An overview of Galapagos, its strategy and portfolio in H1 2021

Forward with confidence

Letter from the management

Dear shareholders,

The business of biotech is not like any other. It takes grit, patience, persistence, and a lot of hard work, with the risk of disappointing outcomes of clinical trials, perhaps especially when going for novel targets. We remain excited about the potential of our target discovery platform, our drug development capacities, and the strength of our teams, but we have to acknowledge that we experienced significant setbacks in recent quarters, and we drew important lessons from them. The discontinuation of the global Phase 3 program with ziritaxestat, announced earlier this year, in particular was a turning point. Halting this late-stage program in idiopathic pulmonary fibrosis (IPF) triggered a process of reassessment of our R&D efforts, and we consequently announced a number of portfolio decisions in our first quarter reporting, along with a significant cost-savings program. While not easy, we are convinced that it is crucial to right-size the organization for the Galapagos that we are today, in order to put us on the strongest footing for the future.

We continue to work hard on building our pipeline, and we recently announced positive topline data with GLPG3667, our proprietary selective TYK2 compound, in psoriasis (Pso). The clinical activity observed at 4 weeks for the high dose of GLPG3667 versus placebo in this Phase 1b trial, combined with the encouraging safety and tolerability profile, warrant further progression of GLPG3667. We currently are running a further dose escalation study in healthy volunteers, and we intend to launch a Phase 2b dose finding study in Pso as well as a Phase 2 study in ulcerative colitis (UC) with GLPG3667 in 2022.

Early Q3, we also announced the read-outs of the first patient studies with SIK2/3 inhibitor GLPG3970, pointing to the potential of SIK inhibition as a novel mode of action in inflammation. While the study in rheumatoid arthritis (RA; LADYBUG) did not give a signal, we observed clinical activity in Pso (CALOSOMA) as well as biologically important effects in ulcerative colitis (UC; SEA TURTLE) on a number of objective endpoints. GLPG3970 was generally safe and well tolerated across the three 6-week long trials. We are keen to draw learnings from our findings, including from additional biomarker data and analyses available later this year, as we work on optimizing the pharmacology of additional SIK compounds in our Toledo portfolio. We plan to bring an additional SIK2/3 molecule into a healthy volunteer Phase 1 study in 2022.

We are also proud of the progress achieved to date with our European commercial launch of filgotinib, under the brand name Jyseleca® . The transition from Gilead to us remains on track to be completed by year-end, and over the first half of 2021, we achieved a number of key milestones in gaining access and reimbursement. We are pleased to announce first sales of filgotinib in 11 countries. We are excited to bring our first commercial product to people suffering from RA, and we are looking forward to regulatory updates on the potential European approval of filgotinib in UC before year-end.

On the development side, we announced the start of our first large-scale real-world evidence program, the FILOSOPHY Phase 4 European outcomes study in RA. Earlier this year, we also presented encouraging exploratory data from the DIVERGENCE 2 study with filgotinib in fistulizing Crohn's disease (CD), corroborating data from the DIVERGENCE 1 study in small bowel CD.

We also announced publication of the Phase 3 SELECTION full results with filgotinib in UC in The Lancet.

THE GALAPAGOS GROUP

We continue to advance our refocused, differentiated portfolio of pipeline assets in our core areas of inflammation, fibrosis and kidney disease, as the below overview shows:

Differentiated pipeline

H1 2021 financial result

Details of financial results

Due to the sale of our fee-for-service business (Fidelta) to Selvita on 4 January 2021 for a total consideration of €37.1 million (including customary adjustments for net cash and working capital), the results of Fidelta are presented as "Net profit from discontinued operations" in our unaudited condensed consolidated income statement.

Revenues and other income from continuing operations

Our revenues and other income from continuing operations for the first six months of 2021 amounted to €277.2 million, compared to €217.2 million for the first six months of 2020.

