The Phase 2b DARWIN 3 long term extension trial initially enrolled 739
patients, who received filgotinib 100 mg twice daily, 100 mg or 200 mg
once daily. Safety data are summarized in the table below. Results
represent treatment through 156 weeks or longer, and comprise 2,203
patient-years of exposure (PYE) to filgotinib.

The growing body of evidence from both the DARWIN 3 long-term extension
trial combined with the results of the FINCH 1, 2, and 3 trials,
represent a larger safety database in a broader population of RA
patients, spanning from those who are treatment-naive to those who have
failed biologics,” said John McHutchison, AO, MD, Chief Scientific
Officer, Head of Research and Development, Gilead Sciences.

The available safety data from the FINCH and DARWIN 3 studies, which
together included more than 2,700 patients receiving filgotinib, suggest
that filgotinib has the potential to deliver a much needed option for
treating people living with RA,” said Dr. Walid Abi-Saab, Chief Medical
Officer, Galapagos.

Filgotinib is an investigational agent and not approved anywhere
globally. Its efficacy and safety have not been established.

About the FINCH program

The FINCH Phase 3 program is investigating the efficacy and safety of
100 mg and 200 mg filgotinib once daily, in RA patient populations
ranging from early stage to biologic-experienced patients. FINCH 1
is a 52-week, randomized, placebo- and adalimumab-controlled trial in
combination with methotrexate (MTX) enrolling 1,759 adult patients with
moderately to severely active RA who have had inadequate response to
MTX. The primary endpoint is ACR20 at week 12. The trial includes
radiographic assessment at weeks 24 and 52. FINCH 2 was a
24-week, randomized, placebo-controlled trial in 449 patients who were
receiving conventional disease-modifying anti-rheumatic drugs (cDMARD),
and had a prior inadequate response to one or more biological therapies.
The primary endpoint was ACR20 at week 12. FINCH 3 is a 52-week,
randomized trial in 1,252 MTX-naïve patients to study filgotinib in
combination with MTX, as well as monotherapy. The primary endpoint is
ACR20 at week 24. Radiographic progression is also being assessed.

About the DARWIN 3 program

DARWIN 3 is an ongoing multi-center, open-label, long-term follow-up
safety and efficacy trial of subjects who completed either DARWIN 1 or
DARWIN 2, which were double-blind, placebo-controlled Phase 2b trials
for 24 weeks of treatment in patients with moderate to severe RA who
showed an inadequate response to methotrexate. DARWIN 1 (594 patients)
evaluated filgotinib as an addition to methotrexate, as once- and
twice-daily administration (once-daily and twice-daily dosing,
respectively) at three daily dose levels. DARWIN 2 (283 patients)
evaluated filgotinib as once-daily monotherapy administration
(once-daily dosing) at three dose levels. Both DARWIN 1 and DARWIN 2
achieved the primary endpoints (ACR20).

Galapagos Forward-Looking Statements

This release may contain forward-looking statements with respect to
Galapagos, including statements regarding Galapagos’ strategic
ambitions, the mechanism of action and potential safety and efficacy of
filgotinib, the anticipated timing of clinical studies with filgotinib
and the progression and results of such studies. Galapagos cautions the
reader that forward-looking statements are not guarantees of future
performance. Forward-looking statements involve known and unknown risks,
uncertainties and other factors which might cause the actual results,
financial condition and liquidity, performance or achievements of
Galapagos, or industry results, to be materially different from any
historic or future results, financial conditions and liquidity,
performance or achievements expressed or implied by such forward-looking
statements. In addition, even if Galapagos’ results, performance,
financial condition and liquidity, and the development of the industry
in which it operates are consistent with such forward-looking
statements, they may not be predictive of results or developments in
future periods. Among the factors that may result in differences are the
inherent uncertainties associated with competitive developments,
clinical trial and product development activities and regulatory
approval requirements (including that data from the ongoing and planned
clinical research programs may not support registration or further
development of filgotinib due to safety, efficacy or other reasons),
Galapagos’ reliance on collaborations with third parties (including its
collaboration partner for filgotinib, Gilead), and estimating the
commercial potential of Galapagos’ product candidates. A further list
and description of these risks, uncertainties and other risks can be
found in Galapagos’ Securities and Exchange Commission (SEC) filings and
reports, including in Galapagos’ most recent annual report on form 20-F
filed with the SEC and subsequent filings and reports filed by Galapagos
with the SEC. Given these uncertainties, the reader is advised not to
place any undue reliance on such forward-looking statements. These
forward-looking statements speak only as of the date of publication of
this document. Galapagos expressly disclaims any obligation to update
any such forward-looking statements in this document to reflect any
change in its expectations with regard thereto or any change in events,
conditions or circumstances on which any such statement is based or that
may affect the likelihood that actual results will differ from those set
forth in the forward-looking statements, unless specifically required by
law or regulation.

Gilead Forward-Looking Statement

This press release includes forward-looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995 that are
subject to risks, uncertainties and other factors, including the
possibility that the final safety results from these studies differ
materially from those reported in this press release and the possibility
of unfavorable results from other clinical trials involving filgotinib.
Further, it is possible that the parties may make a strategic decision
to discontinue development of filgotinib, and as a result, filgotinib
may never be successfully commercialized. All statements other than
statements of historical fact are statements that could be deemed
forward-looking statements. These risks, uncertainties and other factors
could cause actual results to differ materially from those referred to
in the forward-looking statements. The reader is cautioned not to rely
on these forward-looking statements. These and other risks are described
in detail in Gilead’s Annual Report on Form 10-K for the year ended
December 31, 2018, as filed with the U.S. Securities and Exchange
