Figure 1 Plasma hFIX levels in rhesus macaques. Vector was administrated on day 0. Normal; >30% of normal. Mild; >5–30% of normal. Moderate; ≥1–5% of normal. Severe; <1% of normal. Normal hFIX level is ~5,000 ng/ml. Molecular Therapy 2012 20, 1863-1870DOI: (10.1038/mt.2012.143) Copyright © 2012 The American Society of Gene & Cell Therapy Terms and Conditions
Figure 2 Serum ALT and AST levels in rhesus macaques. Normal range for ALT is 5–61 U/l. Normal range for AST is 12–63 U/l. Grade 1 (mild) = 1.1–2.5× upper limit of normal (ULN). Grade 2 (moderate) = 2.6–5.0× ULN. Grade 3 (severe) = 5.1–10× ULN. Grade 4 (potentially life-threatening) >10× ULN. ALT, alanine transaminase; AST, aspartate transaminase.
