• sBLA based on Phase 4 study which assessed pharmacokinetic similarity between two treatment groups: multi-switching group alternating between Humira and high-concentration HADLIMA vs. Humira-continued group
• Filing acceptance reinforces Samsung Bioepis and Organon’s commitment to provide better access to biologic medicines for patients in the United States

INCHEON, South Korea and JERSEY CITY, N.J., Nov. 07, 2023 (GLOBE NEWSWIRE) -- Samsung Bioepis Co., Ltd. and Organon & Co. (NYSE: OGN) today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the Supplemental Biologics License Application (sBLA) for the interchangeability designation for HADLIMA™ (adalimumab-bwwd) injection 40 mg/0.4 mL, a biosimilar to Humira® (adalimumab). The sBLA was submitted to the FDA by Samsung Bioepis in August 2023.

The sBLA submission was based on clinical data from the Phase 4, randomized, double-blind, 1:1 ratio, parallel-group, multiple-dose, active comparator, multicenter clinical study (NCT05510063) to assess the pharmacokinetic similarity between two treatment groups: patients with moderate to severe plaque psoriasis who switched multiple times between high-concentration formulations of Humira and HADLIMA versus patients receiving Humira continuously.1

“Following our announcement on the interchangeability study’s topline results in August, we are excited to share the progress on this sBLA filing on interchangeability. This filing acceptance is a reinforcement of our commitment to provide better access to biologic medicines for patients in the United States,” said Byoung In Jung, Vice President and Regulatory Affairs Team Leader at Samsung Bioepis. “We will continue to drive our goal of realizing the value of biosimilars for patients and contributing to the sustainability of healthcare systems.”

“An interchangeability designation may play a role beyond enabling pharmacy substitution. We believe that interchangeability could help increase physician confidence with prescribing biosimilars, especially in the high-concentration formulation which is used by the majority of Humira patients. We remain committed to helping more patients access biosimilar alternatives,” said Jon Martin, Head, US Biosimilars at Organon.

HADLIMA (adalimumab-bwwd) was first approved by the FDA in July 2019 as a low-concentration (40 mg/0.8 mL) formulation of prefilled syringe and prefilled autoinjector. The high-concentration (40 mg/0.4 mL) formulation of prefilled syringe and prefilled autoinjector of HADLIMA was approved in August 2022. HADLIMA was introduced into the US commercial market on July 1, 2023 and is marketed by Organon.

About InterchangeabilityBoth biosimilars and interchangeable biosimilars have no clinically meaningful differences in safety, purity, and potency as the original biologic for approved indications.2 To be designated as “interchangeable,” information must be submitted to show that:

• the biological product is biosimilar to the reference product,
• the biological product can be expected to produce the same clinical result as the reference product in any given patient, and
• for a biological product that is administered more than once to an individual, the risk in terms of safety or diminished efficacy of alternating or switching between use of the biological product and the reference product is not greater than the risk of using the reference product without such alternation or switch.3

Once a biosimilar product is designated as an interchangeable biosimilar by the FDA, it can be used to replace the reference product by someone other than the prescriber (such as a pharmacist), without the need to consult the prescriber, depending on the state pharmacy laws.2 This is similar to how generic drugs are commonly substituted for brand name drugs.

About HADLIMA™ (adalimumab-bwwd) Injection 40 mg/0.4 mL and 40 mg/0.8 mL

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 antirheumatic 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 tumor necrosis factor (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.

• Hidradenitis Suppurativa: HADLIMA is indicated for the treatment of moderate to severe hidradenitis suppurativa in adult patients.

• Uveitis: HADLIMA is indicated for the treatment of non-infectious intermediate, posterior, and panuveitis in adult patients.

SELECTED SAFETY INFORMATION

SERIOUS INFECTIONSPatients 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

• who have been exposed to TB

• with a history of opportunistic infection

• who resided in or traveled in regions where mycoses are endemic

• 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 HADLIMA, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy.

• Do not start HADLIMA 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 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 HADLIMA with other biologic DMARDs (eg, anakinra or abatacept) or other TNF blockers is not recommended based on the possible increased risk for infections and other potential pharmacological interactions.

MALIGNANCYLymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, including adalimumab products. 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 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 HADLIMA 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 and ultraviolet A (PUVA) therapy, for the presence of NMSC prior to and during treatment with HADLIMA.

• 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.

HYPERSENSITIVITYAnaphylaxis and angioneurotic edema have been reported following adalimumab administration. If a serious allergic reaction occurs, stop HADLIMA and institute appropriate therapy.

HEPATITIS B VIRUS REACTIVATIONUse of TNF blockers, including HADLIMA, 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 HADLIMA treatment.

Discontinue HADLIMA and begin antiviral therapy in patients who develop HBV reactivation. Exercise caution when resuming HADLIMA after HBV treatment.

NEUROLOGIC REACTIONSTNF 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 HADLIMA for patients with these disorders; discontinuation of HADLIMA should be considered if any of these disorders develop.

HEMATOLOGIC REACTIONSRare reports of pancytopenia, including aplastic anemia, have been reported with TNF blockers. Medically significant cytopenia has been infrequently reported with adalimumab products.

Consider stopping HADLIMA if significant hematologic abnormalities occur.

CONGESTIVE HEART FAILUREWorsening 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.

AUTOIMMUNITYTreatment 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.

IMMUNIZATIONSPatients on HADLIMA should not receive live vaccines.

Pediatric patients, if possible, should be brought up to date with all immunizations before initiating HADLIMA 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 adalimumab products in utero is unknown. Risks and benefits should be considered prior to vaccinating (live or live-attenuated) exposed infants.

ADVERSE REACTIONSThe most common adverse reactions in adalimumab clinical trials (>10%) were: infections (eg, upper respiratory, sinusitis), injection site reactions, headache, and rash.

Before prescribing HADLIMA, please read the Prescribing Information, including the Boxed Warning about serious infections and malignancies. The Medication Guideand Instructions for Usealso are available.
