European Commission approves ALOXI injection to prevent nausea and vomiting due to chemotherapy in children as young as one month

Helsinn Group has announced that the European Commission has approved ALOXI® (palonosetron HCl) injection for the prevention of acute chemotherapy-induced nausea and vomiting (CINV) in children aged one to six months.

This is the first European approval of a product for the prevention of acute CINV in children aged one to six months. Since the childhood cancer incidence tends to be higher within the first 3 years of life this approval offers an important therapeutic option to children and especially young infants undergoing cancer chemotherapy.

Helsinn has conducted four paediatric clinical trials with ALOXI

CINV is among the most common side effects following therapy in patients with cancer. In clinical trials in paediatric patients, CINV frequency varied from 35 to 80% depending on the age of the patient the site of tumour and the type of chemotherapy given. Helsinn has conducted four paediatric clinical trials with ALOXI.

The approval of the paediatric indication is based on a randomized double-blind non-inferiority pivotal trial comparing single-dose intravenous (IV) ALOXI 20 mcg/kg given 30 minutes prior to chemotherapy to a standard of care IV ondansetron regimen of 0.15 mg/kg given 30 minutes prior to chemotherapy followed by ondansetron infusions four and eight hours after the first dose. Within the first 24 hours after chemotherapy Complete Response defined as no vomiting no retching and no antiemetic rescue medication was achieved in 59.4% of patients who received ALOXI 20 mcg/kg and in 58.6% of those who received the ondansetron regimen. Therefore the study met its primary endpoint.

Treatment-emergent adverse events were comparable across both treatments with headache being the most frequent event in the palonosetron group.

Riccardo Braglia, CEO of Helsinn Group, said, “The European Commission’s approval of ALOXI injection for the prevention of acute nausea and vomiting in children aged one month or more is an important validation of Helsinn’s position as a world-leading company in cancer supportive care and of its development expertise. This approval will give another treatment option for physicians when treating childhood cancer in particular for the fragile infancy group.”
