Comparing Long‐Term Infliximab Persistence Following a Switch to a Biosimilar in Patients With Inflammatory Bowel Disease: No Cause for Concern

Article

Author: Thin, Lena ; Olsen, Nicholas ; Winston, James ; van Langenberg, Daniel R. ; An, Yoon‐Kyo ; Srinivasan, Ashish ; Menon, Shankar ; Haifer, Craig ; Skinner, Thomas ; Jeffrey, Angus W. ; Ghaly, Simon ; Suo, Paulina ; Fernandes, Richard G.

ABSTRACT:

Introduction:

Several studies have demonstrated that switching stable patients with inflammatory bowel disease (IBD) from originator to biosimilar infliximab is noninferior to continuing originator infliximab. However, “real‐world” data comparing long‐term outcomes between switch and nonswitch cohorts is lacking. This study aimed to address this gap by comparing long‐term outcomes in IBD patients across switch and nonswitch cohorts.

Methods:

The SAME study was a multicenter, prospective parallel cohort noninferiority study, that enrolled Australian IBD patients in steroid‐free clinical remission on maintenance originator infliximab, who either continued originator infliximab (n = 141) or switched to biosimilar (CT‐P13) infliximab (n = 204). Here, we present long‐term outcomes, with treatment persistence beyond 48 weeks as the primary outcome. Disease worsening, defined as any of infliximab discontinuation, dose escalation, antibody development, or adverse event, were secondary outcomes of interest.

Results:

Of 345 patients enrolled in the SAME study, 320 (92.7%) patients were followed up beyond 48 weeks (median: 54.2 months [IQR 46.1–59.3]). There were no differences in infliximab discontinuation between switch and nonswitch cohorts (35.3% vs. 37.6%, p = 0.47). Infliximab discontinuation due to disease worsening (21.7% vs. 23.6%), dose escalation (35.2% vs. 32.4%), antibody development (5.3% vs. 11.3%), and infliximab‐related adverse events (7.8% vs. 8.3%), were also comparable (all p > 0.70) between switch and nonswitch cohorts.

Conclusions:

Long‐term infliximab persistence was similar between switch and nonswitch cohorts over 4 years of follow‐up. These data represent the longest duration of “real‐world” follow‐up, and should provide further reassurance that nonmedical switching is safe and clinically comparable to ongoing originator infliximab in clinically stable patients with IBD.

A real-world, observational, prospective cohort study evaluating the safety and effectiveness of CT-P13 in inflammatory bowel disease and rheumatoid arthritis: the MEGA-J study

Article

Author: Obata, Hirozumi ; Ishida, Tetsuya ; Yokoe, Isamu ; Park, Soyeon ; Nishimata, Nobuaki ; Kim, SooKyoung

OBJECTIVE:

The primary objective of the MEGA-J study (UMIN-CTR number: UMIN000057308) was to assess the safety of CT-P13, an infliximab biosimilar, in Japanese patients with Crohn's disease (CD), ulcerative colitis (UC), and/or rheumatoid arthritis (RA) after switching from reference infliximab.

METHODS:

Data were collected over 5 years, following initiation of CT-P13 treatment within routine clinical practice. Interim findings are reported (cut-off: last patient's Year 2 visit). The primary endpoint was the incidence of uncommon adverse drug reactions (ADRs), including tuberculosis and serious infections.

RESULTS:

Overall, 220 patients were enrolled (123 CD; 74 UC; 23 RA). Forty-eight (39.0%), 37 (50.0%), and 3 (13.0%) patients reported ≥1 uncommon ADR in the CD, UC, and RA groups, respectively. The majority (94.3%) were unrelated to CT-P13. No cases of tuberculosis and one unrelated case of serious infection were reported. Nineteen (8.6%) patients discontinued treatment for reasons related to CT-P13.

CONCLUSIONS:

Overall, CT-P13 was well tolerated, demonstrating the safety of long-term treatment in real-world practice.

Factors associated with anti-drug antibody production in ankylosing spondylitis patients treated with the infliximab biosimilar CT-P13

Article

Author: Kim, Yongbum ; Jo, Sungsin ; Shin, Ji-Hui ; Nam, Bora ; Choi, Nayeon ; Kim, Tae-Hwan

Objective:

CT-P13, a biosimilar of infliximab, is widely used for treating ankylosing spondylitis (AS). However, the formation of anti-drug antibodies (ADAs) can reduce its efficacy. This study aimed to identify risk factors associated with high ADA levels in AS patients treated with CT-P13.

