项目摘要

Leukemia is a bone marrow cancer involving developing white blood cells and often is associated with specific, recurrent chromosome translocations and inversions that generate fusion genes, which play critical roles in leukemogenesis. In this project, targeted treatments are being developed for a subgroup of leukemia based on current understanding of how leukemia develops at the molecular level. The core binding factor (CBF) subgroup of leukemia contains CBF fusion genes that have been shown to play critical roles in leukemia development. Current treatments for CBF leukemia are not optimal, with long-term survival at 50 percent. The research team conducted a small chemical library screen to find inhibitors that block CBF protein interactions. Through biochemical, cell culture and animal model studies, they identified three chemically related lead compounds. In particular, one of the three compounds has shown leukemia reduction capability similar to standard chemotherapy drugs in preliminary studies in a mouse CBF leukemia model. The researchers will complete efficacy studies in this mouse model, develop one or more backup compounds, optimize formulation, and perform pharmacokinetics and toxicology tests that will lead to clinical trials. TRND researchers have successfully optimized and demonstrated the utility of the animal disease model. TRND scientists are performing medicinal chemistry optimization to identify a compound suitable for formal preclinical development. Once such a compound is identified, TRND will conduct the necessary studies to support filing an Investigational New Drug application with the Food and Drug Administration.

白血病是一种涉及白细胞发育的骨髓癌，通常与特定的、反复发生的染色体易位和倒位有关，这些易位和倒位产生融合基因，在白血病发生中发挥着关键作用。在该项目中，根据目前对白血病在分子水平上如何发展的了解，正在开发针对白血病亚组的靶向治疗方法。白血病的核心结合因子 (CBF) 亚组含有 CBF 融合基因，这些基因已被证明在白血病的发展中发挥着关键作用。目前 CBF 白血病的治疗方法并非最佳，长期生存率为 50%。研究小组进行了小型化学库筛选，以寻找阻断 CBF 蛋白相互作用的抑制剂。通过生化、细胞培养和动物模型研究，他们鉴定了三种化学相关的先导化合物。特别是，在小鼠 CBF 白血病模型的初步研究中，这三种化合物中的一种显示出与标准化疗药物相似的降低白血病的能力。研究人员将在此小鼠模型中完成功效研究，开发一种或多种备用化合物，优化配方，并进行药代动力学和毒理学测试，以进行临床试验。 TRND 研究人员成功优化并证明了动物疾病模型的实用性。 TRND 科学家正在进行药物化学优化，以确定适合正式临床前开发的化合物。一旦确定了这种化合物，TRND 将进行必要的研究，以支持向食品和药物管理局提交研究性新药申请。
