BRUSSELS, Nov. 13, 2012 /PRNewswire/ -- UCB announced extensive results from the Phase 3 study - RAPID-axSpA - at the American College of Rheumatology's (ACR) 2012 Annual Scientific Meeting in Washington D.C., U.S.
RAPID-axSpA enrolled patients with active axial spondyloarthritis (axSpA), including patients with ankylosing spondylitis (AS) and axSpA without radiographic evidence of AS (non-radiographic axSpA [nr-axSpA]). The study showed that compared to placebo, both dosing regimens of certolizumab pegol reduced the signs and symptoms of axSpA in the overall study population with improvements observed in both the AS and nr-axSpA sub-populations. Results also indicated that certolizumab pegol improved productivity in the workplace and in the household, increased participation in daily activities, reduced inflammation in the sacroiliac joint and spine, and improved patient-reported outcomes such as back pain, fatigue and physical functioning.1,2,3,4
Certolizumab pegol is not approved for the treatment of axSpA. UCB intends to file global regulatory submissions for certolizumab pegol in axSpA by the end of 2012.
"AxSpA is a debilitating condition that primarily presents in a young, active population and comprises of a spectrum of clinical symptoms, with the main one being chronic inflammatory back pain," said Professor Deodhar, Medical Director, Rheumatology Clinics Division of Arthritis & Rheumatic Diseases, Oregon Health & Science University, U.S. "People living with AS have X-ray evidence of structural damage in the sacroiliitic joints and are the most well-defined sub-population, while patients with axSpA without radiographic evidence of AS are less well acknowledged today."
"The RAPID-axSpA study is the first randomized, controlled, Phase 3 trial of an anti-TNF to include the broad axSpA population including patients with both AS and nr-axSpA," said Professor Robert Landewe, University of Amsterdam and Atrium Medical Center Heerlen, the Netherlands. "The study showed that the disease burden was similar at baseline for the AS and nr-axSpA sub-populations. Certolizumab pegol reduced the clinical burden of axSpA, with similar reductions compared to placebo observed across both certolizumab pegol dosing regimens in both AS and nr-axSpA sub-populations."

The primary efficacy variable of the RAPID-axSpA study was the ASAS20 response rate at week 12. The study met its primary endpoint and clinical improvements in the ASAS20 responses were statistically significant in both dosing arms vs. placebo (57.7%, 63.6% vs. 38.3% for 200 mg every 2 weeks and 400 mg every 4 weeks certolizumab pegol vs. placebo, n=111, 107 and 107, p<0.05). Improvements were observed as early as week one (40.5%, 34.6% vs. 14.2% for 200 mg every two weeks and 400 mg every four weeks certolizumab pegol vs. placebo).
The improvement in ASAS20 response at week 12 was observed at week 24. Sub-population analyses also indicated improvements at weeks 12 and 24 in both AS and nr-axSpA sub-populations. At weeks 12 and 24 both dosing regimens of certolizumab pegol indicated improvements vs. placebo in measurements of disease activity, spinal mobility and physical function in the entire axSpA population with improvements also observed vs. placebo in both the AS and nr-axSpA sub-populations.
Adverse events occurred in 70.4% vs. 62.6% of certolizumab pegol (combined dose) treated patients vs. placebo, serious AEs in 4.7% vs. 4.7% and serious infections in 1.1% vs. 0.1 The most common adverse events (occurred in >5% of patients taking certolizumab pegol or placebo) were nasopharyngitis, upper respiratory tract infection, increased creatine phosphokinase and headache.5

Abstract title: Improvements in productivity at paid work and within household, and increased participation in daily activities after 24 weeks of certolizumab pegol treatment of axial spondyloarthritis patients, including patients with ankylosing spondylitis: results of a phase 3 double-blind randomized placebo-controlled study2
Both dosing regimens of certolizumab pegol compared to placebo showed improved household productivity in patients with axSpA. Household work days missed per month due to axSpA for patients taking both dosing regimens of certolizumab pegol decreased from baseline to week 24. For patients taking certolizumab pegol 200 mg every 2 weeks the number of days decreased from 5.8 at baseline to 3.0 at week 4 and 2.3 at week 24 (n=111) vs. 6.9, 5.4 and 5.6 for placebo (n=107). Compared to placebo patients taking both doses of certolizumab pegol also reported a decrease in the number of days per month where household work productivity was reduced by half or more from baseline through to week 24.
