China-based Suzhou GenAssist Therapeutic Co., Ltd has announced receiving clearance from the US Food and Drug Administration (FDA) to initiate clinical trials for its base editing drug, GEN6050X, as a treatment for Duchenne muscular dystrophy (DMD). This groundbreaking therapy represents a significant advancement in gene editing technologies for rare diseases.
GEN6050X: Innovative Base Editing Therapy
GEN6050X is an intravenous injection of a cytosine base editing drug delivered via a dual AAV9 vector. Specifically designed for DMD patients with exon 50 jumps, it is the world’s first base editing drug of its kind to enter clinical trials. Utilizing second-generation CRISPR-Cas9 technology, GEN6050X edits mutated DMD genes through a single systemic administration, permanently restoring dystrophin expression.
Clinical Progress and Initial Data
An investigator-initiated trial (ITT) for GEN6050X commenced at Peking Union Medical College Hospital in August of last year. Two patients have received treatment, including a 10-year-old patient who has completed a 6-month follow-up. Early data from this trial are expected to provide critical insights into the safety and efficacy of GEN6050X, paving the way for broader clinical development.-Fineline Info & Tech
