WARNINGS AND PRECAUTIONS Serious Infections – do not administer TOFIDENCE during an active infection, including localized infections. If a serious infection develops, interrupt TOFIDENCE until the infection is controlled. ( 5.1 ) Gastrointestinal (GI) perforation—use with caution in patients who may be at increased risk. ( 5.2 ) Hepatotoxicity- Monitor patients for signs and symptoms of hepatic injury. Modify or discontinue TOFIDENCE if abnormal liver tests persist or worsen or if clinical signs and symptoms of liver disease develop. ( 2.8 , 5.3 ) Laboratory monitoring—recommended due to potential consequences of treatment-related changes in neutrophils, platelets, lipids, and liver function tests. ( 2.8 , 5.4 ) Hypersensitivity reactions, including anaphylaxis and death and serious cutaneous reactions including Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) – discontinue TOFIDENCE, treat promptly, and monitor until reaction resolves ( 5.6 ) Live vaccines—Avoid use with TOFIDENCE. ( 5.9 , 7.3 ) 5.1 Serious Infections Serious and sometimes fatal infections due to bacterial, mycobacterial, invasive fungal, viral, protozoal, or other opportunistic pathogens have been reported in patients receiving immunosuppressive agents including tocilizumab products. The most common serious infections included pneumonia, urinary tract infection, cellulitis, herpes zoster, gastroenteritis, diverticulitis, sepsis and bacterial arthritis [see Adverse Reactions (6.1) ]. Among opportunistic infections, tuberculosis, cryptococcus, aspergillosis, candidiasis, and pneumocystosis were reported with tocilizumab products. Other serious infections, not reported in clinical studies, may also occur (e.g., histoplasmosis, coccidioidomycosis, listeriosis). Patients have presented with disseminated rather than localized disease, and were often taking concomitant immunosuppressants such as methotrexate or corticosteroids which in addition to rheumatoid arthritis may predispose them to infections. Do not administer TOFIDENCE in patients with an active infection, including localized infections. The risks and benefits of treatment should be considered prior to initiating TOFIDENCE in patients: with chronic or recurrent infection; who have been exposed to tuberculosis; with a history of serious or an opportunistic infection; who have resided or traveled in areas of endemic tuberculosis or endemic mycoses; or with underlying conditions that may predispose them to infection. Closely monitor patients for the development of signs and symptoms of infection during and after treatment with TOFIDENCE, as signs and symptoms of acute inflammation may be lessened due to suppression of the acute phase reactants [see Dosage and Administration (2.1) , Adverse Reactions (6.1) , and Patient Counseling Information (17) ]. Hold TOFIDENCE if a patient develops a serious infection, an opportunistic infection, or sepsis. A patient who develops a new infection during treatment with TOFIDENCE should undergo a prompt and complete diagnostic workup appropriate for an immunocompromised patient, initiate appropriate antimicrobial therapy, and closely monitor the patient. COVID-19 In patients with COVID-19, monitor for signs and symptoms of new infections during and after treatment with TOFIDENCE. There is limited information regarding the use of tocilizumab products in patients with COVID-19 and concomitant active serious infections. The risks and benefits of treatment with TOFIDENCE in COVID-19 patients with other concurrent infections should be considered. Tuberculosis Evaluate patients for tuberculosis risk factors and test for latent infection prior to initiating TOFIDENCE. In patients with COVID-19, testing for latent infection is not necessary prior to initiating treatment with TOFIDENCE. Consider anti-tuberculosis therapy prior to initiation of TOFIDENCE in patients with a past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent tuberculosis but having risk factors for tuberculosis infection. Consultation with a physician with expertise in the treatment of tuberculosis is recommended to aid in the decision whether initiating anti-tuberculosis therapy is appropriate for an individual patient. Closely monitor patients for the development of signs and symptoms of tuberculosis including patients who tested negative for latent tuberculosis infection prior to initiating therapy. The incidence of tuberculosis in worldwide clinical development programs is 0.1%. Patients with latent tuberculosis should be treated with standard antimycobacterial therapy before initiating TOFIDENCE. Viral Reactivation Viral reactivation has been reported with immunosuppressive biologic therapies and cases of herpes zoster exacerbation were observed in clinical studies with tocilizumab. No cases of Hepatitis B reactivation were observed in the trials; however patients who screened positive for hepatitis were excluded. 