Pfizer Announces U.S. FDA Filing Acceptance of Supplemental New Drug Application for XELJANZ ® (tofacitinib citrate) for the Treatment of Adult Patients with Active Psoriatic Arthritis
Pfizer Inc. announced today that the United States Food and Drug Administration (FDA) has accepted for review the supplemental
New Drug Application (sNDA) for XELJANZ® (tofacitinib citrate) 5 mg twice daily (BID) for the treatment of adult
patients with active psoriatic arthritis (PsA). A separate sNDA was also accepted for XELJANZ XR® (tofacitinib citrate)
extended release 11 mg once daily use in PsA. The sNDA submission is based on data from the Phase 3 Oral Psoriatic
Arthritis TriaLs (OPAL) clinical development program, which consisted of two pivotal trials and a long-term extension
study, evaluating the safety and efficacy of XELJANZ in patients with active PsA who had failed prior PsA treatments. The FDA has
provided an anticipated Prescription Drug User Fee Act (PDUFA) action date in December 2017 for the sNDAs.
“Psoriatic arthritis is a complex disease involving joint inflammation and damage, psoriasis, and musculoskeletal inflammation,
which may limit physical functioning for people living with the disease. Despite advances in the treatment of psoriatic arthritis
in recent years, many people are still living with active disease and are in need of additional therapeutic options,” said Michael
Corbo, Chief Development Officer, Inflammation & Immunology, Global Product Development. “We believe that XELJANZ has the
potential to provide patients with psoriatic arthritis and their physicians a new treatment option that also offers oral
administration. If approved, XELJANZ or once-daily XELJANZ XR would be the first and only Janus kinase inhibitor for the treatment
of this chronic inflammatory disease.”
Two pivotal Phase 3 studies were included in the submission package. OPAL Broaden was conducted in conventional synthetic
disease-modifying antirheumatic drug (csDMARD) inadequate response (IR) and tumor necrosis factor inhibitor (TNFi)-naïve patient
populations. The study included an active control arm of adalimumab. However, the study was not designed for non-inferiority or
superiority comparisons between adalimumab and XELJANZ. OPAL Beyond was conducted in TNFi-IR patients and was the first PsA study
focused exclusively in this population. Both studies met their primary efficacy endpoints showing a statistically significant
improvement with XELJANZ 5 mg and 10 mg BID compared to treatment with placebo at three months as measured by American College of
Rheumatology 20 (ACR20) response and change from baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) score. In
both studies adverse events were more frequent with XELJANZ 5 mg and 10 mg BID versus placebo. Overall safety findings were
consistent with those observed in the broader rheumatology clinical development program for XELJANZ. Interim results from OPAL
Balance, the long-term extension study of XELJANZ in patients with active PsA, were also included in the submission package.
About Psoriatic Arthritis
Psoriatic Arthritis (PsA) is a chronic inflammatory multisystem disease. PsA can cause joint pain and stiffness, skin and nail
psoriasis, swollen toes and fingers, persistent painful tendonitis, and irreversible joint damage. There are an estimated three
million people in the U.S. and Europe combined with active PsA. Real world disease prevalence may be even higher because it is
often misdiagnosed or goes undiagnosed altogether.
About XELJANZ (tofacitinib citrate) and XELJANZ XR (tofacitinib citrate) extended-release
XELJANZ®/XELJANZ XR® (tofacitinib citrate) is a prescription medicine called a Janus kinase (JAK)
inhibitor. XELJANZ is not currently approved for the treatment of PsA.
As the developer of XELJANZ/XELJANZ XR, Pfizer is a leader in JAK innovation. The XELJANZ RA development program includes more
than eight years of safety data from the long-term extension studies representing over 21,100 patient-years of drug exposure to
date.
XELJANZ is approved in more than 80 countries around the world for the treatment of moderately to severely active rheumatoid
arthritis (RA). In the United States, Argentina, and Macau, XELJANZ XR is the first once-daily oral JAK inhibitor approved for the
treatment of moderately to severely active RA.
Pfizer is committed to advancing the science of JAK inhibition and enhancing understanding of XELJANZ 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. 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.
- 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. 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 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/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.
