6.1 Clinical 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 with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Pegfilgrastim clinical trials safety data are based upon 932 patients receiving pegfilgrastim in seven randomized clinical trials.
The population was 21 to 88 years of age and 92% female.
The ethnicity was 75% Caucasian, 18% Hispanic, 5% Black, and 1% Asian.
Patients with breast (n = 823), lung and thoracic tumors (n = 53) and lymphoma (n = 56) received pegfilgrastim after nonmyeloablative cytotoxic chemotherapy.
5 WARNINGS AND PRECAUTIONS • Fatal splenic rupture: Evaluate patients who report left upper abdominal or shoulder pain for an enlarged spleen or splenic rupture.
( 5.1 ) • Acute respiratory distress syndrome (ARDS): Evaluate patients who develop fever, lung infiltrates, or respiratory distress.
Discontinue ZIEXTENZO in patients with ARDS.
( 5.2 ) • Serious hypersensitivity reactions, including anaphylaxis: Permanently discontinue ZIEXTENZO in patients with serious hypersensitivity reactions.
( 5.3 ) • Fatal sickle cell crises: Discontinue ZIEXTENZO if sickle cell crisis occurs.
Like all medications, Ziextenzo can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
