A Study of PRO95780 in Combination With Cetuximab and Irinotecan Chemotherapy or the FOLFIRI Regimen With Bevacizumab in Patients With Previously Treated Metastatic Colorectal Cancer (APM4187g)

This study has been completed.

First received: July 3, 2007
Last updated: May 18, 2017
Last verified: May 2017
This is a Phase Ib, open-label, multicenter, dose-escalation study designed to assess if PRO95780 in combination with two different irinotecan-containing regimens is safe and tolerable in patients with metastatic colorectal cancer (mCRC) who have progressed following, or cannot tolerate, first-line therapy with 5-fluorouracil-, oxaliplatin-, and bevacizumab-containing regimens. This study will also make a preliminary assessment of the anti-tumor activity of PRO95780 in combination with irinotecan and cetuximab or the FOLFIRI regimen plus bevacizumab.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Signed informed consent
  • Age ≥ 18 years
  • Histologically confirmed CRC with evidence of metastases and measurable tumor lesions
  • Documented disease progression following, or intolerance to, treatment with 5-fluorouracil, oxaliplatin, and bevacizumab-based therapy

  • Willingness and capability to be accessible for study follow-up

Exclusion Criteria:

  • Patients who have a Kras mutation will be excluded from receiving cetuximab-containing regimens
  • Prior radiotherapy to a measurable metastatic lesion(s) to be used for response assessment, unless the lesion has progressed subsequent to the radiotherapy
  • Recent radiotherapy to a peripheral lesion, thoracic, abdominal, or pelvic field
  • Recent chemotherapy, hormonal therapy, or immunotherapy

  • Other invasive malignancies within 5 years
  • History or evidence of active central nervous system (CNS) disease
  • Current or recent participation in another experimental drug study
  • Clinically significant cardiovascular disease
  • Active infection requiring parenteral antibiotics
  • Recent major surgical procedure, open biopsy, significant traumatic injury, fine needle aspirations, or anticipation of need for major surgical procedure during the course of the study
  • Known or suspected to be positive for the human immunodeficiency virus (HIV)
  • Known to be positive for hepatitis C or hepatitis B surface antigen
  • History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates use of an investigational drug or specified study treatment
  • Pregnancy (positive pregnancy test) or breast feeding
  • Serious, non-healing wound, ulcer, or bone fracture
  • Known sensitivity to any of the products administered during the study
  • Any disorder that compromises the ability of the patient to provide written informed consent and/or comply with study procedures
