Lipid nanoparticle (LNP)-formulated small interfering RNA (siRNA) has recently emerged as efficient and clinically proven approaches in the molecular targeting of disease-driver genes. LNP-formulated siRNA therapy has multiple advantages over traditional therapeutics in cancer therapy (Table 1). For instance, the parenteral administrations of an LNP-encapsulated siRNA specific for transthyretin (TTR) reduce up to 86.8% of transthyretin produced by the liver in patients with hereditary transthyretin-mediated amyloidosis and thus became the first clinically approved siRNA therapy. Antapodia Therapeutics harnesses the third-generation highly biodegradable LNPs in conjunction with a novel "liver-blocking" technology to efficiently deliver invadopodia-targeted siRNA to non-hepatic cancers, resulting in tremendous anti-tumor and anti-metastasis efficacies in preclinical studies. In collaboration with academic and industrial leaders in LNPs, the company strives to develop the best-in-class cancer-gene therapies to concur aggressive and metastatic cancers.
