Randomized, open-label trial evaluating the preventive effect of tetracycline on afatinib induced-skin toxicities in non-small cell lung cancer patients.

Background: Afatinib has shown long progression free survival and improvement in quality of life in advanced Non-Small Cell Lung Cancer (NSCLC) patients. Although afatinib causes acneiform rash, it can be manageable. Tetracyclines are usually used to treat it; nonetheless, there is no trial that evaluates their prophylactic efficacy on afatinib induced-skin toxicities (AIST).
