E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to assess the safety and efficacy of NKA injected in one recipient kidney and determine if two injections of NKA provide stabilization of renal function. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objective of the study is to assess the safety and tolerability of NKA administration by assessing renal-specific adverse events over a 12 month period following a patient’s first NKA injection. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male and female subjects, age 30 to 70 years on the date of informed consent. 2. Patients with type 2 diabetes mellitus (T2DM). 3. Patients with a well-established diagnosis of diabetic nephropathy as the underlying cause of their renal disease. 4. At screening, patients not previously injected with NKA with CKD defined as a GFR of 20 – 50 mL/min/1.73m2 inclusive. Patients previously treated with a single NKA injection with eGFR 15 to 60 mL/min may also enroll in this clinical trial. 5. Microalbuminuria that cannot be explained by an alternative diagnosis. Microalbuminuria is defined as urinary albumin-creatinine ratio (UACR) ≥ 30 mg/g or urine albumin excretion ≥ 30 mg/day on 24 hour urine collection. 6. Prior to biopsy, systolic blood pressure between 105 and 140 mmHg (inclusive) and diastolic blood pressure ≤90 mmHg. 7. Ongoing and stable treatment with ACEI or ARB initiated at least 8 weeks prior to enrollment. Treatment must be stable for the 6 weeks immediately prior to injection. Stable treatment is defined as dose adjustment to no less than ½ of the current dosage and no more than 2X the current dosage over the 6 week period immediately prior to injection; dose interruptions of up to 7 days due to medical necessity are allowed. Patients who are intolerant to ACEI or ARBs may be included as long as they have stable BP within the acceptable limits. 8. Minimum of 2 measurements of eGFR or sCr taken at least 3 months apart (prior to screening) and within the previous 12 months to define the rate of progression of CKD. The patient should have sufficient historical data to provide a reasonable estimate of the rate of progression of CKD as determined following consultation with the Medical Monitor (to insure sufficient data is available). In addition, the rate of progression of CKD must be consistent over time. There is no defined rate of progression that is required to qualify for inclusion. 9. Willing and able to refrain from use of NSAIDs (including aspirin) and clopidogrel, prasugrel, or other platelet inhibitors peri-procedure (i.e., before and after both the biopsy and injection). The wash-out period before and after each procedure should be 7 days. Willing and able to refrain from use of fish oil and dipryridamole for 7 days before and 7 days after each procedure. 10. Willing and able to cooperate with all aspects of the study. 11. Willing and able to give signed informed consent. |
|
E.4 | Principal exclusion criteria |
1. Type 1 diabetes mellitus (DM). 2. History of a renal transplant. 3. HbA1c > 10% at Screening. Patients with HbA1c > 8% at the time of screening should be offered diabetic teaching and advised to consult their primary physicians for further diabetic management. 4. Hemoglobin levels < 9 g/dL prior to injection. Hemoglobin levels should be measured within 48 hours before the procedure or per site standard practice. 5. Known allergy to kanamycin or structurally similar aminoglycoside antibiotics (as kanamycin is used during manufacture of NKA). 6. Abnormal coagulation status as measured by APTT, INR, and/or platelet count at Screening. 7. Not a good candidate for the injection procedure (based on the assessment of the surgeon who will be performing the injection) including patients who are morbidly obese, have excessive fat surrounding the kidney, have BMI > 45, or who are otherwise at excessive risk for serious complications. 8. Clinically significant infection requiring parenteral antibiotics within 6 weeks of injection. 9. Patients with small kidneys (average size < 9 cm) or only one kidney, as assessed by MRI or renal US at screening or if previously done within 1 year of screening. 10. Patients with a rapid decline in renal function over the last 3 months prior to injection or acute kidney injury. 11. Patients with any of the following conditions prior to injection: renal tumors, polycystic kidney disease, renal cysts or other anatomic abnormalities that would interfere with injection procedure (e.g., cysts in the pathway of the injection), hydronephrosis, skin infection over proposed injection sites, or evidence of a urinary tract infection. 12. 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. 13. History of cancer within the past 3 years (excluding non-melanoma skin cancer and carcinoma in situ of the cervix). 14. Life expectancy of less than 2 years. 15. Any contraindication or known anaphylactic or severe systemic reaction to either human blood products or materials of animal (bovine, porcine) origin or anesthetic agents. 16. Positive for Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), or Hepatitis C Virus (HCV) assessed at the Screening Visit. 17. Subjects with active tuberculosis (TB) requiring treatment in the past 3 years. 18. Immunocompromised subjects or patients receiving immunosuppressive agents (including patients treated for chronic glomerulonephritis) within 3 months of injection. [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).] 19. Subjects with uncontrolled diabetes (defined as metabolically unstable by the PI), or with incapacitating cardiac and/or pulmonary disorders. 20. 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. 21. Patients with clinically significant hepatic disease (ALT or AST > 3.0 x ULN) at Screening. 22. Patients with bleeding disorders that would, in the opinion of the Investigator, interfere with the performance of study procedures; patients taking coumarins (e.g. Warfarin) or other anticoagulants (e.g. enoxaparin or direct thrombin inhibitors). 23. Any circumstance in which the investigator deems participation in the study is not in the subject’s best interest. 24. Use of any investigational product within 3 months of the injection without receiving prior written consent of the Medical Monitor. |
