Detailed Description
Esophageal cancer is a highly lethal malignancy that is increasing in incidence, especially the histologic subtype of adenocarcinoma. Fully 50% of patients present with advanced, incurable disease. Of the remainder who are diagnosed at curable stages, at most 30% are long-term survivors. Advances in therapy for both local and advanced disease have been stagnant in the past few decades. As such, there is an urgent need for advances in therapy. The development of modern cytotoxic chemotherapy and in particular, biologically targeted agents, provides hope for improving the outcome in these patients.
The semi-synthetic derivative of camptothecin, irinotecan, is active in esophageal adenocarcinoma, both alone and in combination with cisplatin. Use as front-line therapy in both multi-modality regimens and combination chemotherapy is common. More recently, the elucidation of the role of the epidermal growth factor receptor (EGFR) pathway in esophageal cancer has resulted in the pre-clinical and clinical study of the activity of EGFR directed agents for treatment of esophageal cancer.
The anti-EGFR antibodies, panitumumab and cetuximab, are active as both single agents and in combination with cytotoxic chemotherapy in patients with colorectal adenocarcinoma. In particular, the combination of irinotecan and cetuximab is active for irinotecan refractory colorectal cancer, while panitumumab is active compared with best supportive care. In our clinic, we have empiric evidence for the unexpectedly significant activity of the combination of cetuximab and irinotecan as third-line treatment for advanced esophageal adenocarcinoma. Panitumumab has the clinical advantages, compared with cetuximab, of being fully human,, thus resulting in a lower frequency of infusion reactions.
This recent experience with these targeted agents in solid tumors, while still promising, has yielded relatively modest results.7-11 Notably, however, retrospective analyses of clinical trials are consistently revealing that differences in treatment effect between subgroups of patients can be associated with specific molecular profiles.12-18 These findings suggest the potential for a more rational approach to trial design that would use patient and tumor characteristics to select patients for therapy, thus enriching the population of responders.

- Hemoglobin ≥ 9.0 g/dL
- Creatinine < or = to 1.5 mg/dL
- Creatinine clearance > or = to 50 mL/min calculated by the Cockcroft-Gault method as follows:
- Male creatinine clearance = (140 - age) x (weight in Kg) / (serum Cr x 72)
- Female creatinine clearance = (140 - age) x (weight in Kg) x 0.85 / (serum Cr x 72)
- Aspartate aminotransferase (AST) < or = to 3 x ULN (if liver metastases less than or equal to 5 x ULN)

- Total bilirubin < or = to 1.5 x ULN
- Magnesium ≥ lower limit of normal
- Potassium > or = to lower limit of normal
- Because the effects of irinotecan and panitumumab on the developing human fetus are unknown, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation.
Exclusion Criteria:
- History or known presence of central nervous system (CNS) metastases unless CNS metastases have been irradiated and are stable.
- History of another primary cancer, except:
- Curatively treated in situ cervical cancer
- Curatively resected non-melanoma skin cancer
- Other primary solid tumor curatively treated with no known active disease present and no treatment administered for greater than or equal to 5 years prior to enrollment
- Pre-existing peripheral neuropathy > grade 1.
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to panitumumab or irinotecan.
- Patients receiving any medications or substances that are established or probable inhibitors or inducers of P450 3A4 are ineligible.
- Prior anti-EGFr antibody therapy (eg, cetuximab) or treatment with small molecule EGFr inhibitors (eg, gefitinib, erlotinib, lapatinib)
- Radiotherapy < or = to 14 days prior to enrollment.
- Systemic chemotherapy, hormonal therapy, immunotherapy, or experimental or approved proteins/antibodies (or small molecules for Phase I studies) (eg, bevacizumab)< or = to 30 days before enrollment
- Subjects requiring chronic use of immunosuppressive agents (eg, methotrexate, cyclosporine)
- Any investigational agent or therapy < or = to 30 days before enrollment
- Prior therapy with Irinotecan or panitumumab.
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- History of interstitial lung disease (e.g. pneumonitis or pulmonary fibrosis) or any evidence of interstitial lung disease on baseline chest CT scan
- History of any medical or psychiatric condition or laboratory abnormality that in the opinion of the investigator may increase the risks associated with the study participation or investigational product(s) administration or may interfere with the interpretation of the results.
- Women who test positive for serum or urine pregnancy test < 72 hours before randomization or is breast feeding
- Known positive test(s) for acute or chronic active hepatitis B infection
- Major surgery within 28 days or minor surgery within 14 days of study enrollment
- Men or women of child-bearing potential (women who are post-menopausal < 52 weeks, not surgically sterilized, or not abstinent) not consenting to use adequate contraception (per institutional standard of care) during treatment and for six months after the last investigational product(s) administration
- Any underlying condition which in the opinion of the principal investigator will interfere with safety or with compliance with the study.

Response Rate (RR)
Time Frame: Up to 14 months

Response rate (RR) = the # participants with partial response (PR) + # participants with (CR) / # participants with (PR) + # participants with (CR ) + # participants with (SD) + # participants with (PD).
This proportion was subsequently multiplied by 100.
RECIST v1.0 criteria for Target Lesions was used: Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): At least a 30% decrease in the sum of the LD of target lesions, taking as reference the baseline sum LD; Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions; Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started

Clinical Benefit Rate (CBR)
Time Frame: Up to 14 months

Using RECIST v1.0 criteria, clinical benefit rate (CBR) = # participants with (PR) + # participants with (CR) + # participants with (SD) / # participants with (PR) + # participants with (CR) + # participants with (SD) + # participants with (PD).
This proportion was subsequently multiplied by 100.
