Abstract Text On November 7, 2011, the U.S. Food and Drug Administration approved cetuximab in combination with cisplatin or carboplatin and 5-fluorouracil for the first-line treatment of patients with recurrent locoregional or metastatic squamous cell head and neck cancer. Approval was based on a randomized study of 442 patients conducted outside the U.S. Cisplatin (100 mg/m2 intravenously) or carboplatin (area under the curve 5 intravenously) on day 1 with 5-fluorouracil (1,000 mg/m2/day continuous intravenous infusion days 1-4) were administered every 3 weeks. Cetuximab, 400 mg/m2 intravenously, was administered initially followed by cetuximab, 250 mg/m2 intravenously weekly. After completion of six planned treatment courses, cetuximab patients without progression continued cetuximab 250 mg/m2 weekly. The study used European Union (EU)-approved cetuximab rather than U.S.-approved cetuximab. U.S.-approved cetuximab provides approximately 28% higher exposure relative to EU-approved cetuximab in a pharmacokinetic comparability study in monkeys. Overall survival, the primary efficacy endpoint, was significantly improved in cetuximab-treated patients (hazard ratio [HR]: 0.80; 95% confidence interval [CI]: 0.64-0.98; p = .034, stratified log-rank test). Median survival times were 10.1 and 7.4 months, respectively. Progression-free survival (PFS) was also significantly improved in patients receiving cetuximab (HR: 0.57; 95% CI: 0.46-0.72; p < .0001). Median PFS times were 5.5 and 3.3 months, respectively. Response rates were 35.6% and 19.5% (odds ratio: 2.33; 95% CI: 1.50-3.60; p = .0001). Adverse reactions (≥25%) from cetuximab plus chemotherapy treatment included nausea, anemia, vomiting, neutropenia, rash, asthenia, diarrhea, and anorexia. Conjunctivitis occurred in 10% of cetuximab patients. Other adverse reactions, sometimes severe, included infusion reactions, hypomagnesemia, hypocalcemia, and hypokalemia.

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.
