2. Known moderate or severe persistent asthma within the past 2 years, or uncontrolled asthma of any classification. Note that participants who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed to participate in the study.

7. Participants with active malignancy (not including basal cell carcinoma, non-melanoma skin cancer, cervical carcinoma in situ, localized prostate cancer treated with hormone therapy). Participants with history of other cancers should be free of disease for at least 2 years.

8. Participants with hypertriglyceridemia defined as >1000 mg/dL (CTCAE Grade 4).
