Trial Outcomes & Findings for Phase II Study of Metastatic Melanoma With Lymphodepleting Conditioning and Anti-gp100:154-162 TCR Gene Engineered Lymphocytes (NCT NCT00509496)

NCT ID: NCT00509496

Last Updated: 2013-01-15

Results Overview

Clinical tumor regression was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). Complete response (CR) is a disappearance of all target lesions. Partial response (PR) is at least a 30% decrease in the sum of the longest diameter (LD) of target lesions taking as reference the baseline sum LD. Progressive disease (PD) is at least a 20% increase in the sum of LD of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Stable disease (SD)is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD taking as references the smallest sum LD.
