In certain embodiments, the present disclosure provides a method for treating a V617F-related disorder in a patient in need thereof, comprising the step of administering to said patient a compound of the disclosure, or a pharmaceutically acceptable composition thereof.
[0585] In certain embodiments, the present disclosure provides a method of treating cancer in a patient in need thereof, the method comprising administering to the patient a therapeutically effective amount of a compound (e.g., a compound of Formula (I-XIII)), or a pharmaceutically acceptable salt thereof. In some embodiments, the cancer is a myeloproliferative disease or disorder (e.g., a myeloproliferative neoplasm).
[0586] Myeloproliferative diseases (MPD) are multipotent hematopoietic stem cell disorders characterized by excess production of various blood cells. MPNs include polycythemia vera (PV), essential thrombocythemia (ET), and idiopathic myelofibrosis (IMF). JAK2 V617F mutation is reported in about 95% of patients with PV, in 35% to 70% of patients with ET, and 50% of patients with IMF. Also, JAK2 exon 12 mutations are detected in some of the V617F -negative PV patients (Ma et al., J. Mol. Diagn., 11 : 49-53, 2009). In some embodiments, the compounds of the disclosure can be useful in the treatment of myeloproliferative disorders (e.g., myeloproliferative neoplasms) in a patient in need thereof, such as polycythemia vera, essential thrombocythemia, myelofibrosis with myeloid metaplasia (MMM), primary myelofibrosis (PMF), chronic myelogenous leukemia (CML), chronic myelomonocytic leukemia (CMML), hypereosinophilic syndrome (HES), systemic mast cell disease (SMCD), and the like.
[0587] In some embodiments, the myeloproliferative disorder is a myeloproliferative neoplasm.
[0588] In some embodiments, the myeloproliferative disorder is myelofibrosis (e.g., primary myelofibrosis (PMF) or post polycythemia vera / essential thrombocythemia myelofibrosis (Post-PV / ET MF)). In some embodiments, the myeloproliferative disorder is primary myelofibrosis (PMF). In some embodiments, the myeloproliferative disorder is post- essential thrombocythemia myelofibrosis (Post-ET MF). In some embodiments, the myeloproliferative disorder is post polycythemia vera myelofibrosis (Post-PV MF). In some embodiments, the myeloproliferative disorder is selected from primary myelofibrosis (PMF), polycythemia vera (PV), and essential thrombocythemia (ET). In some embodiments, the myeloproliferative neoplasm is primary myelofibrosis (PMF). In some embodiments, the myeloproliferative
[0589] IPTS / 200134983.3 PCT / US25 / 48136 26 September 2025 (26.09.2025) neoplasm is polycythemia vera (PV). In some embodiments, the myeloproliferative neoplasm is essential thrombocythemia (ET).
[0590] Myeloproliferative diseases include disorders of a bone marrow or lymph nodederived cell type, such as a white blood cell. A myeloproliferative disease can manifest by abnormal cell division resulting in an abnormal level of a particular hematological cell population. The abnormal cell division underlying a proliferative hematological disorder is typically inherent in the cells and not a normal physiological response to infection or inflammation. Leukemia is a type of myeloproliferative disease. Exemplary myeloproliferative diseases include, but are not limited to, acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), myelodysplastic syndrome (MDS), chronic myeloid leukemia (CML), hairy cell leukemia, leukemic manifestations of lymphomas, multiple myeloma, polycythemia vera (PV), essential thrombocythemia (ET), idiopathic myelofibrosis (IMF), hypereosinophilic syndrome (HES), chronic neutrophilic leukemia (CNL), myelofibrosis with myeloid metaplasia (MMM), chronic myelomonocytic leukemia (CMML), juvenile myelomonocytic leukemia, chronic basophilic leukemia, chronic eosinophilic leukemia, systemic mastocytosis (SM), and unclassified myeloproliferative diseases (UMPD or MPD-NC). Lymphoma is a type of proliferative disease that mainly involves lymphoid organs, such as lymph nodes, liver, and spleen. Exemplary proliferative lymphoid disorders include lymphocytic lymphoma (also called chronic lymphocytic leukemia), follicular lymphoma, large cell lymphoma, Burkitt's lymphoma, marginal zone lymphoma, lymphoblastic lymphoma (also called acute lymphoblastic lymphoma).

[0599] In some embodiments, the compounds of the disclosure can be useful in the treatment of myelodysplastic syndrome (MDS) in a patient in need thereof. In some embodiments, said patient having the myelodysplastic syndrome (MDS) is red blood cell transfusion dependent.
[0600] As used herein, myelodysplastic syndromes are intended to encompass heterogeneous and clonal hematopoietic disorders that are characterized by ineffective hematopoiesis on one or more of the major myeloid cell lineages. Myelodysplastic syndromes are associated with
[0601] 128
[0602] IPTS / 200134983.3 PCT / US25 / 48136 26 September 2025 (26.09.2025) bone marrow failure, peripheral blood cytopenias, and a propensity to progress to acute myeloid leukemia (AML). Moreover, clonal cytogenetic abnormalities can be detected in about 50% of cases with MDS. In 1997, The World Health Organization (WHO) in conjunction with the Society for Hematopathology (SH) and the European Association of
[0603] 5 Hematopathology (EAHP) proposed new classifications for hematopoietic neoplasms (Harris, et al., J Clin Oncol 1999;17:3835-3849; Vardiman, et al., Blood 2002;100:2292-2302). For MDS, the WHO utilized not only the morphologic criteria from the French- American-British (FAB) classification but also incorporated available genetic, biologic, and clinical characteristics to define subsets of MDS (Bennett, et al., Br. J. Haematol. 1982;51 : 189-199). io In 2008, the WHO classification of MDS (Table 2) was further refined to allow precise and prognostically relevant subclassification of unilineage dysplasia by incorporating new clinical and scientific information (Vardiman, et al., Blood 2009;114:937-951; Swerdlow, et al., WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues.4th Edition. Lyon France: IARC Press; 2008:88-103; Bunning and Germing, “Myelodysplastic
