Detailed Description
Current cancer therapies often produce an initial reduction in tumour size but may not have long term benefits. One possible explanation for this is the presence cancer cell known as a cancer stem cells. Cancer stem cells represent a small part of the tumour but are believed to be responsible for much of the growth and spread of the cancer. They may also be more resistant to traditional therapy, such as chemotherapy and radiation therapy.
The purpose of this study is to test the safety and determine the optimal dose of a new experimental drug, demcizumab, when given in combination with gemcitabine, a drug that is a standard treatment for advanced pancreatic cancer that has not been treated previously with chemotherapy. Demcizumab is a humanized monoclonal antibody (a protein made in the laboratory) and was developed to target cancer stem cells. The way the body handles demcizumab will also be investigated.
Up to 50 subjects will be enrolled at up to 8 centers in Australia, New Zealand, and Spain. Up to 28 days (4 weeks) prior to treatment you will undergo testing to determine your eligibility to take part in this study, and then if you are enrolled in the study you will receive intravenous (in the vein) infusions of the demcizumab administered once every 2 weeks, and gemcitabine and Abraxane® administered weekly for 3 weeks, out of every 4 weeks. After 9 weeks, you will undergo assessments to determine the status of your disease. If there is no evidence of progression of your disease or if your tumor is smaller, you will continue to receive one additional infusion of demcizumab, and you will continue to receive infusions of gemcitabine and Abraxane® once weekly for 3 consecutive weeks out of every 4 weeks until it has been shown that your cancer has progressed. You will undergo assessments every 8 weeks thereafter to determine the status of your disease. If there is no evidence of progression of your disease or if your tumor is smaller, you will continue to receive one additional infusion of demcizumab, and you will continue to receive infusions of gemcitabine and Abraxane® once weekly for 3 consecutive weeks out of every 4 weeks until it has been shown that your cancer has progressed. You will undergo assessments every 8 weeks thereafter to determine the status of your disease.
In addition to routine testing of blood and urine (for complete blood counts with differential and platelets, coagulation studies to determine how quickly your blood is clotting , serum chemistries, B-type natriuretic peptide [BNP] and Troponin I which indicates how well your heart if working, and urinalysis), special tests will be performed during the study at specific time points.
In addition, you will have and ECG and Doppler echocardiogram performed during screening, then every 28 days on study and at treatment termination. Your Doppler echocardiograms may be sent to a Cardiologist at another hospital who may perform a central read on some of the Doppler echocardiograms in this study. Finally, you will have a head CT or MRI at baseline and CT scans and/or other radiographs performed every 56 days to assess the status of your tumor.
The study includes an optional part which will investigate how variations in people's genetic makeup affect their response to medications. This involves the collection of one blood sample just before participants receive their first dose of study treatment. DNA will be extracted from the blood sample for testing.

Description
Inclusion criteria
- Subjects must have histologically or cytologically confirmed locally advanced or metastatic pancreatic cancer. In addition, subjects must have a tumor that is at least 1 cm in a single dimension and is radiographically apparent on Computed Topography (CT) or Magnetic Resonance Imaging (MRI). Prior chemotherapy or radiotherapy is not allowed.
- Age >21 years
- Eastern Cooperative Oncology Group (ECOG) performance status <2 (see Appendix B)
- Life expectancy of more than 3 months
Subjects must have normal organ and marrow function as defined below:
- Leukocytes >3.5 x 109/L
- Absolute neutrophil count >1.25 x 109/L
- Hemoglobin >100 g/L
- Platelets >125 X 109/L
- Total bilirubin <2 X institutional upper limit of normal (ULN)
- Aspartate aminotransferase (AST/SGOT) and alanine aminotransferase (ALT/SGPT) <5 X institutional ULN
- Alkaline phosphatase <5 X institutional ULN
- International normalized ratio (INR) and activated partial thromboplastin time (aPTT) within institutional ULN
- Creatinine <1.5 X institutional ULN OR
- Calculated creatinine clearance >60 mL/min using the Cockcroft and Gault formula as follows:
Creatinine clearance (mL/min) = (140 - age) x ideal body weight [kg] 0.814 x serum creatinine [µmol/L] For women, multiply the value from the equation above by 0.85. Where age is in years, weight is in kg, and serum creatinine is in µmol/L
- Women of childbearing potential must have had a prior hysterectomy or have a negative serum pregnancy test and be using adequate contraception prior to study entry and must agree to use adequate contraception from study entry through at least 6 months after discontinuation of study drug. Men must also agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and from study entry through at least 6 months after discontinuation of study drug. Should a woman enrolled in the study or a female partner of a man enrolled in the study become pregnant or suspect she is pregnant while participating in this study or within 6 months after discontinuation of study drug, the Investigator should be informed immediately.
- Ability to understand and the willingness to sign a written informed consent document
Exclusion Criteria
Subjects who meet any of the following criteria will not be eligible for participation in the study:
- Subjects receiving any other investigational agents or anti-cancer therapy.
- Subjects with brain metastases (subjects must have a CT scan or MRI of the head within 28 days prior to enrollment to rule out brain metastases), uncontrolled seizure disorder, or active neurologic disease
- History of a significant allergic reaction attributed to humanized or human monoclonal antibody therapy
