Safety and Antiemetic Efficacy of Akynzeo Plus Dexamethasone During Radiotherapy and Concomitant Weekly Cisplatin

Brief description of study

This is a multicentre, single-arm, phase II study to investigate the safety and antiemetic efficacy of Akynzeo (a fixed dose combination of palonosetron and netupitant) plus dexamethasone in patients receiving concomitant chemo-radiotherapy with weekly cisplatin for at least five weeks.

Detailed Study Description

Akynzeo contains a combination of the neurokinin-1 receptor antagonist netupitant and the serotonin receptor antagonist palonosetron. Akynzeo is approved as antiemetic prophylaxis in patients receiving high emetogenic chemotherapy e.g. high dose cisplatin administered every three weeks.

From a previous clinical trial (GAND-emesis trial) we know that patients receiving radiotherapy and concomitant weekly cisplatin 40 mg/m2 are better protected against nausea and vomiting when a triplet antiemetic prophylaxis (neurokinin-1 receptor antagonist, serotonin receptor antagonist, and corticosteroid) is applied.

In the Akynzeo phase III clinical trials, Akynzeo was administered every three weeks. The neurokinin-1 receptor antagonist, netupitant, has a long plasma half-life (approx. 90 hours), and theoretically the drug could accumulate when administered on a weekly basis.

The DANGER-emesis trial is designed to collect safety and efficacy data in patients receiving Akynzeo weekly as antiemetic prophylaxis in combination with dexamethasone in patients treated for cervical cancer with radiotherapy and concomitant weekly cisplatin 40 mg/m2.
