Ultragenyx Pharmaceutical Shareholder Alert

Overview
Ultragenyx Pharmaceutical Inc. is currently the subject of a class action lawsuit that calls attention to significant losses experienced by shareholders. ClaimsFiler, a free service providing information to investors, has announced that individuals who incurred losses exceeding $100,000 from buying shares of Ultragenyx within a specified timeframe can file lead plaintiff applications until April 6, 2026.

Details of the Case
This lawsuit targets Ultragenyx and its executives, who are accused of not disclosing critical information during the defined class period, which spans from August 3, 2023, to December 26, 2025. The allegations contend violations of federal securities laws, focusing on the company's failure to communicate the potential risks tied to their drug trial outcomes.

On December 26, 2025, the company released disappointing results from its Phase 3 studies on setrusumab (UX143), intended to treat Osteogenesis Imperfecta. These results indicated that the trials did not produce statistically significant reductions in annualized fracture rates, leading to a swift and steep decline in stock value. Following this announcement, Ultragenyx shares plummeted approximately 42%, shifting from $34.19 to $19.72 within just a few days.
