Rhea-AI Summary

Quince Therapeutics (QNCX) filed an 8-K under Regulation FD to correct an Investor Day statement. The company removed Slide 57 and the related video from its October 2, 2025 Virtual Investor Day and advised investors not to rely on the slide’s claim that IntraBio’s N-acetyl-L-leucine (NALL) “failed Phase 2 A-T study across all endpoints.”

Quince clarified its statement drew from a European Journal of Paediatric Neurology article describing a single-site study in ataxia-telangiectasia, which reported no significant improvements in ataxia symptoms or motor function, and was not the multi-site IntraBio Phase 2 Study.
