Binary regulatory risk - BLA approval failure would be catastrophic given single-platform dependency and limited pipeline diversity
Reimbursement uncertainty - even with FDA approval, CMS and private payer coverage decisions will determine commercial viability and pricing power
Manufacturing complexity and scale-up risk - biofabrication process requires 6-8 week production cycles with quality control challenges
Long-term safety data requirements may extend commercialization timeline beyond current cash runway
Synthetic graft manufacturers (Gore-Tex, Dacron) have established relationships and lower costs despite inferior clinical profiles
Other tissue-engineered vascular graft developers including university research programs and well-funded competitors
Alternative AV access technologies including catheter-based solutions that avoid surgical implantation
Severe liquidity risk - current cash position supports operations into late 2026/early 2027 based on burn rate, requiring near-term financing
Dilution risk from equity raises at depressed valuations given 71% stock decline over past year
Negative equity position and negative book value create accounting complexities and limit debt financing options
No revenue generation to offset cash burn creates binary outcome dependency on clinical/regulatory success
