What side effects are associated with this type of intervention?

Common treatments for inflammatory myositis include corticosteroids, immunosuppressants, biologics, and JAK inhibitors. Corticosteroids can cause side effects such as weight gain, osteoporosis, hypertension, and increased risk of infections. Immunosuppressants like methotrexate may lead to liver toxicity, bone marrow suppression, and gastrointestinal issues. Biologics, particularly TNF-alpha inhibitors, are associated with increased risk of infections, potential cardiovascular events, and injection site reactions. JAK inhibitors, such as tofacitinib, can cause venous thrombosis, pulmonary embolism, infections, and malignancies. These side effects should be carefully considered when choosing a treatment plan.

What prior FDA approvals exist?

FDA-approved treatments for Inflammatory Myositis include immunosuppressive and immunomodulatory drugs such as methotrexate, azathioprine, and mycophenolate mofetil. These drugs are often used when patients do not respond adequately to corticosteroids. Additionally, biologic agents like rituximab, which targets B-cells, and intravenous immunoglobulin (IVIG) have been used for refractory cases. These treatments aim to reduce inflammation and modulate the immune response, similar to the objectives of the trial studying Daxdilimab.

What other types of research exist?

Promising novel alternatives to Daxdilimab for Inflammatory Myositis patients include: <ol> <li>Secukinumab - an IL-17A inhibitor, which has shown efficacy in conditions like psoriatic arthritis and ankylosing spondylitis.</li> <li></li> </ol> Tofacitinib - a Janus kinase (JAK) inhibitor, effective in psoriatic arthritis and other inflammatory conditions. 3. Ustekinumab - an IL-12/23 inhibitor, which has demonstrated benefits in psoriatic arthritis and other autoimmune diseases. These alternatives target specific inflammatory pathways and have shown promising results in clinical trials for related conditions.

Study Summary

This trial evaluates the effectiveness of a drug (daxdilimab) to reduce symptoms, and its safety and tolerability.

Who is the study for?

This trial is for adults aged 18-75 with a diagnosis of dermatomyositis (DM) or anti-synthetase inflammatory myositis (ASIM), meeting specific criteria like muscle weakness and elevated muscle enzymes. Participants must not have severe infections, other connective tissue diseases that affect assessment, significant organ damage, or be pregnant. They should agree to potentially taper off corticosteroids.Check my eligibility

What is being tested?

The study tests Daxdilimab's effectiveness compared to a placebo in reducing disease activity by week 24. It also looks at its impact on skin symptoms and the possibility of lowering corticosteroid use. Additionally, it will assess how the body processes the drug and any potential immune response to it.See study design

What are the potential side effects?

While not explicitly listed here, common side effects may include reactions at the injection site, increased risk of infection due to immune system suppression, possible liver enzyme changes, fatigue, headache, and gastrointestinal issues.

Other Research

Common treatments for Inflammatory Myositis, such as infliximab, tacrolimus, and tofacitinib, work by modulating the immune system to reduce inflammation. Infliximab is an anti-TNF-alpha therapy that blocks tumor necrosis factor-alpha, a cytokine involved in systemic inflammation. Tacrolimus is a calcineurin inhibitor that suppresses T-cell activation, thereby reducing immune response. Tofacitinib is a Janus kinase (JAK) inhibitor that interferes with the JAK-STAT signaling pathway, which is crucial for the immune response. These mechanisms are important for patients with Inflammatory Myositis because they help to control the overactive immune response that leads to muscle inflammation and damage, thereby improving symptoms and quality of life.
