About this study

Official title: Safety, Tolerability, and Preliminary Efficacy of Human Umbilical Cord Mesenchymal Stem Cell Injection Via Intravenous Infusion in Type 2 Diabetic Nephropathy: A Phase I/IIa Clinical Trial

Diabetic nephropathy (DN) is a chronic kidney disease caused by diabetes. It is one of the most common and most serious microvascular complications of diabetes. Current treatment options for DN are limited. Mesenchymal stem cells (MSCs) are considered one of the promising treatments for DN. This study aims to evaluate the safety, tolerability, and preliminary efficacy of human umbilical cord mesenchymal stem cell injection in patients with type 2 DN.

Read the detailed description

This is a Phase I/IIa clinical trial evaluating the safety, tolerability, and preliminary efficacy of human umbilical cord mesenchymal stem cell injection in patients with type 2 DN. Phase I is a single-center, prospective, open-label, self-controlled study to evaluate the safety and tolerability of MSCs and determine the recommended Phase II dose (RP2D). Phase IIa is a randomized, open-label, standard treatment-controlled study to preliminarily evaluate efficacy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Human umbilical cord mesenchymal stem cell injectionBiological

    Participants will receive intravenous infusions of allogeneic human umbilical cord MSCs in addition to standard treatment. Phase I will evaluate three dose levels (0.5×10^6/kg, 1.0×10^6/kg and 2.0×10^6/kg). Phase IIa will use dose level 1.0×10^6/kg, subject to adjustment based on Phase I results. Each 6-week treatment cycle will include three infusions administered at 2-week intervals, for a total of three treatment cycles.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase I: Incidence and severity of adverse events (AEs) and serious adverse events (SAEs), and clinically significant abnormalities in vital signs, electrocardiogram (ECG), and laboratory tests

    AEs and SAEs will be graded according to the NCI-CTCAE version 5.0. Changes in vital signs, ECG, and routine laboratory tests will be monitored throughout the study. The recommended Phase II dose (RP2D) will be determined from Phase I results.

    Measured: From enrollment to 6 months after the end of treatment

  2. Phase IIa: Proportion of participants achieving marked response or moderate response to human umbilical cord mesenchymal stem cell injection for type 2 DN

    Marked response is defined as significant improvement in clinical symptoms together with complete remission of proteinuria [urinary albumin-to-creatinine ratio (UACR) <30 mg/g], or significant improvement in estimated glomerular filtration rate (eGFR) (serum creatinine reduced by ≥20%). Moderate response is defined as partial alleviation of clinical symptoms and partial remission of proteinuria without complete resolution; either the UACR or 24-hour urinary protein level decreases by ≥50%, or eGFR improves (serum creatinine reduced by ≥10%). No response is defined as no improvement in clinical symptoms and no remission of proteinuria. The reduction of either UACR or 24-hour urinary protein level is less than 50%, and there is no improvement in eGFR (serum creatinine reduced by <10%).

    Measured: From enrollment to 6 months after the end of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Human umbilical cord mesenchymal stem cell injection in people with Diabetic Nephropathy Type 2, run by The First People's Hospital of Changzhou at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 31 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 18 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Fei Hua (+86-051968870000, Huafei1970@suda.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase I: Incidence and severity of adverse events (AEs) and serious adverse events (SAEs), and clinically significant abnormalities in vital signs, electrocardiogram (ECG), and laboratory tests (time frame: From enrollment to 6 months after the end of treatment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2026.
