The 8-K investor presentation restates that the Phase 3 TransportNPC study did not meet its primary endpoint, but a prespecified analysis showed a 71% relative slowing of disease progression (p=0.046), the NDA was submitted in October 2026, and PRV eligibility could bring non-dilutive value (recent vouchers sold for ~$200M on average). These offsetting positives and negatives leave no clear near-term direction for RFL.
