Reimbursement uncertainty - CMS and private payers may establish inadequate reimbursement rates or restrictive coverage policies that limit commercial viability despite FDA approval
Limited patient population - Metastatic uveal melanoma affects approximately 400-500 newly diagnosed US patients annually, creating a small addressable market that may not support standalone profitability without label expansion
Procedural adoption barriers - PHP requires specialized interventional radiology skills and infrastructure not available at all cancer centers, limiting geographic penetration
Regulatory risk for label expansion - Future growth depends on clinical trial success and FDA approval for additional liver cancer indications with significantly larger patient populations
Systemic therapy advances - Checkpoint inhibitors (Opdivo, Keytruda) and targeted therapies continue evolving for uveal melanoma, potentially offering less invasive alternatives that could limit PHP adoption
Alternative locoregional therapies - Radioembolization (Y90), chemoembolization (TACE), and ablation techniques compete for liver-directed treatment market share
Biosimilar and generic competition post-exclusivity - After orphan drug exclusivity expires in August 2030, generic melphalan formulations could enter if competitors develop alternative delivery systems
Cash burn and dilution risk - With negative operating cash flow of approximately $13M annually and current ratio of 15.06 suggesting adequate near-term liquidity, the company will likely require additional capital raises within 12-24 months, creating dilution risk for existing shareholders
Revenue concentration risk - Single-product company with no diversification; commercial failure of HEPZATO would eliminate the investment thesis
Manufacturing and supply chain risk - Reliance on third-party manufacturers for specialized catheter components and melphalan drug substance creates potential supply disruption vulnerabilities
