Head & Neck Cancer and Taxotere®

Locally Advanced Squamous Cell Carcinoma of the Head and Neck1

In 2006, Taxotere® received the first FDA approval for the induction treatment of patients with inoperable locally advanced squamous cell carcinoma of head and neck (SCCHN).2 This indication was updated in 2007 with an expanded label based on the Vermorken, et al study (TAX 324) a multicenter, open-label, randomized, phase III clinical trial comparing Taxotere® + cisplatin + fluorouracil (TPF) vs cisplatin + fluorouracil (PF), followed by concurrent chemoradiotherapy.3

Taxotere® now maintains the following expanded approval by the U.S. Food and Drug Administration (FDA):

Taxotere® in combination with cisplatin and fluorouracil for the induction treatment of patients with locally advanced squamous cell carcinoma of the head and neck.1

Taxotere® sequential therapy (TPF induction followed by concurrent chemoradiotherapy) offers physicians and their patients an important option for treating SCCHN. Taxotere sequential therapy brings together the advances in induction and local therapy. Furthermore, TPF is now one of the induction regimens suggested by the National Comprehensive Cancer Network's guidelines for locally advanced SCCHN.4

Taxotere® Sequential Therapy demonstrated the following benefits vs. PF:2

  • Significantly extended overall survival (OS)—by more than 3 years (P=.0058)
    • 40.5 month improvement in median OS
    • 30% reduction in the risk of mortality (P=.0058)
  • Significantly longer median survival (P=.0058)
    • 70.6 months TPF vs 30.1 months PF (HR 0.70; 95% CI=0.54-0.90)
  • Significantly higher 3-year estimate of OS rate (P=.0058)
    • 62.1% TPF vs 48.1% PF (HR 0.70; 95% CI=0.54-0.90)
    • 29% improvement in OS rate at year 3 (P=.0058)
  • More patients remained on the planned dose and schedule
    • More TPF patients went on to receive CRT: 80.5% TPF vs 75.7% PF
    • No delay or dose reduction in 82.4% of TPF cycles vs 64.4% of PF cycles given
    • Median relative dose intensity:
      • TPF arm: Taxotere® .98; cisplatin .99; fluorouracil .98
      • PF arm: cisplatin .90; fluorouracil .88
  • Fewer patients had surgery following study treatment before or after progressive disease than in the PF arm (25.1% vs 31.7%)
  • Grade 3/4 treatment-emergent adverse events with ≥5% different in the incidence between treatment arms:
    • Less stomatitis, thrombocytopenia, and lethargy in TPF arm
    • More neutropenia and febrile neutropenia (any grade) in the TPF arm
  • Comparable rates of discontinuation due to adverse events (7.5% TPF vs 7.7% PF)
  • Comparable incidence of less common (inferior to 5%) grade 3/4 adverse events between treatment arms
  • Toxic death within 30 days of last study treatment occurred in 1 patient (0.4%) in the TPF arm and in 3 (1.2%) patients in the PF arm
