Trial Outcomes & Findings for Phase II Study of Irinotecan and Panitumumab (NCT NCT00836277)

NCT ID: NCT00836277

Last Updated: 2016-11-15

Results Overview

Response rate (RR) = the # participants with partial response (PR) + # participants with (CR) / # participants with (PR) + # participants with (CR ) + # participants with (SD) + # participants with (PD). This proportion was subsequently multiplied by 100. RECIST v1.0 criteria for Target Lesions was used: Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD; Progressive Disease (PD): At least a 20% increase in the sum of the 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): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started

PRIMARY outcome

Timeframe: Up to 14 months

Using RECIST v1.0 criteria, clinical benefit rate (CBR) = # participants with (PR) + # participants with (CR) + # participants with (SD) / # participants with (PR) + # participants with (CR) + # participants with (SD) + # participants with (PD). This proportion was subsequently multiplied by 100. RECIST v1.0 criteria for Target Lesions is defined as: Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD; Progressive Disease (PD): At least a 20% increase in the sum of the 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): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.

SECONDARY outcome

Timeframe: Up to 45 months (cohort)

Survival time the is free of disease progression. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
