Our Differentiation
11 Simple subcutaneous injection To enable self-administration at home Tailored dosing To help alleviate symptoms across disease stage and severity Rapid & deep IgG reduction Strong correlation between deep IgG reduction and increased clinical efficacy Our differentiated value proposition: Three potentially unique attributes to address unmet patient needs
Deep IgG reduction: Consistent evidence across programs and indications that greater IgG reduction leads to greater efficacy1 Company Evidence of Greater IgG Reductions Translating to Clinical Benefit IT P Greater IgG reduction across arms greater platelet responses4 M G Patient-level scatter plot showed that greater IgG declines greater MG-ADL improvements2,3 TE D Greater IgG reduction across arms higher rates of anti-TSHR antibody reduction and greater clinical response rates 12 RA In those patients with greater IgG reduction correlation with greater autoAb reduction correlation with greater clinical response5 1. Many of the analyses above were post-hoc and not all were statistically significant. Cross trial and post-hoc analyses are inherently limited and are presented for hypothesis generating purposes only, nevertheless consistent and numerically positive increases in efficacy were observed as noted above; 2. argenx JP Morgan Healthcare Conference Presentation January 2021; 3.
