About

The purpose of this study is to assess the safety, efficacy, and durability of up to two REACT injections delivered percutaneously into biopsied and non-biopsied contralateral kidneys on renal function progression in two different cohorts of subjects with T1DM or T2DM and CKD.

Full description

The objective of this study is to assess the safety, efficacy, and durability of up to two REACT injections delivered percutaneously into biopsied and non-biopsied contralateral kidneys on renal function progression in two different cohorts of subjects with T1DM or T2DM and CKD:

• Cohort 1: Two scheduled REACT injections given 3 months (+60 days) with at least 18- month follow-up
• Cohort 2: One scheduled REACT injection with a possible second REACT injection, no less than 3 months after the first one, within 30 days (+30 days) of meeting a renal function redose trigger (triggered up to 15 months following the first REACT injection).

Both cohorts will be followed for 18 months after the final REACT injection. If a Cohort 2 subject does not meet a trigger, the subject will be followed for at least 18 months after the first injection.

Enrollment: 53 patients

Sex: All

Ages: 30 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Male or female aged 30 to 80 years, inclusive, on the date informed consent is signed.
2. Clinical diagnosis of T1DM or T2DM, controlled per institutional standard of care.
3. The subject has a clinical diagnosis of diabetic nephropathy as the underlying cause of renal disease (diagnosis does not have to be confirmed via renal biopsy).
4. The subject has a serum glycosylated hemoglobin (HbA1c) level less than 10% at the Screening Visit.
5. The subject has a documented clinical diagnosis of an eGFR between 20 and 50 mL/min/1.73m² inclusive not requiring renal dialysis.

Exclusion criteria

1. The subject has a history of renal transplantation.

2. The subject has a mean systolic blood pressure greater than or equal to 140 mmHg and/or mean diastolic blood pressure greater than or equal to 90 mmHg at screening.

   Subjects with blood pressure outside of this range prior to biopsy/injection may continue if approved by the Medical Monitor.

3. The subject has hemoglobin levels less than 10 g/dL and is not responsive to the standard medical intervention for CKD-related anemia prior to randomization.
