Jun-Goo Kwak's questions to IMMUNIC (IMUX) leadership • Q3 2024
Question
Jun-Goo Kwak, on for Yasmeen Rahimi, asked for commentary on blinded safety and efficacy data from the CALLIPER trial and questioned which progressive MS subpopulation is most likely to show the largest treatment effect on disability worsening.
Answer
CEO Dr. Daniel Vitt stated he could not comment on blinded data but confirmed the CALLIPER study is progressing as expected. He elaborated on the three predefined subpopulations (active SPMS, non-active SPMS, and PPMS), suggesting that the non-active SPMS and PPMS populations are similar in their non-inflammatory disease progression and should have comparable placebo activity, while the smaller active SPMS subgroup (9% of patients) may have higher inflammatory activity.
