Myelodysplastic syndrome (MDS) is a group of hematopoietic disorders with limited treatment options. Anemia is a common symptom in MDS, and although erythropoiesis-stimulating agents such as erythropoietin, lenalidomide, and luspatercept are available to treat anemia, many MDS patients do not respond to these first-line therapies. Therefore, alternative drug development strategies are needed to improve therapeutic efficacy. Splicing modulators to correct splicing-related defects have shown promising results in clinical trials. Targeting differentiation of early erythroid progenitors to increase the erythroid output in MDS is another novel approach, which has shown encouraging results at the pre-clinical stage. Together, these therapeutic strategies provide new avenues to target MDS symptoms untreatable previously.
骨髓增生异常综合征(MDS)是一组造血系统疾病,治疗方法有限。贫血是 MDS 的常见症状,虽然促红细胞生成素、来那度胺和芦可替尼等促红细胞生成刺激剂可用于治疗贫血,但许多 MDS 患者对这些一线治疗无反应。因此,需要开发替代药物治疗策略以提高治疗效果。剪接调节剂纠正剪接相关缺陷在临床试验中取得了有希望的结果。针对早期红系祖细胞的分化,增加 MDS 中的红系输出是另一种新方法,在临床前阶段取得了令人鼓舞的结果。总之,这些治疗策略为以前无法治疗的 MDS 症状提供了新的靶向途径。
