Trial Summary

Mini Allo Glivec is a phase I/II, single arm, multicentre study of a targeted drug called ‘Imatinib’ in patients undergoing reduced intensity allogeneic stem cell transplantation (or a ‘mini transplant’ for chronic myeloid leukaemia (CML) in 1st chronic phase. The main objectives of the trial were to assess the safety and tolerability of receiving Imatinib after undergoing a ‘mini transplant’ and to investigate the ‘anti-leukaemic activity’ of a ‘mini transplant’ when given with adjunctive targeted therapy in the form of Imatinib.

The trial looked at the results of 21 of the 22 people recruited to this trial and the study showed that giving targeted therapy after a ‘mini’ transplant increased the amount of time before CML came back. It also showed that there was a low risk of side effects with this combination of treatment.

After undergoing a ‘mini transplant’ all patients took Imatinib therapy for 1 year. Tests after finishing Imatinib showed that 7 patients had no sign of CML. The most common side effect of imatinib was feeling or being sick.

Of the 21 people, 15 had CML come back after their transplant. The average amount of time it took to come back was 17 months. After more treatment 10 of the 15 had no sign of CML.

After the transplant only 1 person had Graft Versus Host Disease (GVHD) as a complication. After further treatment when CML came back, 2 people had GVHD.

Out of the 21 people 19 were alive at least 3 years after treatment.

The researchers concluded that this combination of treatment worked well for people having a mini transplant. And there was a low risk of side effects or complications.

Please note that the trials team cannot give individual’s clinical advice.
