A Study for GSK3862995B in Healthy Participants and Participants With Chronic Obstructive Pulmonary Disease

Korábbi kezelés

• A history of recurrent infections, or treatment of a chronic infection within 3 months prior to the first dose of study drug, including both serious local infection (for example, cellulitis, abscess) or systemic infection (for example, pneumonia, tuberculosis, hepatitis B, shingles).

Más betegség

• Participant has a past or current medical condition(s) or disease(s) that is/are not well controlled and, which in the judgement of the Investigator, may affect participant safety or affect study endpoints.
• Significant allergies to humanized monoclonal antibodies.
• Clinically significant multiple or severe drug allergies, intolerance to topical corticosteroids, or severe post-treatment hypersensitivity reactions (including, but not limited to, erythema multiforme major, linear immunoglobulin A (IgA) dermatosis, toxic epidermal necrolysis, and exfoliative dermatitis).
• Lymphoma, leukemia, or any malignancy within the past 5 years except for basal cell or squamous epithelial carcinomas of the skin that have been resected with no evidence of metastatic disease for 3 years.
• Breast cancer within the past 10 years
• Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).

Laborértékek

• Alanine transaminase (ALT) >1x upper limit of normal (ULN)
• Total bilirubin >1.5xULN (isolated total bilirubin >1.5xULN is acceptable if total bilirubin is fractionated and direct bilirubin less than (<) 35%).
