Trial Summary

What is the purpose of this trial?

This study investigates the efficacy and safety of belimumab compared to placebo, in addition to standard therapy, for the treatment of participants with systemic sclerosis associated interstitial lung disease (SSc-ILD). The study will evaluate the effect of belimumab treatment on lung function as well as on extra-pulmonary disease manifestations, including skin thickening and general symptoms, such as fatigue, that impact quality of life (QoL).

Will I have to stop taking my current medications?

The trial requires stopping certain medications before participating. You must stop taking biologic agents, rituximab, non-biologic systemic immunosuppressive medications (except mycophenolate, methotrexate, or azathioprine), cyclophosphamide, anti-fibrotic agents, cytotoxic drugs, and corticosteroids for specific periods before starting the trial.

What data supports the effectiveness of the drug Belimumab for Systemic Sclerosis Interstitial Lung Disease?

Belimumab has been shown to be effective in reducing disease activity in patients with systemic lupus erythematosus (SLE), a condition where the immune system attacks the body's own tissues, similar to systemic sclerosis. This suggests it might help in other autoimmune conditions like systemic sclerosis, although direct evidence for interstitial lung disease is not available. ^{1 2 3 4 5}

Is belimumab safe for humans?

Belimumab, also known as Benlysta, has been studied for safety in conditions like systemic lupus erythematosus (SLE) and primary Sjögren's syndrome. Long-term studies show it is generally safe when used with standard therapy, although specific side effects can occur, and it is important to discuss these with a healthcare provider. ^{1 4 6 7 8}

How is the drug Belimumab unique for treating systemic sclerosis interstitial lung disease?

Belimumab is unique because it is a biologic drug that targets specific parts of the immune system, which is different from traditional treatments like cyclophosphamide that broadly suppress the immune system. This targeted approach may offer a novel way to manage systemic sclerosis interstitial lung disease by potentially reducing inflammation with fewer side effects. ^{9 10 11 12 13}

I have a suitable skin area for SC injection in my abdomen or thigh.

Exclusion Criteria

I haven't taken any strong chemotherapy drugs like chlorambucil in the last 6 months.

I have been diagnosed with an autoimmune disease, but not dcSSc.

My lung scans show more damage from emphysema than from ILD.

Findings from Research

Benlysta (belimumab) is the first new drug approved for systemic lupus erythematosus (SLE) in 50 years, providing a new treatment option for patients with this complex disease.

Clinical trials suggest that Benlysta is effective in reducing SLE activity and flares in patients who are antinuclear antibody-positive, potentially allowing for lower doses of background medications.

Belimumab and the clinical data. Shum, K., Askanase, A.[2021]

Belimumab (Benlysta®) is an effective treatment for adults with active, autoantibody-positive systemic lupus erythematosus (SLE), particularly for those who have high disease activity despite standard therapy.

In multinational trials, patients receiving belimumab showed significantly higher rates of achieving an SLE Responder Index response at 52 weeks compared to those receiving a placebo.

Belimumab: a guide to its use in systemic lupus erythematosus. Scott, LJ., Burness, CB., McCormack, PL.[2016]

In a study involving 364 patients with systemic lupus erythematosus (SLE), long-term treatment with belimumab combined with standard therapy demonstrated a stable or declining incidence of adverse events over 4 years, indicating a favorable safety profile.

The most common side effects were mild, such as arthralgia and upper respiratory infections, and serious infusion reactions were rare, suggesting that belimumab can be safely administered for extended periods in SLE patients.

In Japan, a significant number of patients with systemic sclerosis (SSc) and SSc-associated interstitial lung disease (SSc-ILD) have been treated with biologics, with 3.5% of SSc patients and 5.0% of SSc-ILD patients receiving these therapies, primarily anti-IL-6 drugs like tocilizumab.

The study found that many patients continued biologic treatment for over a year, indicating a sustained use of these therapies, particularly after prior treatment with immunosuppressive drugs such as methotrexate and tacrolimus.

In a study of 18 patients with systemic sclerosis (SSc), treatment with cyclophosphamide and corticosteroids for one year led to significant improvements in lung function, with 14 out of 18 patients showing increased vital capacity (VC) from 74% to 80% of predicted levels.

The treatment was particularly effective in patients with elevated inflammatory markers, where 11 out of 12 showed improved VC, suggesting that cyclophosphamide may specifically benefit those with active inflammation in pulmonary fibrosis associated with SSc.

Recent clinical trials have confirmed that immunomodulatory treatments are effective in managing interstitial lung disease (ILD) associated with systemic sclerosis (SSc), which can lead to improved clinical outcomes for patients.

There is a need for better methods to identify patient cohorts for clinical trials and for the discovery of biomarkers that could enable more personalized prevention and management strategies for SSc-ILD.

Recent randomized trials indicate that evidence-based algorithms can effectively identify systemic sclerosis patients at risk for lung disease, enabling better monitoring and management.

By recognizing different disease subsets, physicians can tailor treatment strategies that consider individual patient physiology and the effects of specific therapies, improving overall disease management.

In a study of 576 patients with interstitial lung disease (ILD) related to systemic sclerosis, nintedanib significantly reduced the annual decline in forced vital capacity (FVC) compared to placebo, indicating its efficacy in slowing lung function deterioration.

While nintedanib showed benefits in lung function, it did not demonstrate significant improvements in other systemic sclerosis symptoms, and gastrointestinal side effects, particularly diarrhea, were more common in the nintedanib group.
