Pfizer Highlights Leadership in Rheumatology and Inflammation with Data to be Presented at the ACR/ARHP 2014 Annual Meeting
21 Abstracts, Including Additional Clinical Trial Data and Real-World Analyses, Add to the Body of Evidence for XELJANZ® (Tofacitinib Citrate) as a Treatment Option for Adults with Moderate to Severe Rheumatoid Arthritis - - - Efficacy Results from a Phase 2 Study of Anti-IL-6 in Patients with Systemic Lupus Erythematosus - - - Phase 1 Abstracts for Two Pfizer Biosimilars in Development; Both Assets Move into Phase 3 Comparability Trials
Pfizer Inc. announced today that it will present data for several of its marketed and investigational medicines for inflammatory and immunological conditions at the American College of Rheumatology (ACR) / Association of Rheumatology Health Professionals (ARHP) 2014 Annual Meeting (November 14-19, Boston, Massachusetts). Twenty-one abstracts for XELJANZ® (tofacitinib citrate) will be presented, including the six-year safety and efficacy analyses from long-term extension (LTE) studies and a summary of real-world patient experience, additional post-hoc analyses from the clinical development program, and health and economics outcomes research, adding to the substantial body of evidence for XELJANZ as an oral treatment option for moderate to severe rheumatoid arthritis (RA). Data will also be presented for several additional Pfizer assets, including PF-04236921, an investigational anti-IL-6 biologic in Phase 2 development for Systemic Lupus Erythematosus (SLE), LYRICA® (pregabalin) capsules CV in fibromyalgia, and two biosimilars [PF-05280586, a potential biosimilar to Rituxan®/MabThera1 (rituximab) and PF-06438179, a potential biosimilar to Remicade®2 (infliximab)].
“Inflammation is one of the core research areas for Pfizer; our robust inflammation program has spanned over 60 years and includes more than 10 assets under investigation at various stages of development,” said Steve Romano, MD, senior vice president and Head, Global Medicines Development for the Pfizer Global Innovative Pharmaceutical business. “Through our research, Pfizer is focused on addressing unmet needs for people living with inflammatory diseases that are often chronic and debilitating, such as rheumatoid arthritis and lupus. Pfizer is pleased to share new data from this growing portfolio during the ACR annual meeting as it demonstrates our continued commitment to researching and sharing scientific evidence for inflammatory conditions.”
XELJANZ Data to be Presented
Highlights from the XELJANZ abstracts include post-hoc analyses from the ORAL Start study comparing the relationship between clinical measures of efficacy and patient-reported outcomes (PROs) in RA patients treated with XELJANZ monotherapy compared to methotrexate (MTX)(presentation 2488), a podium presentation of efficacy and safety observations up to six years from two open-label long-term extension studies evaluating 4,858 patients treated for a total exposure of 12,359 patient-years (presentation 849), and an analysis of post-marketing spontaneous adverse event reports over 18 months since the launch of XELJANZ in 2012 (presentation 465). Five abstracts using health economics and outcomes research on the current RA treatment paradigm from real-world data sources, including XELJANZ, will also be presented.
In the United States, XELJANZ is indicated for the treatment of adults with moderate to severe RA who have had an inadequate response or intolerance to MTX. XELJANZ may be used alone 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 approved dose is a 5 mg pill taken twice daily. XELJANZ is not indicated in MTX-naïve patients.
Additional Data from the Pfizer Inflammation Portfolio
Pfizer will also present abstracts on an anti-IL-6 compound in subjects with SLE and on LYRICA (pregabalin) capsules CV in fibromyalgia.
Phase 1 data will be presented at the conference for two Pfizer biosimilars in development: PF-05280586, a potential biosimilar to Rituxan®/MabThera1 (rituximab) and PF-06438179, a potential biosimilar to Remicade®2 (infliximab).
