Study Summary
This phase I/Ib trial tests the safety and side effects of asparaginase Erwinia chrysanthemi-recombinant-rywn (recombinant Erwinia asparaginase) and venetoclax in combination with blinatumomab and how well the combination works in treating patients with CD19 positive B-cell acute lymphoblastic leukemia (ALL) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Asparaginase Erwinia chrysanthemi, a type of protein synthesis inhibitor, is a drug that is made up of the enzyme asparaginase, which comes from the bacterium Erwinia chrysanthemi. It is used in people who cannot take asparaginase that comes from the bacterium E. coli. Asparaginase Erwinia chrysanthemi breaks down the amino acid asparagine and may stop the growth of cancer cells that need asparagine to grow. It may also kill cancer cells. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Blinatumomab is a drug used to treat certain types of B-cell acute lymphoblastic leukemia that are CD19 positive (expresses the protein CD19). Blinatumomab binds to CD19, which is found on most B cells (a type of white blood cell) and some types of leukemia cells. It also binds to a protein called CD3, which is found on T cells (another type of white blood cell). This may help the immune system kill cancer cells. Blinatumomab is a type of bispecific T-cell engager. Giving asparaginase Erwinia chrysanthemi and venetoclax in combination with blinatumomab may be safe, tolerable, and/or effective in treating patients with relapsed or refractory ALL.
Primary Outcome
Will be graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0. Will be summarized in terms of type (organ affected or laboratory determination), severity, attribution, time of onset, duration, probable association with the study treatment and reversibility or outcome by counts/ rates and 95% Clopper Pearson confidence interval (CI).
