Introduction
Multiple sclerosis (MS) is a chronic autoimmune disease in which the immune system mistakenly attacks the protective covering of nerve fibers in the central nervous system. Relapsing forms of MS involve periods of relapses and remissions, where symptoms worsen and improve over time. Vumerity, also known by its generic name diroximel fumarate, is an oral medication approved by the U.S Food and Drug Administration (FDA) for the treatment of relapsing forms of MS.
Mechanism of Action
Vumerity belongs to a class of medications known as fumarates. Its exact mechanism of action is not fully understood, but it is thought to work by modulating the immune system. Vumerity is believed to activate a specific pathway called the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway, which plays a role in the body's defense against oxidative stress and inflammation. Through the activation of this pathway, Vumerity may help reduce the damage caused by the immune system in patients with MS.
Effectiveness and Benefits
Multiple clinical trials have shown the effectiveness of Vumerity in reducing the frequency of relapses and slowing down the progression of RMS. In a randomized, double-blind study, Vumerity demonstrated a significant reduction in annualized relapse rates compared to a placebo. Vumerity also showed favorable effects on other important measures of disease activity and progression, including MRI lesion activity and disability progression. The benefits of Vumerity include its convenient oral formulation, once-daily dosing, and a lower incidence of gastrointestinal side effects compared to other MS medications.
Safety Profile
In clinical trials, the most common side effects associated with Vumerity were flushing, stomach problems, and diarrhea. Most of these side effects were mild to moderate and typically resolved over time. It is important for patients to discuss any concerns or specific medical conditions with their healthcare provider before starting Vumerity. Additionally, Vumerity may have potential drug interactions with certain medications, so it is essential to inform the healthcare provider about all current medications and supplements.
