SAFETY CONSIDERATIONS1

Serious Infections

Patients treated with HUMIRA are at increased risk for developing serious infections that may lead to hospitalization or death. These infections include active tuberculosis (TB), reactivation of latent TB, invasive fungal infections, and bacterial, viral, and other infections due to opportunistic pathogens. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.

Malignancies

Lymphoma, including a rare type of T-cell lymphoma, and other malignancies, some fatal, have been reported in patients treated with TNF blockers, including HUMIRA.

Other Serious Adverse Reactions

Patients treated with HUMIRA also may be at risk for other serious adverse reactions, including anaphylaxis, hepatitis B virus reactivation, demyelinating disease, cytopenias, pancytopenia, heart failure, and a lupus-like syndrome.


INDICATION1


Psoriatic Arthritis: HUMIRA is indicated, alone or in combination with non-biologic DMARDs, for reducing signs and symptoms, inhibiting the progression of structural damage, and improving physical function in adult patients with active psoriatic arthritis.


Efficacy in psoriatic arthritis

ADEPT: A randomized, controlled trial of patients with moderate to severe active psoriatic arthritis (PsA)1-3

ADEPT evaluated the efficacy and safety of HUMIRA in patients with active PsA over 48 weeks

  • 24-week, double-blind study followed by an open-label extension (OLE) phase with HUMIRA

ADEPT study design2,3

ADEPT was a 24-week, randomized, double-blind, placebo-controlled study of 313 adults with moderately to severely active PsA (≥3 swollen joints and ≥3 tender or painful joints) and had either active psoriatic skin lesions or a documented history of psoriasis. Patients were required to have a history of inadequate response or an intolerance to NSAID therapy for PsA. Patients with psoriatic involvement of ≥3% of BSA were evaluated for PASI response. Treatment consisted of HUMIRA 40 mg or placebo EOW given subcutaneously. Patients on MTX at enrollment (158/313) and taking a stable dose of ≤30 mg/week for >1 month could remain on the same dose. After week 12, patients who failed to have at least a 20% decrease in both swollen and tender joint counts on 2 consecutive visits could receive rescue therapy with corticosteroids or DMARDs. All patients who completed the 24-week study were eligible for long-term treatment with HUMIRA in an OLE study. Co-primary endpoints were ACR 20 response at week 12 and change in mTSS for HUMIRA at week 48 vs placebo at week 24.

OLE: 285 patients entered the 120-week extension trial measuring the effects of treatment with HUMIRA on the efficacy endpoints of the randomized, controlled study. 115 patients received HUMIRA 40 mg EOW. All patients had a radiographic measure at baseline, week 24, week 48, and at week 96 or week 144. In the analysis of the mean change in mTSS through week 144, data were imputed. For patients who didn’t have a week 144 mTSS, week 96 mTSS was used.

HUMIRA significantly improved signs and symptoms of PsA1,2

ACR responses at week 12 and 24

HUMIRA significantly inhibited joint damage progression compared to placebo1-3

  • At week 48 of the OLE
    — HUMIRA-treated patients had a mean change from baseline of -0.2 ± 4.9 SD in mTSS compared to mean change of +0.9 ± 3.1 SD at week 24 in placebo-treated patients (P<0.001; co-primary endpoint)1
    — mTSS scores at baseline were 23.4 for HUMIRA and 22.1 for placebo.
  • At week 24, 91% (n=144) of HUMIRA-treated patients showed no radiographic progression compared with 71% (n=152) of placebo-treated patients3†

The mTSS, which included distal interphalangeal (DIP) joints (ie, not identical to the TSS used for rheumatoid arthritis), was used by readers blinded to treatment group to assess the radiographs.1 For HUMIRA patients who did not have an mTSS at week 48, the mTSS was imputed by linear extrapolation using the baseline and week 24 scores.4

Defined as a change in mTSS of ≤ 0.5 from baseline.


ADEPT OLE: radiographic assessment through 144 weeks5

  • Patients treated with HUMIRA 40 mg EOW (n=115) from baseline had a mean change of 0.5 ± 4.20 in mTSS at week 144
    — All patients had a radiographic measure at baseline, week 24, week 48, and at week 96 or week 144. In this analysis, data are imputed.

OLE populations generally consist of treatment responders. Patients who are unable to tolerate the drug or who do not respond to the drug drop out.

IMPORTANT SAFETY INFORMATION for HUMIRA (adalimumab)1

SERIOUS INFECTIONS

Patients treated with HUMIRA 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.

Discontinue HUMIRA if a patient develops a serious infection or sepsis.

Reported infections include:

  • Active tuberculosis (TB), including reactivation of latent TB. Patients with TB have frequently presented with disseminated or extrapulmonary disease. Test patients for latent TB before HUMIRA use and during therapy. Initiate treatment for latent TB prior to HUMIRA 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. Consider empiric anti-fungal therapy 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.

Carefully consider the risks and benefits of treatment with HUMIRA prior to initiating therapy in patients with chronic or recurrent infection. Monitor patients closely for the development of signs and symptoms of infection during and after treatment with HUMIRA, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy.

