Clinical evidence The clinical effectiveness evidence is relevant to NHS clinical practice in England. The evidence for liposomal cytarabine– daunorubicin came from Study 301. This was a Phase III, multicentre, open-label, randomised trial. It included 309 adults aged 60 to 75 years with high-risk acute myeloid leukaemia. High-risk acute myeloid leukaemia was defined as therapy-related acute myeloid leukaemia, acute myeloid leukaemia with myelodysplastic syndrome, de novo acute myeloid leukaemia with myelodysplastic syndrome-associated karyotypic changes and chronic myelomonocytic leukaemia. The trial compared liposomal cytarabine– daunorubicin (n=153) with standard cytarabine and daunorubicin chemotherapy (n=156), in a 3+7 schedule (3 days of cytarabine then 7 days of daunorubicin). The clinical experts confirmed that it was reasonable to assume equivalence between the 3+7 schedule in the trial and the 3+10 schedule normally used in the UK. They also confirmed that, although the trial was done in the US and Canada, the baseline characteristics of people in the trial were representative of people in the UK who would be eligible for liposomal cytarabine– daunorubicin. The clinical experts explained that about a quarter of patients who would be eligible for treatment in England would be under 60 years. There was no biological reason to expect treatment benefit to be any different to that seen in people aged Clinical management Current treatment is chemotherapy. Current treatment for therapy-related acute myeloid leukaemia and acute myeloid leukaemia with myelodysplasia- related changes is intensive chemotherapy, for people who are well enough to have it. This usually involves a first induction course, and two or three further courses of standard daunorubicin and cytarabine to treat any remaining cancer cells (consolidation therapy). In the NHS, the first induction course is usually given as 3 days of daunorubicin and 10 days of cytarabine (known as DA 3+10). The clinical experts highlighted that some younger patients may have FLAG-Ida (fludarabine, cytarabine, granulocyte-colony stimulating factor and idarubicin) chemotherapy instead. The committee understood that liposomal cytarabine– daunorubicin is a liposomal formulation of standard cytarabine and daunorubicin chemotherapy. This could be used as an alternative in clinical practice. The committee was aware that diagnosing some types of high- risk acute myeloid leukaemia, particularly de novo acute myeloid leukaemia with myelodysplastic syndrome- associated karyotypic changes, involves genetic testing. In England, genetic test results may not be available for 7 to 10 days. The clinical experts advised that it is becoming more common for clinicians to wait for these test results before starting treatment. A small number of patients with more aggressive disease would need to start treatment sooner. The committee agreed that no change in practice would be needed for most people who would be eligible for liposomal cytarabine– daunorubicin, if it were to recommend
