NEPHSTROM for Diabetic Kidney Disease
Study Details
Study Description
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).

Outcome Measures
Primary Outcome Measures
- 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 Outcome Measures
- 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.
- 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).]
- 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.
- 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 EQ-5D-5L questionnaire.
- 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.

-
Other concomitant disease or conditions in the opinion of the investigator that are likely to pose risk to the patient and that would render the patient unsuitable for participation or that could impair patient safety or ability to participate in the study, such as active malignancy;

-
Positive screening test for clinically significant anti-HLA antibodies. An initial antibody screening with Luminex® multi-antigen beads to detect class I and class II MHC antibodies followed by a Luminex single antigen bead assay to determine the specificity of any antibody detected. Potential study subjects with positive screening for any clinically significant anti-HLA antibody will be excluded and will not be eligible to participate in the NEPHSTROM clinical study (MFI>1500);
-

Women of childbearing potential can only be included in the study if a pregnancy test is negative at the screening visit (V1) and at baseline visit (V2) if they agree to use adequate contraception. Adequate contraception is defined as any combination of at least two effective methods of birth control, of which at least one is a physical barrier (e.g. condoms with hormonal contraception or implants or combined oral contraceptives, certain intrauterine devices). Women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate) or 6 months of spontaneous amenorrhea with serum FSH levels > 40 mIU/mL or have had surgical treatment such as bilateral tubal ligation, bilateral oophorectomy, or hysterectomy.
-

-
Participation in other investigational medicinal product (IMP) trials within 30 days before the inclusion or concurrent to this study (18 month follow-up);
