Experimental: Panitumumab Plus FOLFIRI
Participants received panitumumab as an intravenous (IV) infusion at a dose of 6 mg/kg plus a standard chemotherapy regimen (FOLFIRI) consisting of 5-fluorouracil (5-FU), leucovorin and irinotecan. Treatment was administered in cycles every two weeks.
|
Drug: Panitumumab
Panitumumab was administered by IV infusion on Day 1 of each 14-day cycle, just before administration of FOLFIRI chemotherapy.
Other Name: Vectibix® Drug: FOLFIRI FOLFIRI chemotherapy was initiated on Day 1 of each treatment cycle at the following starting doses: irinotecan 180 mg/m^2, leucovorin 400 mg/m^2 racemate (or 200 mg/m^2 I-leucovorin), 5-FU bolus 400 mg/m^2, 5-FU infusion 2400 mg/m^2. |
|
Active Comparator: FOLFIRI Alone
Participants received standard chemotherapy regimen (FOLFIRI) consisting of 5-FU, leucovorin and irinotecan. Treatment is administered in cycles every two weeks.
|
Drug: FOLFIRI
FOLFIRI chemotherapy was initiated on Day 1 of each treatment cycle at the following starting doses: irinotecan 180 mg/m^2, leucovorin 400 mg/m^2 racemate (or 200 mg/m^2 I-leucovorin), 5-FU bolus 400 mg/m^2, 5-FU infusion 2400 mg/m^2. |
Primary Outcome Measures :
- Progression-free Survival (PFS) [ Time Frame: From randomization until the data cut-off date of 8 April 2008. Maximum follow-up time was 17 months. ]
Progression-free survival was defined as the time from randomization to first disease progression per modified Response Evaluation Criteria in Solid Tumors (RECIST) criteria or death, based on independent central radiological assessment. Participants who were alive but did not meet criteria for progression by the data cutoff date were censored at their last evaluable disease assessment date.
Progressive disease is defined as a ≥ 20% increase in the size of target lesions or unequivocal progression of existing non-target lesions or any new lesions.
- Overall Survival [ Time Frame: From randomization until the data cut-off date of 30 April 2009. Maximum follow-up time was 33 months ]Overall survival was defined as the time from randomization to the date of death. Participants who had not died by the analysis data cutoff date had their time of death censored at their last contact date.
Secondary Outcome Measures :
- Percentage of Participants With an Objective Response [ Time Frame: Every 8 weeks until disease progression up to the data cut-off date of 30 April 2009. Maximum time on follow-up was 33 months. ]Participants were evaluated for tumor response per the modified Response Evaluation Criteria in Solid Tumors (RECIST) criteria every 8 weeks until disease progression. Objective response was defined as the incidence of either a confirmed complete or partial response (CR or PR) while on study, as determined by blinded independent central review and confirmed no less than 4-weeks after the criteria for response are first met. CR: Disappearance of all target and non-target lesions and no new lesions. PR: At least a 30% decrease in the sum of the longest diameter of target lesions and no progression of non-target or no new lesions, or, disappearance of all target lesions and the persistence of ≥ 1 non-target lesion not qualifying for either CR or progressive disease. Participants without a post-baseline assessment were considered non-responders.
- Time to Disease Progression [ Time Frame: From randomization until the data cut-off date of 30 April 2009. Maximum follow-up time was 33 months ]
Time to progression was defined as the time from the randomization date to the date of first observed disease progression per the modified RECIST criteria. Participants not meeting these criteria by the analysis data cutoff date were censored at their last evaluable disease assessment date.
Progressive disease is defined as a ≥ 20% increase in the size of target lesions or unequivocal progression of existing non-target lesions or any new lesions.
- Duration of Response [ Time Frame: From randomization until the data cut-off date of 30 April 2009. Maximum follow-up time was 33 months ]
Calculated only for those participants with an objective response as the time from the first objective response (subsequently confirmed within no less than 4 weeks) to first observed disease progression per modified-RECIST criteria. Participants not meeting these criteria by the analysis data cutoff date were censored at their last evaluable disease assessment date.
Progressive disease is defined as a ≥ 20% increase in the size of target lesions or unequivocal progression of existing non-target lesions or any new lesions.
- Number of Participants With Adverse Events (AEs) [ Time Frame: From randomization until the data cut-off date of 30 April 2009. Maximum follow-up time was 33 months. ]A serious adverse event (SAE) is defined by regulatory authorities as one that • is fatal • is life threatening (places the subject at immediate risk of death) • requires in-patient hospitalization or prolongation of existing hospitalization • results in persistent or significant disability/incapacity • is a congenital anomaly/birth defect • other significant medical hazard. The relationship of the adverse event to the study treatment was assessed by the Investigator by means of the question: "Is there a reasonable possibility that the event may have been caused by the study treatment?"
