Imatinib has revolutionized the treatment of chronic myeloid leukemia (CML) and is the current standard of care in the treatment of patients with newly diagnosed CML. However, about 30% of patients still show drug resistance or disease progression. Currently, the most widely studied mechanism of TKI resistance in CML patients is mutations in the ABL kinase region. So far, more than 100 kinase domain mutations have been found in disease progression and imatinib resistance. It is estimated that more than 25% of CML patients will change TKI at least once in their lifetime due to drug resistance or intolerance. The 2020 edition of the "Guidelines for the Diagnosis and Treatment of Chronic Myelogenous Leukemia in China" proposes that patients with F317L/V/I/C, V299L and T315A mutations are more likely to obtain clinical efficacy by switching to the second-generation TKI nilotinib; patients with Y253H, E255K/V and F359C/V/I mutations are more likely to obtain clinical efficacy by switching to the second-generation TKI dasatinib; patients with T315I mutations are resistant to both nilotinib and dasatinib. Flumatinib has been shown to be a more potent inhibitor of BCR-ABL1 tyrosine kinase than imatinib. In vitro studies, it has shown that flumatinib inhibits wild-type and common BCR-ABL mutations(Q252H, V299L, F317L/I, M351T, H396P, etc.) more potently, and the anti-mutation spectrum of flumatinib is similar to nilotinib. Therefore, this study is designed to provide clearer guidance for patients with specific BCR-ABL kinase point mutations during CML treatment.

Bosutinib is a 2nd generation tyrosine kinase inhibitor that has shown promising results from first up to fourth line treatment in patients with in chronic phase of chronic myelogenous leukaemia. Most patients discontinuing the treatment with Bosutinib do so because of side effects occuring early after starting the treatment. A step in dosing scheme could improve these early toxicities. The aim of this study therefore is to demonstrate that temporary lowering of the Bosutinib dose during early treatment may help to reduce or prevent side effects while preserving efficacy.

The purpose of this study is to test the safety of a new combination of three oral drugs in Ph+ ALL. These drugs are dexamethasone, dasatinib, and ruxolitinib. All three drugs have been studied before in humans. This is a phase I study in which ruxolitinib dose will start low for the first patient together with dexamethasone plus dasatinib. If this dose does not cause a bad side effect, the ruxolitinib dose will slowly be made higher as new patients take part in the study. This will help the investigators find the right dose of ruxolitinib to give together with dexamethasone and dasatinib that will be used in future studies
