PRIMARY OBJECTIVES:
I. To compare the duration of progression free survival 1 (PFS1) in patients with RAS wild type who have received induction leucovorin calcium, fluorouracil, and oxaliplatin (FOLFOX) + panitumumab and not progressed at 6 cycles and randomized to maintenance therapy with fluorouracil (5FU) based therapy with or without panitumumab.
SECONDARY OBJECTIVES:
I. To compare the response rate (RR) in patients with RAS wild type who are randomized to maintenance therapy with 5FU based therapy to those randomized to 5FU based therapy with panitumumab.
TERTIARY OBJECTIVES:
I. Progress free survival 2 (PFS2). II. To assess the adverse event (AE) profile and safety of the proposed treatment in this population.
III. To assess and compare the overall survival (OS) between the two treatment groups.
IV. To compare the quality of life (QOL) as measured by health state index (HIS) between patients who achieve partial response (PR) versus (vs.) those who progress and those who have stable disease during the induction phase.
V. To compare the QOL as measured by HSI between the two groups randomized to maintenance therapy.
VI. To assess the evolution of RAS mutation under treatment during induction phase as well as maintenance.
VII. To explore relationship between genomic and proteomic alterations of the tumor with response and PFS to panitumumab.
OUTLINE:
INDUCTION:
Patients receive panitumumab intravenously (IV) over 30-60 minutes, oxaliplatin IV over 2 hours, leucovorin calcium IV, and fluorouracil over 46-48 hours on day 1. Treatment repeats every 14 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
MAINTENANCE: Patients who are not candidates for surgery, have no disease progression, or do not have complete response after Induction are randomized to 1 of 2 arms.
ARM I: Patients receive panitumumab IV over 30 minutes, leucovorin calcium IV, and fluorouracil over 46-48 hours on day 1. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive capecitabine orally (PO) twice daily (BID) on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months.

- Progression free survival 1 [ Time Frame: From the date of randomization to the date of 1st documented disease progression or death due to any cause, whichever occurs first, assessed up to 7 months. ]Disease progression will be determined by comparing tumor measurement during maintenance therapy to baseline measurement before starting maintenance treatment using Response Evaluation Criteria in Solid Tumors 1.1. will be conducted based on the intent‐to‐treat population from the time of randomization.
- Treatment Response [ Time Frame: Up to 4 years ]Response will be evaluated using the international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guidelines (version 1.1)

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Metastatic or locally advanced (unresectable) colorectal cancer with histological confirmation of adenocarcinoma (patients with or without measurable disease by imaging are eligible)
- No prior systemic chemotherapy for metastatic disease; subjects who received adjuvant therapy with FOLFOX and at the time of recurrence are at least 6 months away from last chemotherapy are eligible for this study
- At the time of randomization to maintenance therapy only patients who didn't progress by Response Evaluation Criteria in Solid Tumors (RECIST) criteria are eligible; patients with complete response (CR) and those who are candidates for resection will not be eligible for randomization to maintenance therapy, subjects who undergo surgery potentially have curable disease with defined duration of treatment and use of EGFR in the adjuvant setting is deemed to be detrimental in these population; likelihood of achieving CR is low and standard of care in this unique patient population is not well defined