Both dosing regimens of certolizumab pegol compared to placebo also showed improved workplace productivity in patients with axSpA. Employed patients taking both dosing regimens of certolizumab pegol reported reduced absenteeism from work with a decrease in days missed per month due to axSpA from week 4 through to week 24. For patients taking certolizumab pegol 200 mg every 2 weeks, the number of days missing from work per month decreased from 2.3 at baseline to 1.4 at week 4 and 1.1 at week 24 (n=77, 78 and 80) vs. 2.4, 1.9 and 2.0 for placebo (n=67, 68 and 66). Employed patients taking both doses of certolizumab pegol also reported a decrease in work presenteeism, i.e. a reduction in the number of days per month where work productivity was reduced by half or more due to axSpA.

In the U.S., certolizumab pegol is indicated for the treatment of adult patients with moderately-to-severely active rheumatoid arthritis (RA), and for reducing the signs and symptoms of Crohn's disease (CD) and maintaining clinical response in adult patients with moderately-to-severely active disease who have had an inadequate response to conventional therapy.6 Certolizumab pegol is marketed under the trade name Cimzia®.
In the European Union, Cimzia® in combination with methotrexate (MTX) is indicated for the treatment of moderate to severe active rheumatoid arthritis in adult patients inadequately responsive to disease-modifying anti-rheumatic drugs (DMARDs) including MTX. Cimzia® can be given as monotherapy in case of intolerance to MTX or when continued treatment with MTX is inappropriate.7
Note to editors 1,8,9,10
The ongoing 158 week RAPID-axSpA study is double-blind and placebo-controlled up to week 24, dose-blind up to week 48 and then open-label to week 158. Patients (n=325) with active axSpA were randomized 1:1:1 to receive certolizumab pegol 200 mg every two weeks, 400 mg every four weeks or placebo (n=111, 107 and 107). This dosing schedule followed a loading dose of certolizumab pegol (400 mg) at weeks 0, 2 and 4. Patients enrolled in the study must have failed at least one non-steroidal anti-inflammatory drug (NSAID). Up to 40% of patients could have received one previous anti-TNF, provided they were not primary non-responders, as determined by the investigator. Within the placebo arm, patients who failed to achieve an ASAS20 response at weeks 14 and 16 were re-randomized at week 16 to receive certolizumab pegol 200 mg every 2 weeks or 400 mg every 4 weeks, following the loading dose.
About SpA and axSpA
SpA is the overall name of a family of inflammatory rheumatic diseases that can affect the spine and joints, ligaments and tendons. There are two main types of clinical presentation of SpA axSpA (symptoms predominantly related to the spine) and peripheral SpA (symptoms predominantly related to the peripheral joints).
AS is a chronic inflammatory rheumatic disease of the spine and is the most defined subset of axSpA. The symptoms of AS can vary, but most people experience back pain and stiffness due to inflammation which can proceed to fusion of the vertebrae. The condition can be severe, with around 1 in 10 people at risk of long-term disability. The condition usually occurs between 15 and 35 years of age, and rarely starts in old age, with prevalence estimated to be between 0.1% - 1.1% of the population. AS is more common in men than in women.
About axSpA without radiographic evidence of AS
Patients with no definitive sacroiliitis on conventional radiographs but similar clinical features and showing either sacroiliitis on MRI or who are HLA-B27 positive have axSpA without radiographic evidence of AS (non-radiographic axSpA [nr-axSpA]).
The Assessment of SpondyloArthritis international Society (ASAS20) improvement criteria is defined as an improvement of at least 20% and absolute improvement of at least one unit on a 0-10 scale in at least three of the four following domains: patient global assessment, pain assessment, patient function, and inflammation and the absence of deterioration in the remaining domain.
Cimzia® is the only PEGylated anti-TNF (Tumor Necrosis Factor). Cimzia® has a high affinity for human TNF-alpha, selectively neutralizing the pathophysiological effects of TNF-alpha. Over the past decade, TNF-alpha has emerged as a major target of basic research and clinical investigation. This cytokine plays a key role in mediating pathological inflammation, and excess TNF-alpha production has been directly implicated in a wide variety of diseases. The U.S. Food and Drug Administration (FDA) has approved Cimzia® for reducing signs and symptoms of Crohn's disease and maintaining clinical response in adult patients with moderately to severely active disease who have had an inadequate response to conventional therapy and for the treatment of adults with moderately to severely active rheumatoid arthritis. Cimzia® in combination with MTX is approved in the EU for the treatment of moderate to severe active RA in adult patients inadequately responsive to disease-modifying antirheumatic drugs (DMARDs) including MTX. Cimzia® can be given as monotherapy in case of intolerance to MTX or when continued treatment with MTX is inappropriate. UCB is also developing Cimzia® in other autoimmune disease indications. Cimzia® is a registered trademark of UCB PHARMA S.A.
