This study looked at how effective the study drug (tepotinib) was at stopping the growth and spread of lung cancer. This study also measures a number of other things including safety of the study drug and the side effects, how body processes the study drug, or how the study drug affects your quality of life. The study also has an optional pharmacogenetic research part. Pharmacogenetic research is an important way to try to understand the role of genetics in human disease and how genes impact the effectiveness of drugs, because differences in genes can change the way a person responds to a particular drug.

The study included 3 cohorts with one primary endpoint (Objective Response Rate). Enrollment number and completion data is changed by new cohorts.

We are committed to enhancing public health through responsible sharing of clinical trial data. Following approval of a new product or a new indication for an approved product in both the US and European Union, the study sponsor and/or its affiliated companies will share study protocols, anonymized patient data and study level data, and redacted clinical study reports with qualified scientific and medical researchers, upon request, as necessary for conducting legitimate research. Further information on how to request data can be found on our website bit.ly/IPD21

Within six months after the approval of a new product or a new indication for an approved product in both the United States and the European Union

Qualified scientific and medical researchers can request the data. Such requests must be submitted in writing to the company's portal and will be internally reviewed regarding criteria for researchers' qualification and legitimacy of the research proposal.
