Tegomil fumarate sold under the brand name Riulvy, is a medication used for the treatment of relapsing remitting multiple sclerosis. [1] It is taken by mouth. [1]
The mechanism of action of tegomil fumarate is not fully understood but it is thought to act via its main active metabolite monomethyl fumarate. [1] This metabolite activates the NRF2 transcriptional pathway, which reduces inflammation and modulates the activity of immune cells, thereby protecting the cells of the central nervous system from damage. [1]
Tegomil fumarate was authorized for medical use in the European Union in July 2025. [2]
Tegomil fumarate is indicated for the treatment of people aged thirteen years of age and older with relapsing remitting multiple sclerosis. [1]
In May 2025, the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Riulvy, intended for the treatment of adults and children from 13 years of age with relapsing remitting multiple sclerosis. [1] The applicant for this medicinal product is Neuraxpharm Pharmaceuticals, S.L. [1] Riulvy is a hybrid medicine of Tecfidera, which has been authorized in the EU since January 2014. [1] Riulvy contains a different active substance but acts via the same active metabolite as Tecfidera, monomethyl fumarate. [1] Tegomil fumarate was authorized for medical use in the European Union in July 2025. [1] [2]
