Manos Mastorakis's questions to argenx SE (ARGX) leadership • Q4 2024
Question
Manos Mastorakis asked about the potential for competitors to improve upon efgartigimod's clinical outcomes in CIDP and whether complement inhibitors have a role to play in the disease.
Answer
CEO Tim Van Hauwermeiren asserted that argenx has set a very high bar with a 70% response rate in CIDP. He confirmed his belief that complement does have a role, which is why the company is advancing its C2 inhibitor, empasiprubart, in CIDP. This could potentially serve the 30% of non-responders, including patients with pathogenic IgM autoantibodies.
