Smart drug improves survival in older patients with acute myeloid leukemia

13.11.2012
A new study has found Acute Myeloid Leukaemia (AML) patients given a new type of 'smart drug' in addition to chemotherapy treatment are 22 per cent less likely to relapse and around 13 per cent less likely to die from their disease. The results are from a major phase III Cancer Research UK-funded trial led by Cardiff University.

Of the 1,115 patients who took part in the trial, 68 per cent relapsed on the new treatment within three years, compared with 76 per cent of those who had the standard treatment. And 25 per cent were still alive after three years, compared with 20 per cent of those who had the standard treatment.

The drug – called Gemtuzumab Ozogamicin (GO) – is part of a new class of 'antibody conjugate' drugs, which involve attaching chemotherapy molecules to antibodies specifically designed to recognise proteins on the surface of cancer cells, thereby targeting the cancer while leaving healthy cells unharmed.

The results of the trial show that adding GO to treatment could improve the effectiveness of chemotherapy without excessively increasing side effects, providing a potential lifeline for older AML patients who are often too frail to tolerate more intensive chemotherapy regimes.

The results are published in the Journal of Clinical Oncology.

Chief investigator Professor Alan Burnett, School of Medicine, said: "These promising results demonstrate how targeting a protein present in more than 90 per cent of AML patients can boost treatment without excessively increasing side effects.

"Although there has been some controversy around the use of GO following its withdrawal in the US two years ago, these results appear extremely promising and suggest no such cause for concern if the appropriate dose is given. Crucially, this represents some of the first progress in treating AML patients of this age group for at least 20 years."

Trial participants were recruited at 149 hospitals around the UK and Denmark. All patients had been recently diagnosed with either AML or high risk myelodysplastic syndrome, which can develop into AML, and the majority were aged over 60. Each patient was randomly assigned to receive one of two standard chemotherapy regimes, either with or without GO.

Kate Law, Cancer Research UK's director of clinical research, said: "In general the outlook for leukaemia patients has improved dramatically in recent decades. But when leukaemia is diagnosed in older people it's much harder to treat and there is a real need for effective treatments that are suitable for this age group.

"Importantly this new trial shows that GO may have particular benefits for patients over 60, who may be unsuitable for other more intensive treatments. This is good news and we are now looking to see if these results can be replicated in younger patients."

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
