The primary endpoint is the rate of patients with tumors harboring a low level of genomic alteration (mutation, amplification or deletion) in genes (i.e. mutation, amplification, deletion) identified as causally implicated in cancer. A low level of genomic alteration is defined by the presence of less than the 5th quantile of genomic alterations to be expected in the given tumor type. Conversely, a high level of genomic alteration is defined by the presence of more than the 5th quantile of genomic alterations to be expected in the given tumor type.
