  Pfizer Provides Update on Global Regulatory Approvals and Launches of
  XELJANZ® (tofacitinib citrate) for the Treatment of Rheumatoid Arthritis

Business Wire

NEW YORK -- July 15, 2013

Pfizer Inc. (NYSE: PFE) announced today that tofacitinib has been approved for
the treatment of rheumatoid arthritis (RA) in patients who had an inadequate
response to existing therapies in several additional countries around the
world, including Switzerland, which is the first European country to receive
approval. Swissmedic, the Swiss agency for therapeutic products, approved
tofacitinib 5 and 10 mg twice-daily (BID) as monotherapy or in combination
with a disease modifying non-biologic antirheumatic agent (DMARD), including
methotrexate (MTX), in adult patients with moderate-to-severe active RA who
have had an inadequate response or intolerance to MTX. Tofacitinib 5 mg BID
has also been approved in Argentina, Kuwait and the United Arab Emirates, and
tofacitinib 5 mg and 10 mg BID has been approved in Russia. The brand name for
tofacitinib in the approved markets will be XELJANZ, except for Russia, where
the brand name will be Jaquinus^®.

As previously announced, XELJANZ 5 mg BID is also approved in the United
States and Japan for the treatment of moderate-to-severe active RA. XELJANZ
was launched in the United States in November 2012, and XELJANZ is expected to
be commercially available in Japan this month following approval by the
Japanese Ministry of Health, Labor and Welfare (MHLW) in March 2013. XELJANZ
will be co-promoted in Japan by Pfizer and Takeda Pharmaceutical Company
Limited. Initially, XELJANZ will be made available in Japan to medical
institutions participating in an all-patient surveillance program, designed by
Pfizer in collaboration with Japan’s Pharmaceuticals and Medical Devices
Agency (PMDA) and the Japan College of Rheumatology.

“More than 23 million people worldwide are living with rheumatoid arthritis
and there remains an unmet need for additional treatments, with up to
one-third of RA patients not adequately responding and about half who stop
responding to any particular DMARD within five years,” said Geno Germano,
president and general manager, Specialty Care and Oncology, Pfizer. “XELJANZ
has a novel mechanism of action for the treatment of moderate-to-severe RA.
With these approvals, we believe XELJANZ has the potential to change the way
rheumatologists treat this chronic, and potentially disabling, disease, and we
are proud to offer patients and physicians an additional treatment option.”

Regulatory applications for XELJANZ for the treatment of moderate-to-severe
active RA remain under review in more than 30 additional countries. In Europe,
Pfizer is seeking a re-examination of the Committee for Medicinal Products for
Human Use (CHMP) negative opinion that was announced in April, and the company
is currently working with the CHMP on the next steps in the process.

XELJANZ is the first approved RA treatment in a new class of medicines known
as Janus kinase (JAK) inhibitors. The recent marketing authorizations for
XELJANZ were based on data from the comprehensive, global, multi-study
clinical development program for XELJANZ, which included approximately 5,000
patients in more than 40 countries, resulting in 7,000 patient-years of
experience at the time of regulatory submission.

Important Safety Findings for XELJANZ

Notable safety findings observed in the XELJANZ RA program include serious and
other important infections, including tuberculosis and herpes zoster;
malignancies, including lymphoma; gastrointestinal perforations; decreased
neutrophil and lymphocyte counts; and lipid elevations. The most common
serious adverse events were serious infections. The most commonly reported
adverse events were upper respiratory tract infections, headache,
nasopharyngitis and diarrhea.

About Rheumatoid Arthritis

Rheumatoid arthritis is a chronic inflammatory autoimmune disease that
typically affects the hands and feet, although any joint lined by a synovial
membrane may be affected. RA can be painful and disabling,^1 causing swelling,
stiffness and loss of function in the joints.^1 RA affects 23.7 million people
worldwide,^2 and although multiple treatments are available, up to one-third
of patients do not adequately respond, and about half stop responding to any
particular DMARD within five years.^3,4,5,6,7,8 As a result, there remains a
need for additional options.

About XELJANZ

XELJANZ is a novel, oral Janus kinase (JAK) inhibitor for the treatment of RA.
Unlike recent therapies for RA, which are directed at extracellular targets
such as pro-inflammatory cytokines, XELJANZ takes a novel approach targeting
the intracellular pathways that operate as hubs in the inflammatory cytokine
network.
