What is being measured

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

  1. DLT rate

    the incidence of dose-limiting toxicity

    Measured: 28 days

  2. Occurrence of AEs and SAEs

    frequency and severity of AEs and SAEs

    Measured: 3 months

Secondary outcomes (16)
  1. Relma-cel cell numbers and transgene copy numbers and duration in blood

    Normally Relma-cel number and transgene copy number will gradually decrease to non-measurable as time goes on.

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  2. the changes of CD19+ cells and other B cell subsets

    Theoretically the number of CD19+ cells and other B cell subsets will significantly decreased following Relma-cel administration and gradually increase to normal level as the effect of Relma-cel disappear

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  3. the change from baseline in Composite Response Index in Systemic Sclerosis (CRISS)

    Criss is an indicator to evaluate the efficacy of systemic sclerosis therapies. A score greater than or equal to 0.6 means Improvement. A score less than 0.6 means No Improvement.

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  4. the change from baseline in Sclerodema Clinical Trial Consortium-Damage Index (SCTC-DI)

    SCTC-DI is a 23-item questionnaire to evaluate the organ damage in patients with systemic sclerosis. The range is between 0-55. The higher the score is, the worse the damage is.

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  5. the change from baseline in modified Rodnan Skin Score (mRSS)

    mRSS is an instrument to evaluate cutaneous involvement in patients with systemic sclerosis. The total score ranges from 0 to 51. The higher the score is, the more the cutaneous involvement is.

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  6. the change from baseline in pulmonary function (forced vital capacity (FVC) and diffusing capacity of the lungs for carbon monoxide (DLCO))

    The two items are used to evaluate pulmonary function. Normally both indicators should be greater than 80%.

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  7. the change from baseline in cardiac function (left ventricular ejection fraction, LVEF)

    LVEF is an indicator of the heart's ability to eject blood out. The normal range is 50-55%

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  8. the change from baseline in high resolution computed tomography (HRCT)

    HRCT is a radiology test of the lungs. In this trial, HRCT will be used to evaluate the lesion size of the lungs, e.g., a lesion could be 10% of the lungs. The greater the percentage is, the worse the lesion is.

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  9. the change from baseline in disease activity score -28 (DAS-28) if any joint involvement

    DAS-28 is a questionnaire to evaluate disease activity in patients with rheumatoid arthritis. 28 joints will be evaluated. Less than 2.6 means the disease is in remission. 2.6-3.2 means a low disease activity. More than 3.2 means active disease needing change in medication. More than 5.1 means very active disease that requires careful monitoring and adjustment to medication

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  10. the change from baseline in the levels of inflammation biomarkers including C-reactive protein (CRP), erythropoietin sedimentation rate (ESR) and ferritin

    CRP, ESR and ferritin are inflammation biomarkers. The normal ranges are different in different labs. Higher values than the upper limit of normal range mean the presence of inflammation.

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  11. systemic sclerosis specific antibodies, e.g., anti-scl-70 antibodies, anti-RNA polymerase III antibodies, anti-centrosome antibodies, antinuclear antibody (ANA)

    Normally all the antibodies are negative in human body. A positive result means abnormalities of immune system.

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  12. the change from baseline in skin biopsy pathology, e.g., the number of lymphocytes, the thickness of epiderm

    In the presence of systemic sclerosis, the increased number of T and B lymphocytes, the thinning of epiderm and the decreased number of sweat gland are expected.

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

  13. the change from baseline in nailfold capillaroscopy examination, e.g., the capillary density, the diameter of capillaries

    nailfold capillaroscopy is a device to observe the capillaries in the nailfold areas. With system sclerosis, the capillary density will diminish and expanded capillary loop may occur

    Measured: 12 months

  14. the change from baseline in skin stiffness (measuring the thickness of epiderm and dermis) by skin ultrasound

    the thickness of epiderm and dermis will be thinner in the presence of systemic sclerosis.

    Measured: 12 months

  15. the change from baseline in health assessment questionnaire -damage index (HAQ-DI)

    HAQ-DI, assesses a patient's level of functional ability and includes questions of fine movements of the upper extremity, locomotor activities of the lower extremity, and activities that involve both upper and lower extremities. There are 20 questions in eight categories of functioning which represent a comprehensive set of functional activities - dressing, rising, eating, walking, hygiene, reach, grip, and usual activities. The stem of each item asks over the past week "Are you able to …" perform a particular task. The patient's responses are made on a scale from zero (no disability) to three (completely disabled). The total score will be 0-3. The higher the score is, the worse the body function is.

    Measured: 12 months

  16. the change from baseline in IgG, IgM, IgE, IgA

    with Relma-cel administration, IgG, IgM, IgE, IgA will significantly decrease, then graduallly increase as the effect of Relma-cel disappears

    Measured: baseline prior to Relma-cel administration, then through study completion, an average of 2 years after Relma-cel administration

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Relma-cel in people with Systemic Sclerosis, run by Liangjing Lu 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 18 inclusion and 16 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 15 Aug 2024. 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 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 Liangjing Lu (86-13661472001, Lu_liangjing@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

DLT rate (time frame: 28 days). 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 15 Aug 2024.
