ADSCs Therapy in Patients With CTD-ILD

Allogenic Adipose Tissue Derived-MSCs Therapy in Patients With Connective Tissue Diseases-associated Interstitial Lung Disease(CTD-ILD): Phase I/IIa Clinical Trial

About This Trial

Connective tissue disease (CTD), an autoimmune and inflammatory disease, usually accompanied by lung interstitial/alveolar inflammation and fibrosis (so called interstitial lung disease, ILD). The prevalence and mortality rate of CTD-ILD increase in recent several years. Although the use of corticosteroids and strong immunosuppressants can improve ILD in some patients with CTD, progressive lung fibrosis which needs lung transplantation and results in respiratory failure, even with mortality is observed. Currently, stem cell therapy is a breakthrough in the treatment of CTD-ILD, and the effective therapy with stem cells for patients with ILD have been reported.

Who May Be Eligible (Plain English)

Who May Qualify: 1. Adult subjects aged between 20 and 80 years who meet the diagnostic criteria for connective tissue diseases such as dermatomyositis, polymyositis, scleroderma, systemic lupus erythematosus, rheumatoid arthritis, or Sjogren's syndrome. 2. Subjects with refractory or progressive fibrotic interstitial lung disease: Subjects have been treated with steroids and potent immunosuppressants for more than 24 months with continued deterioration of lung function or lung lesions on CT scan (defined as a forced vital capacity (FVC) decline of more than 10% from baseline, an FVC decline of 5-10% with a diffusing capacity for carbon monoxide (DLCO) decline of more than 15% from baseline, or enlargement of lung lesions on CT scan) ; Or subjects with rapidly progressive interstitial lung disease: treated with high-dose steroids (above 0.8 mg/kg/day) and potent immunosuppressants for more than 3 months with continued deterioration of lung function or lung lesions on CT scan (defined as an FVC decline of more than 5% from baseline, a DLCO decline of more than 10% from baseline, or enlargement of lung lesions on CT scan); subjects with rapidly worsening condition: Onset of pulmonary symptoms within one month, gradual worsening of dyspnea and decreased blood oxygen levels, or enlargement of lung lesions. 3. Subjects must have a well-established family support system confirmed by interviews with the principal investigator and social worker. 4. Negative high-sensitivity urine pregnancy test before the trial. 5. Agree to use effective contraceptive measures during the trial (e.g., taking contraceptive pills or using intrauterine devices one month before the trial). Who Should NOT Join This Trial: 1. Subjects who are unwilling to sign the willing to sign a consent form form after detailed explanation by the physician. ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Treatments Being Tested

BIOLOGICAL

ADSC01

The initial 3 subjects will receive low-dose AD-MSC (1x10E6 cells/kg) infusion therapy only once; if no adverse events after 4 weeks, the next 4-7 subjects will receive medium-dose AD-MSC (1x10E6 cells/kg) infusion therapy twice; if no adverse events after 4 weeks of the last infusion, the next 8-10 subjects will receive high-dose AD-MSC (1x10E6 cells/kg) infusion therapy three times.
