Dasatinib (Sprycel) - adult acute lymphocytic leukemia (Ph(+) ALL)

1. Can anyone provide information about the experiences of adult acute lymphocytic leukemia (Ph(+) ALL) patients who stopped taking Dasatinib (Sprycel) after going into remission  and completing consolidation therapy? A stem cell transplantation was not and will not be performed.

2. What information and/or research is there on continuing on Dasatinib (Sprycel) after Philadelphia chromosome positive adult acute lymphocytic leukemia (Ph(+) ALL) patients go into remission and complete consolidation therapy to help keep the leukemia from coming back? A stem cell transplantation was not and will not be performed.

Thank you
