Title   A Phase II Trial of Single Agent Axitinib as Maintenance Therapy for Patients with First Line Metastatic Colorectal Cancer (mCRC) (Colon Cancer)
Description   The primary objective of this trial is to determine the PFS (progression free survival, chances of staying free of the cancer progressing) of patients with first-line mCRC (metastatic colorectal cancer, colorectal cancer that has spread) treated with maintenance axitinib after initial treatment with FOLFOX (the chemo regimen of Folinic acid, Fluorouracil, and Oxaliplatin) plus bevacizumab.
IRB Number   Pro3958
Inclusion/Notes   INCLUSION:
  • Histologically or cytologically confirmed metastatic adenocarcinoma of the colon or rectum.

  • Patients must have measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (14).

  • No previous systemic therapy for metastatic colorectal cancer. Previous radiosensitizing chemotherapy is allowed, , if completed at least 4 weeks prior to Cycle 1 Day 1 of study treatment, and previous neoadjuvant and/or adjuvant chemotherapy is allowed, if completed at least 6 months prior to diagnosis of metastatic disease.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0 to 1 (see Appendix A).

  • Male or female patients 18 years-of-age.

  • Life expectancy 12 weeks.

  • Adequate hematologic function defined as: absolute neutrophil count (ANC) 1500/ L, Hemoglobin (Hgb) 9 g/dL (5.6 mmol/L), Platelets 100,000/uL.

  • Adequate liver function defined as: Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) <2.5 x the institutional upper limit of normal (ULN) or 5.0 x the institutional ULN in patients with liver metastases, total bilirubin within normal limits (WNL) (or 1.5 x the institutional ULN in patients with liver metastases; or total bilirubin 3.0 x ULN with direct bilirubin within normal limits in patients with well documented Gilbert Syndrome).

  • Adequate renal function defined as: serum creatinine 1.5 mg/dL OR calculated 24-hour creatinine clearance 60 mL/min.

  • Patients who are on coumadin should have an INR value within the therapeutic range (i.e., 2 to 3 x ULN). Patients who are on stable, chronic doses of coumadin are eligible.

  • Male patients willing to use adequate contraceptive measures (see Appendix D). Female patients who are not of child-bearing potential (see Appendix D), and female patients of child-bearing potential who agree to use adequate contraceptive measures (see Appendix D), who are not breastfeeding, and who have a negative serum or urine pregnancy test performed within 48 hours prior to start of treatment.

  • Willingness and ability to comply with the trial and follow-up procedures.

  • Ability to understand the investigative nature of this trial and give written informed consent.

EXCLUSION:
  • History or known presence of central nervous system (CNS) metastases.

  • Patients who have had a major surgical procedure (not including mediastinoscopyor significant traumatic injury 4 weeks prior to beginning treatment.

  • Women who are pregnant or lactating. All females of child-bearing potential must have negative serum or urine pregnancy tests within 7 days prior to study treatment (see Appendix D).

  • History of hypersensitivity to active or inactive excipients of any component of treatment (5 fluorouracil, bevacizumab, oxaliplatin, or axitinib), or known dipyrimidine dehydrogenase deficiency.

  • Patients with proteinuria at screening as demonstrated by: urine dipstick for proteinuria 2+ (patients discovered to have 2+
    proteinuria on dipstick urinalysis at baseline should undergo a 24 hour urine collection, and must demonstrate 1 g of protein/24 hours to be eligible).

  • Patients with a serious non healing wound, active ulcer, or untreated bone fracture.

  • Patients with evidence of bleeding diathesis or significant coagulopathy (in the absence of therapeutic anticoagulation).

  • Patients with history of hematemesis or hemoptysis (defined as having bright red blood of ½ teaspoon or more per episode) 1 month prior to study enrollment.

  • Patients requiring concomitant treatment with potent CYP3A4 or CYP1A2 inducers and CYP3A4 inhibitors (see Appendix E).

  • History of myocardial infarction or unstable angina 6 months prior to beginning treatment.

  • Inadequately controlled hypertension (defined as systolic blood pressure [BP] >150 mmHg and/or diastolic BP >100 mmHg while on antihypertensive medications).
  • Initiation of antihypertensive agents is permitted provided adequate control is documented at least 1 week prior to Day 1 of study treatment.
  • New York Heart Association Grade II or greater congestive heart failure (see Appendix B).

  • Serious cardiac arrhythmia requiring medication. Patients with chronic, rate-controlled atrial fibrillation are eligible.

  • Significant vascular disease (e.g., aortic aneurysm requiring surgical repair, or recent peripheral arterial thrombosis) 6 months prior to Day 1 of treatment.

  • History of abdominal fistula or gastrointestinal perforation 6 months prior to Day 1 of beginning treatment.

  • Concurrent severe, intercurrent illness including, but not limited to, ongoing or active infection, or psychiatric illness/social situations that would limit compliance with study requirements.

  • Any known positive test for human immunodeficiency virus, hepatitis C virus or acute or chronic hepatitis B infection.

  • Mental condition that would prevent patient comprehension of the nature of, and risk associated with, the study.

  • Use of any non-approved or investigational agent 28 days prior to administration of the first dose of study drug. Patients may not receive any other investigational or anticancer treatments while participating in this study.

  • Past or current history of neoplasm other than the entry diagnosis with the exception of treated non-melanoma skin cancer or carcinoma in situ of the cervix, or other cancers cured by local therapy alone and a disease free survival 5 years.

  • Infection requiring IV antibiotics.

  • Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter drug absorption (e.g. active inflammatory bowel disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome or significant small bowel resection).
