Supportive care included epoetin alfa, romiplostim, iron, and vitamin supplementation. CONCLUSIONS This is the first known reported case that demonstrates the feasibility and effectiveness of a chemotherapy-free induction strategy using inotuzumab and blinatumomab for frontline treatment of Ph-negative B-ALL in Jehovah's Witness patients. It shows that MRD negativity can be safely achieved without cytotoxic chemotherapy or transfusion support and supports the use of the ALLIANCE A041703 trial regimen as a treatment model for this unique and underserved patient group.

Consistent with these changes in priming, platelets aged in vitro exhibit increasing expression of multiple pro-apoptotic proteins including BIM, BAK and PUMA along with increasing cleaved caspase 3. Leveraging the lower BCL-XL dependence of young platelets, stimulation of de novo platelet production with the thrombopoietin receptor agonist romiplostim prevents BH3 mimetic-induced thrombocytopenia in vivo and may prevent severe platelet loss in patients treated with BCL-XL inhibitors.
