Sapu Nano Unveils First-in-Human Clinical Trial of Sapu-003 at 8th Australian Translational Breast Cancer Research Symposium

Using Sapu Nano’s proprietary Deciparticle™ technology, Sapu-003 delivers everolimus intravenously

SYDNEY, Australia, Oct. 08, 2025 (GLOBE NEWSWIRE) -- via IBN – Sapu Nano today announced the presentation of its poster, “Sapu-003: Novel Intravenous Deciparticle™ Everolimus Entering Phase 1 Study in Australia,” at the 8th Australian Translational Breast Cancer Research Symposium (ATBCR 2025). Sapu Nano is part of the Sapu family of companies, formed through GMP Biotechnology Limited, a joint venture between Oncotelic Therapeutics, Inc. (OTCQB: OTLC) and Dragon Overseas Capital Limited.

Sapu-003 is the first intravenous (IV) Deciparticle™ formulation of everolimus, an mTOR inhibitor widely used in oncology. While oral everolimus (Afinitor®) has demonstrated efficacy in breast cancer, renal cell carcinoma, and neuroendocrine tumors, its broader use has been constrained by low bioavailability, variable systemic exposure, and gastrointestinal toxicities.

Global Development Partnership
The trial is being conducted in collaboration with SOCRU, a leading Phase 1 clinical unit in Australia; Ingenū, a clinical research organization with deep early-phase expertise; and Medicilon, Sapu Nano’s strategic partner for preclinical drug development. Together, these partnerships ensure robust clinical execution, regulatory alignment, and high-quality product supply for the study.

Call to Patients and Physicians
The trial (ACTRN12625001083482) is now open for enrollment at leading oncology centers across Australia. Eligible participants include adults with advanced HR+/HER2– breast cancer or other mTOR-sensitive tumors who have exhausted standard therapies. Physicians are encouraged to refer patients who may benefit from participation.

“Sapu-003 represents a significant advance in the delivery of mTOR-targeted therapies,” said Vuong Trieu, PhD, Chief Executive Officer of Sapu Nano. “Through the combined expertise of SOCRU, Ingenū, and Medicilon, we are positioned to accelerate development and bring this next-generation treatment option to patients with advanced cancers.”
