Registered outcomes8

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryCorrelate Intratumoral Expression Level of Ribonucleotide Reductase Subunit 1 (RRM1) With Response to Gemcitabine in Patients With Advanced Pancreatic Cancer.Up to 2 years
Pearson's correlation coefficients ("r") will be calculated to summarize the relationship between RRM1 and response to gemcitabine. Coefficients are on a continuous scale ranging from -1 to +1 with a value of -1 indicating a perfect negative linear association of RRM1 and response to gemcitabine, a value of 0 indicating no association between RRM1 and response to gemcitabine, and a value of +1 indicating a positive linear association of RRM1 and response to gemcitabine.
Secondary
Correlate Intratumoral Expression Levels of Other Genes, Including Deoxycytidine Kinase (dCK), Equilibrative Nucleoside Transporter 1 (ENT1) and Concentrative Nucleoside Transporters 1 and 3 (CNT1 and CNT3), With Response to Gemcitabine.
Up to 2 years
Pearson's correlation coefficients ("r") will be calculated to summarize the relationship between deoxycytidine kinase (dCK), equilibrative nucleoside transporter 1 (ENT1) and concentrative nucleoside transporters 1 and 3 (CNT1 and CNT3), with response to gemcitabine in a table format. Coefficients are on a continuous scale ranging from -1 to +1 with a value of -1 indicating a perfect negative linear association of intratumoral expression levels and response to gemcitabine, a value of 0 indicating no association between intratumoral expression levels and response to gemcitabine, and a value of +1 indicating a positive linear association of intratumoral expression levels and response to gemcitabine.
Secondary
Correlate Intratumoral Expression Levels of Thymidylate Synthase (TS), Thymidine Phosphorylase (TP), Dihydropyrimidine Dehydrogenase (DPD), Orotate Phosphoribosyltransferase (ORPT) With Response to the Combination of Gemcitabine/S-1.
Up to 2 years
Pearson's correlation coefficients ("r") will be calculated to summarize the relationship between intratumoral expression levels of thymidylate synthase (TS), thymidine phosphorylase (TP), dihydropyrimidine dehydrogenase (DPD), orotate phosphoribosyltransferase (ORPT) with response to the combination of gemcitabine/S-1 in a table format. Coefficients are on a continuous scale ranging from -1 to +1 with a value of -1 indicating a perfect negative linear association of intratumoral expression levels and the combination of gemcitabine/S-1, a value of 0 indicating no association between intratumoral expression levels and response to the combination of gemcitabine/S-1, and a value of +1 indicating a positive linear association of intratumoral expression levels and response to the combination of gemcitabine/S-1.
SecondaryMedian Overall SurvivalUp to 2 yearsOverall survival will be defined from the date of receiving the first treatment until death
SecondaryNumber of Patients With Dose Modifications8 weeks after 6th patient is enrolledTreatment-related toxicities resulting in a dose modification be classified using the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 3 will be tabulated.
SecondaryPercentage of Patients Classified as Potential Biomarker RespondersAssessed after the first 5 weeks of treatment
Defined as the percentage of patients who will be categorized as potential biomarker responders if their CA19-9 has declined by \> 10 % from peak value (peak value may have been at either week 1 or 3) during the initial gemcitabine monotherapy phase
SecondaryMedian Time to ProgressionUp to 2 yearsTime to progression will be summarized according to the method of Kaplan and Meier
SecondaryPercentage of Patients With at Biomarker ResponseUp to 2 years
A biomarker response for any given line of therapy is defined as patients with a baseline CA19-9 level \> 75 units per cubic centimeter (U/cc) who demonstrate a \> 25% decline in their peak CA19-9 level, sustainable for at least 2 consecutive measurements
