The purpose of this study is to determine if Itacitinib in combination with erlotinib is safe and effective in the treatment of nonsquamous non-small cell lung cancer (NSCLC) that is Stage IIIB/Stage IV or recurrent whose tumors have EGFR activating mutations.
Description: Subjects will take erlotinib daily and begin dosing with itacitinib once daily (QD) on Cycle 1, Day 1. The safety and tolerability of the regimen will be assessed during the first 21 days of therapyMeasure: Part 1: Determination of the dose of itacitinib that is safe and tolerable in combination with erlotinib as measured by the number of dose-limiting toxicities (DLTs) observed in the evaluation cohort. Time: Baseline through Day 21
Description: PFS is defined as the time from randomization until the earliest date of disease progression determined by investigator assessment of objective radiographic disease assessments per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, or death due to any cause if sooner.Measure: Part 2: Progression-free survival (PFS) Time: Randomization to disease progression, or death due to any cause if sooner. Approximately 23 months.
Description: Objective response determined by radiographic disease assessments per RECIST (v1.1), by investigator assessmentMeasure: Part 2: Objective Response Time: Baseline through end of study. Approximately 31 months.
Description: Duration of response determined by radiographic disease assessments per RECIST (v1.1), by investigator assessment Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.Measure: Part 2: Duration of Response Time: Baseline through end of study. Approximately 31 months.
