Bacillus Calmette-Guérin (BCG)-based intravesical immunotherapy has been applied as gold standard treatment for high-risk non-muscle invasive bladder cancer (NMIBC) for almost half a century. However, several patients with high-risk disease experience relapse, including those whose condition has worsened and who failed to respond to BCG. Non-significant therapeutic options have been developed for these at-risk patients, for many years. Immunotherapies have shown promising outcomes for bladder cancer treatment. Accordingly, our research group developed the OncoTherad® (MRB-CFI-1) immunotherapy, which has shown positive outcomes in NMIBC treatment. The aim of the current study is to describe, in details, the physicochemical features and potential action mechanisms of OncoTherad® nano-immunotherapy, based on toll-like receptor 4 (TLR4)-mediated interferon and on RANK/RANKL signaling pathways, in animal model with NMIBC. Based on the current findings, OncoTherad® nano-immunotherapy did not have genotoxic effect on the investigated model and did not show signs of limiting local and/or systemic toxicity at therapeutic doses. OncoTherad® nano-immunotherapy was more effective than the BCG treatment, since it reduced by 70% the malignancy rate. Furthermore, it was possible identifying an important action mechanism of OncoTherad®, which was based on the modulation of TLR4-mediated interferon and RANK/RANKL signaling pathways that, altogether, were essential to reduce malignancy rate. OncoTherad® mechanisms in these pathways helped preventing tumor recurrence. |
