Sapu003 is a novel Deciparticle formulation of everolimus for intravenous administration, designed to overcome the pharmacologic limitations of oral mTOR inhibitors (Afinitor), including poor bioavailability, dose-limiting toxicity, and restricted tumor penetration. Collectively, the accepted abstracts highlight the clinical rationale, molecular biomarkers, and pharmacokinetic justification supporting the ongoing Phase 1 trial of Sapu003 in hormone receptor-positive (HR )/HER2 metastatic breast cancer.

"These three accepted abstracts underscore the breadth and innovation of our Deciparticle nanomedicine platform," said Dr. Vuong Trieu, CEO of Sapu Nano. "Sapu003 represents the first intravenous everolimus formulation with the potential to deliver robust mTOR inhibition and direct tumor cytotoxicity. We are honored to share these findings with the global oncology community at SABCS."
The studies were conducted in collaboration with Southern Oncology Clinical Research Unit (SOCRU), Ingenu CRO, and Medicilon, and reflect a coordinated clinical-translational effort bridging molecular biomarker discovery, pharmacokinetic modeling, and scalable GMP manufacturing of Deciparticle everolimus.
