Brief summary: The purpose of this study is to assess whether tralokinumab can be a helpful treatment for alopecia areata. This is a randomized, double-blind, placebo-controlled pilot study of a total of 30 subjects with moderate to severe alopecia areata involving 30-100% of the scalp. Expected is 50% of these subjects to have concomitant alopecia areata (AA) and atopic dermatitis (AD). Subjects with AA alone (15 subjects) will be randomized (2:1) to either receive tralokinumab or placebo via subcutaneous injection every 2 weeks for 24 weeks. Subjects with concomitant alopecia areata and atopic dermatitis (15 subjects) will be randomized separately in a 2:1 ratio to receive tralokinumab or placebo via subcutaneous injection every 2 weeks for 24 weeks.

Detailed description: The purpose of this study is to assess whether tralokinumab can be a helpful treatment for alopecia areata.

This is a randomized, double-blind, placebo-controlled pilot study of a total of 30 subjects with moderate to severe alopecia areata involving 30-100% of the scalp. The researchers expect 50% of these subjects to have concomitant alopecia areata (AA) and atopic dermatitis (AD).

The researchers' experience in AD12-14, and past experience in psoriasis15, 16 showed that biomarker studies in skin tissues are critical to the understanding of key pathogenic pathways that are upregulated in each disease and how well they are suppressed with effective treatment. These mechanistic studies coupled with clinical trials are key in the disease to shed light on important disease mechanisms, and to explain which molecules are suppressed by each therapeutic target. Data shows that IL-13 is significantly upregulated in both AD and AA lesions compared to nonlesional skin. It is very important to associate the clinical responses with suppression of this cytokine and related molecules as well as other pathway cytokines in skin tissues. Both the whole genomic profiling and individual molecular and cellular markers are very important in order to understand how well anti-IL-13 will change/suppress AA-associated pathways and compare with those that will be suppressed in AD.

Since this study is designed to gain basic knowledge rather than to yield information directly related to patient care, the results are not entered in the participants' medical records. If, at a later date, correlations of in-vitro tests and the patients' clinical situation suggest that the results do bear on the patients' health, an amended protocol will be submitted to the IRB so that results can be made available to the medical record.

Eligibility criteria: Inclusion Criteria:

If a subject declines to participate in the pharmacogenetic research, there will be no consequence or loss of benefit to the subject. The subject will not be excluded from the other aspects of the study described in the protocol, as long as they consent to participate in the study.
* Subject is judged to be in good general health as determined by the principal investigator based upon the results of medical history, laboratory profile, and physical examination performed at Screening.
* Subjects may be naïve to treatment or unresponsive to intralesional steroids or other treatments for alopecia areata.

Exclusion Criteria:

* History of male or female pattern hair loss Ludwig stage III or Hamilton \> stage V.
* Subjects in whom the diagnosis of alopecia areata is in question.
* Any disorder, including but not limited to, cardiovascular, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, haematological, psychiatric, or major physical impairment that is not stable in the opinion of the Investigator and could:

  1. Affect the safety of the subject throughout the study
  2. Influence the findings of the studies or their interpretations
  3. Impede the subject's ability to complete the entire duration of study
* Known history of allergy or reaction to any component of the IP formulation.
* History of anaphylaxis following any biologic therapy.
