Total collaboration revenues






The 2022 comparative has been restated to reflect the impact of classifying the Jyseleca® business as discontinued operations in 2023.

We recognize the consideration from Gilead allocated to the drug discovery platform on a linear basis over the 10-year period of our collaboration, of which we recognized €230.2 million in revenue in 2023. We expect to recognize the same amount in the coming years, until the end of the 10-year period.

Since signing of the letter of intent with Alfasigma in October 2023, we classified all activities that were directly related to the Jyseleca® business, including the revenue recognition related to the filgotinib performance obligation, as discontinued operations in accordance with IFRS 5. We refer to note 5 “Discontinued Operations” for additional information.

For the year ended 31 December 2023 we also recognized in revenue €9.5 million of royalties from Gilead on filgotinib. The royalties on sales of Jyseleca® performed by Gilead in Japan were not reported as discontinued operations as we still have the right to receive those royalties on future sales made by Gilead and its commercialization partners (this right is not subject to transfer to Alfasigma as part of the transfer of the Jyseleca® business to them).


Collaboration with Gilead

We refer to note 2 of this financial report for a general description of our collaboration with Gilead.

In addition, we concluded as follows for the remaining performance obligations:

Access rights to the drug discovery platform, option rights and R&D activities

  • The revenue allocated to the drug discovery platform is recognized over time as Gilead receives exclusive access to our drug discovery platform and option rights on our current and future pipeline as well as R&D activities during the collaboration term. Management concluded that an equal spread over the collaboration period is the most reliable and appropriate recognition method.
  • At inception of the collaboration (July 2019) we assessed the appropriate period over which to recognize the drug discovery platform revenue to be 10 years. This is because we granted exclusive rights over a 10-year period. However, if at the end of the 10-year period, some programs in existence as of this time would have reached the clinic (i.e. IND filed with regulatory authorities), the rights for those specific programs may be extended, for a maximum of three years. This critical estimate is reassessed at each year-end based on the evolution of our pipeline and is still valid per 31 December 2023.

Investigational New Drug (IND) Application
United States Federal law requires a pharmaceutical company to obtain an exemption to ship an experimental drug across state lines, usually to clinical investigators, before a marketing application for the drug has been approved. The IND is the means by which the sponsor obtains this exemption, allowing them to perform clinical studies