Cimzia® (certolizumab pegol) in the U.S. important safety information
Risk of Serious Infections and Malignancy
Patients treated with CIMZIA are at an increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. CIMZIA should be discontinued if a patient develops a serious infection or sepsis. Reported infections include:
- Active tuberculosis, including reactivation of latent tuberculosis. Patients with tuberculosis have frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent tuberculosis before CIMZIA use and during therapy. Treatment for latent infection should be initiated prior to CIMZIA use.
- Invasive fungal infections, including histoplasmosis , coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness .
- Bacterial, viral and other infections due to opportunistic pathogens, including Legionella and Listeria.
The risks and benefits of treatment with CIMZIA should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection. Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with CIMZIA, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy.
Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, of which CIMZIA is a member. CIMZIA is not indicated for use in pediatric patients.
Patients treated with CIMZIA are at an increased risk for developing serious infections involving various organ systems and sites that may lead to hospitalization or death. Opportunistic infections due to bacterial, mycobacterial, invasive fungal, viral, parasitic, or other opportunistic pathogens including aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, histoplasmosis, legionellosis, listeriosis, pneumocystosis and tuberculosis have been reported with TNF blockers. Patients have frequently presented with disseminated rather than localized disease.
Treatment with CIMZIA should not be initiated in patients with an active infection, including clinically important localized infections. CIMZIA should be discontinued if a patient develops a serious infection or sepsis. Patients greater than 65 years of age, patients with co-morbid conditions, and/or patients taking concomitant immunosuppressants (e.g. corticosteroids or methotrexate) may be at a greater risk of infection. Patients who develop a new infection during treatment with CIMZIA should be closely monitored, undergo a prompt and complete diagnostic workup appropriate for immunocompromised patients, and appropriate antimicrobial therapy should be initiated. Appropriate empiric antifungal therapy should also be considered while a diagnostic workup is performed for patients who develop a serious systemic illness and reside or travel in regions where mycoses are endemic.
During controlled and open-labeled portions of CIMZIA studies of Crohn's disease and other diseases , malignancies (excluding non-melanoma skin cancer) were observed at a rate of 0.5 per 100 patient-years among 4,650 CIMZIA-treated patients versus a rate of 0.6 per 100 patient-years among 1,319 placebo-treated patients. In studies of CIMZIA for Crohn's disease and other investigational uses, there was one case of lymphoma among 2,657 CIMZIA-treated patients and one case of Hodgkin lymphoma among 1,319 placebo-treated patients. In CIMZIA RA clinical trials (placebo-controlled and open label) a total of three cases of lymphoma were observed among 2,367 patients. This is approximately 2-fold higher than expected in the general population. Patients with RA, particularly those with highly active disease, are at a higher risk for the development of lymphoma. The potential role of TNF blocker therapy in the development of malignancies is not known.
Malignancies, some fatal, have been reported among children, adolescents, and young adults who received treatment with TNF-blocking agents (initiation of therapy less than or equal to 18 years of age), of which CIMZIA is a member. Approximately half of the cases were lymphoma (including Hodgkin's and non-Hodgkin's lymphoma, while the other cases represented a variety of different malignancies and included rare malignancies associated with immunosuppression and malignancies not usually observed in children and adolescents. Most of the patients were receiving concomitant immunosuppressants.
Cases of acute and chronic leukemia have been reported with TNF-blocker use. Even in the absence of TNF-blocker therapy, patients with RA may be at a higher risk (approximately 2-fold) than the general population for developing leukemia.
Cases of worsening congestive heart failure (CHF) and new onset CHF have been reported with TNF blockers. CIMZIA has not been formally studied in patients with CHF. Exercise caution when using CIMZIA in patients who have heart failure and monitor them carefully.
