Introduction: Myelodysplastic syndromes Myelodysplastic syndromes: (my-eh-lo-diss-PLASS-tik SIN-dromez) A group of disorders where the bone marrow does not work well, and the bone marrow cells fail to make enough healthy blood cells. Myelo refers to the bone marrow. Dysplastic means abnormal growth or development. People with MDS have low blood cell count for at… /neoplasms (MDS) are a heterogeneous group of hematologic malignancies that are stratified into high-risk (HR-MDS) and low-risk (LR-MDS) categories. Until recently, LR-MDS has been typically managed by supportive measures and erythropoiesis-stimulating agents (ESAs); whereas management of HR-MDS typically included hypomethylating agents and allogeneic hematopoietic stem cell transplant. However, the limited rates and durations of response observed with these interventions prompted the search for targeted therapies to improve the outcomes among patients with MDS.
Areas covered: Here, we review the current landscape of targeted therapies in MDS. These include pyruvate kinase and hypoxia-inducible factor (HIF) activators; TGF-beta, telomerase, BCL2 and isocitrate dehydrogenase (IDH) inhibitors; as well as novel approaches targeting inflammation, pyroptosis, immune evasion, and RNA splicing machinery.
Expert opinion: This review highlights the progress and challenges in MDS treatment. Despite some promising results, many therapies remain in early development or have faced setbacks, emphasizing the need for a more comprehensive understanding of the disease's pathobiology. Continued research into targeted therapies, homogenous clinical trial clinical trial: A type of research study that tests how a drug, medical device, or treatment approach works in people. There are several types of clinical trials. Treatment trials test new treatment options. Diagnostic trials test new ways to diagnose a disease. Screening trials test the best way to detect a… designs, as well as increased incorporation of molecular prognostic tools and artificial intelligence into trial design are essential for developing effective treatments for MDS and improving patient outcomes.
Keywords: Myelodysplastic syndromes/neoplasms (MDS); azacitidine azacitidine: It works by reducing the amount of methylation in the body. Methylation is a process that acts like a switch to turn off or “silence” genes in certain cells. When these genes (called tumor suppressor genes) are turned off, MDS cells and cancer cells can grow freely. Azacitidine is approved by the U… ; clinical trials clinical trials: Clinical research is at the heart of all medical advances, identifying new ways to prevent, detect or treat disease. If you have a bone marrow failure disease, you may want to consider taking part in a clinical trial, also called a research study.

Before taking RYTELO, tell your healthcare provider about all your medical conditions, including if you: are pregnant or plan to become pregnant. RYTELO may harm your unborn baby and may cause loss of pregnancy.
