LoadingStudy description: Phase 3, open-label, randomized, parallel-group multiple-switching study of ABRILADA and Humira in patients with moderately to severely active RA who had received methotrexate for 12 or more weeks, and had been on a stable dose for ≥4 weeks before first dose of study medication. All patients received Humira for the first 10 weeks of the study. At week 10, patients were randomized to either a switching group (3 switches between Humira and ABRILADA), or a non-switching group (continuous dosing with Humira). Primary endpoints were maximum observed serum concentration (Cmax) and area under plasma concentration–time curve (AUCτ) during weeks 30–32 in the PK population.5ABRILADA is interchangeable for the indications of use, dosage forms, strengths and routes of administration described in Prescribing Information.1,2ABRILADA is approved for all indications of Humira except pediatric ulcerative colitis, adolescent hidradenitis suppurativa, and pediatric uveitis.An interchangeable biosimilar may be substituted at the pharmacy for the reference product without the intervention of the prescribing healthcare provider, depending on state pharmacy laws. Not all biosimilars are interchangeable. An interchangeable designation is granted by the FDA to only those biosimilars that meet additional data requirements demonstrating that patients who alternate between the reference product and the biosimilar will have the same clinical result as patients who are being treated with the reference product alone.8,9

Important Safety Information and UseSERIOUS INFECTIONS
​​​​​
Patients treated with adalimumab products including ABRILADA 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 ABRILADA 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 ABRILADA use and during therapy. Initiate treatment for latent TB prior to ABRILADA 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 ABRILADA prior to initiating therapy in patients: 1. with chronic or recurrent infection, 2. who have been exposed to TB, 3. with a history of opportunistic infection, 4. who resided in or traveled in regions where mycoses are endemic, 5. with underlying conditions that may predispose them to infection. Monitor patients closely for the development of signs and symptoms of infection during and after treatment with ABRILADA, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy.
  • Do not start ABRILADA during 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.
  • If an infection develops, monitor carefully and initiate appropriate therapy.
  • Drug interactions with biologic products: A higher rate of serious infections has been observed in rheumatoid arthritis (RA) patients treated with rituximab who received subsequent treatment with a tumor necrosis factor (TNF) blocker. An increased risk of serious infections has been seen with the combination of TNF blockers with anakinra or abatacept, with no demonstrated added benefit in patients with RA. Concomitant administration of ABRILADA with other biologic disease-modifying antirheumatic drugs (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 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 these patients had received treatment with azathioprine or 6-mercaptopurine (6–MP) 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 ABRILADA treatment prior to initiating or continuing therapy in a patient with known malignancy.
  • In clinical trials, more cases of malignancies were observed among adalimumab-treated patients compared to control patients.
  • Non-melanoma skin cancer (NMSC) was reported during clinical trials for adalimumab-treated patients. Examine all patients, particularly those with a history of prolonged immunosuppressant or psoralen plus ultraviolet A (PUVA) therapy, for the presence of NMSC prior to and during treatment with ABRILADA.
  • In adalimumab 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 administration of adalimumab products. If a serious allergic reaction occurs, stop ABRILADA and institute appropriate therapy.
HEPATITIS B VIRUS REACTIVATION
  • Use of TNF blockers, including ABRILADA, 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 ABRILADA treatment.
  • Discontinue ABRILADA and begin antiviral therapy in patients who develop HBV reactivation. Exercise caution when resuming ABRILADA after HBV treatment.
NEUROLOGIC REACTIONS
  • TNF blockers, including adalimumab products, have been associated with rare cases of 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 ABRILADA for patients with these disorders; discontinuation of ABRILADA should be considered if any of these disorders develop.
  • There is a known association between intermediate uveitis and central demyelinating disorders.
HEMATOLOGIC REACTIONS
  • Rare reports of pancytopenia, including aplastic anemia, have been reported with TNF blockers. Medically significant cytopenia has been infrequently reported with adalimumab products.
  • Consider stopping ABRILADA if significant hematologic abnormalities occur.
CONGESTIVE HEART FAILURE
  • Worsening and new onset congestive heart failure (CHF) has been reported with TNF blockers. Cases of worsening CHF have been observed with adalimumab products; exercise caution and monitor carefully.
AUTOIMMUNITY
  • Treatment with adalimumab products 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 ABRILADA should not receive live vaccines.
  • Pediatric patients, if possible, should be brought up to date with all immunizations before initiating ABRILADA therapy.
  • Adalimumab is actively transferred across the placenta during the third trimester of pregnancy and may affect immune response in the in utero exposed infant. The safety of administering live or live-attenuated vaccines in infants exposed to ABRILADA 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 adalimumab clinical trials (>10%) were: infections (e.g., upper respiratory, sinusitis), injection site reactions, headache, and rash.
Indications