Symptoms compatible with hypersensitivity reactions, including angioedema, dyspnea, hypotension, rash, serum sickness, and urticaria, have been reported rarely following CIMZIA administration. If such reactions occur, discontinue further administration of CIMZIA and institute appropriate therapy.
Hepatitis B Reactivation
Use of TNF blockers, including CIMZIA, may increase the risk of reactivation of hepatitis B virus (HBV) in patients who are chronic carriers of this virus. Some cases have been fatal. Evaluate patients at risk for HBV infection for prior evidence of HBV infection before initiating CIMZIA therapy. Exercise caution in prescribing CIMZIA for patients identified as carriers of HBV, with careful evaluation and monitoring prior to and during treatment. In patients who develop HBV reactivation, discontinue CIMZIA and initiate effective anti-viral therapy with appropriate supportive treatment.
Use of TNF blockers, including CIMZIA, has been associated with rare cases of new onset or exacerbation of clinical symptoms and/or radiographic evidence of central nervous system demyelinating disease, including multiple sclerosis, and with peripheral demyelinating disease, including Guillain-Barre syndrome. Rare cases of neurological disorders, including seizure disorder, optic neuritis, and peripheral neuropathy have been reported in patients treated with CIMZIA. Exercise caution in considering the use of CIMZIA in patients with these disorders.
Rare reports of pancytopenia, including aplastic anemia, have been reported with TNF blockers. Medically significant cytopenia (e.g., leukopenia, pancytopenia, thrombocytopenia) has been infrequently reported with CIMZIA. Advise all patients to seek immediate medical attention if they develop signs and symptoms suggestive of blood dyscrasias or infection (e.g., persistent fever, bruising, bleeding, pallor) while on CIMZIA. Consider discontinuation of CIMZIA therapy in patients with confirmed significant hematologic abnormalities.
An increased risk of serious infections has been seen in clinical trials of other TNF blocking agents used in combination with anakinra or abatacept. Formal drug interaction studies have not been performed with rituximab or natalizumab; however because of the nature of the adverse events seen with these combinations with TNF blocker therapy, similar toxicities may also result from the use of CIMZIA in these combinations. Therefore, the combination of CIMZIA with anakinra, abatacept, rituximab, or natalizumab is not recommended. Interference with certain coagulation assays has been detected in patients treated with CIMZIA. There is no evidence that CIMZIA therapy has an effect on in vivo coagulation. CIMZIA may cause erroneously elevated aPTT assay results in patients without coagulation abnormalities.
Treatment with CIMZIA may result in the formation of autoantibodies and, rarely, in the development of a lupus-like syndrome. Discontinue treatment if symptoms of lupus-like syndrome develop.
Do not administer live vaccines or live-attenuated vaccines concurrently with CIMZIA.
In controlled Crohn's clinical trials, the most common adverse events that occurred in greater than or equal to 5% of CIMZIA patients (n=620) and more frequently than with placebo (n=614) were upper respiratory infection (20% CIMZIA, 13% placebo), urinary tract infection (7% CIMZIA, 6% placebo), and arthralgia (6% CIMZIA, 4% placebo). The proportion of patients who discontinued treatment due to adverse reactions in the controlled clinical studies was 8% for CIMZIA and 7% for placebo.
In controlled RA clinical trials, the most common adverse events that occurred in greater than or equal to 3% of patients taking CIMZIA 200 mg every other week with concomitant methotrexate (n=640) and more frequently than with placebo with concomitant methotrexate (n=324) were upper respiratory tract infection (6% CIMZIA, 2% placebo), headache (5% CIMZIA, 4% placebo), hypertension (5% CIMZIA, 2% placebo), nasopharyngitis (5% CIMZIA, 1% placebo), back pain (4% CIMZIA, 1% placebo), pyrexia (3% CIMZIA, 2% placebo), pharyngitis (3% CIMZIA, 1% placebo), rash (3% CIMZIA, 1% placebo), acute bronchitis (3% CIMZIA,1% placebo), fatigue (3% CIMZIA, 2% placebo). Hypertensive adverse reactions were observed more frequently in patients receiving CIMZIA than in controls. These adverse reactions occurred more frequently among patients with a baseline history of hypertension and among patients receiving concomitant corticosteroids and non-steroidal anti-inflammatory drugs. Patients receiving CIMZIA 400mg as monotherapy every 4 weeks in RA controlled clinical trials had similar adverse reactions to those patients receiving CIMZIA 200mg every other week. The proportion of patients who discontinued treatment due to adverse reactions in the controlled clinical studies was 5% for CIMZIA and 2.5% for placebo.

