About HADLIMA™ (adalimumab-bwwd)

HADLIMA is a tumor necrosis factor (TNF) blocker indicated for:

Rheumatoid Arthritis - HADLIMA is indicated, alone or in combination with methotrexate or other non-biologic disease-modifying anti-rheumatic drugs (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 - HADLIMA 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.

Psoriatic Arthritis - HADLIMA 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.

Ankylosing Spondylitis - HADLIMA is indicated for reducing signs and symptoms in adult patients with active ankylosing spondylitis.

Crohn’s Disease - HADLIMA is indicated for the treatment of moderately to severely active Crohn’s disease in adults and pediatric patients 6 years of age and older.

Ulcerative Colitis - HADLIMA is indicated for the treatment of moderately to severely active ulcerative colitis in adult patients.

Limitations of Use: The effectiveness of adalimumab products has not been established in patients who have lost response to or were intolerant to TNF blockers.

Plaque Psoriasis - HADLIMA is indicated for the treatment of adult patients with moderate to severe chronic plaque psoriasis who are candidates for systemic therapy or phototherapy, and when other systemic therapies are medically less appropriate. HADLIMA should only be administered to patients who will be closely monitored and have regular follow-up visits with a physician.

Selected Safety Information

SERIOUS INFECTIONS

Patients treated with adalimumab products, including HADLIMA, 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 HADLIMA 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 HADLIMA use and during therapy. Initiate treatment for latent TB prior to HADLIMA 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 HADLIMA 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 HADLIMA, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy.

Treatment with HADLIMA should not be initiated in patients with an active infection, including localized infections. Patients 65 years of age and older, patients with co-morbid conditions and/or patients taking concomitant immunosuppressants (such as corticosteroids or methotrexate), may be at greater risk of infection. Consider the risks and benefits of treatment prior to initiating therapy in patients:

• with chronic or recurrent infection;
• who have been exposed to tuberculosis;
• with a history of an opportunistic infection;
• who have resided or traveled in areas of endemic tuberculosis or endemic mycoses, such as histoplasmosis, coccidioidomycosis, or blastomycosis; or
• with underlying conditions that may predispose them to infection.

Discontinue HADLIMA if a patient develops a serious infection or sepsis. For a patient who develops a new infection during treatment with HADLIMA, closely monitor them, perform a prompt and complete diagnostic workup appropriate for an immunocompromised patient, and initiate appropriate antimicrobial therapy.

Drug interactions with biologic products: In clinical studies in patients with RA, an increased risk of serious infections has been observed with the combination of TNF blockers with anakinra or abatacept, with no added benefit; therefore, use of HADLIMA with abatacept or anakinra is not recommended in patients with RA. A higher rate of serious infections has also been observed in patients with RA treated with rituximab who received subsequent treatment with a TNF blocker. There is insufficient information regarding the concomitant use of HADLIMA and other biologic products for the treatment of RA, PsA, AS, CD, UC and Ps. Concomitant administration of HADLIMA with other biologic DMARDs (e.g., anakinra and abatacept) or other TNF blockers is not recommended based upon 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 adalimumab products. Post-marketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers including adalimumab products. 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 TNF-blocker treatment including HADLIMA prior to initiating therapy in patients with a known malignancy other than a successfully treated non-melanoma skin cancer (NMSC) or when considering continuing a TNF blocker in patients who develop a malignancy.
• In the controlled portions of clinical trials of some TNF-blockers, including adalimumab products, more cases of malignancies have been observed among TNF-blocker-treated adult patients compared to control-treated adult patients.
• Non-melanoma skin cancer (NMSC) was reported during clinical trials for adalimumab-treated patients. Examine all patients, and in particular patients with a medical history of prior prolonged immunosuppressant therapy or psoriasis patients with a history of PUVA treatment for the presence of NMSC prior to and during treatment with HADLIMA.
• In the controlled portions of clinical trials of all the TNF-blockers in adults, more cases of lymphoma have been observed among TNF-blocker-treated patients compared to control-treated patients. There was approximately a 3-fold higher than expected rate in the general U.S. population. Patients with RA and other chronic inflammatory diseases, particularly those with highly active disease and/or chronic exposure to immunosuppressant therapies, may be at a higher risk than the general population for the development of lymphoma, even in the absence of TNF blockers.
• Post-marketing cases of acute and chronic leukemia were reported with TNF blocker use in RA and other indications.
• Malignancies, some fatal, have been reported among children, adolescents, and young adults who received treatment with TNF-blockers (initiation of therapy ≤ 18 years of age), of which HADLIMA is a member. Approximately half the cases were lymphomas, including Hodgkin's and non-Hodgkin's lymphoma. The other cases represented a variety of different malignancies and included rare malignancies usually associated with immunosuppression and malignancies that are not usually observed in children and adolescents.