“Based on the completion of these studies, we have initiated Phase 3 comparability trials for these assets,” said Dr. Salomon Azoulay, global clinical and medical affairs head, Pfizer Global Established Pharma. “We now have three biosimilars, including PF-05280014, a potential biosimilar to Herceptin®3(trastuzumab), in Phase 3 trials.”

XELJANZ 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.
- 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).

LYRICA is indicated for the management of neuropathic pain associated with diabetic peripheral neuropathy, management of post herpetic neuralgia, as adjunctive therapy for adult patients with partial onset seizures, management of fibromyalgia and management of neuropathic pain associated with spinal cord injury.
Important Safety Information
LYRICA is contraindicated in patients with known hypersensitivity to pregabalin or any of its other components. Angioedema and hypersensitivity reactions have occurred in patients receiving pregabalin therapy.
There have been postmarketing reports of hypersensitivity in patients shortly after initiation of treatment with LYRICA. Adverse reactions included skin redness, blisters, hives, rash, dyspnea, and wheezing. Discontinue LYRICA immediately in patients with these symptoms.
There have been postmarketing reports of angioedema in patients during initial and chronic treatment with LYRICA. Specific symptoms included swelling of the face, mouth (tongue, lips, and gums), and neck (throat and larynx). There were reports of life-threatening angioedema with respiratory compromise requiring emergency treatment. Discontinue LYRICA immediately in patients with these symptoms.
Antiepileptic drugs (AEDs) including LYRICA increase the risk of suicidal thoughts or behavior in patients taking AEDs for any indication. Monitor patients treated with any AED for any indication for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Pooled analyses showed clinical trial patients taking an AED had approximately twice the risk of suicidal thoughts or behavior than placebo treated patients. The estimated incidence rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43 percent, compared to 0.24 percent among 16,029 placebo-treated patients, representing an increase of approximately one patient for every 530 patients treated with an AED.
The most common adverse reactions across all LYRICA clinical trials are dizziness, somnolence, dry mouth, edema, blurred vision, weight gain, constipation, euphoric mood, balance disorder, increased appetite, and thinking abnormal (primarily difficulty with concentration/attention).
Inform patients taking LYRICA that dizziness and somnolence may impair their ability to perform potentially hazardous tasks such as driving or operating complex machinery until they have sufficient experience with LYRICA to determine its effect on cognitive and motor function.
In controlled studies, a higher proportion of patients treated with LYRICA reported blurred vision (7 percent) than did patients treated with placebo (2 percent), which resolved in a majority of cases with continued dosing. Consider more frequent assessment for patients who are already routinely monitored for ocular conditions.
Higher frequency of weight gain and edema was observed in patients taking both LYRICA and thiazolidinedione antidiabetic drugs. Exercise caution when coadministering these drugs. Patients who are taking other drugs associated with angioedema such as angiotensin converting enzyme inhibitors (ACE- inhibitors) may be at increased risk of developing angioedema. Exercise caution when using LYRICA in patients who have had a previous episode of angioedema.
LYRICA may exacerbate the effects of oxycodone, lorazepam, or ethanol on cognitive and gross motor functioning.
Patients with a history of drug or alcohol abuse may have a higher chance of misuse or abuse of LYRICA.
Withdraw LYRICA gradually over a minimum of 1 week. Discontinue LYRICA immediately in patients with symptoms of hypersensitivity or angioedema.
Patients with a creatinine clearance of 30 to 60 mL/min had a greater incidence of discontinuation due to adverse reactions than patients with normal creatinine clearance. Adjust the daily dose of LYRICA for patients with reduced renal function (creatinine clearance ≤60 mL/min) and in those undergoing hemodialysis. Administer a supplemental dose of LYRICA immediately following every 4-hour hemodialysis treatment.
In standard, preclinical in vivo lifetime carcinogenicity studies of LYRICA, an unexpectedly high incidence of hemangiosarcoma was identified in 2 different strains of mice. The clinical significance of this finding is unknown. In clinical studies across various patient populations comprising 6396 patient-years of exposure in patients >12 years of age, new or worsening preexisting tumors were reported in 57 patients.
