Brussels (Belgium), 8th November 2022 (18:00 CET) =E2=80=93 UCB, a global b=
iopharmaceutical company, today announced that it will present 15 abstracts=
across its rheumatology portfolio at ACR Convergence 2022 to be held in Ph=
iladelphia, November 10=E2=80=9314, 2022. The abstracts, including two with=
late-breaking data, have been accepted as four oral presentations, eight e=
-posters, and three =E2=80=98Ignite Talks=E2=80=99 which are five-minute in=
-person presentations focused on the highest ranked posters at the meeting.=

=E2=80=9CThe breadth of new data we are presenting at ACR Convergence 2022,=
including the first presentation of bimekizumab 52-week data in psoriatic =
arthritis, ankylosing spondylitis and non-radiographic axial spondyloarthri=
tis, underscore our commitment to address unmet patient needs and to raise =
standards of care,=E2=80=9D said Emmanuel Caeymaex, Executive Vice Presiden=
t, Immunology Solutions and Head of U.S., UCB.=C2=A0

UCB is investigating bimekizumab in psoriatic arthritis (PsA), non-radiogra=
phic axial spondyloarthritis (nr-axSpA) and ankylosing spondylitis (AS) als=
o known as radiographic axSpA. The efficacy and safety of bimekizumab in Ps=
A, nr-axSpA and AS have not been established, and it is not approved for us=
e in these indications by any regulatory authority worldwide.

Bimekizumab data highlights

Data evaluating bimekizumab in the treatment of PsA and across the spectrum=
of axSpA will be shared across three oral presentations, three =E2=80=98Ig=
nite Talks=E2=80=99 and six e-posters.

One oral presentation and one =E2=80=98Ignite Talk=E2=80=99 will detail lat=
e-breaking 52-week data from the bimekizumab studies. The oral presentation=
will present results from the Phase 3 BE OPTIMAL study evaluating bimekizu=

About CIMZIA^=C2=AE in the U.S.^5

CIMZIA^=C2=AE is the only Fc-free, PEGylated anti-TNF (Tumor Necrosis Facto=
r). CIMZIA has a high affinity for human TNF-alpha, selectively neutralizin=
g the pathophysiological effects of TNF-alpha.=C2=A0

CIMZIA is also indicated for the treatment of adults with moderately to sev=
erely active rheumatoid arthritis (RA), adults with active psoriatic arthri=
tis (PsA), adults with active ankylosing spondylitis (AS), and adults with =
active non-radiographic axial spondyloarthritis (nr-axSpA) with objective s=
igns of inflammation.

CIMZIA is indicated for the treatment of moderate to severe plaque psoriasi=
s (PSO) in adults who are candidates for systemic therapy or phototherapy.=

In addition, CIMZIA is indicated for reducing signs and symptoms of Crohn's=
disease (CD) and maintaining clinical response in adult patients with mode=
rately to severely active disease who have had an inadequate response to co=
nventional therapy. See important safety information including risk of seri=
ous bacterial, viral and fungal infections and tuberculosis below.



CIMZIA is contraindicated in patients with a history of hypersensitivity re=
action to certolizumab pegol or to any of the excipients. Reactions have in=
cluded angioedema, anaphylaxis, serum sickness, and urticaria.


Patients treated with CIMZIA are at increased risk for developing serious i=
nfections that may lead to hospitalization or death. Most patients who deve=
loped these infections were taking concomitant immunosuppressants such as m=
ethotrexate or corticosteroids.=C2=A0

Discontinue CIMZIA if a patient develops a serious infection or sepsis.

Reported infections include:

=C2=B7 Active tuberculosis (TB), including reactivation of latent TB. Patie=
nts with TB have frequently presented with disseminated or extrapulmonary d=
isease. Test patients for latent TB before CIMZIA use and during therapy. I=
nitiate treatment for latent TB prior to CIMZIA use.
=C2=B7 Invasive fungal infections, including histoplasmosis, coccidioidomyc=
osis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patien=
ts with histoplasmosis or other invasive fungal infections may present with=
disseminated, rather than localized, disease. Antigen and antibody testing=
for histoplasmosis may be negative in some patients with active infection.=
Consider empiric anti-fungal therapy in patients at risk for invasive fung=
al infections who develop severe systemic illness.
=C2=B7 Bacterial, viral, and other infections due to opportunistic pathogen=
s, including Legionella and Listeria.=C2=A0

Carefully consider the risks and benefits of treatment with CIMZIA prior to=
initiating therapy in the following patients: with chronic or recurrent in=
fection; who have been exposed to TB; =C2=A0with a history of opportunistic=
infection; who resided in or traveled in regions where mycoses are endemic=
; with underlying conditions that may predispose them to infection. Monitor=
patients closely for the development of signs and symptoms of infection du=
ring and after treatment with CIMZIA, including the possible development of=
TB in patients who tested negative for latent TB infection prior to initia=
ting therapy.

