1.Primary Outcome
Title Overall Response Rate (ORR)
Hide Description Overall response rate (ORR) was assessed as the number of patients who achieve either a partial (PR) or complete response (CR) measured by CT scans and Response Evaluation Criteria In Solid Tumors (RECIST 1.1) criteria, divided by the total number of patients treated on the study. CR: Disappearance of all target lesions, all non-target lesions, and no new lesion. PR: At least a 30% decrease in the sum of diameters of target lesions, no progression in non-target lesion, and no new lesion.
Time Frame 6 weeks
Hide Outcome Measure Data
Hide Analysis Population Description

Term from vocabulary, CTCAE (4.0)
This study had to be terminated early because patients with small cell lung cancer were not able to tolerate clinically relevant doses of desipramine, and no clinical activity was observed in the first enrolled patients.
