This 2 part study will evaluate the safety and efficacy of a combination of Avastin, Tarceva and Xeloda (ATX) as second-line treatment in patients with locally advanced and/or metastatic pancreatic cancer. In the first part of the study, cohorts of patients will receive escalating doses of combination treatment to determine the maximum tolerated dose. The recommended dose will be used in the second part of the study to determine the efficacy of the ATX regime, in terms of its effect on disease progression. The anticipated time on study treatment is 3-12 months, and the target sample size is \<100 individuals.

Part 2: Percentage of Participants Free From Disease Progression
As per Response Evaluation Criteria In Solid Tumors (RECIST) version (v) 1.1, progressive disease (PD) is defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of 1 or more new lesions (target and non-target lesions) or the unequivocal progression of existing non-target lesions.
Time frame: Month 6

Part 2: Percentage of Participants With Disease Control
A participant was defined as having controlled disease if they sustained a Complete Response (CR) or Partial Response (PR) or Stable Disease (SD) during the assessment. As per RECIST v1.1, CR is defined as the disappearance of all target and non-target lesions and normalization of tumor marker level; PR is defined as at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the screening sum longest diameter; SD for target lesions is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum longest diameter since the treatment started and SD for non-target lesions defined as persistence of 1 or more non-target lesion(s) or/and maintenance of tumor marker level above the normal limits.
Time frame: From baseline thereafter, every 6 weeks (±7 days), then 1 week after last dose (follow-up), thereafter every 6 weeks (±7 days) until disease progression (up to Week 259)
Part 2: Percentage of Participants With Clinical Benefit Response
Clinical benefit response was defined as a composite of pain control, Karnofsky performance status (KPS), and weight. The KPS allows participants to be classified as per their functional impairment (abnormal function). It was recorded on an 11-point scale; 0= "dead" to 100= "Normal, no complaints, no evidence of disease" and sub-divided to 3 categories; 0 to 40 = "Unable to care for self, requires institutional or hospital care or equivalent, disease may be rapidly progressing"; 50 to 70= "Unable to work, able to live at home and care for most personal needs, varying amount of assistance needed and 80 to 100= "Able to carry on normal activity; no special care is needed".
Time frame: One week before start of study treatment and weekly until disease progression or death (Up to Week 259)
Part 2: Overall Survival
Survival was the interval of time from date of first dose of study medication to date of death at any time. Participants who had not died were censored at the date of last contact when they were known to be alive.
Time frame: From baseline until death (Up to Week 259)
