ATX Study:A Study of Avastin (Bevacizumab), Tarceva (Erlotinib) and Xeloda (Capecitabine) in Patients With Locally Advanced and/or Metastatic Pancreatic Cancer

MTD for each of the medications was defined as the lowest dose studied which resulted in dose limiting toxicity (DLT) in at least 33 percent (%) of participants of the same quality category. DLT was defined as any greater than or equal to (>=) Grade (G) 3 or G4 toxicity; >= G3 non-hematological toxicities directly related to study treatment (other than untreated nausea/vomiting, alopecia, G3/G4 bilirubinemia for less than 7 days due to edema of the ductus choledochus and anemia); G4 thrombocytopenia, neutropenia lasting >= 7 days or G3 thrombocytopenia with complications, requiring transfusions, febrile neutropenia; stopping of oral CAP and/or ERL intake for >= 7 days, and/or cancellation of one or more BEV infusion(s) due to adverse events (AEs).

Once the MTD was reached then the preceding lower dose level was used as PRD. MTD for each of the medications was defined as the lowest dose studied which resulted in dose limiting toxicity (DLT) in at least 33% of participants of the same quality category. DLT was defined as >= G3 or G4 toxicity; >= G3 non-hematological toxicities directly related to study treatment (other than untreated nausea/vomiting, alopecia, G3/G4 bilirubinemia for less than 7 days due to edema of the ductus choledochus and anemia); G4 thrombocytopenia, neutropenia lasting >= 7 days or G3 thrombocytopenia with complications, requiring transfusions, febrile neutropenia; stopping of oral CAP and/or ERL intake for >= 7 days, and/or cancellation of one or more BEV infusion(s) due to AEs. If MTD was not defined for a drug treatment then the maximum planned dose of that particular drug was considered as PRD for Part 2.

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.

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.

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".

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.
