Remicade(R) Receives EU Approval as First and Only Biologic Treatment for Pediatric Crohn's DiseaseRevised Labeling Allows Pediatric Patients with Severe, Active Crohn's Disease to Benefit from REMICADE Therapy
HORSHAM, Pa. and KENILWORTH, N.J., June 7 (HSMN NewsFeed) -- Centocor, Inc. and Schering-Plough Corporation (NYSE: SGP ) today announced that the European Commission has approved a new indication for REMICADE® (infliximab) allowing for the treatment of severe, active Crohn's disease (CD) in pediatric patients aged 6 to 17 years, who have not responded to conventional therapy including a corticosteroid, an immunomodulator and primary nutrition therapy, or who are intolerant to, or have contraindications for, such therapies. REMICADE has been studied only in combination with conventional immunosuppressive therapy. This approval follows a positive opinion granted in March by the Committee for Medicinal Products for Human Use (CHMP) for the European Medicines Agency (EMEA).
"Crohn's disease significantly impacts the quality of life of children suffering from this condition," said Salvatore Cucchiara, M.D., Department of Pediatrics, Gastrointestinal Motility and Endoscopy Unit, University of Naples. "Infliximab provides physicians with a new treatment option that addresses the unique aspects of this difficult-to-treat disease in the pediatric population."
REMICADE is the first and only biologic therapy approved in the EU for the treatment of pediatric CD, a debilitating condition that causes inflammation of the gastrointestinal tract, typically resulting in symptoms such as diarrhea, fever, abdominal pain, weight loss and in some patients, delayed development and stunted growth.
"This approval recognizes the unique value of REMICADE as it is the first and only biologic therapy available to children suffering with Crohn's disease in Europe, who previously had limited therapy options," said Robert J. Spiegel, M.D., chief medical officer, Schering-Plough Research Institute.
In May 2006, the United States Food and Drug Administration (FDA) approved REMICADE for pediatric patients with moderately to severely active CD who have had an inadequate response to conventional therapy. REMICADE was first approved in the U.S. for adult Crohn's disease in 1998 and later for adult ulcerative colitis in 2005.
The safety and efficacy of REMICADE across all indications have been well established in clinical trials over the past 14 years and through commercial experience with nearly 925,000 patients treated worldwide across all indications.
The label extension will permit physicians to administer a 5 mg/kg intravenous infusion of REMICADE over a 2-hour period followed by additional 5 mg/kg infusion doses at two and six weeks after the first infusion, then every eight weeks thereafter. Some patients may require a shorter dosing interval to maintain clinical benefit, while for others a longer dosing interval may be sufficient. Available data do not support further REMICADE treatment in pediatric patients not responding within the first 10 weeks of treatment.
Clinical Trial Information: REACH
The approval was based on data from the Phase III REACH (a Randomized, Multicenter, Open-label Study to Evaluate the Safety and Efficacy of Anti-TNF Monoclonal Antibody REMICADE in Pediatric Subjects with Moderate to Severe Crohn's Disease) trial. In the REACH trial, 112 patients (6 to 17 years of age; all required to be receiving 6-MP, AZA or MTX; 35% receiving corticosteroids) with moderate to severe, active Crohn's disease (median PCDAI of 40) and an inadequate response to conventional therapies received 5 mg/kg infliximab at weeks 0, 2, and 6. Patients assessed by the investigator to be in clinical response at week 10 were randomized and received 5 mg/kg infliximab at either q8 weeks or q12 weeks as a maintenance treatment regimen. Patients who lost clinical response during maintenance treatment could receive infliximab at a higher frequency or dose.
The proportion of subjects in clinical response at week 10 was 88.4% (99/112). The proportion of subjects achieving clinical remission at week 10 was 58.9% (66/112). At week 30, the proportion of subjects in clinical remission was higher in the q8 week (59.6%, 31/52) than the q12 week maintenance treatment group (35.3%, 18/51; p=0.013). At week 54, the proportion of subjects in clinical remission was 55.8% (29/52) and 23.5% (12/51) in the q8 week and q12 week maintenance groups, respectively (p<0.001).
Thirty-two evaluable pediatric patients (9 in the q8 week and 23 in the q12 week maintenance group) lost response and then received infliximab at a higher dose or more frequently. Twenty-four of these thirty-two patients (75.0%) regained clinical response.
