ESMO 2014 Press Release: Rolapitant Reduces Nausea and Vomiting in Phase III Trial

Rolapitant reduces nausea and vomiting in patients receiving cisplatin-based chemotherapy

Lugano/Madrid, 27 September 2014 – Rolapitant reduces nausea and vomiting in patients receiving cisplatin-based chemotherapy, according to the results of a phase III trial presented for the first time today at the ESMO 2014 Congress in Madrid, Spain.

Dr Martin Chasen, lead author and medical director, Palliative Care, Ottawa Hospital Cancer Centre, Canada, said: “This agent makes a significant difference in the way people tolerate their chemotherapy. Patients experienced no loss in quality of life and, in fact, many saw meaningful improvements. One of the patients in the rolapitant cohort reported that he had just finished 18 holes of golf one week after receiving chemotherapy. This is in sharp contrast to many patients on current standard anti-emetics that are too ill to get out of bed within a week after each cycle of cisplatin.”

“We must treat nausea and vomiting, not just the cancer,” added Chasen, emphasising that some patients are extremely sensitive to cisplatin effects and recalling that he had one or two patients with curable cancers who refused treatment after one round of cisplatin. “They preferred to die,” he said.

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. 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).

Chasen said: “Rolapitant demonstrated a significant effect in both the acute and delayed phases. Our primary endpoint was achieved in the delayed phase, an incredible result. We know that the NK-1 receptor in the brain must be blocked to control nausea and vomiting --there are other agents that block this for a short time; rolapitant is an exceptionally long term receptor blocker that binds to the receptor and remains in place for up to 120 hours, therefore not allowing the chemotherapy to induce nausea and vomiting.”

The investigators tested the agent in patients receiving cisplatin, possibly the strongest inducer of emesis.  “Without a doubt this drug can be evaluated in other less emetogenic cancer treatments,” said Chasen.

He pointed out that rolapitant may also save costs. For example, in Ottawa patients can have a visit from a nurse following their chemotherapy who administers intravascular hydration and nutrients. Chasen said: “Patients receiving rolapitant may not require this service. They are able to eat and drink as they should.”
