Phase 2 Study of Nilotinib 400 Mg Twice Daily in Newly Diagnosed Patients with Accelerated Phase of Chronic Myeloid Leukemia, Results after 5.7 Years of Follow-up
CONCLUSIONNilotinib is safe and highly effective in patients with AP-CML, and induces fast and durable responses. More than 50% of patients can achieve MR4.5.

Real-World Comparisons of Cardiovascular Events between Different Tyrosine Kinase Inhibitors Among Patients with Chronic Myeloid Leukemia
CONCLUSION: CP-CML patients treated with different TKIs (ponatinib, bosutinib, imatinib, dasatinib, and nilotinib) did not have different incidence of cardiovascular events (MACE, AOEs, VTEs) in this small cohort of real-world patients with ≥6-month of follow-up. The results were consistent among patients with prior use of one and two TKI types.DisclosuresLevy: Takeda (Millennium Pharmaceuticals, Inc.): Consultancy. Xie: STATinMED Research: Employment.

Therapeutic effect of low-dose imatinib on pulmonary arterial hypertension in dogs.
Abstract This was a pilot study to determine the effectiveness of low-dose imatinib therapy for hemodynamic disturbances, including pulmonary arterial hypertension (PAH), and clinical manifestations caused by chronic heart failure in dogs. Six client-owned dogs with PAH were administered imatinib mesylate orally, 3 mg/kg body weight q24h, for 30 d. Physical examination, blood biochemical tests, radiography, and Doppler echocardiography were performed prior to imatinib administration and again 30 days after administration. Clinical scores were significantly reduced after imatinib treatment. Systolic pulmonary arter...

Impact of lowering pulmonary vascular resistance on right and left ventricular deformation in pulmonary arterial hypertension
ConclusionsPAH is associated with impaired biventricular deformation. Reduction in PVR is associated with improvements in both RV and LV deformation, coupled to improvements in MPAP and stroke volume index, with LV global and septal CS the strongest correlates of these changes. RV FWLS is sensitive to treatment effect, demonstrating greater improvement with imatinib compared with placebo.Trial registration: NCT00902174

Cardiovascular Complications of Targeted Therapies for Chronic Myeloid Leukemia
Opinion statementThe development of tyrosine kinase inhibitors (TKIs) dramatically changed the treatment landscape for many different cancers including chronic myeloid leukemia (CML). With the introduction of imatinib, the first TKI developed and approved to effectively treat CML, patient survival has increased dramatically and, in some cases, this fatal cancer can be managed as a chronic disease. Since the approval of imatinib in 2002, four additional TKIs have been developed to treat this disease including the second-generation TKIs nilotinib, dasatinib, and bosutinib and the third-generation TKI ponatinib. Despite their...

Asciminib, a Specific Allosteric BCR-ABL1 Inhibitor, in Patients with Chronic Myeloid Leukemia Carrying the T315I Mutation in a Phase 1 Trial
We report results from the largest cohort: pts with confirmed T315I mut at screening (tested locally by Sanger sequencing) and treated with asciminib 200 mg BID, which showed the most robust efficacy (data cutoff: April 30, 2018).At the data cutoff, treatment was ongoing in 23/24 pts (95.8%) (Table); 1 pt (4.2%) had ended treatment. Median duration of follow-up and asciminib exposure were both 28.5 wk (range, 0.1-74.7 wk). Most pts had received multiple prior TKIs, and PON was the most recent TKI for 12/24 (50.0%). Pts who were PON naive had underlying conditions, such as CV risk factors. Eight of 24 pts achieved MMR by 24...
