GC Biopharma Corp ( Green Cross Corporation )

Brief Summary:
The purpose of the study is to assess the safety and tolerability of GC1118 in combination with irinotecan or FOLFIRI in order to determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D)

Condition or disease Intervention/treatment Phase
Metastatic Colorectal Cancer Solid Tumor Drug: irinotecan Drug: FOLFIRI Phase 1 Phase 2

Detailed Description:

A Phse 1b/2a, dose-finding, open-label, prospective study

This study consists of the Phase 1b part designed to determine the MTD and RP2D of GC1118 when administered in combination with irinotecan or FOLFIRI to patients with recurrent metastatic solid tumors and the Phase 2a part designed to assess the efficacy of GC1118 in combination with FOLFIRI as second-line therapy for recurrent/metastatic colorectal cancer
