As with all oligonucleotides, there is a potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay and therefore comparison of antibody incidence is misleading. In placebo-controlled and open-label clinical studies, 1 of 111 patients with acute hepatic porphyria (AHP;0.9%) developed treatment-emergent anti-drug antibodies (ADA) during treatment. No clinically significant differences in the clinical efficacy, safety, pharmacokinetic, or pharmacodynamic were observed in the patients who tested positive for ADA.

Uncommon (0.1% to 1%): Treatment emergent anti-drug antibodies


Very common (10% or more): Fatigue (10%)
