About this study
Dermatomyositis is a heterogeneous disease characterized by involvement of the proximal muscles of the extremities. Some patients have treatment failure or intolerance to the above treatment regimens, which is called refractory dermatomyositis. Abatacept has been approved by the FDA for the treatment of three types of rheumatoid immune diseases, and the international consensus of experts recommends abacepil as a second-line regimen for the treatment of refractory dermatomyositis based on the evidence of case reports.
Read the detailed description
Dermatomyositis is a heterogeneous disease characterized by involvement of the proximal muscles of the extremities. Some patients have skin, lung and other systems involved. The clinical manifestations of dermatomyositis are varied and vary from person to person, so the treatment should follow the principle of individualization. At present, glucocorticoid combined with immunosuppressants (including methotrexate, azathioprine, cyclosporine, tacrolimus, mycophoranate, cyclophosphamide, etc.) is the first choice for the treatment of dermatomyositis. Some patients have treatment failure or intolerance to the above treatment regimens, which is called refractory dermatomyositis. There has not been a large-scale study to explore the treatment regimens. Abatacept is a CTLA-4 fusion protein that inhibits T cell activation by competitively binding to CD80/CD86 and blocking the second signal. To date, Abatacept has been approved by the FDA for the treatment of three types of rheumatoid immune diseases (refractory rheumatoid arthritis, juvenile idiopathic arthritis, and active psoriatic arthritis). The international consensus of experts recommends abacepil as a second-line regimen for the treatment of refractory dermatomyositis based on the evidence of case reports. However, to date, there is no relevant report or clinical study registration information of Abatacept in the treatment of dermatomyositis. The purpose of this study was to prospectively observe the efficacy and safety of Abatacept in the treatment of refractory dermatomyositis through a controlled before and after study.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Abatacept in people with Dermatomyositis and Abatacept, run by The First Affiliated Hospital with Nanjing Medical 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 7 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 1 Jul 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?
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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
IMACS score improved (time frame: 12 weeks after treat with Abatacept). 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 1 Jul 2021.
