Inflammatory myositis (IM) Disease Understanding and Treatment Algorithm

The term myositis refers to a condition where there is inflammation of muscle. In practice, myositis tends to be associated with the idiopathic inflammatory myopathies (IMM): polymyositis (PM), dermatomyositis (DM), juvenile dermatomyositis, overlap myositis, and inclusion body myositis (IBM). In contrast, myopathy refers to any abnormal condition or disease of muscle and, by definition, includes myositis.

Myositis is a rare condition that can affect multiple organs apart from muscles and often leads to severe impairment of the quality of life. According to the American College of Rheumatology, inflammatory myopathies are muscle diseases caused by inflammation. Myopathy is a general term used to describe several conditions affecting the muscles. They are autoimmune diseases where the body's immune system mistakenly attacks its muscles. The most common inflammatory myopathies are dermatomyositis and polymyositis.

Inflammatory myositis (IM) Diagnosis

Diagnosing myopathies involves a laboratory evaluation, imaging studies, multidisciplinary consultations, histologic examination, and potentially genetic studies. To properly diagnose the patient with muscle weakness, testing should include a thorough history and physical examination, routine laboratory tests (complete blood count, complete metabolic panel, muscle enzymes, thyroid-stimulating hormone, and other targeted studies as necessary), autoimmune serologies, imaging studies, neurologic evaluation, EMG, nerve conduction velocities and muscle biopsy. The history and physical examination allow the patient to describe the onset of the disease.

Inflammatory myositis (IM) Treatment

The treatment landscape for inflammatory myositis (including dermatomyositis, polymyositis, and inclusion body myositis) involves a combination of medications and supportive therapies. The specific treatment approach may vary depending on the individual's symptoms, disease severity, and response to previous treatments. Some common treatment options are:

Corticosteroids: High-dose corticosteroids, such as prednisone, are often the first-line treatment for inflammatory myositis. They help reduce inflammation and suppress the immune response. The dosage is typically gradually reduced to find the lowest effective dose.

Immunosuppressants: Immunosuppressant medications may be added if corticosteroids are insufficient or long-term corticosteroid use is not desirable. Examples include methotrexate, azathioprine, mycophenolate mofetil, and cyclosporine. These drugs work by suppressing the immune system and reducing inflammation.

Biologic agents: In some cases, biologic agents may be used for more severe or refractory cases of inflammatory myositis. Rituximab, for example, targets specific immune cells involved in the disease process. Other biologics, such as tocilizumab or abatacept, may also be considered in certain cases.

Intravenous immunoglobulin (IVIG): IVIG is a treatment option for some individuals with dermatomyositis or polymyositis who do not respond to other therapies. It involves infusions of immunoglobulin to modulate the immune system.

It is important to note that the inclusion body myositis (IBM) treatment is particularly challenging, as it is generally less responsive to immunosuppressive therapies. Currently, no specific treatment can stop or reverse the progression of IBM; however, supportive therapies, physical therapy, and management of symptoms can help improve quality of life.

A high unmet need prevails in the current therapies for treating Inflammatory myositis as current treatment approaches for inflammatory myositis typically involve immunosuppressive medications such as corticosteroids and disease-modifying antirheumatic drugs (DMARDs). However, these therapies are not always effective for all patients, and some individuals may experience inadequate response or significant side effects.

To cater to their needs, many molecules are in the pipeline to treat Inflammatory myositis patients across the 7MM. Some major products are anticipated to hit the market during 2023-2032, including Efgartigimod alfa, Ravulizumab, Brepocitinib, PF-06823859, and Hizentra.

Emerging Drugs:

Efgartigimod: Argenx

Efgartigimod, an experimental antibody fragment, is specifically designed to target the neonatal Fc receptor (FcRn) and is considered a pioneering treatment option. It is currently undergoing evaluation for its potential to treat patients who suffer from inflammatory myositis, a severe autoimmune disease. These patients have confirmed levels of pathogenic immunoglobulin G (IgG) autoantibodies, and there is a significant lack of effective medical solutions for their condition.

PF-06823859, an investigational drug developed by Pfizer, is currently in Phase II developmental stages as a potential treatment for moderate-to-severe dermatomyositis and lupus. This drug candidate is categorized as a new biological entity (NBE) and is a humanized immunoglobulin-neutralizing antibody. It is administered via IV and SC injection and works by specifically targeting interferon beta 1 (IFNB1), a key cytokine involved in the pathogenesis of these diseases.

Detailed emerging therapies list will be provided in the final report.

Inflammatory myositis (IM) Market Outlook

The treatment landscape for inflammatory myositis has evolved over the years. Current treatment approaches involve a combination of immunosuppressive medications, such as corticosteroids and disease-modifying anti-rheumatic drugs (DMARDs) i.e. immunosuppressive agents, biologic agents, physical therapy, and supportive measures. However, there is still an unmet need for more effective and targeted therapies with fewer side effects. The development of novel treatments, including biologics and small molecule inhibitors, could significantly impact the market outlook by offering new options for patients.

The effectiveness and safety of intravenous immunoglobulin (IVIg) as the initial treatment for patients diagnosed with idiopathic inflammatory myopathy. First-line IVIg monotherapy demonstrated effectiveness in approximately 50% of patients with idiopathic inflammatory myopathies. In most cases, treatment response was achieved within three weeks of initiating IVIg therapy among those who responded positively. If treatment with corticosteroids, immunosuppressive agents, and IVIG fails to alleviate symptoms, IV cyclophosphamide can be considered as a fourth-line treatment. However, it is associated with potential severe side effects and is typically reserved for patients with severe refractory disease, such as profound muscle weakness, swallowing difficulties, and interstitial lung disease. Treatment plans may vary depending on the individual's specific condition, disease severity, response to treatment, and the expertise of the treating physician.

In light of the above, some developmental initiatives have been taken toward the management of IM. The condition may evolve as some interesting therapies are heading down the pipeline. This would encourage reimbursement scenarios, doctors' adoption, and patient compliance. Some companies have initiated clinical trials investigating new treatment options, including Argenx (Efgartigimod), CSL Behring (Hizentra), Pfizer (PF-06823859), Priovant Therapeutics (Beprocitinib), and Alexion Pharmaceuticals (Ravulizumab) as the potential therapies lined up for forecast in the 7MM in the DelveInsight therapeutics market model.
