The combination of immunotherapy and mutant p53 degraders may have some promise. Dr. Joaquina C. Baranda. P53 acts as a guardian of the DNA by acting as a checkpoint in the cell cycle process ( 4 ). A team of investigators led by Dr. Baranda is currently testing the efficacy of atorvastatin in p53-mutant and p53 wild-type malignancies in the scope of a window-of-opportunity trial.13 The aim of the trial is to investigate whether atorvastatin, given at a dose of 80 mg/day for 1 to 4 weeks, can reduce the concentration of mutated p53 in tumor tissues.13 The study's goal is to enroll patients harboring 10 to 12 specific, conformational mutations in the p53 gene, which have previously been shown to be susceptible to atorvastatin in preclinical experiments.
