For more information, please visit: . About ZYMFENTRA® (infliximab-dyyb) [1] ZYMFENTRA is a prescription medicine used as an injection under the skin (subcutaneous injection) by adults for the maintenance treatment of: moderately to severely active ulcerative colitis following treatment with an infliximab product given by intravenous infusion (IV), moderately to severely active Crohn's disease following treatment with an infliximab product given by intravenous infusion (IV). 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® (infliximab-dyyb) 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. 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. 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.

Evidence demonstrates that SUBLOCADE supports long-term recovery from opioid use disorder (OUD) and is effective and safe. Publications highlight the importance of overcoming access barriers to long-acting injectable treatments for OUD RICHMOND, Va., Oct. 30, 2024 /PRNewswire/ -- Indivior PLC (Nasdaq/LSE: INDV), in recognizing Substance Abuse Prevention Month, provides an update on key findings from the last year that demonstrate the importance of access to medications for the treatment of opioid use disorder (MOUD) and the effectiveness and safety of SUBLOCADE® in the treatment of OUD. These data add to the growing body of evidence that SUBLOCADE can improve outcomes, such as abstinence, retention, and recovery in persons with OUD. Publications In a post hoc analysis of the SUBLOCADE randomized, double-blind, placebo-controlled phase 3 clinical trial, published in Harm Reduction Journal, SUBLOCADE 300 mg maintenance dose resulted in a statistically significant increase in abstinence from opioids among study participants with OUD who injected opioids compared to 100 mg maintenance dose. However, both were equally effective in non-injecting participants. Results from the Community Long-Acting Buprenorphine (CoLAB) Study, a prospective single-arm, multicenter, open label trial in Australia, were published in the International Journal of Drug Policy, and demonstrated that participants could be maintained on SUBLOCADE treatment for 96 weeks with continuous improvements in abstinence, depression, quality of life and medication satisfaction. In a qualitative research survey of 20 participants representing various practice settings, published in American Health & Drug Benefits, it was determined that telemedicine was the most common solution adopted during the COVID-19 pandemic to overcome access barriers. However, today there are still significant challenges in ensuring appropriate access to medications for those living with OUD and continued support, effective solutions and policies in the United States, need to be continually addressed. In a narrowly focused literature, policy, and legal proceedings review, published in Corrections Today, a clear disparity in access to MOUD was found between the general public and incarcerated individuals. Stigma and informed consent were the most discussed barriers used to justify policies limiting MOUD for incarcerated individuals. Presentations Multiple real-world evidence poster presentations highlight challenges and opportunities in treating persons with OUD. 2024 American Association of Psychiatric Pharmacists, April 7-10, Orlando FL Title: Emergency Room (ER) Visits Among Opioid Use Disorder (OUD) Patients Title: Opioid Treatment Programs, Healthcare Resource Utilization, and Healthcare Costs among Patients Initiating Treatment with Buprenorphine Extended-Release 2024 American Telemedicine Association Nexus, May 5-7, Phoenix AZ Title: Impact of Telemedicine on Medication for Opioid Use Disorder Retention during the SARS-CoV-2 Pandemic Period Among Patients with OUD 2024 College on Problems of Drug Dependence, June 15-19, Montreal Quebec Canada Title: Buprenorphine Treatment After an Emergency Department Visit for Non-Fatal Opioid Overdose Title: Pain Predicts Abstinence During Treatment of Opioid Use Disorder for Individuals Reporting Moderate to Severe Pain Title: A Randomized Open-Label Study Comparing Rapid and Standard Inductions to Injectable Buprenorphine Extended-Release (BUP-XR) Treatment Title: A Mechanistic Pharmacological Model to Predict and Inform Effective Buprenorphine Treatment Induction Strategies in the Era of Synthetic Opioids 2024 U.S. Public Health Service Scientific & Training Symposium, June 24-27, Jacksonville FL Title: Clinical and Treatment Characteristics of American Indian/Alaska Native Patients Managing Opioid Use Disorder Compared to the General US Population BUPE2024 – Buprenorphine in Medicine: Clinical and Public Policy Implications, August 5, Virtual conference Title: Healthcare Utilization and Costs Associated with Management of Opioid Use Disorder (OUD) within Residential Treatment Programs (RTP) and Office-Based Opioid Treatment Programs (OBOT) 2024 National Commission on Correctional Health Care (NCCHC) Annual, October 19-23, Las Vegas, NV Title: Outcomes Associated with Medications for Opioid Use Disorder in the Carceral System: A Systematic Literature Review Title: Diversion of Medications for OUD in the Criminal Justice System Dr. Christian Heidbreder, Ph.D., Chief Scientific Officer at Indivior, emphasized, "The collective evidence highlights the importance of access to Medications for OUD, such as SUBLOCADE, in reducing barriers to adherence and improving outcomes for individuals in recovery. Indivior is committed to continuing to advance the understanding of patients with OUD, educate on evidence-based practices, overcome stigma, and focus on recovery outcomes." Among the almost 6 million people aged 12 or older with a past year opioid use disorder in 2023, only 18% (or one million people) received treatment through MOUD.1 About SUBLOCADE® SUBLOCADE ® (buprenorphine extended-release) injection, for subcutaneous use, CIII INDICATION AND HIGHLIGHTED SAFETY INFORMATION INDICATION SUBLOCADE is indicated for the treatment of moderate to severe opioid use disorder in patients who have initiated treatment with a buprenorphine-containing product, followed by dose adjustment for a minimum of 7 days. SUBLOCADE should be used as part of a complete treatment plan that includes counseling and psychosocial support. HIGHLIGHTED SAFETY INFORMATION WARNING: RISK OF SERIOUS HARM OR DEATH WITH INTRAVENOUS ADMINISTRATION; SUBLOCADE RISK EVALUATION AND MITIGATION STRATEGY Serious harm or death could result if administered intravenously. SUBLOCADE forms a solid mass upon contact with body fluids and may cause occlusion, local tissue damage, and thrombo-embolic events, including life threatening pulmonary emboli, if administered intravenously. Because of the risk of serious harm or death that could result from intravenous self-administration, SUBLOCADE is only available through a restricted program called the SUBLOCADE REMS Program. Healthcare settings and pharmacies that order and dispense SUBLOCADE must be certified in this program and comply with the REMS requirements. CONTRAINDICATIONS SUBLOCADE should not be administered to patients who have been shown to be hypersensitive to buprenorphine or any component of Indivior's proprietary buprenorphine gel depot delivery system. WARNINGS AND PRECAUTIONS Addiction, Abuse, and Misuse: SUBLOCADE contains buprenorphine, a Schedule III controlled substance that can be abused in a manner similar to other opioids. Monitor patients for conditions indicative of diversion or progression of opioid dependence and addictive behaviors. Respiratory Depression: Life threatening respiratory depression and death have occurred in association with buprenorphine. Warn patients of the potential danger of self-administration of benzodiazepines or other CNS depressants while under treatment with SUBLOCADE. Opioids can cause sleep-related breathing disorders e.g., central sleep apnea (CSA), sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. Consider decreasing the opioid using best practices for opioid taper if CSA occurs. Strongly consider prescribing naloxone at SUBLOCADE initiation or renewal because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose. Educate patients and caregivers on how to recognize respiratory depression and how to treat with naloxone if prescribed. Risk of Serious Injection Site Reactions: The most common injection site reactions are pain, erythema and pruritus with some involving abscess, ulceration, and necrosis. The likelihood of serious injection site reactions may increase with inadvertent intramuscular or intradermal administration. Neonatal Opioid Withdrawal Syndrome: Neonatal opioid withdrawal syndrome is an expected and treatable outcome of prolonged use of opioids during pregnancy. Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off the opioid. Risk of Opioid Withdrawal With Abrupt Discontinuation: If treatment with SUBLOCADE is discontinued, monitor patients for several months for withdrawal and treat appropriately. Risk of Hepatitis, Hepatic Events: Monitor liver function tests prior to and during treatment. Risk of Withdrawal in Patients Dependent on Full Agonist Opioids: Verify that patient is clinically stable on transmucosal buprenorphine before injecting SUBLOCADE. Treatment of Emergent Acute Pain: Treat pain with a non-opioid analgesic whenever possible. If opioid therapy is required, monitor patients closely because higher doses may be required for analgesic effect. ADVERSE REACTIONS Adverse reactions commonly associated with SUBLOCADE (in ≥5% of subjects) were constipation, headache, nausea, injection site pruritus, vomiting, increased hepatic enzymes, fatigue, and injection site pain.

