AP-01 is LNP-formulated composite siRNAs that work in concert to downregulate the expression of a cancer-specific transcript of the gene encoding MIR-1, a master regulator of invadopodia biogenesis and Wnt signaling in cancer cells. AP-01 is designed to simultaneously block the invasive growth and the distant metastasis of advanced cancers. Antapodia Nanotherapeutics leverages state-of-the-art and tissue-customized LNP technologies to target both liver and non-liver cancers. The company has completed more than 10 compelling POM/POC studies showing that systemic administration of AP-01 is able to shrink primary tumors and abolish distant metastasis and significantly lengthens survival in various models of TNBC, PDAC, and NSCLC (Figures 1-4). Intratumoral (IT) administration of AP-01 also leads to remarkable tumor shrinkage in orthotopic TNBC and HCC modes wherein loco-regional therapies are clinically applicable (Figures 5-7). The company is now testing AP-01 in PDX tumor metastasis models and optimizing its dosing schedule to further substantiate its anti-tumor efficacy and survival-lengthening effect.

TNBC: triple-negative breast cancer; PDAC: pancreatic ductal adenocarcinoma; NSCLC: non-small cell lung cancer; HCC: hepatocellular carcinoma; PDX: patient-derived xenograft.
