SEATTLE, June 10, 2016 /PRNewswire/ -- The Alliance for Children's Therapeutics today presented positive, updated data from an ex vivo study using KPI's Therapeutics/Kineta's lead drug Dalazatide for children and teens with lupus nephritis. The results were presented at the European League Against Rheumatism's 17th Annual Congress in London. Dr. Anne Stevens, a researcher at the Seattle Children's Research Institute, is leading the study and presented the work at the congress.
Lupus nephritis is an autoimmune disease which causes kidney inflammation and damage. Current medications are effective in reducing some of the inflammation associated with the disease, but they also suppress normal functions of the immune system, an undesirable side effect that is particularly problematic in children.
In particular, effector memory T cells associated with development of other autoimmune diseases such as psoriasis, inflammatory bowel diseases and rheumatoid arthritis appear to play an important role in lupus nephritis. T cells secrete inflammatory mediators (cytokines) that cause tissue damage and inflammation. T cells and B cells can amplify inflammatory responses thereby causing damage to the otherwise healthy tissue.
"New study data shows that patients with active lupus nephritis express higher levels of the Kv 1.3 channel, the target of Dalazatide, than do patients with inactive disease or healthy volunteers," said Dr. Stevens. "T cells from patients with active lupus are sensitive to blockade by Dalazatide, demonstrating ex vivo efficacy of the drug, and provide data to support the design of a clinical trial in patients with lupus," Dr. Stevens added.
"Lupus patients are in urgent need of novel and more effective therapies," said Dr. Charles Magness, President and CEO of KPI Therapeutics. "We are very encouraged by the positive effect Dalazatide has demonstrated in this study and are working to advance Dalazatide into lupus and lupus nephritis clinical trials."
The updated data also demonstrated that Dalazatide can decrease a group of cytokines functioning as biomarkers associated with active lupus disease. Importantly, these results show that Dalazatide has the ability to suppress these cytokines which are associated with disease inflammation and damage to lupus patients to a degree similar to traditional but toxic therapies such as cyclosporine A.
About Dalazatide Dalazatide completed a Phase 1B clinical trial in plaque psoriasis. It has a novel mechanism of action (MOA). Preclinical and clinical data have shown that Dalazatide is a selective and potent blocker of the voltage-gated Kv1.3 potassium channel - a key channel in the activation of effector-memory T cells. Effector memory T cells are implicated in the pathology of many autoimmune diseases. Dalazatide was the first specific Kv1.3 inhibitor advanced into human clinical trials. Dalazatide is being studied as a potential therapy for autoimmune diseases including lupus, ANCA Vasculitis, multiple sclerosis, psoriasis, psoriatic arthritis, rheumatoid arthritis, type 1 diabetes, inflammatory bowel diseases, and asthma. Dalazatide is being developed jointly with Kineta Inc.
