About this study

Official title: Long-term Follow-up for Safety Evaluation of Subjects Who Participated in the Phase 1 Clinical Trial of CS20AT04(CS20AT04-LN101) in Lupus Nephritis

This observation study is planned to evaluate the safety and efficacy of the subjects who received CS20AT04 in the phase 1 clinical trial.

If the subjects who participated in the phase 1 clinical trial voluntarily agree to participate in this observation study, visit 1 and visit 2 will be conducted every 3 months according to the clinical trial protocol until 6 months after administration of CS20AT04 in the phase 1 clinical trial. And Visit 3 after 6 months, Visit 4~Visit 7 will be conducted every 12 months. During each visit, subjects are assessed for the efficacy and occurrence of adverse events.

Read the detailed description

Lupus is a representative autoimmune disease that affects the whole body. It is occurred by generation of autoantibody and immune complex due to abnormal activation of the immune cells on the basis of abnormal immune responses.

Although about 50% of lupus patients have lupus nephritis, there is no therapeutic product targeting for the lupus nephritis so far.

The investigator has performed the pre-clinical and clinical studies using allogenic bone marrow derived mesenchymal stem cells in SLE.

CS20AT04 has anti-inflammatory effects, controls activity of immune cells and reduces generation of autoantibodies. So, it is expected to have therapeutic effects on lupus nephritis.

Phase 1 clinical trial was conducted as a single center, open-label.

The main component of CS20AT04 is bone marrow-derived mesenchymal stem cells. And the risk of tumor formation is low. Through the repeated administration and long-term observation with mouse model, it was confirmed that there was no oncogenicity. In addition, it was confirmed through the cell residual tracking test of the animal model that the in vivo residual period was shorter than 14 days.

However, since long-term safety has not been evaluated after administering CS20AT04 to humans, the investigator will confirm the safety of stem cells for up to 5 years according to the risk management plan for stem cell products of the Ministry of Food and Drug Safety and already approved phase 1 clinical trial.

Also In the phase 1 clinical trial that only confirmed safety and tolerability for 28 days after administration of CS20AT04, it is difficult to confirm the continuous change of the indicator for evaluating efficacy.

So, it is necessary to check the efficacy in this observation study.

What is being measured

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

  1. Incidence of adverse events

    After the completion of the CS20AT04-LN101 phase 1 trail, new adverse events, including tumor are assessed and detailed information is collected at each visit.

    Measured: up to 57 months after enrollment

  2. Incidence of abnormal results of Physical examination

    Physical examination is performed at each visit. If clinically significant abnormal findings are recorded in the CRF and collected as AEs.

    Measured: up to 57 months after enrollment

  3. Percentage of abnormal Vital signs

    Percentage of abnormal Blood pressure (mmHg) and Pulse rate (beat per minute)

    Measured: up to 57 months after enrollment

  4. Percentage of abnormal results of Laboratory tests

    The following laboratory tests are performed at each visit

    • Hematology test: WBC, RBC, Hemoglobin, Hematocrit, Platelet count, WBC Diffcount, ESR
    • Chemistry test : Total protein, Albumin, Total bilirubin, SGOT(AST), SGPT(ALT), rGTP, Sodium, Potassium, BUN, Creatinine, Glucose, Alkaline Phosphatase, Chloride, Total cholesterol, Triglyceride, Uric Acid , CPK, LDH, CRP, Adolase
    • Urine analysis : Protein, Creatinine, Glucose, Urobilinogen, WBC, RBC, Urine Sediment, Creatinine, Urine albumin creatinine ratio, Urine protein creatinine ratio

    Measured: up to 57 months after enrollment

Secondary outcomes (4)

  1. SLEDAI-2K (Systemic Lupus Erythematosus Disease Activity Index-2000)

    Evaluate disease activity of 9 organ systems and display it as a score. The score is weighted from 1 to 8 at each system, if descriptor is present at the time of visit or in the proceeding 10 days.

    • Change in SLEDAI>3 points means mild or moderate flare
    • Change in SLEDAI>12 points means severe flare

    Measured: up to 57 months after enrollment

  2. BILAG 2004 (British Isles Lupus Assessment Group 2004)

    The change in disease activity in the last 4 weeks compared to the previous 4 weeks is evaluated as score.

    Measured: up to 57 months after enrollment

  3. SDI (Systemic Lupus International Collaborating Clinics/Americans College of Rheumatology (SLICC/ACR) Damage Index

    Only if the damage due to the disease lasted for at least 6 months is evaluated on a scale 0-47.

    Measured: up to 57 months after enrollment

  4. Disease activity assessed by PGA (Physician Global Assessment)

    Investigator evaluated disease activity in mm using 0 to 100mm visual analogue scale (VAS). High score indicates worsening of the disease.

    Measured: up to 57 months after enrollment

Questions about this trial

What is this clinical trial studying?

An observational study of Lupus Nephritis, run by Corestemchemon, Inc. at 1 site in South Korea.

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 9 inclusion and 30 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: finished, as of the sponsor's last update on 10 Jan 2025. 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 South Korea. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of adverse events (time frame: up to 57 months after enrollment). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04522505.

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 10 Jan 2025.
