A trial looking at AT9283 for children and young people with acute leukaemia
This trial was for children and young people whose acute leukaemia had stopped responding to treatment or had come back. This trial was supported by Cancer Research UK.
More about this trial
Doctors treat acute myeloid leukaemia and acute lymphoblastic leukaemia with treatments such as chemotherapy. But sometimes the treatment stops working or the leukaemia comes back later on. Doctors are looking for new treatments to help people in this situation. In this trial, they looked at a drug called AT9283.
AT9283 stops a protein called aurora kinase from working. Aurora kinase is important for cells to divide and grow. Doctors hoped that stopping aurora kinase from working would help to treat acute leukaemia.
The aims of the trial were to
- Find the best dose of AT9283
- Find out what happens to AT9283 in the body
- Learn more about the side effects of AT9283
- See if AT9283 helped children and young people with acute leukaemia
Summary of results
The trial team were unable to find the best dose of AT9283 because of the low numbers of children who took part. As a result the trial closed early.
The first few patients taking part had a low dose of AT9283. The next few patients had a higher dose and so on. This is called a dose escalation study.
This trial looked at 3 different doses of AT9283, a low, medium and higher dose.
- 3 children had a low dose of AT9283
- 3 children had the medium dose of AT9283
- 1 child had the higher dose of AT9283
All 7 children were withdrawn from the trial during or at the end of their first cycle of treatment because their leukaemia had started to grow again. So they did not have any further treatment with AT9283.
The most common side effect reported were
1 of the patients died during the trial. The doctors concluded that this was due to their leukaemia and not related to treatment with AT9283.
The trial team was not able to recommend a dose of AT9283 that could be used in future trials. It was not possible to find out whether AT9283 was useful for acute leukaemia because
- not enough patients took part.
- those who took part only had 1 cycle of treatment before their leukaemia started to grow again
