Immunic presented four posters of new clinical, biomarker, and preclinical data for vidofludimus calcium (IMU-838) at the joint ACTRIMS-ECTRIMS meeting in Toronto. Phase 2 CALLIPER open-label extension data showed durable disability-outcome trends with continued treatment, and post-hoc analyses using novel bidirectional endpoints showed patients 2.47x more likely to achieve confirmed disability improvement (p=0.037). Preclinical work suggested Nurr1-dependent neuroprotection beyond DHODH inhibition. Importantly, the CALLIPER primary endpoint (percent brain volume change) was not met -- these are exploratory and post-hoc findings.
