Program leverages novel miRARE platform technology used to control transgene expression on a cellular basis
TSHA-102 anticipated to submit Investigational New Drug application in 2021
Rett syndrome is one of the most common genetic causes of severe intellectual disability worldwide, with a prevalence of over 25,000 cases in the
“Patients with Rett syndrome are currently managed with symptomatic treatments as there are no therapies approved to treat the underlying cause of disease,” said
Rett syndrome is caused by mutations in the MECP2 gene. TSHA-102 is designed to deliver a healthy version of the MECP2 gene as well as the miRNA-Responsive Auto-Regulatory Element, miRARE, platform technology to control the level of MECP2 expression. “TSHA-102 represents an important step forward in the field of gene therapy, where we are leveraging a novel regulatory platform called miRARE to prevent the overexpression of MECP2,” said
The FDA defines a rare pediatric disease as a serious or life-threatening disease in which the disease manifestations primarily affect individuals aged from birth to 18 years. Pediatric diseases recognized as "rare" affect under 200,000 people in the
Orphan drug designation is granted by the
“Obtaining these designations is a validation of decades-long work to identify and optimize a potential gene therapy treatment for this devastating disease,” said RA Session II, President, CEO and Founder of Taysha. “We are also excited to advance our miRARE platform whereby regulated expression of a transgene is possible on a cellular basis. The miRARE platform has broad applicability across a wide range of monogenic CNS disorders where there is a need to control transgene expression.”
About
About miRARE
For disorders that require replacement of dose-sensitive genes, we have combined high-throughput microRNA, or miRNA, profiling and genome mining to create miRNA-Responsive Auto-Regulatory Element, or miRARE, our novel miRNA target panel. This approach is designed to enable our product candidates to maintain safe transgene expression levels in the brain. This built-in regulation system is fully endogenous, and does not require any additional exogenous drug application. Instead, the miRARE system utilizes endogenous transgene-responsive miRNA to downregulate transgene expression in the event that overexpression occurs. miRARE may be applicable to a range of diseases where overexpression of a therapeutic transgene is a concern.
