About this study

Official title: An Open-Label, Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Allogeneic CAR-T Cell Therapy (OL-108) in the Treatment of Relapsed/Refractory Autoimmune Diseases

This study aims to characterize the safety, tolerability, pharmacokinetics, and preliminary efficacy of OL-108 in relapsed/refractory autoimmune diseases.

Read the detailed description

This is an open-label, single-arm, clinical study to evaluate the efficacy and safety of CAR-T therapy OL-108 in the treatment of Relapsed/ Refractory Autoimmune Disease such as SLE, IIM, SSc and AAV.

Being tested
OL-108
Medical subject headings
Lupus Erythematosus, Systemic, Myositis, Scleroderma, Systemic, Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis

What participants receive

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

  • OL-108Biological

    OL-108 will be given through IV bolus with ascending dose levels to determine the maximum tolerated dose (MTD)

Study groups in NCT06980597
Study groupRoleWhat they receive
OL-108ExperimentalNot described
Receives: Biological: OL-108

What is being measured

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

  1. Dose-limiting toxicity (DLT)

    Adverse events will be assessed based on the CTCAE 5.0

    Measured: After OL-108 administration up to 30 days (Day 1-Day 30)

  2. Treatment emergent adverse event (TEAE) incidence and severity

    Adverse events will be assessed based on the CTCAE 5.0

    Measured: From lymphodepletion through study completion, up to 2 years

Secondary outcomes (7)
  1. Overall Response Rate

    The efficacy outcome variable, Overall Response Rate (ORR), is defined as the ratio between the number of subjects experiencing a response at weeks 12, 24 and 52 and the total number of enrolled subjects.

    A response to treatment will be considered as:

    • SLE: Fulfillment of DORIS remission/LLDAS criteria of SLE.
    • SSc: Fulfillment of mCRISS criteria
    • IIM: 2016 ACR/EULAR Total Improvement Score.
    • AAV: Birmingham vasculitis activity score (BVAS) of 0.

    Measured: Baseline through study completion, up to 2 years

  2. Cmax of OL-108

    The maximum concentration of the CAR-T cells will be measured to assess OL-108 in vivo expansion and persistence.

    Measured: Baseline through study completion, up to 2 years

  3. Tmax of OL-108

    The time of the maximum concentration will be measured to assess OL-108 in vivo expansion and persistence.

    Measured: Baseline through study completion, up to 2 years

  4. AUC 0-28 days of OL-108

    Area under the curve will be measured to assess OL-108 in vivo expansion and persistence.

    Measured: Baseline through study completion, up to 2 years

  5. Serum cytokines

    The levels of cytokines will be measured, such as IL-6 and ferritin.

    Measured: From lymphodepletion till day 90

  6. Level of Immunogenicity

    To assess the presence of antibodies to OL-108 (ADA)

    Measured: Baseline through study completion, up to 2 years

  7. Level of RCR

    To determine whether Replication Competent Retrovirus (RCR) is present in patients that receive OL-108

    Measured: Baseline through study completion, up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing OL-108 in people with Systemic Lupus Erythematosus (SLE) and Idiopathic Inflammatory Myopathy (IIM), run by Beijing GoBroad Hospital at 2 sites 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 13 inclusion and 19 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: looking for participants now, as of the sponsor's last update on 20 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 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.

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 Kai Hu (+86 150 1039 0336, huk@gobroadhealthcare.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose-limiting toxicity (DLT) (time frame: After OL-108 administration up to 30 days (Day 1-Day 30)). 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 20 May 2025.
