Brief Summary:

This is an open label, multicenter, non-comparative, phase IV study of panitumumab monotherapy in Indian subjects with previously treated, wild-type Kirsten rat sarcoma viral oncogene homolog (KRAS) and wild-type Neuroblastoma rat sarcoma viral (v-ras) oncogene homolog (NRAS), metastatic colorectal cancer. This study is designed to fulfil the requirement of the Indian regulatory authority to characterize the safety and tolerability of panitumumab when administered to Indian subjects with wild-type KRAS and wild-type NRAS metastatic colorectal cancer. Approximately 58 Indian subjects with previously treated wild-type KRAS and wild-type NRAS, metastatic colorectal cancer will be enrolled in order to achieve the target enrollment of 50 evaluable subjects who have received at least one dose of panitumumab. Subjects will receive panitumumab 6 milligram/kilogram (mg/kg) intravenously every 14 days until disease progression, intolerability, withdrawal of consent, or death. All subjects will be followed at 4 weeks and 8 weeks after the last administration of panitumumab, unless the treatment was discontinued due to withdrawal of consent or death of the subject.

Arm	Intervention/treatment
Experimental: Panitumumab arm; Subjects will receive panitumumab 6 mg/kg intravenously as monotherapy every 14 days until disease progression, intolerability, withdrawal of consent, or death.	Drug: Panitumumab; Panitumumab is available as a concentrate for solution for infusion (sterile concentrate). It is a colorless solution that may contain, translucent to white, visible amorphous, proteinaceous panitumumab particles. Each milliliter (mL) of concentrate contains 20 mg panitumumab. Each vial contains 100 mg of panitumumab in 5 mL.

Outcome Measures

Primary Outcome Measures :

1. Number of subjects with adverse event. [ Time Frame: 8 months (average duration). ]
   Adverse events including medically significant laboratory changes- incidence, severity, causality and outcome will be collected from the signing of informed consent form until 8 weeks following discontinuation of study treatment due to disease progression, intolerability, withdrawal of consent or death.

Secondary Outcome Measures :

1. Progression free survival. [ Time Frame: Every 8 weeks (assessed up to average of 6 months) ]
   Progression free survival is defined as the interval between the treatment start date and the earliest date of disease progression per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 or death due to any cause.
2. Overall Response Rate. [ Time Frame: Every 8 weeks (assessed up to average of 6 months). ]
   Overall response rate is defined as the percentage of subjects with either a complete response (CR) or partial response (PR) at anytime as per RECIST version 1.1. Where CR is disappearance of all target lesions. Any pathological lymph nodes must be <10 millimeter (mm) in the short axis. PR is at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the baseline sum of the diameters (e.g. percent change from baseline).
3. Duration of response. [ Time Frame: Every 8 weeks (assessed up to average of 6 months). ]
   Duration of response is defined as the time from initial response (CR or PR) to date of disease progression per RECIST version 1.1.

Ages Eligible for Study:	18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:	All
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

• Subject or subject's legally acceptable representative has provided informed consent.
• Male or female >=18 years of age.
• Histologically or cytologically confirmed diagnosis of adenocarcinoma of the colon or rectum.

Metastatic disease.

• Wild-type KRAS (without mutation in exon 2 [codons 12 and 13], exon 3 [codons 59 and 61], and exon 4 [codons 117 and 146]) and wild-type NRAS (without mutation in exon 2 [codons 12 and 13], exon 3 [codons 59 and 61], and exon 4 [codons 117 and 146]) tumor status.

• Must have failed after fluoropyrimidine-, oxaliplatin-, and irinotecan-containing chemotherapy regimens for metastatic disease. Failure is defined as either disease progression (clinical or radiological) or intolerance to the regimen. Metastatic relapse within 6 months after completing adjuvant chemotherapy (with either an irinotecan or oxaliplatin containing regimen) will also be considered as treatment failure of a prior regimen for metastatic disease.
