A Study of (LY3650150) Lebrikizumab to Assess the Safety and Efficacy of Adult and Adolescent Participants With Moderate-to-Severe Atopic Dermatitis and Skin of Color

Prior treatment

• Have uncontrolled asthma that
  • might require bursts of oral or systemic corticosteroids, or
  • required the following due to ≥1 exacerbations within 12 months before baseline
  • systemic (oral and/or parenteral) corticosteroid treatment, or
  • hospitalization for \>24 hours.
• Had prior treatment with dupilumab
• Had prior treatment with tralokinumab
• Treatment with topical agents (corticosteroids, calcineurin inhibitors, JAK inhibitors, or phosphodiesterase-4 inhibitors) within 2 weeks prior to baseline.
• Treatment with any of the following agents within 4 weeks prior to the baseline:
  • systemic immunosuppressive/immunomodulating drugs (for example, systemic corticosteroids, cyclosporine, mycophenolate mofetil, IFN-gamma, azathioprine, methotrexate, and other immunosuppressants);
  • small molecules (for example, Janus Kinase (JAK) inhibitors);
  • phototherapy and photochemotherapy for AD.

Other illness

• History of human immunodeficiency virus (HIV) infection or positive HIV serology at screening.
• Have a current infection or chronic infection with hepatitis B virus (HBV) at screening, that is, positive for hepatitis B surface antigen (HBsAg) and/or polymerase chain reaction positive for HBV DNA
• Have a current infection with hepatitis C virus (HCV) at screening, that is, positive for HCV RNA
• Have an uncontrolled chronic disease that might require multiple intermittent uses of oral corticosteroids at screening (as defined by the investigator).
• Have known liver cirrhosis and/or chronic hepatitis of any etiology.
• History of malignancy, including mycosis fungoides or cutaneous T-cell lymphoma, within 5 years before the screening, except completely treated in situ carcinoma of the cervix of completely treated and resolved non-metastatic squamous or basal cell carcinoma of the skin with no evidence of recurrence in the past 12 weeks.

• Participants must be ≥12 years of age inclusive, at the time of signing the informed consent/assent.
• Participants who are self-reported race other than White, including but not limited to persons who self-identify as Black or African American, American Indian or Alaska Native, Asian, Native Hawaiian, or Other Pacific Islander.
• Participants who are Fitzpatrick phototype IV-VI
• Participants who have chronic AD that has been present for ≥1 year before screening.
• Have EASI ≥16 at baseline
• Have IGA score ≥3 (Scale of 0 to 4) at baseline
• Have ≥10% body surface area (BSA) of AD involvement at baseline
• Have a history of inadequate response to treatment with topical medications; or determination that topical treatments are otherwise medically inadvisable.
• Adolescents body weight must be ≥40 kg at baseline.
• Are willing and able to comply with all clinic visits and study-related procedures and questionnaires.
• Contraceptive use - Male and/or female
  • Male participants are not required to use any contraception except in compliance with specific local government study requirements.
  • Female participants of child-bearing potential: must 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 study drug. Women of non-child-bearing potential (non-WOCBP) may participate without any contraception requirements.
