A Phase 2 Study of TH-4000 (Tarloxotinib) in Patients With EGFR-Mutant, T790M-Negative, Advanced Non-Small Cell Lung Cancer Progressing on an EGFR Tyrosine Kinase Inhibitor


Brief Summary
This phase 2 study is designed to evaluate the safety and activity of TH-4000 (Tarloxotinib), a hypoxia-activated prodrug, in patients with EGFR-Mutant, T790M-Negative, Advanced non-small cell lung cancer (NSCLC).

Detailed Description
A single arm open label multi-center Phase 2 study in which the pharmacokinetics, safety, tolerability and efficacy of TH-4000 (Tarloxotinib) will be assessed in patients with EGFR mutant, T790M negative advanced NSCLC. Patients must have demonstrated progression during EGFR TKI therapy. Hypoxia PET scans will be obtained in select centers to analyze potential predictors of tumor response.


Phase 2 - takes the treatment one step further, assessing the activity of a particular therapy in a disease, often building upon leads from the Phase I trial. While patients are generally required to be previously untreated, participation in a Phase II trial doesn't usually preclude the patient from getting the standard treatment after they've received the investigational agent. At best they are allowed to get a new drug they wouldn't be able to get otherwise that may turn out to be better for their disease.

Inclusion and Exclusion Criteria
