Intangible assets Intangible assets
Intangible assets are mainly comprised of the intellectual property underlying:
(i)The collaboration and license agreement with the French National Centre for Scientific Research (CNRS), Montpellier 2
University and the Curie.
(ii)Patents acquired through the acquisition of Prosynergia of €6,529 thousand. The patents are not yet amortized, similarly
to licenses, and are included in obefazimod CGU for impairment test purposes.
 
Licenses and patents recognized as Intangible assets are not amortized since they are not operating in a manner intended by the
management. As a consequence, and in accordance with IAS 36, those assets were subject to an annual impairment test as of
December 31, 2025, which did not result in any impairment loss. As of March 31, 2026, no indicator of impairment has been
identified.
