For that reason, patients receiving chemotherapy regimens based on an anthracycline and cyclophosphamide were included in a separate phase 3 study14 assessing safety and efficacy of rolapitant in patients with cancer treated with moderately emetogenic chemotherapy. The findings of HEC-1 and HEC-2 support those of that separate phase 3 study. Collectively, these three studies show that oral rolapitant (180 mg dose) taken once
before chemo therapy, in combination with a 5HT3 receptor antagonist and corticosteroid, is superior to a 5-HT3 receptor antagonist and cortico steroid alone in providing protection against chemotherapy-induced nausea and vomiting for the entire at-risk period in patients receiving moderately or highly emetogenic chemotherapy
