Romiplostim-induced MF in a mouse model demonstrated extensive bone marrow (BM) CHI3L1 mRNA expression, which was reversed by clodronate treatment. A culture assay revealed that high CHI3L1 concentrations promoted extracellular matrix production by fibroblast cell lines, and that a CHI3L1-neutralizing antibody abrogated this effect. These results indicate the importance of CHI3L1 in the association between fibrocytes and fibroblasts in MF and could be a focus for future treatment.
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.
