Binary regulatory risk - FDA rejection or clinical trial failure would eliminate near-term value given single lead asset concentration
Orphan drug market size constraints - DMD cardiomyopathy addressable market may be 2,000-4,000 patients in US, limiting peak revenue potential even with approval
Reimbursement uncertainty for novel cell therapies - payers increasingly scrutinizing high-cost rare disease treatments despite orphan drug pricing flexibility
Sarepta Therapeutics and other established DMD players have gene therapy and exon-skipping approaches with earlier market entry and established relationships
Larger biotechs (Pfizer, Roche) developing competing DMD cardiac therapies with superior capital resources for trials and commercialization
Technology risk - exosome and cell therapy platforms face manufacturing scalability challenges and potential immunogenicity issues
Cash burn risk - negative $15-20M annual operating cash flow with $1B market cap suggests potential near-term dilutive financing if regulatory timelines extend
Going concern risk if clinical setbacks occur - limited revenue diversification means single trial failure could trigger liquidity crisis
Equity dilution risk - pre-revenue biotechs typically require multiple financing rounds, with current shareholders facing 30-50% dilution risk through commercialization
