About this study

Official title: Clinical Study of Human Umbilical Cord Mesenchymal Stem Cells in the Treatment of Refractory Diabetic Peripheral Neuropathy

Diabetic Peripheral Neuropathy (DPN) is one of the most common chronic complications in type 2 diabetes, conventional drug therapy can only target a single pathogenesis but not treat Diabetic Peripheral Neuropathy (DPN) fundamentally. As a novel technique, stem cell transplantation provides a new option for patients with DPN. In 2012, Wuhan Central Hospital, took the lead in carrying out clinical research on the treatment of DPN with autologous bone marrow stem cells in China, and patients were significantly relieved. Based on this research, our clinical trial is to evaluate the safety and efficacy of HUC-MSCs in the treatment of refractory diabetic peripheral neuropathy (DPN) by formulating standard operating procedures (SOP) and quality standards (QS) to explore the possible mechanism of HUC-MSCs in the treatment of DPN.

Read the detailed description

As Diabetes is becoming a health problem of global concern rapidly, DPN, one of the common chronic complications in Diabetes is also getting more and more attention. The result of a survey of 5 regions in Southeast Asia showed that 39-72% of patients with DPN had severe or very severe impact on their quality of life. For the treatment of DPN, conventional drug therapy can almost only target a single pathogenesis and cannot treat it fundamentally. Therefore, new safe and effective treatment options for DPN are particularly important.

Both here and abroad, large number of experimental studies have shown that Bone Marrow or Umbilical Cord Mesenchymal Stem Cells have a significant therapeutic effect on diabetic peripheral neuropathy. In 2012, the Department of Endocrinology of Wuhan Central Hospital took the lead in conducting a clinical study of Autologous Bone Marrow Stem Cells in the treatment of DPN in China. The results of the study showed that the nerve conduction velocity of the lower extremities in most patients was improved within 3 months after treatment compared with before treatment. No serious adverse events occurred during the period. Based on this research of our own. The clinical trial is to evaluate the safety and efficacy of HUC-MSCs in the treatment of refractory diabetic peripheral neuropathy (DPN) by formulating standard operating procedures (SOP) and quality standards (QS) to explore the possible mechanism of HUC-MSCs in the treatment of DPN.

The investigators will do a Single center, randomization, open trial, controlled clinical trials design to assess treatment with the MSCs compared with the control group. 42 patients with DPN will be recruited in China. 21 patients receive i. m. HUC-MSCs both lower extremities (5 × 10^6 cells/mL, 1 mL per injection, each injection point is 2 cm apart ,1.0-1.5 cm deep, total amount of injection is estimated based on the surface area of the patient's lower limbs). 21 patients in the control group received i.v. Lipoic Acid Injection (600 mg/d for 15 consecutive days). Both efficacy and Adverse Event (AE) during the 96 weeks follow up.

What is being measured

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

  1. Change of TCSS scale

    1. Excellent: TCSS score decreased by >30% compared with the baseline value after treatment;
    2. Effective: TCSS score decreased by 30%-15% compared with the baseline value after treatment;
    3. Ineffective: Those who did not achieve the standards above after treatment.

    Measured: Change from Baseline TCSS scale at week 24

  2. Change of nerve conduction velocities in the lower extremity

    1. Excellent: after treatment, the lower extremity nerve conduction velocity and amplitude increased by more than 15% compared with the baseline value;
    2. Effective: after treatment, the lower extremity nerve conduction velocity and amplitude increased by 15%-5% compared with the baseline value;
    3. Ineffective: Those who did not achieve the standards above after treatment.

    Measured: Change from Baseline nerve conduction velocities in the lower extremity at week 12

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing HUC-MSCs and Lipoic Acid in people with Diabetic Peripheral Neuropathy Type 2, run by Wuhan Central Hospital 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 6 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 19 Aug 2022. 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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

Contact WEI WEI (+8615927268614, vivi880614@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of TCSS scale (time frame: Change from Baseline TCSS scale at week 24). 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 19 Aug 2022.
