FGFR1-rearranged myeloid/lymphoid neoplasms are a rare and highly heterogeneous hematological malignancy, mainly manifested as myeloproliferative neoplasms (MPNs) or acute leukemia, including T cells or B cells Cell lymphoblastic leukemia/lymphoma (T-cell or B-cell-ALL/LBL), acute myeloid leukemia (AML) and mixed cell leukemia (MPAL).~To date, there is no standard treatment. Conventional chemotherapy is frequently ineffective. The only curative option is thought to be allogeneic HSCT at present, TKIs may offer a therapeutic alternative in patients not eligible for allogeneic HSCT or to bridge the time between diagnosis and allogeneic HSCT.~Third-generation TKIs Olverembatinib is a pan- FGFR1 kinase inhibitor, and is supposed to be effective to achieve bone marrow remission in FGFR1-rearranged myeloid/lymphoid neoplasms.
FGFR1-rearranged myeloid/lymphoid neoplasms are a rare hematologic malignancy with very poor outcome despite intensive chemotherapy. The only curative option is thought to be allogeneic hematopoietic stem cell transplantation (HSCT) in remission.~This phase II study is aimed to evaluate the efficacy of Olverembatinib, consolidated with HSCT in the treatment of FGFR1-rearranged myeloid/lymphoid neoplasm.
