• The FDA has confirmed that HS-NRE is deemed to be a surrogate biomarker reasonably likely to predict clinical benefit and could serve as a basis for accelerated approval.
• The planned BLA submission for TA-ERT in the first half of 2026 is a key milestone.
• The ongoing Phase 2 study of tildacerfont for MDD could provide valuable data.
• The company believes its current cash position is sufficient to fund operations through the end of 2025.

Negatives

• The company reported a net loss of $14.0 million for the first quarter of 2025, which is higher than the $11.6 million loss for the same period in 2024.
