Multiple-Switching StudyABRILADA is FDA designated as interchangeable with Humira® (adalimumab) based on evidence established in the first and only multiple-switching study in patients with moderately to severely active RA1,2*†

Adalimumab is prescribed more frequently for RA than any of its other FDA-approved indications3‡

  • A phase 3, open-label, randomized, parallel-group multiple-switching study that adhered to the rigorous guidelines set forth by the FDA2
ReferencesADAs=antidrug antibodies; AUCτ=area under plasma concentration-time curve over dosing interval; CL/F=apparent clearance; Cav=average serum concentration; Cmax=maximum serum concentration; Ctrough=predose concentrations; EOW=every other week; FDA=Food and Drug Administration; NAbs=neutralizing antibodies; PK=pharmacokinetic; RA=rheumatoid arthritis; Tmax=time of maximum observed serum concentration.*ABRILADA is interchangeable for the indications of use, dosage forms, strengths, and routes of administration described in Prescribing Information.1,4ABRILADA is approved for all indications of Humira except pediatric ulcerative colitis, adolescent hidradenitis suppurativa, and pediatric uveitis.This information is an estimate derived from the use of information under license from the following IQVIA information service: US I&I Comprehensive Indication Parsing 2024 for the period January 2018 through February 2024. IQVIA expressly reserves all rights, including rights of copying, distribution, and republication.§Patients were switched between high concentration Humira (40 mg/0.4 mL [100 mg/mL]) and standard concentration ABRILADA (40 mg/0.8 mL [50 mg/mL]).2ABRILADA demonstrated a similar PK profile to Humira in moderately to severely active RA patients2

This supported the FDA designation of interchangeability between ABRILADA and Humira1,2

  • Geometric mean ratios (GMRs) for Cmax and AUCτ (90% confidence intervals) were within the prespecified equivalence margin of 80%-125%2
  • The PK endpoints of Cmax and AUCτ were used as a presumptive surrogate for efficacy2II
ReferencesCI=confidence interval.IIThese measures can be used to establish if the risk of diminished efficacy from switching between Humira and ABRILADA was greater than the risk of using continuous Humira.2Cmax and AUCτ at weeks 30 to 32 demonstrated equivalence between groups. The GMRs and corresponding 90% CIs for Cmax (102.56 [89.78–117.17]) and AUCτ (105.31 [89.16–124.39]) were within the prespecified equivalence margin of 80%–125%.2

This supported the FDA designation of interchangeability between ABRILADA and Humira1,2

  • Mean steady-state PK parameters were similar between the switching and non-switching groups2
#Data taken from treatment period 4 in the PK population.2Similar immunogenicity was observed in both switching and non-switching groups of patients with moderately to severely active RA2
  •  The number and proportion of ADA/NAb-positive patients was similar between the 2 groups at weeks 10 and 32
There was a similar safety profile in both groups in the multiple-switching study2

Rates of adverse events (AEs), including AEs of special interest2#

  • In the lead-in period of the study, 24% of patients experienced treatment-emergent adverse events (TEAEs) and 3% of patients experienced treatment-emergent serious adverse events (TESAEs)
    • The most commonly reported TEAEs in the lead-in period were infections and infestations (9%), skin and subcutaneous tissue disorders (5%), abnormal laboratory investigations (4%), and general disorders and administrative-site conditions (4%)
  • After randomization to switching and non-switching groups, 38% of patients in the switching group experienced TEAEs vs 29% in the non-switching group
    • Of these patients, 1% in the switching group experienced TESAEs vs 4% in the non-switching group
    • The most commonly reported TEAEs after randomization to switching and non-switching groups were infections and infestations (10% of patients in the switching group vs 12% of patients in the non-switching group)
#Prespecified AEs of special interest included: hypersensitivity events, blood and lymphatic system events, cardiovascular events, demyelinating conditions, gastric and hepatic events, infections, malignancies, and lupus-like syndrome.2

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 (6MP) 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.
