Oncotelic Therapeutics, Inc. announced that its joint venture Sapu Nano has identified a High-RICTOR/Low-RPTOR molecular signature that predicts tumor sensitivity to Sapu003, the company's intravenous Deciparticle formulation of everolimus. This biomarker framework, based on analysis of more than 9,000 tumor samples across 20 cancer types, represents the first prospective selection strategy for IV everolimus and will be presented at the 2025 San Antonio Breast Cancer Symposium.
Data show that mTORC2-dominant tumors exhibit heightened mTOR dependency and predicted sensitivity to Sapu003. These tumors include HR+/HER2- breast cancer, lung adenocarcinoma, gastric cancer, renal cancer, ovarian cancer, acute myeloid leukemia, and T-cell malignancies. The identification of this biomarker signature could enable clinicians to select patients most likely to benefit from the treatment, potentially improving outcomes while reducing unnecessary exposure to therapy for those unlikely to respond.
Sapu003 overcomes limitations of oral everolimus through higher tissue penetration, reduced gastrointestinal accumulation, and preserved metabolic specificity. The intravenous formulation represents a significant advancement in mTOR inhibitor delivery, addressing challenges that have limited the effectiveness of oral formulations in certain cancer types. The biomarker discovery comes from extensive genomic analysis available through resources like the company's research portal, which provides access to comprehensive tumor data.
The identification of this predictive biomarker has important implications for precision oncology, potentially enabling more targeted use of mTOR inhibitors in cancer treatment. By identifying which patients are most likely to respond to Sapu003, clinicians could optimize treatment strategies and improve therapeutic outcomes. This approach aligns with the broader trend in oncology toward personalized medicine, where treatments are selected based on individual tumor characteristics rather than a one-size-fits-all approach.
The research represents a significant step forward in understanding mTOR pathway biology and its role in cancer progression. mTORC2-dominant tumors appear to have distinct molecular characteristics that make them particularly vulnerable to targeted mTOR inhibition. This discovery could lead to more effective treatment strategies for several cancer types that currently have limited therapeutic options, particularly those identified as having the High-RICTOR/Low-RPTOR signature.
As the research moves toward clinical application, the biomarker framework could help streamline clinical trial design by enabling more precise patient selection. This could accelerate the development of Sapu003 and potentially improve success rates in clinical testing. The findings also contribute to the growing body of knowledge about mTOR signaling in cancer, which could inform the development of additional targeted therapies for mTOR-dependent tumors.
