Financial Highlights

Full Year 2025 Financial Results

For the year ended June 30, 2025, the Company reported total expenses of $41.8 million compared to $22.5 million for the year ended June 30, 2024. Royalties and license fees were $0 in 2025, compared to $(108,000) in 2024, which reflected the reversal of a prior accrual. Research and development expenses were $18.3 million in 2025, up from $15.6 million in 2024, and were primarily related to the ongoing clinical development of BB-301 for the treatment of OPMD. The increase in research and development expenses reflected the timing of contract manufacturing activities and payments associated with the OPMD Natural History and Dosing study.

General and administrative expenses totaled $23.4 million in 2025 compared to $7.0 million in 2024. The increase was primarily driven by higher share-based compensation of $14.5 million, as well as increases in legal fees of $492,000, consulting fees of $605,000, travel expenses of $219,000, and salaries and wages of $685,000.

The loss from operations for the year ended June 30, 2025, was $37.9 million compared to $21.8 million for the prior year.

About BB-301

BB-301 is a novel, modified AAV9 capsid expressing a unique, single bifunctional construct promoting co-expression of both codon-optimized Poly-A Binding Protein Nuclear-1 (PABPN1) and two small inhibitory RNAs (siRNAs) against mutant PABPN1 (the causative gene for OPMD). The two siRNAs are modeled into microRNA backbones to silence expression of faulty mutant PABPN1, while allowing expression of the codon-optimized PABPN1 to replace the mutant with a functional version of the protein. We believe the silence and replace mechanism of BB-301 is uniquely positioned for the treatment of OPMD by halting mutant expression while providing a functional replacement protein.
