Rezolute reported positive interim data from its Phase 3 upLIFT study of ersodetug in tumor hyperinsulinism. Of the 8 participants enrolled so far (50% of the planned 16), 6 met the primary endpoint of at least a 50% reduction in IV glucose requirements. All 6 responders also achieved complete discontinuation of intravenous glucose. One participant withdrew due to cancer progression and is counted as a non-responder; the 8th is still dosing.
