All Clinical Trials for DIROXIMEL FUMARATE

Trial ID Title Status Sponsor Phase Start Date Summary
NCT03498131 ↗ Melatonin in Patients With Multiple Sclerosis (MS). Active, not recruiting Providence Health & Services Early Phase 1 2018-05-09 To date, there are no published data on the role of melatonin supplementation or the appropriate dose for patients with multiple sclerosis. Because of the potential benefits of melatonin, this pilot study will be an exploratory investigation to evaluate the effect of supplementing melatonin in subjects with multiple sclerosis who are taking an oral disease modifying therapy (DMT) for 6 months or longer. It is our intent that the results of this study will support the rationale and be a prelude to a larger trial which can focus on clinical efficacy of melatonin therapy outcomes.
NCT05083923 ↗ A Study of Diroximel Fumarate (DRF) in Adult Participants From the Asia-Pacific Region With Relapsing Forms of Multiple Sclerosis (RMS) Not yet recruiting Biogen Phase 3 2021-11-19 The primary objectives of this study are to determine the safety and tolerability of DRF administered for up to 24 weeks in adult East Asian participants with RMS (Part 1) and to determine the safety and tolerability of DRF administered for up to 48 weeks in adult East Asian participants with RMS (Part 2). The secondary objective of this study is to evaluate the pharmacokinetic(s) (PK) of DRF metabolites (monomethyl fumarate [MMF] and 2-hydroxyethyl succinimide [HES]) following multiple doses of DRF in a subset of adult East Asian participants with RMS (Part 1).
NCT05127564 ↗ A Study to Evaluate the Pharmacokinetics, Safety, and Tolerability of Diroximel Fumarate (DRF) in Chinese and Caucasian Adult Healthy Participants Not yet recruiting Biogen Phase 1 2022-01-31 The primary objective is to evaluate the primary pharmacokinetic (PK) parameters of DRF active metabolite monomethyl fumarate (MMF) following multiple doses of DRF in Chinese and Caucasian adult healthy participants. The secondary objectives are to evaluate the secondary PK parameters of DRF active metabolite MMF following multiple doses of DRF in Chinese and Caucasian adult healthy participants, to evaluate the PK of DRF inactive major metabolite 2-hydroxyethyl succinimide (HES) following multiple doses of DRF in Chinese and Caucasian adult healthy participants and to evaluate the safety and tolerability of multiple oral doses of DRF in Chinese and Caucasian adult healthy participants.
NCT05181215 ↗ Bioequivalence Study of Bafiertam 190 mg and Vumerity® 462 mg Delayed-Release Capsules in Fasting Healthy Subjects Completed Banner Life Sciences LLC Phase 1 2021-05-14 A single-dose, randomized, open-label, two-way crossover, two-period, two-sequence, two-treatment, single-center, bioequivalence study of Bafiertam and Vumerity.
NCT05798520 ↗ A Study to Evaluate Safety and Efficacy of BIIB091 in Participants With Relapsing Forms of Multiple Sclerosis Not yet recruiting Biogen Phase 2 2023-06-02 The primary objectives are to investigate the safety and tolerability of BIIB091 monotherapy in participants with relapsing multiple sclerosis (RMS) (Part 1), and to evaluate the effects of BIIB091 combination therapy with Diroximel Fumarate (DRF) compared with the DRF monotherapy arm, on the key Magnetic Resonance Imaging (MRI) measure of active Central Nervous System (CNS) inflammation (Part 2). The secondary objectives are to evaluate the effects of BIIB091 monotherapy on the MRI measures of active CNS inflammation, to evaluate the effects of BIIB091 combination therapy with DRF compared with the DRF monotherapy arm on additional MRI measures of active CNS inflammation, to investigate the safety and tolerability of BIIB091 combination therapy with DRF in participants with RMS.
NCT06319339 ↗ Impact of Nrf2 Activation on Macrovascular, Microvascular & Leg Function & Walking Capacity in Peripheral Artery Disease RECRUITING University of Nebraska EARLY_PHASE1 2024-11-14 Peripheral artery disease (PAD) is associated with elevated oxidative stress, and oxidative stress has been implicated as the cause of reduced endothelial reactivity in individuals with PAD. Endothelial function is important because the endothelium contributes to the dilation of arteries during exercise, thereby implicating impaired endothelial function as a mechanism contributing to exacerbated exercise-induced ischemia. Therefore, the purpose of this study is to test the hypothesis that acute exogenous diroximel fumarate (Vumerity) intake will improve antioxidant capacity, thereby reducing oxidative stress and improving vascular function and walking capacity in those with PAD. During this study, participants will be administered diroximel fumarate or a placebo, and the acute effects of diroximel fumarate on vascular function and walking capacity will be assessed. Vascular function and walking capacity will be assessed with flow-mediated dilation, arterial stiffness, head-up tilt test, blood biomarkers, near-infrared spectroscopy, and a treadmill test. There will be a follow-up visit to assess blood work after diroximel fumarate.
NCT06957808 ↗ Investigating the Effect of Diroximel Fumarate on Glutathione in Schizophrenia RECRUITING Rosetrees Trust NA 2025-01-10 Schizophrenia is a condition that causes symptoms like delusions, hallucinations, reduced motivation and muddled thinking. It is a common, severe and disabling psychiatric illness affecting about 1/100 (1%) of people. It is ranked the third most disabling illness worldwide. Six in seven patients do not recover from the illness in 6-12 months and continue to experience psychotic symptoms. Therefore, there is a strong unmet need for new evidence-based treatments to target the neurobiology underlying schizophrenia. There is increasing evidence to indicate that glutathione (GSH), the main brain antioxidant, is abnormal in schizophrenia and may provide a new treatment target. In this study we plan to determine whether Diroximel Fumarate (DRF) (currently a treatment for a brain disorder called multiple sclerosis) can increase GSH in the brain of patients with schizophrenia using a brain scan (MRI) and explore whether changes in GSH are related to other brain measures (measured with MRI and EEG- which measures electrical activity in the brain), blood markers of GSH, and symptoms. During this study 30 people with schizophrenia will be recruited. They will take the drug DRF for two weeks, a computer will then decide randomly whether each person will continue to take DRF or a placebo/dummy pill for another two weeks. During this part of the study neither the patients nor the researchers will know which type of drug the patient is taking. Brain GSH and the other measures described will be assessed before and after taking the DRF and placebo/dummy pill. At the end of the study (2027), we will see if taking DRF alters the brain chemical (GSH) in people with schizophrenia and whether this is linked to other measures and symptoms. It will also give researchers information about the best way to design future studies for patients with schizophrenia using this drug.
