The company will also grant underwriters a 30-day option to purchase up to an additional $30 million in shares.

The offering will be managed by joint book-running managers Morgan Stanley, Jefferies, Stifel, and Guggenheim Securities, with Jones acting as co-manager. The offering will be made through a shelf registration statement on Form S-3 previously filed with the SEC on March 5, 2024.

Dyne Therapeutics (Nasdaq: DYN) has secured a $275 million non-dilutive senior secured term loan facility from Hercules Capital (NYSE: HTGC). The financing includes $100 million funded upfront and additional tranches of up to $175 million tied to specific milestones.

The financing will support the advancement of Dyne's clinical programs: DYNE-101 for myotonic dystrophy type 1 (DM1) and DYNE-251 for Duchenne muscular dystrophy (DMD). The company plans potential U.S. Accelerated Approval submissions in 2026 and targets a potential U.S. launch in DMD by 2027.

The loan facility is structured in five tranches, including the initial $100 million, three milestone-dependent tranches totaling $115 million, and a final $60 million tranche subject to Hercules' approval. This structure provides Dyne with strategic flexibility through key inflection points in 2025 and 2026.

Dyne Therapeutics announced FDA Breakthrough Therapy Designation for DYNE-101 in treating myotonic dystrophy type 1 (DM1) and revealed plans for Accelerated Approval following positive clinical data. The company submitted a revised ACHIEVE trial protocol with video hand opening time (vHOT) as the primary endpoint for potential Accelerated Approval. The Registrational Expansion Cohort will enroll 60 participants with a 3:1 randomization to receive DYNE-101 6.8 mg/kg Q8W or placebo. New 12-month data showed sustained improvements in multiple endpoints, with vHOT improvement of 3.3 seconds vs placebo at 6 months and muscle strength improving from 10% at 6 months to 20% at 12 months. The company plans to complete enrollment in Q4 2025, with data expected mid-2026 to support U.S. Accelerated Approval submission in late 2026. DYNE-101 demonstrated a favorable safety profile with no serious treatment-related adverse events. Dyne's cash position of $677.5M is expected to fund operations into Q4 2026.

Dyne Therapeutics (Nasdaq: DYN), a clinical-stage neuromuscular disease company, has scheduled an investor conference call and webcast for June 17, 2025, at 8:00 a.m. ET to provide updates on DYNE-101, their therapeutic candidate for myotonic dystrophy type 1 (DM1). The company will release a press statement before the event. The webcast will be accessible through Dyne's website investor section, with presentation slides available and a replay option accessible for 90 days after the event. This announcement represents a standard corporate communication about an upcoming investor event focused on their DM1 program.

Dyne Therapeutics announced new preclinical data for DYNE-302 in treating facioscapulohumeral muscular dystrophy (FSHD), to be presented at the FSHD Society's International Research Congress in Amsterdam. The study showed promising results in a severe FSHD mouse model, where a single intravenous dose of DYNE-302 restored treadmill running ability and corrected muscle damage and inflammation markers. DYNE-302 uses TfR1-targeting technology to deliver siRNA specifically targeting DUX4 mRNA, a key factor in FSHD disease progression. The data suggests potential reversibility of severe skeletal muscle disease through DUX4 mRNA targeting. The presentation by Dr. Stefano Zanotti will take place on June 13, 2025, focusing on functional improvements and muscle transcriptomic changes in mouse models.

Dyne Therapeutics (DYN) reported Q1 2025 financial results and key developments for its lead programs. The company held an FDA Type C meeting for DYNE-101 in DM1 and initiated a Registrational Expansion Cohort of the ACHIEVE trial, targeting potential U.S. Accelerated Approval submission in H1 2026. The DELIVER trial's Registrational Expansion Cohort for DYNE-251 in DMD is fully enrolled, with potential BLA submission planned for early 2026.

Q1 2025 showed R&D expenses of $106.4M (up from $44.5M in Q1 2024) and net loss of $115.4M ($1.05 per share). The company strengthened its leadership team with key appointments including a new CFO, CBO, CSO, and CIO to support upcoming regulatory filings and potential commercial launches in 2027.

Dyne Therapeutics (Nasdaq: DYN) has received European Commission orphan drug designation for DYNE-251, its investigational therapy for Duchenne muscular dystrophy (DMD). The designation follows promising long-term clinical data presented in March 2025, showing sustained functional improvement through 18 months in the Phase 1/2 DELIVER trial.

The trial evaluates DYNE-251 in DMD patients amenable to exon 51 skipping. The company has completed enrollment of 32 patients in the registrational expansion cohort, with data expected in late 2025. Dyne plans to submit a Biologics License Application for US accelerated approval in early 2026.

The EU orphan designation provides benefits including reduced regulatory fees, clinical protocol assistance, and potential 10-year market exclusivity. DYNE-251 previously received FDA orphan drug and rare pediatric disease designations in March 2023.
