NEW YORK--(BUSINESS WIRE)--Pfizer Inc. announced today that more than 20 abstracts including new rheumatoid arthritis (RA) research for XELJANZ® (tofacitinib citrate) will be presented at the European League Against Rheumatism Annual Congress (EULAR 2015) June 10-15, Rome, Italy. Highlights include over six-years of safety and efficacy data from two long-term extension studies, real-world experience analyses, and clinical, patient-reported and radiographic efficacy outcomes with XELJANZ monotherapy, as well as health economics outcomes research that include patient-preference data for XELJANZ in patients with RA. Notably, new results from the XELJANZ 11 mg once daily clinical pharmacology program will be presented during the Congress, demonstrating equivalence in key pharmacokinetic parameters to XELJANZ 5 mg twice daily.
“As the developer of XELJANZ, the first oral Janus kinase inhibitor for the treatment of moderate to severe RA, Pfizer is a leader in the research of this new class of medications. Emerging real-world experience complements the clinical profile of XELJANZ as established through our extensive global development program,” said Rory O’Connor, MD, senior vice president and head of Global Medical Affairs, Global Innovative Pharmaceuticals Business, Pfizer Inc. “We continue to focus on further characterizing the overall clinical profile of XELJANZ that includes understanding the response of XELJANZ as monotherapy and by exploring a potential new once-daily formulation.”
These data — from clinical trials to real-world experience — further contextualize and expand the knowledge about the benefit:risk profile of XELJANZ in RA. XELJANZ is the first oral therapy in a new class of RA medicines, known as Janus kinase (JAK) inhibitors. Since the discovery of XELJANZ, the global clinical development program has accumulated efficacy and safety data with over six years of safety observations in long-term extension studies and more than 16,800 patient years of exposure across the program.
XELJANZ is approved in 40 countries for the treatment of moderate to severe RA as a second-line therapy after failure of one or more disease-modifying antirheumatic drugs (DMARDs). Pfizer is committed to making XELJANZ available to patients around the world, including working with the European Medicines Agency to plan to file a Marketing Authorization Application (MAA) in the European Union by the end of 2015 for the potential use of XELJANZ in treating moderate to severe RA. Pfizer is also committed to building on the science and understanding of JAK inhibition and XELJANZ with one of the largest clinical development programs in a range of immune-mediated inflammatory conditions in the areas of rheumatology, dermatology and gastroenterology.
The following abstracts, focused on further characterizing the efficacy and safety profile of XELJANZ, have been accepted for presentation at the European League Against Rheumatism Annual Congress (EULAR 2015):

XELJANZ® (tofacitinib citrate) 5 mg Tablets RA U.S. Label Information
XELJANZ is a prescription medicine called a Janus kinase (JAK) inhibitor. The recommended dose is 5 mg twice-daily (BID). 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.
- 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.
- 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 causes a range of symptoms, including stiffness and swelling in the joints,1,2 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 as 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 people worldwide.4 It can develop at any time during adulthood, but it usually occurs between 40 and 70 years of age.2
