About this study

There is a huge variety of nucleotide substitutions that activate RAS. The search for new "universal" drugs for the RAS pathway that either interfere with RAS upregulation upstream in the signaling pathway or offset the consequences of RAS activation is important for improving therapeutic outcomes for patients with refractory malignancies. The use of leflunomide or the combination of MEK inhibitor + hydroxychloroquine ± bevacizumab is promising for patients with mutations in RAS cascade genes who have failed all existing treatment standards.
