Primary Purpose: Treatment
|Official Title:||A Phase II Study of Panitumumab in Combination With FOLFIRI After Progression on FOLFIRI Plus Bevacizumab in KRAS(Kirsten Rat Sarcoma) and NRAS Wild-Type Metastatic Colorectal Cancer.|
- Progression free survival(PFS) [ Time Frame: Time from study day 1 to the time the patient is first recorded as having disease progression or death, assessed up to 2 years ]Continuous variables will be expressed by means, standard deviations and 95% confidence intervals. Estimated using the Kaplan-Meier estimator with confidence interval calculated based on the Brookmeyer-Crowley method.
- Frequency and severity of toxicities of the regimens, graded according to the NCI CTCAE v4.0 [ Time Frame: Up to 2 years ]Frequencies will be computed for discrete data.
- Overall response rate, as described in RECIST v1.1 criteria [ Time Frame: Up to 2 years ]
- Overall survival [ Time Frame: Time from study day 1 to the date of death or the last date the patient was known to be alive, assessed up to 1 year ]Continuous variables will be expressed by means, standard deviations and 95% confidence intervals. Kaplan-Meier estimator will be used.
|Study Start Date:||February 2013|
|Estimated Primary Completion Date:||December 2017 (Final data collection date for primary outcome measure)|
Experimental: Treatment (panitumumab, combination chemotherapy)
5-Fluorouracil, irinotecan, and panitumumab
Other Names:Drug: irinotecan hydrochloride
Other Names:Drug: fluorouracil
Other Names:Drug: leucovorin calcium
I. To determine the median progression-free survival in patients treated with leucovorin calcium, fluorouracil, and irinotecan hydrochloride (FOLFIRI) and panitumumab for K-ras and NRAS wild-type, metastatic colorectal carcinoma who have already progressed on FOLFIRI + Bevacizumab.
I. To determine the frequency and severity of toxicities of the regimens. II. To determine overall response rate. III. To determine the median overall survival and the overall survival rate at 1 year.
Patients receive panitumumab intravenously (IV) over 60-90 minutes, leucovorin calcium IV over 90 minutes, fluorouracil IV continuously over 46 hours, and irinotecan hydrochloride IV over 90 minutes on days 1 and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up periodically.
