3.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The pooled safety population described in the WARNINGS AND PRECAUTIONS reflects exposure to BIZENGRI as a single agent at 750 mg administered intravenously every 2 weeks until disease progression or unacceptable toxicity in 175 patients with
NRG1 Gene Fusion Positive Unresectable or Metastatic NSCLC
eNRGy Study
The safety of BIZENGRI was evaluated in the eNRGy study in 99 patients with unresectable or metastatic NSCLC with
The median age was 66 years (range: 27 to 88), 54% were 65 years or older; 62% were female; 37% were White, 53% were Asian, 2% were Black or African American; and 1% were Hispanic or Latino.
Serious adverse reactions occurred in 25% of patients who received BIZENGRI. Serious adverse reactions in ≥ 2% of patients included pneumonia (n=4) dyspnea and fatigue (n=2 each). Serious adverse reactions occurring in one patient each were: abdominal pain, acute kidney injury, ascites, bradycardia, carotid artery stenosis, cellulitis, acute cholecystitis, COVID-19, decreased appetite, dehydration, dizziness, dysphagia, hyponatremia, ileus, lymphadenitis, nausea, gastric obstruction, pericardial effusion, pneumonitis, pulmonary hypertension, sepsis, staphylococcal infection, tumor pain, urinary tract infection, viral infection and vomiting. Fatal adverse reactions occurred in 3 (3%) patients and included respiratory failure (n=2) and cardiac failure (n=1).
Permanent discontinuation of BIZENGRI due to an adverse reaction occurred in 3% of patients. Adverse reactions resulting in permanent discontinuation of BIZENGRI included dyspnea, pneumonitis and sepsis (n=1 each).
Dosage interruptions of BIZENGRI due to an adverse reaction, excluding temporary interruptions of BIZENGRI due to infusion-related reactions, occurred in 29% of patients. Adverse reactions leading to dosage interruptions in ≥2% of patients included dyspnea, COVID-19, arrhythmia, increased ALT, increased AST, and pneumonia.
Table 3 summarizes the adverse reactions in the eNRGy study in patients with
Clinically relevant adverse reactions in <10% of patients receiving BIZENGRI were stomatitis (7%), vomiting (8%), cardiac failure and pneumonitis (2% each).
Table 4 summarizes the laboratory abnormalities in the eNRGy study in patients with
NRG1 Gene Fusion Positive Unresectable or Metastatic Pancreatic Adenocarcinoma
eNRGy Study
The safety of BIZENGRI was evaluated in the eNRGy study in 39 patients with unresectable or metastatic pancreatic adenocarcinoma with
The median age was 51 years (range: 21 to 74), 23% were 65 years or older; 49% were female; 82% were White, 13% were Asian, 2.6% were Black or African American; and 5% were Hispanic or Latino.
Serious adverse reactions occurred in 23% of patients who received BIZENGRI. Serious adverse reactions occurring in one patient each were: anemia, thrombocytopenia, tachycardia, abdominal pain, hemorrhoidal hemorrhage, nausea, cholestatic jaundice, COVID-19, liver abscess, traumatic fracture, blood creatinine increased, back pain, myelodysplastic syndrome, and respiratory disorder. There were 2 fatal adverse reactions, one due to COVID-19 and one due to respiratory failure.
Dosage interruptions of BIZENGRI due to an adverse reaction, excluding temporary interruptions of BIZENGRI due to infusion-related reactions, occurred in 33% of patients. Adverse reactions leading to dosage interruptions in ≥2% of patients included COVID-19, pneumonia, increased AST, neutropenia, abdominal pain, agitation, increased blood alkaline phosphatase, increased blood bilirubin, constipation, increased creatinine, hemorrhage, hyperbilirubinemia, cholestatic jaundice, tachycardia, traumatic fracture, and upper respiratory infection.
Table 5 summarizes the adverse reactions in the eNRGy study in patients with
Clinically relevant adverse reactions in <10% of patients receiving BIZENGRI were decreased appetite (5%), and rash (8%) [including dermatitis acneiform, erythema, dermatitis, dermatitis contact, rash maculopapular, rash erythematous].
Table 6 summarizes the laboratory abnormalities in the eNRGy study in patients with
NRG1 Gene Fusion Positive Advanced, Unresectable or Metastatic Cholangiocarcinoma
eNRGy Study
The safety of BIZENGRI was evaluated in the eNRGy study in 22 patients with unresectable or metastatic cholangiocarcinoma with
Serious adverse reactions occurred in 23% of patients who received BIZENGRI. Dosage interruptions of BIZENGRI due to an adverse reaction, excluding temporary interruptions of BIZENGRI due to infusion-related reactions, occurred in 32% of patients. Adverse reactions leading to dosing interruptions or delays in at least 2 patients were increased ALT and increased AST.
