Clinical trial failure risk - Phase 2/3 trials for DYNE-101 and DYNE-251 may not demonstrate sufficient efficacy or acceptable safety profiles, resulting in program termination and significant value destruction
Regulatory approval uncertainty - FDA may require additional studies, reject applications, or impose restrictive labels limiting commercial potential even with positive trial data
Oligonucleotide delivery competition - rival platforms (exon-skipping, gene therapy, alternative conjugation technologies) may demonstrate superior efficacy or safety, obsoleting FORCE platform advantages
Sarepta Therapeutics dominates DMD market with approved exon-skipping therapies and gene therapy, creating high bar for differentiation and potential market share capture
Multiple well-funded competitors developing DM1 therapies including Avidity Biosciences (AOC-1001) and Entrada Therapeutics, racing to establish first-mover advantage in nascent market
Large pharma partnerships with competitors (e.g., Roche-PepGen collaboration) provide resource advantages in clinical development and commercialization capabilities
Cash runway risk - with approximately $330M cash as of late 2025 and $120-140M annual burn, company faces potential need for dilutive financing within 18-24 months absent partnership revenue or capital markets access
Equity dilution risk - pre-revenue biotechs typically require multiple financing rounds, and adverse market conditions or clinical setbacks could force raises at unfavorable valuations, significantly diluting existing shareholders
