Diffuse Cutaneous Systemic Sclerosis (dcSSc) Understanding and Treatment Algorithm

Diffuse Cutaneous Systemic Sclerosis (dcSSc) Overview 

dcSSc is a severe form of systemic sclerosis, an autoimmune connective tissue disorder marked by widespread skin thickening and significant risk of internal organ involvement. The disease is driven by immune system activation, vascular injury, and excessive collagen deposition, leading to fibrosis of the skin and organs. Skin changes progress rapidly, affecting the face, trunk, and extremities, often preceded by Raynaud’s phenomenon. Internal complications may include interstitial lung disease, pulmonary arterial hypertension, scleroderma renal crisis, cardiac dysfunction, and gastrointestinal motility disorders.

Diffuse Cutaneous Systemic Sclerosis (dcSSc) Diagnosis

Diagnosing systemic sclerosis can be challenging because its symptoms resemble many other conditions. It becomes easier when key signs like Raynaud’s phenomenon or sudden skin swelling/thickening are present. There is no single test diagnosis relies on a detailed medical history, physical examination, and specialized tests. A rheumatologist will check for skin tightening or swelling and may order a skin biopsy, blood tests (including ANA for autoantibodies), and organ assessments. Additional investigations can include lung function tests, CT chest scans, ECGs, echocardiograms, X-rays, and gastrointestinal motility studies to detect internal organ involvement. Diagnosis is always made by considering all findings together, not just a single test. 

Further details related to country-based variations in diagnosis are provided in the report.

Diffuse Cutaneous Systemic Sclerosis (dcSSc) Treatment

Systemic sclerosis is a chronic autoimmune disease with a poor prognosis, and treatment mainly targets organ-related complications. Patients require long-term follow-up with multiple specialists. Immunosuppressants like methotrexate, mycophenolate mofetil, and azathioprine are commonly used, while glucocorticoids are used cautiously. Vasoactive therapies include endothelin receptor antagonists (bosentan, ambrisentan, macitentan), PDE5 inhibitor (sildenafil), prostacyclin analog (iloprost), and calcium channel blockers. For systemic sclerosis-associated interstitial lung disease (SSc-ILD), approved treatments include nintedanib (OFEV), tocilizumab (ACTEMRA), and rituximab, with rituximab being the only one showing significant skin improvement (mRSS). Despite the lack of curative therapies and high healthcare costs, ongoing research has improved patient care.

Diffuse Cutaneous Systemic Sclerosis (dcSSc) Epidemiology

As the market is derived using a patient-based model, the dcSSc epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by total diagnosed prevalent cases of systemic sclerosis, systemic sclerosis by disease subset, age-specific cases of systemic sclerosis, systemic sclerosis with organ involvement, systemic sclerosis severity by organ damage, systemic sclerosis severity by skin thickness, in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain), and the United Kingdom, and Japan from 2020 to 2034. 

• The total number of diagnosed prevalent cases of dcSSc in the 7MM were about ~ 64,250 in 2024.
• Among EU4 and the UK, Germany had the highest number of diagnosed prevalent cases of dcSSc, while the UK had the lowest number of diagnosed prevalent cases.
• Patients with dcSSc tend to have a more aggressive clinical course and eventually develop visceral complications (usually within the first 3 to 5 years), which, if severe, can lead to death.

Marketed Drugs

OFEV (nintedanib): Boehringer Ingelheim

Nintedanib is in a class of medications called kinase inhibitors and works by blocking the action of enzymes involved in causing fibrosis. It is used to treat idiopathic pulmonary fibrosis (IPF) and certain types of chronic fibrosing interstitial lung diseases (ILD). In addition, it is used to slow the rate of decline in lung function in people with SSc-ILD, a disease in which there is scarring of the lungs that is often fatal.

In September 2019, the US FDA approved OFEV capsules to slow the rate of decline in pulmonary function in adults with SSc-ILD.