Revenues amounted to €253.7 million for the first six months of 2021 compared to €194.4 million for the first six months of 2020, and were higher mainly driven by the increase in revenue recognition of upfront consideration and milestone payments received in the scope of the collaboration with Gilead for filgotinib amounting to €136.1 million for the first six months of 2021 (€75.0 million for the same period last year).

Other income (€23.6 million vs €22.8 million for the same period last year) increased, mainly driven by higher grant income.

Results from continuing operations

We realized a net loss from continuing operations of €77.2 million for the first six months of 2021, compared to a net loss of €169.2 million for the first six months of 2020.

We reported an operating loss amounting to €97.6 million for the first six months of 2021, compared to an operating loss of €134.4 million for the same period last year.

Our R&D expenditure in the first six months of 2021 amounted to €268.8 million, compared to €262.9 million for the first six months of 2020. This increase, primarily related to our filgotinib program and our Toledo program, was compensated by a decrease for ziritaxestat, the OA program with GLPG1972, and the program in atopic dermatitis (AtD) with MOR106. Personnel costs increased due to an increase in headcount compared to the same period last year, and increased costs of our subscription right plans. This last factor, together with increased costs of the commercial launch of filgotinib in Europe, contributed to the increase in our G&A and S&M expenses which were €106.0 million in the first six months of 2021, compared to €88.7 million in the first six months of 2020.

We reported a non-cash fair value gain from the re-measurement of initial warrant B issued to Gilead, amounting to €2.8 million, mainly due to the decreased implied volatility of the Galapagos share price as well as its evolution between 31 December 2020 and 30 June 2021.

Net other financial income in the first six months of 2021 amounted to €17.1 million, compared to net other financial loss of €13.0 million for the first six months of 2020, which was primarily attributable to €33.4 million of currency exchange gain on our cash and cash equivalents and current financial investments in U.S. dollars, to €8.7 million of negative changes in (fair) value of current financial investments and financial assets and to €4.4 million of interest charges. The other financial expenses also contained the effect of discounting our long term deferred income of €4.8 million.

Results from discontinued operations

The net profit from discontinued operations for the six months ended 30 June 2021 consisted of the gain on the sale of Fidelta, our fee-for-services business, for €22.2 million.

Group net results

The group realized a net loss for the first six months of 2021 amounting to €55.0 million, compared to a net loss of €165.6 million for the same period in 2020.

Cash position

Current financial investments and cash and cash equivalents totaled €5,006.6 million on 30 June 2021 (€5,169.3 million on 31 December 2020, including the cash and cash equivalents included in the assets classified as held for sale).

Total net decrease in current financial investments and cash and cash equivalents amounted to €162.7 million in the first six months of 2021, compared to a net decrease of €214.3 million during the first six months of 2020. This net decrease was composed of (i) €223.2 million of operational cash burn,1 offset by (ii) €2.6 million of cash proceeds from capital and share premium increase from exercise of subscription rights in the first six months of 2021, (iii) €5.8 million of negative changes in (fair) value of current financial investments and €35.0 million of mainly positive exchange rate differences, (iv) €28.7 million cash in from the disposal of Fidelta, net of cash disposed.

Finally, our balance sheet on 30 June 2021 held a receivable from the French government (Crédit d'Impôt Recherche 2 ) and a receivable from the Belgian Government for R&D incentives, for a total of €142.7 million.

Outlook 2021

Following the strategic exercise announced at Q1, we are focused on developing our resized pipeline and implementing our savings program, while executing on the successful commercial launch of Jyseleca and diligently evaluating business development opportunities.

In 2021, we expect the European regulatory assessment of filgotinib for the treatment of UC and anticipate both an opinion from Committee for Medicinal Products for Human Use (CHMP) and a decision from the European Commission later this year. We also expect additional reimbursement decisions for filgotinib in RA across a number of European countries. We are on track to complete the transition from our collaboration partner Gilead to us of the full European commercial operations for filgotinib by year-end, and we anticipate reporting on our own European sales of filgotinib starting in the second half of the year.

Completion of the recruitment in the global DIVERSITY Phase 3 trial with filgotinib in CD by our collaboration partner Gilead is also expected later this year.