=C2=B7 Do not start CIMZIA during an active infection, including localized =
=C2=B7 Patients older than 65 years, patients with co-morbid conditions, an=
d/or patients taking concomitant immunosuppressants may be at greater risk =
of infection.
=C2=B7 If an infection develops, monitor carefully and initiate appropriate=


Lymphoma and other malignancies, some fatal, have been reported in children=
and adolescent patients treated with TNF blockers, of which CIMZIA is a me=
mber. CIMZIA is not indicated for use in pediatric patients.

=C2=B7 Consider the risks and benefits of CIMZIA treatment prior to initiat=
ing or continuing therapy in a patient with known malignancy.
=C2=B7 In clinical trials, more cases of malignancies were observed among C=
IMZIA-treated patients compared to control patients.
=C2=B7 In CIMZIA clinical trials, there was an approximately 2-fold higher =
rate of lymphoma than expected in the general U.S. population. Patients wit=
h rheumatoid arthritis, particularly those with highly active disease, are =
at a higher risk of lymphoma than the general population.
=C2=B7 Malignancies, some fatal, have been reported among children, adolesc=
ents, and young adults being treated with TNF blockers. Approximately half =
of the cases were lymphoma, while the rest were other types of malignancies=
, including rare types associated with immunosuppression and malignancies n=
ot usually seen in this patient population.
=C2=B7 Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare=
type of T-cell lymphoma, have been reported in patients treated with TNF b=
lockers, including CIMZIA. These cases have had a very aggressive disease c=
ourse and have been fatal. The majority of reported TNF blocker cases have =
occurred in patients with Crohn's disease or ulcerative colitis, and the ma=
jority were in adolescent and young adult males. Almost all of these patien=
ts had received treatment with azathioprine or 6-mercaptopurine concomitant=
ly with a TNF blocker at or prior to diagnosis. Carefully assess the risks =
and benefits of treating with CIMZIA in these patient types.
=C2=B7 Cases of acute and chronic leukemia were reported with TNF blocker u=


=C2=B7 Worsening and new onset congestive heart failure (CHF) has been repo=
rted with TNF blockers. Exercise caution and monitor carefully.


=C2=B7 Angioedema, anaphylaxis, dyspnea, hypotension, rash, serum sickness,=
and urticaria have been reported following CIMZIA administration. If a ser=
ious allergic reaction occurs, stop CIMZIA and institute appropriate therap=
y. The needle shield inside the removable cap of the CIMZIA prefilled syrin=
ge contains a plastic derivative of natural rubber latex which may cause an=
allergic reaction in individuals sensitive to latex.


=C2=B7 Use of TNF blockers, including CIMZIA, may increase the risk of reac=
tivation of hepatitis B virus (HBV) in patients who are chronic carriers. S=
ome cases have been fatal.
=C2=B7 Test patients for HBV infection before initiating treatment with CIM=
=C2=B7 Exercise caution in patients who are carriers of HBV and monitor the=
m before and during CIMZIA treatment.
=C2=B7 Discontinue CIMZIA and begin antiviral therapy in patients who devel=
op HBV reactivation. Exercise caution when resuming CIMZIA after HBV treatm=


=C2=B7 TNF blockers, including CIMZIA, have been associated with rare cases=
of new onset or exacerbation of central nervous system and peripheral demy=
elinating diseases, including multiple sclerosis, seizure disorder, optic n=
euritis, peripheral neuropathy, and Guillain-Barr=C3=A9 syndrome.


=C2=B7 Rare reports of pancytopenia, including aplastic anemia, have been r=
eported with TNF blockers. Medically significant cytopenia has been infrequ=
ently reported with CIMZIA.
=C2=B7 Consider stopping CIMZIA if significant hematologic abnormalities oc=


=C2=B7 Do not use CIMZIA in combination with other biological DMARDS.


=C2=B7 Treatment with CIMZIA may result in the formation of autoantibodies =
and, rarely, in development of a lupus-like syndrome. Discontinue treatment=
if symptoms of a lupus-like syndrome develop.


=C2=B7 Patients on CIMZIA should not receive live or live-attenuated vaccin=


=C2=B7 The most common adverse reactions in CIMZIA clinical trials (=E2=89=
=A58%) were: upper respiratory infections (18%), rash (9%), and urinary tra=
ct infections (8%).

