19The purposes of this study are to assess safety, efficacy, and subject satisfaction of EPODURE Biopump (an autologous dermal biopump capable of sustained secretion of therapeutic EPO in the body, using a small tissue explant from the patient's own skin) treatment in Chronic Kidney Disease (CKD) patients over a period of up to six (6) months.
Anemia, is a common complication of chronic kidney disease (CKD) resulting from insufficient production of the hormone erythropoietin by the damaged kidney leading to a decrease in red blood cells production by the bone marrow.
Replacement therapy with recombinant human erythropoietin can effectively correct anemia in patients. However, despite the availability of recombinant human erythropoietin for more than a decade for use in CKD patients, two thirds of patients initiating dialysis have a hematocrit less than 30%, and three fourths have a hemoglobin (Hb) less than 11 g/dL the level recommended by the National Kidney Foundation Kidney Disease Outcome Quality Initiative. Treatment with recombinant human erythropoietin typically involves subcutaneous (SC) administration at regular intervals followed by frequent laboratory tests to monitor hemoglobin concentration. There is a need to provide an significantly improved care in this area using a sustained therapy approach.
EPODURE, is an autologous dermal biopump capable of sustained secretion of therapeutic EPO in the body, using a small tissue explant from the patient's own skin. The EPODURE biopump is harvested directly from the patient's dermis under local anesthetic. EPODURE Biopumps, produced by ex vivo transduction of MOs with Helper Dependent Adenoviral EPO vectors (HDAd-EPO), expresses and secretes EPO. The EPODURE Biopump is subsequently implanted subcutaneously back to the patient in order to provide continuous delivery of a known amount of EPO.
Subjects will undergo similar study procedures and evaluations; however each dosage group will receive a different targeted dose of EPO delivered via EPODURE Biopump
Cohort 1 (Low Dose group) 18-25 IU/kg/day
Cohort 2 (Intermediate Dose group): 35-45 IU/kg/day
Cohort 3 (High Dose group): 55-65 IU/kg/day
Inclusion Criteria: Adult male or female subjects between 18 to 75 years of age at the time of screening visit. Subject with Anemia of Chronic Renal Failure CKD stage 3-4. estimated GFR of 15-60 ml/min with Female: Hb < 10 g%, Male: Hb < 11 g%. Chronic renal failure subjects who are EPO naïve or have been off EPO or similar Erythropoietic drugs for more than four (4) weeks. Subjects who are clinically stable. Adequate iron stores (transferrin saturation ≥ 20.0% and ferritin ≥100 ng/ml). Subjects who receive anti-coagulation treatment may be enrolled provided anti-coagulation treatment can be discontinued two weeks prior to the harvesting visit. INR level must be within normal range (0.9 - 1.5). Signed written informed consent to participate in the study by subject Exclusion Criteria: Uncontrolled hypertension (defined as diastolic blood pressure > 110 mmHg or systolic blood pressure > 180 mmHg during screening). Congestive heart failure (New York Heart Association functional class III or IV). Grand mal seizures within 2 years of the screening visit. Clinical evidence of severe hyperparathyroidism as defined by PTH levels of > 10 times the upper normal limits. Major surgery within 12 weeks of the screening visit. Systemic hematologic diseases (e.g., sickle cell anemia, myelodysplastic syndromes, hematologic malignancy, myeloma, hemolytic anemia). Current systemic infection, active inflammatory disease, or malignancy under treatment. Known positivity for HIV antibody. Subjects known to have tested positive at any time in the past for antibodies to erythropoietic proteins. Subject has history of malignancy within the past 2 years prior to the screening visit, with the exception of basal cell carcinoma. Subjects with other concurrent severe and/or uncontrolled medical condition which could compromise participation in the study (i.e. active infection, uncontrolled diabetes, uncontrolled hypertension, congestive cardiac failure, unstable angina, ventricular arrhythmias, active ischemic heart disease, myocardial infarction within six months, uncompensated cirrhosis, active upper GI tract ulceration). Subject is currently enrolled in, or has not yet completed a period of at least 30 days since ending other investigational device or drug trial(s). Psychiatric, addictive, or any other disorder that compromises ability to give truly informed consent for participation in this study. Female subjects of child-bearing potential and not having undergone permanent sterilization procedures. Pregnant and lactating female subjects. Chronic alcoholic or drug abuse subjects. Steroid or other immunosuppressive treatment. Subjects unwilling or unable to comply with the study procedures.
