Saniona provides update on ongoing review of tesofensine in Mexico


June 25, 2021

Saniona (OMX: SANION), a clinical stage biopharmaceutical company focused on rare diseases, today announced that its partner Productos Medix, S.A de S.V, (Medix) has provided Saniona with an update on the Mexican regulatory authority Comisión Federal para la Protección contra Riesgos Sanitarios (COFEPRIS)’s ongoing review of tesofensine for the treatment of obesity.

According to Medix, as part of the ongoing review process, the tesofensine application was reviewed by a COFEPRIS technical committee on new molecules (El Comité de Moléculas Nuevas). The committee was unable to provide a favorable opinion on tesofensine at this time and cited the need for additional information regarding certain topics, including weight loss maintenance. Medix informed Saniona that it will gather the requested information and continue discussions with the committee as soon as possible, and that it fully intends to continue to pursue the process of seeking approval for tesofensine. However, Medix advised that the continuing discussions with the committee may delay the anticipated final approval decision from COFEPRIS into 2022.

Medix licensed the rights to develop and commercialize tesofensine in Mexico and Argentina from Saniona in 2016. Saniona retains all rights to tesofensine in the rest of the world.
