No dose reduction or escalation for IMFINZI is recommended. In general, withhold IMFINZI for severe (Grade 3) immune-mediated adverse reactions. Permanently discontinue IMFINZI for life-threatening (Grade 4) immune-mediated adverse reactions, recurrent severe (Grade 3) immune-mediated reactions that require systemic immunosuppressive treatment, or an inability to reduce corticosteroid dose to 10 mg or less of prednisone or equivalent per day within 12 weeks of initiating corticosteroids.
Immune-mediated adverse reactions requiring specific management are summarized in Table 10. Refer to Precautions for further monitoring and evaluation information. (See Table 10.)

For suspected immune-mediated adverse reactions, adequate evaluation should be performed to confirm etiology or exclude alternate etiologies.
For non-immune-mediated adverse reactions, withhold IMFINZI for Grade 2 and 3 adverse reactions until ≤ Grade 1 or baseline. IMFINZI should be discontinued for Grade 4 adverse reactions (with the exception of Grade 4 laboratory abnormalities, about which the decision to discontinue should be based on accompanying clinical signs/symptoms and clinical judgment).
Special patient populations: Based on a population pharmacokinetic analysis, no dose adjustment of IMFINZI is recommended based on patient age, body weight, gender and race (see Pharmacology: Pharmacokinetics under Actions).
Paediatric and adolescents: The safety and effectiveness of IMFINZI have not been established in children and adolescents aged less than 18 years.
Elderly (≥ 65 years): No dose adjustment is required for elderly patients (≥ 65 years of age) (see Pharmacology: Pharmacodynamics and Pharmacokinetics under Actions).
Renal impairment: No dose adjustment of IMFINZI is recommended in patients with mild or moderate renal impairment. Data from patients with severe renal impairment are too limited to draw conclusions on this population (see Pharmacology: Pharmacokinetics under Actions).
Hepatic impairment: Based on a population pharmacokinetic analysis, no dose adjustment of IMFINZI is recommended for patients with mild or moderate hepatic impairment. IMFINZI has not been studied in patients with severe hepatic impairment (see Pharmacology: Pharmacokinetics under Actions).
Method of administration: For intravenous administration.
