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."

On October 8, 2025 Oncoinvent reported new data highlight continued potential of Radspherin to prevent disease progression Oncoinvent ASA, a clinical-stage radiopharmaceutical company developing innovative treatments for solid cancers, announced positive final 24-month follow-up results from its Phase 1 clinical trial (RAD-18-001) evaluating Radspherin in patients with platinum-sensitive recurrent ovarian cancer and peritoneal carcinomatosis (Press release, Oncoinvent, OCT 8, 2025, https://www.oncoinvent.com/press-release/oncoinvent-reports-positive-final-data-from-phase-1-trial-of-radspherin-to-treat-ovarian-cancer/?utm_source=mailpoet&utm_medium=email&utm_source_platform=mailpoet [SID1234656487]). Radspherin, direct intraperitoneal targeting with the alpha-emitter radium-224, aims to eliminate post-surgery micro-metastases and thereby prevent or delay peritoneal recurrence.

In this Phase 1 trial, 10 out of 21 patients received the highest and recommended intraperitoneal dose of 7 MBq Radspherin after dose escalation (1, 2, 4 and 7 MBq). The final 24-month data still reports that only 1 of these 10 patients had peritoneal recurrence, and peritoneal recurrence rate remains at 10%. Two additional patients were reported with lymph node metastases outside of the peritoneum, giving an overall recurrence rate of 30%. In similar populations, approximately 55-60% of patients receiving best standard of care would expect disease recurrence at this time point[1],[2],[3].

"These highly encouraging results conclude our Phase 1 program for Radspherin and fuel our determination to advance Radspherin as an innovative treatment for patients with peritoneal metastases as quickly as possible," said Oystein Soug, CEO of Oncoinvent. "We are profoundly grateful to the patients, investigators, and the team for their invaluable contributions and look forward to interim results from our Phase 2 study next year."

"Peritoneal metastases remain a defining challenge in ovarian cancer, often driving recurrence," said Dr. Luis Chiva, Principal Investigator and Director of Department of Obstetrics and Gynecology, Clinica Universidad de Navarra, Spain. "These final results are truly encouraging, suggesting that Radspherin could help delay disease progression and offer patients hope for longer, healthier lives. It is particularly promising to see that the new recurrences were limited to lymph nodes, which are typically associated with longer survival compared to peritoneal relapses.

About RAD-18-001

RAD-18-001 was an open label Phase 1 trial conducted in patients with peritoneal metastases in platinum-sensitive recurrent ovarian cancer. The trial was designed to evaluate dosing, safety and tolerability, and signal of efficacy of intraperitoneally administered Radspherin following complete surgical resection. A total of 21 patients were enrolled across sites in Norway, Belgium and Spain.

The publication, titled "CD40 agonist mitazalimab with mFOLFIRINOX in untreated metastatic pancreatic cancer: biomarkers associated with outcomes from OPTIMIZE-1", provides mechanistic insights into determinants of clinical response and offers translational support for a planned randomized Phase 3 trial.

Key findings from the publication include:

Clinical efficacy: The OPTIMIZE-1 study met its primary endpoint, with a confirmed objective response rate of 42.1% in the Phase 2 cohort. Median duration of response was 12.6 months, progression-free survival 7.7 months, and overall survival 14.9 months. The survival rate at 24 months was 29.4%, triple that of chemotherapy alone.
Tumor gene signature linked to outcome: Baseline expression of a tumor-intrinsic fibrotic gene signature, directly linked to the mode of action of mitazalimab, was associated with improved overall survival.
Peripheral immune activation: Mitazalimab-induced increases in circulating activated immune cells correlated with better clinical outcomes.
Intratumoral immune activation: Patients with objective clinical responses displayed mitazalimab-induced immune activation supporting mitazalimab’s contribution to clinical outcomes
Translational impact: strongly supports mitazalimabs contribution to the improved clinical outcomes observed in OPTIMIZE-1 and supports future development of predictive biomarkers for mitazalimab.
"These data provide important guidance for understanding which patients may benefit most from mitazalimab-based immunotherapy in pancreatic cancer, and provides further evidence for mitazalimab’s contribution to the sustained clinical benefit observed in the OPTIMIZE-1 trial" said Søren Bregenholt, CEO of Alligator Bioscience. "The integration of biomarker-driven insights into our clinical development strategy strengthens the foundation for the next phase of mitazalimab’s evaluation in this high-need indication."
