Clinical trial failure risk - Phase 2b/3 trials have 30-40% historical success rates in fibrotic diseases; negative efficacy or safety data would eliminate near-term value
Regulatory pathway uncertainty - FDA approval standards for IPF therapies require demonstrating meaningful FVC improvement and survival benefits over 12-18 month trials
Competitive landscape evolution - established therapies (Ofev, Esbriet) set high efficacy bars; emerging competitors targeting similar integrin pathways could commoditize mechanism
Capital markets access risk - need for $300-500M additional funding to reach commercialization creates dependence on favorable biotech financing windows
Boehringer Ingelheim and Roche dominate IPF market with established sales infrastructure, physician relationships, and real-world efficacy data
Multiple clinical-stage competitors pursuing integrin-targeted and alternative fibrosis mechanisms (Galecto, Blade Therapeutics, Morphic Therapeutic) create crowded pipeline
Large pharma internal programs could leapfrog with superior efficacy, safety, or dosing convenience (oral vs. inhaled formulations)
Cash runway risk - $200M annual burn with $100M market cap implies imminent need for dilutive financing within 12-18 months absent partnership
Equity dilution risk - at current $0.40 price-to-book, future raises would significantly dilute existing shareholders; 50-100% dilution likely before commercialization
Going concern risk - if Phase 2b data disappoints or financing markets close, company may lack resources to complete development programs
