  Randomized Controlled Trial

  Efficacy and safety of every-2-week darbepoetin alfa in patients with anemia of cancer: a controlled, randomized, open-label phase II trial.

  This randomized, controlled trial evaluated the effect of darbepoetin alfa on hospitalization days, transfusion requirements, hemoglobin levels, and fatigue in patients with anemia of cancer (AOC). Eligible patients were anemic (hemoglobin or=18 years old, and had not received chemotherapy or radiotherapy within 4 weeks of study screening. Patients were randomized 4:1 to receive darbepoetin alfa, 3.0 microg/kg every 2 weeks (Q2W) (n = 226), or observation only for 12 weeks (n = 59), followed by an optional 9 weeks of darbepoetin alfa, 3.0 microg/kg Q2W. ⋯ By week 13, hemoglobin increased by 2.1 g/dl in patients receiving darbepoetin alfa, compared with 0.1 g/dl in the observation group p < .0001. Hemoglobin improvements were paralleled by an increase in Functional Assessment of Cancer Therapy-Fatigue score (mean change in score at week 13: darbepoetin alfa, 6.0; observation, 2.2; p < .05). Darbepoetin alfa Q2W can significantly improve hemoglobin levels and reduce transfusion requirements in patients with AOC, resulting in significant improvements in health-related quality of life.

  FDA drug approval summary: bevacizumab (Avastin) plus Carboplatin and Paclitaxel as first-line treatment of advanced/metastatic recurrent nonsquamous non-small cell lung cancer.

  On October 11, 2006, the U. S. Food and Drug Administration granted approval for bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA), administered in combination with carboplatin and paclitaxel, for the initial treatment of patients with unresectable, locally advanced, recurrent, or metastatic, nonsquamous, non-small cell lung cancer (NSCLC). ⋯ Fatal, treatment-related adverse events in patients receiving bevacizumab were pulmonary hemorrhage (2.3% versus 0.5%), gastrointestinal hemorrhage, central nervous system infarction, gastrointestinal perforation, myocardial infarction, and neutropenic sepsis. The most serious, and sometimes fatal, bevacizumab toxicities are gastrointestinal perforation, wound healing complications, hemorrhage, arterial thromboembolic events, hypertensive crisis, nephrotic syndrome, congestive heart failure, and neutropenic sepsis. The most common adverse events in patients receiving bevacizumab are asthenia, pain, abdominal pain, headache, hypertension, diarrhea, nausea, vomiting, anorexia, stomatitis, constipation, upper respiratory infection, epistaxis, dyspnea, exfoliative dermatitis, and proteinuria.
