Dyne Therapeutics Inc (DYN)

In October 2025, Dyne Therapeutics' stock surged following Novartis's acquisition of Avidity Biosciences, but it dropped after Oppenheimer downgraded the company due to concerns over the ACHIEVE study. In September 2025, CEO John Cox sold 2,640 shares of Dyne Therapeutics stock. In August 2025, Dyne Therapeutics announced FDA Breakthrough Therapy Designation for DYNE-251 in Duchenne Muscular Dystrophy (DMD). In July 2025, the company reported quarterly earnings of ($0.97) per share, beating analysts' consensus estimates. In June 2025, Dyne Therapeutics announced that the FDA granted Breakthrough Therapy Designation to DYNE-101 for the treatment of myotonic dystrophy type 1 (DM1) and updated its plan for obtaining U.S. Accelerated Approval for DYNE-101, revising the primary endpoint in the ACHIEVE trial to video hand opening time (vHOT).

Dyne Therapeutics' products do not exhibit typical demand seasonality, as demand is driven by the prevalence and progression of chronic diseases rather than seasonal factors. The company's revenue generation is currently non-existent, and its financial success will depend on the successful clinical progression and regulatory approval of its drug candidates. Demand for its future products will be consistent and ongoing for patients requiring treatment for these conditions.

Dyne Therapeutics, Inc. is a clinical-stage biotechnology company focused on creating therapies for genetically driven neuromuscular diseases, utilizing its FORCE™ platform to deliver oligonucleotide therapeutics to muscle tissue and the CNS. Its pipeline includes DYNE-101 for myotonic dystrophy type 1 (DM1), DYNE-251 for Duchenne muscular dystrophy (DMD), DYNE-302 for facioscapulohumeral muscular dystrophy (FSHD), and DYNE-401, with plans to expand into rare skeletal, cardiac, and metabolic muscle diseases. DYNE-101 is being evaluated in the Phase 1/2 ACHIEVE trial, consisting of an antisense oligonucleotide conjugated to a fragment antibody to reduce toxic nuclear DMPK RNA. DYNE-251 is being evaluated in the DELIVER trial for DMD patients amenable to exon 51 skipping and has received Orphan Drug Designation in Japan and FDA Breakthrough Therapy Designation.

Dyne Therapeutics is headquartered in Waltham, Massachusetts, United States. The company has employees across North America, Europe, and Asia, indicating a global operational reach.

Dyne Therapeutics' brand reputation has been positively influenced by advancements in clinical trials and FDA Breakthrough Therapy Designations for DYNE-101 and DYNE-251, as well as positive one-year clinical data for DYNE-101. Concerns have arisen from Oppenheimer's stock downgrade due to the small cohort size and statistical variability in the Phase 1/2 ACHIEVE study, and a change in the primary endpoint for the DYNE-101 trial also led to a stock drop.

Dyne Therapeutics has significant institutional ownership, with 424 institutional owners holding approximately 98.68% of the company. Major institutional owners include RA Capital Management, L.P., Janus Henderson Group Plc, and Atlas Venture Life Science Advisors, LLC. Individual ownership accounts for a smaller portion, around 0.61%, while corporate insiders own 14.14% of the company's stock.
