Trial Outcomes & Findings for Allogeneic Natural Killer (NK) Cells in Patients With Advanced Metastatic Breast Cancer (NCT NCT00376805)

NCT ID: NCT00376805

Last Updated: 2017-12-28

Results Overview

Successful Natural Killer (NK) cell expansion is defined as detection of an absolute circulating donor-derived NK cell count of \>100 cells/ul of whole blood 14 days after infusion with \<5% donor T and B cells in mononuclear population (in metastatic breast cancer patients).

Timeframe: 6 Months, 1 Year

Defined by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria: * Complete Response (CR: Disappearance of all target lesions * Partial Response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions * Stable Disease (SD): Neither sufficient shrinkage to qualify for PR or sufficient increase to qualify for PD * Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions of appearance of one or more new lesions of clinical benefit (CB; stable disease for greater than 6 months.
