General information about the trial
|
|||
Main objective of the trial |
Response rate (using RECIST-Criteria vs 1.0)
|
||
Protection of trial subjects |
The treatment should be conducted exactly as described in the protocol. Any protocol deviation were reported. The recommendations of Good Clinical Practice (see ICH-GCP: International Conference on Harmonisation - Good Clinical Practice), valid since 17 January 1997, were met.
|
||
Background therapy |
Sedatives, antibiotics, analgesics, antihistamines, steroids, granulocyte-colony stimulating factor, erythropoetin, or other medications as well as red blood cells, platelets or fresh frozen plasma transfusions could be given to assist in the management of pain, infection, and other complications of the malignancy. Patients had to be pre-medicated with an antihistamine and corticosteroid before receiving the first three infusions of cetuximab. Premedication with an antihistamine and corticosteroid before subsequent infusions was recommended. Patients could be pre-medicated before oxaliplatin infusions according to local standard routine | ||

Recruitment
|
|||||||
Recruitment details |
Upon obtaining signed informed consent, screening evaluations were performed to confirm eligibility and to obtain baseline safety data. Between 14-Aug-2009 (First patient in) and 21-Nov-2013 (Last patient in) 60 patients were registered by 6 sites ( medical practices as well as hospitals) in Germany. | ||||||
Pre-assignment
|
|||||||
Screening details |
The selection of patients occurred through the investigator according to the inclusion and exclusion criteria after having informed the patient in writing and orally about the study and after the patient has signed the informed consent. These baseline examinations should be performed within 3 weeks before start of treatment. | ||||||

End point title |
Objective response rate (ORR) according to RECIST criteria [1] | |||||||||||||||||||||||||||||||||||||||||||||
End point description |
The primary target value of this study was the objective response rate, using RECIST criteria. Each set of tumor responses was assessed to determine the best overall response. ORR was defined by number of patients with CR+PR as best response.
|
|||||||||||||||||||||||||||||||||||||||||||||
End point type |
Primary
|
|||||||||||||||||||||||||||||||||||||||||||||
End point timeframe |
Tumor assessment was perforemd at baseline and every 8 weeks during during study therapy; after last study treatment administration tumor asessment was performed every
3 months until end of follow-up.
|
|||||||||||||||||||||||||||||||||||||||||||||
Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: Simon Two-Stage desgin. Altogether 37 patients of the ITT set had CR or PR as best response; this amounted to an ORR of 65%. DCR (CR+PR+SD) was 84.1%. In the first stage 25 responders and in the second stage 35 responders were observed, which was more than the necessary number (≥13 responders in the first stage and ≥25 responders after completion of the second stage) to reject the null hypothesis H0: p ≤ 0.35. |
