Study Timeline: The study began on November 9, 2020, with the last update submitted on October 16, 2025. These dates are crucial as they indicate the study’s ongoing nature and the commitment to updating and refining the data collected over time.

Market Implications: The ongoing study by Ultragenyx could positively influence the company’s stock performance by reinforcing its commitment to addressing rare diseases. This might boost investor confidence, especially as the study progresses and yields valuable data. In the broader industry context, the study highlights the competitive landscape of rare disease treatment, where timely and effective monitoring programs can set companies apart.

The study is currently recruiting, with further details available on the ClinicalTrials portal.
