SCD TECHNOLOGY PLATFORM
• Pulmonary infiltrates • Lung injury • Acute respiratory distress syndrome • Cardiovascular shock • Disseminated intravascular coagulant • Acute kidney injury End - Organ Damage Innate Immune Response Dysregulated immune response (hyperinflammation) H yperinflammatory response can lead to multi - organ damage and death Infection / Injury Activated monocytes Activated neutrophils Other inflammatory mediators Cytokines Patient Outcome: Permanent Organ Damage or Death 10
Neutralization of activated effector cells helps restore homeostasis Cyt okine storm Insult or injury Immune response Increased cytokine production from effector cells and the recruitment of additional leukocytes SCD targets the SOURCE of cytokine production SCD targets upstream source of effector cells and neutralizes effector cells that release cytokines Other drugs and therapies that focus on individual downstream inflammatory targets such as IL - 6, TNF - ⍺ etc. fail to address the high redundance in the immune system 11 Neutrophil & Monocyte effector cells
Mechanism of action of QUELimmune • S electivity of Binding : Neutrophils (70 - 80%), Monocytes (15 - 25%), Lymphocytes (0 - 2%) • Most Activated Neutrophils (CD11b density) and Pro - Inflammatory Monocytes (CD14+) bind to the membranes due to low iCa environment • For Neutrophils : Low iCa environment promotes apoptosis , release from membranes, return to circulation, and clearance by phagocytosis and digestion by bone marrow, liver, and spleen macrophages • For Monocytes : Shift from the most pro - inflammatory circulating phenotype (classical, intermediate) to reparative phenotype (non - classical) This continuous cell processing of circulating neutrophils and monocytes immunomodulates the hyperinflammatory state without immunosuppression and promotes tissue repair and organ recovery 12
