Dyne Therapeutics stock gains as DYNE-251 receives FDA breakthrough designation

Investing.com - Dyne Therapeutics (NASDAQ:DYN), currently trading at $10.28, received Breakthrough Therapy Designation from the FDA for DYNE-251, its next-generation exon 51-skipping therapy for Duchenne muscular dystrophy (DMD). The $1.46 billion market cap biotech company shows potential despite InvestingPro data indicating weak financial health scores.

The breakthrough designation indicates the FDA views DYNE-251 as a "substantial improvement over available therapy" compared to existing treatment Exondys-51, according to Stifel, which maintained its Buy rating and $36.00 price target on the stock.

The designation suggests the pathway for accelerated approval based on dystrophin production remains open despite recent leadership changes at the FDA that had raised investor concerns about the agency’s stance on surrogate endpoints in DMD.

Stifel noted that the breakthrough designation validates the 3% dystrophin improvement (7% adjusted) and favorable functional data from Dyne’s Phase 1/2 study of DYNE-251.

While investor focus has primarily been on Dyne’s DM1 program, Stifel believes the DMD program deserves more attention as the company approaches registrational data expected in late 2025, which could provide "meaningful potential upside" following Dyne’s recent financing activities.

In other recent news, Dyne Therapeutics has announced several significant developments. The company reported a shift in its registrational study for its DYNE-101 program, focusing on visual hand opening time (vHOT) as a primary endpoint. This change led Stifel to lower its price target for Dyne Therapeutics from $66.00 to $36.00, although the firm maintained a Buy rating, suggesting a clearer regulatory path forward. Additionally, Dyne has secured a $275 million loan facility from Hercules Capital (NYSE:HTGC), with $100 million available upfront and the remainder contingent on meeting specific milestones. The company also announced plans to raise $200 million through a public offering of common stock, with shares priced at $8.25 each. Following these financial activities, Bernstein adjusted its price target from $13.00 to $11.50 while maintaining a Market Perform rating. In another development, Jones Trading initiated coverage on Dyne Therapeutics with a Buy rating and a $30 price target, citing upcoming data releases for Exon 51 Duchenne Muscular Dystrophy and Myotonic Dystrophy Type 1. Meanwhile, H.C. Wainwright reiterated its Buy rating and a $38.00 price target, noting the potential for accelerated approval of DYNE-101 using the vHOT endpoint.
