The purpose of this study is to determine the Maximum Tolerated Dose and the Dose-Limiting Toxicity of the drug to further evaluate safety and antitumor activity.
Name: PR610
Description: Dose escalation of PR610 to determine maximum tolerated dose for weekly administrationType: DrugPR610
Description: The first cohort of three subjects will receive PR610 at Dose Level 1. Subsequent cohorts will receive PR610 at a dose levels determined as per dose escalation criteria. The MTD will be defined as the dose level at which one (1) or fewer subject in six exhibit DLT with the next highest dose level demonstrating two (2) or more of six (6) subjects with DLT (or for which more than ≥33% of subjects exhibit DLT if the cohort size exceeds 6 subjects).
Measure: Determine the Maximum Tolerated Dose (MTD) of PR610 for Both a 1-hour and a 24-hour Weekly IV Infusion Time: 3 weeks (1 cycle)Description: DLT is defined as the following: Occurs during the first cycle of PR610 Is considered PR610-related, as defined by "Definitely-related", "Probably-related" or "Possibly-related" Is clinically significant, as determined by the Principal Investigator In addition, DLT will meet at least one of the criteria listed below using grading criteria from the CTCAEv4. Grade 4 hematologic toxicity Any drug-related toxicity that prevents administration of 100% of all doses of PR610 planned for Cycle 1 Grade 3 or higher non-hematologic toxicity
Measure: Determine the Dose-Limiting Toxicity (DLT) of PR610 for Both a 1-hour and a 24-hour Weekly IV Infusion Time: 3 weeks (1 Cycle)Description: The number of adverse events experienced by participants will be measured.
Measure: Evaluate the safety profile of PR610: Adverse Events Time: 30 days following the last administration of study treatmentDescription: Efficacy will be determined for each subject that received at least one dose of PR610 and had at least one post-baseline disease assessment. The following four outcomes will be tabulated: Tumor response Time to response Duration of response Progression-free survival
Measure: Evaluate the activity of PR610 in a general phase I population and in a subset of subjects with NSCLC genetically resistant to reversible EGFR inhibitors Time: 30 days following the last administration of study treatmentSingle Group Assignment
