- Total Bilirubin (TBL) > 1.5 × institutional normal limits (subjects with known Gilbert syndrome who are excluded if TBL > 3.0 × institutional normal limits or direct bilirubin > 1.5 × institutional normal limits)
- Aspartate aminotransferase (AST) and Alanine transaminase (ALT) > 3.0 × institutional normal limits. Subjects with tumors in the liver AST and ALT > 5 × institutional normal limits.
- Albumin < 3.0 g/dL
- Creatinine > 1.5 × institutional normal limits
- Subject with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of first administration of study IP. Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease.
- Subject has an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, any form of substance abuse or psychiatric illness/social situations that would limit compliance with study visits or requirements, or a condition that could invalidate communication with the Investigator.
- Subject is known to be positive for human immunodeficiency virus, hepatitis B surface antigen, hepatitis B core immunoglobulin or immunoglobulin G (IgG) antibody, or hepatitis C (IgG or ribonucleic acid (RNA) test) indicating acute or chronic infection. HbsAg positive subject should further undergo hepatitis B virus (HBV) DNA titer detection. For HCV antibody positive subject, further HCV RNA testing is required. However, subject with the following conditions can be included in this study: Hepatitis B surface antigen (HBsAg) is negative; if HBcAb is positive, HBV-DNA (HBV deoxyribonucleic acid) < 200 IU/mL (or 1000 copies/mL).
- Subject has a history of moderate to severe ascites, clinically significant and/or rapidly accumulating ascites, bleeding esophageal varices, hepatic encephalopathy, or pericardial and/or pleural effusions related to liver insufficiency within 6 months of screening. Mild ascites that does not preclude safe IT injection of OH2 is allowed.
- Subject has a clinically significant abnormal electrocardiogram (ECG) at screening.
- Subject has symptomatic cardiovascular disease within the preceding 12 months unless cardiology consultation and clearance has been obtained for study participation, including but not limited to the following: significant coronary artery disease (e.g., requiring angioplasty or stenting), acute myocardial infarction or unstable angina pectoris < 3 months prior to screening, uncontrolled hypertension, clinically significant arrhythmia, or congestive heart failure (New York Heart Association grade ≥ 2).
- Subject who has a history of bleeding diathesis, are on anti-coagulation therapy, or have abnormal coagulation-fibrinolytic parameters (e.g., activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), and platelet count).
- Subject has medical conditions that predispose the subject to untoward medical risk in the event of volume loading (e.g., intravenous fluid bolus infusion), tachycardia, or hypotension during or following treatment with OH2.
- Subject has a known or suspected hypersensitivity to OH2 or any components of the formulation used, including prior adverse reaction to vaccinia (e.g., as smallpox vaccine).
- Subject has had previous exposure with OH2.
- Active herpetic skin lesions or prior complications of herpetic infection (e.g., herpetic keratitis or encephalitis).
- Requires intermittent or chronic systemic (intravenous or oral) treatment with an antiherpetic drug (e.g., acyclovir), other than intermittent topical use.
