Dublin, Ireland-based Jazz Pharmaceuticals will be celebrating news of European approval of its leukaemia drug Vyxeos.

The European Commission is allowing use of the drug to treat adults with newly diagnosed, therapy-related acute myeloid leukaemia (t-AML) or AML with myelodysplasia-related changes (AML-MRC).

Vyxeos is an advanced liposomal formulation that delivers a synergistic molar ratio of daunorubicin and cytarabine, and is “the first chemotherapy to demonstrate an overall survival advantage versus the standard of care in a Phase III study of older adult patients” with these conditions, said Daniel Swisher, Jazz’ president and chief operating officer.

The application included clinical data from five studies, including the pivotal Phase III study, data from which was published in the Journal of Clinical Oncology in July.

The study hits its primary target showing a superior improvement in overall survival compared to an alternative chemotherapy regimen, with 9.6 months versus 5.9 months, respectively.

“AML is a rare cancer in Europe and patients with therapy-related AML or AML with myelodysplasia-related changes have a particularly poor prognosis compared to people with other forms of leukaemia,” said Professor Charles Craddock CBE, academic director, Centre for Clinical Haematology at University Hospitals Birmingham NHS Foundation Trust.

“Vyxeos is a new and clinically meaningful treatment option that provides a welcome advance for patients and health care professionals across the European Union.”
