Clinical trial failure risk: Phase 2/3 trials have 30-40% historical success rates in oncology; negative efficacy or safety data could render pipeline worthless
Regulatory approval uncertainty: FDA may require additional trials, reject applications, or impose restrictive labels limiting commercial opportunity
Reimbursement pressure: Payers increasingly scrutinizing high-cost oncology drugs, potentially limiting pricing power even post-approval
Patent cliff and intellectual property challenges: Composition of matter patents and regulatory exclusivity determine commercial runway and generic competition timing
Menin inhibitor competition: Syndax's revumenib is in similar development stage with potentially faster timeline; first-to-market advantage critical in rare disease oncology
Standard of care evolution: Venetoclax combinations and other targeted therapies improving outcomes in NPM1/KMT2A populations, raising efficacy bar for approval
Larger pharma entrants: Companies like Janssen, Novartis have greater resources for clinical development and commercial infrastructure if they prioritize menin inhibitor programs
Cash runway risk: With $80-100M annual burn and current cash position, company likely needs additional financing within 12-18 months; dilution risk to existing shareholders
Equity financing dependency: Market conditions for biotech IPOs and follow-on offerings volatile; adverse sentiment could force financing at unfavorable terms or delay critical trials
Minimal debt capacity: Low revenue and negative cash flow limit ability to raise non-dilutive debt financing; reliance on equity markets creates valuation vulnerability
