Clinical Trial Summary

The natural history of Systemic lupus erythematosus (SLE) is characterized by relapses or flares alternated with periods of remission. Flares are associated with accrual of organ damage independently of other risk factors, both contributing to a considerable morbidity. No useful biomarker is currently available to predict which patients with a quiescent disease are at risk of flare. The 3TR project (funded by the Innovative Medicines Initiative 2 Joint Undertaking under grant agreement No 831434, and supported by European Union's Horizon 2020 research and innovation programme and EFPIA) is a transdisciplinary consortium that primary aims at identifying biosignatures as predictors of response and non-response to therapy in seven different autoimmune, allergic and inflammatory diseases, including SLE. 3TR will perform a longitudinal multi-dimensional molecular analysis in patients with these diseases. A molecular profiling approach is a modern and innovative way to investigate and stratify heterogeneous diseases on the basis of their common biomolecular pathways. The main hypothesis of the 3TR project is that data obtained from multiomic analysis across the seven different diseases will identify shared biological pathways that better predict the response or non-response to therapy despite their differences in terms of clinical phenotypes and pathogenetic mechanisms. Therefore patients from multiple European centers participating in 3TR will be recruited for a longitudinal clinical follow-up and collections of several samples that will be used to perform multi-omic analysis.


Description:

The study will be carried out in the framework of the IMI2 (innovative medicine initiative) and EFPIA (European Federation of Pharmaceutical Industries and Associations)-funded 3TR (Taxonomy, Treatment, Targets and Remission) project. The programme is supported by the European Union's Horizon 2020 research and innovation programme. 3TR is funded under the grant agreement No 831434 and it runs from 2019 to 2026. 3TR is a transdisciplinary consortium that aims to perform a longitudinal multi-dimensional molecular analysis in patients with autoimmune, allergic and inflammatory diseases. A molecular profiling approach is a modern and innovative way to investigate and stratify heterogeneous diseases on the basis of their common biomolecular pathways. The main hypothesis of the 3TR project is that data obtained from multiomic analysis across seven different diseases, including SLE, will identify shared biological pathways that better predict the response or non-response to therapy despite their differences in terms of clinical phenotypes and pathogenetic mechanisms. Patients from multiple European centers participating in 3TR will be recruited for a longitudinal clinical follow-up and collections of several samples that will be used to perform multi-omic analysis. Several innovations are expected within the 3TR project to increase the knowledge of pathogenetic mechanisms underlying the clinical phenotypes in SLE, and to unravel, in the complexity of SLE biomolecular heterogeneity, the pathways of response or non-response to treatment, as well as, at an earlier stage, the processes that may lead to disease flare. These insights could ultimately allow the possibility to effectively practice prevention and counselling, to adopt measures of personalized treatment or to perform drug repurposing using the knowledge gained from the SLE studies and the studies on other diseases within the 3TR project. Moreover, the impact of the COVID-19 viral pandemic will be implemented in our research. More specifically, we will investigate the impact of the presence of anti-SARS-CoV-2 antibodies of different isotypes (IgA, IgG, IgM) on the development of flare, as well as on the response or non-response to immunomodulatory therapy. To implement the strategy, a two-step research has been designed, and comprises: 1. The flare biomarker study (3TR SLE 1) is considered a "feeding" phase before the main part. Patients who meet the inclusion criteria for 3TR SLE 2 will be proposed to participate in the second study. 2. The response biomarker study (3TR SLE 2), which is a prospective study (main part). The present protocol relates to the flare biomarker study (3TR SLE 1).

Intervention

Biological:
Blood sample
- Total volume of blood (on each sampling occasion): 54,5mL. Whole blood will be collected in EDTA, 1 tube of 10 mL for DNA (genotyping, methylation arrays; at baseline for genotyping and at EOS visit for methylation arrays). From this, an aliquot of 0.5 mL for baseline cell numbers (cell proportions, CyTOF/flow cytometry) at all time points; capture of leukocytes for blood single cell RNA seq. at all time points and 5 mL for cell stimulations for cell metabolome (C13 to be added), and 1 tube of 10 mL for cell stimulations (CyTOF) at baseline.Tempus tube: 1 tube of 3 mL for RNA, 1 tube of 3mL for whole blood RNA seq.; to be taken at all time points. Plasma will be obtained and aliquoted from these tubes; to be obtained at all time points. Serum: 2 tubes of 10 mL without anticoagulant for measurements of anti-drug antibodies, hydroxychloroquine levels, cytokines and analytes, proteome, and autoantibodies; to be taken at all time points.
Urine sample
- Urine: 100 mL which will be centrifuged. The pellet will be frozen, and the urine supernatant will be aliquoted;
Saliva sample
- Saliva: will be collect in special container for saliva microbiome and methylation;
Stood sample
- Stool: One sample for microbiome to be sent to the biobank, frozen at -80 °C
Procedure:
Tissue sample
- Tissue samples for organ-specific manifestations: Kidney tissue in lupus nephritis: one small fragment of the fresh kidney biopsy will be stored in a 10% dimethyl sulfoxide (DMSO) solution (slow freezing to -80 °C) until shipment. Skin tissue (at selected centers) from inflamed lesion and non-inflamed skin from the gluteal region will be obtained through punch biopsy and stored in a 10% dimethyl sulfoxide (DMSO) solution (slow freezing to -80 °C) until shipment. Synovial tissue (at selected centers) will be obtained through ultrasound-directed arthroscopy and stored in a 10% dimethyl sulfoxide (DMSO) solution (slow freezing to -80 °C) until shipment. Aspirate from swollen lymph nodes (at selected centers) will be obtained and stored in a 10% dimethyl sulfoxide (DMSO) solution (slow freezing to -80 °C) until shipment.
