Crizotinib and entrectinib are both active against ROS1+ non-small cell lung cancer. But which is best? The answer seems easy: Just compare the drugs' clinical trial results. However, not all trials are created equal, and these differences in trial designs can lead to irrelevant comparisons—like comparing athletes' running times without noting that one ran a kilometer while the other ran a mile. Now results from an innovative, "virtual" clinical trial presented at the American Society for Clinical Oncology (ASCO) Annual Meeting 2019 attempt to place crizotinib and entrectinib on an equal playing field. In this analysis, patients taking entrectinib were able to stay on treatment longer and had about almost 6 months longer progression-free survival than patients treated with crizotinib.
