ISD-Immunotech is developing a first-in-class therapy to treat the most severe Systemic lupus erythematosus (SLE) patients. The therapy works by dampening the action of an intracellular protein called STimulator of INterferon Genes (STING). STING is part of the innate immune system, the body’s first line of defense against pathogen invaders like bacteria and viruses. When activated, STING ramps up production of inflammatory proteins called interferons and cytokines. STING overactivity has recently been linked to severe SLE. SLE is an autoimmune disease that can affect any organ of the body including the skin, joints, heart, kidneys, lungs, nervous system and others. As immune cells attack the body, inflammation, scarring, and permanent damage ensue, leading to worsened function and sometimes even organ failure and death.
Today there is no drug that can significantly alter the disease for severe SLE patients. ISD has shown that our lead prevents the development of SLE in a mouse model of SLE and reduces the interferon signature in a benchtop test of human patient blood samples. ISD-Immunotech's approach is unique in targeting STING, a new molecular target for SLE, eliciting dampening of multiple events implicated in SLE including IFN-1 levels, other cytokines and apoptosis for broader efficacy. Furthermore, ISD seeks to reduce the complexity of SLE clinical development by using a benchtop test to pre-select severe patients who respond the therapy instead of targeting the heterogenous SLE population.
