ZD6126 is a vascular-targeting agent and a prodrug of N-acetylcolchinol, related to colchicine.[1] It has shown promising results on tumors in mice.[2]

A phase I clinical trial identified gastrointestinal and cardiac effects as limiting dosing.[3] Two phase II clinical trials were started investigating ZD6126 in metastatic renal cell carcinoma and metastatic colorectal cancer.[4][5]

ZD6126 was being investigated by AstraZeneca as a vascular disrupting agent (VDA). However, the trials were halted, after it became apparent that ZD6126 was too cardiotoxic at the required doses.[6]