Methods:

A prospective observational study enrolled patients with intravenous CT-P13. Clinical data and disease activity was assessed at baseline, 24 weeks, and 54 weeks after CT-P13 treatment. Blood concentrations of CT-P13 and ADAs were measured at 24 and 54 weeks, and their correlation was investigated. Patients were grouped by ADA levels at 54 weeks. Univariable and multivariable logistic regression identified factors associated with high ADA concentrations.

Results:

A total of 34 patients was enrolled. Significant decreases in Bath Ankylosing Spondylitis Disease Activity Index and Bath Ankylosing Spondylitis Functional Index scores were observed relative to baseline after 24 weeks of CT-P13 therapy. Serum concentrations of CT-P13 and ADA levels increased following treatment. The median serum CT-P13 concentration was 17.6 [12.8, 22.7] µg/mL at 24 weeks and 23.5 [11.7, 34.2] µg/mL at 54 weeks. ADA levels were 6.7 [6.5, 9.1] AU/mL at 24 weeks and 11.4 [9.0, 28.4] AU/mL at 54 weeks. The serum concentrations of CT-P13 and ADA exhibited a negative correlation. In multivariable analysis, current smoking was associated with high ADA production at 54 weeks.

Conclusion:

Smoking is identified as a significant risk factor for elevated ADAs in AS patients treated with CT-P13. The findings underscore the importance of smoking-cessation strategies in the management of AS patients.

Celltrion's YUFLYMA® (adalimumab-aaty) receives FDA interchangeability designation for all its approved dosage forms and strengths

