Key finding

Dronabinol was significantly inferior to megestrol acetate in the treatment of tumor-related anorexia; the combination provided no additional benefit.

Summary

n=469 patients with advanced cancer and anorexia, randomized to megestrol acetate 800 mg/d vs. dronabinol 2,5 mg 2×daily vs. combination. Megestrol acetate superior to dronabinol: appetite improvement 75% vs. 49% (p=0,0001), ≥10% weight gain 11% vs. 3% (p=0,02). Combination therapy without additional benefit over megestrol acetate monotherapy.
