Design outcomes

Primary

MeasureTime frame
MTD after GX-051 intratumoral injection2 months

Secondary

MeasureTime frameDescription
Evaluation of antibody generation against IL-12 which is active ingredient of GX-0512 monthsWe will analyze anti-IL-12 antibody in blood by ELISA on the screening visit and the follw up visit. Result will report as existence or absence of the anti-body .
Adverse events after GX-051 intratumoral injection2 months
Changes of immune cell distribution in tumor tissue after GX-051 intratumoral injection2 monthsWe will analyze immune cells such as CD4+ T cell, CD8+ T cell, NK cell by FACS analysis on day 1(baseline), day 29(end of treatment) and day 57(follow up)
Changes of INF-γ and IL-12 levels in blood comparing to the baseline after GX-051 intratumoral injection2 monthsunit: pg/ml
Evaluation of long term safety examined by vital sign, physical examination, clinical laboratory tests, CT etc17 monthesSafety profile would be examined by vital sign, physical examination, clinical laboratory tests, CT etc
Anti-tumor response by RECIST 1.1 on computed tomography2 monthsResponse Evaluation Criteria in Solid Tumors (RECIST) are used to determine objective clinical response. Complete Rresponse (CR) is the disappearance of all target lesions, partial response (PR) is at least a 30% decrease in the target lesions, progressive disease (PD) is at least a 20% increase in the target lesions or appearance of one or more new lesions, and stable disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.