Pivotal LIBERTY studies (LIBERTY-CD and LIBERTY-UC) previously demonstrated superior efficacy of subcutaneous (SC) infliximab over placebo for maintenance therapy in patients with Crohn's disease (CD) and ulcerative colitis (UC)[1], [2] ZYMFENTRA® is the first and only FDA-approved subcutaneous infliximab Late-breaking post hoc analysis of the LIBERTY studies suggests no meaningful differences in efficacy and safety outcomes at week 54 and 102 weeks between monotherapy and combination therapy of SC infliximab with immunosuppressants[3] JERSEY CITY, N.J., Oct. 29, 2024 /PRNewswire/ -- Celltrion USA today announced a late-breaking post hoc analysis of the pivotal LIBERTY studies (LIBERTY-CD and LIBERTY-UC) of ZYMFENTRA® (infliximab-dyyb), during the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting. The data demonstrate that clinical outcomes for patients treated with ZYMFENTRA monotherapy were comparable to those for patients on combination therapy with immunosuppressants (IS), suggesting that monotherapy could be a potential treatment option for patients with inflammatory bowel disease (IBD).[3] One-year data for the LIBERTY studies were originally published in the journal Gastroenterology.[4] ZYMFENTRA, the first and only FDA-approved subcutaneous infliximab, had previously shown superior efficacy over placebo for maintenance therapy in patients with Crohn's disease (CD) and ulcerative colitis (UC) in the randomized LIBERTY-CD and LIBERTY-UC studies.[1], [2] The new post hoc analysis explored the impact of baseline IS use by comparing outcomes between monotherapy and combination therapy.[3] The analysis included 429 patients from the CD and UC cohorts across the LIBERTY studies (192 patients with CD [monotherapy, n=126; combination therapy, n=66] and 237 patients with UC [monotherapy, n=180; combination therapy, n=57]). In both studies, there were no meaningful differences in efficacy outcomes between monotherapy and combination therapy at Week 54 or Week 102, despite combination therapy generally showing higher mean trough levels of infliximab after Week 10. Additionally, the overall safety profile was comparable between monotherapy and combination therapy throughout the pooled maintenance and extension phase.[3] "The new data strengthens the case for ZYMFENTRA monotherapy as a potential treatment option for patients with Crohn's disease and ulcerative colitis," said Hetal Patel, PharmD MBA, Head of Medical Affairs at Celltrion USA. "At Celltrion, we are committed to offering therapies that help patients and healthcare providers make informed, personalized treatment decisions. These findings suggest that ZYMFENTRA could offer flexibility in treatment approaches, providing confidence in monotherapy as an alternative to combination therapy, while maintaining effective disease control."

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.
