SERIOUS INFECTIONS

严重感染

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.

使用ZYMFENTRA治疗的患者面临更高的风险，可能会发生涉及多个器官系统和部位的严重感染，这些感染可能导致住院或死亡。如果患者出现严重感染或败血症，应停止使用ZYMFENTRA。

Reported infections include:

报告的感染包括：

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..

活动性结核病（TB），包括潜伏性结核的再激活。患者常表现为播散性或肺外疾病。在使用ZYMFENTRA治疗之前和期间，应检测患者是否存在潜伏性结核。潜伏性感染的治疗应在ZYMFENTRA治疗之前开始。

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..

侵袭性真菌感染，包括组织胞浆菌病、球孢子菌病、念珠菌病、曲霉菌病、芽生菌病和肺孢子虫病。患者可能表现为播散性而非局部性疾病。对于有侵袭性真菌感染风险且出现严重全身性疾病的患者，应考虑经验性抗真菌治疗。

Bacterial, viral, and other infections due to opportunistic pathogens, including Legionella and Listeria.

由包括军团菌和李斯特菌在内的机会性病原体引起的细菌、病毒和其他感染。

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..

在慢性或反复感染患者开始使用ZYMFENTRA治疗之前，应仔细权衡治疗的风险和益处。在ZYMFENTRA治疗期间及之后，密切监测患者是否出现感染的体征和症状，包括在治疗前潜伏性结核病检测呈阴性的患者中可能发生结核病的情况。

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..

年龄大于65岁的患者、有合并症的患者和/或接受伴随免疫抑制治疗的患者感染风险可能更高。在临床试验中，接受英夫利昔单抗治疗的患者中观察到的其他严重感染包括细菌性关节炎、肺炎和尿路感染。

MALIGNANCIES

恶性肿瘤

Malignancies, some fatal, have been reported in children, adolescents, and young adults treated with TNF blockers, including infliximab products.

据报道，使用包括英夫利昔单抗产品在内的TNF抑制剂治疗的儿童、青少年和年轻成人中出现了恶性肿瘤，其中一些是致命的。

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.

大约一半的病例是淋巴瘤，包括霍奇金和非霍奇金淋巴瘤。其他病例则代表了各种各样的恶性肿瘤，包括通常与免疫抑制相关的罕见恶性肿瘤以及通常不会在儿童和青少年中观察到的恶性肿瘤。

The malignancies occurred after a median of 30 months after the first dose of therapy. Most of the patients were receiving concomitant immunosuppressants..

恶性肿瘤发生在首次治疗剂量后的中位30个月后。大多数患者同时接受免疫抑制剂治疗。

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.

在使用包括英夫利昔单抗产品在内的TNF抑制剂治疗的患者中，已有报告发生肝脾T细胞淋巴瘤（一种罕见的T细胞淋巴瘤）的上市后病例。这些病例的病程极为侵袭性，并导致死亡。大多数报告的病例发生在克罗恩病或溃疡性结肠炎患者中，且多数为青少年和年轻成年男性。

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..

几乎所有这些患者在诊断时或之前都曾同时接受过硫唑嘌呤或6-巯基嘌呤与TNF阻滞剂的治疗。仔细评估使用ZYMFENTRA治疗的风险和益处，尤其是在这些患者类型中。

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..

在所有TNF阻滞剂的临床试验中，与对照组及普通人群的预期比率相比，观察到更多的恶性肿瘤病例。在包括英夫利昔单抗产品在内的某些TNF阻滞剂的临床试验中，与其他对照组相比，观察到更多其他类型的恶性肿瘤病例。由于TNF阻滞剂治疗在恶性肿瘤发展中的潜在作用尚不清楚，在考虑对当前或过去有恶性肿瘤病史的患者进行治疗时，应谨慎行事。

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.

据报道，接受包括英夫利昔单抗产品在内的TNF阻滞剂治疗的患者中出现了黑色素瘤和默克尔细胞癌。建议所有患者，特别是具有皮肤癌风险因素的患者，定期进行皮肤检查。

CONTRAINDICATIONS

禁忌症

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).

ZYMFENTRA 禁用于既往对英夫利昔单抗-dyyb、其他英夫利昔单抗产品、ZYMFENTRA 的任何非活性成分或任何鼠源蛋白有严重超敏反应的患者（严重超敏反应包括过敏性休克、低血压和血清病）。

HEPATITIS B VIRUS REACTIVATION

乙型肝炎病毒再激活

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.

包括英夫利昔单抗产品在内的TNF抑制剂，与慢性携带乙型肝炎病毒（HBV）患者的病毒再激活有关。一些病例是致命的。在开始使用ZYMFENTRA之前，应对患者进行HBV感染检测。对于检测呈阳性的患者，请咨询具有乙型肝炎治疗经验的医生。

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.

对确定为乙肝病毒携带者的患者开ZYMFENTRA时应谨慎，并在ZYMFENTRA治疗期间及治疗结束后密切监测活动性乙肝病毒感染情况。对于出现乙肝病毒再激活的患者，应停用ZYMFENTRA，并开始适当的抗病毒治疗和支持治疗。

Exercise caution when considering resumption of ZYMFENTRA and monitor patients closely..