About certolizumab pegol in the EU/EEA^6

In the EU, CIMZIA^=C2=AE (certolizumab pegol) in combination with methotrex=
ate (MTX) is indicated for the treatment of moderate to severe active RA in=
adult patients when the response to disease-modifying antirheumatic drugs =
(DMARDs) including MTX, has been inadequate. Certolizumab pegol can be give=
n as monotherapy in case of intolerance to MTX or when continued treatment =
with MTX is inappropriate. Certolizumab pegol in combination with MTX is al=
so indicated for the treatment of severe, active and progressive RA in adul=
ts not previously treated with MTX or other DMARDs. Certolizumab pegol has =
been shown to reduce the rate of progression of joint damage as measured by=
X-ray and to improve physical function, when given in combination with MTX=

Certolizumab pegol, in combination with MTX, is also indicated for the trea=
tment of active psoriatic arthritis in adults when the response to previous=
DMARD therapy has been inadequate. Certolizumab pegol can be given as mono=
therapy in case of intolerance to MTX or when continued treatment with MTX =
is inappropriate.

Certolizumab pegol is also indicated in the EU for the treatment of adult p=
atients with severe active axial spondyloarthritis (axSpA), comprising:=C2=

=C2=B7 Ankylosing spondylitis (AS) =E2=80=93 adults with severe active AS w=
ho have had an inadequate response to, or are intolerant to non-steroidal a=

=C2=B7 Axial spondyloarthritis (axSpA) without radiographic evidence of AS =
=E2=80=93 adults with severe active axSpA without radiographic evidence of =
AS but with objective signs of inflammation by elevated C-reactive protein =
(CRP) and/or Magnetic Resonance Imaging (MRI) who have had an inadequate re=
sponse to, or are intolerant to NSAIDs.

Certolizumab pegol is also indicated for the treatment of moderate to sever=
e plaque psoriasis in adults who are candidates for systemic therapy.=C2=A0

Cimzia^=C2=AE (certolizumab pegol) EU/EEA Important Safety Information^6

Cimzia^=C2=AE was studied in 4,049 patients with rheumatoid arthritis (RA) =
in controlled and open label trials for up to 92 months. The commonly repor=
ted adverse reactions (1-10%) in clinical trials with certolizumab pegol an=
d post-marketing were viral infections (includes herpes =C2=A0zoster, papil=
lomavirus, influenza), bacterial infections (including abscess), rash, head=
ache =C2=A0(including migraine), asthenia, leukopenia (including lymphopeni=
a, neutropenia), eosinophilic disorder, pain (any sites), pyrexia, sensory =
abnormalities, hypertension, =C2=A0pruritus (any sites), hepatitis (includi=
ng hepatic enzyme increase), injection site reactions, and nausea. Serious =
adverse reactions include sepsis, opportunistic infections, tuberculosis (i=
ncluding miliary, disseminated and extrapulmonary), herpes zoster, lymphoma=
, leukaemia, solid organ tumours, angioneurotic oedema, cardiomyopathies (i=
ncludes heart failure), ischemic coronary artery disorders, pancytopenia, h=
ypercoagulation (including thrombophlebitis, pulmonary embolism), cerebrova=
scular accident, vasculitis, hepatitis/hepatopathy (includes cirrhosis), an=
d renal impairment/nephropathy (includes nephritis). In RA controlled clini=
cal trials, 4.4% of patients discontinued taking certolizumab pegol due to =
adverse events vs. 2.7% for placebo.

Certolizumab pegol was initially studied in 325 patients with active axial =
spondyloarthritis (including ankylosing spondylitis and non-radiographic ax=
ial spondyloarthritis) in the AS001 clinical study for up to 4 years, which=
includes a 24-week placebo-controlled phase followed by a 24-week dose-bli=
nd period and a 156-week open-label treatment period. Certolizumab pegol wa=
s subsequently studied in 317 patients with non-radiographic axial spondylo=
arthritis in a placebo-controlled study for 52 weeks (AS0006). Certolizumab=
pegol was also studied in patients with axial spondyloarthritis (including=
ankylosing spondylitis and non-radiographic axial spondyloarthritis) in a =
clinical study for up to 96 weeks, which included a 48-week open-label run-=
in phase (N=3D736) followed by a 48-week placebo-controlled phase (N=3D313)=
for patients in sustained remission (C-OPTIMISE). Certolizumab pegol was a=
lso studied in a 96-week open-label study in 89 axSpA patients with a histo=
ry of documented anterior uveitis flares. In all 4 studies, the safety prof=
ile for these patients was consistent with the safety profile in rheumatoid=
arthritis and previous experience with certolizumab pegol.

