There are no contraindications for IMFINZI™ (durvalumab).
Monitor patients for clinical signs and symptoms of immune-mediated pneumonitis, hepatitis, colitis or diarrhea, endocrinopathies, nephritis, rash or dermatitis, other immune-mediated adverse reactions, and infection. Please refer to the full Prescribing Information for important dose management information specific to adverse reactions.
In the combined safety database (n=1414), immune-mediated pneumonitis occurred in 32 patients (2.3%), including 1 fatal case (0.1%) and 6 Grade 3–4 cases (0.4%). In Study 1 (n=182), 1 patient (0.5%) died from immune-mediated pneumonitis. Monitor patients for signs and symptoms of pneumonitis and evaluate with radiographic imaging when suspected. Administer corticosteroids for ≥Grade 2 pneumonitis. Withhold IMFINZI for Grade 2 pneumonitis; permanently discontinue for Grade 3–4 pneumonitis.
In the combined safety database (n=1414), immune-mediated hepatitis occurred in 16 patients (1.1%), including 1 fatal case (<0.1%) and 9 Grade 3 cases (0.6%). Grade 3–4 elevations in ALT occurred in 40/1342 patients (3.0%), AST in 58/1336 patients (4.3%), and total bilirubin in 37/1341 patients (2.8%). In Study 1 (n=182), 1 patient (0.5%) died from immune-mediated hepatitis, and 2 patients (1.1%) experienced immune-mediated hepatitis, including 1 Grade 3 case (0.5%). Monitor patients for abnormal liver tests in each cycle during treatment with IMFINZI. Administer corticosteroids and withhold IMFINZI for Grade 2–3 ALT or AST >3–5X ULN or ≤8X ULN or total bilirubin >1.5–3X ULN or ≤5X ULN. Permanently discontinue IMFINZI in patients with Grade 3 ALT or AST >8X ULN or total bilirubin >5X ULN, or in patients with concurrent ALT or AST >3X ULN and total bilirubin >2X ULN with no other cause.
In the combined safety database (n=1414), immune-mediated colitis or diarrhea occurred in 18 patients (1.3%), including 1 Grade 4 case (<0.1%) and 4 Grade 3 cases (0.3%). In Study 1 (n=182), 23 patients (12.6%) experienced colitis or diarrhea, including 2 Grade 3–4 cases (1.1%). Monitor patients for signs and symptoms of colitis or diarrhea. Administer corticosteroids for ≥Grade 2 colitis or diarrhea. Withhold IMFINZI for Grade 2 colitis or diarrhea; permanently discontinue for Grade 3–4 colitis or diarrhea.
Other immune-Mediated Adverse Reactions
Severe infections, including sepsis, necrotizing fasciitis, and osteomyelitis, occurred in patients receiving IMFINZI. In the combined safety database (n=1414), infections occurred in 531 patients (37.6%). In Study 1 (n=182), infections occurred in 54 patients (29.7%). 11 patients (6.0%) experienced Grade 3–4 infection and 5 patients (2.7%) were experiencing infection at the time of death. 8 patients (4.4%) experienced urinary tract infection, the most common ≥Grade 3 infection. Monitor patients for signs
and symptoms of infection and treat with anti-infectives for suspected or confirmed infections. Withhold IMFINZI for ≥Grade 3 infection.
In the combined safety database (n=1414), severe infusion-related reactions occurred in 26 patients (1.8%). In Study 1 (n=182), infusion-related reactions occurred in 3 patients (1.6%). There were 5 Grade 3 (0.4%) and no Grade 4 or 5 reactions. Patients should be monitored for signs and symptoms of infusion-related reactions. Interrupt or slow the rate of infusion for Grade 1–2 infusion-related reactions and permanently discontinue for Grade 3–4 infusion-related reactions.
Based on its mechanism of action and data from animal studies, IMFINZI can cause fetal harm when administered to a pregnant woman. There are no data on the use of IMFINZI in pregnant women. Advise pregnant women of the potential risk to a fetus and advise women of reproductive potential to use effective contraception during treatment and for at least 3 months after the last dose of IMFINZI.
There is no information regarding the presence of IMFINZI in human milk; however, because of the potential for adverse reactions in breastfed infants from IMFINZI, advise a lactating woman not to breastfeed during treatment and for at least 3 months after the last dose.
Most Common Adverse Reactions
The safety and effectiveness of IMFINZI have not been established in pediatric patients.
IMFINZI is indicated for the treatment of patients with locally advanced or metastatic urothelial carcinoma who:
- have disease progression during or following platinum-containing chemotherapy
- have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy
This indication is approved under accelerated approval based on tumor response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.
