The primary objective of the study is to evaluate whether premedication with 325 mg microcoated aspirin (ASA) tablet or a slow-titration dosing schedule of BG00012 reduces the incidence and severity of flushing and GI events following oral administration of BG00012 dosed at 240 mg twice a day (BID) in healthy volunteers. The secondary objective of this study is to evaluate the safety and tolerability of BG00012 when administered orally as a 240 mg BID dose regimen with and without 325 mg ASA premedication or following a slow-titration dosing schedule in healthy volunteers.

Each capsule contains 120 mg dimethyl fumarate (DMF). Fast titration involves taking one 120 mg capsule in the morning and one in the evening (240 mg daily) for one week, and then escalating to a dose of 480 mg daily (two capsules morning and evening) for the remainder of the study.Slow titration expands the dose escalation time to 4 weeks.

Percentage of Participants Reporting Overall Flushing Events During the Overall Treatment Period, as Assessed by the Modified Flushing Severity Scale (MFSS)
Participant-reported flushing side effect events during the treatment period recorded on the eDiary as assessed by MFSS. MFSS questionnaire measures the side effects related to flushing following drug administration. Flushing means redness, warmth, tingling or itching of the skin. This questionnaire relates only to the period of time since the investigational drug was administered and was to be completed within 10 hours of taking the study drug (2 times/day). Each question is rated on a scale from 0 (no flushing side effects) to 10 (extreme flushing side effects).

Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious AEs (SAEs)
AE: any untoward medical occurrence that does not necessarily have a causal relationship with treatment. SAE: any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the subject at immediate risk of death; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect; any other medically important event that, in the opinion of the Investigator, may jeopardize the subject or may require intervention to prevent one of the other outcomes. An AE was considered treatment-emergent if it occurred after the start of study treatment or was present prior to the start of study treatment but subsequently worsened.
