Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Patients with estimated Glomerular Filtration Rate 15 - 60 mL/min at Screening due to intrinsic or "medical" renal disease (such as nephropathy due to type-2 diabetes, nephrosclerosis or chronic glomerulonephritis).
3. Mean systolic blood pressure between 105 and 160 mmHg, inclusive; mean diastolic blood pressure must be ≤90 mmHg. Patients with blood pressure outside of this range prior to implant, may be implanted if approved by the Medical Monitor.
4. Ongoing treatment with an angiotensin converting enzyme inhibitor and/or angiontensin receptor blocker, initiated at least 6 weeks prior to screening.
5. Minimum 3 month medical history of CKD progression as assessed by laboratory values.
6. Willing and able to refrain from use of NSAIDs (including aspirin) and clopidogrel for 10 days before and 10 days after biopsy and implant.
7. Willing and able to cooperate with all aspects of the study.
8. Willing and able to give signed informed consent. -
Exclusion Criteria
2. History of a renal transplant.
3. HbA1c ≥ 104 mmol/mol IFCC at Screening.
4. BMI \<18.5 kg/m2 or \>35 kg/m2 at Screening.
5. Abnormal coagulation status as measured by APTT, INR, fibrinogen and/or platelet count.
6. Ineligible for an MRI or renal scintigraphy (e.g. due to hypersensitivity or allergy) study based on the Karolinska University Hospital guidelines.
7. Clinically significant infection requiring parenteral antibiotics within 6 weeks of biopsy or implantation.
8. CKD due to polycystic kidney disease, other renal structural abnormalities, myeloma kidney, history of nephroblastoma, post-streptococcal glomerulonephritis, pre- or postrenal component of CKD, and genetically based renal disease (e.g. Podocin mutations, renal agenesis).
9. Patients with small (\< 10 cm) kidneys or only one kidney; patients with a history of highly echogenic kidneys. Patients with an average width of kidney cortex \< 1.0 cm as estimated by MRI. Patients whose left kidney would not be acceptable for biopsy/implant as assessed by the Investigator based on results from screening procedures.
10. Female subjects who are pregnant, lactating (breast feeding) or planning a pregnancy during the course of the study, or who are of child bearing potential and not using a highly effective method of birth control (including sexual abstinence). A highly effective method of birth control is defined as one that results in a low failure rate (i.e. less than 1 percent per year) when used consistently and correctly, such as implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence, or a vasectomized partner. Subjects must be willing to continue birth control methods throughout the course of the study.
11. History of cancer within the past 5 years (excluding non-melanoma skin cancer and carcinoma in situ of the cervix) or a condition highly likely to transform into malignancy during the course of the study.
12. Life expectancy of less than 2 years.
13. Any contraindication or known anaphylactic or severe systemic reaction to either human blood products or materials of animal (bovine, porcine) origin or anesthetic agents.
14. Positive results for any of the following (per Commission Directive 2006/17/EC) at Screening and Biopsy:
1. Viral Nucleic Acid Testing: Human Immunodeficiency Virus (HIV) 1 and 2 RNA, Hepatitis B Virus (HBV) DNA, Hepatitis C Virus (HCV) RNA
2. Viral Protein Testing: HBV surface antigen (HBsAg)
3. Viral Antibody Testing: Anti-HIV 1 and 2, Anti-HBV core antigen (Anti HBc), Anti-HCV antibody.
4. Confirmed active infection with Treponema pallidum.
15. Subjects with active tuberculosis (TB) requiring treatment in the past 3 years.
16. Immunocompromised subjects or patients receiving immunosuppressive agents (including patients treated for chronic glomerulonephritis) within 3 months of biopsy. \[Note: inhaled corticosteroids and chronic low-dose corticosteroids \[≤ 7.5mg per day\] are permitted as are brief pulsed corticosteroids for intermittent symptoms (e.g. asthma).\]
17. Subjects with uncontrolled diabetes (defined as metabolically unstable by the PI), incapacitating cardiac and/or pulmonary disorders.
18. History of active alcohol and/or drug abuse that in the investigator's assessment would impair the subject's ability to comply with the protocol.
19. Subjects with an albumin value \< 25 g/L, and albumin/creatinine ratio greater than 3500mg/g at Screening or prior to Biopsy.
20. Patients with clinically significant hepatic disease (ALAT or ASAT \> 5.0 x ULN) at Screening.
21. Patients with bleeding disorders or patients taking Coumarins (e.g.,Warfarin).
22. Any circumstance in which the investigator deems participation in the study is not in the subject's best interest.
23. Use of any investigational product (drug, biologic, or device) within 5 half-lives (drug, biologic) or 3 months, whichever is longer, without receiving prior written consent of the Medical Monitor.-
