Официальное название

An Open Labelled Phase III Adjuvant Trial of Disease-free Survival in Patients With Resected Pancreatic Ductal Adenocarcinoma Randomized to Allocation of Oxaliplatin- or Gemcitabine-based Chemotherapy by Standard Clinical Criteria or by a Transcriptomic Treatment Specific Stratification Signature

Обзор

This is a multicentre open labelled phase III adjuvant trial of disease-free survival in patients with resected pancreatic ductal adenocarcinoma randomized to allocation of oxaliplatin- or gemcitabine-based chemotherapy by standard clinical criteria (control arm) or by a transcriptomic treatment specific stratification signature or TSS (test arm).

Подробное описание

The main purpose and primary objective of the study is to determine whether disease free survival in patients with resected pancreatic ductal adenocarcinoma (PDAC) treated with standard adjuvant chemotherapy regimens (oxaliplatin- or gemcitabine-based), is superior using allocation based on a treatment specific signature (TSS), compared to the same chemotherapy regimens allocated according to standard clinical criteria.

Secondary objectives of the study are to assess overall survival (median, 3 year survival rate), metastasis free survival; survival based on targeted signatures (TSS) in test versus control arms, and survival using targeted therapies initially on relapse compared to standard first-line therapies on relapse.

In addition, ESPAC-6 optional translational research programme will obtain tumor specimens and blodd samples to identify biomarkers that may predict response to chemotherapy or relapse.

ESPAC-6 will also generate a biobank of matched patient-derived organoids (PDOs) to provide an experimentally tractable model system for the development and testing of biomarker-driven personalised therapies.

ESPAC-6 translational research programme, will also develop a longitudinal blood biobank to analyse clinically relevant circulating biomarkers, such as blood proteins, metabolites and/or circulating-free tumour DNA.
