for ≥Grade 3 pulmonary hemorrhage for placebo plus docetaxel. For patients with squamous histology, the overall incidence of pulmonary hemorrhage was 10% and the incidence of ≥Grade 3 pulmonary hemorrhage was 2% for CYRAMZA plus docetaxel compared to 12% overall incidence and 2% for ≥Grade 3 pulmonary hemorrhage for placebo plus docetaxel.
The most common serious adverse events with CYRAMZA plus docetaxel were febrile neutropenia (14%), pneumonia (6%), and neutropenia (5%). The use of granulocyte colony-stimulating factors was 42% in CYRAMZA plus docetaxel-treated patients versus 37% in patients who received placebo plus docetaxel. In patients ≥65 years, there were 18 (8%) deaths on treatment or within 30 days of discontinuation for CYRAMZA plus docetaxel and 9 (4%) deaths for placebo plus docetaxel. In patients <65 years, there were 13 (3%) deaths on treatment or within 30 days of discontinuation for CYRAMZA plus docetaxel and 26 (6%) deaths for placebo plus docetaxel.
Table 4 provides the frequency and severity of adverse reactions in Study 3.
Table 4: Adverse Reactions Occurring at Incidence Rate ≥5% and a ≥2% Difference Between Arms in Patients Receiving CYRAMZA in Study 3
Clinically relevant adverse drug reactions reported in ≥1% and <5% of the CYRAMZA plus docetaxel-treated patients in Study 3 were hyponatremia (4.8% CYRAMZA plus docetaxel versus 2.4% for placebo plus docetaxel) and proteinuria (3.3% CYRAMZA plus docetaxel versus 0.8% placebo plus docetaxel).
Colorectal Cancer
CYRAMZA Administered in Combination with FOLFIRI
Study 4 was a multinational, randomized, double-blind study conducted in patients with metastatic colorectal cancer with disease progression on or after therapy with bevacizumab, oxaliplatin, and a fluoropyrimidine. Patients received either CYRAMZA 8 mg/kg intravenously plus FOLFIRI intravenously every 2 weeks or placebo plus FOLFIRI intravenously every 2 weeks.
Study 4 excluded patients with an ECOG PS of 2 or greater, uncontrolled hypertension, major surgery within 28 days, and those who experienced any of the following during first-line therapy with a bevacizumab-containing regimen: an arterial thrombotic/thromboembolic event; Grade 4 hypertension; Grade 3 proteinuria; a Grade 3-4 bleeding event; or bowel perforation.
Demographics and baseline characteristics for the treated population were similar between treatment arms (n=1057). Median age was 62 years; 57% of patients were men; 76% were White and 20% were Asian; 48% had ECOG PS 0.
The data described in this section reflect exposure to CYRAMZA plus FOLFIRI in 529 patients in Study 4. Patients received a median of 8 doses (range 1-68) of CYRAMZA; the median duration of exposure was 4.4 months, and 169 (32% of 529) patients received CYRAMZA for at least six months. The most common adverse reactions (all grades) observed in CYRAMZA plus FOLFIRI-treated patients at a rate of ≥30% and ≥2% higher than placebo plus FOLFIRI were diarrhea, neutropenia, decreased appetite, epistaxis, and stomatitis. Twenty percent of patients treated with CYRAMZA plus FOLFIRI received granulocyte colony-stimulating factors. Treatment discontinuation of any study drug due to adverse reactions occurred more frequently in CYRAMZA plus FOLFIRI-treated patients (29%) than in placebo plus FOLFIRI-treated patients (13%).