With regard to our SIK portfolio, we are advancing our SIK3 inhibitor GLPG4399 in healthy volunteers this year, and we aim to advance a follow-up SIK2/3 preclinical candidate into the clinic in 2022.

Following the positive topline data from our TYK2 inhibitor, GLPG3667, we currently are running an extended dose escalation study in healthy volunteers, and we are preparing for a Phase 2b trial in Pso and a Phase 2 trial in UC next year.

In our other programs, by year-end we intend to finalize recruitment into the GLPG2737 Phase 2a trial in polycystic kidney disease.

1 We refer to the note on the cash position of our condensed consolidated interim financial statements for an explanation and reconciliation of this alternative performance measure.

2 Crédit d'Impôt Recherche refers to an innovation incentive system underwritten by the French government.

Following the previously announced review of our plans for 2021, we reiterate our guidance for full year 2021 operational cash burn of €580 to €620 million.

We want to express our gratitude for your support and your patience, as we are working hard to rebuild the confidence in Galapagos.

COVID-19 impact

During the COVID-19 pandemic, we continue to innovate to accommodate for the current situation and minimize the impact to operations. We closely follow local governmental measures and apply these as appropriate within our organization, guided and supported by our dedicated COVID-19 task force teams. All local and global task force teams meet regularly and make recommendations directly to the COO.

We report the following impacts:

▪ Staff

We continue to follow the strict measures put in place to help prevent the spread of the virus and protect the health of our staff. We rolled out our global and site-specific business continuity plans and took appropriate recommended precautions.

During lock-down periods, we arranged for essential tasks to be carried out within our facilities. Consequently, the majority of our Research staff continue working from the offices/labs, with periodic exceptions for local lockdowns during which no staff is allowed to come into the facilities. For those employees coming to the office, we have stringent cleaning and sanitation protocols in place, and we strictly respect social distancing policies at all times in order to minimize risk of exposure.

As the global pandemic continues into 2021, we aim to maintain our strict measures and protocols to ensure safety and good health of our employees. Strictly following the local governmental measures, we start to welcome back our employees on site.

▪ Research portfolio

By prioritizing the most advanced projects very early on, and increasing the flexibility of our staff in the labs within projects, we sustain our research progress, and continue our early drug research and the implementation of new modalities for target or drug discovery.

So far, we note no material impact of the COVID-19 pandemic on our research portfolio.

▪ Development portfolio

We have a business continuity plan for our clinical development programs. We closely monitor each program in the context of the current global and local situation of the pandemic and the associated specific regulatory, institutional, and government guidance and policies related to COVID-19. Within the boundaries of these guidances and policies, and in consultation with our CROs and clinical trial sites, we applied various measures to minimize the impact of the COVID-19 pandemic on our clinical development programs, with the primary aim to ensure the safety of our trial participants and to preserve the data integrity and scientific validity of the trials. These measures continue to be implemented on a case-by-case basis, tailored to the specific study and country needs at any given time, with specific attention paid to vulnerable populations and the use of investigational medicines with immunosuppressive properties. The measures include, among others, increased, transparent communication to all stakeholders and the direct supply of investigational medicines to patients. For each clinical trial, we actively monitor and document the impact of COVID-19 on the study where necessary and facilitate the interpretation and reporting of results.

Following the global increase of COVID-19 testing and vaccinations, we issued an internal guidance on the impact of testing and vaccinations on clinical trials.

▪ Filgotinib filing process UC

As of publication of this H1 report, our collaboration partner Gilead has not been informed by regulatory agencies of approval timeline delays related to the pandemic.

▪ Manufacturing and supply chain

To date, there has been no COVID-19 impact to the commercial supply of filgotinib. Gilead also confirmed that all sites involved in the manufacturing of filgotinib are established sites that currently manufacture other Gilead marketed products and are in good standing with the FDA and are GMP certified. Under the revised agreement with Gilead for filgotinib in Europe, Galapagos plans to become the marketing authorization holder of filgotinib in Europe by year-end 2021, and then become responsible for manufacturing. We will work with the same manufacturing sites as Gilead except for secondary packaging and labelling for which a new vendor has been selected.

