Study Overview
Brief Summary
Hsp90 inhibitor AUY922 and erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. This phase I/II trial is studying the side effects and best dose of Hsp90 inhibitor AUY922 when given together with erlotinib hydrochloride and to see how well it works in treating patients with stage IIIB-IV non-small cell lung cancer.
Detailed Description
This is a phase I, dose-escalation study of Hsp90 inhibitor AUY922 followed by a phase II study. Patients receive Hsp90 inhibitor AUY922 IV over 1 hour once weekly and oral erlotinib hydrochloride once daily. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up periodically.

Outcomes
Primary Outcomes
Maximally Tolerated Dose (MTD) of AUY922 and Erlotinib Treatment Combination (Phase I)
Time Frame: During the first 4 weeks of treatment for each patient.
To determine the maximally tolerated dose (MTD), and recommended phase II dose of AUY922 when given in combination with erlotinib for patients with acquired resistance to erlotinib. (Phase I) Escalation of dose will be in a 3+3 design. If no dose limiting toxicities (DLTs) are seen in 3 patients enrolled at that dose level, then dose will be escalated to the next dose level and the next 3 patients will be enrolled at that dose. Alternatively, if 1 DLT is seen in 3 patients at that dose level, 3 more patients will be added at that same dose level. If 1 DLT is seen in 6 patients at that dose level, MTD will be determined to be at that dose. If more than 1 DLT is seen at that dose level, then the prior lower dose level will be the considered the MTD. DLT is defined as any of the following related to the investigational agent: Death and grade 3 and 4 specific hematological and non-hematological toxicities defined in the protocol.
Overall Response Rate (ORR), Defined as Complete Response(CR) + Partial Response (PR) Using the Modified RECIST 1.1 Criteria for All Patients Treated at Dose of 70mg/m2 AUG922
Time Frame: At 8 weeks from treatment initiation
Overall response rate (ORR) will be measured per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by CT scan or MRI: Complete response (CR) defined as disappearance of all target lesions. Partial Response (PR), defined as \>=30% decrease in the sum of the longest diameter of target lesions. Stable Disease (SD) defined as neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum diameters while on study. Progressive Disease (PD) defined as having at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of one or more new lesions