在考虑恢复使用ZYMFENTRA时要谨慎，并密切监测患者。

HEPATOTOXICITY

肝毒性

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.

已有报告指出，接受英夫利昔单抗产品治疗的患者在上市后出现了肝胆疾病，包括急性肝衰竭、黄疸、肝功能异常、脂肪肝、肝炎、肝毒性、高胆红素血症和非酒精性脂肪肝。某些病例导致死亡或需要进行肝脏移植。

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..

在许多情况下，在发现肝损伤之前并未注意到转氨酶升高。出现肝功能障碍症状或体征的患者应评估是否存在肝损伤的证据。如果出现黄疸和/或显著的肝酶升高（例如，≥正常上限的5倍），应停用ZYMFENTRA，并对异常情况进行彻底调查。

CONGESTIVE HEART FAILURE

充血性心力衰竭

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.

已有报告显示，使用肿瘤坏死因子（TNF）抑制剂会导致充血性心力衰竭（CHF）恶化和新发CHF的病例，其中一些病例为致命结局。在其他几种关于TNF抑制剂治疗CHF的探索性试验中，接受TNF抑制剂治疗的患者中有更高比例出现需要住院治疗的CHF加重或死亡率增加的情况。

ZYMFENTRA has not been studied in patients with a history of CHF and ZYMFENTRA should be used with caution in patients with CHF..

ZYMFENTRA 尚未在有充血性心力衰竭（CHF）病史的患者中进行研究，因此 ZYMFENTRA 在充血性心力衰竭（CHF）患者中应谨慎使用。

HEMATOLOGIC REACTION

血液反应

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.

已有报告白细胞减少、中性粒细胞减少、血小板减少和全血细胞减少（部分致命）的病例。其与英夫利昔单抗治疗的因果关系尚不明确。对于持续存在或既往有显著血液学异常的患者，应谨慎使用。若患者出现血液系统疾病或感染的症状和体征，应建议其立即寻求医疗帮助。

Consider discontinuation of ZYMFENTRA in patients who develop significant hematologic abnormalities..

考虑在出现显著血液学异常的患者中停用ZYMFENTRA。

HYPERSENSITIVITY AND OTHER ADMINISTRATION REACTIONS

超敏反应及其他管理反应

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..

在上市后经验中，已有报告指出在使用英夫利昔单抗产品后出现严重的全身性过敏反应（包括过敏性休克、低血压和血清病）。如果发生过敏性反应或其他临床上显著的过敏反应，应采取适当的治疗并停止使用ZYMFENTRA。

INJECTION SITE REACTIONS

注射部位反应

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.

在临床研究中，注射ZYMFENTRA后报告了局部注射部位反应。如果出现有临床意义的注射部位反应，应采取适当的治疗并停止使用ZYMFENTRA。

NEUROLOGIC REACTIONS

神经系统反应

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.

抑制TNF的药物与系统性血管炎、癫痫发作以及中枢神经系统脱髓鞘疾病（包括多发性硬化和视神经炎）的新发或恶化有关，也与周围神经系统脱髓鞘疾病（包括吉兰-巴雷综合征）有关。

Exercise caution when considering ZYMFENTRA in patients with these disorders and consider discontinuation if these disorders develop..

在考虑对这些疾病患者使用ZYMFENTRA时要谨慎，如果这些疾病发作，请考虑停药。

RISK OF INFECTION WITH CONCURRENT ADMINISTRATION OF OTHER BIOLOGICS PRODUCTS

与其他生物制品同时使用时的感染风险

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..

同时使用 ZYMFENTRA 和其他免疫抑制生物制品已报告出现严重感染和中性粒细胞减少。同时使用 ZYMFENTRA 和其他用于治疗 UC 和 CD 的免疫抑制生物制品可能会增加感染风险，因此不建议这样做。

RISK OF ADDITIVE IMMUNOSUPPRESSIVE EFFECTS FROM PRIOR BIOLOGICAL PRODUCTS

既往生物制品的免疫抑制叠加效应风险

Consider the half-life and mode of action of prior biological products to avoid unintended additive immunosuppressive effects when initiating ZYMFENTRA.

在开始使用ZYMFENTRA时，应考虑先前生物制品的半衰期和作用方式，以避免意外的叠加免疫抑制效应。

AUTOIMMUNITY

自身免疫性疾病

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.

使用肿瘤坏死因子（TNF）阻滞剂治疗可能导致自身抗体的形成，并引发类似狼疮综合征的症状。如果出现类似狼疮综合征的症状，请停止使用ZYMFENTRA治疗。

VACCINATIONS AND USE OF LIVE VACCINES/THERAPEUTIC INFECTIOUS AGENTS

疫苗接种和使用活疫苗/治疗性感染因子

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 .

在开始使用ZYMFENTRA之前，应根据当前的疫苗接种指南更新疫苗接种。由于可能存在临床感染，包括播散性感染，因此不应与ZYMFENTRA同时接种活疫苗或使用治疗性感染剂。对于接触过的婴儿，建议在出生后至少等待6个月再接种任何活疫苗。
