- Results of experiments with BL-9020, a new antibody treatment, published in PLoS One -
BL-9020 is a novel monoclonal antibody treatment designed to prevent immune-mediated destruction of insulin-producing beta cells in the pancreas. It was developed to treat Type 1 diabetes in early stage patients, during what is known as the "honeymoon period," where the pancreatic beta cells have not been completely destroyed and continue to secrete insulin. BL-9020 targets NKp46, a unique target that is involved in the innate response against the pancreas. Pre-clinical studies in mouse models of Type 1 diabetes suggest that BL-9020 can inhibit beta cell death, thus preventing full maturation of the disease. This effect could significantly delay, and potentially prevent, the need for chronic insulin use by Type 1 diabetes patients, as well as provide a potential benefit in minimizing diabetes-related complications.
The new set of experiments shows that BL-9020 led to decreased levels of its target, NKp46, on murine NK cells, and specifically reduces the cytotoxic activity mediated by NKp46 in these cells. Consequently, BL-9020 significantly delayed the onset of diabetes and lowered the incidence of Type 1 diabetes in two different mouse models of diabetes. After a single treatment of BL-9020, hyperglycemia was significantly less severe. Moreover, following a repeated long-term treatment regimen of pre-diabetic mice, 70% of mice treated with BL-9020 remained diabetes-free throughout the experiment (25 weeks), compared to only 30% of control-treated mice.

BL-9020 is a first-in-class, monoclonal antibody that targets the Natural Killer (NK) receptor NKp46, which has been linked to Type 1 diabetes. Studies have shown that Natural Killer cells belonging to the innate immune system have a key role in the damage to pancreatic cells and, as a consequence, in the development of Type 1 diabetes.

About Type 1 Diabetes
Type 1 diabetes, which usually appears in children and adolescents, results from auto-immune destruction of the pancreatic beta cells producing insulin. This leads to a pathological, high level of sugar in the blood and urine. This hyperglycemia leads to high morbidity and mortality rates. Treatment of Type 1 diabetes is currently limited to lifetime administration of insulin by injection. The disease affects over 30 million people worldwide, and in 2012 the Type 1 diabetes market was estimated at over
