It is still controversial whether comprehensive genome screening of target
molecules by next generation sequencing (NGS) is needed to increase clinical
efficacy of investigational drugs or accelerate drug development, although
several studies are being carried out. Therefore, we performed a prospective
study to evaluate the feasibility of comprehensive gene screening in this
setting. Our findings indicate that actionable alterations were identified in 45%
of the analyzed patients, most frequently in those with breast cancer. Common
actionable alterations were found in PIK3CA mutation, BRCA2 mutation, ERBB2
amplification, and CCND1 amplification. In total, 22% of the analyzed patients
could be entered into phase I clinical trials, and 8% of them were treated with
"matched" drugs. Among patients who received matched therapies, response and
disease control rates were 33 and 78%, respectively. On the other hand, in the
patients who received "non-matched" therapy, the objective response rate was 6%.
We believe this data indicates that NGS-based molecular pre-screening is a potent
platform for use before patient entry into phase I trials.
