Prothena Q2 Revenue Drops 97%

Prothena (NASDAQ:PRTA), a biotechnology company focused on developing therapies for neurodegenerative diseases, released its second quarter 2025 results on August 4, 2025.

The quarter was shaped by the discontinuation of the birtamimab program, a restructuring charge of $32.6 million, and the absence of significant collaboration revenue that boosted results in the prior year.
