6 ADVERSE REACTIONS 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.

( 6.1 ) • The most common adverse reactions (≥ 20%) in NSCLC are anemia, neutropenia, thrombocytopenia, alopecia, peripheral neuropathy, nausea, and fatigue. ( 6.1 ) • The most common (≥ 20%) adverse reactions of Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) in adenocarcinoma of the pancreas are neutropenia, fatigue, peripheral neuropathy, nausea, alopecia, peripheral edema, diarrhea, pyrexia, vomiting, decreased appetite, rash, and dehydration.

Table 6: Adverse Reactions in the Randomized Metastatic Breast Cancer Study on an Every-3-Weeks Schedule a Paclitaxel injection patients received premedication. b Includes treatment-related events related to hypersensitivity (e.g., flushing, dyspnea, chest pain, hypotension) that began on a day of dosing. c Severe events are defined as at least Grade 3 toxicity.

Among patients with metastatic breast cancer in the randomized trial, neutrophil counts declined below 500 cells/mm 3 (Grade 4) in 9% of the patients treated with a dose of 260 mg/m 2 compared to 22% in patients receiving paclitaxel injection at a dose of 175 mg/m 2 . Pancytopenia has been observed in clinical trials. Infections Infectious episodes were reported in 24% of the patients treated with Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound). Oral candidiasis, respiratory tract infections and pneumonia were the most frequently reported infectious complications. Hypersensitivity Reactions (HSRs) Grade 1 or 2 HSRs occurred on the day of Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) administration and consisted of dyspnea (1%) and flushing, hypotension, chest pain, and arrhythmia (all <1%). The use of Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) in patients previously exhibiting hypersensitivity to paclitaxel injection or human albumin has not been studied. Cardiovascular Hypotension, during the 30-minute infusion, occurred in 5% of patients. Bradycardia, during the 30-minute infusion, occurred in <1% of patients. These vital sign changes most often caused no symptoms and required neither specific therapy nor treatment discontinuation. Severe cardiovascular events possibly related to single-agent Paclitaxel Protein-Bound Particles for Injectable Suspension (Albumin-Bound) occurred in approximately 3% of patients. These events included cardiac ischemia/infarction, chest pain, cardiac arrest, supraventricular tach
