FDA Advisory Committee Votes in Favor of Xeljanz® (Tofacitinib Citrate) for the Treatment of Active Psoriatic Arthritis

NEW YORK, August 3, 2017 – Pfizer Inc. announced today that the United States Food and Drug Administration’s (FDA) Arthritis Advisory Committee (AAC) voted 10 to 1 to recommend approval of the proposed dose of tofacitinib for the treatment of adult patients with active psoriatic arthritis (PsA). Pfizer submitted supplemental new drug applications (sNDAs) for XELJANZ® 5 mg twice daily (BID) and XELJANZ® XR extended release 11 mg once daily (QD) for this pending indication. The role of the Advisory Committee is to provide recommendations to the FDA. The FDA decision on whether to approve tofacitinib for PsA is anticipated by December 2017.

“Today marks an important positive step in our journey to potentially bring tofacitinib to adult patients living with active psoriatic arthritis and we are pleased with the Committee’s positive recommendation based on the favorable benefit:risk profile for tofacitinib,” said Michael Corbo, Chief Development Officer, Inflammation & Immunology, Pfizer Global Product Development. “If approved, tofacitinib would be the first Janus kinase (JAK) inhibitor for psoriatic arthritis. We look forward to working with the FDA to complete review of the applications.”

The AAC discussions were based on Pfizer’s applications for tofacitinib in PsA, which are currently under review by the FDA. These include data from the tofacitinib Phase 3 trials in PsA, as well as additional safety analyses from the broader tofacitinib clinical development program.

About Psoriatic Arthritis

Psoriatic arthritis (PsA) is a chronic, autoimmune, inflammatory disease that includes manifestations in peripheral joints, tendons, ligaments, bone and skin. PsA may include a variety of symptoms such as joint pain and stiffness, swollen toes and fingers, persistent painful tendonitis, irreversible joint damage and reduced range of motion. The disease usually appears between the ages of 30 to 50, equally between men and women, and can limit daily activities.

About Tofacitinib Citrate

Tofacitinib citrate is a Janus kinase (JAK) inhibitor. It is not currently approved for the treatment of PsA.

As the developer of tofacitinib, Pfizer is committed to advancing the science of JAK inhibition and enhancing understanding of tofacitinib through robust clinical development programs in the treatment of immune-mediated inflammatory conditions.

XELJANZ/XELJANZ XR U.S. Label Information

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

• It is not known if XELJANZ/XELJANZ XR is safe and effective in people with hepatitis B or C.
• XELJANZ/XELJANZ XR is not for people with severe liver problems.
• It is not known if XELJANZ/XELJANZ XR is safe and effective in children.

Important Safety Information

XELJANZ/XELJANZ XR can lower the ability of the immune system to fight infections. Some people can have serious infections while taking XELJANZ/XELJANZ XR, 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/XELJANZ XR, and monitor them closely for signs and symptoms of TB and other infections during treatment. People should not start taking XELJANZ/XELJANZ XR if they have any kind of infection unless their healthcare provider tells them it is okay.

People may be at a higher risk of developing shingles.
XELJANZ/XELJANZ XR may increase the risk of certain cancers by changing the way the immune system works. Lymphoma and other cancers, including skin cancers, can happen in patients taking XELJANZ/XELJANZ XR.

• The risks and benefits of treatment should be considered prior to initiating XELJANZ/XELJANZ XR 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/XELJANZ XR. Update immunizations in agreement with current immunization guidelines prior to initiating XELJANZ/XELJANZ XR 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/XELJANZ XR can 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/XELJANZ XR should be used with caution in patients who may be at increased risk for gastrointestinal perforation (e.g., patients with a history of diverticulitis), or who have a narrowing within their digestive tract.
• Some people taking XELJANZ have had 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/XELJANZ XR and while they are taking XELJANZ/XELJANZ XR, to check for these side effects. Normal cholesterol levels are important to good heart health. Healthcare providers may stop XELJANZ/XELJANZ XR treatment because of changes in blood cell counts or liver test results.
• Use of XELJANZ/XELJANZ XR 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/XELJANZ XR will harm an unborn baby. To monitor the outcomes of pregnant women exposed to XELJANZ/XELJANZ XR, 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/XELJANZ XR 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/XELJANZ XR. Healthcare providers may do blood tests before and during treatment with XELJANZ/XELJANZ XR.
• Common side effects of XELJANZ/XELJANZ XR include upper respiratory tract infections (common cold, sinus infections), headache, diarrhea, and nasal congestion, sore throat, and runny nose (nasopharyngitis).
