FOLFIRI and Panitumumab in Treating Patients With RAS and BRAF Wild-Type Metastatic Colorectal Cancer

• Status: Terminated
• Trial end date: 2017-09-13
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies how well fluorouracil, leucovorin calcium, and irinotecan hydrochloride (FOLFIRI) together with panitumumab work in treating patients with colorectal cancer that expresses the RAS and B-Raf proto-oncogene, serine/threonine kinase (BRAF) wild-type genes, has spread from the original site of growth to another part of the body (metastatic), resists the effects of treatment with prior cetuximab (or panitumumab) plus irinotecan hydrochloride-based therapy, and who have failed at least one subsequent non-anti-epidermal growth factor receptor (EGFR) containing treatment regimen. Drugs used in chemotherapy, such as fluorouracil, leucovorin calcium, and irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Monoclonal antibodies, such as panitumumab, may block tumor growth in different ways by targeting certain cells. Giving FOLFIRI together with panitumumab may be an effective treatment for colorectal cancer.

Exclusion Criteria:

• History of severe anti-EGFR toxicity requiring drug discontinuation or dose-modification within the first 4 months of prior anti-EGFR therapy

• History of intolerance to irinotecan at dose-intensity of 125 mg/m^2/2 weeks or lower

• Current use (or planned use during the treatment period) of other investigational agents, or biological, chemotherapy, radiation or other anti-tumor therapy

• Co-medication that may interfere with study results; e.g. immuno-suppressive agents other than corticosteroids, such as systemic cyclosporine and tacrolimus

• No St John's wort supplement or other herbal supplementation is allowed while on trial; patients are not to take grapefruit juice during study treatment

• Use of drugs known to inhibit UDP glycosyltransferase 1 family, polypeptide A1 gene (UGT1A1), such as Atazanavir, Gemfibrozil, Indinavir, or Ketoconazole while on study treatment; (patients using these drugs must not take these drugs on the day study treatment begins and for the duration of study treatment)

• Planned use of strong cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inhibitors or CYP3A4 inducers while on study treatment unless deemed clinically necessary with no reasonable alternatives and with expressed permission from the principal investigator

• Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures, e.g., infection/inflammation, intestinal obstruction, unable to swallow medication, social/psychological issues, etc

• Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
