What is being measured

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

  1. The maximum tolerable dose (MTD) and / or dose range of CT1195E were evaluated

    CT1195E MTD and/or dose range

    Measured: After medication to day 28

  2. severity of dose limiting toxicity (DLT)

    Measured: Within 28 days after infusion

  3. severity of adverse events (AES)

    Measured: Within 180 days after infusion

  4. Incidence of adverse events (AES)

    Measured: Within 180 days after infusion

  5. Incidence of dose limiting toxicity (DLT)

    Measured: Within 28 days after infusion

Secondary outcomes (18)
  1. Changes of systemic sclerosis comprehensive response index score (acr-criss) from baseline

    The score range of the comprehensive response index for systemic sclerosis (acr-criss) is usually 0 to 100, where 0 represents the lowest disease activity and burden, and 100 represents the highest. The higher the score, the higher the disease activity, severity of skin involvement or overall disease burden of systemic sclerosis.

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  2. Changes from baseline in scleroderma clinical trials Association injury index (sctc-di)

    The minimum value of scleroderma clinical trials Association injury index (sctc-di) is 0 and the maximum value is 42. The higher the score, the more serious the organ damage, that is, the worse the result.

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  3. Changes from baseline in modified Rodnan skin scale (MRSS)

    The minimum value of the modified Rodnan skin scale (MRSS) is 0 points, and the maximum value is 57 points. The higher the score, the more severe the degree of skin sclerosis, that is, the worse the result. MRSS quantifies the skin involvement of systemic sclerosis by evaluating the skin hardness of 19 parts of the body. 0 points represent normal skin and 3 points represent severe thickening. The higher the total score, the more extensive and severe skin fibrosis, which is associated with disease activity and poor prognosis.

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  4. Changes in lung function (FVC) from baseline

    The normal value of FVC in healthy adults usually ranges from 3 to 5 liters, and the specific value varies according to age, sex, height, race and other factors. Higher FVC values usually indicate better lung function, because higher FVC means greater lung volume and stronger respiratory muscle strength.

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  5. Changes from baseline in left ventricular ejection fraction (LVEF) by cardiac function tests

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  6. Changes of joint disease activity score (DAS-28) (if joint involvement) from baseline

    The minimum value of joint disease activity score (DAS-28) is 0 and the maximum value is 10. The higher the score, the higher the disease activity, that is, the worse the result, because the score is used to measure the activity of joint inflammation, and the increase of the score reflects the enhanced disease activity.

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  7. Changes of inflammation related indicators (CRP or ESR) from baseline

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  8. SSC specific antibodies (changes in anti-Scl-70 antibody levels from baseline

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  9. Changes of anti RNA polymerase III antibody [rp155, rp11] levels from baseline

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  10. Immune related autoantibodies (antinuclear antibody ANA) levels and changes from baseline

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  11. Proportion of patients without other SSC therapies after medication

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  12. Vascular lesions were assessed by nailfold capillary microscopy after medication

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  13. Skin elasticity was assessed by skin ultrasound after medication

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  14. Changes of chest HRCT in study participants after medication evaluation

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  15. Change from baseline in the post medication Health Assessment Questionnaire Disability Index (HAQ-DI)

    The score range of the Health Assessment Questionnaire Disability Index (HAQ-DI) is usually 0 to 3, where 0 represents no disability or functional integrity, and 3 represents severe disability or inability to complete activities. The higher the score, the worse the patient's functional status, because HAQ-DI quantifies the degree of disability by evaluating the ability of daily activities, for example, the increased score in items such as dressing and walking reflects the increased difficulty.

    Measured: 2 months and other time points after medication (the 1st, 3st, 6th, 9th and 12th months)

  16. The level of CT1195e transgene copy number in blood

    Measured: Within 1 year after CAR-T cell infusion

  17. Changes of B cell functional subsets (initial B cells, memory B cells, plasma cells) after ct1195E infusion

    Measured: Within 1 year after CAR-T cell infusion

  18. Duration of ct1195e transgene copy number in blood

    Measured: Within 1 year after CAR-T cell infusion

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing CAR-T Therapy in people with SSc-Systemic Sclerosis, run by Union Hospital, Tongji Medical College, Huazhong University of Science and Technology 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 19 inclusion and 20 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 21 Jan 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 phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 Qiubai Li (Professor 85726808 Ext.027, qiubaili@hust.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The maximum tolerable dose (MTD) and / or dose range of CT1195E were evaluated (time frame: After medication to day 28). The study lists 5 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 21 Jan 2026.
