Details and patient eligibility


This study is to determine the maximum tolerated dose(MTD), dose limiting toxicity(DLT), safety and pharmacokinetics(PK) profile of a single agent CKD-581 injection in Combination with Bortezomib and Dexamethasone in patients with Previously Treated Multiple Myeloma.

Full description

This is an open label, dose escalation study. Cohort of 3~6 patients receive escalation doses of CKD-581 until the maximum toleated dose(MTD) is determined. The MTD is defiend as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose limiting toxicity.


18 estimated patients




19+ years old


No Healthy Volunteers