HYPERSENSITIVITY REACTIONS

• Anaphylaxis and angioneurotic edema have been reported following administration of adalimumab products. If an anaphylactic or other serious allergic reaction occurs, immediately discontinue administration of HADLIMA and institute appropriate therapy. In clinical trials of adalimumab, hypersensitivity reactions (e.g., rash, anaphylactoid reaction, fixed drug reaction, non-specified drug reaction, urticaria) have been observed.

HEPATITIS B VIRUS REACTIVATION

• Use of TNF blockers, including HADLIMA, may increase the risk of reactivation of hepatitis B virus (HBV) in patients who are chronic carriers. In some instances, HBV reactivation occurring in conjunction with TNF blocker therapy has been fatal.
• Evaluate patients at risk for HBV infection for prior evidence of HBV infection before initiating TNF blocker therapy.
• Exercise caution in prescribing TNF blockers for patients identified as carriers of HBV and monitor them during and after HADLIMA treatment. Adequate data are not available on the safety or efficacy of treating patients who are carriers of HBV with anti-viral therapy in conjunction with TNF blocker therapy to prevent HBV reactivation.
• In patients who develop HBV reactivation, stop HADLIMA and initiate effective anti-viral therapy with appropriate supportive treatment. The safety of resuming TNF blocker therapy after HBV reactivation is controlled is not known. Therefore, exercise caution when considering resumption of HADLIMA therapy in this situation and monitor patients closely.

NEUROLOGIC REACTIONS

• Use of TNF blocking agents, including adalimumab products, 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 optic neuritis, and peripheral demyelinating disease, including Guillain-Barré syndrome.
• Exercise caution in considering the use of HADLIMA in patients with preexisting or recent-onset central or peripheral nervous system demyelinating disorders; discontinuation of HADLIMA should be considered if any of these disorders develop.

HEMATOLOGICAL REACTIONS

• Rare reports of pancytopenia including aplastic anemia have been reported with TNF blocking agents. Medically significant cytopenia has been infrequently reported with HADLIMA.
• Adverse reactions of the hematologic system, including medically significant cytopenia (e.g., thrombocytopenia, leukopenia) have been infrequently reported with adalimumab products. The causal relationship of these reports to adalimumab products remains unclear. 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 HADLIMA.
• Consider discontinuation of HADLIMA therapy in patients with confirmed significant hematologic abnormalities.

INCREASED RISK OF INFECTION WHEN USED WITH ANAKINRA

• Concurrent use of anakinra (an interleukin-1 antagonist) and another TNF-blocker, was associated with a greater proportion of serious infections and neutropenia and no added benefit compared with the TNF blocker alone in patients with RA. Therefore, the combination of HADLIMA and anakinra is not recommended.

HEART FAILURE

• Cases of worsening congestive heart failure (CHF) and new onset CHF have been reported with TNF blockers. Cases of worsening CHF have also been observed with adalimumab products. Adalimumab products have not been formally studied in patients with CHF; however, in clinical trials of another TNF blocker, a higher rate of serious CHF-related adverse reactions was observed. Exercise caution and monitor carefully.

AUTOIMMUNITY

• Treatment with adalimumab products may result in the formation of autoantibodies and, rarely, in the development of a lupus-like syndrome. If a patient develops symptoms suggestive of a lupus-like syndrome following treatment with HADLIMA, discontinue treatment.

IMMUNIZATIONS

• Patients on HADLIMA may receive concurrent vaccinations, except for live vaccines. No data are available on the secondary transmission of infection by live vaccines in patients receiving adalimumab products.
• 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 HADLIMA therapy. Patients on HADLIMA may receive concurrent vaccinations, except for live vaccines.
• The safety of administering live or live-attenuated vaccines in infants exposed to adalimumab products in utero is unknown. Risks and benefits should be considered prior to vaccinating (live or live- attenuated) exposed infants.

ADVERSE REACTIONS

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

Before prescribing HADLIMA, please read the accompanying Prescribing Information, including the Boxed Warning about serious infections and malignancies. The Medication Guide is also available.
