Number of Participants With Adverse EventsPrimary· From first dose of study drug up to 30 days after the last dose of study (maximum study drug exposure 114 days)
Treatment-emergent adverse events (TEAE) was defined as an adverse event (AE) that started after administration of the study drugs and occurred within 30 days of the last dose of the study drugs. If a participant experienced an event both during the preinvestigational period and during the investigational period, the event was considered a TEAE only if it worsened in severity.

Objective Response Rate (ORR) in Phase 1bSecondary· End of treatment (approximately 4 months)
ORR was defined as Objective Response Rate (ORR) was the proportion of patients whose best overall response was complete response (CR) or partial response (PR) per RECIST version 1.1. Only patients with measurable disease at baseline were to be included in the analysis of ORR.

Adverse events — posted to ClinicalTrials.gov
Time frame: From first dose of study drug up to 30 days after the last dose of study (maximum study drug exposure 114 days).
Reporting threshold: 0%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The purpose of the Phase 1b part of the study was to evaluate the safety and tolerability of ASP2215 in combination with erlotinib and determine the recommended phase 2 dose (RP2D) of ASP2215. The purpose of the Phase 2 part of the study was to evaluate the objective response rate (ORR) of the RP2D of ASP2215 in combination with erlotinib.
