Summary
Brief summary (as posted)
Treatment for patients with mutation in the epidermal growth factor receptor (EGFR) with specific domain tyrosine kinase inhibitors (TKIs) has given place to objective clinical response, increase in progression-free survival (PFS) compared to cytotoxic chemotherapy. However, despite clinical success with different TKIs, most patients eventually develop acquired resistance to these agents after an average period of time of 10 months. Recently metformin, an oral hypoglycemic agent, has been associated with reduction in the global risk of incidence and mortality of different types of cancer, by exercising anti-tumor properties. Its role as a chemo-preventive and adjuvant drug in overcoming acquired resistance to chemotherapy, target therapy and immunotherapy in NSCLC is still under discussion. However, preclinical data support the role as an adjuvant drug in the treatment of NSCLC in combination with chemotherapy or EGFR-TKIs. This evidence led to examine the effects of metformin in combination with EGFR-TKIs in a NSCLC cellular line panel, obtaining a different sensibility to the unique use with EGFR-TKIs. The combination of metformin and TKIs reduced the colony forming capacity and proliferation, and induced a huge pro-apoptotic effect in NSCLC cellular lines and resistance in EGFR-TKIs. This suggests that metformin may reduce the resistance to TKIs. A retrospective study in patients from our institution from 2008 to 2014, showed significant clinical benefit in patients who used metformin, improving the global survival. Based on these considerations, we propose a phase II randomized study to assess the effect and safety of metformin in combination with TKIs as second line therapy in patients with NSCLC in advanced stages with EGFR mutation. The main objective of this study is to assess the progression-free survival period in patients with advanced non-small cell lung cancer in treatment with TKIs and metformin versus TKI alone.
