Vidofludimus calcium consistently reduced neurofilament light chain (NfL) levels in the Phase 2 CALLIPER trial, suggesting it may slow disease progression across all progressive MS subtypes, the company reported.
The drug also showed potential to reduce fatigue in MS patients by preventing Epstein-Barr virus (EBV) reactivation, which could contribute to reduced fatigue in MS patients.

Vidofludimus Calcium
Re: Vidofludimus Calcium
Vidofludimus calcium is also helpful in RRMS.
A double-blind, randomized, placebo-controlled phase 2 trial evaluating the selective dihydroorotate dehydrogenase inhibitor vidofludimus calcium in relapsing-remitting multiple sclerosis
Ann Clin Transl Neurol. 2022 Jul;9(7):977-987.
Objective: Inhibition of dihydroorotate dehydrogenase suppresses magnetic resonance imaging brain lesions and disease activity in multiple sclerosis but has limiting tolerability. We assessed the safety and efficacy of vidofludimus calcium, a novel, selective dihydroorotate dehydrogenase inhibitor, in patients with relapsing-remitting multiple sclerosis.
Methods: This double-blind, 24 weeks, placebo-controlled, phase 2 trial (EMPhASIS) enrolled patients 18-55 years with relapsing-remitting multiple sclerosis. Eligible patients were randomly assigned (1:1:1) to once-daily vidofludimus calcium (30 mg or 45 mg) or placebo. The primary endpoint was the cumulative number of combined unique active lesions to week 24 between vidofludimus calcium 45 mg and placebo (clinicalTrials.gov number NCT03846219; EudraCT 2018-001896-19).
Results: After 24 weeks, the mean cumulative number of combined unique active lesions was 6.4 (95% CI: 2.8-13.9) with placebo compared to 2.4 (95% CI: 1.1-4.9) with vidofludimus calcium 45 mg (rate ratio 0.38, 95% CI: 0.22-0.64; p = 0.0002); the rate ratio between vidofludimus calcium 30 mg and placebo was 0.30 (95% CI: 0.17-0.53; p < 0.0001). Treatment-emergent adverse events occurred in 30 (44%) of patients assigned placebo and 60 (43%) of patients assigned vidofludimus calcium. Serious adverse events occurred in one (1%) assigned placebo and two (1%) assigned vidofludimus calcium. No increased incidence of infectious, hepatic, or renal treatment-emergent adverse events or serious adverse events was observed.
Interpretation: Treatment with vidofludimus calcium led to a reduction in new magnetic resonance imaging lesions in patients with relapsing-remitting multiple sclerosis and was well tolerated with a favorable safety profile. Assessment in longer, larger trials is justified.

Re: Vidofludimus Calcium
Treats RRMS, will be the second PPMS drug, and first to be approved for non-relapsing SPMS.
It reduces EBV reactivation, there is less viral infection of any kind and covid, compared to placebo group.
The opposite of what we get from current DMTs!
The Nurr1 effect stops the brain inflammation from microglia and astrocytes, protecting neurons.
Great at lowering Nfl levels, reducing lesions, significantly slows progression.
Plus it heals the gut lining.

"Just got a phone call. Are you sitting down?
I’ve been on the CALLIPER trial for a MS med called IMU838 since summer of 2023. just got a call that the med reached all its endpoints with positive results. Early!
It was reported at ECTRIMS in Italy in April so I get to end the study now instead of December 2025! moving to open label which means I get the meds and follow up for eight years . FREE!
I am thrilled beyond belief! exciting way to start 59.