Of the 22 subjects that had fistulas at baseline, 63.6% (14/22), 59.1% (13/22) and 68.2% (15/22) were in complete fistula response at weeks 10, 30 and 54, respectively, in the combined q8 week and q12 weeks maintenance group.
In addition, statistically and clinically significant improvements in quality of life and height, as well as a significant reduction in corticosteroid use, were observed.
The following adverse events were reported more commonly in pediatric Crohn's disease patients in the REACH trial than in adult Crohn's disease patients: anaemia (10.7%), blood in stool (9.7%), leukopenia (8.7%), flushing (8.7%), viral infection (7.8%), neutropenia (6.8%), bone fracture (6.8%), bacterial infection (5.8%), and respiratory tract allergic reaction (5.8%). Other special considerations are discussed below.
About Pediatric Crohn's Disease
Crohn's disease is a chronic illness that causes inflammation of the gastrointestinal tract, typically resulting in symptoms such as diarrhea, fever, abdominal pain and weight loss.
Children with Crohn's disease may also experience delayed development and stunted growth. Although it can involve any area of the gastrointestinal tract from the mouth to the anus, it most commonly affects the small intestine and/or colon.
REMICADE is a monoclonal antibody that specifically targets TNF-alpha, which has been shown to play a role in Crohn's disease (CD), rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), ulcerative colitis (UC) and psoriasis (PsO).
REMICADE was approved in the EU in 1999 for the treatment of severe, active CD in patients who have not responded despite a full and adequate course of therapy with a corticosteroid and/or an immunosuppressant; or who are intolerant to or have medical contraindications for such therapies. REMICADE also is indicated for the treatment of fistulizing, active CD in patients who have not responded despite a full and adequate course of therapy with conventional treatment (including antibiotics, drainage and immunosuppressive therapy).
For RA patients in the EU, REMICADE, in combination with methotrexate, is indicated for the reduction of signs and symptoms as well as the improvement in physical function in patients with active disease when the response to disease-modifying drugs, including methotrexate, has been inadequate, and in patients with severe, active and progressive disease not previously treated with methotrexate or other DMARDs. In these patient populations, a reduction in the rate of the progression of joint damage, as measured by X-ray, has been demonstrated.
In the EU, REMICADE is also indicated for the treatment of AS in patients who have severe axial symptoms, elevated serological markers of inflammatory activity and who have responded inadequately to conventional therapy. REMICADE is also approved for the treatment of active and progressive PsA in patients when the response to previous disease-modifying anti-rheumatic drugs therapy has been inadequate. REMICADE should be administered in combination with MTX or alone in patients who show intolerance to MTX or for whom MTX is contraindicated. REMICADE is also approved in the EU for the treatment of moderate to severe plaque psoriasis in patients who failed to respond to, or have a contraindication to, or are intolerant of other systemic therapy including cyclosporine, MTX or PUVA (psoralen plus ultraviolet A light).
In February 2006, REMICADE was approved in the EU for the treatment of moderately-to- severely active UC in patients who have had an inadequate response to conventional therapy, including corticosteroids and 6-MP or AZA, or who are intolerant to or have medical contraindications for such therapies. This approval made REMICADE the first and only biologic therapy approved to treat moderate-to-severe UC in the EU.
REMICADE is the only anti-TNF biologic therapy available as an IV form. Unlike self-administered therapies that require patients to inject themselves frequently, REMICADE is the only anti-TNF biologic administered directly by caregivers in the clinic or office setting. In RA (3 mg/kg), CD (5 mg/kg), PsA (5 mg/kg), psoriasis (5 mg/kg) and UC (5 mg/kg), REMICADE is a two-hour infusion administered every 8 weeks, following a standard induction regimen that requires treatment at weeks 0, 2 and 6. As a result, REMICADE patients may require as few as six treatments each year. In AS (5 mg/kg), REMICADE is a two-hour infusion administered every 6 to 8 weeks, following a standard induction regimen that requires treatment at weeks 0, 2 and 6. In carefully selected patients with RA who have tolerated three initial two-hour infusions of REMICADE, consideration may be given to administering subsequent infusions over a period of not less than one hour. Shortened infusions at doses greater than 6 mg/kg have not been studied.
