INCHEON, Korea and Jersey City, N.J., United States – August 17, 2022 – Samsung Bioepis Co., Ltd. and Organon & Co. (NYSE: OGN) today announced the U.S. Food and Drug Administration (FDA) has approved the citrate-free, high-concentration (100 mg/mL) formulation of HADLIMA™ (adalimumab-bwwd), a biosimilar referencing HUMIRA® (adalimumab). HADLIMA will be available in pre-filled syringe and autoinjector options, and the autoinjector was specifically designed with the patient in mind. HADLIMA was previously approved by the FDA as a low-concentration (50 mg/mL) formulation in July 2019 and outside the US that formulation has been available in various markets globally under different brand names, with over 5 million doses sold since 2018.1,2
“With this approval, we now have both a low and high concentration adalimumab biosimilar approved by the FDA, marking an important step towards expanding treatment options for patients suffering from certain chronic, autoimmune diseases,” said Byoungin Jung, Vice President and Regulatory Affairs Team Leader, Samsung Bioepis. “By leveraging our development expertise, manufacturing excellence and supply chain reliability, we will continue our work to ensure healthcare systems have more affordable treatment options available,” she added.
“Based on our success commercializing our adalimumab biosimilar in other markets around the world, combined with our established presence in the biosimilar space, we are excited about the opportunity to launch HADLIMA in the US in 2023,” said Joe Azzinaro, Vice President, Global Commercial Lead Biosimilars, Organon. “Today, adalimumab is the largest drug expense in the US. We look forward to making our biosimilar available for those that rely on it to help manage their disease.”
The approval of citrate-free, high-concentration HADLIMA was based on clinical data from a randomized, single-blind, two-arm, parallel group, single-dose study that compared the pharmacokinetics, safety, tolerability, and immunogenicity of two formulations of HADLIMA (100 mg/mL vs 50 mg/mL) in healthy volunteers.3
HADLIMA is expected to be launched on or after July 1, 2023 by Organon.
A biosimilar is a biologic product that is highly similar to and has no clinically meaningful differences from an existing FDA-approved reference product.4 Biologics are the fastest-growing class of therapeutic products in the U.S., and biosimilars can increase competition in the marketplace, potentially lowering health care costs.4 Wider use of biosimilars could result in savings of $100 billion in the U.S. between 2020 to 2024 by stimulating market competition.5
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 adults and pediatric patients 5 years of age and older.
Limitations of Use: The effectiveness of HADLIMA 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
Patients treated with 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: 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 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 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 (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.
Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers including HADLIMA. 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 HADLIMA. 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 HADLIMA-treated patients compared to control patients.
• Non-melanoma skin cancer (NMSC) was reported during clinical trials for HADLIMA-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 HADLIMA.
• In HADLIMA 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.
• Anaphylaxis and angioneurotic edema have been reported following HADLIMA administration. If a serious allergic reaction occurs, stop HADLIMA and institute appropriate therapy.
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. 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.
• TNF blockers, including HADLIMA, 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.
• There is a known association between intermediate uveitis and central demyelinating disorders.
• Rare reports of pancytopenia, including aplastic anemia, have been reported with TNF blockers. Medically significant cytopenia has been infrequently reported with HADLIMA.
• Consider stopping HADLIMA 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 HADLIMA; exercise caution and monitor carefully.
• Treatment with HADLIMA 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.
• Patients 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 HADLIMA in utero is unknown. Risks and benefits should be considered prior to vaccinating (live or live-attenuated) exposed infants.
The most common adverse reactions in HADLIMA clinical trials (>10%) were: infections (e.g., upper respiratory, sinusitis), injection site reactions, headache, and rash.