Safety and Dose-Response of Vidofludimus Calcium in Relapsing Multiple Sclerosis: Extended Results of a Placebo-Controlled Phase 2 Trial
Neurol Neuroimmunol Neuroinflamm. 2024 May;11(3):e200208.
Background and objectives: Vidofludimus calcium suppressed MRI disease activity compared with placebo in patients with relapsing-remitting multiple sclerosis (RRMS) in the first cohort of the phase 2 EMPhASIS study. Because 30 mg and 45 mg showed comparable activity on multiple end points, the study enrolled an additional low-dose cohort to further investigate a dose-response relationship.
Methods: In a randomized, placebo-controlled, phase 2 trial, patients with RRMS, aged 18-55 years, and with ≥2 relapses in the last 2 years or ≥1 relapse in the last year, and ≥1 gadolinium-enhancing brain lesion in the last 6 months. Patients were randomly assigned (1:1:1) vidofludimus calcium (30 or 45 mg) or placebo in cohort 1 and vidofludimus calcium (10 mg) or placebo (4:1) in cohort 2 for 24 weeks. The primary end point was the cumulative number of combined unique active (CUA) lesions at week 24. Secondary end points were clinical outcomes and safety.
Results: Across cohorts 1 and 2, 268 patients were randomized to placebo (n = 81), 10 mg (n = 47) vidofludimus calcium, 30 mg (n = 71) vidofludimus calcium, or 45 mg (n = 69) vidofludimus calcium. The mean cumulative CUA lesions over 24 weeks was 5.8 (95% CI 4.1-8.2) for placebo, 5.9 (95% CI 3.9-9.0) for 10 mg treatment group, 1.4 (95% CI 0.9-2.1) for 30 mg treatment group, and 1.7 (95% CI 1.1-2.5) for 45 mg treatment group. Serum neurofilament light chain decreased in a dose-dependent manner. The number of patients with confirmed disability worsening after 24 weeks was 3 (3.7%) patients receiving placebo and 3 (1.6%) patients receiving any dose of vidofludimus calcium. Treatment-emergent adverse events occurred in 35 (43%) placebo patients compared with 11 (23%) and 71 (37%) patients in the 10 mg or any dose of vidofludimus calcium groups, respectively. The incidence of liver enzyme elevations and infections were similar between placebo and any dose of vidofludimus calcium. No new safety signals were observed.
Discussion: Compared with placebo, vidofludimus calcium suppressed the development of new brain lesions with daily doses of 30 mg and 45 mg, but not 10 mg, establishing the lowest efficacious dose is 30 mg.
Classification of evidence: This study provides Class II evidence that among adults with active RRMS and ≥1 Gd+ brain lesion in the past 6 months, the cumulative number of active lesions decreased with vidofludimus calcium.
Trial registration information: ClinicalTrials.gov (NCT03846219) and EudraCT (2018-001896-19).

Immunic Presents Key Vidofludimus Calcium Data at the ACTRIMS Forum 2025, Highlighting Its Potential in Multiple Sclerosis
https://imux.com/immunic-presents-key-v ... sclerosis/
NEW YORK, February 26, 2025 – Immunic, Inc. (Nasdaq: IMUX), a biotechnology company developing a clinical pipeline of orally administered, small molecule therapies for chronic inflammatory and autoimmune diseases, today announced the presentation of data on its lead asset, nuclear receptor-related 1 (Nurr1) activator, vidofludimus calcium (IMU-838), in two poster presentations at the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2025, taking place from February 27 to March 1, in West Palm Beach, Florida.
“Having two poster presentations on vidofludimus calcium at the prestigious ACTRIMS Forum highlights the unique importance of our drug candidate and its promise as a potential new treatment option for multiple sclerosis (MS),” stated Daniel Vitt, Ph.D., Chief Executive Officer of Immunic. “For the first time, we analyzed the baseline characteristics of patients in subpopulations from our phase 2 CALLIPER trial in progressive multiple sclerosis (PMS), and compared to those from four major PMS trials. The goal of this analysis was to identify how the differences may impact comparability of trial outcomes, including our top-line data readout of the phase 2 CALLIPER trial, expected in April. The CALLIPER data is expected to provide valuable insights into the effects of vidofludimus calcium in a non-active PMS population. We believe any impact of vidofludimus calcium on 24-week confirmed disability worsening in this group would likely primarily reflect its influence on compartmentalized pathology within the central nervous system, expressed clinically as progression independent of relapse activity (PIRA).”
