ENBREL EFFICACY FOR MODERATE TO SEVERE POLYARTICULAR JUVENILE IDIOPATHIC ARTHRITIS

Our passion for patient care never rests

ENBREL can reduce signs and symptoms in your patients with moderately to severely active polyarticular juvenile idiopathic arthritis (JIA).1 Together, we’ve been helping JIA patients feel better for the past 15 years.

The JIA Trial

The JIA trial was a 2-part, multicenter trial of 69 patients ages 4 to 17 years with moderately to severely active polyarticular-course JIA who were refractory to or intolerant of MTX. Patients remained on stable dose of a single NSAID and/or prednisone.2,3

JIA 30 at 3 months of the single-arm, open-label period

Disease flare at 4 months of the double-blind period*

Together, we can help relieve symptoms for patients

Clinical response

  • A majority of patients on ENBREL demonstrated a clinical response (JIA 30) at 3 months1

Disease flare

  • Less than 25% of patients taking ENBREL experienced a disease flare at 4 months of the double-blind period1*
  • From the start of part 2, the median time to flare was ≥116 days for patients who received ENBREL and 28 days for patients who received placebo1
  • Each component of the JIA core set criteria worsened in the arm that received placebo and remained stable or improved in the arm that continued on ENBREL1

Together, we can help patients get sustained results2‡

Patients continuously on ENBREL had sustained results out to 4 years2‡

  • 94% of patients achieved JIA 30 (n=30/32)2
  • 91% of patients achieved JIA 50 (n=29/32)2
  • 78% of patients achieved JIA 70 (n=25/32)2

Most of the responding patients who continued ENBREL therapy without interruption in an open-label follow-up maintained responses for up to 48 months.1

Disease flare defined as a ≥30% worsening in three of the six JIA core set criteria and ≥30% improvement in not more than one of the six JIA core set criteria and a minimum of two active joints.

Studies have not been done to assess the effects of continued ENBREL therapy in polyarticular JIA patients who do not respond within 3 months of initiating ENBREL therapy, or to assess the combination of ENBREL with MTX.

Physical function improvement through 4 years

Together, we can help improve functional measures for patients

  • Patients treated with ENBREL experienced substantial improvements in functional measures (CHAQ)2,4
  • CHAQ assesses physical function in 8 domains: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and activities4
  • During the double-blind period of the JIA Trial, the ENBREL arm showed 54% median improvement in CHAQ, whereas the placebo arm showed 0% median improvement in CHAQ from baseline at 7 months4

IMPORTANT SAFETY INFORMATION AND INDICATIONS
SERIOUS INFECTIONS

Patients treated with ENBREL are at 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 or were predisposed to infection because of their underlying disease. ENBREL should not be initiated in the presence of sepsis, active infections, or allergy to ENBREL or its components. ENBREL should be discontinued if a patient develops a serious infection or sepsis. Reported infections include: 1) Active tuberculosis (TB), including reactivation of latent TB. Patients with TB have frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent TB before ENBREL use and periodically during therapy. Treatment for latent infection should be initiated prior to ENBREL use, 2) 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 antifungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness, and 3) Bacterial, viral, and other infections due to opportunistic pathogens, including Legionella and Listeria.

The risks and benefits of treatment with ENBREL should be carefully considered prior to initiating therapy in patients 1) with chronic or recurrent infection, 2) who have been exposed to TB, 3) who have resided or traveled in areas of endemic TB or endemic mycoses, or 4) with underlying conditions that may predispose them to infections such as advanced or poorly controlled diabetes. Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with ENBREL, including the possible development of TB in patients who tested negative for latent TB prior to initiating therapy.

MALIGNANCIES

Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with tumor necrosis factor (TNF) blockers, including ENBREL.

In adult clinical trials of all TNF blockers, more cases of lymphoma were seen compared to control patients. The risk of lymphoma may be up to several-fold higher in RA patients. The role of TNF blocker therapy in the development of malignancies is unknown.

Cases of acute and chronic leukemia have been reported in association with postmarketing TNF blocker use in RA and other indications. The risk of leukemia may be higher in patients with RA (approximately 2-fold) than the general population.

Melanoma and non-melanoma skin cancer (NMSC) have been reported in patients treated with TNF blockers, including ENBREL. Periodic skin examinations should be considered for all patients at increased risk for skin cancer.

Pediatric Patients

In patients who initiated therapy at ≤18 years of age, approximately half of the reported malignancies were lymphomas (Hodgkin’s and non-Hodgkin’s lymphoma). Other cases included rare malignancies usually associated with immunosuppression and malignancies that are not usually observed in children and adolescents. Most of the patients were receiving concomitant immunosuppressants.

NEUROLOGIC REACTIONS

Treatment with TNF-blocking agents, including ENBREL, has been associated with rare (<0.1%) cases of new onset or exacerbation of central nervous system demyelinating disorders, some presenting with mental status changes and some associated with permanent disability, and with peripheral nervous system demyelinating disorders. Cases of transverse myelitis, optic neuritis, multiple sclerosis, Guillain-Barré syndromes, other peripheral demyelinating neuropathies, and new onset or exacerbation of seizure disorders have been reported in postmarketing experience with ENBREL therapy. Prescribers should exercise caution in considering the use of ENBREL in patients with preexisting or recent-onset central or peripheral nervous system demyelinating disorders.

CONGESTIVE HEART FAILURE

Cases of worsening congestive heart failure (CHF) and, rarely, new-onset cases have been reported in patients taking ENBREL. Caution should be used when using ENBREL in patients with CHF. These patients should be carefully monitored.