▪ Commercial organization

The form of outreach of our commercial teams to physicians and hospitals was impacted by the COVID-19 pandemic and consequent travel restrictions, and thus became partially virtual. The teams invested in digital channels as part of the overall commercial build strategy, and these channels are being utilized during our ongoing commercial launch. Thus far we note no material impact on our commercial operations due to travel restrictions, nor has there been an impact of COVID-19 on our ability to engage in market access discussions. Nevertheless, healthcare systems are under pressure across Europe, increasing the risk of future volatility in reimbursement procedures and potentially reducing the number of new therapy options initiated by healthcare providers.

Notes to the unaudited condensed consolidated interim financial statements for the first six months of 2021

Basis of preparation

These condensed consolidated interim financial statements have been prepared in accordance with IAS 34 'Interim Financial Reporting' as adopted by the European Union and as issued by the IASB. The condensed consolidated interim financial statements do not contain all information required for an annual report and should therefore be read in conjunction with our Annual Report 2020.

The condensed consolidated interim financial statements were subject to a review by the statutory auditor, but have not been audited.

Impact of COVID-19 on the financial statements

To date, we have experienced limited impact on our financial performance, financial position, cash flows and significant judgements and estimates, although we continue to face additional risks and challenges associated with the impact of the outbreak.

Significant accounting policies

There were no significant changes in accounting policies applied by us in these condensed consolidated interim financial statements compared to those used in the most recent annual consolidated financial statements of 31 December 2020.

New standards and interpretations applicable for the annual period beginning on 1 January 2021 did not have any impact on our condensed consolidated interim financial statements.

We have not early adopted any other standard, interpretation, or amendment that has been issued but is not yet effective.

Revenues and other income

Total revenues 253,664 194,404

Revenues (€253.7 million for the first six months of 2021, compared to €194.4 million for the first six months of 2020) were higher mainly driven by the increase in revenue recognition of upfront consideration and milestone payments received in the scope of the collaboration with Gilead for filgotinib amounting to €136.1 million for the first six months of 2021 (€75.0 million for the same period last year). The increased cost share and the additional upfront consideration as a consequence of the renegotiated arrangement between Gilead and Galapagos in December 2020, as well as the milestones for the approval of filgotinib in Europe and Japan achieved in the third quarter of 2020, all contributed to this increase in revenues.

The rollforward of the outstanding balance of the current and non-current deferred income between 1 January 2021 and 30 June 2021 can be summarized as follows:

(*) The outstanding balance at 30 June 2021 and at 31 December 2020 comprises the issuance liability for the subsequent warrant B and the upfront payment allocated to the drug discovery platform.

(**) With regard to the additional consideration received for the extended cost sharing for filgotinib, we assume the existence of a significant financing component reflecting the time value of money on the estimated recognition period.

Other income

Other income (€23.6 million for the first six months of 2021, compared to €22.8 million for the first six months of 2020) increased by €0.8 million, mainly driven by higher grant income.

Results from continuing operations

We realized a net loss from continuing operations of €77.2 million for the first six months of 2021, compared to a net loss of €169.2 million in the first six months of 2020.

We reported an operating loss amounting to €97.6 million for the first six months of 2021, compared to an operating loss of €134.4 million for the same period last year.

Our R&D expenditure in the first six months of 2021 amounted to €268.8 million, compared to €262.9 million in the first six months of 2020. This increase, primarily related to our filgotinib program and our Toledo program, was compensated by a decrease for ziritaxestat, the OA program with GLPG1972, and the AtD program with MOR106. Personnel costs increased by €11.7 million from €82.5 million in the first six months of 2020 to €94.2 million in the first six months of 2021. This increase is due to an increase in headcount compared to the same period last year, and increased costs of our subscription right plans.

