Pharmacological Class

Nrf2 pathway activator.

How Supplied

Caps—120

NO

Mechanism of Action

The mechanism by which monomethyl fumarate exerts its therapeutic effect in multiple sclerosis is unknown. Monomethyl fumarate has been shown in vitro and in vivo to activate the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway, which is involved in the cellular response to oxidative stress.

Bafiertam Warnings/Precautions

Warnings/Precautions

Obtain a CBC including lymphocyte count prior to initiation, after 6 months, and then every 6 to 12 months thereafter; consider interruption if lymphocyte counts <0.5×109/L persist for >6 months. Pre-existing low lymphocyte counts: not studied. Serious infections; consider withholding until resolved. Monitor for herpes zoster and other opportunistic infections; evaluate and treat if develop. Monitor serum aminotransferase, alkaline phosphatase, and total bilirubin prior to initiation and during treatment; discontinue if significant liver injury is suspected. Discontinue if anaphylaxis or angioedema occurs. Withhold and evaluate at first sign/symptom suggestive of PML. Monitor, evaluate, and discontinue if new or worsening severe GI signs/symptoms occur. Administration with non-enteric coated aspirin (up to 325mg) may reduce incidence/severity of flushing. Pregnancy. Nursing mothers.

Bafiertam Pharmacokinetics

Absorption

Following oral administration of Bafiertam 190 mg (two 95 mg monomethyl fumarate delayed-release capsules) under fasting conditions, the median Tmax of MMF is 4.03 hours; and the peak plasma concentration (Cmax) and overall exposure (AUC) of monomethyl fumarate are bioequivalent to those after oral administration of 240 mg dimethyl fumarate delayed-release capsule.

Distribution

From studies with dimethyl fumarate (the prodrug of Bafiertam), it is shown that the apparent volume of distribution of MMF varies between 53 and 73 L in healthy subjects. Human plasma protein binding of MMF is 27–45% and independent of concentration.

Metabolism

In humans, metabolism of MMF occurs through the tricarboxylic acid (TCA) cycle, with no involvement of the cytochrome P450 (CYP450) system. MMF, fumaric and citric acid, and glucose are the major metabolites of MMF in plasma.

Elimination

The plasma half-life of MMF is ~0.5 hour and no circulating MMF is present at 24 hours in the majority of individual following oral administration of Bafiertam 190 mg (two 95 mg monomethyl fumarate delayed-release capsules) under fasting conditions.