HEMATOLOGIC REACTIONS

Rare cases of pancytopenia, including aplastic anemia, some fatal, have been reported. The causal relationship to ENBREL therapy remains unclear. Exercise caution when considering ENBREL in patients who have a previous history of significant hematologic abnormalities. Advise patients to seek immediate medical attention if they develop signs or symptoms of blood dyscrasias or infection. Consider discontinuing ENBREL if significant hematologic abnormalities are confirmed.

HEPATITIS B REACTIVATION

Reactivation of hepatitis B has been reported in patients who were previously infected with hepatitis B virus (HBV) and received concomitant TNF-blocking agents, including ENBREL. Most reports occurred in patients also taking immunosuppressive agents, which may contribute to hepatitis B reactivation. Exercise caution when considering ENBREL in these patients.

ALLERGIC REACTIONS

Allergic reactions associated with administration of ENBREL during clinical trials have been reported in <2% of patients. If an anaphylactic reaction or other serious allergic reaction occurs, administration of ENBREL should be discontinued immediately and appropriate therapy initiated.

IMMUNIZATIONS

Live vaccines should not be administered to patients on ENBREL. Pediatric patients, if possible, should be brought up to date with all immunizations prior to initiating ENBREL. In patients with exposure to varicella virus, temporarily discontinue ENBREL and consider prophylactic treatment with Varicella Zoster Immune Globulin.

AUTOIMMUNITY

Autoantibodies may develop with ENBREL, and rarely lupus-like syndrome or autoimmune hepatitis may occur. These may resolve upon withdrawal of ENBREL. Stop ENBREL if lupus-like syndrome or autoimmune hepatitis develops.

WEGENER’S GRANULOMATOSIS PATIENTS

The use of ENBREL in patients with Wegener’s granulomatosis receiving immunosuppressive agents (eg, cyclophosphamide) is not recommended.

MODERATE TO SEVERE ALCOHOLIC HEPATITIS

Based on a study of patients treated for alcoholic hepatitis, exercise caution when using ENBREL in patients with moderate to severe alcoholic hepatitis.

ADVERSE REACTIONS

The most commonly reported adverse reactions in RA clinical trials were injection site reaction and infection. In clinical trials of all other adult indications, adverse reactions were similar to those reported in RA clinical trials.

In general, the adverse reactions in pediatric patients were similar in frequency and type as those seen in adult patients. The types of infections reported in pediatric patients were generally mild and consistent with those commonly seen in the general pediatric population.

DRUG INTERACTIONS

The use of ENBREL in patients receiving concurrent cyclophosphamide therapy is not recommended. The risk of serious infection may increase with concomitant use of abatacept therapy. Concurrent therapy with ENBREL and anakinra is not recommended. Hypoglycemia has been reported following initiation of ENBREL therapy in patients receiving medication for diabetes, necessitating a reduction in anti-diabetic medication in some of these patients.

Please see Prescribing Information and Medication Guide.

INDICATIONS

ENBREL is indicated for reducing signs and symptoms, inducing major clinical response, inhibiting the progression of structural damage, and improving physical function in patients with moderately to severely active rheumatoid arthritis. ENBREL can be initiated in combination with methotrexate (MTX) or used alone.

ENBREL is indicated for reducing signs and symptoms of moderately to severely active polyarticular juvenile idiopathic arthritis in patients ages 2 and older.

ENBREL is indicated for reducing signs and symptoms, inhibiting the progression of structural damage of active arthritis, and improving physical function in patients with psoriatic arthritis (PsA). ENBREL can be used with or without MTX.

ENBREL is indicated for reducing signs and symptoms in patients with active ankylosing spondylitis.

ENBREL is indicated for the treatment of patients 4 years or older with chronic moderate to severe plaque psoriasis (PsO) who are candidates for systemic therapy or phototherapy.

AUTOIMMUNITY

Autoantibodies may develop with ENBREL, and rarely lupus-like syndrome or autoimmune hepatitis may occur. These may resolve upon withdrawal of ENBREL. Stop ENBREL if lupus-like syndrome or autoimmune hepatitis develops.

WEGENER’S GRANULOMATOSIS PATIENTS

The use of ENBREL in patients with Wegener’s granulomatosis receiving immunosuppressive agents (eg, cyclophosphamide) is not recommended.

MODERATE TO SEVERE ALCOHOLIC HEPATITIS

Based on a study of patients treated for alcoholic hepatitis, exercise caution when using ENBREL in patients with moderate to severe alcoholic hepatitis.

ADVERSE REACTIONS

The most commonly reported adverse reactions in RA clinical trials were injection site reaction and infection. In clinical trials of all other adult indications, adverse reactions were similar to those reported in RA clinical trials.

In general, the adverse reactions in pediatric patients were similar in frequency and type as those seen in adult patients. The types of infections reported in pediatric patients were generally mild and consistent with those commonly seen in the general pediatric population.

DRUG INTERACTIONS

The use of ENBREL in patients receiving concurrent cyclophosphamide therapy is not recommended. The risk of serious infection may increase with concomitant use of abatacept therapy. Concurrent therapy with ENBREL and anakinra is not recommended. Hypoglycemia has been reported following initiation of ENBREL therapy in patients receiving medication for diabetes, necessitating a reduction in anti-diabetic medication in some of these patients.

Please see Prescribing Information and Medication Guide.
