Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Neo-Kidney Augment

Arm Description

NKA is made from expanded autologous selected renal cells (SRC) obtained from the patient's kidney biopsy. To manufacture NKA, kidney biopsy tissue from each enrolled patient will be sent to RegenMedTX, LLC, where renal cells will be expanded and SRC selected. SRC will be formulated in a gelatin based hydrogel at a concentration of 100 x 106 cells/mL, packaged in a 10 mL syringe, and shipped to the clinical site for use.

Outcomes

Primary Outcome Measures

Procedure and/or Product Related Serious Adverse Events (AE's) Through 12 Months Following the Final NKA Implantation
Procedure and/or product related adverse events (AE's) through 12 months following the final NKA implantation, as measured by AE reporting.
Serial Estimation of Glomerular Filtration Rate (GFR) Through 6 Months Following the Final Cell Implantation, as Measured by Serial Serum Creatinine.
The patient's serum creatinine was measured using a blood test at predetermined intervals and used to estimate the glomerular filtration rate as an indication of overall renal function.

Secondary Outcome Measures

Renal-specific Laboratory Assessments Through 12 Months Following the Last NKA Implantation Under This Protocol.
Renal-specific laboratory assessments through 12 months following the last NKA implantation under this protocol, whether first or second, as measured by renal specific biomarkers.

Brief Summary
A Phase II, Open-Label Safety and Efficacy Study of an Autologous Neo-Kidney Augment (NKA) in Patients With Type 2 Diabetes and Chronic Kidney Disease (RMTX-CL001). NKA is made from expanded autologous selected renal cells (SRC) obtained from the patient's kidney biopsy. All enrolled subjects will be treated with up to two injections of NKA at least 6 months apart.
Detailed Description
A Phase II, Open-Label Safety and Efficacy Study of an Autologous Neo-Kidney Augment (NKA) in Patients With Type 2 Diabetes and Chronic Kidney Disease (RMTX-CL001). This is a Multi-center, prospective, open-label, single-group study. NKA is made from expanded autologous selected renal cells (SRC) obtained from the patient's kidney biopsy. To manufacture NKA, kidney biopsy tissue from each enrolled patient will be sent to RegenMedTX, LLC, where renal cells will be expanded and SRC selected. SRC will be formulated in a gelatin based hydrogel at a concentration of 100 x 106 cells/mL, packaged in a 10 mL syringe, and shipped to the clinical site for use. All enrolled subjects will be treated with up to two injections of NKA at least 6 months apart. Up to 30 subjects undergoing NKA injection will be enrolled into the study. Patients who have received a single injection of NKA under previous research protocols may enroll in this clinical trial to receive a single additional implantation. Patients who have never received an NKA injection may enroll in this clinical trial for up to a total of two (2) NKA injections, temporally spaced at least 6 months apart. All biopsies are to be taken from a single kidney, and all NKA injections are to be given into the kidney that was biopsied. Patients who complete screening procedures satisfying all I/E criteria will be enrolled into the study immediately prior to the injection. Patients who do not meet all criteria before injection will be considered screen failures. Once a patient has been injected, the patient will have completed treatment and every effort should be made to ensure the patient completes all follow-up visits. Injection dates for the first 3 patients receiving their second NKA injection will be staggered by a minimum of 3 week intervals to allow for assessment of acute adverse events and other safety parameters by a Data Safety Monitoring Board (DSMB). At the completion of the follow-up visits, patients will continue in a long-term observational follow-up period. Patients will be followed for a total of 36 months following the last NKA injection under this protocol, whether the first or second injection.