Furthermore, if an RA patient has an inadequate response or loses response after initial treatment with REMICADE, consideration may be given to increase the dose step-wise by approximately 1.5 mg/kg, up to a maximum of 7.5 mg/kg every 8 weeks. Alternatively, administration of 3 mg/kg as often as every 4 weeks may be considered. If adequate response is achieved, patients should be continued on the selected dose or dose frequency. Continued therapy should be carefully reconsidered in patients who show no evidence of therapeutic benefit within the first 12 weeks of treatment or after the dose has been adjusted.
REMICADE treatment is to be initiated and supervised by qualified physicians experienced in the diagnosis and treatment of rheumatoid arthritis, inflammatory bowel diseases, ankylosing spondylitis, psoriatic arthritis or psoriasis. REMICADE infusions should be administered by qualified healthcare professionals trained to detect any infusion related issues. Patients treated with REMICADE should be given a package leaflet and a special alert card.
Centocor discovered REMICADE and has exclusive marketing rights to the product in the United States. Schering-Plough markets REMICADE in all countries outside of the United States, except in Japan and parts of the Far East where Tanabe Seiyaku, Ltd. markets the product and in China where Xian- Janssen markets REMICADE.
Important Safety Information
There are reports of serious infections, including tuberculosis (TB), sepsis and pneumonia. Some of these infections have been fatal. Tell your doctor if you have had recent or past exposure to people with TB. Your doctor will evaluate you for TB and perform a TB test. If you have latent (inactive) TB, your doctor should begin TB treatment before you start REMICADE. REMICADE can lower your ability to fight infections, so if you are prone to or have a history of infections, or develop any signs of an infection such as fever, fatigue, cough, flu or warm, red or painful skin while taking REMICADE, tell your doctor right away. Also, tell your doctor if you are scheduled to receive a vaccine or if, you have lived in a region where histoplasmosis or coccidioidomycosis is common.
Reports of a type of blood cancer called lymphoma in patients on REMICADE or other TNF blockers are rare but occur more often than expected for people in general. People who have been treated for rheumatoid arthritis, Crohn's disease, ankylosing spondylitis, or psoriatic arthritis for a long time, particularly those with highly active disease may be more prone to develop lymphoma. Cancers, other than lymphoma, have also been reported. Rarely, children and young adults who have been treated for Crohn's disease with REMICADE in combination with azathioprine or 6-mercaptopurine have developed a rare type of lymphoma, hepatosplenic T cell lymphoma (HSTL), that often results in death. If you take REMICADE or other TNF blockers, your risk for developing lymphoma or other cancers may increase. You should also tell your doctor if you have had or develop lymphoma or other cancers or if you have a lung disease called chronic obstructive pulmonary disease (COPD).
Many people with heart failure should not take REMICADE; so prior to treatment you should discuss any heart condition with your doctor. Tell your doctor right away if you develop new or worsening symptoms of heart failure (such as shortness of breath, swelling of your ankles or feet, or sudden weight gain).
Reactivation of hepatitis B virus has been reported in patients who are carriers of this virus and are taking TNF blockers, such as REMICADE. Some of these cases have been fatal. Tell your doctor if you know or think you may be a carrier of hepatitis B virus or if you experience signs of hepatitis B infection, such as feeling unwell, poor appetite, tiredness, fever, skin rash and/or joint pain.
There have been rare cases of serious liver injury in people taking REMICADE, some fatal. Tell your doctor if you have liver problems and contact your doctor immediately if you develop symptoms such as jaundice (yellow skin and eyes), dark brown urine, right-sided abdominal pain, fever, or severe fatigue.
Blood disorders have been reported, some fatal. Tell your doctor if you develop possible signs of blood disorders such as persistent fever, bruising, bleeding, or paleness while taking REMICADE. Nervous system disorders have also been reported. Tell your doctor if you have or have had a disease that affects the nervous system, or if you experience any numbness, weakness, tingling, visual disturbances or seizures while taking REMICADE.
Allergic reactions, some severe have been reported during or after infusions with REMICADE. Signs of an allergic reaction include hives, difficulty breathing, chest pain, high or low blood pressure, swelling of face and hands, and fever or chills. Tell your doctor if you have experienced a severe allergic reaction. The most common side effects of REMICADE are: respiratory infections, such as sinus infections and sore throat, headache, rash, coughing, and stomach pain.