Cimzia® (certolizumab pegol) in EU/ EEA important safety information
Cimzia® was studied in 2367 patients with RA in controlled and open label trials for up to 57 months. The commonly reported adverse reactions (1-10%) in clinical trials with Cimzia® and post-marketing were viral infections (includes herpes, papillomavirus, influenza), bacterial infections (including abscess), rash, headache (including migraine), asthenia, leukopaenia (including lymphopaenia, neutropaenia), eosinophilic disorder, pain (any sites), pyrexia, sensory abnormalities, hypertension, pruritis (any sites), hepatitis (including hepatic enzyme increase), injection site reactions and nausea. Serious adverse reactions include sepsis, opportunistic infections, tuberculosis, herpes zoster, lymphoma, leukaemia, solid organ tumours, angioneurotic edema, cardiomyopathies (includes heart failure), ischemic coronary artery disorders, pancytopaenia, hypercoagulation (including thrombophlebitis, pulmonary embolism), cerebrovascular accident, vasculitis, hepatitis/hepatopathy (includes cirrhosis), and renal impairment/nephropathy (includes nephritis). In RA controlled clinical trials, 5% of patients discontinued taking Cimzia® due to adverse events vs. 2.5% for placebo.
Cimzia® is contraindicated in patients with hypersensitivity to the active substance or any of the excipients, active tuberculosis or other severe infections such as sepsis or opportunistic infections or moderate to severe heart failure.
Serious infections including sepsis, tuberculosis and opportunistic infections have been reported in patients receiving Cimzia®. Some of these events have been fatal. Monitor patients closely for signs and symptoms of infections including tuberculosis before, during and after treatment with Cimzia®. Treatment with Cimzia must not be initiated in patients with a clinically important active infection. If an infection develops, monitor carefully and stop Cimzia® if infection becomes serious. Before initiation of therapy with Cimzia®, all patients must be evaluated for both active and inactive (latent) tuberculosis infection. If active tuberculosis is diagnosed prior to or during treatment, Cimzia® therapy must not be initiated and must be discontinued. If latent tuberculosis is diagnosed, appropriate anti-tuberculosis therapy must be started before initiating treatment with Cimzia®. Patients should be instructed to seek medical advice if signs/symptoms (e.g. persistent cough, wasting/weight loss, low grade fever, listlessness) suggestive of tuberculosis occur during or after therapy with Cimzia®.
Reactivation of hepatitis B has occurred in patients receiving a TNF-antagonist including Cimzia® who are chronic carriers of the virus (i.e. surface antigen positive). Some cases have had a fatal outcome. Patients should be tested for HBV infection before initiating treatment with Cimzia®. Carriers of HBV who require treatment with Cimzia® should be closely monitored and in the case of HBV reactivation Cimzia® should be stopped and effective anti-viral therapy with appropriate supportive treatment should be initiated.
TNF antagonists including Cimzia® may increase the risk of new onset or exacerbation of clinical symptoms and/or radiographic evidence of demyelinating disease; of formation of autoantibodies and uncommonly of the development of a lupus-like syndrome; of severe hypersensitivity reactions. If a patient develops any of these adverse reactions, Cimzia® should be discontinued and appropriate therapy instituted.
With the current knowledge, a possible risk for the development of lymphomas, leukaemia or other malignancies in patients treated with a TNF antagonist cannot be excluded. Rare cases of neurological disorders, including seizure disorder, neuritis and peripheral neuropathy, have been reported in patients treated with Cimzia®.
Adverse reactions of the hematologic system, including medically significant cytopenia, have been infrequently reported with Cimzia®. Advise all patients to seek immediate medical attention if they develop signs and symptoms suggestive of blood dyscrasias or infection (e.g., persistent fever, bruising, bleeding, pallor) while on Cimzia®. Consider discontinuation of Cimzia® therapy in patients with confirmed significant hematological abnormalities.
The use of Cimzia® in combination with anakinra or abatacept is not recommended due to a potential increased risk of serious infections. As no data are available, Cimzia® should not be administered concurrently with live vaccines. The 14-day half-life of Cimzia® should be taken into consideration if a surgical procedure is planned. A patient who requires surgery while on Cimzia® should be closely monitored for infections.
