Outcome Measures
Primary Outcomes (2)
Surrogate / Intermediate Efficacy Endpoint -eGFR Slope
The difference in annualized eGFR slope between the rilparencel and sham cohorts (approximately 18 months after the 135th participant receives their first injection/sham) using the 2021 Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) serum creatinine-based equation.
18 months after the 135th participant receives their first injection / sham.
Clinical Endpoint
The time from first injection to the earliest of: * At least 40% reduction in eGFR, sustained for 30 days, OR * eGFR \<15 mL/min/1.73m² with corresponding two-sided 95% CI, sustained for 30 days and/or chronic dialysis, and/or kidney transplant OR * Renal or cardiovascular death
From date of first injection until the date of first event: 40% reduction in eGFR, eGFR < 15 mL/min/1.73m² and/or chronic dialysis, and or renal transplant or date of renal or cardiovascular death, whichever came first, assessed up to 94 months.
Secondary Outcomes (5)
Secondary Endpoint: Time from first injection to at least a 40% reduction in eGFR sustained for 30 days.
From date of first injection until the date of 40% reduction in eGFR assessed up to 94 months.
Secondary Endpoint: Time from first injection to eGFR < 15 mL/min/1.73m² sustained for 30 days and/or chronic dialysis, and/or kidney transplant.
From date of first injection until the date of eGFR < 15 mL/min/1.73m² assessed up to 94 months.
Secondary Endpoint: All-cause mortality.
From date of first injection to all-cause mortality assessed up to 94 months.
Secondary Endpoint: Kidney Disease Quality of Life Changes

Study Arms (2)
Sham Procedure
SHAM COMPARATORParticipants randomized to the Sham Comparator arm will have 2 sham procedures.
Experimental (REACT/rilparencel injections)
EXPERIMENTALParticipants randomized to the experimental arm will receive 2 injections of REACT/ rilparencel.
Interventions
Participants will have sham procedures that simulate real biopsy and injection procedure. No tissue is taken during biopsy and nothing is injected into kidney. The 2 injection/ sham procedures will occur approximately 12 weeks apart.
Participants will have a kidney biopsy followed approximately12 weeks later with a rilparencel injection into the biopsied kidney, then, approximately 12 weeks later a rilparencel injection into their contralateral kidney.
Eligibility Criteria
You may qualify if:
- The participant is male or female, 30 to 80 years of age on the date of informed consent.
- Documented diagnosis of type 2 diabetes mellitus (T2DM) and chronic kidney disease
- Serum glycosylated hemoglobin (HbA1c) of 9.5% or lower at Screening.
- Systolic blood pressure of ≤ 140 mm Hg and diastolic blood pressure of ≤ 90 mm Hg at Screening.
- All participants should be strongly considered for treatment with sodium-glucose cotransporter 2 inhibitor (SGLT2i).
- On a clinically relevant, maximally tolerated dose of an angiotensin converting-enzyme inhibitor (ACEI) OR an angiotensin receptor blocker (ARB), unless not tolerated or contraindicated.
- Participant agrees and is able to refrain from using therapies that may increase bleeding risk for the specified pre-procedure and post-procedure durations.
- Participant is willing and able to cooperate with all aspects of the protocol and provide signed informed consent.
You may not qualify if:
- The participant has a history of type 1 diabetes mellitus.
- The participant has a history of renal transplantation or other organ transplantation
- The participant has any other known underlying cause of kidney disease
- History of acute kidney injury or major surgery within 3 months prior to the Screening Visit.
- Myocardial infarction, unstable angina, revascularization procedure or cerebrovascular accident within 12 weeks before randomization, or a revascularization procedure is planned during the trial.
- Current or history of heart failure of New York Heart Association (NYHA) Class IV cardiac disease.
- Documented clinically significant liver disease, including acute or chronic hepatitis B or hepatitis C.
- Known infection with HIV, active syphilis, or other unresolved active genitourinary infection, or active tuberculosis requiring treatment at Screening.
- Immunocompromised condition or condition requiring chronic immunosuppressive agents, including individuals treated for chronic glomerulonephritis, within 3 months of signing ICF.
- Has had a recent bleeding event or a known bleeding disorder(s) or increased risk of either thromboembolism or bleeding.
- Kidney imaging reveals contraindications for undergoing biopsy or rilparencel injection
- Maintained on any anticoagulant agents
- History of anaphylactic or severe systemic reaction(s) to blood transfusions, Dextran 40, or bovine products, or contraindication(s) to above products due to medical reasons or participant preference.
- History of severe systemic reaction(s) or any contraindication to local anesthetics or sedatives.
- Use of an investigational product or device within 12 weeks prior to Randomization or previous treatment with rilparencel.
