General information about the trial
|
|||
Main objective of the trial |
The primary objective of the study was to estimate the efficacy of the combination consisting of cisplatin/pemetrexed and panitumumab in patients with wild-type KRAS (non-mutated status). The
progression-free survival rate at 6 months was compared to expectations derived from historical data, which were verified by a randomized control group without the antibody.
|
||
Protection of trial subjects |
The conduct of this study was in compliance with the Good Clinical Practice Guidelines and under the guiding principles detailed in the Declaration of Helsinki. The study was also carried out in keeping with applicable local law(s) and regulation(s).
Participants were monitored losely for toxicity, especially myelosuppression, renal, and gastrointestinal toxicity. An interim analysis of safety was presented to the Data Safety and Monitoring Board (DSMB) after documentation of the first 10 randomized patients in each arm. The DSMB received regular information on safety results of the trial.

Recruitment
|
||||||||||||||||||||||||||||
Recruitment details |
From the 26th Apr 2010 through 11th Jan 2013, a total of 98 patients were randomised at 13 participating centers in Germany. The assumption of 67 patients with KRAS wild type per arm (in total 134 patients) was not achieved. | |||||||||||||||||||||||||||
Pre-assignment
|
||||||||||||||||||||||||||||
Screening details |
Out of 98 randomized patients, 96 patients were included in the full analysis set. One patient had to be excluded because of the violation of inclusion criteria. Another patient withdrew his consent after randomisation but before the first cycle of combination therapy. Randomization was stratified by participating center. | |||||||||||||||||||||||||||

Notes [1] - There are no non-serious adverse events recorded for these results. It is expected that there will be at least one non-serious adverse event reported. Justification: In total, 40 patients experienced one or more SAE, 24 patients of Arm A and 16 patients of Arm B. Among them, 14 patients of Arm A and 8 patients of Arm B reported SAEs that were assessed as being drug related. With 24 versus 16 the number of patients with one or more SAEs was higher within the panitumumab arm as compared to the control arm. Furthermore, the total number of SAEs was also higher in the panitumumab arm as compared to the control arm (33 in Arm A versus 22 in Arm B). |

Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
A futility analysis was performed to support the safety assessment of the DSMB. On the basis of interim toxicity data and the futility analysis of PFS the DSMB recommended to immediately stop patient recruitment. |
