Description
InformationRuxotemitide (LTX 315) Ruxotemitide (LTX 315, Oncopore) is the oncolytic peptide that kills cancer cells through Bax/Bak-regulated mitochondrial membrane permeabilization.In vitroLTX-315 is highly active against both murine and human melanoma cell lines in vitro. while displaying low EC50 cytotoxic activity against human red blood cells.LTX-315 has been shown to induce the release of ATP and HMGB1 both being DAMPs involved in ICD.In vivowhen syngeneic B16 melanomas are treated intralesionally, a majority of the animals (~80%) treated with LTX-315 experience a complete and long-lasting tumor regression. LTX-315 injection induces an extensive hemorrhagic necrosis of the tumor parenchyma and a massive infiltration of CD3+ T cells, indicating that the peptide induces a type of cell death that leads to an increase in the number of tumor-infiltrating lymphocytes (TILs). treatment of a single tumor with LTX-315 generates a systemic anti-tumor immune response that eradicated distant lesions and prevented reoccurrence following tumor rechallenge
