Here, we studied Fluvastatin (Fluva) and Zoledronate (Zol), representative molecules of each class, respectively. In vivo metastatic potentials of both molecules were assessed. For the first time, we observed a significant reduction of established metastasis progression under Fluva treatment. Treatment with Zol at 100 μg/kg and Fluva at 15 mg/kg both inhibited 80% of metastasis bioluminescence signal and increased mice survival. The Zol and Fluva transcriptomic profiles of MDA-MB-231 treated cells, revealed analogous patterns of affected genes but each of them reached with different kinetics. The observable changes in gene expression started after 24 for Fluva IC5072h and only after 48h for Zol IC5072h. To obtain early changes in gene expression of Zol treated cells, three times higher dose of Zol IC5072h, had to be applied. Combining Fluva and Zol in vivo showed no synergy but a several days benefit in mice survival. This study demonstrated that Zol or Fluva are of potential clinical use for the treatment of established
