Brief summary
The study will investigate, primarily, the safety, feasibility and tolerability and, secondarily, the preliminary efficacy of an allogeneic bone marrow-derived Mesenchymal Stromal Cell (MSC) therapy (ORBCEL-M) in study subjects with type 2 diabetes (T2D) and progressive diabetic kidney disease (DKD).
Interventions
Cells will be administered intravenously at 3 different doses (80, 160, or 240 x 10\^6, fixed dose) over 10-20 minutes. Volume total of fluid infused: 40 ml
Volume total of fluid infused: 40 ml

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number and severity of all pre-specified infusion-associated events and the overall number and frequency of adverse events. | Changes from baseline to study completion, up to 18 months after cell or placebo infusion. | At each visit overall clinical condition of the patient will be evaluated and any adverse event wil be recorded. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Urinary Albumin/Creatinine Ratio (ACR) | Changes from baseline at 6 months and then every six months to study completion,up to 18 months after cell or placebo infusion. | ACR will be measured on spot morning urine samples. |
| Urinary albumin excretion (UAE). | Changes from baseline at 6 months and then every six months to study completion,up to 18 months after cell or placebo infusion. | UAE will be measured on 24h urine samples using standardized methods. |
| Fasting blood glucose (target <126mg/dL) | Proportion of study participants within target range (<126mg/dL) at baseline and at each time point (day 1, day 7, month 1,3,6,12,18 after cell or placebo infusion). | — |
| HbA1c (target <75mmol/mol or <9%) | Proportion of study participants within target range (<75mmol/mol or <9%) at baseline and at each time point (day 1, day 7, month 1,3,6,12,18 after cell or placebo infusion). | — |
| Total cholesterol (target <200 mg/dl) | Proportion of study participants within target range (<200 mg/dl) at baseline and at each time point (day 1, day 7, month 1,3,6,12,18 after cell or placebo infusion). | — |
| LDL cholesterol (target <100 mg/dl) | Proportion of study participants within target range (<100 mg/dl) at baseline and at each time point (day 1, day 7, month 1,3,6,12,18 after cell or placebo infusion). | — |
| Triglycerides (target <170 mg/dl) | Proportion of study participants within target range (<170 mg/dl) at baseline and at each time point (day 1, day 7, month 1,3,6,12,18 after cell or placebo infusion). | — |
| Arterial blood pressure (the target value <130/80 mmHg) | Proportion of study participants within target range (<130/80 mmHg)at baseline and at each time point (day 1, day 7, month 1,3,6,12,18 after cell or placebo infusion). | — |
| Glomerular filtration rate (GFR) | Changes from baseline up to 18 months after cell or placebo infusion. | GFR will be measured by plasma clearance of unlabelled exogenous marker Iohexol and estimated by CKD-EPI and MDRD equations. |
| Anti-HLA antibody development | Changes from baseline to 3,12 and 18 months after cell or placebo infusion. | — |
| Inflammation and fibrosis related soluble mediators | Changes from baseline to 7 days, 1,6,12 and 18 months after cell or placebo infusion. | Blood and urine bio-chip-based multiplex assay |
| Serum/plasma concentrations (pg/ml) of biomarkers of inflammation. | Changes from baseline to 7 days, 1,6,12 and 18 months after cell or placebo infusion. | Biomarkers will include sTNFR1, sTNFR2, Il-6,TNF-alfa, IL-1beta, MCP-1 (CCL2), IL-8, FGF21. |
| Serum/plasma concentrations (ng/ml) of biomarkers of CKD progression. | Changes from baseline to 7 days, 1,6,12 and 18 months after cell or placebo infusion. | Biomarkers will include Cystatin C, NGAL, Adiponectin, Leptin. |
| Urine concentrations (pg/ml adjusted to urine creatinine concentration) of biomarkers of inflammation. | Changes from baseline to 7 days, 1,6,12 and 18 months after cell or placebo infusion. | Biomarkers will include sTNFR1, sTNFR2, Il-6,TNF-alfa, IL-1beta, MCP-1 (CCL2), IL-8. |
| Proportion/total number of circulating T cells, B cells, NK cells, monocytes, dendritic cells | Changes from baseline to 7 days, 1,6,12 and 18 months after cell or placebo infusion. | — |
| Cost-effectiveness of cell therapy | Changes from baseline to 1,3,6,12 and 18 months after cell or placebo infusion. | Cost-effectiveness of cell therapy will be evaluated by providing the patients with a healthcare resource diary. |
| Quality of life | Changes from baseline to 1,3,6,12 and 18 months after cell or placebo infusion. | Quality of life will be evaluated by the administration of SF36 questionnaire. |
