• Has a history of gastrointestinal (GI) surgery (except appendectomy or cholecystectomy that occurred more than 6 months prior to screening), irritable bowel syndrome, inflammatory bowel disease (Crohn's disease, ulcerative colitis), or other clinically significant and active GI condition per the investigator's discretion.
• History of clinically significant recurring or active GI symptoms (e.g., nausea, diarrhea, dyspepsia, constipation) within 90 days of screening, including symptoms that require the initiation of symptomatic medical treatment (e.g., initiation of a medication to treat gastroesophageal reflux disease) or a change in symptomatic medical treatment (e.g., an increase in dose) within 90 days prior to screening.
• Evidence of current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection within 14 days prior to Screening, between screening and baseline visit (Day 1), or at baseline visit (Day 1), including but not limited to a fever (temperature >37.5 degrees Celsius [°C]), new and persistent cough, breathlessness, or loss of taste and/or smell. Evidence of current SARS-CoV-2 infection within 14 days prior to Screening or during Screening, will be eligible for rescreening, provided that the participant is asymptomatic for 14 days prior to rescreening.
• Have close contact within 14 days prior to Day 1 with individual(s) with suspected SARS-CoV-2 infection.
• For participants who had close contact with individual(s) with suspected SARS-CoV-2 infection within 14 days prior to Day 1, as determined by the Investigator, will be eligible for rescreening, provided that the participant is asymptomatic for 14 days after the contact.
• Previous participation in this study or previous studies with DRF, DMF, or MMF.

• History of, or ongoing, malignant disease, including solid tumors and hematologic malignancies.
• History of systemic hypersensitivity reaction to DRF, dimethyl fumarate (DMF), MMF or other fumaric esters, the excipients contained in the formulation, and if appropriate, any diagnostic agents to be administered during the study.
• History or positive test result at screening for human immunodeficiency virus (HIV).
• Has a clinically significant history of suicidal ideation or suicidal behavior occurring in the past 12 months as assessed by the C-SSRS at Screening.
