Current clinical trials and patent update on lung cancer: a retrospective review

Several clinical trials using different interventions are currently being sponsored to combat lung cancer at its different stages. The purpose of this study was to provide a portfolio of those trials. All active, open and recruiting clinical trials registered at ClinicalTrials.gov up to March 2018 were included. Information related to 6092 registered lung cancer trials was downloaded. Phase II trials were in the majority, comprising nearly 48.7% of total clinical trials with industry the major sponsor (41.3%) followed by NIH (12.3%). Multicenter studies were the norm accounting for 47.9% and the main study location was the USA (50.9%). Common interventions were radiation (26%), surgery (22%) and EGFR inhibitors (17%). Patent information includes major patent filing office and sponsors. The data analysis provides a comprehensive description of lung cancer trials.
