Introduction: Vidofludimus calcium has shown anti-inflammatory effects in clinical trials of autoimmune diseases and recently demonstrated antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We performed a double-blind, randomized, placebo-controlled, phase 2 trial to evaluate the safety and efficacy of vidofludimus calcium in patients hospitalized for coronavirus disease 2019 (COVID-19) in Europe and the USA.
Methods: Patients aged 18 years or older who positive for COVID-19 were randomized (1:1) to receive placebo or 45 mg vidofludimus calcium for 14 days with both groups receiving standard-of-care treatment. The primary endpoint was the need for invasive ventilation after 28 days (ClinicalTrials.gov NCT04379271; EudraCT 2020-001264-28).
Results: Between June 12, 2020 and December 10, 2020, a total of 223 were randomized to receive either placebo (n = 112) or vidofludimus calcium (n = 111); three patients withdrew consent and were not treated. Eight (9%) patients in the placebo group and 12 (11%) patients in the vidofludimus calcium group needed invasive ventilation during the 28-day study period, which was lower than the assumed rate of 40%. Time to clinical improvement was shorter by approximately 1 day in the vidofludimus calcium group (15.0 days [90% CI 14.8-15.9]) compared to the placebo group (15.9 days [90% CI 14.9-19.9]). This effect was greatest in patients who initiated therapy within 9 days of symptom onset (3.8 days shorter in the vidofludimus calcium group). Higher trough concentrations of vidofludimus calcium were associated with quicker time to clinical recovery. The rate and timing of appearance of anti-SARS-CoV-2 antibodies were not different between groups. Serious adverse events occurred in 4 (4%) patients in the placebo group and 2 (2%) patients in the vidofludimus calcium group; treatment-emergent adverse events of increased severity related to COVID-19 occurred in 13 (12%) patients in the placebo group and 8 (7%) patients in the vidofludimus calcium group. Overall mortality was low (2%).
Conclusions: These findings support vidofludimus calcium being safe and well tolerated in patients with COVID-19.

Introduction: Vidofludimus calcium (VidoCa) is a dihydroorotate dehydrogenase (DHODH) inhibitor that demonstrated efficacy in immune-related diseases. This study assessed the safety and efficacy of VidoCa in patients with active ulcerative colitis (UC).
Methods: This placebo-controlled, phase 2 trial randomized adults with moderate-severe UC to receive once-daily VidoCa (10, 30, or 45 mg) or placebo for 10 weeks (induction); patients with symptomatic remission were re-randomized to VidoCa 10, 30 mg, or placebo once-daily for an additional 40 weeks (maintenance).

New strategies for the rapid development of broad-spectrum antiviral therapies are urgently required for emerging and re-emerging viruses like the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Host-directed antivirals that target universal cellular metabolic pathways necessary for viral replication present a promising approach with broad-spectrum activity and low potential for development of viral resistance. Dihydroorotate dehydrogenase (DHODH) was identified as one of those universal host factors essential for the replication of many clinically relevant human pathogenic viruses.

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.

Background: The article highlights upcoming potential treatments, which target different phases of inflammation and offer remyelinating strategies as well as direct and indirect neuroprotective and oligodendrocyte protective effects, providing a hopeful outlook for patients with primary and secondary progressive multiple sclerosis (PPMS and SPMS).
Objectives: The review aims to identify potential treatments and ongoing clinical trials for PPMS and SPMS, and compare their mechanisms of action, efficacy, and side effects with current treatments.
Methods: We reviewed ongoing clinical trials for PPMS and SPMS on the NIH website, as well as articles from PubMed, Embase, and clinicaltrails.

Hepatitis E virus (HEV) infection can cause severe complications and high mortality, particularly in pregnant women, organ transplant recipients, individuals with pre-existing liver disease and immunosuppressed patients. However, there are still unmet needs for treating chronic HEV infections. Herein, we screened a best-in-class drug repurposing library consisting of 262 drugs/compounds.
