Brief summary: 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.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

1. Patients with newly diagnosed, progressed or relapsed myeloid/lymphoid neoplasms with FGFR1 rearrangement according to the WHO-2016 diagnostic criteria. Patients who have received allogeneic hematopoietic stem cell transplantation or ponatinib should be excluded.
2. ECOG score: MPNs patients, 0-3 points; AL patients, 0-2 points.
3. Expected survival period ≥12 weeks.
4. Willingness and ability to comply with study procedures and follow-up examination.

Exclusion Criteria:

1. Patients who have received allogeneic hematopoietic stem cell or ponatinib.
2. Human immunodeficiency virus (HIV) infection, or chronic infection with hepatitis B virus (HBsAg positive) or hepatitis C virus (anti-HCV positive).
3. Patients who are pregnant, planning to become pregnant or breastfeeding.
4. Patients who may not be able to complete all study visits or procedures required by the study protocol, including follow-up visits, and/or fail to comply with all required study procedures.
5. Patients who suffer from any condition or illness that, in the opinion of the investigator, would compromise patient safety or interfere with the evaluation of the safety of the research drug.
