From Nature to Bedside- Algae Based Bio Compound for Prevention and Treatment of Inflammation, Pain and IBD

Study Overview
=================
Brief Summary
-----------------
This study is part of the project funded by the Horizon2020 program for establishing the consortium Algae4IBD (https://algae4ibd.eu/), where OSR participates as a partner. It aims to promote the implementation of the European Crohn's and Colitis Organization (ECCO/FECCO) Directive and the benefit of the Inflammatory Bowel Disease (IBD) patient's wellness by finding innovative algae based novel small molecule therapeutics. A systemic approach to eco-innovation is adopted to create interconnections between sectors, value chains, natural resources, and relevant societal stewards. To this end, the consortium has set specific objectives to achieve holistic innovations, including technical, economic, health, and social factors that all work in concert. IBD included Crohn's disease and ulcerative colitis. It is a class of chronic inflammatory disorders with complex pathogenesis. Despite the lack of a full understanding of its etiogenesis, many anti-inflammatory treatments have been developed over the last decades. However, not all patients may benefit from these treatments and some of them are refractory to the current therapies or experience relapse of the disease. Therefore, there is still an urgent need to find an innovative line of interventions for ameliorating these patients' overall quality of life. Algae4IBD consortium will form a bridge between innovation and market demands to prevent and treat inflammation, pain, and IBD. Bioactive molecule/compounds extracts from microalgae, cyanobacteria, and macro-algae (MiaCyMa) are an inexhaustible untapped natural source for products destined for IBD prevention and treatment (inflammation, pain, and the disease process associated with the gut's microbiome). The natural source potential is still more promising when considering extremophile strains for excellent metabolism systems. Moreover, the production of the natural source of biological materials should be sustainable. Indeed, the non-genetically modified organisms (GMO cultures offer numerous advantages such as reduced requirements of fresh water and land (no arable land is required), drastic reduction of nitrogen sources, and potential environmental threats. Algae4IBD concept will include a multi-step screening approach and feedback loops across the project steps to achieve its goals. Specifically, OSR is in charge with work package (WP) 4, task 4.4, which aims to characterize the activity of plant cell (algae) extracts named in this proposal as natural compounds of algae provided by the consortium in ex-vivo models, using bioptic samples derived from patients with IBD (patients with ulcerative colitis (UC) and Crohn's disease (CD)), comparing them to samples derived from patients without UC and CD.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Ulcerative Colitis (UC)<br>subjects undergoing endoscopy and biopsies collection per standard of care adult patients ≥18 and <60 years clinical and endoscopic evaluation (Mayo score≥2) | Procedure: Additional biopsies collection<br>* We will recruit only subjects (UC, CD and NO-UC/CD) scheduled for the endoscopy and biopsies-collection according to the usual clinical practice. During the endoscopy we will collect 6 additional biopsies.<br>|
| Crohn's Disease (CD)<br>subjects undergoing endoscopy and biopsies collection per standard of care adult patients ≥18 and <60 years clinical and endoscopic evaluation (Harvey-Bradshaw score ≥5 and overall simplified endoscopic score (SES-CD) >2) | Procedure: Additional biopsies collection<br>* We will recruit only subjects (UC, CD and NO-UC/CD) scheduled for the endoscopy and biopsies-collection according to the usual clinical practice. During the endoscopy we will collect 6 additional biopsies.<br>|
| NO UC/CD<br>subjects undergoing endoscopy and biopsies collection (≥18 and <60 years) according to the normal clinical practice (as patients undergoing cancer surveillance, irritable bowel syndrome (IBS), diarrhea) subjects not affected by UC or CD according to the previously reported clinical and endoscopic evaluation criteria | Procedure: Additional biopsies collection<br>* We will recruit only subjects (UC, CD and NO-UC/CD) scheduled for the endoscopy and biopsies-collection according to the usual clinical practice.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To evaluate the response of intestinal mucosa samples to treatments with natural compounds derived from algae in terms of release of pro-inflammatory factors (1), transcriptomics, metatranscriptomics (2) and lipidomics analysis (3) | Release of pro-inflammatory cytokines using ELISA RNA-Seq-generated FASTQ reads from human colons will be quality filtered and adaptor trimmed with NCBI fastq-dump. Lipids detected by LC-MS/MS will be classified based on their precursors, and, in parallel, based on their metabolic pathways. By multi-omic factor analysis we will integrate these data with the patients' clinical parameters, correlating among each other in parallel and giving one single output (outcome measure, in our case, multiomic factor) explaining how the different omic layers are assigned simultaneously to specific clinical characteristics, thus resulting as associated with, or predictive of, the clinical progression of IBD. | 30 months |
