Dyne Therapeutics Inc. is eyeing accelerated approval for its myotonic dystrophy type 1 treatment after reviewing new results from a phase I/II study. DYNE-101, an oligonucleotide antisense and DMPK gene modulator, produced results on disease biomarkers that included DMPK and splicing correction, disease progression reversal on several functional endpoints and a favorable safety profile. The accelerated approval submission could come in the first half of 2026.
Arrakis Therapeutics Inc. has presented data on its RNA-targeted small-molecule (rSM) drug program for the treatment of myotonic dystrophy type 1 (DM1). The company’s proprietary RNA‐specific chemical, biological and structural methods and RNA-directed medicinal chemistry enabled structure-based small-molecule drug design targeting the trinucleotide (CUG) repeat expansion in the mRNA of DMPK (myotonic dystrophy protein kinase) that drives DM1 pathology.
Rising from a $51 million series A round a year ago to a $1.1 billion acquisition, Kate Therapeutics Inc. has stepped under the umbrella of Novartis AG, which gains preclinical adeno-associated virus-based gene therapies for neuromuscular diseases.
Shares of Dyne Therapeutics Inc. (NASDAQ:DYN) closed May 20 at $35.38, up $7.70, or 28%, on word of positive data from the phase I/II Achieve trial of DYNE-101 in myotonic dystrophy type 1 (DM1) and the phase I/II Deliver effort with DYNE-251 in Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping. CEO John Cox, who joined Waltham, Mass.-based Dyne eight weeks ago, said he “couldn’t be more proud to be part of this team.” Studies are ongoing, but new data with regard to DM1 as well as DMD showed a “compelling” impact, Dyne said, plus satisfying safety profiles.
Arthex Biotech SL has received FDA clearance to initiate the phase I/IIa Arthemir study of ATX-01 for the treatment of myotonic dystrophy type 1 (DM1).
With positive initial phase I/II data in hand from two trials, Dyne Therapeutics Inc. plans to report more findings and start enrolling registrational cohorts in both studies by the end of this year for DYNE-101 in myotonic dystrophy type 1 (DM1) and a study called Deliver with DYNE-251 in Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping.
Pepgen Inc. has received a no objection letter from Health Canada for its clinical trial application (CTA) to initiate a phase I study of PGN-EDODM1 in patients with myotonic dystrophy type 1 (DM1). Initial data from the study are expected next year.
