According to results presented at the ESMO 2014 Congress in Madrid, Rolapitant reduces nausea and vomiting in patients receiving cisplatin-based chemotherapy. The phase III trial investigated rolapitant, a novel antagonist of the NK-1 receptor, for the prevention of severe nausea and vomiting often experienced by patients receiving cisplatin-based chemotherapy, which may cause dose reductions and treatment discontinuation. Cisplatin is possibly the strongest inducer of emesis.
The multicentre trial randomised 532 patients 1:1 to receive rolapitant plus granisetron/dexamethasone or placebo plus granisetron/dexamethasone prior to cisplatin-based chemotherapy.
The primary endpoint was complete response (defined as the patient having no emesis and not requiring any rescue medication) in the delayed phase (>24-120 hours) post-chemotherapy. Key secondary endpoints included complete response during the acute (0-24 hours) and overall (0-120 hours) phases.
The trial met its primary endpoint, with 72.7% of patients receiving rolapitant achieving complete response in the delayed phase compared to 58.4% of those receiving placebo (p<0.001). Rolapitant also improved the complete response rate compared to placebo in the acute (83.7% vs 73.7%, p=0.005) and overall (70.1% vs 56.5%, p=0.001) phases. Patients receiving rolapitant tended to report that chemotherapy had less of an impact on their daily quality of life (72.8% vs 67.8%, p=0.231).