YUFLYMA ® (adalimumab-aaty) is a high-concentration (100mg/mL) and citrate-free formulation of Humira ® (adalimumab) biosimilar[1] Celltrion previously received interchangeability (IC) designation for YUFLYMA® (adalimumab-aaty) in prefilled syringes (20mg & 80mg); Expanded interchangeability (IC) designation applies to prefilled syringe (40mg) and autoinjectors (40mg and 80mg) INCHEON, South Korea, May 21, 2025 /PRNewswire/ -- Celltrion, Inc. today announced that the U.S. Food and Drug Administration (FDA) has granted an expanded interchangeable designation for YUFLYMA ® (adalimumab-aaty), now including prefilled syringe (40mg) and autoinjectors (40mg and 80mg) presentations. With this approval, YUFLYMA is now fully interchangeable with the reference product, Humira ® (adalimumab), across all marketed dosage forms and strengths. YUFLYMA is a high-concentration, citrate-free biosimilar to Humira, approved for multiple inflammatory indications including rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), ulcerative colitis (UC), plaque psoriasis (Ps), hidradenitis suppurativa (HS), and uveitis (UV) in adult patients; Crohn's disease (CD) in adults and pediatric patients 6 years of age and older; and juvenile idiopathic arthritis (JIA) in patients 2 years of age and older.[1] "This full interchangeability designation comes at a pivotal time as Celltrion continues to lead in the evolving biosimilar landscape," said Thomas Nusbickel, Chief Commercial Officer at Celltrion USA. "In alignment with recent federal initiatives aimed at lowering drug costs, we've taken timely action to enhance patient access and affordability. YUFLYMA – a high-concentration, citrate-free adalimumab biosimilar now fully interchangeable with Humira – reflects our long-standing commitment to delivering high-quality, accessible treatment options. Going forward, Celltrion will continue to put patients first by keeping drug costs affordable and remaining at the forefront of the U.S. biosimilar market, bringing competitive pricing and high-quality, accessible treatment options." The interchangeable designation builds on the Phase III interchangeability study, which demonstrated similar outcomes in terms of pharmacokinetics, efficacy, safety and immunogenicity in patients with moderately to severely active plaque psoriasis who received reference adalimumab (ADA) continuously and those who alternated between reference ADA and YUFLYMA during the dosing interval of Weeks 25-27. The result of the interchangeability study was presented at the European Academy of Dermatology & Venereology (EADV), September 2024, in the Netherlands.[2] The expanded interchangeability designation for YUFLYMA is complemented by a strategic price reduction that reflects Celltrion's ongoing commitment to improving patient access while aligning with federal efforts to lower drug prices. Effective immediately, the wholesale acquisition cost (WAC) list price of YUFLYMA has been reduced to $948 per syringe, and the updated pricing has been uploaded to the national pricing compendia. YUFLYMA was first introduced in the U.S. market in July 2023 and is currently available as a 20mg, 40mg, and 80mg solution for injection in prefilled syringes and as 40mg and 80mg in autoinjectors. Celltrion offers adalimumab-aaty in both branded and unbranded versions, with two pricing options to meet different patient needs and improve patient affordability. Notes to Editors: About YUFLYMA® (CT-P17, biosimilar adalimumab-aaty)[1] YUFLYMA is a high-concentration, low-volume and citrate-free adalimumab biosimilar to receive European Commission approval. YUFLYMA is FDA approved for the treatment of patients with rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, plaque psoriasis, hidradenitis suppurativa and uveitis. YUFLYMA has been designated by the FDA as an interchangeable biosimilar in a prefilled syringe and autoinjector. YUFLYMA is a recombinant fully human anti–tumor necrosis factor α (anti-TNFα) monoclonal antibody. YUFLYMA is available in prefilled syringe as 20mg/0.2mL, 40mg/0.4mL and 80mg/0.8mL and autoinjector as 40mg/0.4mL and 80mg/0.8mL. Additionally, YUFLYMA features one of the longest shelf lives in its class, maintaining stability at room temperature (77 °F, 25 °C) for up to 31 days. IMPORTANT SAFETY INFORMATION[1] This important safety information also applies to YUFLYMA® (adalimumab-aaty). SERIOUS INFECTIONS Patients treated with adalimumab-aaty 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 adalimumab-aaty 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 adalimumab-aaty use and during therapy. Initiate treatment for latent TB prior to adalimumab-aaty 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 antifungal 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 adalimumab-aaty 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 adalimumab-aaty, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy. Treatment with adalimumab-aaty should not be initiated in patients with an active infection, including localized infections. Patients over 65 years of age, patients with co-morbid conditions and/or patients taking concomitant immunosuppressants (such as corticosteroids or methotrexate), may be at greater risk of infection. Discontinue adalimumab-aaty if a patient develops a serious infection or sepsis. For a patient who develops a new infection during treatment with adalimumab-aaty, 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 adalimumab-aaty 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 adalimumab-aaty and other biologic products for the treatment of RA, PsA, AS, CD, UC, PS, and HS. Concomitant administration of adalimumab-aaty with other biologic disease-modifying antirheumatic drugs (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. A higher rate of serious infections has been observed in RA patients treated with rituximab who received subsequent treatment with a TNF blocker. MALIGNANCY Lymphoma 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 the 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 adalimumab-aaty 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 controlled portions of clinical trials of some adalimumab products, more cases of malignancies have been observed compared to control-treated adult patients. NMSC was reported during clinical trials for patients treated with adalimumab products. During the controlled portions of 39 global adalimumab clinical trials in adult patients with RA, PsA, AS, CD, UC, PS, HS and UV, the rate (95% confidence interval) of NMSC was 0.8 (0.52, 1.09) per 100 patient-years among adalimumab-treated patients and 0.2 (0.10, 0.59) per 100 patient-years among control-treated patients. Examine all patients, particularly those with a medical history of prior prolonged immunosuppressant therapy or psoriasis patients with a history of psoralen + ultraviolet light A (PUVA) treatment, for the presence of NMSC prior to and during treatment with adalimumab-aaty. In clinical trials of some adalimumab products, there was an approximately threefold higher rate of lymphoma than expected 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 (up to severalfold) than the general population for the development of lymphoma, even in the absence of TNF blockers. Postmarketing cases of acute and chronic leukemia were reported with the use of a TNF blocker in RA and other indications. Approximately half of the postmarketing cases of malignancies in children, adolescents, and young adults receiving adalimumab were lymphomas; 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 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 adalimumab-aaty and institute appropriate therapy. HEPATITIS B VIRUS REACTIVATION Use of TNF blockers, including adalimumab-aaty, 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 closely monitor such patients for clinical and laboratory signs of active HBV infection throughout therapy and for several months following termination of therapy. In patients who develop HBV reactivation, stop adalimumab-aaty and initiate effective antiviral 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 adalimumab-aaty 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 (MS) and optic neuritis, and peripheral demyelinating disease, including Guillain-Barré syndrome. Exercise caution in considering the use of adalimumab-aaty in patients with preexisting or recent-onset central or peripheral nervous system demyelinating disorders; discontinuation of adalimumab-aaty 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 blocking agents. Adverse reactions of the hematologic system, including medically significant cytopenia, have been infrequently reported with adalimumab products. Consider discontinuation of adalimumab-aaty therapy in patients with confirmed significant hematologic abnormalities. 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. Exercise caution when using adalimumab-aaty in patients who have heart failure and monitor them 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 adalimumab-aaty, discontinue treatment. IMMUNIZATIONS Patients on adalimumab-aaty may receive concurrent vaccinations, except for live vaccines. 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 adalimumab-aaty therapy. No data are available on the secondary transmission of infection by live vaccines in patients receiving adalimumab products. The safety of administering live or live-attenuated vaccines in infants exposed to adalimumab 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.

