Lead: FCRB

The challenging goal of this WP is to characterise by state-of-the-art high-throughput technologies the genomic, epigenomic, transcriptomic, microRNA and metabolomic landscapes together with circulating inflammatory mediators and extracellular vesicles profiles associated with outcome of decompensation of cirrhosis by re-analysing standardized biobank samples from 2,200 patients (40% men; 60% women). The main objectives of this WP are:

To set the legal and ethical terms for the efficient transfer of biological materials to each of the DECISION partners involved in sample processing

To discover genetic and epigenetic (methylation) signatures associated with outcome of decompensation of cirrhosis as well as response to treatment

To phenotype blood immune cells by whole-blood transcriptomics, interpreted in light of single-cell transcriptomics in a subgroup of patients, in relation with outcome of decompensation of cirrhosis as well as response to treatment

To investigate serum microRNA profiles associated with outcome of decompensation of cirrhosis as well as response to treatment

To investigate serum metabolites associated with outcome of decompensation of cirrhosis as well as response to treatment

To analyse plasma protein and lipid inflammatory (cytokines and eicosanoids) signatures associated with outcome of decompensation of cirrhosis as well as response to treatment

To capture plasma extracellular vesicle diversity, as markers of tissue damage and cell injury, associated with outcome of decompensation of cirrhosis as well as response to treatment
WP2 – Data Management

Lead: EF CLIF

The DECISION project will integrate detailed clinical data from 2,200 patients with more than 8,600 time points, from 3 prospective cohorts (CANONIC, PREDICT and ACLARA), with results of multi-omics analysis of available biobank samples performed in WP1. Data management, integration and analysis are therefore tasks of strategic importance. WP2 will provide a professional data management hub with the following specific objectives:

To harmonize and merge available clinical data-sets from three large international prospective cohorts (CANONIC, PREDICT and ACLARA) to be analysed by WP3

To combine this clinical dataset with the results of multi-omics analysis performed in WP1 in a joint data

To prepare and make the integrated secured central database available for systems approaches described in WP3
WP3 – Patient Stratification, Development of Prognostic and Response Tests and of new Combinatorial Therapies for Decompensated Cirrhosis using Systems Approaches

Lead: NBM-FSM

Heterogeneity in disease and drug response poses a major challenge in personalized medicine. It is necessary in order to decipher the optimal combinatorial therapy, to better understand the disease at a systems level. Therefore, in WP3 we will first combine all existing and newly acquired data (WP1-2) into a Systems Medicine framework. Second, we will use this framework during selection of optimal prognostic and response tests and new combinatorial therapies. WP3 consists of four objectives:

Identify the omic-derived information that extends clinical information and, as a result, develop a system-based description of decompensation of cirrhosis leading to ACLF and death, through multi-omics data integration analysis

Understand patient heterogeneity

Identify candidate prognostic tests and tests for response to combinatorial therapy

Identify candidate optimal combinatorial therapies for patients with decompensation of cirrhosis to prevent mortality
WP4 – Selection and Validation of Combinatorial Therapies using Preclinical Rat Models and Set-up of Prognostic Test and Response Test for Response to Combinatorial Therapy in Patients’ Samples

More info

Lead: GUF

The main objective of WP4 is to test the identified combinatorial therapies (WP3) pre-clinically in different models of decompensation of cirrhosis, prior to use in the clinical trial (WP5). Different rat models of acute decompensation of cirrhosis leading to ACLF have been proposed by the scientific community, but none of those models fully recapitulates the heterogeneity of the human disease. The second key objective of WP4 is, therefore, to refine existing animal (rat) models of decompensation of cirrhosis leading to ACLF. Moreover, two biomarkers will be developed: one predicting the treatment outcome of patients with acute decompensation of cirrhosis (prognostic test) and one serving as companion biomarkers to monitor treatment response for better stratification of treatment (test for response to combinatorial therapy). To achieve this, WP4 will pursue the following specific objectives:

To refine available and develop new models of acute decompensation of cirrhosis leading to ACLF, stratifying for gender and age

To validate in pre-clinical studies the combinatorial therapies identified in silico

To design one assay serving as biomarker of outcome of patients with acute decompensation of cirrhosis (prognostic test) and one serving as companion biomarkers to select patients responding to identified combinatorial therapy (test for response to combinatorial therapy)
WP5 – Clinical Proof-of-concept Phase II prospective randomized controlled Study

Lead: UNIBO

WP5 will conduct a clinical study in patients hospitalized for AD of cirrhosis in order to evaluate a novel combinatorial therapy as well as novel tests developed for predicting which patients with decompensated cirrhosis have a poor prognosis (prognostic test) and which patients are more likely to benefit from the selected combinatorial therapy (test for response).

To achieve this, WP5 will pursue the following specific objectives:

To conduct a proof-of-concept, phase II, multi-centre, open-label, randomized clinical trial (COMBAT trial) aiming to determine efficacy and safety of the combinatorial therapy selected according to the results of WP 1-4, having the highest chance of improving clinical outcome

To evaluate the novel tests developed in WP 1-4 by using the biological samples collected from patients enrolled in the COMBAT trial and in a parallel observational prospective study
WP6 – Ethics, Health and Socio-Economics

Lead: UB

DECISION is a multidisciplinary consortium including stakeholders of patients, academia, and industry and includes a broad and complex spectrum of methods and tasks. Therefore, several important ethical, legal, and socio-economic issues arise in this project, which will be addressed by this work package and can be summarized in the following main objectives of this WP:

To develop and implement ethical and legal issues linked to the collection, analysis, transfer, and use of human and animal data and samples

To develop and implement ethical and societal issues related to patients with decompensated cirrhosis

To determine the cost-effectiveness of these new strategies based on the WP5 clinical trial and disease modelling with the ultimate aim of decreasing the social and healthcare burden of decompensation of cirrhosis
WP7 – Dissemination, Communication, Exploitation, Guideline Development and Training

Lead: concentris

The objective of WP7 is the development of a communication strategy and dissemination plan aimed at potential stakeholders of the EU member states, namely patients, health care professionals, pharma and biotech companies, healthcare insurers, international professional networks, and the general public. The strategy will include the following specific aims:

To make DECISION known to all stakeholders

To disseminate the results to the scientific and medical community, healthcare, pharmaceutical and policy sectors, and the general public and foster interaction and exchange with patient organizations

To exploit and valorise the intellectual property rights (IPR) generated within WP1-5 and safeguard the sustainability of DECISION

To incorporate new knowledge on tests and combinatorial therapies into (inter)national clinical guidelines and inform patient communities of the benefits for the patients

To prepare the next generation of scientists in the field of liver research
WP8 – Project Management

Lead beneficiary: EF CLIF

Effective project management is a central element of successful research. This is because large research projects entail a lot of administrative work. The following objectives will be actively pursued by WP8:

To make DECISION achieve its objectives and to deliver in time, budget and quality its milestones and deliverables

To help the consortium abide by the regulations and contractual obligations according to the grant agreement, its annexes and the consortium agreement

To look after the project`s finances and to report them properly to the EC

To establish a communication infrastructure which enables the partners to communicate efficiently and to stay connected for the run-time of the project

To preserve the rights of the partners regarding intellectual property and to act as a mediator in case of disputes
