What was measured

The dose dependent change in a mitogen-activated protein kinases (MAPK) pathway expression signature was analyzed for all available samples of MTC and NSCLC participants. Participants with archived sample (used as baseline) and on treatment Cycle 2 Day 1 (1 cycle = 28 days) tumor tissues with greater than 20% tumor cells are included in the analysis. The changes in tumor biomarker DUSP6 levels was explored.

Analysis population: Safety Population included all participants who have received at least 1 dose of the study drug regardless of starting dose levels.
