Study Summary

Phase 1A/B, multicenter, open-label, non-randomized, dose-escalation oncology study to evaluate the administration of EC1456 in advanced solid tumors. In part A, EC1456 will be dose escalated on 4 concurrently enrolling schedules. FR-positive expression on a 99mTc-etarfolatide scan is not required for inclusion in Part A. Part B of the study will confirm the maximum tolerated dose (MTD) and the recommended Phase 2 (RP2) dose of EC1456, and evaluate the efficacy of EC1456 in NSCLC all subtype patient populations with FR-positive cancer in up to three schedules (i.e., twice weekly, once weekly, and four times weekly). FR-positive expression on a 99mTc-etarfolatide scan is required for inclusion in Part B. Minimum length of patient participation is anticipated to be 10 weeks (two 3-week cycles followed by a 30 day follow-up period).

Primary Outcome

Part A - To dose escalate EC1456 dose until maximum tolerated dose (MTD) and recommended Phase 2 (RP2) dose for multiple schedules is reached. -All patients who receive at least one dose of EC1456 will be evaluated for safety. All AEs and SAEs will be graded as per CTCAE V4.0. For each dose level, summaries of dose adjustments, adverse event rates, laboratory changes, cumulative toxicity, and dose limiting toxicity (DLT) will be analyzed. Summaries of CTCAE grades will be analyzed at each dose