5.2 Gastrointestinal Perforations Events of gastrointestinal perforation have been reported in clinical trials, primarily as complications of diverticulitis in patients treated with tocilizumab. Use TOFIDENCE with caution in patients who may be at increased risk for gastrointestinal perforation. Promptly evaluate patients presenting with fever, new onset abdominal symptoms, and a change in bowel habits for early identification of gastrointestinal perforation [see Adverse Reactions (6.1) ]. 5.3 Hepatotoxicity Serious cases of hepatic injury have been observed in patients taking intravenous tocilizumab products. Some of these cases have resulted in liver transplant or death. Time to onset for cases ranged from months to years after treatment initiation with tocilizumab products. While most cases presented with marked elevations of transaminases (> 5 times ULN), some cases presented with signs or symptoms of liver dysfunction and only mildly elevated transaminases. During randomized controlled studies, treatment with tocilizumab was associated with a higher incidence of transaminase elevations [see Adverse Reactions (6.1 , 6.3 , 6.4) ]. Increased frequency and magnitude of these elevations was observed when potentially hepatotoxic drugs (e.g., MTX) were used in combination with tocilizumab. For RA and GCA patients, obtain a liver test panel (serum alanine aminotransferase [ALT], aspartate aminotransferase [AST], alkaline phosphatase, and total bilirubin) before initiating TOFIDENCE, every 4 to 8 weeks after start of therapy for the first 6 months of treatment and every 3 months thereafter. It is not recommended to initiate TOFIDENCE treatment in RA or GCA patients with elevated transaminases ALT or AST greater than 1.5× ULN. In patients who develop elevated ALT or AST greater than 5× ULN, discontinue TOFIDENCE. For recommended modifications based upon increase in transaminases [see Dosage and Administration (2.8) ]. Patients hospitalized with COVID-19 may have elevated ALT or AST levels. Multi-organ failure with involvement of the liver is recognized as a complication of severe COVID-19. The decision to administer TOFIDENCE should balance the potential benefit of treating COVID-19 against the potential risks of acute treatment with TOFIDENCE. It is not recommended to initiate TOFIDENCE treatment in COVID-19 patients with elevated ALT or AST above 10 × ULN. Monitor ALT and AST during treatment. Measure liver tests promptly in patients who report symptoms that may indicate liver injury, such as fatigue, anorexia, right upper abdominal discomfort, dark urine or jaundice. In this clinical context, if the patient is found to have abnormal liver tests (e.g., ALT greater than three times the upper limit of the reference range, serum total bilirubin greater than two times the upper limit of the reference range), TOFIDENCE treatment should be interrupted and investigation done to establish the probable cause.

CONTRAINDICATIONS Tocilizumab-anoh is contraindicated in patients with known hypersensitivity to tocilizumab products [see Warnings and Precautions (5.6) ]. Known hypersensitivity to tocilizumab products. ( 4 )

Mechanism of Action Tocilizumab products bind to both soluble and membrane-bound IL-6 receptors (sIL-6R and mIL-6R), and have been shown to inhibit IL-6-mediated signaling through these receptors. IL-6 is a pleiotropic pro-inflammatory cytokine produced by a variety of cell types including T- and B-cells, lymphocytes, monocytes and fibroblasts. IL-6 has been shown to be involved in diverse physiological processes such as T-cell activation, induction of immunoglobulin secretion, initiation of hepatic acute phase protein synthesis, and stimulation of hematopoietic precursor cell proliferation and differentiation. IL-6 is also produced by synovial and endothelial cells leading to local production of IL-6 in joints affected by inflammatory processes such as rheumatoid arthritis.