ZYMFENTRA blocks the action of tumor necrosis factor-alpha (TNF-alpha), a protein that can be overproduced in response to certain diseases and cause the immune system to attack normal, healthy parts of the body. ZYMFENTRA was approved by the FDA through the Biologics License Application (BLA) under the 351 (a) pathway of the Public Health Service Act (a "stand-alone" BLA). ZYMFENTRA is considered a new biologic with a first-approved subcutaneous administration form and thus will be under patent protection for its dosage form by 2037 and for its route of administration by 2040. Indication and Important Safety Information ZYMFENTRA® is a prescription medicine indicated in adults for maintenance treatment of: Moderately-to-severely active Crohn's disease following treatment with an infliximab product administered intravenously. Moderately-to-severely active ulcerative colitis following treatment with an infliximab product administered intravenously. Moderately-to-severely active ulcerative colitis following treatment with an infliximab product administered intravenously. It is not known if ZYMFENTRA is safe and effective in children under 18 years of age. What is the most important information I should know about ZYMFENTRA? SERIOUS INFECTIONS Patients treated with ZYMFENTRA are at increased risk for developing serious infections involving various organ systems and sites that may lead to hospitalization or death. Discontinue ZYMFENTRA if a patient develops a serious infection or sepsis. Reported infections include: Active tuberculosis (TB), including reactivation of latent TB. Patients frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent TB before and during treatment with ZYMFENTRA. Treatment for latent infection should be initiated prior to treatment with ZYMFENTRA. Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients may present with disseminated, rather than localized, disease. Empiric anti-fungal therapy should be considered 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. Bacterial, viral, and other infections due to opportunistic pathogens, including Legionella and Listeria. The risks and benefits of treatment with ZYMFENTRA should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection. Closely monitor patients for the development of signs and symptoms of infection during and after treatment with ZYMFENTRA, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy. Risk of infection may be higher in patients greater than 65 years of age, patients with comorbid conditions and/or patients taking concomitant immunosuppressant therapy. In clinical trials, other serious infections observed in patients treated with infliximab included arthritis bacterial, pneumonia, and urinary tract infection. MALIGNANCIES Malignancies, some fatal, have been reported in children, adolescents, and young adults treated with TNF blockers, including infliximab products. Approximately half of these cases were lymphomas, including Hodgkin's and non-Hodgkin's lymphoma. The other cases represented a variety of malignancies, including rare malignancies that are usually associated with immunosuppression and malignancies that are not usually observed in children and adolescents. The malignancies occurred after a median of 30 months after the first dose of therapy. Most of the patients were receiving concomitant immunosuppressants. Post-marketing cases of hepatosplenic T-cell lymphoma, a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers, including infliximab products. These cases have had a very aggressive disease course and have been fatal. The majority of reported cases have occurred in patients with Crohn's disease or ulcerative colitis, and most 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. Carefully assess the risks and benefits of treatment with ZYMFENTRA, especially in these patient types. In clinical trials of all TNF blockers, more cases of malignancies were observed compared with controls and the expected rate in the general population. In clinical trials of some TNF blockers, including infliximab products, more cases of other malignancies were observed compared with controls. As the potential role of TNF blocker therapy in the development of malignancies is not known, caution should be exercised when considering treatment of patients with a current or a past history of malignancy. Melanoma and Merkel cell carcinoma have been reported in patients treated with TNF blocker therapy, including infliximab products. Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. CONTRAINDICATIONS ZYMFENTRA is contraindicated in patients with a previous severe hypersensitivity reaction to infliximab-dyyb, other infliximab products, any of the inactive ingredients of ZYMFENTRA or any murine proteins (severe hypersensitivity reactions have included anaphylaxis, hypotension and serum sickness). HEPATITIS B VIRUS REACTIVATION TNF blockers, including infliximab products, have been associated with reactivation of hepatitis B virus (HBV) in patients who are chronic carriers. Some cases were fatal. Patients should be tested for HBV infection before initiating ZYMFENTRA. For patients who test positive, consult a physician with expertise in the treatment of hepatitis B. Exercise caution when prescribing ZYMFENTRA for patients identified as carriers of HBV and monitor closely for active HBV infection during and following termination of therapy with ZYMFENTRA. Discontinue ZYMFENTRA in patients who develop HBV reactivation and initiate antiviral therapy with appropriate supportive treatment. Exercise caution when considering resumption of ZYMFENTRA and monitor patients closely. HEPATOTOXICITY Hepatobiliary disorders, including acute liver failure, jaundice abnormal hepatic function, hepatic steatosis, hepatitis, hepatotoxicity, hyperbilirubinemia and non-alcoholic fatty liver, have been reported in patients receiving infliximab products post-marketing. Some cases were fatal or required liver transplant. Aminotransferase elevations were not noted prior to discovery of liver injury in many cases. Patients with symptoms or signs of liver dysfunction should be evaluated for evidence of liver injury. If jaundice and/or marked liver enzyme elevations (eg, ≥5 times the upper limit of normal) develop, ZYMFENTRA should be discontinued and a thorough investigation of the abnormality should be undertaken. CONGESTIVE HEART FAILURE Cases of worsening congestive heart failure (CHF) and new onset CHF have been reported with TNF blockers. Some cases had a fatal outcome. In several exploratory trials of other TNF blockers in the treatment of CHF, there were greater proportions of TNF-blocker-treated patients who had CHF exacerbations requiring hospitalization or increased mortality. ZYMFENTRA has not been studied in patients with a history of CHF and ZYMFENTRA should be used with caution in patients with CHF. HEMATOLOGIC REACTION Cases of leukopenia, neutropenia, thrombocytopenia and pancytopenia (some fatal) have been reported. The causal relationship to infliximab-product therapy remains unclear. Exercise caution in patients who have ongoing or a history of significant hematologic abnormalities. Advise patients to seek immediate medical attention if they develop signs and symptoms of blood dyscrasias or infection. Consider discontinuation of ZYMFENTRA in patients who develop significant hematologic abnormalities. HYPERSENSITIVITY AND OTHER ADMINISTRATION REACTIONS In post-marketing experience, serious systemic hypersensitivity reactions (including anaphylaxis, hypotension and serum sickness) have been reported following administration of infliximab products. If an anaphylactic or other clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue ZYMFENTRA. INJECTION SITE REACTIONS In clinical studies, localized injection-site reactions were reported following administration of ZYMFENTRA. If a clinically significant injection-site reaction occurs, institute appropriate therapy and discontinue ZYMFENTRA. NEUROLOGIC REACTIONS Agents that inhibit TNF have been associated with central nervous system (CNS) manifestation of systemic vasculitis, seizure and new onset or exacerbation of CNS demyelinating disorders, including multiple sclerosis and optic neuritis and peripheral demyelinating disorders, including Guillain-Barré syndrome. Exercise caution when considering ZYMFENTRA in patients with these disorders and consider discontinuation if these disorders develop. RISK OF INFECTION WITH CONCURRENT ADMINISTRATION OF OTHER BIOLOGICS PRODUCTS Serious infections and neutropenia have been reported with concurrent use of ZYMFENTRA with other immunosuppressive biological products. The concurrent use of ZYMFENTRA with other immunosuppressive biological products used to treat UC and CD may increase the risk of infection and is not recommended. RISK OF ADDITIVE IMMUNOSUPPRESSIVE EFFECTS FROM PRIOR BIOLOGICAL PRODUCTS Consider the half-life and mode of action of prior biological products to avoid unintended additive immunosuppressive effects when initiating ZYMFENTRA. AUTOIMMUNITY Treatment with TNF blockers may result in the formation of autoantibodies and in the development of a lupus-like syndrome. Discontinue ZYMFENTRA treatment if symptoms of a lupus-like syndrome develop. VACCINATIONS AND USE OF LIVE VACCINES/THERAPEUTIC INFECTIOUS AGENTS Prior to initiating ZYMFENTRA, update vaccinations in accordance with current vaccination guidelines. Live vaccines or therapeutic infectious agents should not be given with ZYMFENTRA due to the possibility of clinical infections, including disseminated infections. At least a 6-month waiting period following birth is recommended before the administration of any live vaccine to infants exposed in utero to ZYMFENTRA. ADVERSE REACTIONS In clinical trials with ZYMFENTRA, the most common adverse reactions occurring in ≥3% of ZYMFENTRA-treated patients included site reactions, COVID-19, anemia, arthralgia, infection site reaction, increased alanine aminotransferase and abdominal pain for UC, and COVID-19, headache, upper respiratory tract infection, injection site reaction, diarrhea, increased blood creatine phosphokinase, arthralgia, increased alanine aminotransferase, hypertension, urinary tract infection, neutropenia, dizziness and leukopenia for CD.

