†The NIAGARA Regimen is defined as neoadjuvant IMFINZI + gem-cis followed by adjuvant IMFINZI as a single agent after RC.

‡Includes multiple similar terms.

§Includes eczema, erythema, rash, rash erythematous, rash maculo-papular, rash papular, rash pruritic, and rash pustular.

‖Includes asthenia and fatigue.

Includes blood thyroid stimulating hormone increased and hypothyroidism.

  • For patients treated with IMFINZI + gem-cis in the neoadjuvant phase (n=530)1:
    • Serious ARs were reported in 24% of patients. The most frequent serious ARs (≥1%) were pulmonary embolism (1.9%), febrile neutropenia (1.5%), acute kidney injury, thrombocytopenia, urinary tract infection, and pneumonia (1.3% each)
    • No fatal ARs occurred
    • Fatal ARs occurred in 1.1% of patients, including sepsis, myocardial infarction, and pulmonary embolism (0.2% each). One fatal AR of pneumonia (0.2%) was reported in the post-RC phase prior to adjuvant treatment
  • For patients treated with IMFINZI in the adjuvant phase (n=383)1:
    • Serious ARs were reported in 26% of patients. The most frequent serious ARs (≥1%) were urinary tract infection (7%), acute kidney injury (3.7%), hydronephrosis (2.1%), pyelonephritis (2.1%), urosepsis (1.8%), and sepsis (1.6%)
    • No fatal ARs occurred
    • Fatal ARs occurred in 1.8% of patients, including COVID-19, severe acute respiratory syndrome, cardiopulmonary failure, gastrointestinal hemorrhage, and chronic hepatic failure (0.3% each)

Low rates of treatment discontinuation due to ARs observed in each phase1

Discontinuation of Neoadjuvant IMFINZI1*

9%

of patients permanently discontinued neoadjuvant IMFINZI due to ARs

  • The most frequent ARs (≥0.5%) leading to permanent discontinuation of neoadjuvant IMFINZI were increased blood creatinine (0.9%), neutropenia, acute kidney injury, asthenia, and fatigue (0.6% each)1

Discontinuation of adjuvant IMFINZI1†

5%

of patients permanently discontinued adjuvant IMFINZI due to ARs

  • The most frequent ARs (≥0.5%) leading to permanent discontinuation of adjuvant IMFINZI were nephritis (0.8%), fatigue, diarrhea, decreased appetite, and pneumonitis (0.5% each)1

*A total of 530 patients received at least 1 dose of IMFINZI in combination with gem-cis as neoadjuvant treatment in the IMFINZI treatment arm.1

†383 patients in the IMFINZI treatment arm received at least 1 dose of adjuvant treatment.1

†The NIAGARA Regimen is defined as neoadjuvant IMFINZI + gem-cis followed by adjuvant IMFINZI as a single agent after RC.1

‡Each test incidence is based on the number of patients who had both baseline and at least 1 on-study laboratory measurement available: The NIAGARA Regimen† (range: 482-528) and neoadjuvant gem-cis (range: 467-521).

  • No overall differences in safety or effectiveness for the NIAGARA Regimen† have been observed between patients ≥65 years of age and younger adult patients1§

§Of the 530 patients treated with IMFINZI + gem-cis, 272 patients (51%) were 65 years or older, and 57 patients (11%) were 75 years or older.1
