6. Total net revenues

Product net sales

We reported product net sales of Jyseleca® for the year ended 31 December 2022 of €87.6 million, as compared to €14.8 million for the year ended 31 December 2021. Our counterparties for the sales of Jyseleca® during 2022 were mainly hospitals and wholesalers located across Europe. Jyseleca net sales have significantly grown driven by volume uptake of existing business and by new launches in both indications in multiple countries.

Net sales exclusively consisted of sales of Jyseleca® in Europe.

Cost of sales related to Jyseleca® net sales for the year ended 31 December 2022 amounted to €12.1 million, compared to €1.6 million for the year ended 31 December 2021.

Total collaboration revenues





Revenue recognition of non-refundable upfront payments, license fees and milestone payments related to the filgotinib agreement amounted to €174.4 million in 2022. 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 €230.4 million in 2022. For the year ended 31 December 2022 we also recognized in revenue €10.7 million of royalties from Gilead on filgotinib.

Additionally, we recorded in 2022 milestone payments of €2.0 million triggered by the initial sales of Jyseleca® in the Czech Republic and Portugal by our distribution and commercialization partner Sobi.

Allocation to performance obligations












Drug discovery platform (10 years)





With regard to the additional consideration received as a result of the Option, License and Collaboration agreement (14 July 2019) allocated to the filgotinib performance obligation, we assumed the existence of a significant financing component estimated to €44.5 million as of 31 December 2019 reflecting the time value of money on the estimated recognition period. This financing component was reassessed to €55.3 million as of 31 December 2020, to €57.3 million on 31 December 2021 and to €58.7 million on 31 December 2022.

In 2022 we received $20.0 million (€18.2 million) of milestone payments for the regulatory approval of filgotinib in UC in Japan and recognized €10.7 million of royalties from Gilead.

A summary of our main contracts with customers and distribution/commercialization partners is given below:

Collaboration with Gilead

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

We retain the following three performance obligations, of which the first one was satisfied completely in 2019; (i) the transfer of an extended license on GLPG1690, (ii) the granting of exclusive access to our drug discovery platform (i.e. the IP, technology, expertise and capabilities) during the collaboration period and exclusive option rights on our current and future clinical programs after Phase 2 (or, in certain circumstances, the first Phase 3 study) outside Europe and (iii) an increased cost share from 20/80 to 50/50 to 100/0 (for Group A activities only) on the global development activities of filgotinib, until we complete the remaining development activities (Group A and Group B activities).

We concluded as follows:

Determination of the total transaction price

  • We assessed that the contract modifications of 15 December 2020 and 6 September 2021 only change the scope of the filgotinib performance obligation and the changes in both fixed and variable consideration are reflective of the updated stand-alone selling price for the remaining activities of this performance obligation. As a result of these modifications, there were increases in the transaction price of €160.0 million and $15.0 million, respectively, which have been allocated in their entirety to the filgotinib performance obligation.

Financing component

  • Management has considered it is appropriate to adjust the part of the transaction price that was allocated to the filgotinib performance obligation, for the time value of money. The additional consideration as a result of the contract modification of 15 December 2020 has also been adjusted for the time value of money.

Filgotinib amendment

  • There is one single performance obligation under IFRS 15: the transfer of a license combined with performance of R&D activities. This is because we considered that the license is not distinct in the context of the contract.
  • The transaction price is currently composed of a fixed part, being non-refundable upfront and license fees and a variable part, being milestone payments, sales based milestones and sales based royalties, and cost reimbursements for R&D activities delivered. Milestone payments are included in the transaction price of the arrangement to the extent that it is highly probable that a significant reversal of revenue will not occur. Milestone payments received from Gilead are recognized in revenue over time till the end of the development plan. Sales based milestones and sales based royalties are also part of the arrangement and are recognized as revenues at a point in time at the moment they occur. During 2021 and 2022 we reported respectively €3.8 million and €10.7 million of revenues from royalties from Gilead.
  • Revenues, excluding sales based milestones and sales based royalties, are recognized over time through satisfaction of the performance obligation. The “cost-to-cost” input model is applied to measure the progress of the satisfaction of this performance obligation. The estimated costs to complete the performance obligation have been reassessed as a result of the contract modifications from 2020 and 2021.

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 2022.

Collaboration with Sobi

In October 2021, we signed an agreement with Sobi regarding the distribution of Jyseleca®. Sobi will distribute the medicine in Central and Eastern Europe, Greece, Portugal, and the Baltic countries.

All activities required to bring a new drug to the market. This includes preclinical and clinical development research, chemical and pharmaceutical development and regulatory filings of product candidates
Process by which new medicines are discovered and/or designed. At Galapagos, this is the department that oversees target and drug discovery research through to nomination of preclinical candidates
Formerly known as GLPG0634, commercial name is Jyseleca®. Small molecule preferential JAK1 inhibitor, approved in RA and UC in Europe and Japan. Phase 4 studies are ongoing in both RA and UC
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
Jyseleca® is the brand name for filgotinib
Major achievement in a project or program; in our alliances, this is usually associated with a payment
Phase 2
Second stage of clinical testing, usually performed in no more than several hundred patients, in order to determine efficacy, tolerability and the dose to use
Phase 3
Large clinical trials, usually conducted in several hundred to several thousand patients to gain a definitive understanding of the efficacy and tolerability of the candidate treatment; serves as the principal basis for regulatory approval
Ulcerative colitis (UC)
UC is an IBD causing chronic inflammation of the lining of the colon and rectum (unlike CD with inflammation throughout the gastrointestinal tract)