U.S. FDA grants interchangeable designation to YUFLYMA® (adalimumab-aaty), Celltrion's biosimilar to Humira® (adalimumab)

YUFLYMA ® (adalimumab-aaty) is a high-concentration (100mg/mL) and citrate-free formulation of Humira ® (adalimumab) biosimilar, that is now interchangeable [1] Interchangeable designation of YUFLYMA ® is supported by positive data from the Phase III interchangeability study in patients with moderate-to-severe plaque psoriasis INCHEON, South Korea, April 14, 2025 /PRNewswire/ -- Celltrion, Inc. today announced that the U.S. Food and Drug Administration (FDA) has designated YUFLYMA ® (adalimumab-aaty), as an interchangeable biosimilar to Humira ® (adalimumab). YUFLYMA is an FDA-approved, high-concentration (100mg/mL) and citrate-free formulation of Humira® biosimilar, approved for multiple inflammatory indications.[1] "With this new designation, YUFLYMA is further positioned to help more patients gain access to and afford the therapy they need," said Thomas Nusbickel, Chief Commercial Officer at Celltrion USA. "YUFLYMA has the same dosage form, route of administration, and dosing regimen as the reference product. The pharmacist's ability to substitute the biosimilar directly at the pharmacy without the hassle of a new prescription and without the patient having to learn a new method of administration can be a game changer in increasing patient access to adalimumab." The interchangeable designation was supported by data from the Phase III interchangeability study, which demonstrated similar outcomes in terms of pharmacokinetics, efficacy, safety and immunogenicity in patients with moderately to severely active plaque psoriasis who received reference adalimumab (ADA) continuously and those who alternated between reference ADA and YUFLYMA during the dosing interval of Week 25-27. The result of the interchangeability study was presented at the European Academy of Dermatology & Venereology (EADV) 2024.[2] FDA-approved interchangeable biosimilars may be substituted for the reference product at the pharmacy without the intervention of the prescribing health care provider, subject to state laws.[3] The high-concentration form of YUFLYMA was FDA-approved in May 2023 and is currently available as 20mg, 40 mg and 80mg solution for injection in a prefilled syringe and in an autoinjector pen. YUFLYMA was introduced into the US commercial market on July 2, 2023. YUFLYMA is available in two pricing options to help provide more affordable options for patients. Adalimumab-aaty, the unbranded version, is priced at an 85% discount to the current wholesale acquisition cost (WAC) list price of Humira (adalimumab), providing economic benefits for patients and overall healthcare system. The branded version is priced at a 5% discount to the current WAC of Humira (adalimumab). Notes to Editors: About YUFLYMA® (CT-P17, biosimilar adalimumab-aaty)[1] YUFLYMA is the world's first proposed high-concentration, low-volume and citrate-free adalimumab biosimilar to receive European Commission approval. YUFLYMA is FDA approved for the treatment of patients with rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, plaque psoriasis, hidradenitis suppurativa and uveitis. YUFLYMA has been designated by the FDA as an interchangeable biosimilar in a prefilled syringe. YUFLYMA is a recombinant fully human anti–tumor necrosis factor α (anti-TNFα) monoclonal antibody. YUFLYMA is available in 20mg/0.2mL, 40mg/0.4mL and 80mg/0.8mL. IMPORTANT SAFETY INFORMATION[1] This important safety information also applies to YUFLYMA® (adalimumab-aaty) SERIOUS INFECTIONS Patients treated with adalimumab-aaty 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 adalimumab-aaty 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 adalimumab-aaty use and during therapy. Initiate treatment for latent TB prior to adalimumab-aaty 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 antifungal 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 adalimumab-aaty 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 adalimumab-aaty, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy. Treatment with adalimumab-aaty should not be initiated in patients with an active infection, including localized infections. Patients over 65 years of age, patients with co-morbid conditions and/or patients taking concomitant immunosuppressants (such as corticosteroids or methotrexate), may be at greater risk of infection. Discontinue adalimumab-aaty if a patient develops a serious infection or sepsis. For a patient who develops a new infection during treatment with adalimumab-aaty, 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 adalimumab-aaty 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 adalimumab-aaty and other biologic products for the treatment of RA, PsA, AS, CD, UC, PS, and HS. Concomitant administration of adalimumab-aaty 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. A