Question
Victor Floc'h from BNP Paribas asked for an update on the ITP launch in Japan, specifically on physician feedback regarding its positioning against TPO-RAs, and if argenx could share its market share in that indication.
Answer
CEO Tim Van Hauwermeiren reported that the ITP launch in Japan is going well, with real-world data mirroring the clinical trial's ~50% response rate. He noted the drug is currently being used in last-line, highly refractory patients but is landing well due to its rapid action and safety profile. He expects it will gradually move up in the treatment paradigm over time, in line with the initial plan.
