NEW YORK–(BUSINESS WIRE)–Pfizer Inc. (NYSE:PFE) announced today top-line results from ORAL Strategy, a Phase 3B/4 study of XELJANZ® (tofacitinib citrate) 5mg twice daily (BID) in the treatment of moderate to severe rheumatoid arthritis (RA). ORAL Strategy is the first trial to compare a JAK inhibitor as monotherapy or in combination with methotrexate (MTX) versus adalimumab (Humira) plus MTX in MTX inadequate responders using ACR50 at Month 6 as the primary endpoint. There were three comparisons, which found:
- XELJANZ 5mg plus MTX met its primary endpoint in demonstrating non-inferiority versus Humira plus MTX
- XELJANZ 5mg monotherapy did not meet its primary endpoint of non-inferiority versus Humira plus MTX or versus XELJANZ plus MTX
“ORAL Strategy is representative of the type of innovative and clinically meaningful trials that Pfizer Inflammation & Immunology believes are important to help advance patient care and the science of JAK inhibition,” said Michael Corbo, Chief Development Officer, Inflammation & Immunology, Global Product Development. “We are pleased that we demonstrated non-inferiority of XELJANZ plus MTX versus Humira plus MTX, reinforcing the efficacy of XELJANZ combination therapy. We will continue to analyze the monotherapy data from this study and look forward to sharing the full results of ORAL Strategy at an upcoming scientific forum.”
ORAL Strategy is a 12-month, double-blind, head-to-head study which included 1,152 patients randomized into one of three study arms that were independently compared against each other:
- XELJANZ 5 mg BID as monotherapy (n=386)
- XELJANZ 5 mg BID in combination with a weekly dose of MTX (15-25 mg) (n=378)
- Humira 40 mg every-other-week via subcutaneous injection in combination with a weekly dose of MTX (15-25 mg) (n=388)
The safety findings were consistent with the known adverse events and serious adverse events profile for XELJANZ.
The RA clinical development program has over 20 clinical trials and to-date represents more than 21,100 patient-years of drug exposure. The long-term extension program, spanning over eight years of safety experience, is one of the largest in the RA category with respect to number of patients and patient-years of exposure.

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