The paper explores how selectively blocking sFasL with our innovative monoclonal antibody PC111 could potentially transform the treatment landscape for diseases like severe drug reactions (DRESS/DIHS), autoimmune disorders (SLE, RA, Sjogren’s syndrome), and even acute respiratory distress syndrome (ARDS).

This effect adds up to what the PinCell team has shown in pemphigus vulgaris (PV) and Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), where preclinical data demonstrates how it effectively blocks elevated sFasL, preventing blister formation in PV models and reducing apoptosis in SJS/TEN ones, with potential for rapid, non-immunosuppressive intervention.​

In the above conditions:

sFasL drives pathogenesis by promoting inflammation, apoptosis in barrier cells (e.g., keratinocytes, epithelial cells) and tissue damage, without interfering with immune surveillance when it is selectively targeted.​

Elevated sFasL levels correlate with disease severity, potentially positioning it as both a biomarker and druggable target.​
