Cyltezo (Subcutaneous)

Patients treated with adalimumab-adbm are at increased risk of infection, some of which may become serious and lead to hospitalization or death. These infections have included TB, invasive fungal infections, bacterial, viral, and those caused by opportunistic pathogens including Legionella and Listeria. The risks and benefits of therapy should be carefully considered prior to treatment initiation in patients with chronic or recurrent infection. Evaluate for latent TB and treat if necessary prior to initiating therapy. Monitor patients closely for signs and symptoms of infection during and after treatment, including the possible development of TB in patients who tested negative prior to treatment. Consider empirical antifungal therapy in at-risk patients who develop severe systemic illness. Lymphoma and other malignancies, some fatal, have been reported in pediatric and adolescent patients treated with tumor necrosis factor (TNF) blockers such as adalimumab-adbm. Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), usually fatal, have been reported in patients treated with TNF blockers including adalimumab-adbm, primarily in adolescent and young adult males with Crohn disease and ulcerative colitis. Most cases occurred in patients receiving concomitant treatment with azathioprine or 6-mercaptopurine .
