Gene therapy manufacturing complexity and scalability - AAV vector production requires specialized facilities with limited global capacity, creating supply chain bottlenecks and high COGS risk
Regulatory uncertainty for novel gene therapies - FDA requiring longer-term durability data (5-10 years) before approval, potential for clinical holds due to immune responses or off-target effects
Reimbursement challenges for ultra-high-cost therapies - payers increasingly resistant to $2-3M one-time treatments without outcomes-based contracts or installment payment structures
Sarepta Therapeutics' established DMD franchise with approved exon-skipping therapies and competing gene therapy programs creates high bar for differentiation
Pfizer's fordadistrogene movaparvovec gene therapy program in late-stage development with potentially superior micro-dystrophin construct and manufacturing scale
Risk of becoming 3rd or 4th entrant in DMD gene therapy market with limited remaining patient population and physician preference already established
Equity dilution risk from future capital raises - pre-revenue biotechs typically require 3-5 financing rounds before commercialization, diluting existing shareholders 70-90%
Cash runway pressure if clinical trials encounter delays - current $100M annual burn provides approximately 2-3 year runway based on current ratio, but trial extensions could accelerate financing needs
Negative ROE of -73.6% and ROA of -61.0% reflect accumulated losses and capital consumption inherent to clinical-stage model