FINANCIAL STATEMENTS

The table below summarizes our R&D expenditure for the six months ended 30 June 2021 and 2020, broken down by program.

Six months ended 30 June
(thousands of €) 2021 2020
Filgotinib program (87,840) (65,541)
Ziritaxestat program (19,418) (29,790)
OA program with GLPG1972 (1,241) (12,499)
Toledo program (52,235) (37,557)
AtD program with MOR106 (52) (9,518)
Other programs (108,040) (107,997)
Total research and development expenditure (268,826) (262,901)

Our G&A and S&M expenses were €106.0 million in the first six months of 2021, compared to €88.7 million in the first six months of 2020. This increase mainly resulted from higher personnel costs for €15.3 million (€64.4 million in the first six months of 2021 compared to €49.1 million in the same period last year). This increase was due to a planned headcount increase following the commercial launch of filgotinib in Europe as well as higher costs of the subscription right plans.

In the first six months of 2021, we reported a non-cash fair value gain from the re-measurement of initial warrant B issued to Gilead, amounting to €2.8 million, mainly due to the decreased implied volatility of the Galapagos share price as well as its evolution between 31 December 2020 and 30 June 2021.

Net other financial income in the first six months of 2021 amounted to €17.1 million (as compared to net other financial loss of €13.0 million in the same period last year), which was primarily attributable to €33.4 million of currency exchange gains on our cash and cash equivalents and current financial investments in U.S. dollars (as compared to €5.5 million currency exchange gains in the first six months of 2020) and €5.8 million negative changes in (fair) value of current financial investments (€12.5 million in the same period last year). The other financial expenses also contained the effect of discounting our long term deferred income of €4.8 million (€8.7 million in the same period last year) as well as the fair value loss of financial assets held at fair value through profit or loss of €2.9 million (€0.4 million in the same period last year).

Cash position

Cash and cash equivalents and current financial investments totaled €5,006.6 million on 30 June 2021 (€5,169.3 million on 31 December 2020, including the cash and cash equivalents included in the assets classified as held for sale).

A net decrease of €162.7 million in cash and cash equivalents and current financial investments was recorded during the first six months of 2021, compared to a net decrease of €214.3 million during the first six months of 2020. This net decrease was composed of (i) €223.2 million of operational cash burn, (ii) offset by €2.6 million of cash proceeds from capital and share premium increase from exercise of subscription rights in the first six months of 2021, (iii) €5.8 million of negative changes in (fair) value of current financial investments and €35.0 million of mainly positive exchange rate differences, and (iv) €28.7 million cash in from disposal of subsidiaries, net of cash disposed.

The operational cash burn (or operational cash flow if this performance measure is positive) is a financial measure that is not calculated in accordance with IFRS. Operational cash burn/cash flow is defined as the increase or decrease in our cash and cash equivalents (excluding the effect of exchange rate differences on cash and cash equivalents), minus:

i. the net proceeds, if any, from share capital and share premium increases included in the net cash flows generated from/used in (–) financing activities

ii. the net proceeds or cash used, if any, in acquisitions or disposals of businesses; the movement in restricted cash and movement in current financial investments, if any, included in the net cash flows generated from/used in (–) investing activities.

This alternative performance measure is in our view an important metric for a biotech company in the development stage.

The following table represents a reconciliation of the operational cash burn:

Six months ended 30 June
(thousands of €) 2021 2020
Increase in cash and cash equivalents (excluding effect of exchange differences) 477,448 523,222

Cash in from disposal of subsidiaries, net of cash disposed of (28,696) -
Total operational cash burn (223,196) (230,486)

Cash and cash equivalents and current financial investments comprised cash at banks, short-term bank deposits, treasury bills and money market funds that are readily convertible to cash and are subject to an insignificant risk of changes in value. Our cash management strategy monitors and optimizes our liquidity position. Our cash management strategy allows short-term deposits with an original maturity exceeding three months while monitoring all liquidity aspects. Cash and cash equivalents comprised €1,411.7 million of term deposits which all had an original maturity longer than three months. All cash and cash equivalents are available upon maximum three months notice period and without significant penalty. Cash at banks were mainly composed of notice accounts and term deposits. Our credit risk is mitigated by selecting a panel of highly rated financial institutions for our deposits.

