AG-013736 In Combination With Gemcitabine Versus Gemcitabine Alone For Patients With Metastatic Pancreatic Cancer

Dose of axitinib (AG-013736) was confirmed if not more than 1 out of 6 participants experienced a DLT during first cycle. DLT included grade (Gr) 4 neutropenia or thrombocytopenia, greater than or equal to (>=) Gr 3 anemia or non hematological toxicities for >= 7 days (except alopecia) or >= Gr 1 hemoptysis or >=2 gram /24 hours proteinuria or inability to resume background chemotherapy or axitinib (AG-013736) dosing within 14 days of stopping due to treatment related toxicity.

Dose of gemcitabine was confirmed if not more than 1 out of 6 participants experienced a DLT during first cycle. DLT included grade (Gr) 4 neutropenia or thrombocytopenia, greater than or equal to (>=) Gr 3 anemia or non hematological toxicities for >= 7 days (except alopecia) or >= Gr 1 hemoptysis or >=2 gram /24 hours proteinuria or inability to resume background chemotherapy or axitinib (AG-013736) dosing within 14 days of stopping due to treatment related toxicity.

AUC (0-24) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to 24 hours (0-24).

Tmax was based on the actual time points when the samples were collected.

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

AUC (0 - ∞) = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - ∞). It is obtained from AUC (0 - t) plus AUC (t - ∞).

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

Data for this outcome measure are not reported here because the analysis population includes participants who were not enrolled in this study. ClinicalTrials.gov is designed for reporting results from only those participants who were enrolled in the study and described in the Participant Flow and Baseline Characteristics modules.

Percentage of participants with OR based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). Confirmed responses are those that persist on repeat imaging study at least 4 weeks after initial documentation of response. CR are defined as the disappearance of all lesions (target and/or non-target). PR are those with at least 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum of longest dimensions.

Time in days from the first documentation of objective tumor response to objective tumor progression or death due to any cancer. Duration of tumor response was calculated as the date of the first documentation of objective tumor progression or death due to cancer minus the date of the first CR or PR that was subsequently confirmed plus 1. DR was calculated for the subgroup of participants with a confirmed objective tumor response.

Time in days from randomization to first documentation of objective tumor progression or death due to any cause. PFS was calculated as first event date minus the date of randomization plus 1. Tumor progression was determined from oncologic assessment data (where data meet the criteria for progressive disease [PD]), or from adverse event (AE) data (where the outcome was "Death").

One year survival probability was defined as the probability of survival at one year after the date of randomization based on the Kaplan Meier estimate.

EORTC QLQ-C30: included functional scales (physical, role, cognitive, emotional, and social), global health status, symptom scales (fatigue, pain, nausea/vomiting), and single items (dyspnoea, appetite loss, insomnia, constipation/diarrhea, and financial difficulties). Most questions used 4-point scale (1 'Not at All' to 4 'Very Much'); 2 questions used 7-point scale (1 'Very Poor' to 7 'Excellent'). Scores averaged, transformed to 0-100 scale; higher score=better level of functioning or greater degree of symptoms. Change from baseline=Cycle/Day score minus baseline score.

QLQ-PAN26 consists of 26 questions (Qs) relating to disease symptoms, treatment (Tx) side effects and emotional issues specific to pancreatic cancer (PC). Questions include on altered bowel habits, pain, dietary changes, disease and Tx-related symptoms and issues related to the emotional and social well-being of participants with PC. All 26 Qs are answered on 4-point Likert scale ranging from '1=not at all' to 4='very much' and subsequently transformed into scales that range from 0-100. Higher scores on functioning scales=better functioning; higher scores on the symptom scales=more symptoms.
