Mechanism of Action

Targets/IC₅₀/Ki	Raf ^[1]
In vitro	Tovorafenib (MLN2480) inhibits MAPK pathway signaling in BRAF mutant and some RAS mutant preclinical cancer models at concentrations that are tolerated in vivo^[1]. It is found to activate phosphorylated MEK at very low concentrations, but inhibits this same activity at higher concentrations. The inhibitory effects of this compound are found to vary across models and genetic contexts^[2]. In vitro analysis of the drug combination of MLN2480 and TAK-733 (an investigational allosteric MEK kinase inhibitor) in cell proliferation assays demonstrates synergistic activity. In addition, western blot analysis demonstrates the effect of it in reversing feedback activation of MEK in response to TAK-733, leading to more concerted MAPK pathway inhibition. It only modestly inhibits PRAK^[1]^[2].
In vivo	In vivo, Tovorafenib (MLN2480) shows antitumor activity in melanoma, colon, lung, and pancreatic cancer xenograft models^[3]. This compound (37.5 mg/kg) is well tolerated in a tumor xenograft model. The combination of it (12.5 mg) and TAK-733 (1 mg/kg) is effective in an SK-MEL-30 xenograft model, but monotherapy with either compound produces negligible effects^[2].
