Trial Summary

This trial is to investigate the combination of selumetinib and dexamethasone in the treatment of relapsed/refractory acute lymphoblastic leukaemia (ALL) in both adults and children. The trial is specifically for patients who have an identified change (mutation) in a particular gene in their cancer’s DNA. Phase I is to find the most suitable dose of selumetinib to safely give with dexamethasone. Phase II will use this dose to find out how well the combination works.

Please note that the trials team cannot give individuals clinical advice. Patients and their families should contact their treating physician to discuss trials for which they may be eligible.
