Detailed Description:

OBJECTIVES:

  • Determine whether the addition of powdered shark cartilage (BeneFin™) to standard therapy improves overall survival in patients with advanced colorectal or breast cancer.
  • Determine whether this therapy has any impact on toxicity in these patients.
  • Determine whether this therapy improves the quality of life in these patients.

OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to disease type (breast vs colorectal female vs colorectal male), age (49 and under vs 50-69 vs 70 and over), ECOG performance status (0-1 vs 2), baseline quality of life (UNISCALE rating less than 50% vs 50-75% vs more than 75%), and concurrent chemotherapy (yes vs no). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive oral shark cartilage (BeneFin™) 3-4 times daily.
  • Arm II: Patients receive oral placebo 3-4 times daily. Treatment continues in the absence of unacceptable toxicity.

Quality of life is assessed weekly for 1 month and then monthly thereafter during treatment.

Patients are followed every 6 months for 5 years.

PROJECTED ACCRUAL: A total of 600 patients (300 per treatment arm) will be accrued for this study within 24 months.
