About this study
Interstitial lung disease (ILD) is a common pulmonary manifestation of idiopathic inflammatory myopathy (IIM). The overall 5-year mortality is 50%. The prognosis is poor and the treatment is challenging.At present, according to the consensus of IIM-ILD experts, glucocorticoids as first-line treatment are often used in high doses and have a variety of adverse reactions. Previous studies have shown that cyclophosphamide (CYC) is effective for IIM-ILD and tends to be used in rapidly progressive interstitial lung disease（RP-ILD）or refractory ILD. However, CYC is an alkylating agent with many toxic and side effects. It is prone to gonadal inhibition, infection, tumor, hemorrhagic cystitis and other risks. At present, Mycophenolate mofetil (MMF) has been widly used in the treatment of IIM, systemic lupus erythematosus (SLE), ANCA associated vasculitis (AAV). The observational research on MMF in the treatment of IIM-ILD shows that it can delay the progress of pulmonary fibrosis and can be used as the first-line treatment of IIM-ILD. Moreover, immune tolerance caused by defects in the number and/or quality of regulatory T cells (Treg) is considered to be a key source of autoimmune diseases. However, it is unclear whether MMF can improve the immune status of IIM-ILD by increasing Treg cells. The aim of this study was to evaluate the effect of MMF for IIM-ILD and its effcts on Treg through a prospective open single arm study, and provide a theoretical basis for the individualized treatment of IIM-ILD, which has important clinical significance.
Read the detailed description
Interstitial lung disease (ILD) is a common pulmonary manifestation of idiopathic inflammatory myopathy (IIM), with an incidence ranging from 23.1 to 65%. The treatment of IIM patients with ILD is challenging, and the overall 5-year mortality is 50%. The disease process of ILD from stable or slow to rapid. Increased mortality and poor prognosis were observed, which needs active treatment. At present, according to the consensus of IIM-ILD experts, glucocorticoids as first-line treatment are often used in high doses, but have a variety of adverse reactions. Previous studies have shown that cyclophosphamide (CYC) is effective for IIM-ILD and tends to be used in rapidly progressive interstitial lung disease（RP-ILD）or refractory ILD. However, CYC is an alkylating agent with many toxic and side effects. It is prone to gonadal inhibition, infection, tumor, hemorrhagic cystitis and other risks. Mycophenolate mofetil (MMF) has been widly used in the treatment of IIM, systemic lupus erythematosus (SLE), ANCA associated vasculitis (AAV). The observational research on MMF in the treatment of IIM-ILD shows that it can delay the progress of pulmonary fibrosis and can be used as the first-line treatment of IIM-ILD. Moreover, immune tolerance caused by defects in the number and / or quality of regulatory T cells (Treg) is considered to be a key source of autoimmune diseases. In transplant patients, studies have found that the combination of MMF and tacrolimus can increase the number of Treg cells in peripheral blood, suggesting that MMF has a certain regulatory effect on Treg cells. Therefore, it is unclear whether MMF can improve the immune status of IIM-ILD by increasing Treg cells, so as to improve the prognosis of the disease. However, it is unclear whether MMF can improve the immune status of IIM-ILD by increasing Treg cells. The aim of this study was to evaluate the effect of MMF for IIM-ILD and its effcts on Treg through a prospective open single arm study, and provide a theoretical basis for the individualized treatment of IIM-ILD.This was a single-arm open-label pilot observational study. Patients were received prednisone (0.5mg-1.0mg/kg/d ) combined with MMF(1.5g-2.0g/d) for 12 months, 4 weeks later, reduced 5mg every two weeks to 10mg/d orally for 3 months, gradually reduced to 7.5mg/ day until 12 months.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Mycophenolate Mofetil in people with Idiopathic Inflammatory Myopathy and Interstitial Lung Disease, run by First Affiliated Hospital Xi'an Jiaotong University 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 4 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 22 Nov 2021. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Lan He (086-13809156236, Xajdhl87@mail.xjtu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
FVC % predicted (time frame: 12 months). 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 NCT05129410, which also lists 4 linked publications.
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 22 Nov 2021.
