess the long-term safety and efficacy of lebrikizumab for moderate-to-severe atopic dermatitis.

Detailed Description
-----------------
Participants who have completed participation in a Dermira- or Lilly-sponsored lebrikizumab study (parent study), DRM06-AD04, DRM06-AD05, DRM06-AD06, DRM06-AD17 or DRM06- AD18, will be offered the opportunity to enroll in this study. Participants may either be blinded or not blinded, depending on their parent study assignment. This study will also be open to an additional approximately 100 participants in the United States (addendum) who have not completed participation in a Dermira- or Lilly-sponsored lebrikizumab study. Treatment will not be blinded.

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria for participants coming from a parent study: Participants must meet all the following criteria to be eligible for this study: Received treatment in a lebrikizumab study, NCT04146363, NCT04178967, NCT04250337, NCT04250350 and have adequately completed the study treatments and last patient visit of the parent trial. For women of childbearing potential: agree to remain abstinent (refrain from heterosexual intercourse) or use a highly effective contraceptive method during the treatment period and for at least 18 weeks after the last dose of lebrikizumab or placebo. Exclusion Criteria for participants coming from a parent study: Participants meeting any of the criteria below will not be included in this study: Participants who, during their participation in the parent trial, developed a serious adverse event (SAE) deemed related to lebrikizumab, which in the opinion of the investigator or of the medical monitor could indicate that continued treatment with lebrikizumab may present an unreasonable risk for the participant. * Participants who, during their participation in the parent trial, developed an AE that was deemed related to lebrikizumab and led to study treatment discontinuation, which in the opinion of the investigator or of the medical monitor could indicate that continued treatment with lebrikizumab may present an unreasonable risk for the participant. * Conditions in the previous parent study consistent with protocol-defined criteria for permanent study drug discontinuation, if deemed related to lebrikizumab or led to investigator - or sponsor-initiated withdrawal of participant from the study (e.g., non-compliance, inability to complete study assessments, etc.). * Pregnant or breastfeeding women, or women planning to become pregnant or breastfeed during the study. Open-Label Addendum Inclusion Criteria: Participants must meet all the following criteria to be eligible for this study addendum: Male or female adults and adolescents (≥12 to <18 years of age and weighing ≥40 kilogram (kg). Chronic AD (according to American Academy of Dermatology Consensus Criteria) that has been present for ≥1 year before screening. Eczema Area and Severity Index (EASI) score ≥16 at baseline. Investigator Global Assessment (IGA) score ≥3 (scale of 0 to 4) at baseline. ≥10% body surface area (BSA) of AD involvement at baseline. History of inadequate response to treatment with topical medications; or determination that topical treatments are otherwise medically inadvisable. Open-Label Addendum Exclusion Criteria: Participants meeting any of the criteria below will be excluded from this study addendum: Have received a dose of lebrikizumab in any prior lebrikizumab clinical study. History of anaphylaxis Treatment with topical prescription moisturizers, corticosteroids, calcineurin inhibitors, or phosphodiesterase-4 inhibitors such as crisaborole within 1 week prior to baseline. Treatment with any of the following agents within 4 weeks prior to the baseline. Immunosuppressive/immunomodulating drugs (e.g., systemic corticosteroids, cyclosporine, mycophenolate-mofetil, IFN-γ, Janus kinase inhibitors, azathioprine, methotrexate, etc.) Phototherapy and photochemotherapy (PUVA) for AD. Treatment with the following prior to baseline: Immunosuppressive/immunomodulating drugs (e.g., systemic corticosteroids, cyclosporine, mycophenolate-mofetil, IFN-γ, Janus kinase inhibitors, azathioprine, methotrexate, etc.) Phototherapy and photochemotherapy (PUVA) for AD. Treatment with the following prior to baseline: An investigational drug within 8 weeks or within 5 half-lives (if known), whichever is longer. B Cell-depleting biologics, including rituximab, within 6 months. Other Biologics within 5 half-lives (if known) or 8 weeks, whichever is longer. Regular use (more than 2 uses per week) of a tanning booth/parlor within 4 weeks of baseline. Treatment with a live (attenuated) vaccine within 12 weeks of the baseline or planned during the study. Uncontrolled chronic disease that might require multiple intermittent uses of oral corticosteroids, e.g., co-morbid severe uncontrolled asthma, (as defined by the investigator). Pregnant or breastfeeding women, or women planning to become pregnant or breastfeed during the study. Evidence of active acute or chronic hepatitis History of human immunodeficiency virus (HIV) infection or positive HIV serology at screening. History of malignancy, including mycosis fungoides, within 5 years before screening, except completely treated in situ carcinoma of the cervix, completely treated and resolved non-metastatic squamous or basal cell carcinoma of the skin with no evidence of recurrence in the past 12 weeks.
