Brief Summary

The main aim of the study is to evaluate the effect of LAD603 in adult participants with severe to very severe alopecia areata (AA). The study will also evaluate the safety, pharmacokinetics (PK), immunogenicity and pharmacodynamic (PD) biomarkers of LAD603.

Inclusion Criteria: * Participant is a male or female between 18 and 65 years old at the time of signing the informed consent. * Severe to very severe AA criteria: 1. Greater than or equal to (\>=) 50% hair loss of the scalp as measured by SALT without evidence of terminal hair regrowth within 6 months at both the Screening and Baseline (Day 1) visits. 2. Current episode of hair loss lasting at least 6 months and not exceeding 7 years. * Participants who are WOCBP or male must agree to the requirements for the avoidance of pregnancy and exposure of the participant's partner to LAD603 during the study, Exclusion Criteria: AA, Skin Specific, and Other Inflammatory Diseases * Participants have other types of alopecia (including but not limited to traction, scarring alopecia). * Participants with "diffuse" type AA. * Currently has an active form of other inflammatory skin disease(s) or evidence of skin condition (e.g., psoriasis, seborrheic dermatitis, lupus) at the time of the Screening or Baseline (Day 1) visits that is expected to interfere with the assessment of alopecia areata severity.
