CHMP Confirms Prior Opinion Regarding Marketing Authorization in Europe for Pfizer’s XELJANZ® (tofacitinib citrate)



  CHMP Confirms Prior Opinion Regarding Marketing Authorization in Europe for
  Pfizer’s XELJANZ® (tofacitinib citrate)

  Pfizer Plans to Work with the European Medicines Agency (EMA) to Resubmit
                  Marketing Authorization Application (MAA)

Business Wire

NEW YORK -- July 25, 2013

Pfizer Inc. (NYSE: PFE) announced today that the Committee for Medicinal
Products for Human Use (CHMP) of the European Medicines Agency (EMA) has
confirmed its April 25, 2013, opinion to recommend against approval of
XELJANZ^® (tofacitinib citrate) for the treatment of adult patients with
moderate-to-severe active rheumatoid arthritis (RA). After re-examination of
the application as requested by Pfizer, the CHMP is of the opinion that
XELJANZ does not demonstrate a favorable benefit:risk profile.

While the CHMP considered that treatment with XELJANZ resulted in reduction in
the signs and symptoms of RA and improvement in the physical function of
patients, it has outstanding concerns on safety, including serious infections.

The Company is currently evaluating the feedback from the CHMP and will
determine next steps to resubmit a MAA to the EMA.

“We are disappointed in the outcome of the re-examination process. A narrow
majority of the CHMP felt there is too limited experience in the patient
population to fully characterize the profile of XELJANZ and the Committee did
not recommend approval at this time,” said Dr. Steven Romano, senior vice
president and the head of the Medicines Development Group for Pfizer Specialty
Care. “The clinical experience with XELJANZ to date, which includes data from
approximately 5,000 patients treated for RA, demonstrates a consistent
efficacy and safety profile across a range of patient types and a risk profile
that is familiar to rheumatologists who have experience utilizing the range of
treatments available to treat this disease. We believe that the benefit:risk
profile of XELJANZ is favorable, and we remain committed to working with the
EMA to make XELJANZ available to appropriate patients in Europe.”

About the Marketing Authorization Application

The MAA included data from the comprehensive, global, multi-study clinical
development program for XELJANZ, which included approximately 5,000 patients
across Phase 2 and Phase 3 trials in more than 40 countries, resulting in
7,000 patient-years of exposure at the time of regulatory submission. The
application was based on the same pivotal efficacy and safety data package
that was provided to regulatory agencies around the world.

About Rheumatoid Arthritis

RA 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 affects approximately 23.7 million people worldwide and 6.2
million in Europe.^1 Although multiple treatments are available, many patients
do not adequately respond. Specifically, up to one-third of patients do not
adequately respond and about half stop responding to any particular
non-biologic disease-modifying antirheumatic drug (DMARD) within five
years.^2,3,4,5,6,7 There remains a need for additional therapeutic 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.

XELJANZ is approved in the United States, Japan, Argentina, Kuwait, Russia,
Switzerland and the United Arab Emirates for the treatment of adults with
moderate-to-severe active RA.
