A First-In-Human Study of ARO-033 in Adult Participants

Exclusion Criteria7

• Human immunodeficiency virus (HIV) infection, as shown by the presence of anti-HIV antibody (seropositive).
• Seropositive for hepatitis B virus (HBV) (hepatitis B surface antigen positive at screening) or hepatitis C virus (HCV) (HCV antibody positive with reflex confirmation using HCV RNA amplification at Screening). Cured HCV (positive antibody test without detectable HCV RNA) is permitted if HCV RNA has been negative for at least 2 years.
• Uncontrolled hypertension (resting systolic blood pressure ≥160 millimeters of mercury \[mmHg\] or diastolic blood pressure ≥95 mmHg, confirmed by repeat measurement, at Screening).
• Evidence of clinically significant immunocompromising condition (for example, primary immunodeficiency syndrome, aplastic anemia, known or suspected complement factor deficiency, or any other condition resulting in significantly impaired immune response as evidenced by recurrent infections), or recent/ongoing treatment with immunosuppressive agents.
• History of major surgery within 90 days of Screening.
• Use of an investigational agent or device within 30 days or 5 half-lives (whichever is longer) prior to dosing or current participation in an investigational study. Participants recently participating in studies involving investigational agents with prolonged therapeutic effect (such as ribonucleic acid interference \[RNAi\] therapeutics, cell or gene therapies) should be discussed with the Medical Monitor.
• Any medical condition or clinically significant laboratory abnormality at Screening that in the opinion of the Investigator should exclude the participant from participation, preclude safe and successful completion of the study, or confound study results.
