Clinical Trial Summary

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.

Description:

No patients were enrolled in the Phase 2 part of the study. Phase 2 endpoints were not analyzed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Dose Limiting Toxicities (DLTs)		Cycle 1 and Cycle =2 (up to 141 days)
Primary	Number of Participants With Adverse Events	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.	From first dose of study drug up to 30 days after the last dose of study (maximum study drug exposure 114 days)
Secondary	Area Under the Concentration-time Curve at 24 Hours (AUC24) for Gilteritinib		0, 0.5, 1, 2, 4, 6, 24 hours post-dose on Days 1 and 28 of cycle 1
Secondary	Maximum Concentration (Cmax) for Gilteritinib		0, 0.5, 1, 2, 4, 6, 24 hours post-dose on Days 1 and 28 of cycle 1
Secondary	Time After Dosing When Cmax Occurs (Tmax) for Gilteritinib		0, 0.5, 1, 2, 4, 6, 24 hours post-dose on Days 1 and 28 of cycle 1
Secondary	Concentration Immediately Prior to Dosing at Multiple Dosing (Ctrough) of Gilteritinib	All participants in Gilteritinib 120 mg + Erlotinib 150 mg group discontinued before cycle 3.	Predose on Day 1, 3, 8, 15, 22, 28 of cycle 1, Day 1 of cycle 3 and Day 1 of cycle 4
Secondary	AUC24 of Erlotinib		0, 0.5, 1, 2, 4, 6, 24 hours post-dose on Day 28 of cycle 1
Secondary	Cmax of Erlotinib		0, 0.5, 1, 2, 4, 6, 24 hours post-dose on Day 28 of cycle 1
Secondary	Tmax of Erlotinib		0, 0.5, 1, 2, 4, 6, 24 hours post-dose on Day 28 of cycle 1
Secondary	Ctrough of Erlotinib		Day 8, 15, 22, 28 of cycle 1
Secondary	Objective Response Rate (ORR) in Phase 1b	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.	End of treatment (approximately 4 months)
