Pfizer Announces Data For XELJANZ®(tofacitinib citrate) In Rheumatoid Arthritis To Be Presented At The American College Of Rheumatology 2013 Annual Meeting

Long-Term Safety and Efficacy Data of XELJANZ Up to Five Years Will Be Presented

NEW YORK--(BUSINESS WIRE)-- Pfizer Inc. (NYS: PFE) announced today that 20 abstracts for XELJANZ® (tofacitinib citrate), the first in a new class for the treatment of rheumatoid arthritis (RA), oral Janus kinase (JAK) inhibitors, will be presented at the American College of Rheumatology (ACR) / Association of Rheumatology Health Professionals (ARHP) 2013 Annual Meeting, which is being held October 25-30 in San Diego, CA. XELJANZ is approved in the United States for the treatment of adults with moderately to severely active RA who have had an inadequate response or intolerance to methotrexate, at a dose of 5 mg tablet twice daily.


These data add to the understanding of the efficacy and safety profile of XELJANZ in the treatment of RA. XELJANZ was studied in a comprehensive, global, multi-study program that included approximately 5,000 patients across Phase 2 and 3 trials in more than 40 countries, resulting in 7,000 patient-years of exposure through 2011, the time of regulatory submission. These data further inform rheumatologists who are prescribing or considering prescribing XELJANZ for appropriate patients.

Among the analyses being presented are open-label safety and efficacy data up to five years in long-term extension (LTE) studies; integrated and post-hoc analyses of safety data; and post-hoc safety and efficacy analyses of clinical trial sub-populations, notably one that analyzed the safety profile and efficacy of XELJANZ in U.S. patients versus patients from the Rest of World (ROW). More details on these abstracts are found below.

LTE Safety and Efficacy Data Up to Five Years

Tofacitinib, an Oral Janus Kinase Inhibitor, in the Treatment of Rheumatoid Arthritis: Open Label, Long-Term Extension Safety and Efficacy Up To 5 Years

Data from a pooled analysis of two open-label LTE studies (global A3921024 ORAL Sequel Study and Japan A3921041 Study) involving patients with moderately to severely active RA who had participated in randomized Phase 2 or 3 studies of XELJANZ dosed at 5 or 10 mg BID.

  • Analysis showed a consistent safety profile and sustained efficacy for XELJANZ over time up to five years in LTE.

  • Primary endpoints were adverse events and confirmed laboratory safety data.

Post-Hoc Analysis Of Risk Factors for Serious Infection Events (SIE)

Post-Hoc Analysis Of Serious Infection Events and Selected Clinical Factors In Rheumatoid Arthritis Patients Treated With Tofacitinib

Data from a pooled analysis of five randomized Phase 2 studies, five randomized Phase 3 studies and two open-label LTE studies involving patients with moderately to severely active RA who had received XELJANZ dosed at 5 or 10 mg BID were analyzed to determine risk factors for SIEs.

  • Consistent with reports from multiple RA patient databases, analysis identified age (elderly); diabetes; prednisone and corticosteroid equivalent dose ≥7.5 mg as independent factors associated with an increased risk of SIEs.

  • Tofacitinib dose was also identified as an independent risk factor for SIEs.

Integrated Safety Analysis Of Malignancies

Tofacitinib, An Oral Janus Kinase Inhibitor: Analysis Of Malignancies Across The Rheumatoid Arthritis Clinical Program

Data from a pooled analysis of six randomized Phase 2 studies, six randomized Phase 3 studies and two open-label LTE studies involving patients with moderately to severely active RA who had received XELJANZ dosed at 5 or 10 mg BID were analyzed with regards to malignancies.

  • Analysis showed that the malignancies that occurred are consistent with the type and distribution of malignancies expected for patients with moderately to severely active RA and rates are consistent with published estimates in RA patients treated with biologic and non-biologic DMARDs.

Safety and Efficacy of XELJANZ in U.S. Versus ROW Study Populations

Efficacy and Safety Analyses Of Tofacitinib From Pooled Phase 2, Phase 3 and Long-Term Extension Rheumatoid Arthritis Studies: U.S. Compared With Non-U.S. Populations

Pooled data from DMARD-inadequate responder patients with moderately to severely active RA in six Phase 2 and five Phase 3 randomized studies and two open-label LTE studies who received XELJANZ dosed at 5 or 10 mg BID were analyzed to determine whether there were any differences in efficacy and/or safety between the U.S. and ROW populations.

  • Analyses showed numerical differences with higher rates for tuberculosis, herpes zoster and lymphoma in ROW compared with the U.S. but higher rates of serious infection events, malignancies and deaths in the U.S.

  • Efficacy in general was similar between populations studied.

  • Conclusions are limited by the difference in population sizes.

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. Lymphoma and other cancer can happen in patients taking XELJANZ.

  • Some people taking XELJANZ get tears in their stomach or intestines. 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 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.

  • 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.

  • 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 for hepatitis before and during treatment with XELJANZ.

  • Common side effects include upper respiratory tract infections (common cold, sinus infections), headache, diarrhea, nasal congestion, sore throat, and runny nose (nasopharyngitis).

About XELJANZ

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.

  • 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.

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 1.6 million Americans1,2 and 23.7 million people worldwide.3 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.4,5,6,7,8,9 There remains a need for additional therapeutic options.
