Pfizer Announces Over 10 Abstracts for XELJANZ® (Tofacitinib Citrate) in Rheumatoid Arthritis to be Presented at the European League Against Rheumatism (EULAR) 2014 Annual Meeting

Additional Data Further Characterizes the Safety Profile of XELJANZ

NEW YORK--(BUSINESS WIRE)--Pfizer Inc. announced today that over 10 abstracts have been accepted for presentation at the European League Against Rheumatism (EULAR) 2014 Annual Meeting (June 11-14, Paris, France), seven of which are focused on further characterizing the safety profile of XELJANZ (tofacitinib citrate) in treating moderately to severely active rheumatoid arthritis. Notably, an abstract titled, "Integrated safety analysis of tofacitinib in rheumatoid arthritis clinical trials with a cumulative exposure of 12,664 patient-years," will be presented as an oral abstract session (OP0154) on June 13, 2014 at 11:30 a.m. CEST. This analysis describes safety data for XELJANZ in patients from the integrated rheumatoid arthritis clinical trial database, which is based on cumulative exposure in Phase 2, Phase 3, and open-label long-term extension studies. The analysis includes 5,671 patients with a median exposure of 2.4 years including more than 500 patients followed for greater than four years.

"Pfizer is proud to showcase our commitment to the ongoing study of XELJANZ, with a focus on further establishing its benefit:risk profile in rheumatoid arthritis, a disease which affects more than 23 million people worldwide," said Dr. Steven Romano, Global Medicines Development Lead for the Pfizer Global Innovative Pharmaceutical business.

XELJANZ is now approved in more than 20 countries for the treatment of patients with moderately to severely active rheumatoid arthritis who had an inadequate response to existing therapies. Most recently, Health Canada approved XELJANZ 5 mg twice daily in combination with methotrexate for reducing the signs and symptoms of rheumatoid arthritis in adult patients with moderately to severely active rheumatoid arthritis who have had an inadequate response or intolerance to methotrexate. In cases of intolerance to methotrexate, physicians may consider the use of XELJANZ as monotherapy. Regulatory applications for XELJANZ for the treatment of moderately to severely active rheumatoid arthritis remain under review in more than 35 additional countries. In Europe, XELJANZ is approved in Russia, Switzerland and Turkey, and Pfizer is working on next steps to re-file an application with the European Medicines Agency (EMA).

The following additional abstracts focused on further characterizing the efficacy and safety profile of XELJANZ have also been accepted for presentation at the EULAR 2014 Annual Meeting:

XELJANZ® (tofacitinib citrate) 5 mg Tablets RA U.S. Label Information

XELJANZ is a prescription medicine called a Janus kinase (JAK) inhibitor. XELJANZ is used to treat adults with moderately to severely active rheumatoid arthritis in which methotrexate did not work well. XELJANZ may be used as a single agent or in combination with MTX or other non-biologic disease-modifying antirheumatic drugs (DMARDs). Use of XELJANZ in combination with biologic DMARDs or potent immunosuppressants, such as azathioprine and cyclosporine is not recommended. The recommended dose is 5 mg twice-daily (BID).

It is not known if XELJANZ is safe and effective in people with Hepatitis B or C.
XELJANZ is not for people with severe liver problems.
It is not known if XELJANZ is safe and effective in children.
Important Safety Information

XELJANZ can lower the ability of the immune system to fight infections. Some people have serious infections while taking XELJANZ, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections. Healthcare providers should test patients for TB before starting XELJANZ, and monitor them closely for signs and symptoms of TB and other infections during treatment. People should not start taking XELJANZ if they have any kind of infection unless their healthcare provider tells them it is okay.
XELJANZ may increase the risk of certain cancers by changing the way the immune system works. Malignancies were observed in clinical studies of XELJANZ.
The risks and benefits of treatment should be considered prior to initiating XELJANZ in patients with chronic or recurrent infection; who have been exposed to tuberculosis; with a history of a serious or an opportunistic infection; who have resided or traveled in areas of endemic tuberculosis or endemic mycoses; or with underlying conditions that may predispose them to infection.
Viral reactivation, including cases of herpes virus reactivation (e.g., herpes zoster), was observed in clinical studies with XELJANZ.
Use of live vaccines should be avoided concurrently with XELJANZ. Update immunizations in agreement with current immunization guidelines prior to initiating XELJANZ therapy.
Some people who have taken XELJANZ with certain other medicines to prevent kidney transplant rejection have had a problem with certain white blood cells growing out of control (Epstein Barr virus-associated post-transplant lymphoproliferative disorder).
Some people taking XELJANZ get tears in their stomach or intestines. This happens most often in people who also take nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or methotrexate. Patients should tell their healthcare provider right away if they have fever and stomach-area pain that does not go away, or a change in bowel habits. XELJANZ should be used with caution in patients who may be at increased risk for gastrointestinal perforation (e.g., patients with a history of diverticulitis).
XELJANZ can cause changes in certain lab test results including low blood cell counts, increases in certain liver tests, and increases in cholesterol levels. Healthcare providers should do blood tests before starting patients on XELJANZ and while they are taking XELJANZ, to check for these side effects. Normal cholesterol levels are important to good heart health. Healthcare providers may stop XELJANZ treatment because of changes in blood cell counts or liver test results.
Use of XELJANZ in patients with severe hepatic impairment is not recommended.
Patients should tell their healthcare providers if they plan to become pregnant or are pregnant.
It is not known if XELJANZ will harm an unborn baby. To monitor the outcomes of pregnant women exposed to XELJANZ, a registry has been established. Physicians are encouraged to register patients and pregnant women are encouraged to register themselves by calling 1-877-311-8972.

Patients should tell their healthcare providers if they plan to breastfeed or are breastfeeding. Patients and their healthcare provider should decide if they will take XELJANZ or breastfeed. They should not do both. [BEGIN TEXT BOX]

In carriers of the hepatitis B or C virus (viruses that affect the liver), the virus may become active while using XELJANZ. Healthcare providers may do blood tests before and during treatment with XELJANZ.
Common side effects include upper respiratory tract infections (common cold, sinus infections), headache, diarrhea, and nasal congestion, sore throat, and runny nose (nasopharyngitis).

About Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic, inflammatory autoimmune disease that typically affects the hands and feet, although any joint lined by the synovial membrane can be affected.1 RA causes a range of symptoms, including stiffness and swelling in the joints,2 particularly those in the hands, feet and knees.1 Although the exact cause of RA is unknown,1 it is considered to be an autoimmune disease, because the immune system in people with RA mistakes the body's healthy tissues for a threat and attacks them.1 Some people are at increased risk of developing RA, including people with a family history of RA, smokers and women.3 Three times as many women are affected by RA compared to men.2 RA affects approximately 23.7 million people4 worldwide and 1.6 million people in the United States.5,6 It can develop at any time during adulthood, but it usually occurs between 40 and 70 years of age.2
