To measure expression and function of Bcl-2 family proteins and its modulation by venetoclax in ALL blasts. The change in expression of BCL-2 family proteins from baseline to the time of each response assessment will be measured including BCL-2 and summary statistics including the median and interquartile range of the change will be reported for all patients in the expansion cohort and also summarized for those achieving a CR/CRi and those patients who do not achieve a CR/CRi. This is based on section 9.1: We plan to collect bone marrow and peripheral blood samples at baseline, at the time of clinical response assessment and at the time of progression for correlative studies. These will be done in the laboratory of Dr. Marina Konopleva at MDACC and Dr. Tony Letai at DFCI.
