Systemic Sclerosis (SSc)

systemic sclerosis (SSc) is a rare, autoimmune connective tissue disease of unknown origin affecting the skin and visceral organs, which leads to excess morbidity and premature mortality. Specialized drug and therapy development services are essential to enhance and expedite Systemic Sclerosis research. Our company is well-equipped to address your drug and therapy development requirements in Systemic Sclerosis therapy.

Introduction to Systemic Sclerosis

Systemic Sclerosis is a multifaceted autoimmune disease marked by skin and internal organ fibrosis, vascular alterations, and immune system dysregulation. The disease is relatively rare, with global incidence rates varying considerably, but generally found to be around 1.4 per 100,000 person-years. It primarily affects women more than men, and its presentation can vary significantly from one individual to another, contributing to the complexity of its management and diagnosis​​.

Pathogenesis of Systemic Sclerosis

Systemic Sclerosis is driven by an abnormal immune response that activates fibroblasts through cytokines and autoantibodies from immune cells like macrophages and B cells, leading to excessive collagen production and subsequent tissue fibrosis. Vascular issues, including endothelial damage and vasculopathy, exacerbate complications such as Raynaud's phenomenon and pulmonary hypertension, highlighting the disease's complexity.

Diagnostics Development of Systemic Sclerosis

  • Autoantibody testing:
    Antinuclear antibodies (ANA), anti-topoisomerase antibodies (anti-Scl-70), and anti-centromere antibodies can help diagnose.
  • Inflammatory markers:
    Individuals commonly have elevated serum inflammatory markers such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR).
  • Biomarker development:
    Research is ongoing to identify biomarkers to diagnose the disease early and predict its progression.

Therapy Development of Systemic Sclerosis

Small Molecule Drugs

Small molecule drugs target molecular pathways to treat Systemic Sclerosis, such as Nintedanib and Pirfenidone for Systemic Sclerosis-related interstitial lung disease (ILD). These drugs inhibit fibrosis and inflammation by targeting tyrosine kinases and TGF-beta respectively​​.

Cell Therapies

Cell therapies, including Mesenchymal Stem Cells (MSCs) and Hematopoietic Stem Cell Transplantation (HSCT), aim to treat Systemic Sclerosis through immune modulation and tissue repair. MSCs reduce fibrosis while HSCT may offer long-term symptom remission.

Monoclonal Antibodies

Monoclonal antibodies like Rituximab and Tocilizumab target specific molecules in the immune system to alleviate Systemic Sclerosis symptoms. They help reduce muscle weakness, skin fibrosis, and disease progression by blocking molecules like CD20 and IL-6.

Gene Therapies

Gene therapies attempt to treat Systemic Sclerosis by modifying or silencing genes linked to the disease progression, such as using antisense oligonucleotides targeting TGF-beta mRNA. These therapies are mostly experimental but show potential for future therapy possibilities.
