A Study to Assess Disease Activity and Adverse Events of Intravenous (IV) Telisotuzumab Vedotin Compared to IV Docetaxel in Adult Participants With Previously Treated Non-Squamous Non-Small Cell Lung Cancer (NSCLC)

Cancer is a condition where cells in a specific part of body grow and reproduce uncontrollably. Non-small cell lung cancer (NSCLC) is a solid tumor, a disease in which cancer cells form in the tissues of the lung. The purpose of this study is to determine if telisotuzumab vedotin works better than docetaxel and to assess how safe telisotuzumab vedotin is in adult participants with NSCLC who have previously been treated. Change in disease activity and adverse events will be assessed. Telisotuzumab vedotin is an investigational drug being developed for the treatment of NSCLC. Participants will be randomly assigned a treatment of telisotuzumab vedotin or docetaxel at an 1:1 ratio. Each group receives intravenous (IV) infusion of telisotuzumab vedotin or IV infusion of docetaxel. Approximately 768 adult participants with c-Met overexpressing NSCLC will be enrolled in the study in approximately 330 sites worldwide. Participants will receive IV telisotuzumab vedotin every 2 weeks or docetaxel every 3 weeks until meeting study drug discontinuation criteria. At the conclusion of the study, participants who continue to demonstrate clinical benefit may be eligible to receive study treatment via an extension of the study, a rollover study, or through another mechanism. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
