Safety Study of Increasing Doses of CKD-516 in Patients With Advanced Solid Cancers

A phase I study is conducted to determine the maximum tolerated dose (MTD), dose limiting toxicity (DLT), safety and pharmacokinetics (PK) profile of a single agent CKD-516 injection on twice-weekly schedule in patients with advanced solid cancers failed to standard therapy. The usefulness of the this regimen is evaluated by response rate, progression free survival and vascular disruption effect by Dynamic Contrast-Enhanced MRI (DCE-MRI) or DWI.

This is an open label, dose escalation study. Patients receive CKD-516 IV over 30 minutes on day 1, 4, 8, 11 every 3 weeks in the absence of unacceptable toxicity or disease progression. Cohorts of 3\~6 patients receive escalating doses of CKD-516 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose limiting toxicity.
