The subject has abnormal laboratory values at Screening that suggest a clinically significant underlying disease, or the subject has the following laboratory abnormalities: alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) >1.5 times the upper limit of normal unless otherwise agreed to by the Sponsor and Principal Investigator.

In addition to the general criteria above, AD patients in Part B must meet the following inclusion criteria to enter the study:

1. The patient has a diagnosis of AD (according to the criteria established by Hanifin et al, 2001 and Rajka et al, 1989).
2. The EASI score is =15 at Screening.
3. The score on the Investigator's Global Assessment is =3 at Screening.
4. The score on the SCORing Atopic Dermatitis instrument is =20 at Screening.
5. The total body surface area affected by AD is =10% as assessed by the EASI at Screening.
6. The patient has an inadequate response to topical medications, or topical treatment is medically inadvisable.

In addition to the general criteria above, AD patients in Part B must not meet any of the following exclusion criteria:

1. The patient has another dermatologic condition that might confound a diagnosis of AD or a treatment assessment.
2. The patient has a history of anaphylaxis following biologic therapy.
3. The patient has a history of clinically significant infections within 4 weeks prior to Day -1.
4. The patient has a diagnosis of helminthic parasitic infection within 6 months prior to Screening.
5. The patient has received any marketed or investigational biologic agent within 5 half-lives prior to Screening.
6. The patient has received treatment with immunosuppressive or immunomodulatory drugs without adequate washout, or has received phototherapy for AD within 4 weeks prior to Day 1. For drugs, an adequate washout period is 5 half-lives (e.g., 10 weeks for dupilumab).
7. The patient has initiated treatment with topical corticosteroids (TCS) or topical calcineurin inhibitors within 1 week prior to Day -1. If rescue medications are deemed warranted by the PI class IV TCS may be used as rescue medication after Day -1 (see Table 13).
8. The patient has initiated treatment with prescription moisturizers or moisturizers containing additives such as ceramide, hyaluronic acid, urea, or filaggrin degradation products during the Screening period (patients may continue to use stable doses of such moisturizers if initiated before the Screening visit, but should not change to a different product during the study).
9. The patient plans to use any other prohibited medication or undergo any prohibited procedure during the study. Oral antibiotics are permitted. Bleach baths are not permitted.
10. The patient has received any investigational compound within 30 days or 5 half-lives (whichever is greater) days prior to Day 1.
11. The subject has a risk of suicide per the Columbia-Suicide Severity Rating Scale (a score of 4 or above on ideation or any suicidal behavior) or according to the Investigator's clinical judgment, has made a suicide attempt in the previous 6 months, or has a history of deliberate self-harm in the past 6 months. A subject with a lower score may be enrolled in the study.
12. The patient has any clinically relevant abnormal finding.

Summary
Brief summary
This randomized, double-blind, single center, placebo-controlled, phase 1 single ascending dose (SAD)/multiple ascending dose (MAD) study is designed to assess the safety, tolerability, PK, activity, immunogenicity, and PD of BSI-045B. Approximately 68 subjects will be enrolled. Subjects in this study include 56 healthy volunteers (HVs) and 12 patients with AD.

This study is divided into 3 parts:

1. Part A: Evaluate the safety, tolerability, PK, immunogenicity, and PD of single ascending doses of BSI-045B administered as a subcutaneous (SC) injection of 120, 240, 480, and 720 mg to HVs
2. Part B: Evaluate the safety, tolerability, PK, activity (as measured by the Eczema Area and Severity Index \[EASI\] score), immunogenicity, and PD of a single dose of BSI-045B administered as a SC injection of 480 mg to patients with AD
3. Part C: Evaluate the safety, tolerability, PK, immunogenicity, and PD of multiple ascending doses of BSI-045B administered as five (5) SC injections of 240, 480, and 600 mg every 7 days (Q7D) to HVs
