The Study of Metastatic Pancreatic Adenocarcinoma
Primary objective: the maximum tolerated dose of S-1 in the SLOG regimen
Secondary objectives: the dose-limiting toxicity of the regimen
Metastatic Pancreatic Adenocarcinoma
|Study Design:||Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase I/II Trial of Biweekly S-1, Leucovorin, Oxaliplatin and Gemcitabine (SLOG) in Metastatic Pancreatic Adenocarcinoma|
- to determine the following items in patients with metastatic pancreatic adenocarcinoma receiving SLOG [ Time Frame: one year ] [ Designated as safety issue: Yes ]Patients will be entered in cohorts of three. In any dose level of S-1, if none develops DLT as listed after the first two doses of SLOG chemotherapy, another cohort of 3 patients will be accrued to the next dose level. If at any time two or more patients develop DLT at the same dose level, the dose escalation will be terminated, and the prior dosage level will be considered the MTD.
- to evaluate the following items in patients with metastatic pancreatic adenocarcinoma receiving SLOG treatment, [ Time Frame: one year ] [ Designated as safety issue: Yes ]9.2.1 Simon's optimal two-stage design will be used to determine the target patient number for the phase II part of this study. Using the approach, we test a null hypothesis that the true-response probability is less than an uninteresting level (p0) of 25% against the alternative hypothesis that the true response probability is at least as great as a target level (p1) of 40%. Response probabilities less than 25% will be considered inactive while response probabilities greater than 40% will be called highly effective.

Experimental: Statin dose titration
S-1 20-40 mg/m2/b.i.d., day 1-7;Leucovorin 20 mg/m2/b.i.d., day 1-7;Oxaliplatin 85 mg/m2 in 250 mL of D5W,given as 2-hour intra-venous infusion, day 1;Gemcitabine 800 mg/m2 in 250 mL of normal saline, given as fixed dose-rate infusion,day 1;After the administration of gemcitabine, the infusion line should be flushed with 20 ml of normal saline and then 50 ml of 5% glucose solution before the administration of oxaliplatin; Every 14 days, as one cycle.Prophylactic G-CSF or GM-CSF will not be allowed in this study. In case of grade 4 or complication neutropenia, patients may receive G-CSF according to the regulation of National Insurance Bureru treated with appropriate antibiotics. Therapeutic G-CSF may be used at the discretion of attending physicians.
Biweekly S-1, Leucovorin, Oxaliplatin and Gemcitabine (SLOG) in metastatic pancreatic adenocarcinoma
Other Name: G-CSF
Phase I: 2~24 patients Phase II: Considering a design with p0 = 0.25 and p1 = 0.40 for which error is 0.10 and errors is 0.20, these constraints can be met with a two-stage Simon's design of 25 patients in the first stage and 27 patients in the second stage.