Cash invested in highly liquid money market funds represented €1,060.3 million (€1,571.9 million on 31 December 2020) and are presented as current financial investments on 30 June 2021. The current financial investments also include treasury bills, amounting to €1,303.7 million on 30 June 2021 (€1,454.4 million on 31 December 2020). Our portfolio of treasury bills contains only AAA rated paper, issued by Germany and The Netherlands. Our money market funds portfolio consists of AAA short-term money market funds with a diversified and highly rated underlying portfolio managed by established fund management companies with a proven track record leading to an insignificant risk of changes in value.

FINANCIAL STATEMENTS

On 30 June 2021, our cash and cash equivalents and current financial investments included \$973.3 million held in U.S. dollars (\$1,418.9 million on 31 December 2020) which could generate foreign exchange gains or losses in our financial results in accordance with the fluctuation of the EUR/U.S. dollar exchange rate as our functional currency is EUR. The foreign exchange loss (–)/gain in case of a 10% change in the EUR/U.S. dollar exchange rate amounts to €81.9 million.

Finally, our balance sheet held R&D incentives receivables from the French government (Crédit d'Impôt Recherche), to be received in four yearly tranches, and R&D incentives receivables from the Belgian Government, for a total of €142.7 million as at 30 June 2021.

Capital increase

Related party transactions

On 30 April 2021, the members of the management board were offered new subscription rights under Subscription Right Plan 2021 BE, subject to acceptance. A first portion of the number of accepted subscription rights under Subscription Right Plan 2021 BE and the final number of accepted subscription rights under Subscription Right Plan 2021 RMV and Subscription Right Plan 2021 ROW were enacted by notary deed on 2 July 2021. For four members of the management board, the suspensive condition of acceptance is still outstanding. The subscription rights have an exercise term of eight years as of the date of the offer. The exercise price of the subscription rights is €64.76 (the closing price of the Galapagos share on Euronext Amsterdam and Brussels on the day preceding the date of the offer). Each subscription right gives the right to subscribe for one new Galapagos share. For all the beneficiaries under Subscription Right Plan 2021 BE the subscription rights vest only and fully on the first day of the fourth calendar year following the calendar year in which the grant was made. The subscription rights are not transferable and can in principle not be exercised prior to 1 January 2025. Subscription rights granted under Subscription Right Plan 2021 RMV and Subscription Right Plan 2021 ROW vest in instalments: with 25% of each grant being exercisable as of 1 January 2023, 25% as of 1 January 2024 and 50% (the remainder) as of 1 January 2025.

On 5 May 2021, the members of the management board were offered new restricted stock units ('RSUs'), subject to acceptance. The RSUs are offered for no consideration. Four members of the management board accepted all RSUs offered to them. Each RSU represents the right to receive, at Galapagos' discretion, one Galapagos share or a payment in cash of an amount equivalent to the volume-weighted average price of the Galapagos share on Euronext Brussels over the 30-calendar day period preceding the relevant vesting date. The RSU grant will vest in

Events after the end of the reporting period

There were no adjusting events nor material non-adjusting events to be reported.

Approval of interim financial statements

The interim financial statements were approved by the supervisory board on 2 August 2021.

Report on the review of the condensed consolidated interim financial statements for the six-month period ended 30 June 2021

In the context of our appointment as the company's statutory auditor, we report to you on the condensed consolidated interim financial statements. These condensed consolidated interim financial statements comprise the consolidated statements of financial position as at 30 June 2021, the consolidated statements of income and comprehensive income/loss, the consolidated statement of changes in equity and the consolidated cash flow statements for the period of six months then ended, as well as notes.