Certolizumab pegol was studied in 409 patients with psoriatic arthritis (Ps=
A) in a clinical study for up to 4 years which included a 24-week placebo-c=
ontrolled phase followed by a 24-week dose-blind period and a 168-week open=
-label treatment period.=C2=A0

The safety profile for axSpA and PsA patients treated with certolizumab peg=
ol was consistent with the safety profile in RA and previous experience wit=
h certolizumab pegol.

Certolizumab pegol was studied in 1112 patients with psoriasis in controlle=
d and open-label studies for up to 3 years. In the Phase III program, the i=
nitial and maintenance periods were followed by a 96-week open-label treatm=
ent period. The long-term safety profile of certolizumab pegol 400 mg every=
2 weeks and certolizumab pegol 200 mg every 2 weeks was generally similar =
and consistent with previous experience with certolizumab pegol.

Certolizumab pegol is contraindicated in patients with hypersensitivity to =
the active substance or any of the excipients, active tuberculosis or other=
severe infections such as sepsis or opportunistic infections, and moderate=
to severe heart failure.

Serious infections including sepsis, tuberculosis and opportunistic infecti=
ons (e.g. histoplasmosis, nocardia, candidiasis) have been reported in pati=
ents receiving certolizumab pegol. Some of these events have been fatal. Be=
fore initiation of therapy with certolizumab pegol, all patients must be ev=
aluated for both active and inactive (latent) tuberculosis infection. If ac=
tive tuberculosis is diagnosed prior to or during treatment, certolizumab p=
egol therapy must not be initiated and must be discontinued. If latent tube=
rculosis is diagnosed, appropriate anti- tuberculosis therapy must be start=
ed before initiating treatment with certolizumab pegol.=C2=A0

Reactivation of hepatitis B has occurred in patients receiving a TNF-antago=
nist including certolizumab pegol who are chronic carriers of the virus (i.=
e. surface antigen positive). Some cases have had a fatal outcome. Patients=
should be tested for HBV infection before initiating treatment with certol=
izumab pegol. Carriers of HBV who require treatment with certolizumab pegol=
should be closely monitored and in the case of HBV reactivation Certolizum=
ab pegol should be stopped and effective anti-viral therapy with appropriat=
e supportive treatment should be initiated.

TNF antagonists including certolizumab pegol may increase the risk of new o=
nset or exacerbation of clinical symptoms and/or radiographic evidence of d=
emyelinating disease including multiple sclerosis; of formation of autoanti=
bodies and uncommonly of the development of a lupus-like syndrome; of sever=
e hypersensitivity reactions. If a patient develops any of these adverse re=
actions, certolizumab pegol should be discontinued and appropriate therapy =

With the current knowledge, a possible risk for the development of lymphoma=
s, leukaemia or other malignancies in patients treated with a TNF antagonis=
t cannot be excluded. Rare cases of neurological disorders, including seizu=
re disorder, neuritis and peripheral neuropathy, have been reported in pati=
ents treated with certolizumab pegol.

Adverse reactions of the haematologic system, including medically significa=
nt cytopenia, have been reported with certolizumab pegol. Advise all patien=
ts to seek immediate medical attention if they develop signs and symptoms s=
uggestive of blood dyscrasias or infection (e.g., persistent fever, bruisin=
g, bleeding, pallor) while on certolizumab pegol. Consider discontinuation =
of certolizumab pegol therapy in patients with confirmed significant haemat=
ological abnormalities.

The use of certolizumab pegol in combination with anakinra or abatacept is =
not recommended due to a potential increased risk of serious infections. As=
no data are available, certolizumab pegol should not be administered concu=
rrently with live vaccines. The 14-day half-life of certolizumab pegol shou=
ld be taken into consideration if a surgical procedure is planned. A patien=
t who requires surgery while on certolizumab pegol should be closely monito=
red for infections.

Bimekizumab is a humanized monoclonal IgG1 antibody that is designed to sel=
ectively inhibit both interleukin 17A (IL-17A) and interleukin 17F (IL-17F)=
, two key cytokines driving inflammatory processes.^7,8=C2=A0 In August 202=
1, bimekizumab was approved in the European Union (EU)/European Economic Ar=
ea (EEA) and in Great Britain, for the treatment of moderate to severe plaq=
ue psoriasis in adults who are candidates for systemic therapy.^8,9=C2=A0Th=
e label information may differ in other countries. Please check local presc=
ribing information. In the U.S., the efficacy and safety of bimekizumab hav=
e not been established for any indication and it is not approved by the U.S=
. Food and Drug Administration (FDA).
