Measure
Erlotinib Responsive
Participants self-administered entinostat in combination with continued erlotinib self-administration. "Erlotinib-responsive" participants are those who progressed following either a complete or partial response to erlotinib or a period of stable disease lasting at least 3 months.
Erlotinib Nonresponsive
Participants self-administered entinostat in combination with continued erlotinib self-administration. "Erlotinib-nonresponsive" participants are those who either progressed immediately during treatment with erlotinib (that is, after at least 1 full cycle of erlotinib treatment) or had an objective response or period of stable disease lasting less than 3 months.