  • Do not start HUMIRA in patients with an active infection, including localized infections.
  • Patients older than 65 years, patients with co-morbid conditions, and/or patients taking concomitant immunosuppressants may be at greater risk of infection.
  • Consider the risks and benefits of treatment in patients with chronic or recurrent infection or with underlying conditions which may predispose them to infection, patients who have been exposed to TB, patients with a history of opportunistic infection, or patients who have resided or traveled in regions where TB or mycoses are endemic.
  • Patients who develop a new infection should undergo a prompt and complete diagnostic workup, and appropriate antimicrobial therapy should be initiated.
  • Drug interactions with biologic products: A higher rate of serious infections has been observed in rheumatoid arthritis patients treated with rituximab who received subsequent treatment with a TNF blocker. Concurrent use of HUMIRA with biologic DMARDs (e.g., anakinra or abatacept) or other TNF blockers is not recommended based on the possible increased risk for infections and other potential pharmacological interactions.

MALIGNANCY

Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, including HUMIRA. Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers, including HUMIRA. These cases have had a very aggressive disease course and have been fatal. The majority of reported TNF blocker cases have occurred in patients with Crohn’s disease or ulcerative colitis and the majority were in adolescent and young adult males. Almost all of these patients had received treatment with azathioprine or 6-mercaptopurine concomitantly with a TNF blocker at or prior to diagnosis. It is uncertain whether the occurrence of HSTCL is related to use of a TNF blocker or a TNF blocker in combination with these other immunosuppressants.

  • Consider the risks and benefits of HUMIRA treatment prior to initiating or continuing therapy in a patient with known malignancy.
  • More cases of malignancies were observed among HUMIRA-treated patients compared to control patients in clinical trials.
  • Non-melanoma skin cancer (NMSC) has been reported during clinical trials for HUMIRA-treated patients. Examine all patients, particularly those with a history of prolonged immunosuppressant or PUVA therapy, for the presence of NMSC prior to and during treatment with HUMIRA.
  • In HUMIRA clinical trials, there was an approximate 3-fold higher rate of lymphoma than expected in the general U.S. population. Patients with chronic inflammatory diseases, particularly those with highly active disease and/or chronic exposure to immunosuppressant therapies, may be at higher risk of lymphoma than the general population, even in the absence of TNF blockers.
  • Postmarketing cases of acute and chronic leukemia were reported with TNF blocker use. Approximately half of the postmarketing cases of malignancies in children, adolescents, and young adults receiving TNF blockers were lymphomas; other cases included rare malignancies associated with immunosuppression and malignancies not usually observed in children and adolescents.

HYPERSENSITIVITY

  • Anaphylaxis and angioneurotic edema have been reported following HUMIRA administration.
  • If a serious allergic reaction occurs, stop HUMIRA and institute appropriate therapy.

HEPATITIS B VIRUS REACTIVATION

  • Use of TNF blockers, including HUMIRA, may increase the risk of reactivation of hepatitis B virus (HBV) in patients who are chronic carriers. Some cases have been fatal.
  • Evaluate patients at risk for HBV infection for prior evidence of HBV infection before initiating TNF blocker therapy.
  • Exercise caution in patients who are carriers of HBV and monitor them during and after treatment with HUMIRA.
  • Discontinue HUMIRA and begin antiviral therapy in patients who develop HBV reactivation.
  • Exercise caution when considering resumption of HUMIRA therapy after appropriate treatment for HBV.

NEUROLOGIC REACTIONS

  • TNF blockers, including HUMIRA, have been associated in rare cases with new onset or exacerbation of central nervous system and peripheral demyelinating diseases, including multiple sclerosis, optic neuritis, and Guillain-Barré syndrome.
  • Exercise caution when considering HUMIRA for patients with these disorders.

HEMATOLOGIC REACTIONS

  • Rare reports of pancytopenia, including aplastic anemia, have been reported with TNF blockers. Medically significant cytopenia (e.g., thrombocytopenia, leukopenia) has been infrequently reported with HUMIRA.
  • Consider stopping HUMIRA in patients with significant hematologic abnormalities.

CONGESTIVE HEART FAILURE

  • Worsening or new onset congestive heart failure (CHF) may occur.
  • Exercise caution in patients with CHF and monitor them carefully.

AUTOIMMUNITY

  • Treatment with HUMIRA may result in the formation of autoantibodies and, rarely, in development of a lupus-like syndrome.
  • Discontinue treatment if symptoms of a lupus-like syndrome develop.

IMMUNIZATIONS

  • Patients on HUMIRA should not receive live vaccines.
  • It is recommended that pediatric patients, if possible, be brought up to date with all immunizations in agreement with current immunization guidelines prior to initiating HUMIRA therapy.

ADVERSE REACTIONS

  • The most common adverse reactions in HUMIRA clinical trials (incidence >10%) were: infections (e.g., upper respiratory, sinusitis), injection site reactions, headache, and rash.

INDICATIONS1

  • Rheumatoid Arthritis: HUMIRA is indicated, alone or in combination with methotrexate or other non-biologic DMARDs, for reducing signs and symptoms, inducing major clinical response, inhibiting the progression of structural damage, and improving physical function in adult patients with moderately to severely active rheumatoid arthritis.
  • Juvenile Idiopathic Arthritis: HUMIRA is indicated, alone or in combination with methotrexate, for reducing signs and symptoms of moderately to severely active polyarticular juvenile idiopathic arthritis in patients 2 years of age and older.
