Impact of Recent Study Results
On December 11, 2025, Rezolute, Inc., XOMA's development partner, publicly shared results from its Phase 3 sunRIZE study regarding the drug ersodetug. The findings indicated that the study failed to meet its primary endpoint, which was to evaluate the change in average weekly hypoglycemia events in patients with congenital hyperinsulinism.
- The study reported an approximate 45% reduction in hypoglycemia events at the highest dose of ersodetug (10 mg/kg).
- This reduction was not statistically significant when compared to a placebo group, which experienced a 40% improvement.
- Furthermore, a key secondary endpoint revealed only a 25% reduction in average daily hypoglycemia time, again not statistically significant in comparison to the placebo.
Stock Performance Following Study Announcement
Following the announcement of these mixed results, XOMA's stock experienced a notable decline, falling by $7.82 per share, which equates to a drop of 22.76%, closing at $25.39 per share on December 19, 2025. This significant stock movement raises questions surrounding investor confidence and the company's future prospects.