higher rate of serious infections has been observed in RA patients treated with rituximab who received subsequent treatment with a TNF blocker. MALIGNANCY Lymphoma 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 the 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 adalimumab-aaty 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 controlled portions of clinical trials of some adalimumab products, more cases of malignancies have been observed compared to control-treated adult patients. Non-melanoma skin cancer (NMSC) was reported during clinical trials for patients treated with adalimumab products. During the controlled portions of 39 global adalimumab clinical trials in adult patients with RA, PsA, AS, CD, UC, PS, HS and UV, the rate (95% confidence interval) of NMSC was 0.8 (0.52, 1.09) per 100 patient-years among adalimumab-treated patients and 0.2 (0.10, 0.59) per 100 patient-years among control-treated patients. Examine all patients, particularly those 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 adalimumab-aaty. In clinical trials of some adalimumab products, there was an approximately threefold higher rate of lymphoma than expected 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 (up to severalfold) than the general population for the development of lymphoma, even in the absence of TNF blockers. Postmarketing cases of acute and chronic leukemia were reported with the use of a TNF blocker in RA and other indications. Approximately half of the postmarketing cases of malignancies in children, adolescents, and young adults receiving adalimumab were lymphomas; 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 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 adalimumab-aaty and institute appropriate therapy. HEPATITIS B VIRUS REACTIVATION Use of TNF blockers, including adalimumab-aaty, 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 closely monitor such patients for clinical and laboratory signs of active HBV infection throughout therapy and for several months following termination of therapy. In patients who develop HBV reactivation, stop adalimumab-aaty and initiate effective antiviral 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 adalimumab-aaty 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 (MS) and optic neuritis, and peripheral demyelinating disease, including Guillain-Barré syndrome. Exercise caution in considering the use of adalimumab-aaty in patients with preexisting or recent-onset central or peripheral nervous system demyelinating disorders; discontinuation of adalimumab-aaty 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 blocking agents. Adverse reactions of the hematologic system, including medically significant cytopenia, have been infrequently reported with adalimumab products. Consider discontinuation of adalimumab-aaty therapy in patients with confirmed significant hematologic abnormalities. 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. Exercise caution when using adalimumab-aaty in patients who have heart failure and monitor them 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 adalimumab-aaty, discontinue treatment. IMMUNIZATIONS Patients on adalimumab-aaty may receive concurrent vaccinations, except for live vaccines. 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 adalimumab-aaty therapy. No data are available on the secondary transmission of infection by live vaccines in patients receiving adalimumab products. The safety of administering live or live-attenuated vaccines in infants exposed to adalimumab 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 Adalimumab-aaty is a tumor necrosis factor (TNF) blocker indicated for: Rheumatoid Arthritis (RA): 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 RA Juvenile Idiopathic Arthritis (JIA): reducing signs and symptoms of moderately to severely active polyarticular JIA in patients 2 years of age and older Psoriatic Arthritis (PsA): reducing signs and symptoms, inhibiting the progression of structural damage, and improving physical function in adult patients with active PsA Ankylosing Spondylitis (AS): reducing signs and symptoms in adult patients with active AS Crohn's Disease (CD): treatment of moderately to severely active Crohn's disease in adults and pediatric patients 6 years of age and older Ulcerative Colitis (UC): treatment of moderately to severely active ulcerative colitis in adults Limitations of Use: Effectiveness has not been established in patients who have lost response to or were intolerant to TNF blockers Plaque Psoriasis (Ps): 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 Hidradenitis Suppurativa (HS): treatment of adult patients with moderate to severe hidradenitis suppurativa Uveitis (UV): treatment of non-infectious intermediate, posterior, and panuveitis in adult patients For Yuflyma (adalimumab-aaty): Please click for Full U.S. Prescribing Information.