Report on the condensed consolidated interim financial statements

We have reviewed the condensed consolidated interim financial statements of Galapagos NV ("the company") and its subsidiaries (jointly "the group"), prepared in accordance with International Accounting Standard (IAS) 34, "Interim Financial Reporting" as adopted by the European Union.

The consolidated statement of financial position shows total assets of 5 430 617 (000) EUR and the consolidated statement of income shows a consolidated loss (group share) for the period then ended of 54 968 (000) EUR.

The supervisory board of the company is responsible for the preparation and fair presentation of the condensed consolidated interim financial statements in accordance with IAS 34, "Interim Financial Reporting" as adopted by the European Union. Our responsibility is to express a conclusion on these condensed consolidated interim financial statements based on our review.

Scope of review

We conducted our review of the condensed consolidated interim financial statements in accordance with International Standard on Review Engagements (ISRE) 2410, "Review of interim financial information performed by the independent auditor of the entity". A review of interim financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit performed in accordance with the International Standards on Auditing (ISA) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion on the condensed consolidated interim financial statements.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the condensed consolidated interim financial statements of Galapagos NV have not been prepared, in all material respects, in accordance with IAS 34, "Interim Financial Reporting" as adopted by the European Union.

Simple endoscopic score for CD, involving review of five pre-defined bowel segments, assigning values from 0 (unaffected) to 3 (highly affected)

Short interfering RNA

A research tool that is used to silence the activity of specific genes

SIK

Salt-inducible kinase. This is the target family for the portfolio of molecules in the Toledo program

Sjögrens syndrome

Sjögren's Syndrome is a systemic inflammatory disease which can be felt throughout the body, often resulting in chronic dryness of the eyes and mouth

S&M expenses

Sales and marketing expenses

Small bowel CD (SBCD)

CD causes chronic inflammation and erosion of the intestines. It can affect different regions of gastrointestinal tract including the stomach and small and large intestines. While isolated SBCD is an uncommon presentation of CD, involvement of some portion of the small bowel, particularly the ileum, is common

Statin

Statins are a class of lipid-lowering medications that reduce illness and mortality in those who are at high risk of cardiovascular disease. They are the most common cholesterol-lowering drugs. Low-density lipoprotein (LDL) carriers of cholesterol play a key role in the development of atherosclerosis and coronary heart disease via the mechanisms described by the lipid hypothesis

Systemic lupus erythematosus

An autoimmune disease, with systemic manifestations including skin rash, erosion of joints or even kidney failure

TAPINOMA

Phase 1b Proof of Concept trial with SIK2/3 inhibitor GLPG3970 in SLE

Target

Proteïn that has been shown to play a role in a disease process and that forms the basis of a therapeutic intervention or discovery of a medicine

Target discovery

Identification and validation of proteins that have been shown to play a role in a disease process

TEAE

Treatment Emergent Adverse Event, is any event not present prior to the initiation of the treatments or any event already present that worsens in either intensity or frequency following exposure to the treatments

Technology access fee

License payment made in return for access to specific technology (e.g. compound or virus collections)

Topical corticosteroids

Corticosteroids which are administered through the skin using an ointment

Transcription

The process of making an RNA copy of a DNA gene sequence

Translation

The process by which a protein is synthetized from mRNA

TYK

Tyrosine kinase is an enzyme that can transfer a phosphate group from ATP to the tyrosine residues of specific proteins inside a cell. It functions as an "on" or "off" switch in many cellular functions. Tyrosine kinases belong to a larger class of enzymes known as protein kinases which also attach phosphates to other amino acids such as serine and threonine. GLPG3667 is a reversible and selective TYK2 kinase domain inhibitor

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)

Venous thrombotic events

When a blood clot breaks loose and travels in the blood, this is called a venous thromboembolism (VTE). The abbreviation DVT/PE refers to a VTE where a deep vein thrombosis (DVT) has moved to the lungs (PE or pulmonary embolism)

Ziritaxestat

Formerly known as GLPG1690. Ziritaxestat is a novel drug candidate targeting autotaxin; all development with ziritaxestat was discontinued in February 2021
