Inclusion
- Male or female aged 18 to 49 years, inclusive.
- Responsive to inhaled endotoxin; defined as a reduction of 10% or greater in forced expiratory volume in 1 second (FEV1) following inhalation of 20 µg equivalent of Clinical Center Reference Endotoxin.
- Have a body weight greater than 65 kg and a body mass index (BMI) below 30.
- Have normal lung function, defined as:
- Forced vital capacity (FVC) \> 80% of that predicted value;
- FEV1 \> 80% of that predicted value; and

Exclusion
- Have any condition, including findings in the medical history or in the pre-study assessments, which, in the opinion of the investigator, constitute a risk or contraindication for the participation of the subject to the study, or that could interfere with the study objectives, conduct, or evaluation including, but not limited to:
- Any clinically significant abnormality in the results of pre-study safety laboratory tests.
- A positive test for drugs of abuse or alcohol breath test.
- Positive results from serum tests for Hepatitis B surface antigen (not due to vaccination), Hepatitis C, or Human Immunodeficiency Virus.
- History or presence of lung disease including asthma, chronic obstructive lung disease, or emphysema.
- History of atopy, including hay fever or atopic dermatitis.
- History or presence of liver disease.
- Hyperthyroidism, hypoglycemia, hyperglycemia, or diabetes mellitus.
- History or presence of autoimmune disorders including myositis, hepatitis, idiopathic thrombocytopenic purpura, psoriasis, rheumatoid arthritis, interstitial nephritis, Sjögren's syndrome, thyroiditis, or systemic lupus erythaematosus.
- Occurrence of any acute infection within the last 2 weeks before dosing.
- Presence or history of any severe allergic reactions; or history of allergy to any medications that may be used or prescribed in the course of this study (eg, albuterol, prednisolone, acetaminophen, aspirin or other non-steroidal anti-inflammatory agents, or adalimumab).
- History or presence of drug or alcohol abuse. (i;e. average daily intake of 3 units or a maximum weekly intake of greater than 21 units (1 unit equals 340 milliliters \[ml\] of beer, 115 ml of wine, or 43 ml of spirits).
- History or active manifestation of a serious psychiatric illness including depression, suicidal ideation, or psychosis.
- Positive test for latent tuberculosis.
- Loss or donation of blood within 12 weeks prior to entry into the study, or plasma donation within 1 week prior to entry into the study.
- Use of any prescription drugs within 2 weeks or over-the-counter medication, including herbal supplements or multivitamins, within 1 week before drug administration without prior approval from the investigator.
- Use of any medication that may impact the results of any of the challenges, interfere with any other medications potentially used in the study, including steroids, beta blockers, or non-steroidal anti-inflammatory agents.
- Previous participation in this study, or administration of any investigational drug within 12 weeks prior to entry into the study.
- Exposure to endotoxin, within 12 weeks of signing the informed consent for this study.
