This is a phase 2, multi center, open label, single arm, clinical trial to be conducted in the United States. Subjects with metastatic colorectal cancer who failed (due to disease progression or toxicity) first line treatment containing fluoropyrimidine and oxaliplatin based chemotherapy with bevacizumab will be enrolled at approximately 60 to 80 centers.

Primary Outcome Measures:
  • Objective response rate at weeks 17 and 25, and best response rate; progressions-free survival at weeks 17 and 25; progression free survival time; disease control; duration of objective response; overall survival [ Time Frame: After disease progression, all subjects will be followed every 12 weeks + or - 2 weeks from the safety visit until the end of study (approximately 52 weeks after the last subject is enrolled). ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Incidence and severity of AEs, including AEs of interest for panitumumab; changes in selected laboratory values: Mg, potassium, calcium, creatinine, total bilirubin, alkaline phosphatase, AST, ALT, ANC, Hgb and platelet count. [ Time Frame: After disease progression, all subjects will be followed every 12 weeks + or - 2 weeks from the safety visit until the end of study (approximately 52 weeks after the last subject is enrolled). ] [ Designated as safety issue: Yes ]

Detailed Description:
This is a Multi-center, Open-label, Single-arm Trial Evaluating Panitumumab in Combination with FOLFIRI Therapy Following First-line FOLFOX and Bevacizumab Treatment of Metastatic Colorectal Cancer Study Phase: 2 Indication: Second-line metastatic colorectal cancer (mCRC) Primary Objective: To estimate the effect of Kras mutation status (wild type versus mutant) from tumor tissue on efficacy endpoints in subjects with mCRC receiving second-line FOLFIRI with panitumumab after failing first-line treatment containing fluoropyrimidine and oxaliplatin-based chemotherapy with bevacizumab Secondary Objective(s): To evaluate the safety profile (incidence of adverse events and significant laboratory changes) of second-line FOLFIRI with panitumumab Exploratory Objective(s): To investigate the incidence of potential biomarkers based on tumor cells and their effect(s) on selected safety and efficacy endpoints

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of metastatic adenocarcinoma of the colon or rectum
  • Available paraffin-embedded tumor tissue
  • Failure of first line treatment containing fluoropyrimidine and oxaliplatin based chemotherapy with bevacizumab for mCRC
  • Measurable disease
  • Adequate hematologic, renal, hepatic and metabolic function

Exclusion Criteria:

  • Radiotherapy ≤ 2 weeks prior to Day 1 of Cycle 1
  • Unresolved toxicity(ies) from prior anti cancer therapy that, in the opinion of the investigator, precludes the subject from study enrollment
  • Prior irinotecan therapy. anti EGFr therapy, or vaccine for the treatment of mCRC
  • CYP3A4 enzyme inducers, inhibitors, and substrates (eg, phenytoin, phenobarbital, carbamazepine, ketoconazole, rifampin, rifabutin, and St. John's Wort) ≤ 2 weeks prior to Day 1 of Cycle 1
  • Infection requiring systemic anti infectives completed ≤ 2 weeks prior to Day 1 of Cycle 1
  • Clinically significant cardiovascular disease
  • History of interstitial lung disease (eg, pneumonitis or pulmonary fibrosis)
  • Pulmonary embolism, deep vein thrombosis, or other significant thromboembolic event ≤ 8 weeks prior to Day 1 of Cycle 1
  • Any significant bleeding ≤6 weeks prior to Day 1 of Cycle 1, per the investigator's judgement
  • Gastroduodenal ulcer(s) determined by endoscopy to be active or uncontrolled gastrointestinal ulcer ≤ 4 weeks prior to Day1 of Cycle 1
  • Any co morbid disease or condition that could increase the risk of toxicity (eg, dihydropyrimidine deficiency, significant ascites, or pleural effusion)
  • Major surgery (requiring general anesthesia), open biopsy, or significant traumatic injury ≤4 weeks prior to Day1 of Cycle 1. Subjects must have recovered from surgery and have no significant complications
