DTx Pharma Receives FDA Orphan Drug Designation for DTx-1252 for the Treatment of Charcot-Marie-Tooth Disease Type 1A (CMT1A)

8 June 2023

DTx Pharma, a biotechnology company addressing the delivery challenges of oligonucleotide therapeutics with its Fatty Acid Ligand Conjugated OligoNucleotide platform, today announced that the United States Food and Drug Administration (FDA) has granted Orphan Drug Designation to DTx-1252, an investigational FALCON small interfering RNA (siRNA) therapeutic for the treatment of Charcot-Marie-Tooth Disease Type 1A (CMT1A). CMT1A is a progressive, neuromuscular, autosomal-dominant disease that leads to life-long loss of muscle function and disability.

"We are pleased to receive Orphan Drug Designation from the FDA for DTx-1252. Patients living with CMT1A are in urgent need of treatment and this represents a significant step forward for the patients and the DTx team as we advance DTx-1252 toward the clinic," said Artie Suckow, Ph.D., co-founder and CEO of DTx Pharma. "DTx-1252 targets the underlying genetic lesion of the disease and leverages our FALCON platform to unlock the promise of RNAi therapeutics. We look forward to the continued development of DTx-1252."

The FDA Office of Orphan Products Development (OOPD) provides orphan status to drugs and biologics which are intended to treat, diagnose or prevent rare diseases that affect fewer than 200,000 people in the U.S.

Currently, there are no approved therapeutics addressing PMP22, the underlying genetic cause of CMT1A, for the estimated 150,000 patients living with the debilitating disease in the U.S. and Europe. DTx-1252, is a novel, potential first-in-class candidate targeting PMP22.  The asset boasts a robust preclinical package, demonstrating reversal of disease in preclinical rodent models and translation to higher species with IND-enabling studies near completion.