ACTEMRA (tocilizumab): Roche

ACTEMRA is an anti-IL-6 receptor biologic and is available in both intravenous (IV) and subcutaneous (SC) formulations. The drug is part of a co-development agreement with Chugai Pharmaceutical and has been approved in Japan since April 2005. It is approved for the treatment of various conditions such as Castleman’s disease, rheumatoid arthritis, systemic juvenile idiopathic arthritis (SJIA), polyarticular juvenile idiopathic arthritis, giant cell arteritis, CAR T cell-induced cytokine release syndrome, active polyarticular juvenile idiopathic arthritis, Still's disease, SSc-ILD, and for COVID-19.

In March 2021, the US FDA approved ACTEMRA subcutaneous injection for slowing the rate of decline in pulmonary function in adult patients with SSc-ILD. The FDA approval was based on data from the focuSSced trial. Supportive information was also used from the faSScinate trial.

Emerging Drugs

Dersimelagon (MT-7117): Mitsubishi Tanabe Pharma

Dersimelagon is a synthetic, orally administered, non-peptide small molecule being developed for multiple indications that acts as a selective agonist of MC1R. It reduces inflammation, vascular dysfunction, and fibrosis through its pleiotropic effects on inflammatory cells, endothelial cells, and fibroblasts and is a potential therapeutic agent for the treatment of systemic sclerosis.

In April 2020, Mitsubishi Tanabe Pharma was granted Fast Track Designation for MT-7117 for the treatment of diffuse cutaneous systemic sclerosis.

Ianalumab: Novartis

Ianalumab developed by Novartis, is a novel monoclonal antibody targeting the B-cell activating factor receptor (BAFF-R), designed to deplete B cells through antibody-dependent cellular cytotoxicity (ADCC) and inhibition of B-cell survival signals. Given the central role of B cells in the pathogenesis of dcSSc—including autoantibody production and profibrotic signaling—Ianalumab offers a targeted immunomodulatory approach.

Note: Detailed emerging therapies assessment will be provided in the final report.

Drug Class Insights

In dcSSc, investigational therapies target different pathogenic mechanisms through distinct drug classes. MC1R agonists act on the melanocortin 1 receptor to regulate inflammation, vascular dysfunction, and fibrosis. BAFF inhibitors block B-cell activating factor, reducing abnormal B-cell survival and autoantibody production. TxA2/PGH2 antagonists inhibit thromboxane and prostaglandin signaling to decrease vasoconstriction, platelet aggregation, and fibrosis. IL-23 inhibitors modulate the IL-23/Th17 axis to suppress pro-inflammatory responses linked to disease progression. CD19-directed therapies deplete pathogenic B-cell populations, aiming to reset immune balance and limit autoimmune activity. These novel classes aim to move beyond traditional immunosuppressants by addressing key drivers of dcSSc pathogenesis.

Diffuse Cutaneous Systemic Sclerosis (dcSSc) Market Outlook

The dcSSc treatment landscape is transitioning from traditional symptom management to more target antifibrotic and immunomodulatory approaches, addressing a high unmet need. Approved options include OFEV (nintedanib, Boehringer Ingelheim), the first antifibrotic to slow lung decline in SSc-ILD, ACTEMRA (tocilizumab, Roche), which modulates IL-6–driven inflammation and lung outcomes, and RITUXAN (rituximab, Zenyaku Kogyo/Chugai), a B-cell–depleting therapy used increasingly in practice. The pipeline is diverse, with Mitsubishi Tanabe Pharma’s MT-7117 (melanocortin agonist), Cumberland’s ifetroban (thromboxane receptor antagonist), Johnson & Johnson’s guselkumab (IL-23 inhibitor), and Kyverna’s KYV-101 (engineered T-cell therapy) among leading candidates. The market is expected to shift toward earlier targeted use, combination regimens, and precision-based care, though access and long-term durability remain challenges.
