DALLAS - Taysha Gene Therapies, Inc. (NASDAQ:TSHA), a clinical-stage company specializing in gene therapies for central nervous system diseases, has received approval from the Independent Data Monitoring Committee (IDMC) to increase the dosage in its ongoing REVEAL Phase 1/2 trials for Rett syndrome, a rare neurodevelopmental disorder. The company announced today that it will proceed to the high dose cohort in its adolescent and adult trial and will dose the second patient in the pediatric trial's low dose cohort.
The IDMC's green light comes after reviewing clinical data from patients already dosed with TSHA-102, the investigational gene therapy. With the approval, the company is set to administer the high dose of 1x1015 total vg to the first patient in the second quarter of 2024, with initial data expected in the latter half of the year.
In addition to the dosage escalation, Taysha has expanded its REVEAL trial into the United States, following a submission to the U.S. Food and Drug Administration (FDA). The trial, which was previously conducted in Canada, is evaluating the safety and preliminary efficacy of TSHA-102 in females aged 12 years and older with Rett syndrome.
TSHA-102 leverages a novel miRNA-Responsive Auto-Regulatory Element (miRARE) technology, aiming to regulate the levels of MECP2, a critical gene for neuronal and synaptic function. The therapy has been granted Fast Track, Orphan Drug, and Rare Pediatric Disease designations by the FDA and Orphan Drug designation by the European Commission.
The pediatric trial, also set to proceed with dosing its second patient in the first quarter of 2024, is focusing on determining the maximum tolerated dose (MTD) and maximum administered dose (MAD) in young patients. Initial data from the first cohort is expected mid-2024, providing insights into the therapy's safety and efficacy.
Rett syndrome, caused by mutations in the MECP2 gene, primarily affects females and leads to severe intellectual disabilities, loss of communication, and motor impairments. Currently, there are no approved treatments that address the genetic cause of the disorder, which affects an estimated 15,000 to 20,000 patients across the U.S., EU, and U.K.
Taysha's updates on its clinical trials are based on a press release statement.
