Measure Type Secondary
Measure Title Overall Objective Response Rate (ORR)
Measure Description

Summary of overall objective response rate based on tumor assessment by the Independent Review Committee (IRC) as per Response Evaluation Criteria in Solid Tumours (RECIST) criteria. ORR was defined as the proportion of patients with confirmed Complete Response (CR) or confirmed Partial Response (PR) relative to the total number of patients in the analysis population.

Per RECIST v 1.0 target lesions evaluation and assessed by tumor imaging: Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): >=30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.

The study was not powered for comparison of ORR between the two arms (non-comparative, open-label study).

Time Frame From the date of the first randomization until the study data cut-off date, 14 April 2011 (approximately 26 months)

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
The overall survival (OS) data are severely limited due to the low number of events (<50%) in both arms, therefore median OS cannot be accurately estimated due to limitations of available data.
