A Study to Evaluate the Impact of Management Strategies on Gastrointestinal-Related Adverse Events in Participants With Non-Small Cell Lung Cancer Harboring Epidermal Growth Factor Receptor (EGFR) Exon 20 Insertion Mutations Receiving TAK-788

The purpose of the study is to characterize the incidence and severity of TAK-788-associated diarrhea in previously treated participants with locally advanced or metastatic non-small-cell lung cancer (NSCLC) whose tumors harbor EGFR exon 20 insertion mutations treated with TAK-788 when administered with or without intensive loperamide prophylaxis.
