RNA therapeutics for the treatment of blood disorders

Blood disorders are defined as diseases related to the structure, function, and formation of blood cells. These diseases lead to increased years of life loss, reduced quality of life, and increased financial burden for social security systems around the world. Common blood disorder treatments such as using chemical drugs, organ transplants, or stem cell therapy have not yet approached the best goals, and treatment costs are also very high. RNA with a research history dating back several decades has emerged as a potential method to treat hematological diseases. A number of clinical trials have been conducted to pave the way for the use of RNA molecules to cure blood disorders. This novel approach takes advantage of regulatory mechanisms and the versatility of RNA-based oligonucleotides to target genes and cellular pathways involved in the pathogenesis of specific diseases. Despite positive results, currently, there is no RNA drug to treat blood-related diseases approved or marketed. Before the clinical adoption of RNA-based therapies, challenges such as safe delivery of RNA molecules to the target site and off-target effects of injected RNA in the body need to be addressed. In brief, RNA-based therapies open novel avenues for the treatment of hematological diseases, and clinical trials for approval and practical use of RNA-targeted are crucial.
